Title: Timesetting arrangement for electrical timepieces
IPC: G04C9/08
Filed: 1976-02-23
Abstract: 1512351 Electronic watches SOC SUISSE POUR L'INDUSTRIE HORLOGERE MANAGEMENT SERVICES SA 1 Feb 1977 [23 Feb 1976] 07023/76 Heading G3T An electronic timepiece has setting circuitry controlled by a single manual switch 6 via a flipflop 7 and a sequential discriminator 5 so that by appropriate operation of the switch the user can (i) advance the seconds part of the time display in steps; (ii) stop the advance of the display; and (iii) advance the display at a higher than normal rate. As shown, actuation of the switch produces a Q output from the flip-flop. This output is fed to an adder 8, which also receives a 1 Hz output from frequency divider 3, and is thus passed as an additional pulse to advance the display 4 by a (one second) unit. The Q output also initiates counting in a chain 10 of five binary counters the first of which receives an 8 Hz signal. If the switch 6 is held closed, after 600 ms NAND gate 11 changes the state of a memory M3 whereby the last three stages of divider 3 are reset and the adder 8 blocked, arresting the display. If the switch is still held closed, after 3s a further NAND gate 12 flips a memory M1. Release of the switch followed by rapid reclosure will then, by means of memory M2 and the application of the Q output to NAND gate 16, produce a signal at that gate's output to close NAND gate 18, blocking the 1 Hz pulses from divider 3, and open gate 15 to feed 32 Hz pulses to the display for rapid advance. The display uses a stepping motor to drive hands, but application to digital displays of LCD or LED type is envisaged; a display may also be provided to guide the user through the setting steps. The switch is closed by depression of a stem which may, in a further position, allow correction of a date ring and of an hour hand only, as in Specification No. 1434443.

Abstract: 300,449. Turner, E. G. March 12, 1928. Kinematograph apparatus.- In apparatus in which air &c. is forced through orifices or jets on to the film in the gate, and a cut-off shutter operates when the air pressure fails, the cutoff shutter is held by a catch or detent which, when the air pressure fails, is released by a piston, diaphragm, or the like. As shown, air from, a blower enters a chamber 10 by a pipe 9 and passes through a conduit 11 to a hollow frame 6 having perforations 7 permitting it to escape on to the rear surface of the film in the gate. Air may also, or alternatively, pass through a pipe 26 to a nozzle 24 directing it on to the front of the film. A guillotine shutter 15, spaced from the frame 6 by a pyramidal casing 17, is held above the projection beam by the engagement of a notch 15<a> with the pointed end of an arm 19 which is pivoted at 20 and is connected by a link 21 to a piston 12'in the chamber 10. A spring 13, the pressure of which is variable by a screw 14, urges the piston over the end 11<a> of the conduit 11 when the air pressure fails, and thus rocks the arm 19 to release the shutter. The arm 19 may have a projection 23 which engages the notch 15a, when the shutter has fallen, and prevents the shutter from being raised until the air pressure is again restored. The arm 19 may be enclosed by a plate 16, carrying the guides for the shutter, so that it may not be operated by hand. The frame 6 may be replaced by a nozzle on the end of the conduit 11 which is arranged to spread the air over the film in one or more jets.
