Title: Automatic safety control for cinematograph and like machines
IPC: G03B21/18
Filed: 1919-07-05
Abstract: 150,867. Geyer, R. M. July 5, 1919. Addition to 132,293. Kinematograph apparatus.-The safety control apparatus according to the parent Specification is modified mechanically and electrically to make it more automatic in its operation, so that it can be controlled by the operation of a single lever; the safety shutter is also provided with two locking-devices, one adapted to be unlocked mechanically and the other electrically; and an audible warning is automatically given to indicate a departure from, or approach to, the normal speed of the machine. A lever 53, Fig. 17, which is adapted to be moved into any of the positions A, B, C, D, E operates the intermediate shutter through a three-armed lever, and also the safety shutter 20 through a lever 32, in a similar manner to that described in the parent Specification. The separately-operated switch 4 of that Specification is replaced by a switch at the lower end 155 of a three-armed lever 154, which is pivoted at 33 and is operated by the lever 53 through a cam-disk 198. The safety shutter 20 is mechanically unlocked through the lever 154, the upper end of which is pivoted to a link 164 having at the free end a slot 166, which works over a pin on a pawl 167 until the end of the slot engages the pin and frees the pawl from a tooth 163 on the safety shutter bar 26. The safety shutter is unlocked electrically by the operation of the lever 74, Fig. 2, of the parent Specification, which engages a transverse rod 150, Fig. 17, on a bellcrank lever 138, thus operating a lever 144, the notched upper end of which normally engages a pin 148 on the shutter bar 26. A switch 8, Fig. 40, which takes the place of the stopping-switch 8 of the parent Specification and is arranged either in the magnet circuit or the motor shunt circuit, is opened by the operation of the lever 53, through a three-armed lever actuated by a pin projecting from a cam 197. The lever which is operated by the energizing of the electro-magnet 10, as described in the parent Specification, is adapted, after the electro-magnet has been fully energized, to open a switch 309, Fig. 40, through lever mechanism, thus switching off lamps L<2>, L<3>, L<4>, of a lamp-resistance 11, in order to increase the resistance in the magnet circuit. The governorswitch 9 is operated by an arm on a rotary disk actuated by the governor; this arm is also adapted to close a switch in a buzzer circuit including a lamp L<5>, an audible warning being thus given when the speed of the machine is about to fall from, or rise to, a predetermined limit. Automatic means, comprising lever mechanism operated by a part of the cam disk 198, are provided for closing the switches 7, 12, after they have been held open, as described in the parent Specification, owing to the film failing to travel properly through the machine, such closing-means operateing when normal conditions have been restored and the machine is restarted.

Title: An improved method and means for atomizing and aerating liquids
IPC: B05B7/00
Filed: 1933-06-15
Abstract: 409,918. Injectors &c. STAINES, F., 94, Victoria Street, London. June 15, 1933, No. 17115. [Class 71.] Liquids are atomized and aerated simultaneously by causing a jet of the liquid to impinge on and displace a spherical body which normally seals the aperture through which the liquid passes, thereby permitting passage of the liquid, the sphere being freely mounted or supported, and the jet serv-. ing to induce a current of air or other gas which co-operates with the sphere in atomizing the liquid. The liquid may be used for lowering or raising the temperature of rooms or for washing glass or other hollow ware. In the form shown in Fig. 1, the spherical body 11 is mounted freely on a seating 9 and is displaced by a jet of water from a nozzle 1. The atomized liquid foams within a receptacle 7a which, together with an outer casing 13 through which air is drawn off by a pipe 13a, rests on a corrugated plate 14 in a trough 8. The nozzle 1 is located at the base of a cone-shaped body 7 to which air is admitted through perforations 3. By omitting the bodies 7<a> and 13, the device may be used for washing tumblers, which may be inverted over the atomized liquid. In the form shown in Fig. 2, the foaming liquid emerging through a perforated body 21 in a tube 23 overflows into a tray 22 having a perforated plate 20a disposed thereon on which articles to be washed may be supported. Liquid collecting in the tray 20 escapes by a pipe 16b to which the overflow pipe 16a for a chamber 15 containing the nozzle 1 immersed in water is connected. The nozzle 1 in this case is provided with side perforations 16 from which liquid flows into the chamber 15. Provision for admitting air by means of pipes 18 is also made. In an alternative form of valve, the upper part of the spherical body is recessed and engages a pin encircled by a spring, the other end of which engages a bridge piece, so that the body is only displaced against the action of the spring, and may be used in devices disposed in a horizontal as well as a vertical plane. The pin may be provided with vanes to effect a further breaking up of the liquid.

Abstract: 1,155,686. Washing machines. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 10 April, 1968, No. 17248/68. Heading D1A. A washing-machine, having an electrically driven agitator or pulsator mounted in a tub, comprises an electro-mechanical device with holding contacts 5 which with other circuits, e.g. that of the motor 9, is energized, when the heater thermostat 3 first cuts off the heater 2, and remains so even if the heater 2 is subsequently switched on and off again. In operation, the wash tub of the twin-tub washing machine is filled and the laundry placed therein, timer 8 and the thermostat are set. Switch 1 is turned to 12 o'clock to complete the circuit through thermostat switch 3 to heater 2 and lamp 14 and the water is heated. When the thermostat operates switch 3 to cut off the heater and extinguish light 14, relay 4 operates to close contacts 5 and at the same time timer 12 starts, wash motor 9 starts and the solenoid is operated which controls the clutch connecting the agitator or pulsator to motor 9. These circuits continue to be energized even if switch 3 reverts to heating position. When washing is complete, arm 7 having left strip 13, motor 12 and the solenoid are de-energized but motor 9 remains energized to operate the emptying pump. The laundry is then placed in the spinner and switch 10 is operated by closing the lid to energize spinner motor 11. The machine may be controlled manually by switching switch 1 to 3 o'clock and thereby cutting out relay 4.

Filed: 1938-06-10
Abstract: 515,839. Switching control of electricity supply. BRITISH THOMSON - HOUSTON CO., Ltd. June 10, 1938, No. 17303. Convention date, June 10, 1937. [Class 38 (iv)] An electric control system adapted more particularly for electric welding comprises a transformer 12 with a magnetic shunt 14 mounted adjustably adjacent thereto, the secondary winding 11 of the transformer being connected in the welding circuit, and the primary 10 being in series with an impedance 15 across the line 16, so that when the secondary circuit is closed by contacting the electrode 18 with the work 17 the resultant rise in voltage across the impedance 15 operates a relay 26 which closes pairs of contacts 23 and 33, thereby energizing an electromagnetic switch 19 with contacts 20 which short-circuit the impedance 15. Simultaneously, the voltage generated in a winding 29<1> upon the magnetic shunt 14 operates a relay 25 which closes pairs of contacts 22, 32 in parallel with the pairs 23, 33 whereby the energization of the winding 21 of the 'switch 19 is maintained after the short circuiting of relay 26 by contacts 20. The closure of contacts 33 of relay 26, and the subsequent closure of contacts 32 of relay 25, complete the circuit of a rectifier 31 in series with the winding 30 of a relay 27, this relay being of the time-delay type controlled by means such as a dashpot 34 so that its contacts 24 are closed instantaneously but open with a predetermined time interval. If, during welding, the arc is momentarily interrupted, the contacts 22 of relay 25 may be opened without de-energizing the winding of switch 19, which is maintained through the contacts 24 of relay 27.
