Two motors are arranged on opposing sides of a common shaft, drive plates of the pump / motors being rigidly coupled to each other, for example by being in hard contact with opposing sides of the shaft. By providing hard contact between the pump / motor drive plates and a common shaft, the drive plates and shaft act as a substantially solid element under compression, thereby substantially canceling axial loads generated by the pump / motors directly through the shaft. Residual axial loads are handled via bearings positioned on the shaft adjacent the drive plates in such a manner that the drive plates are in light contact only with the bearings. As a result, friction experienced by the bearings is substantially reduced as compared to conventional systems, thereby improving the efficiency of the system. To further reduce loads on the bearings, the pump / motors are arranged to ensure that they generate radial forces in a direction that is opposite to that of a separation force generated by a torque transferring device carried on the shaft and transmitted to the bearings. A common housing surrounding the two pump / motors, bearings and torque transferring device is divided into three regions, to segregate the bearings and torque transferring assembly from the pump / motors. In this manner, the regions containing the pump / motors are substantially filled with oil to, for example, fully lubricate the pump / motors, while the central region containing the gears and torque transferring device contains a significantly smaller volume of oil to simply splash lubricate the contents of the region, thereby reducing drag on the bearings. Control means are provided for selectively moving the two pump / motors substantially simultaneously to a selected displacement angle, using mechanical systems alone and in combination with hydraulic systems.

A patient lifting apparatus is provided that attaches to a bed frame having a plurality of legs and a headboard. The apparatus includes an upright member, a boom mechanically associated with the upright member, an upper support bar that extends across the bed frame and secures the upright member to each side of the headboard, and a lower support bar that extends across the bed frame and secures the upright member to the legs. The upright member is supported for rotation about a vertical axis by upper and lower bearings on the upper and lower support bars, respectively. A telescoping foot member extends from the lower support bar and is movable between a stored position and an extended position for stabilizing the lifting apparatus. A support arm extends from a lower end of the upright member and rotates along with the upright member to transfer vertical forces into the floor.

An actuating device for an active control suspension system which is provided at both ends of a sub-frame of a vehicle body and connected to one end of an assist link having the other end mounted at a knuckle and which changes a position of a mounting point of the assist link at the vehicle body, may include a member bracket fixedly mounted at each end of the sub-frame, provided with openings formed at both sides and an upper surface thereof, and formed of a pair of slide grooves having arc shape at the both ends thereof to slidably receive a pair of slide plates therein; an actuator connected to both slide plates through a pin-bolt unit; and a cam-bolt unit assembling a bush of the assist link with both slide plates and setting an initial position of the mounting point of the assist link at the vehicle body.

A textile sleeve and method of construction thereof is provided. The sleeve includes a braided, tubular wall extending lengthwise along a central longitudinal axis between opposite ends. The wall has a decreased length, increased cross-sectional area first state and an increased length, decreased cross-sectional area second state. Heat-set, yarns within the wall impart a bias on the wall, wherein the bias causes the wall to remain in each of the first and second states absent an externally applied force.

A flange mounted weatherseal includes a carrier and a flexible cover covering the carrier. The carrier includes a base portion, a first side portion and a second side portion generally parallel to the first side portion and cooperating together with the first side portion and the base portion to define a generally U-shaped channel. The first side portion defines a plurality of first fingers, the second side portion defines a plurality of second fingers opposite the first fingers along a longitudinal axis, and the base portion defines a plurality of webs offset along the longitudinal axis relative to the first fingers and the second fingers. The first fingers, the second fingers and the webs each include deformations defining a non-planar cross sectional shape along the longitudinal axis to increase the rigidity of the carrier.

An integrated brake component mounting bracket for a mechanical spring axle / suspension system of a heavy-duty vehicle includes an axle seat that is disposed on and is rigidly connected to an axle of the vehicle. An air chamber mounting bracket is rigidly connected to the axle seat, and a cam shaft assembly mounting bracket is rigidly connected to the axle seat. A brake air chamber of a brake system is attached to the air chamber mounting bracket, and a cam shaft assembly of the brake system is mounted to the cam shaft assembly mounting bracket. The integrated brake component mounting bracket thus provides mounting of the brake air chamber and the cam shaft assembly on the axle seat, which reduces the number of components that are welded to the axle and enables the use of a thinner-wall axle, desirably reducing the weight and cost associated with the axle / suspension system.

A convertible roof system uses composite roof rail(s). The composite roof rail can have portions that are made of differing materials.
