Title: Brake lining for disk brakes
Inventor: LEIDECKER HANS DIETER
IPC: F16D65/092
Filed: 1994-08-12
Abstract: A brake pad for disc brakes has guides (22, 23) projecting laterally from its back-plate (20) with supporting surfaces (25, 26, 27) on which the brake pad (1, 2) is guided to move axially and supported in the brake. The peripheral forces arising during braking are borne in traction partly via the guide (22, 23) in the leading section of the brake disc and in compression partly via the guide (22, 23) in the trailing section of the brake disc. To prevent the brake pad (1, 2) from falling out of the brake if the supporting surfaces (25, 26, 27) slide off the relevant guide surfaces (12, 13, 14, 15, 16, 17) of the brake, especially because of increasing wear on the pad facing (21), the brake pad (1, 2) has additional safety lugs (30) which are arranged radially outside the edge (5) of the brake disc and project beyond the faces (25) of the guides (22, 23) along the secant (11).

Filed: 1981-12-28
Abstract: PCT No. PCT/CH82/00128 Sec. 371 Date Aug. 16, 1983 Sec. 102(e) Date Aug. 16, 1983 PCT Filed Dec. 3, 1982 PCT Pub. No. WO83/02340 PCT Pub. Date Jul. 7, 1983.The liquid crystal display cell (21) indicates the date in an aperture situated at 12 o'clock. The hour wheel (31) and the center wheel (29) present coaxial pipes which pass through the dial and bear hour and minute hands. These wheels are driven by a wheel-train (30, 28, 27) actuated by the stepping motor (25) which receives its pulses from the circuit (23) controlled at a frequency of 1 Hz for example by the quartz (48). The 24-hour wheel (33) bears a contact element (46) which, once per revolution, grounds the terminal (47). The pulse which results therefrom is transmitted to a counter incorporated in the circuit (23). This counter controls the decoding circuit which controls the display cell (21). To effect the setting of the date, the stem (35) is brought into its intermediate position (II). The contact element (40) borne by the yoke (38) then grounds the terminal (41), which causes in the circuit (23) the emission of pulses at a frequency of 1 Hz which controls a repeated and rapid change of date.
