Title: Clock or watch having an electric switch controlled by the movement
IPC: G04C23/10
Filed: 1961-04-07
Abstract: 917,191. Time switches. EBAUCHES S.A. April 7, 1961 [April 8, 1960], No. 12504/61. Class 38 (5). A spring-urged pivoted contact 22 controlled by a clock-driven cam has its co-operating contact 26 positioned by a manually-operable cam such that the contacts are (1) always in engagement, (2) never in engagement, or (3) engaged under clock control. An electric clock movement (not shown) rotates a cam 4a by friction with an hour cannon pinion (Fig. 3, not shown) and thereby operates a follower member 20 pivoted at 21 and carrying a contact 22. Spring 23 urges member 20 towards cam 4a as shown. A co-operating contact 26 is mounted on a strip 24 urged by its own resiliency against an insulating cam 27 which has three positions selected manually by a knob on the clock face (Fig. 1, not shown), and located by spring blade 30 co-operating with flats 29a, 29b and 29c on part of cam 27. As shown, the cam 4a causes the contact 22 to make and break with contact 26 at times selected by a second knob on the clock face (Fig. 1, not shown) which rotates cam 4a via gears 8, 7 and 5; gear 5 having a frictional drive on cam 4a which is greater than that between cam 4a and the hour cannon pinion. When cam 27 is turned to the position where surface 32 engages strip 24 the contact 26 is urged into continuous engagement with contact 22 irrespective of the position of cam 4a. When surface 33 of cam 27 is brought against strip 24 the contact 26 is allowed to move so far away from contact 22 that engagement between them cannot occur.

Abstract: 201,995. Bright, F. E. May 3, 1922. Lathes; chucks.-An automatic chucking lathe having one or more tool-holders movable transversely to the lathe axis has a tool slide adapted to reciprocate parallel to the lathe axis and also to rock transversely to this axis, the rocking movement being produced by the transversely sliding tool-holder. The lathe comprises a frame in which is mounted a hollow spindle 11 containing an axially-movable plunger having inclined grooves 5<f>, Fig. 9, for actuating the jaws of the chuck 5. which slide in radial slots and are adapted for internally gripping the work such as a ring A. The spindle is driven from cone pulleys on a shaft 14 ,and worm gear 12, the pulleys being connected to the shaft through a clutch 18, handoperated by a lever 18a and disengaged after a cycle of operations has been completed by a pivoted trigger 61 on a cam 55. The cam shaft 31 is driven from the spindle through worm gears 43, 32 and a shaft 34, mounted in a bracket 37 which is capable of being swung about the axis of the cam shaft and is yieldingly held to the frame by bolts 38, 39 and arcuate slots so that.the worm drive will become disengaged if excessive pressure is put on the tools. A hand-wheel 65 is provided on the shaft 34 for moving the tools when the worm drive is disengaged. The adjustable connection of the bracket also allows the gear ratio of the cam-shaft drive to be changed. A tool 10 for turning the periphery of the work is mounted in a holder 45 carried by a bar 44, which is longitudinally slidable by means of a cam 55, lever 58, and adjustable collars 60. Two other tool-holders 7a, 8<a> are adjustably mounted on a transverse slide 6, reciprocated by a lever 24 and cam 30, the slide also carrying a cam 47 which supports an arm 46 on the tool-holder 45 in two positions, the portion 47<a> presenting the tool 10 in a cutting position and the portion 47b lifting the tool clear of the work. In operation, the driving connections, which are also described in Specification 202,249, are so timed that the slide 6 moves to the right in Fig. 1 and a roughing-tool 7 acts on an end face of the work while the tool 10 is traversed by the cam 55. On reversal of the slide, a finishing-tool 8 acts in place of the tool 7, and the cam 47 lifts the tool 10, which is then withdrawn. Additional roughing and finishing tools such as 7<x>, Fig. 2, may be provided on the slide for machining the rear face of the work, and the tools may be changed so as to perform such operations as roughing, grooving, champering, finishing, &c. either singly or collectively. The work may be gripped externally and a boring-tool substituted for the tool 10.

Title: Power supply distribution and control system
IPC: H03K17/725
Filed: 1975-03-05
Abstract: 1467974 Touch or proximity switching systems TEXAS INSTRUMENTS Ltd 5 March 1975 [21 March 1974] 12670/74 Heading G1N [Also in Division H2] In a supply distribution and control system in which a semi-conductor switching device 6 is connected to control the supply of power to a load 4 such as a lamp, heater or cooker, the switching device 6 is rendered conductive or non-conductive in response to a low voltage signal isolated from the supply by a proximity or touch responsive switch. When conductive pad 29 is touched or approached by an operator's finger the body capacitance effectively connected across the gate of FET 24 causes the latter to become non-conductive and SCR 17 to be triggered so that current flows through relay winding RLA to close contacts RLA-1. Triac 6 is thus rendered conductive and the positive and negative half cycles of the supply across terminals 1-2 are applied to load 4. As a result of the conduction of thyristor 17 a negative pulse is applied via capacitors 20, 21 to thyristors 15, 16 to turn them off if they are conducting. If DIM pad 27 is touched thyristor 16 is rendered conducting and relay RLB energized so that contacts RLB1 are closed, the triac 6 only conducting during negative half cycles of the supply. When OFF pad 25 is touched thyristor 15 conducts but not thyristors 16, 17 so that triac 6 is not gated on, and the load remains unenergized. An LED 31 is also energized to enable the pads to be located. In addition to the switches 14 a two state switch 33 may be connected in the circuit in parallel with the switches 14. The pads 25, 27, 29 may be covered with a thin insulating layer or include a conductive ring surrounding the pad to provide a resistive operation. A single FET may be provided and its connection to the two state trigger circuit such that successive resistive or capacitive charges at a single conductive pad connected to the FET gate cause the supply to be switched on and off successively. Details of a supply system in a house are schematically described, Figs. 2, 3 (not shown).
