| 247 | Method and apparatus for dispensing liquid | US361803 | 1982-03-25 | US4519526A | 1985-05-28 | Gary Hillman |
| An anti-drip system for a dispenser in the form of a deformable conduit adapted to dispense a liquid, such as a photoresist, from a dispensing tip located at one end of the conduit includes a rigid housing which surrounds an intermediate portion of the conduit. The housing is closed except for a port which permits pressurized air to be supplied to and exhausted from the housing. At the commencement of a dispensing operation, the liquid is transported through the conduit as the housing is simultaneously pressurized, thereby crimping the intermediate portion of the conduit. At the conclusion of the dispensing operation, air pressure in the housing is simultaneously reduced, thereby allowing the conduit to expand and assume its natural substantially uncrimped shape. Expansion of the conduit creates a vacuum sufficient to suck back liquid which is being dispensed from the conduit. A pair of anti-drip systems may be utilized in combination with a pair of valves to actually meter liquid which is being dispensed through a deformable conduit. | ||||||

| 251 | Device for controlling the flow of fluid | US145798 | 1980-05-01 | US4335852A | 1982-06-22 | Ho Chow |
| A device to control the flow of fluid uses a cam and ratchet wheel. A valve is operated by the cam portion of the wheel, which bears against the valve stem causing it to open. Fluid flow causes a pawl to drive the ratchet portion of the wheel, rotating the wheel until the valve stem bears against a low point in the cam, permitting the valve to close. A part of the ratchet portion does not contain ratchet teeth, in which area the pawl cannot drive the wheel. In this area, the cam has an increasing radius from a radius corresponding to a closed valve, to a radius corresponding to a fully open valve. This permits manual control of fluid flow without disengagement of the device. | ||||||

| The device comprises a syphon which connects a reservoir to a collecting recipient. The reservoir is supplied with liquid through a valve. A tube extends the reservoir upwardly and carries a detector which checks the level situated just above the syphon. A second detector is placed at the outlet of the syphon. The two detectors are electrically connected to the control of the valve so as to close the valve when the liquid reaches the detector checking the level and to preclude the opening of the valve so long as the detector receives liquid issuing from the syphon. The amount of liquid poured upon each opening of the valve is thus always strictly the same.Application to the preparation of mixtures having a precise and adjustable concentration, such as a mixture of powdered milk and water. | ||||||
| 253 | Static metering pump | US55818 | 1979-07-09 | US4284210A | 1981-08-18 | Vladimir Horak |
| A static metering pump includes a pair of tanks, electrically operated inlet and outlet valves, liquid level sensors and controls which permit the alternate filling of a first of the tanks while permitting the discharging of liquid from a second of the tanks and then permitting the discharging of liquid from the first tank while filling the second tank. The cycle of filling and discharging of the tanks is repeated until a preselected volume of liquid is dispensed with precise metering. The two tanks are adapted to dispense the same volume of liquid in normal operation. Where the total volume of dispensed liquid called for includes a fraction of the normal volume of the tanks, one of the tanks is provided with a fractional liquid level sensor which may be preset to fill this tank initially to the fractional volume and to commence the metering operation by the discharge of this tank. | ||||||
| 254 | Controlled epoxy dispensing technique as related to transistor chip bonding | US448330 | 1974-03-05 | US3933187A | 1976-01-20 | Edward J. Marlinski |
| Apparatus and method for the uniform dispensing 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. | ||||||
| 255 | Method and apparatus for depositing precisely metered quantities of liquid on a surface | US15030971 | 1971-06-07 | US3810779A | 1974-05-14 | PICKETT C; MOLNAR J |
| A METHOD AND APPARATUS ARE DISCLOSED FOR DEPOSITING PRECISELY METERED QUANTITIES OF A LIQUID ON A PLATE OR LIKE SURFACE. A TUBULAR NEEDLE IS POSITIONED VERTICALLY IN A NON-DEPOSITION POSITION ABOVE THE SURFACE ON WHICH DEPOSITION IS TO BE EFFECTED, AND A POOL OF THE LIQUID IS MAINTAINED A DISTANCE ABOVE THE PLATE, THE SURFACE LEVEL OF TE POOL BEING SPACED AT OR SLIGHTLY BELOW THE LEVEL OF THE LOWER TIP END OF THE NEEDLE WITH THE LIQUID IN THE POOL BEING COMMUNICATED TO THE NEEDLE THROUGH A SUITABLE CONDUIT. DUE TO THE RELATIVE LOCATION OR POINTS OF ELEVATION OF THE LOWER TIP END OF THE NEEDLE IN SUCH NON-DEPOSITION POSITION AND THE POOL SURFACE, NO HEAD PRESSURE IS EXERTED IN THE LIQUID AT THE NEEDLE LOWER TIP END WHICH WOULD TEND TO CAUSE OUTFLOW OF LIQUID FROM THE NEEDLE. FURTHER, BACKFLOW OF LIQUID FROM THE NEEDLE AND CONDUIT TO THE POOL IS RESISTED BY CAPILLARY ACTION IN THE LIQUID DUE TO THE SIZE OF THE NEEDLE AND CONDUIT IN RELATION TO THE VISCOSITY OF THE LIQUID SO THAT THE NEEDLE AND CONDUIT ARE FILLED WITH LIQUID AT ALL TIMES. THE TUBULAR NEEDLE IS THEN STROKED DOWNWARDLY FROM ITS NON-DEPOSITION POSITION TOWARD THE PLATE AT A CERTAIN SPEED CREATING A HEAD PRESSURE IN THELIQUID AT THE NEEDLE LOWER TIP END BY REASON OF THE INCREASING DIFFERENTIAL BETWEEN THE POOL LEVEL AND THAT OF THE NEEDLE LOWER TIP END, AND CAUSING, DUE TO HEAD PRESSURE AND KINETIC ACTION, CREATION OF A BALL OF LIQUID OF CERTAIN SIZE AT THE LOWER TIP END DURING DOWNWARD MOVEMENT OF THE NEEDLE WITH THE BALL BEING RETAINED AT THE LOWER TIP END DUE TO CAPILLARY ACTION. THE DOWNWARD DISPLACEMENT OF THE NEEDLE IS TERMINATED IN A SECON OR DEPOSIT POSITION THEREOF WHEN THE BALL OF LIQUID CONTACTS THE PLATE ON WHICH DEPOSITIONS IS TO TAKE PLACE, AND THE ADHESIVE ATTRACTION OF THE PLATE DRAWS THE BALL OF LIQUID FROM THE NEEDLE TIP WHEREUPON THE NEEDLE IS RETRACTED UPWARDLY TO ITS FIRST POSITION LEAVING DEPOSITED ON THE PLATE A PRECISELY METERED QUANTITY OF LIQUID. APPARATUS FOR DEPOSITING THE LIQUID ON THE PLATE IN A PLURALITY OF SEPARATE DEPOSITS IN A SUITABLE MATRIX ARRANGEMENT ALSO IS DISCLOSED.
