Abstract: A torque transmission system has driving and driven pulley units around which an endless V-belt extends. Each pulley unit has a stationary pulley part rotatable with a shaft and a movable pulley part disposed to define with the stationary pulley part a circumferentially continuous groove for receiving the V-belt. The movable pulley parts of the pulley units are axially resiliently biased so that the radii of the circle along which the V-belt engages the driving and driven pulley units are varied to change the speed-change ratio of the transmission system. The movable pulley part of the driven pulley unit is axially shifted by the action of fly weights held between a stationary plate fixed to the shaft and a holder fixed to the movable pulley part.

Abstract: A regenerative pump apparatus has a housing and a substantially disc-shaped impeller rotatably housed by the housing. Circumferential rows of radial vane grooves are formed in the outer peripheral portions of both side surfaces of the impeller. Each circumferential row includes first vane grooves of an axial depth equal to or greater than a half of the impeller thickness and second vane grooves of an axial depth smaller than a half of the impeller thickness. The first and second vane grooves are arranged alternatingly in the circumferential direction in each row, such that the first vane grooves and the second vane grooves in one row are axially aligned with the second vane grooves and the first vane grooves in the other row.

Abstract: A device for preventing the vibration of a windshield wiper including a weight having two ends each secured to one of opposite ends of a pin extending through the end of a holder and separated from each other a suitable distance for the holder and the weight to move relative to each other between the two ends of the pin. The device is mounted on an auxiliary support member of a wiper blade for avoiding the wiper blade being separated from the surface of the windshield by the pressure of air when the vehicle travels at high speed.

Abstract: A torque transmission system has driving and driven pulley units drivingly connected by an endless V-belt. Each of the driving and driven pulley units includes a stationary pulley rotatable with a shaft and a movable pulley disposed to define with the stationary pulley a circumferential continuous groove for receiving the V-belt. The movable pulleys of the driving and driven pulley units are axially resiliently biased so that the radii of the circles along which the V-belt engages the driving and driven pulley units are varied to change the speed-change ratio of the transmission system. The movable pulley of the driven pulley unit is axially shifted by fly weights. The driving and driven pulley units are provided with cam mechanisms each comprising a cam member and a follower member. When the load on the driven pulley unit is suddenly varied, the cam mechanisms are operative to keep constant the rotational speed of the driven pulley unit irrespective of variations in the load on the driven pulley unit.

Abstract: A pressurized fluid-operated power transmission device, is typically shown being shaft driven from an automotive engine as the drive for the compressor of a cooler and a fan is provided with a centrifugal governor and valving for limiting output rotational speed of the power transmission device. In one embodiment a noise-preventing back-flow check valve is provided.

Abstract: A torque transmission belt means which is extended between a driving pulley and a driven pulley for transmitting a driving force from the driving pulley to the driven pulley.The torque transmission belt means comprises a plurality of ring-shaped metallic strips which are superimposed on each other, and two kinds of blocks which are arranged along the metallic strips so as to be shiftably engaged therewith.Only one kind of blocks are contacted with said pulleys and the other kind of blocks are bevelled on opposed surfaces facing to the direction of the movement so that they can tilt with respect to one kind of blocks when they are entrained around the pulleys.

Abstract: An exhaust-gas-recirculation system for use in diesel engines, having a valve member adapted to control the flow rate of the exhaust gas recirculated from the exhaust pipe to the intake pipe of the diesel engine. The exhaust-gas-recirculation system has a fly-weight rotatable in synchronization with the engine to produce a centrifugal force, a governor sleeve displaceable in response to a thrust thereon given by the fly-weight, a control spring counteracting the thrust on the governor sleeve and having a spring load changeable in response to the change in the amount of depression of an accelerator pedal, and an actuator operative in response to the displacement of the governor sleeve to actuate the valve member.

Abstract: A monolithic catalyst converter comprises a monolithic catalyst retaining catalyst metal, a cylindrical metallic container receiving the catalyst therein, a radial shock absorbing member disposed in a space between the catalyst and the container, an annular metallic plate disposed in each of axially end surfaces of the catalyst, a retaining member fixed to an inner wall of the container so as to be opposed to the annular metallic plate, an axial shock absorbing member disposed between the annular metallic plate and the retaining member and at least one annular sealing member composed of a compact body obtained by compressing metallic fine wire fabric or ceramic fibers, which is disposed in the space under pressure. By disposing the annular sealing member, unpurified exhaust gas is prevented from flowing out of the space.

Abstract: A device comprising exhaust leak preventing means made of a flexible material and mounted between a wall of a container and a catalyst element of a honeycomb structure disposed in the container to prevent leak of exhausts from an internal combustion engine mounted on a motor vehicle or the like through a gap between the container wall and the catalyst element before the exhausts are purified. Support means made of pliable metal may be used for holding the exhaust leak preventing means in place and keeping the latter from being dislodged from its position when the container is subjected to forces of impact or vibration.

Abstract: A catalyst-type exhaust gas purifying device utilizing a monolithic catalyzing element defining a plurality of exhaust gas passages therein. The catalyzing element is disposed within a cylindrical housing. Heat insulating spaces are provided by at least one circumferential row of bores disposed near the outer periphery of said catalyzing element and closed at the opposite ends.
