Abstract: A semi-passive cooling system for an armored vehicle includes an intermittent pressure source, an accumulator for storing pressurized fluid from the intermittent source, and a mechanism to control the pressure in the accumulator. The system also includes a water reservoir and automatic controls for stabilizing pressure in the reservoir at a level lower than the accumulator's pressure. A sheet of water-absorbent, wicking skin on an exterior zone of the vehicle receives pressurized water from the reservoir in response to signals from a heat sensor at the exterior zone. The sensors signals open a valve in a supply line connected between the reservoir and the sheet, the valve remaining open for a predetermined interval.

Abstract: Disclosed is a sleeve for modify a seat belt assembly, the sleeve being used to vary the position of the shoulder strap or other portion of the assembly relative to the passenger. The sleeve is installed at a portion of the seat belt assembly where a belt or strap forms a loop through an eye mounted at an anchor point of the assembly, and the sleeve holds opposed sections of the loop in facial contact. The sleeve has flaps that fold and attach together so as to releasably secure the sleeve around the loop sections. The sleeve also has a tongue extending therefrom through the eye and into attachment to one of the flaps, whereby movement of the sleeve relative to the seat belt assembly is limited or prevented.

Abstract: The invention is a free standing engine tester that can be fabricated of el stock and vehicle parts available in forward military areas where it is used. The tester has a vehicle transmission and "final drive" power take off units mounted to a frame, and the final drive units contain braking mechanisms by which a load can be applied to the engine. The engine and transmission are mounted on a frame whose configuration and low center of gravity prevent engine torque from tipping the tester. A winch mounted to the frame has a hand operated crank by which a person using the tester can sufficiently tension a brake actuation cable engaged to the braking mechanisms so that a stall load can be applied to the engine.

Abstract: The invention is a camouflage system for the exterior of a military vehicle. The system includes a set of photoreactive lenses on the vehicle, the lenses having an irregular topography and a thin anti-reflection film on the faces of the lenses. The system reduces or eliminates contrast between illuminated and shadowed panels of the vehicle so that the vehicle more thoroughly blends into the background against which the vehicle is viewed.

Abstract: The invention is a rig useful in preventing relative movement between two hicles or other payloads suspended from a helicopter. The rig has two triangular plates which are in connection between the vehicles, the connection being loose before cables from the helicopter to the triangular plates are tensioned. When the helicopter rises, tension on the cables raises the triangular plates, thereby pivoting clevises which are engaged with the triangular plates and which are mounted on on the vehicles. The pivoting of the clevises draws the vehicles into tight abutment with abutment plates at the ends of the triangular plates so that the vehicles act as a single, more stable load. A cross member is connected both between the triangular plates and between the vehicles to inhibit relative lateral movement of the vehicles.
