Assignee:

Avon Protection Systems, Inc. - Cadillac MI

International Classification:

A61M 11/00

US Classification:

12820227, 12820528

Abstract:

A self-contained breathing apparatus (SCBA) comprising: a mouthpiece; a breathing component; and a safety quick disconnect comprising: a valve body; a valve spool comprising an L-shaped channel formed such that when the valve spool is appropriately rotated, the L-shaped channel (i) places an opening of the valve body in communication with a first port, or (ii) places the opening in communication with a second port; and a lock mechanism for (i) preventing the valve spool from rotating unless the breathing component is positioned in one of first and second mounts formed on the valve body adjacent the first and second ports, and a replacement breathing component is positioned in the other of the first and second mounts, and (ii) preventing the removal of a breathing component from a mount adjacent to a port which is in communication with the opening.

Filed:

Jun 26, 2002

Appl. No.:

10/180774

Inventors:

Paul Chambers - Wayland MA, US

International Classification:

C06C005/06

US Classification:

102/275110

Abstract:

A plunger assembly includes an outer elongated housing having an open end, an electric match having an electrical initiator and an explosive material, disposed in the housing. A plunger is disposed in and is moveable in the housing. A coupling device is provided for connecting the outer housing open end to a selected plunger receiver which is adapted to actuate a selected event. Application of an electrical charge to the initiator activates the explosive material to produce gas in the outer housing, which drives the plunger through the outer housing and into impact with the plunger receiver to actuate the selected event. In a preferred embodiment, the plunger assembly is a firing pin assembly and the plunger receiver is an explosive primer assembly.
