Abstract: Arrangement for disc brakes having so-called floating suspension containing a brake disc and a brake caliper which is movably mounted on a caliper holder for axial motions relative to the brake disc. The brake caliper has at least one pair of brake pads having friction linings intended to be brought to bear against braking surfaces on the brake disc. Load-bearing supporting surfaces hold the brake pads normally in their intended positions in the caliper by absorbing the forces acting mainly on the brake pads due to friction against the brake disc by cooperating with edge surfaces on the brake pads. These supporting surfaces extend over only a part of the space up to the brake disc to an imaginary geometrical delimiting plane for each brake pad, said plane extending parallel to the brake disc. The brake pads have protrusions, each of which extend into an opening in the caliper or caliper holder, one opening being provided for each protrusion.

Abstract: The flexure stage disclosed herein is useful in aligning a semiconductor wafer during microlithographic exposure to define circuit elements on the surface of the wafer. The stage is a unitary structure which permits essentially lossless small angle relative rotation of a central portion of the stage with respect to an outer, annular portion of the stage. Three pairs of slots define three links extending radially with respect to the axis of rotation and, radially outwardly from each pair of slots, a respective transverse slot in the outer portion provides radial compliance for the outer end of the respective link.

Abstract: An adjusting device is disclosed for the brake shoes of inside shoe brakes. The adjusting device includes two levers which are articulated on a carrier at a lateral distance from one another. The levers each engage on one of two adjacent brake shoe ends and are jointly in engagement with a frustoconical endpiece of an actuating member guided rotatably on the carrier in a threaded bore provided between the levers and extending in parallel with a brake drum axis. During the rotation of the actuating member for the adjustment of the brake shoes, the two levers are pivoted in directions opposite to one another, being supported respectively on one of two mutually opposite edges of the brake-shoe webs so as to surround these. The adjusting device is merely attached by its levers on to the brake shoe webs so it can also execute self-reinforcing floating movements of the brake shoes in dual servo-brakes.
