Abstract: The filter contains about 1-15% lithium hydroxide and about 85-99% hopcalite material, having a particle size of approximately 20 to 100 mesh, and can be used in combination with a chemical oxygen generator for removing chlorine gas and carbon monoxide.

Abstract: A resetable shut off valve includes a body (10) having an inlet (12) and an outlet (14). The inlet and outlet are connected in the valve body through a fluid passage which includes an opening (26). A movable plunger assembly (42) includes a seal disc (56) sized for blocking the opening. The plunger assembly is biased towards a position blocking the opening by a compression spring (57). A u-shaped wire spring (66) includes a foot portion (70) which engages a recess (46) in the plunger assembly to hold the assembly disposed from the opening. The foot portion of the wire spring abuts a first surface (36) in the body. The wire spring is attached at the end opposed of the foot portion to a movable pressure plate (58) which abuts a diaphragm (80). When fluid pressure is introduced to a second chamber of the valve (78) above the diaphragm, the wire spring is pushed against the first surface, deforms and disengages the recess in the plunger assembly.

Abstract: A solenoid valve of the hung diaphragm type includes a diaphragm assembly having a pilot valve seat mounted for movement toward and away from a main valve seat in a valve body, a plunger assembly consisting of a valve disc holder reciprocably mounted in the pole piece of the electromagnetic valve resiliently supports a valve disc for cooperation with the pilot valve seat, being actuated by a plunger slideably mounted in an enclosure tube. The valve holder is biased to an upper position and a pickup extension spring is coupled between the valve holder and diaphragm valve assembly to lift the latter from the main valve seat. A necked down end of the valve holder prevents abrasion at the edge of the pole piece while a groove in the actuating face of the plunger prevents excessive distortion of the end of the pole piece due to repetitive impacts.

Abstract: A four-way fluid valve combines direct solenoid operation of one port with pilot valve operation of a second port and a common exhaust port, all of the ports being located in the valve body. Direct valve operation is achieved by a magnetically operated plunger carrying a normally closed valve element and operable to move a separate valve holder carrying a normally open valve element. A pilot operated valve disc is supported at the inlet port for axial movement to inlet or exhaust positions in response to inlet pressure or a pilot-operated piston.

Abstract: A solenoid valve assembly includes a valve body and an outwardly extending core tube assembly comprising a core tube, a fixed pole piece and a slidable plunger for actuating a valve in the valve body. An electromagnetic coil assembly comprising a flux frame and cylindrical coil is slidably and removably supported on the core tube and is secured in place by a contractible ring with a shoulder engaged in a groove in the outer end of the core tube. The ring is an injection molded plastic part and is split, having a tongue and socket interconnection with plural ratchet teeth thereon to provide adjustable constriction of the ring. A pair of integral spring fingers are provided on opposite sides of the ring to axially bias the coil assembly against the valve body.

Abstract: An arrangement which connects a pair of valve mounting manifold blocks in end-to-end abutment includes each block having an opening in oneend thereof, the respective end openings in the pair of blocks being in registry with one another when the respective ends of the pair of blocks are aligned and abut one another. A fastener extends from the opening in one block into the opening in the other block, and the opposite ends of the fastener are respectively fixed to the blocks such that the fastener is contained substantially entirely within the blocks. The openings may be defined by slots in the bottom of each block and the fastener may be a screw extending within the slots in threaded engagement with a nut.
