A system for recovering oil spilled on a body of water includes a buoyant containment boom of sufficient length to surround at least a portion of the spilled oil, the boom having a plurality of outer pipe sections, each outer pipe section being longitudinally perforated along one side that may be positioned against the spilled oil, a plurality of spaced-apart support members positioned within the outer pipe, and an inner pipe that is longitudinally perforated along one side, generally coextensive with the outer pipe, and rotatably positioned within said support members so that the perforations in the inner pipe sections may be positioned at a desired height within the outer pipe sections. The system also includes at least first and second suction pumps, the first pump acting to draw a water and oil mixture into the outer pipe, and the second pump acting to draw a mixture having a high percentage of oil into said inner pipe. Water is extracted from the mixture and the oil is stored.

A suspension system for a bed or bunk which is to rest on a substantially horizontally oriented deck and is particularly adapted for the sleeper compartments of large truck cabs and which substantially reduce the amplitude of vibrations and other disruptive movements of the truck. The system includes a lower support frame which is adapted to be on the deck. An upper support frame for supporting a mattress is positioned above the lower support frame. The two frames are interconnected by at least two torsion spring members wherein the upper support frame is free to move up and down relative to the lower support frame under the influence of the spring action of the torsion spring members. The spring action dampens the transmission of up and down movements from the truck to the upper support frame and the mattress positioned thereon.

An engine retarder brake for operating a valve in the combustion chamber of an internal combustion engine near the end of the exhaust stroke to thereby discharge compressed air and cause the engine to operate as a brake for the vehicle.

A variable timing apparatus, for an internal combustion engine equipped with a mechanical fuel injection pump, includes a tubular extender having a front flange bolted to the normal injection pump mount and a rear mounting flange bolted to the injector pump. The timing drive shaft is equipped with a male right-hand helically-splined drive. The injection pump drive is equipped with a left-hand helically-splined drive. A spring-biased, slidable coupler has a front end right-hand helically-splined socket that engages the male right-hand drive, and a rear end left-hand helically-splined socket that engages the male left-hand drive on the injector pump. After engine startup, oil pressure moves the sliding coupler axially rearward and rotates clockwise with respect to and as seen from the timing drive shaft. The injection pump drive also rotates clockwise, with respect to the coupler, thereby advancing injection timing.

A variable timing apparatus, for an internal combustion diesel engine equipped with a conventional mechanical fuel injection pump, includes a tubular extender having a front flange bolted to the normal injection pump mount and a rear mounting flange bolted to the injector pump. The tubular extender houses a timing drive shaft has a first end directly coupled to the engine's timing drive and a second free end equipped with a plurality of helical splines. The injection pump drive is equipped with straight splines. A spring-biased, slidable coupler, having a front end equipped with helical splines and a rear end equipped with straight splines, couples the timing drive shaft to the injection pump drive. After engine startup, oil pressure moves the sliding coupler axially rearward approximately 1.0 cm. As the slidable coupler travels axially rearward, it rotates and advances the injection timing by approximately 25 degrees.
