Abstract: A semiconductor wafer holding assembly that secures a semiconductor wafer for wafer handling by a semiconductor processing machine. The wafer holding assembly includes a clamp ring that is mounted to a support frame and that has a wafer-engaging surface. A plurality of latch assemblies are mounted about the periphery of the clamp ring and adjacent to the wafer-engaging surface. Each latch assembly includes a latch body that carries a clamping roller assembly and a supporting roller assembly. A rolling element of the supporting roller assembly rolls along a circular path on an inclined surface on the clamp ring as the latch body is rotated through a pivot arc between an unlatched position and a latched position. Unless the latch body is positioned in the latched position, the rolling engagement between the supporting roller assembly and the inclined surface suspends the rolling element of the clamping roller assembly above the wafer surface until the latch body is in the latched position.

Abstract: A latch for securing a wafer to a clamp plate. The latch may include a bearing that couples a wheel to a horizontal shaft. The horizontal shaft is adapted to rotate relative to the clamp ring so that the wheel secures the wafer. The bearing minimizes the amount of particles generated by the moving components of the latch that may contaminant the wafer.

Abstract: A clamp for gripping an elongate member comprises a mounting block having locating structures defining a desired position for the elongate member. Primary and secondary clamping yokes are each movable relative to the mounting block between a closed position, in which the clamping yoke engages an elongate member in the desired position, and an open position. A latch retains the primary clamping yoke in the closed position, and a force-transfer arm is effective between the primary clamping yoke and the secondary clamping yoke for retaining the secondary clamping yoke in its closed position when the primary clamping yoke is in its closed position.

Abstract: In conjunction with a cycle trailer having a frame the front reach of which consists of rounded tubing or bar, a universal-joint hitch consisting essentially of two diametrically opposed wafer-like sector bearings each of which contains on its face multiple diametrally disposed sector channels, in order to render easy the assembly of the trailer to one such sector channel in the bearings. The bearings include trunnions and integral annular thrust surfaces on their opposite faces. Through the thrust surfaces, the bearings are constrained to bear on the rounded tubing or bar of the frame from opposite directions by clamping and mounting arrangements which may include a hinge on one side of the bearings and a hand nut on the opposite side. This hand nut, when employed, is restrained from unwanted loosening by contrived interference or engagement, most conveniently through glancing interference of protrusions of its handle with the trunnion of one sector bearing.

The members have confronting surfaces which in the closed position retain the cable portions in side-by-side relation when disposed lengthwise between the members. The confronting surfaces of the members have opposed recesses which in the closed position firmly grip the clamps so that the clamps may be tightened by means of a wrench or similar tightening device.

Abstract: A process and an apparatus for forming an air gap pipe are provided. Inner and outer pipes are bent or deformed into comparable configurations such that the inner pipe can be mounted within the outer pipe. The outer pipe then is split longitudinally by a preprogrammed cutting apparatus. The cutting of the outer pipe terminates just short of the complete longitudinal length of the pipe to facilitate rematching later in the process. The cutter includes a follower to trace the actual configuration of the pipe and thereby to offset differences from one pipe to the next. An array of clamps are provided to align the outer pipe halves relative to one another and to facilitate the reattachment.

Abstract: The invention relates to a frame for the transport and storage of pipes of profile frame parts, of which the upper and lower profile frame parts are connectable with one another by rods which can be conducted through recesses of the profile frame parts and are swingably arranged with an end provided with a transverse piece in lateral transverse bores of a profile frame part. In order to improve the support of the pipes on the frame parts and to simplify and cheapen the manufacture, the frame parts are C-profiles with retracted base part, two C-profiles arranged in one another in opposite directions, the shanks of the outer C-profile extending beyond the base of the inner C-profile, or box profiles with side wall extensions. In particular, as middle frame parts there are used double C-profiles. In the free shanks or extensions of the profiles there are formed, as supports for the tube, divided-circular recesses, which, if need be, have a flange with inner reinforcing walls which faces inward or outward.

Abstract: A compact traction device includes a housing and a plurality of constant tension spring units disposed within the housing. Each constant tension spring unit includes a cable which extends from the unit through an opening in the housing. As the cable is pulled out from the housing, a substantially constant tension is developed on the cable. Hook elements are coupled to the end of each cable to enable attaching the cable to a ring or other connecting structure which, in turn, would be attached to some part of the body of a person utilizing the traction device. A brake device is included in the housing for each constant tension spring unit to inhibit the rapid retraction into the housing of the cables when the cables are released. A clamp is mounted on the exterior of the housing to enable attaching the traction device to a support frame. The clamp allows positioning of the device to have almost any orientation.
