Abstract: Disclosed is a self deployed, self retracting flotation device for a land hicle, the device including covers hinged to the sides of the vehicle. Inflatable air bags are attached to the covers so that inflating the bags swings up the covers and subsequently deflating the bags allows the covers to swing down. The device is constructed so that the bags protrude from between the cover and the vehicle when inflated and retract to a position between the cover and the vehicle when deflated. A reversible pump operable from within the vehicle is used to inflate or deflate the bags.

Abstract: A military range safety light signaling system used on combat vehicles of e type having a freely rotatable gun turret. The signaling system is comprised of a vertical column of lights, preferably three lights from top to bottom of red, amber, and green in a regular traffic light pattern and a rotating flashing light mounted on the left rear of the gun turret. The rotating flashing light is preferably an interchangable infrared beacon mounted high above the turret for use in live fire exercise or an amber light for use in highway movement of the combat vehicle. An operator inside the combat vehicle may selectively switch on any combination of the vertical column of lights and the rotating flashing light to represent the operating status of the vehicle weapons system and its movement.

Abstract: The invention is an assembly of a push-pull switch and a device to selectively limit the action of the push-pull switch. The switch has a body, a plunger translatable into or from the body, and a round head on the plunger. The switch opens or closes depending on whether the plunger is extended or retracted. The device is comprised of two semi-cylindrical sleeve halves that fit together to form a complete sleeve about the head of the plunger. The sleeve is open at both ends, has two internal grooves into which the head can snugly fit, and has an external groove to accommodate a clip, tie or like mechanism for holding the sleeve halves together. Depending on which internal groove is fit over the head and on which end of the sleeve faces the body of the switch, the plunger will either be locked in an extended position or will be prevented from resting in a retracted position.

Abstract: Disclosed is an emergency bypass mechanism to route fuel around an electrcally controlled fuel flow regulator of a combat vehicle when flow through the regulator becomes severely restricted. The mechanism includes electrically actuated valves hydraulically in parallel with the regulator, the valves being partly controlled by signals generated during manually shifting of the vehicle's transmission and partly controlled by a system of switches in a control panel.

Abstract: Disclosed is an apparatus for manually shifting an electronically control automated transmission. The device includes a series of mechanical linkage elements and gear transelements connected between the solenoid-operated valves of the automatic transmission and a control lever in the driver's compartment of the vehicle. One of the mechanical linkage elements is a cam shaft whose rotational position determines which subset of the solenoid operated valves will be actuated.
