Abstract: 1,099,459. Date and time printing apparatus. S. C. CAUSER. Dec. 22, 1964 [Dec. 23, 1963], No. 50722/63. Heading B6D. [Also in Divisions F2 and G3] Mechanism for the display or printing of the time of day and of the day or date comprises three rotary discs 21, 32, 45 which are advanced quickly at intervals of 1 minute, 1 hour and 1 day respectively, and remain stationary between the movements of advance. An input shaft 11 is driven at 1 r.p.m. The shaft carries a worm 13 having a cam 15 of the same helix angle as the worm and spring-urged toward a fixed cam 16. Worm-wheel 19 in mesh with the worm 13 advances the minutes disc 21 on shaft 20. The worm 13 performs an idling stroke against spring 17 owing to cam 15; once each revolution the cam releases the worm which moves longitudinally to advance the wormwheel. Worm 13 also meshes with a worm-wheel 22 on shaft 23 which carries a second sliding 24 having a cam 27 and functioning similarly to advance the hours disc 32 through worm-wheel 30 on sleeve 31. This sleeve carries a bevel gear 33 meshing with bevel gear 34 on shaft 35 which carries a spur gear 36 meshing with spur gear 37 on shaft 38. This shaft carries a third sliding worm 39 with cam 40 which as before advances a day disc 45 through worm-wheel 43 on sleeve 44. Worm 39 also drives a worm-wheel 46 on a shaft 47 which constitutes an output for driving ancillary equipment.

Filed: 1976-12-17
Abstract: 1535766 Displacement transducers UNIVERSITY COLLEGE CARDIFF 17 Dec 1976 [20 Dec 1975] 52258/75 Headings G1A and G1N A displacement transducer comprises a spring strip 20 fixed at one end to a block 19 with the other end resting on the surface of a four-lobe cam 16 mounted on a spindle 14 together with a wheel 15. A body whose displacement is to be measured rotates the wheel 15 and thus the cam 16 to produce sequential flexing of the spring strip, which is sensed by strain gauges 22 bonded to its surface and connected in a bridge network. The number of output cycles from the bridge provides a coarse displacement signal, and the amplitude of the signal in each cycle provides a fine displacement signal. The lobes on the cam may be sensed by a proximity detector. In another arrangement the displacement of the wheel 15 is sensed by a disc rotating in synchronism with wheel 15 to vary the optical, electric, or magnetic coupling between two parts of a transducer, one part of which may be a Hall plate or magnetosensitive element.

Title: Method of operating an electrochromic display device
IPC: G02F1/163
Filed: 1975-12-30
Abstract: A display panel having electrodes which define display points or symbols to be represented is filled with an electrochromic substance which visibly changes its optical properties under the action of an electric field. Drive circuits selectively deliver current pulses to selected electrodes in order to trip visible changes in the substance. For this purpose, the novel operating method uses, in a time-division multiplex mode, a sequence, interrupted by recovery pulses, of short current pulses of an intensity that is lower than usual to date. Because disturbing saturation effects now no longer occur, the total time for the display is nevertheless shortened.

Switching devices 2 mounted on the needle beds of a parallel machine, when affected by shock waves, cause the drive to the carriage 13 to be disconnected except when the carriage passes beyond monitoring points 17 at the ends of the needle beds, so that devices 2 are not affected by the extra vibration at the ends of the traverse. Device 2 comprises a sphere 5 which on excess vibration rolls away from the needle bed and engages contact plate 6. To allow for stronger shock waves sphere 5 may rest on an adjustable slope so that the shock necessary to move it can be varied. The disengaging arrangement for the drive to the carriage is as described in Specification 1362488. A switching device Fig. 10 to respond to shock waves in opposite directions has a sphere 5 lying between two upwardly sloping tracks 20, 21 each having an associated contact 6. In a further arrangement a sphere carried on a flat spring may be made to bounce off the needle bed by a shock wave and engage an adjustable contact. In a further arrangement, a sphere rolls away from the needle bed to break a circuit momentarily.
