| 201 | Multiple envelope detector | US8746 | 1993-01-25 | US5331151A | 1994-07-19 | Don W. Cochran; James E. Triner |
| A parcel detection system works in connection with a stream of parcels, such as might be encountered in connection with bulk mail sorting apparatii. A presence of multiple parcels traveling adjacent one to another is detected with a line scan charge coupled device. A transducer array is disposed perpendicularly to the stream flow. Specular illumination of edges of the parcels is completed to facilitate capturing an image in the CCD array. An analog signal, obtained from the array, includes information representative of a number of adjacent parcels. This information is processed to provide a signal representative of a number of parcels traveling adjacent to one another in the stream. | ||||||
| 202 | Method of and apparatus for detecting and counting articles | US812010 | 1991-12-23 | US5313508A | 1994-05-17 | John L. Ditman; David J. Holmes, III |
| A method and apparatus for counting irregularly-shaped articles. A pair of light sources are provided at a sensing plane through which articles to be counted pass. Each of the light sources emits a light beam that is at an angle to the other light beam, such as an angle of about 90.degree.. Corresponding light sensors are positioned opposite the respective light sources to receive the light signals as the articles pass through the sensing plane. A time division multiplex circuit is provided to alternately operate the light sources, and the outputs from the respective light detectors are summed to provide a unitary signal that is provided to a counter to maintain a count of the number of articles passing through the sensing plane. The system provides combined output signals that are substantially independent of the orientation of the article at the sensing plane. | ||||||

| Articles, moving along a delivery path, are counted by directing a stream of pressurized air toward one major surface of the passing articles, the direction of the air stream being transverse to the direction of travel. Sensors arranged about the air stream detect the acoustic signal which varies with changes in the profile of the passing articles, exemplified by signatures. The detected acoustic signal is divided into a plurality of frequency ranges which, in one preferred emboidment, are averaged to reduce the effect of noise which may be present in only limited ones of the frequency bands. The averaged signals are then compared against thresholds to determine the instantaneous state of the articles, exemplified by a signature stream, to generate count signals. | ||||||
| 204 | Apparatus for detecting number of packs included in bundle | US453837 | 1989-12-20 | US5017773A | 1991-05-21 | Masamichi Sato |
| A laser beam emitted from a semiconductor laser is radiated and scanned on a bundle of paper materials which is being conveyed, and the laser beam reflected by the bundle is received by a plurality of photocells to be converted to electrical signals. A signal synthesizer synthesizes the electrical signals output from the photocells. A binary circuit binarizes the synthesized signal to generate a boundary signal corresponding to a boundary between packs included in the bundle. A CPU detects the number of packs included in the bundle on the basis of the number of boundary signals. | ||||||
| 205 | Measuring apparatus | US271177 | 1988-11-14 | US4890500A | 1990-01-02 | Alan F. Giles |
| Apparatus for detecting and counting flowable particulates having means for feeding these particulates at a uniform speed through a measuring area, defined by radiation emitting and sensing means which are arranged in a plane transverse to the feeding direction of the particulates and such that an even number of fan shaped, overlapping arrays of sensing beams can be generated between the emitting and sensing means, each pair of arrays having two lines of symmetry: the one connecting the convergence points of the fan shaped arrays and the other being the perpendicular bisector thereof. | ||||||
| 206 | Laundry transfer and counting apparatus | US91003 | 1987-08-31 | US4849999A | 1989-07-18 | Jerry W. Humphreys; Michael S. Radler |
| The invention includes an apparatus for and method of moving textile articles such as pieces of laundry or the like comprising an enclosed passageway having two opposing open ends, and at least one bend between the two open ends; a vacuum source coupled with one of the two open ends and developing a subatmospheric pressure along the passageway and at the other open end of the passageway to draw textile articles into the other open end and through the passageway to the one open end; and a sensor located at the one bend and sensing textile articles drawn through the passageway. The sensor is coupled with an appropriate counter for accumulating a count of successive textile articles drawn through the passageway. A delay circuit is included between the sensor and the accumulator to inhibit successive detector outputs for a selectable but fixed time period, regardless of the size of the textile articles being passed and counted. The subatmospheric pressure developed at the remote open end of the passageway initially receiving the textile articles is sufficient to lift up into the open end and draw through the passageway articles raised to just beneath that opening. | ||||||

| 209 | Photoelectric article sensor with facing reflectors | US649098 | 1984-09-10 | US4634855A | 1987-01-06 | Kenneth D. Friend; Vijay M. Dharia |
| A sensor for counting articles, such as seeds, moving through a conduit includes an array of infrared LEDs generating a uniform diffuse beam of radiation which entirely illuminates a cross sectional volume of the conduit. The beam is detected by a planar photo diode which extends across the opposite side of the conduit. A pair of mirrors extend along opposite sides of the conduit between the array and the photo diodes. Slits narrow the beam and limit the amount of radiation which can impinge upon the photo diode. The signal from the photo diode is integrated by a signal processing unit so that the sensor can count a plurality of seeds in a group of seeds which simultaneously pass through the beam. The signal processing unit automatically compensates for changes in the steady state photo-diode output and for changes in seed size. | ||||||
| 210 | Article density sensing | US42694 | 1979-05-25 | US4410078A | 1983-10-18 | Winston E. Shields; Robert F. Lantz, II |
| In a mass conveying system a variable branch of an electrical bridge network is sensitive to changes in the numerical density of articles within a predetermined portion of the system. The bridge network is responsive to an imbalance therein to generate a signal corresponding to the imbalance. Means responsive to the signal act to control delivery of articles to the system. | ||||||

| 212 | Pneumatic penetration sensor for oil drilling | US340824 | 1982-01-19 | US4387295A | 1983-06-07 | George M. Minichiello |
| A device for accurately measuring the position of a traveling block in a drilling rig or the like which is supported by means of a cable wrapped around a drum winch assembly. A pneumatic sensor coupled to the drum provides a predetermined number of output pulses per revolution of the drum. During the paying out of a first layer of cable from the drum, the sensor pulses are coupled to a first pneumatic counter, which is preset so as to provide an output pulse corresponding to a predetermined increment of motion during the paying out of the first layer. Additional counters are provided with different preset limits so that they will provide output pulses corresponding to the predetermined increment of motion during the paying out of second and additional layers of cable from the drum. As the cable is paid out or wound in, the output of the drum motion sensor is coupled to the appropriate pneumatic counter by means of a switching assembly. The switching assembly includes additional pneumatic counters for counting the number of pulses provided by the drum motion sensor during the paying out of an entire layer of cable from the drum and switching valves which are controlled by the additional counters. The arrangement enables accurate measurements to be made based upon drum revolution, despite the fact that the amount of traveling block motion will be different during the paying out of different layers of cable, due to the different diameters of the layers. | ||||||
| 213 | Method and apparatus for counting small objects suspended in a liquid stream | US104596 | 1979-12-17 | US4294542A | 1981-10-13 | Gary M. Strauss |
| The present invention is a method and apparatus for counting discrete small objects suspended in a liquid stream. It comprises a source of flowing liquid having sufficient known velocity to maintain the objects in suspension, a means for introducing the objects into the liquid stream, and a calibrated turbidity measuring device. The outflow may be automatically shifted from one receiving means to another when a predetermined object count is reached. The method is particularly useful when counting living objects, such as fish fry or post-larval shrimp, since it eliminates the trauma of handling and is much faster than hand counting. | ||||||
| 214 | Scanner for detecting and indicating missing and wedged articles in slat-type counting machine | US66604 | 1979-08-15 | US4241293A | 1980-12-23 | Charles F. Bross |
| A slat-type article counting machine includes slats provided with cavities which carry the articles, an exact count of which are designed to be discharged into bottles or containers. Each cavity defines a hole which penetrates the entire slat depth. Two pairs of scanners are mounted to the machine, one for detecting missing articles from cavities and the other for detecting articles wedged or blocked therein. A pair of scanners comprises sensors which include an array board having multiple light-emitting diodes which project light beams through the holes provided in the cavities to thereby strike photoelectric cells mounted to another array board, which photoelectric cells generate signals which cooperate with sensing and logic circuits for effecting visual and audible means for indicating miscounts due to empty or blocked cavities. A wide range of auxiliary operations and functions may additionally be initiated by the signals. | ||||||

| 217 | Aquatic animal counting | US722417 | 1976-09-13 | US4095092A | 1978-06-13 | Gregor N. Neff |
| Aquatic animals (e.g., fish) are counted in the same operation in which the fish are sorted as to size. This minimizes the labor required for counting because it is the same labor as that used for sorting the animals. A grading or sorting barrier is provided with a plurality of parallel holes or passageways, and the fish are urged towards the barrier. Mounted so as to extend across each of the holes is a flexible electrode which normally forms a closed electrical switch. When the animal passes through the hole, it hits the electrode and thus opens the switch. This creates a signal which is stored in an electrical memory. The information stored in the memory is read out sequentially and counted by an electronic counter. The size of the holes in the grading barrier is such that only animals smaller than a pre-determined size will pass through. This serves two functions; it sorts the larger fish from the smaller ones, and allows the operator to set the size openings at a level such that the smallest fish will be counted as they pass through the openings. Then, if desired, the openings can be enlarged, either by substituting a grading barrier with larger holes, or by means of a device which enlarges the holes mechanically, and the remainder of the fish can be counted. The grading barrier can be used when it is horizontal, either in the water or out of the water, so that gravity assists the fish in moving downwardly towards the barrier and through it. The barrier also can be vertical and placed so as to form a wall between two compartments for the fish. | ||||||
| 218 | Method and apparatus for analyzing harvester efficiency | US414914 | 1973-11-12 | US4000398A | 1976-12-28 | Charles C. Conner |
| Kernels of grain or other particulate harvester product, trapped with chaff and other trash being returned to the ground, are caused to drop onto an impact-sensitive transducer which thereupon produces corresponding electric signals which are counted and related to harvester ground speed and header width to provide a read-out of quantity per area of particulate product lost. | ||||||

| 220 | Apparatus for high-speed accurate counting and handling of discrete objects such as tablets | US613681 | 1975-09-15 | US3982865A | 1976-09-28 | Jim Mills Adams; Edward Francis DE Zabala |
| There is disclosed a highly accurate counting and handling arrangement particularly adaptable to large-volume, high-speed multiple-output apparatus producing discrete, solid particular objects, such as tablets. Sensing means, preferably retroreflective optical sensors, fluidic sensors or strain-gauge sensing arrangements, are employed in associated with existing apparatus to detect each object at the point where the objects are substantially completely formed. The signals generated by the individual sensors are received by a control counter arrangement which provides a continuous separate displayed counting for each sensor employed. The control counter arrangement has provision for separately presetting the maximum desired count of sensed objects for each sensor employed. A gated dispensing assembly is additionally provided in association with each sensor employed which is adapted to predeterminably control the procession of the objects from their point of virtual completion to a pre-established destination under the supervision of the respective separate maximum preset facility of the control counter arrangement. | ||||||
