  • Patent number: 9162652
    Abstract: A shape-changing spray arch for a “touchless” spray washer for automotive vehicles and the like. A transit frame which can change shape is mounted in a fixed arch frame and connected to an actuator which changes the shape of the side and top spray conduits in a reciprocal fashion as vehicles pass through the arch. In addition, the spray conduits, both side and top conduits, can be twisted or reoriented around their respective longitudinal axes to be aimed more toward an approaching vehicle and then reoriented to be aimed more toward a receding vehicle, the change in angular orientation being effected as the vehicle passes through the arch. These features can be used separately or in combination.

  • Patent number: 9052001
    Abstract: An epicycloid planet gear cam that converts rotational movement of a driveshaft into linear movement of an output device is disclosed. An epicycloid planet gear is assembled inside a stationary housing with an internal stationary ring gear. A driveshaft eccentric is connected to a driveshaft. The driveshaft eccentric rotates freely in a mounting hole of the epicycloid planet gear. When the driveshaft rotates, the driveshaft eccentric engages the epicycloid planet gear against the stationary ring gear and causes the epicycloid planet gear to rotate. A cam follower pin attached to an output device is held against a cam track of the epicycloid planet gear. As the epicycloid planet gear rotates, the raised cam track height or the slotted cam track distance from the center of the epicycloid planet gear causes the cam follower pin to move up, down, in, or out thereby moving the output device.

  • Patent number: 8534240
    Abstract: An improvement to the Waissi type opposed piston internal combustion (IC) engine is proposed. The engine has at least one pair of aligned and opposed cylinders with one reciprocating double-headed piston assembly in each cylinder pair. The reciprocating motion of the piston is transmitted to the driveshaft by a rotating crankdisk, which is off-centered mounted to the driveshaft. The high friction metal to metal contact between the crankdisk and the piston contact wall is replaced by a combination of a roll resistance and friction under hydrodynamic conditions resulting to a significantly reduced total resistance between the piston and the crankdisk. This is accomplished by utilizing a bearing ring assembly slidably installed on the annular perimeter surface of the crankdisk. When the crankdisk rotates the bearing ring is held in its designed place in a slot bounded laterally only by the connecting members of the integrated double-headed piston assembly.

  • Patent number: 8418572
    Abstract: A three-dimensional cam mechanism capable of selecting a cam guide surface shape freely to improve the degree of freedom for selecting a target locus on the follower side, transmitting power between orthogonal axes and performing a reversible operation. A three-dimensional cam guide surface (2 (3)) is formed in a cam (1), and the cam guide surface (2) is caused to guide a cam follower (6 (7)) formed at a predetermined angle at one end of a follower side link (4), so that the rotational movement of the cam (1) is translated into the swinging movement at the other end of the follower side link (4). Thus, smooth operations of the cam are obtained by the selection of the shape of a supporting member and by the free design of the cam guide surface shape, without being limited to the power transmission between the orthogonal axes or followed by backlash.

  • Publication number: 20080148885
    Abstract: A brake/differential lock pedal linkage includes a two-stage manual control that may lock a differential before progressively engaging a brake. The manual control may be a foot pedal or hand lever. The linkage may include a brake cam lever that pivots on a brake cam shaft in response to movement of the manual control, a differential lock link connected between the brake cam lever and an actuator that can move a differential lock shaft to lock the differential, and a lost motion coupling between the brake cam lever and the actuator allowing the brake cam lever to pivot to a differential lock position in which the actuator moves the differential lock shaft sufficiently to lock the differential, before the brake cam lever pivots further to progressively engage the brake.

  • Patent number: 7258202
    Abstract: The invention provides an elevator having a car movable along guide rails mounted in a shaft. The elevator comprises an inspection control station mounted on top of the car and accessible via a movable control station cover, blocking means for selectively preventing movement of the car into a safety space within the shaft and actuation means for actuating the blocking means. The actuation means is configured for concurrent movement with the control station cover. Accordingly, a temporary safety space is automatically created within the shaft as the maintenance technician opens the control station cover to move the car using the inspection control station.

  • Patent number: 6837198
    Abstract: The invention proposes a variable valve train (1) for throttle-free load control of an internal combustion engine. Each cylinder of the internal combustion engine is provided with two inlet valves (9). According to the invention, each inlet valve (9) cooperates with a particular adjusting element (8, 8a), and the adjusting elements (8, 8a) can be actuated independently of each another. This additionally enhances the variability of the valve train.
