| A source (1) is equipped with a conveying device (4) for discharging the particles (2, 2a) at adjustable rates per unit time. A crystal (16), formed from doped particles, is withdrawn from the melting crucible (13) at a predetermined rate per unit time. So that the control process can be conducted smoothly over prolonged periods of time with precise doping, the particles (2, 2a) are fed single file to the melting crucible (13) and counted by at least one sensor (21, 22). The sequence of count pulses is sent to a counter (25) and compared there with a corresponding sequence of reference input pulses. The comparison signal formed from the count pulses and the reference input pulses is used, in accordance with its sign, as a control signal for adjusting the amount of particles being discharged per unit time from source (1) to correspond to the reference value. | ||||||
| 124 | High speed, high accuracy parts counting system | US419171 | 1995-04-10 | US5502755A | 1996-03-26 | Thomas O. Nagel; Daniel J. Ellis |
| A high speed, high accuracy parts counting system is disclosed. The new system utilizes known types of centrifugal feeder devices with novel modifications relating to the sensing and control of individual workpieces, enabling workpieces to be counted and processed at much greater speeds than before, while equaling or improving accuracy. The new system makes no attempt to separate individual workpieces for counting purposes, enabling operations to be carried out at greater speeds. Counting of workpieces in an unseparated group of such workpieces is accomplished by electronic measurement of movement of the centrifugal feeder between the leading and trailing edges of a group of unseparated workpieces. The counting of a predetermined number of workpieces is thus a function of the counting of pulses and is independent of the separation or non-separation of workpieces during counting. Provision is also made for high speed collection and discharge of counted groups of workpieces. | ||||||

| 127 | Contact type paper counter | US322536 | 1989-03-13 | US4974237A | 1990-11-27 | Richard Grabowski |
| A contact sensor apparatus counts associated sheet products as they pass over a generally planar surface. a vacuum source draws a bottom surface of a sheet product onto the planar surface. A contact member is selectively deflected through engagement with the sheet product and deflects upwardly at the passage of the trailing edge of the sheet product. The contact member is connected to a sheet of piezoelectric material that is distorted upon deflection of the contact member. This produces an electrical charge representative of passage of paper over the sensor apparatus. | ||||||

In order to avoid connecting two lines to the ring-jet sensor (24), the said ring-jet sensor and also the pressure sensor (37), are each connected, in parallel, to one branch line (23, 35). The branch lines (23, 35) can carry either compressed air or suction air. | ||||||
| 129 | Method of counting articles supplied on a conveyor track in a random pattern | US272212 | 1988-11-16 | US4900915A | 1990-02-13 | Johannes H. de Hoog; Andre Deen; Peter J. Wever |
| A method of counting, in real time, articles supplied on a conveyor track in a random pattern is disclosed. The method comprises forming an image of the articles present in a counting zone by means of an image pick-up device, which counting zone corresponds to a periodic, elongated image of the image pick-up device, which image extends essentially transversely to the direction of movement of the conveyor track. The elongated image is converted into a binary image composed of a row of image elements, each with its own grey value, which binary image is obtained by assigning a first logic state to image elements having a grey value above a pre-determined threshold value and a second logic state to image elements below this threshold value. The invention is characterized by determining whether an article arrived in the counting zone, whether the article subsequently reaches a minimum width in the image, and whether the article leaves the counting zone again, whereby a count signal is produced when the article leaves the counting zone. | ||||||

| 131 | Light counting system for convex articles | US909994 | 1986-09-22 | US4877954A | 1989-10-31 | Arnold I. Neuman; Thomas D. Heidt; Andrew Bergman; James Wickstead |
| An apparatus for counting hangers having a convex surface includes a housing having a central light source carried by the housing for projecting a light beam on the convex surface. A pair of spaced light detectors is positioned on the housing substantially on opposed sides of the central light source, the spaced light detectors detect light reflected from the convex surface. A detecting circuit is connected to the pair of spaced light detectors and detects the sequence of reflected light beams, and then determines whether the detected sequence is a sequence of reflected light beams characteristic of the relative displacement of the housing and the convex surface when the housing or the convex surface is displaced in substantially the direction of the space between the pair of opposed light detectors. | ||||||

| Device and method for detecting the contour or shape of one or more articles by projecting multiple light beams on a different portions of an atricle, and measuring the level of light reflected from the article. The amount of light reflected indicates the distance of the light emitter/detector from the article.

The readings may be processed to provide an indication of the number and size of articles passing by the sensors. The device may be placed over a conveyor carrying objects to be counted and/or sized. | ||||||

| The invention provides a method and apparatus for manually counting pills or similar objects. Pills in excess of a required number are deposited in a counting area which has the general shape of an equilateral triangle and is defined by walls which surround all but a small open peripheral range of the area. The excess pills are separated from the required number on the counting area, and the user tilts the apparatus to cause the excess to slide out of the area through the open peripheral range while retaining the required number in the counting area. The user then tilts the apparatus to cause the required number of pills to slide out of the area through the open peripheral range. | ||||||

| 136 | Article or seed counter | US649108 | 1984-09-10 | US4635215A | 1987-01-06 | Kenneth D. Friend |
| 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. | ||||||
