Patent number: 6036449Abstract: A system and method for air compressor control wherein the air compressor is loaded only when engine activities require it to be loaded or when free engine power is available to operate the compressor. An air compressor system is an engine-driven, piston-type compressor which operates in a loaded and an unloaded mode and provides air to a vehicle's air powered devices, such as service brakes, air suspension, windshield wipers, etc. The operating mode of the compressor is controlled by a pressure activated air governor which applies an air signal when pressure in a reservoir reaches a set level that activates a cap valve on an unloader stopping the air compressor. When the air pressure in the reservoir drops below a lower set pressure or when energy is "free," such as during downhill operations, the air governor exhausts the air signal allowing the air compressor to resume operation.Type: GrantFiled: March 24, 1998Date of Patent: March 14, 2000Assignee: Cummins Engine Company, Inc.Inventors: Dipchand V. Nishar, Thomas A. Dollmeyer, Christopher R. Nelson

Patent number: 6036174Abstract: For some powered drum winches, e.g. in sailing boats, it is desirable that the drum can be driven with two different speeds. Basically, this is no technical problem, but it has been difficult to achieve both a high efficiency and a simple construction. It has been proposed that with the use of a plural shaft gear an advantageous result is obtainable in making the gear drive the drum with two different speeds based on a reversible driving motor being driven in one or the opposite direction. This control principle is also used in the present connection in which, however, it is disclosed how the relevant gear can be designed in a compact and inexpensive manner about only a single gear shaft.Type: GrantFiled: August 26, 1998Date of Patent: March 14, 2000Assignee: Fr.

Patent number: 6035985Abstract: A flat belt 6 is wound around between an annular friction surface 2 at a periphery of a first rotatable member 1 and an arc-like friction surface 4 of a rocking portion 3 of a second rotatable member 5 which is relatively rotatably supported on the first rotatable member 2, and an initial tension is applied to the flat belt 6. With relative rotation movement between the rotatable members 1 and 5 in a locking or free direction, the rocking portion 3 is rocked around a rocking axis Q by the flat belt 6. By virtue of such rocking movement of the rocking portion 3, the tension of the flat belt 6 is increased up to a higher value than the initial tension or decreased down to a lower value than the initial tension. This permits connection or disconnection of the transmission of torque between the rotatable members 1 and 5 in dependence on the relative rotational direction of the rotatable members 1 and 5.Type: GrantFiled: July 8, 1998Date of Patent: March 14, 2000Assignee: Bando Chemical Industries, Ltd.Inventor: Hirofumi Miyata
