Abstract: An AC/DC power supply and platform for a military radio has been developed. The apparatus includes a base that supports at least one SINCGARS RT-1523 radio. The base is connected to an AC power supply and at least one DC power supply. The AC supply and DC power supply are configured to switch automatically to the DC power supply should the AC power supply fail.

Abstract: An artificial manually positionable elbow joint for use in an upper extremity, above-elbow, prosthetic which provides a locking feature that is easily controlled by the wearer. The instant elbow joint is very strong and durable to withstand the repeated heavy loadings encountered by a wearer who works in an industrial, construction, farming or similar environment. The elbow joint of the present invention comprises a turntable, a frame, a forearm and a locking assembly. The frame generally includes a housing for the locking assembly and two protruding ears. The forearm includes an elongated beam having a cup-shaped cylindrical member at one end and a locking wheel having a plurality of holes along a circular arc on its other end with a central bore for pivotal attachment to the protruding ears of the frame.

Abstract: A rigid patch body for placing over and around a damaged portion (hole) of the external wall of a pressurized vessel, such as a space vehicle or habitat. The rigid patch body allows a person such as an astronaut to make temporary repairs to the pressurized vessel from the exterior of the vessel to enable more permanent repairs to be made from the interior of the vessel. The pressure wall patch of the present invention includes a floor surrounded by four side members. Each side member includes a threaded screw for anchoring the patch body to the external wall of the pressurized vessel and a recess in its lower surface for supporting an inflatable bladder for surrounding the damaged portion (hole) of the external wall to seal the area surrounding the damaged portion to allow the vessel to be repressurized. The floor of the rigid patch body supports a source of gas in communication with a gas supply valve and a gas supply gauge in communication with the gas supply valve and the inflatable bladder.

Abstract: An articulated tang in clevis joint for incorporation in newly manufactured conventional strap-on orthotic knee devices or for replacing such joints in conventional strap-on orthotic knee devices. The instant tang in clevis joint allows the user the freedom to extend and bend the knee normally when no load (weight) is applied to the knee and to automatically lock the knee when the user transfers weight (load) to the knee, thus preventing a damaged knee from bending uncontrollably when weight (load) is applied to the knee.The tang in clevis joint of the present invention includes first and second clevis plates, a tang assembly and a spacer plate sandwiched and secured between the clevis plates. Each clevis plate includes a bevelled serrated upper section. A bevelled shoe is secured to the tang in close proximity to the bevelled serrated upper section of the clevis plates.

Abstract: A double face sealing device for mounting between two surfaces to provide an airtight and fluid-tight seal between a closure member bearing one of the surfaces and a structure or housing bearing the other surface which extends around the opening or hatchway to be closed. The double face sealing device includes a plurality of sections or segments mounted to one of the surfaces, each having a main body portion, a pair of outwardly extending and diverging, cantilever, spring arms, and a pair of inwardly extending and diverging, cantilever, spring arms, an elastomeric cover on the distal, free, ends of the outwardly extending and diverging spring arms, and an elastomeric cover on the distal, free, ends of the inwardly extending and diverging spring arms. The double face sealing device has application or use in all environments requiring a seal, but is particularly useful to seal openings or hatchways between compartments of spacecraft or aircraft.
