A manual release apparatus attachable to a fifth wheel of a truck cab for disengaging a king pin on a truck trailer from the fifth wheel, including an elongated, rigid lever arm, a first end of which is pivotally attached to a side of the fifth wheel at a location spaced from the opening through which the release rod extends, a second end of which is spaced away from the fifth wheel extending horizontally from the first end, whereby the lever arm is attached to the release rod, such that a manual movement of the second end of the lever arm will cause the lever arm to be pivoted horizontally about the first end, thereby causing the release rod to be pulled outwardly to disengage the king pin from the fifth wheel.

The New Design for Crutches and Sitting Device is an improvement of the basic crutch to provide needed support to ameliorate potential injuries and improve ambulation for persons suffering from injured lower limbs, lumbar region or other injuries and who frequently required using crutches for mobility. However, crutches require more energy from the user than merely walking, and frequently, a crutch user may require rest. Prior crutch systems have not provided a convenient way to provide the user with such rest. The current invention fulfills two functions: (i) providing improved walking aid for those recovering from orthopedic surgery of the spine and lower extremities—as well as those who suffer from permanent disability from the spine and lower limbs; and (ii) improved sitting aid for those recovering from orthopedic surgery of the spine and lower extremities—as well as those who suffer from permanent disability of the spine and lower limbs.

An automobile safety glass breaker tool is held against an automobile safety glass window and fired to break the window. The tool is armed by sliding a firing pin piston to the rear against a spring and fired by releasing the firing pin piston. The firing pin piston hits a 22 blank cartridge to fire the blank cartridge. The blank cartridge drives a striker piston forward, and a striker point on the striker piston impacts and shatters the automobile safety glass window. The striker point is limited to reach about 0.6 inches forward and out of the tool to prevent injury to a user.

An apparatus for moving parked aircraft with an omni-directional tractor via an aircraft lift dolly that is revolvably coupled thereto which includes a hinged gate to entrap the aircraft nose gear. The aircraft lift dolly may be removably detachably coupled to the omni-directional tractor or may be integral to it through two attachment points via attachment members. The aircraft lift dolly includes a lift mechanism having a lift carriage which is selectively elevated. The lift carriage includes a fixed forward chock and a rear chock that it repositioned longitudinally with respect to the forward chock and is hingedly coupled. The chocks are positioned about the aircraft nose gear without movement of the aircraft. Elevating the lift cradle elevates the chocks and the nose gear cradled therebetween.

A pressure relief valve integrally formed with a section of conduit in a closed system for pumping cementitious material eliminates any dead space in the system within which the cementitious material may flow and set, and thus avoids system disassembly for cleaning following use and the possible replacement of clogged system components. The pressure relief valve includes a hollow cylindrical housing disposed on a conduit. First and second elongated linear slots are aligned with the cylindrical housing's longitudinal axis and are disposed in opposed portions of housing, with one slot in flow communication with the conduit. A cylindrical drum having a third elongated linear slot disposed within the cylindrical housing is freely rotatable therein. A handle attached to one end of the drum allows for manual rotation of the drum for aligning the three slots permitting the discharge of cementitious material and release of pressure in the system.
