Abstract:
The present invention is a gas separator for separating a gas mixture into a product gas. The gas separator has an adsorbent bed including a separation chamber with first and second ports and a molecular sieve material contained in the separation chamber. A first pumping chamber is connected to the first port. A first valve regulates a flow of the gas mixture between the first port and the first pumping chamber. A first piston is located in the first pumping chamber. A second pumping chamber is connected to the second port. A second valve regulates a flow of the product gas between the second port and the second pumping chamber. A second piston is located in the second pumping chamber. A drive system coordinates operation of the first and second pistons and the first and second valves in a cycle including a pressurization stage, a gas shift stage, and a depressurization stage.

Abstract:
A filter forming and joining apparatus of the present invention automatically forms a succession of metal-free cylindrical filter elements from a pleat block of pleated filter material, each pleat block having a first end pleat at a first end of the pleat block and a second end pleat at a second end of the pleat block. The apparatus including a pleat block isolator for isolating successive individual pleat blocks from other pleat blocks in a succession of pleat blocks in preparation for filter formation, a filter former that manipulates each isolated pleat block along a forming path into a hollow cylinder shape, the hollow cylinder-shaped isolated pleat block having a first end pleat and a second end pleat positioned adjacent each other, and a filter joiner that bonds together the adjacent first and second end pleats of each hollow cylinder-shaped isolated pleat block producing a metal-free cylindrical filter element.

Abstract:
Apparatus for filling sterile containers is disclosed which defines an elongated but narrow sterile zone in which a number of operating stations are disposed. An elongated vertical wall is armed by an elongated frame and a cabinet type enclosure cooperates with the vertical wall to define the sterile zone. The plurality of operating stations are disposed in sequential relation over the length of the sterile zone, and an elongated container conveyor is disposed within the sterile zone to convey the containers through the plurality of operating stations. The conveyer is vertically oriented, consisting an endless belt mounted on end wheels that rotate on horizontal axes. Each of the operating stations includes an operating portion disposed within the sterile zone. Actuating means are included for each of the operating stations as well as the elongated conveys, each of which is disposed outside the sterile zone. Connecting means operabably connect each of the actuating means outside the sterile zone through the vertical wall to the associated operating station within the sterile zone.

Abstract:
A product pump for pumping separated product gas from an oxygen concentrator which produces oxygen-rich product gas by utilizing a vacuum swing adsorption (VSA) process. The oxygen concentrator comprises a cartridge containing an adsorbent material for separating the product gas from ambient air, a vacuum pump which provides a vacuum source, a valve for selectively connecting the vacuum pump to the cartridge and product pump, and a reservoir. The product pump comprises a pumping chamber having a product gas inlet and a product gas outlet, a piston movable in the chamber, a vacuum inlet in the chamber on an opposite side of the piston from the product gas inlet and outlet for providing a vacuum to cause the piston to draw product gas through the product gas inlet into the chamber, and a spring for providing a spring force to force the product gas out the product gas outlet.

An oxygen concentrator comprises a vacuum swing adsorption (VSA) gas separation system which includes a cartridge containing a mass of adsorbent material for producing oxygen, a drive which activates the gas separation system, and a power source comprising a mass. A ratio of the mass of the power source to a flow rate of oxygen produced by the oxygen concentrator is between 0. 047 and 0. 29 kg/LPMhr.
