Title: Hydraulic bicycle rim brake
Inventor: ROTTENKOLBER LUDWIG
IPC: F16D55/228
Filed: 1984-09-26
Granted: 1987-08-27
Abstract: The invention relates to a hydraulic rim brake for bicycles with a triggering mechanism which is attached to the handlebar of the bicycle and is actuated by a hand lever, with two brake cylinder housings which are attached to the frame of the bicycle in oppositely located relationship to each other and enclose between them a wheel rim, the brake cylinder housings being connected by pressure lines to the triggering mechanism, with pistons displaceable in the brake cylinder housings, and with brake shoe supports arranged on these pistons for supporting brake shoes engaging the rim. In order to protect the piston from the effect of harmful bending moments, provision is made for the brake shoe supports to be in the form of flanges which are connected to the piston and are each displaceable parallel to the motion of the brake piston in a slide guide provided on the brake cylinder housing, and for the slide guide to simultaneously constitute abutments for absorption of the braking forces.

Title: Data capture window extension circuit
Inventor: AMBROSIUS WILLIAM III
IPC: G11B5/09
Filed: 1984-02-22
Granted: 1987-12-17
Abstract: A digital data capture window extension circuit utilizing a matched pair of signal detection subcircuits that are activated during alternate cycles of a master read clock. The interleaved operation of the paired subcircuits permits each subcircuit to detect and process an incoming data signal, resulting in an effective overall processing rate twice that of prior art circuitry. The invention therefore permits the reading of data at a high rate using a system clock of the same frequency as the incoming data.

Filed: 1985-06-24
Granted: 1988-09-29
Abstract: The invention relates to a hollow racket frame, e.g. for tennis, made by injection moulding of reinforced thermoplastics material. The frame has a head and handle portions and pairs of integrally-formed stringing holes (26, 27) are in the outer circumference (23) and are in the inner circumference (22) of the head respectively. Each stringing hole is defined by an integrally-moulded reinforcing tubular projection (24, 25) projecting inwardly of the hollow frame. The two opposed projections are of insufficient length to meet inside the hollow frame. The integrally-formed holes and tubular projections are made using suitably shaped mould pins (15) passing through holes in a fusible mould core (10) around which the thermoplastics material is injected. Pins (15) are a tight fit in their holes for the centrai portion of their lenght which provides positive location during moulding.
