| 181 | Method and apparatus for metering liquids | US281049 | 1981-07-07 | US4462760A | 1984-07-31 | Tony R. Sarich; Kenneth N. Johnsen; Michael L. McKay |
| A method and apparatus for delivering metered quantities of liquid wherein the liquid is circulated through a chamber to fill the chamber with liquid and circulation is temporarily terminated with the chamber filled with liquid. While circulation is terminated gas under pressure is admitted to the chamber to displace liquid therefrom through a discharge port. The quantity of liquid displaced is controlled by regulating the volume of the chamber and/or by regulating the relative disposition in the chamber of the point of entry of the gas and point of discharge of the liquid. | ||||||

| A method of and apparatus for measuring or measuring-out a predetermined volume of a liquid flowing through a conduit or line, comprising a first conduit section containing a measurement path and at one end connected with the outlet conduit of a connection element which interconnects a first inlet conduit and a second inlet conduit. The first conduit section is operatively connected at its other end through the agency of a first valve with the low pressure side of a pump device. The first inlet conduit is continuously connected with a liquid container via a second conduit section which causes a dynamic pressure drop in the flowing liquid. Additionally, the second inlet conduit is continuously connected with a fluid container and the fluid container is connected via a second valve with a compartment, whereas the liquid container is continuously connected with the compartment and the high pressure side of the pump device opens into said compartment. | ||||||
| 186 | Method for bonding semiconductor chips | US541831 | 1975-01-17 | US3963551A | 1976-06-15 | Edward J. Marlinski |
| Apparatus and method for the uniform dipensing of a conductive epoxy binder in hybrid microcircuit applications. A method is disclosed of uniformly pressurizing a conductive epoxy binder through a small orifice until a droplet of fixed volume forms, setting a predetermined gap size between a contact pad and the droplet in order to control the shape and size of the epoxy droplet left on the pad as the droplet touches it, and then releasing the pressure while reciprocating the dispenser from the pad. Also, apparatus, including a cylindrical limiting means attached to the dispenser tip, is disclosed for ensuring the gap size is constant. Other embodiments of the limiting means provide for the use of a relieved section which assists in preventing contamination and for adjusting means operable to vary the gap size. | ||||||
| 187 | One-shot metering valve | US39560173 | 1973-09-10 | US3881637A | 1975-05-06 | BROWNE KENNETH A |
| A metering valve for discharging a predetermined amount of liquid where the valve is actuated by a negative pressure and, after having once been actuated to discharge a predetermined amount of liquid, cannot thereafter be again actuated until a predetermined time has elapsed from the last attempted actuation of the valve. The exemplary embodiment is especially adapted for use in conjunction with a reciprocating piston pump whereby predetermined amounts of a chemical can be discharged into the pumped liquid during only the first reciprocating pump stroke with no further chemical discharge occurring until the pump has been in an idle state for a predetermined time period.

| 188 | Method of increasing the measuring resolution of a flow measuring instrument where the flow is divided into sections of well defined volume | US24746172 | 1972-04-25 | US3815414A | 1974-06-11 | HELLSTROM K |
| The resolution of a device, which measures the flow of liquid in a tube by producing a series of signals each of which corresponds to the passage through the tube of a predetermined volume of liquid, is increased by the introduction of additional signals at a rate which is a predetermined multiple of the basic signals and utilizing these additional signals, coordinated with the basic signals, to indicate the passage through the tube of fractional amounts of the volume measured by each of the basic signals.

| 189 | Toggle necklock | US3794220D | 1972-04-05 | US3794220A | 1974-02-26 | VALLE H |
| A bottle dispenser mounted on the open end of a bottle has a rotatable threaded shaft extending into the neck of the bottle with a toggle nut threaded onto the shaft for combined rotation and translation movement and a pair of oppositely extending wings pivotally mounted on the toggle nut. The wings are expanded to engage the inner surface of the bottle neck and the shaft rotated so that the toggle nut moves therealong to lockingly engage the expanded wing members against the inner surface of the bottle neck.

| 190 | Device for automatic sampling and measurement of liquid volumes | US3769841D | 1971-11-04 | US3769841A | 1973-11-06 | THULIN S |
| Automatic sampling and measurement device for liquid volumes in which the orifice of a tube is submersible in the liquid to be sampled, there being above the liquid surface an appropriate overpressure in relation to the pressure at the other end of the tube, there being further placed a detector at a defined level of the tube, the volume in the tube between its orifice submersible in the liquid and said level corresponding to the liquid volume to be sampled, the detector being caused to activate a device which raises the tube orifice out of the liquid, when the interface between liquid and gas in the tube reaches said level, after which the overpressure forces the so measured liquid volume out through the other end of the tube.

| 191 | Particle counting apparatus | US3769582D | 1971-11-01 | US3769582A | 1973-10-30 | SCHOEN K |
| An apparatus for counting particles suspended in a fluid, comprising a conductivity cell having air vent means and means defining an electrical resistance measuring path. Mechanism serves to selectively open and close the air vent means. There is also provided a flask containing a quantity of particle containing fluid and a conveying system for transporting a quantity of such particle containing fluid from the flask through said electrical resistance measuring path of said conductivity cell. Each particle upon passing said electrical resistance measuring path brings about a measurable change of the resistance of such measuring path. There is further provided counting mechanism for electrically counting changes in such resistance of the measuring path, this counting mechanism including a volumetrically calibrated measuring tube. Electric circuit means including first and second read-out means are spaced at a predetermined distance from one another along said volumetrically calibrated measuring tube, said electric circuit means generating a starting signal commencing the counting operation and causing the aforesaid mechanism to tightly close said air vent means and further generating a switch-out signal for terminating the counting operation and causing said mechanism to open said air vent means.
