Title: Improved brake operating mechanism
IPC: F16D65/14
Filed: 1960-09-12
Abstract: 914,157. Pneumatic brakes. BENDIXWESTINGHOUSE AUTOMOTIVE AIR BRAKE CO. Sept. 12, 1960 [Sept. 11, 1959], No. 31389/60. Class 103 (1). Brake safety-mechanism comprises a chamber 55 which automatically contacts to mechanically apply a brake when the pressure of compressed-air supplied to the chamber from a reservoir 61 falls below a specified value. In the position shown with the brakes applied, air is supplied to a brake actuator 20 through a relay valve 60 to move a diaphragm 27 outwardly and hence actuate a brake rod 19. If the pressure in the system falls, a spring 46 in the assembly 21 pushes outwardly a diaphragm 50 which, through a push-rod 35 and a head 36, actuates the brake rod 19, the head uncovering bleed orifices 39 so that the pressure in chamber 55 does not rise. When the supply pressure is normal, depression of the usual foot pedal 70 causes the diaphragm 50 to be pushed back to the position shown. The assembly 21 and actuator 20 may be separate and the diaphragm 50 may have a rod attached to it from the other side to create a pull on a linkage when the pressure falls. Fig. 8 shows such an arrangement with a slave safety device 176 controlled by a master safety device 158.

Abstract: 1384618 Ratchet mechanism BULOVA WATCH CO Inc 5 July 1972 [8 July 1971 28 Jan 1972] 31555/72 Heading F2Q [Also in Division G3] In an electric timepiece, such as a clock, which is driven by a tuning fork 10, at least one V- shaped indexing element 16 is attached by its ends to the fork tines 10A, 10B so that a tongue 16A is reciprocated at right angles to the direction of tine oscillation and advances an index wheel 17. The wheel 17 is moulded integrally with a worm 18 and is mounted on tapered pivots 19, 20. The pivot 20 is carried on a resilient arm 21 and the resulting friction prevents rearward rotation of the wheel 17 during indexing.  The tine amplitude necessary to produce advancement of the index wheel, and consequently the driving battery voltage, can be halved by the use of two indexing elements (16<SP>1</SP>, 16<SP>11</SP>, Figs. 8-13, not shown), which are oppositely oriented and act alternately on the index wheel. The ends of the tines 10A, 10B are U-shaped and carry coil and magnet assemblies 14, 15 respectively. The coil assembly comprises drive and sensing coils 42, 43 wound on a former 40 and connected in a transistor circuit (Fig. 2, not shown).
