Abstract: An emergency vehicle includes an extendable ladder and a compartment for storing a kit containing a source of light and a cable. When the vehicle arrives at the scene of an emergency, the ladder is partially extended, and the kit is removed from the compartment. The source of light is then suspended from the ladder, near the distal end of the ladder, and the cable is connected between the source of light and a source of power. The ladder is then extended and elevated. The method provides light in hard-to-reach places, regardless of whether the accident scene already is lighted. The kit preferably includes cable support hangers which aid in suspending the cable along the length of the ladder. When the emergency work is complete, the components of the kit may be removed and stored in the vehicle. In another embodiment, the kit includes a unitary frame which holds a generator and a plurality of lamps. The kit does not interfere with the operation of the vehicle, and substantially extends its capability.

Abstract: The invention is a high-power portable cutting tool which is particularly effective in cutting through sheet metal. The tool can thus be used for extricating accident victims from wreckage. The tool is operated by hydraulic power, and has one movable blade and one stationary blade. The movable blade is curved, and is mounted so as to close onto the stationary blade. The curvature of the movable blade is such that its initial contact with the stationary blade occurs at its free end. The stationary blade is formed on an anvil, anchored within the frame of the tool. The anvil is sufficiently long that its end extends beyond the end of the movable blade. The anvil is anchored within a slot formed in the cover portion of the frame, and is locked into position with a dowel. The mounting of the anvil within the slot is such that the forces exerted on the blade are directed against the heavy cover, and not against the dowel.

Abstract: A system is shown for automatically applying the brakes of a vehicle moving in reverse, when there is an obstruction in the path of the vehicle. Obstructions are detected by an ultrasonic sensing device which operates a valve, which causes the brakes to be applied. In one embodiment for use with hydraulic brakes, a dual accumulator utilizes both power-steering fluid and braking fluid in the operation of the system, without mixing the two fluids. In another embodiment, the system is used with a pneumatic braking system. In both embodiments, the system is activated only when the vehicle is in reverse gear. In still another embodiment, for use with hydraulic brakes, the brakes are applied solely by pressure from the power steering system of the vehicle.

Abstract: The invention comprises a hydraulic rescue tool which is useful in extricating victims form traffic accidents. The tool can perform three basic functions: pushing, pulling, and cutting. The tool comprises a pair of pivotably mounted arms connected to each other within a common yoke. The arms are forced together or apart by a hydraulically operated piston. Attached to the arms are a pair of cutting blades. The arms are made of a graphite laminate composite material for increased strength.
