摘要:
An emergency oxygen system for use on aircraft in conjunction with an on-board primary oxygen supply system is designed to supply oxygen to aircraft personnel in the event that the on-board oxygen supply system fails. Additionally, if the aircraft personnel is forced to eject from the aircraft, the emergency oxygen system automatically activates to provide oxygen and simultaneously disengages all electrical connections from the aircraft frame. The system includes an emergency oxygen supply which is coupled to a differential pressure activated valve through an oxygen release valve, the oxygen release valve having the capability of being manually or automatically triggered. The on-board oxygen supply system is also coupled to the differential pressure activated valve and, depending upon the relative pressure between the on-board oxygen supply system and the emergency supply system, as sensed by the differential pressure activated valve, oxygen from one or the other is channeled from the differential pressure activated valve to a face mask or the like.

A fluid hose connector capable of resisting transverse forces to avoid inadvertent disconnection from a mating connector includes an elongated hollow body which includes a first portion that provides an extending collar to restrain the lateral movement of a mating connector and a second portion which provides for connection to a source of fluid. The body portion includes a hollow coupling for removably retaining a mating connector and a hollow plunger which is adapted to be slidably received within the coupling. The plunger is provided with a first disconnect position which prevents fluid flow through the body and a second position which permits fluid to flow therethrough. A spring disposed within the body urges the plunger to the first or disconnect position so that when the connector is not mated, it prevents fluid flow therethrough as well as providing a dust cover for the connector opening.

The kit of the present invention is for use in the refilling within a survival unit of a gaseous supply tank through a filler valve having a threaded stem adjacent the free end thereof and a gripping surface on the filler valve. The gas is generally oxygen although other gas may be supplied. The kit includes an adapter to provide coupling relationship with the threaded stem of the filler valve so as to permit a flow of oxygen into the supply tank such that refilling thereof may take place without removal of the supply tank from the survival kit. The adapter includes an elongated member with an aperture extending therethrough and is adapted to mate with the filler valve in sealing engagement therewith so as to permit gas flowing through the aperture to enter the filler valve. The adapter further includes a holder with a bore extending axially therethrough and the elongated member extends axially through the aperture. A gripping section is provided on the adapter so as to obtain a coupling to the threaded stem such that rotation of the holder by means of the gripping section obtains abutting sealing engagement between the member and the filler valve. A wrench adapted to be used in conjunction with the adapter is provided as part of the kit. The wrench includes a socket for enclosing the gripping surface to provide retention of the filler valve in fixed position as the member is releasably coupled to the filler valve.

A snap assembly adapted to receive a cooperating buckle element is disclosed in which a base is provided having oppositely disposed front and rear ends with upper and lower surfaces intermediate the ends, and a hook is integrally formed with the front end of the base and extending inwardly in the direction of the rear end and terminating in a distal end. The hook having an inner surface bounding one side of the hook facing the upper surface of the base for forming an enclosure for receiving the buckle element therein. A flexible locking member is adapted to be moved relative to the inner surface of the hook, with the locking member having an outer end and an oppositely disposed free end. The outer end formed by a wall having one surface thereof extending in overlapping relationship with and secured to the base. Resilient means for continuously urging the free end of the locking member into abutting pressural engagement with the inner surface of the hook and being movable toward and away from the inner surface is provided. The resilient means comprises a rib integrally joined by an arcuate configuration at one end thereof with the wall and extending upwardly therefrom, and a clip integrally joined by an arcuate configuration at one end thereof with the other end of the rib. The clip terminates in the free end of the locking member and is inclined upwardly relative to the base for movement relative thereto. The movement of the locking member provides an angle of deflection in the clip and in the rib so as to obtain a relatively large translation of the free end of the locking member while maintaining a relatively low stress concentration in the locking member by distribution of the stress in each of the arcuate configurations.

A container and method for compression packaging a compressible article which includes use of a container having two rigid sides each connected to the other at a first end establishing a spaced-apart, parallel, and substantially co-extensive relationship between the sides. The container also includes closure means at the other end of each side for releasably holding the sides in the relationship established by the first end against the face of the compressible article held therebetween, and retaining mean fixed along the sides of the container. The retaining means has an open condition which permits compression packaging of the article and a closed condition which retains the compressible article under pressure in the container until released by the closure means.
摘要:
A closure assembly useful as a means for sealing a pressurized package which includes clamping means shiftable between an open position to receive an open portion of the pressurized package and a closed position to substantially hermetically seal the open portion of the pressurized package. The assembly also includes a retaining means coupled to the clamped means and adapted to be actuated by a force substantially independent of the force associated with the pressurized package whereupon the actuating force will maintain the clamping means in the closed position. Another part of the present closure assembly is an actuation means which is engageable with the retaining means in a manner which supplies the force enabling the retaining means to keep the clamping means in the closed position.
