Rotational couplers for use with surgical devices that are actuated by semi-flexible actuators such as wires and the like. The couplers enable the actuators to apply various actuation motions to actuation features on the surgical device as well as other actuators to apply axial and rotational motions to the surgical device to manipulate the device into various orientations relative to an elongate shaft to which the device is movably attached.

A one way isolator for high torque devices, such as alternator-starters, driven by a flexible drive means includes a hub and a sheave each of which includes at least one stop member. The hub and sheave are linked by a isolating spring and, via a bearing and / or bushing, can rotate with respect to each other to provide isolation, through the spring, from torque variations when torque is transferred from the flexible drive means to the device. When substantial amounts of torque are transferred from the device to the flexible drive means, the sheave rotates with respect to the hub to bring the stop members into contact such that the isolator then acts like a solid pulley to facilitate the transfer of the torque from the device.

A composition for cleaning bearings in rotating equipment and industrial machinery that contains powdered limestone having a high calcium content dispersed in a calcium sulfonate grease, together with a colorant that readily enables a user to differentiate between contaminated grease, cleaning composition and fresh grease. A method is also disclosed that enables a user to clean and re-lubricate bearings without the need for removing the bearings from service or for shutting down the associated equipment or machinery.

A lift and operating angle varying mechanism is arranged to vary an intake valve operation angle and an intake valve lift of the engine continuously by rotating a control shaft with an actuator disposed at an end of the control shaft which is rotatably supported by a plurality of bearings. A lubricating oil is supplied to the bearings so as to reduce nonuniformity in temperature distribution of the control shaft in the longitudinal direction.

The present invention relates, generally, to the reduction or elimination of permanent and catastrophic herniations in Bowden cables or coil pipes in articulating devices or snake-like robots. More particularly, the present invention relates managing the coil pipes in a spiral pattern along the articulating device or snake-like robot to reduce or eliminate the necessity of the Bowden cables or coil pipes to slide along the length of the articulating device or snake-like robot. Reduction or elimination of the necessity for the Bowden cables or coil pipes to slide reduces or eliminates catastrophic herniations in articulating devices or snake-like robots undergoing one or more articulations.

An all terrain vehicle comprises a frame supported by at least a left wheel and a right wheel. The left wheel and the right wheel being connected to said frame by a left suspension and a right suspension respectively. The independently suspended wheels preferably are drive wheels. The wheels are driven by an engine through a transmission. The transmission is connected to the left wheel by a left half shaft and to the right wheel by a right half shaft. Constant velocity couplings are used to coupling the half shafts to the respective wheels and to the transmission. The constant velocity couplings connecting the two half shafts to the transmission are joined in a single housing. The housing includes a body portion and a gear portion. The two portions can be integrally formed. A left cage and a right cage are mounted within a left axial bore and a right axial bore formed in the body portion. The cages are secured for rotation with the body portion but can move axially within the respective bores. The two half shafts similarly are secured for rotation with the cages. The half shafts can be connected to the cages with respective inner members. The two bores can be combined or separated by a dividing wall.

An isolating decoupler comprising a hub, a one-way clutch engaged with the hub, a pulley rotationally engaged with the hub, a spring operationally engaged between the one-way clutch and the pulley, and an inertia member engaged with the hub through an elastomeric member, the inertia member substantially disposed within a width of the pulley, the inertia member moveable independently of the pulley.

A dispenser selectively mixes one or more chemical fluids into a motive fluid such as water by using diverting motive fluid to one or more channels formed in an eductor body, at least one of the channels being an eductor. When the motive fluid passes through the eductor, a selected chemical fluid is eductively drawn into the venturi of the eductor, producing a mixed fluid having a desired total flow rate and dilution ratio. Additional dilution ratios, flow rates, and chemical fluids are selectable by diverting motive fluid to another channel or combinations of channels. Carry-over of chemical fluid between dispensing is avoided by diverting the motive fluid rather than by diverting the concentrated chemical fluid.

A saddle ride type all-terrain vehicle includes left and right front wheels supported independently of each other on a vehicle body such that driving power is transmitted to said front wheels by way of a pair of left and right drive shafts extending from a driving source side. The vehicle also includes universal couplings provided at opposite end portions of each of the drive shafts, covered by rubber boots. The vehicle further includes a protector for covering the rubber boots.
