Abstract: An apparatus for aseptically filling premanufactured, presterilized, flexible containers, connected in a continuous web, includes a chamber with an inlet mouth for receiving empty containers seriatim, and an outlet mouth for dispensing filled containers seriatim. The inlet and outlet mouths have respective seals for sealing to the surface of the containers to prevent entry of contaminants into the chamber. This chamber is partitioned to form a spraying compartment, adjacent to the inlet mouth, and a filling compartment, adjacent to the outlet mouth, with a drying compartment therebetween. A sterilizing agent is continuously sprayed, as a mist, into the spraying compartment to coat the exterior of the containers with the sterilizing agent as they are serially advanced through the chamber. This mist also provides an aseptic barrier between the inlet mouth and the drying compartment.

Abstract: A portable air-operated apparatus for cleaning, flushing, and filling a liquid cooling system of an internal combustion engine. The cooling system is cleaned by sequentially moving liquid in opposite directions in the cooling system. The apparatus also functions to pressure check the cooling system for leaks, to flush the cooling system of cleaning liquid and foreign matter, and filling the cooling system with new coolant liquid. The apparatus has an air-operated reciprocating piston pump assembly operable to agitate or sequentially move liquid in opposite directions and pump liquid into the cooling system. The pump assembly delivers the liquid to a manifold connected to an input hose coupled to the liquid cooling system. A control valve connected to the manifold is operable to direct an external source of liquid under pressure to the manifold or connect a reservoir carried by the apparatus to the manifold.

Abstract: A method of washing a keg and filling it with beer which comprises giving the keg first and second washes at first and second washing stations, filling the keg with steam and carbon dioxide at the second washing station after washing and then moving the keg to a filling station and filling the keg with beer at said filling station while allowing the carbon dioxide in the keg to escape through a pressure relief valve.

Abstract: In a machine for washing or filling a beer keg via a head having a movable probe to open the valve of the keg closure unit, a complementary magnetic carried by the probe and the head for indicating when the probe is in a fully extended position within the head to open the valve and to seal with the closure unit.

Abstract: An automatic tumble dumper for automatically removing the electrolyte from lead-acid storage batteries and particularly batteries intended for automotive use is disclosed. The device comprises carrier means adapted to transport the batteries through the system. Once the batteries are inside the unit, upset means automatically turn them first onto their side and then invert them so that the bulk of the electrolyte passively drains out. To achieve complete electrolyte removal, the batteries are jostled via a jostling means which cooperates with said carrier to actively shake the batteries as they travel through the device. At the conclusion of this shaking, now drained batteries are returned to an upright position and travel out of the machine for further processing.

Abstract: A portable air-operated apparatus for cleaning, flushing, and filling a liquid cooling system of an internal combustion engine. The apparatus has an air-operated reciprocating piston pump assembly operable to agitate or sequentially move liquid in opposite directions and pump liquid into the cooling system. The pump assembly delivers the liquid to a manifold connected to an input hose coupled to the liquid cooling system. A control valve connected to the manifold is operable to direct an external source of liquid under pressure to the manifold or connect a reservoir carried by the apparatus to the manifold. The manifold has a check valve for controlling one-way forward flow of liquid from the pump to the input hose. A by-pass hose connects the control valve and manifold to by-pass the check valve to allow reverse flow of liquid in the input hose back to the pump assembly so that the pump assembly will effect a sequential forward and reverse flow of liquid in the cooling system.

Abstract: A portable machine for servicing small animal cage litter trays which is independent of water and waste connections.

Abstract: A continuous sampler having a predetermined number of sample containers in which a sample from a liquid flow is deposited at predetermined intervals of time. Samples are deposited in sample containers in a sampling position and the sample containers are stepped once each interval of time through a path of travel until they assume a cleaning position adjacent to the sampling position. A sample removal probe and a wash probe is lowered through an access opening in the sample container in the cleaning position and a source of washing solution is coupled to the wash probe and means for removing the contents of the sample container is coupled to the sample removal probe. Means for controlling the position of the wash and sample removal probes in a position inside the sample container in the cleaning position and in a position remote therefrom, as well as controlling the means for removing samples therefrom and the means coupling a wash solution thereto is provided.

Abstract: A dynamic scattering liquid crystal cell can be filled from a single fill port by evacuating the cell, filling with a solution of an ionic dopant in a volatile solvent, evaporating the solvent and refilling under vacuum with the dynamic scattering liquid crystal composition. Ion hang-up is avoided and only a single volume of the liquid crystal composition is required to fill the cell.

Abstract: Methods and apparatus for the simultaneous performance of a series of analyses upon a multiplicity of samples disposed in an upright array of cuvette receptacles therefor, said array being in mating facial juxtaposition with similarly disposed arrays of reagent dispensing means, sample dispensing means, treatment means, analytic means and receptacle cleaning means such that individual operative means are coordinately positioned for simultaneous engagement with a plurality of receptacles; and executing steps in the analytic sequence by moving the receptacle array to a series of spaced positions sequentially whereby individual receptacles are simultaneously progressed in a series of steps through a cycle of sample treatment and analysis to cleaning.
