Abstract: A connector is provided for attachment of a syringe to a dispenser adapted to provide measured quantities of pressured gas to the syringe to displace the contents of the syringe in measured drops. The connector includes a flexible conduit attached at one end to the dispenser and attached at its opposite end to the filling end of a syringe while gripping the oppositely disposed projections, or "ears", of the syringe. There is an externally threaded tube at the syringe end of the flexible conduit, terminated by a stopper member which has a cylindrical end portion sized to fit loosely within the filling end of the syringe, which end portion is joined to a sealing flange. The sealing flange abuts the flat surface at the filling end of the syringe while the syringe "ears" are retained within oppositely disposed channels after a knurled ring on the externally threaded tubular member is rotated.

Abstract: The process and apparatus for effecting savings of compressed injection gs such as oxygen or nitrogen when injecting solids such as burnt lime pneumatically into a receiving vessel, such as the blow-line to steel melt has a solids conveying system, a compressed gas supply source and a conduit and valve system functioning in a sequence, by which the compressed gas upon termination of the procedure is collected and thereupon is recycled. The system is equipped with at least one pressure-reservoir to collect the compressed gas from the previous procedure for recycling it.The pressure reservoir is subdivided by a reciprocating divider such as a membrane or a reciprocating piston to subdivide it into two parts of variable volumes, the divider is pushed by the returning compressed saved gas from one wall of the reservoir to the other. Highly compressed gas is blown into the empty part of the reservoir to increase the pressure upon the returned gas.

Abstract: A continuously operating gasifying vessel is supplied with a combustible particulate material from a source of such material through two cyclically operating conveying tubes each of which has a diaphragm member in its interior. The diaphragm member subdivides the interior of each of the conveying tubes into a first compartment which communicates with the supply and with the vessel, and a second compartment which surrounds the first compartment. A first valve is interposed between the source and the first compartment, and a second valve is interposed between the first compartment and the vessel. When the first valve is opened and the second closed, material is introduced into the first compartment, and when the first valve is closed and the second valve is opened, the material is discharged into the vessel at an elevated pressure. To elevate the pressure in the first compartment, a pressurized fluid is introduced thereinto.

Abstract: An atomizer assembly comprises a nozzle mounted in a push-button mounted on a tubular extension to a first piston of the assembly. The first piston is slidable in a first cylinder or pump chamber and defines a seat of a valve. A valve member co-operating with the seat forms part of a second piston slidable in a second cylinder defined by the first piston. Depression of the push-button causes pressure in the pump chamber to increase and at a certain point the valve member is lifted from the seat so that liquid under pressure passes to the nozzle.

Abstract: A programmed fluid sampling and analysis apparatus and method includes apparatus for the programmer controlled sampling of a fluid stream in order to subject the fluid sample to an automated analysis of the ion or molecular concentrations of the chemicals of the sampled fluid. The sampled stream and appropriate reagents are impelled by a gas through the apparatus according to a program so that the sample fluid and reagents ultimately mix in a vessel wherein the mixtures are analyzed by a colorimeter or by specific element-ion sensitive probes connected to electronic amplifying and recording equipment. A programmed analysis of the sensor output is provided on a strip chart recorder. The apparatus includes a fluid sampling and transport device for delivering an aliquot of sampled fluid to a reaction chamber under the influence of a programmed pulse of compressed air. An aliquot of one or more reagents is similarly provided to the reaction chamber from a reagent sampling and transport device.

Abstract: An automatic drink dispensing apparatus wherein drinks are poured to prescribed formulations following proper operation of "selected" buttons on a keyboard console. The ingredients of the drink are simultaneously poured so that the length of pour is determined by the length of time that it takes to pour the major ingredient so as to produce extreme speed in dispensing drinks and thus raising the gross operation.Finally, solid state electronic means in the form of semi-conductor "logic gates" are provided and arranged in a unique fashion to permit the apparatus to perform the above-noted improvements.

Abstract: A bag filling machine has a closed chamber with an inlet valve. The inlet valve includes an outer casing and a slidably mounted inner chamber which, when in its lower position, extends down into the chamber to limit the level of the material passing through aligned openings in the two casings. When the inner casing slides upwardly, the inner casing serves as a gate to cut off the flow of material and at the same time the upward movement of the lower edge of the inner casing permits the material within it to drop down into the chamber. A felt liner is disposed between the two casings.

Abstract: Apparatus for drawing liquids into, and expelling liquids from, a pipette including a housing comprising a hand-held pistol grip to which is connected a pipette-supporting portion. Valve means mounted on the pistol grip beneath two fingers of the user permit selective application of pressure or vacuum to one end of the pipette for drawing the liquid into, and expelling the liquid from, the pipette.

Abstract: Method and device for metering and dispensing viscous or partly fluid materials in which the fluid material is flowed downwardly as a column through a tube, is separated into portions by injecting gas into the column to form bubbles spaced along the length of the fluid column and discharging the separated portions from an outlet opening of the tube. The apparatus includes a tube together with a controlled fluid material supply, a gas supply, a gas inlet for generating bubbles to separate fluid passing through the tube into portions and an outlet from the tube for discharging separated portions of fluid. The fluid portions may be collected and maintained separate by deposition in a displaceable medium such as air, liquid or powder, or by separate containers for each portion. The portions deposited in powder may pick up powder in the form of a non-tacky coating.

Abstract: A container of the chemical to be dispensed is supported in inverted position in the toilet flush tank with the mouth of the container opening downwardly. The dispensing closure is sealingly associated with and axially adjustable on the container around its mouth. The closure has an open lower end normally immersed in the water within the tank and separated by a partition from the metering chamber within the upper end of the closure communicating with the container mouth. The liquid is delivered by gravity into the metering chamber, to a depth to cover said mouth. Pressurized air delivered from the pump chamber into the upper portion of the metering chamber above the mouth exerts a pressure on the liquid within the metering chamber to force the same out through a discharge port and tube leading to the tank overflow pipe.

Abstract: A liquid dispensing system including a liquid supply manifold connected to a liquid dispensing reservoir. A check valve is interposed between the manifold and the reservoir to permit liquid flow from the manifold to the reservoir and to prevent reverse flow from the reservoir to the manifold. A dispenser outlet is connected to the reservoir and a dispenser valve is provided thereat to control liquid flow from the dispenser outlet. A source of air under pressure is connected to the reservoir and a control valve is provided to alternately place the reservoir into communication with the source of air under pressure and then subsequently cut off the source of air pressure and place the reservoir into communication with the atmosphere. During the period the reservoir is placed in communication with the air under pressure, the liquid dispenser valve is opened to thereby cause a quantity of liquid to be dispensed from the reservoir out through the dispenser outlet.
