Title: Improvements in or relating to electric control devices
IPC: G01R11/60
Filed: 1960-07-14
Abstract: 905,052. Control of several motors; controllers. LANDIS & GYR A.G. July 14, 1960 [July 17, 1959], No. 24604/60. Class 38 (3). A control shaft 17, forming part of a maximum demand meter, is driven by a servomotor 3 through one revolution at a time. During each revolution, the shaft 17 changes over a switch 5 and returns it to its initial position, the shaft being coupled through reduction gearing 18 to a shaft 19 for actuating switch 6. The switch 5 may also be actuated manually by push-button 20, and a second servomotor, forming part of unit 2, may be associated with the first. When a switch 7 is actuated by a timer or remote control unit 23 to engage contact 13, both motors are energized through contacts 11, 9, and start together. A holding circuit is then completed through switch 5 which immediately engages contact 10. Switch 6 is subsequently engaged with contact 12 and remains in this position, for the rest of the cycle. At the end of the revolution of the control shaft 17, the switch 5 is re-engaged with contact 9 to de-energize the motor. The motor is re-started when a further control signal is applied to unit 23 so that switch 7 is re-engaged with contact 14. The push-buttons 20 afford separate control of one motor, without affecting the other. The switch 6 may comprise a rotatable contact-arm associated with semicircular contact segments. The control of the switch 5 is effected by a cam-plate of insulating material mounted loosely on shaft 17 and driven by a dog fixed to the shaft. The push-button has a thrust spring co-operating with an abutment surface on the cam-plate, Fig. 2 (not shown).

Title: A process for the production of planographic printing surfaces on metal
IPC: B41N3/08
Filed: 1932-09-07
Abstract: 407,047. Printing-surfaces etching. SCHLESINGER, A., 23, Spenerstrasse, Berlin. Sept. 7, 1932, No. 24970. [Class 100 (ii).] A process for the production of planographic printing-surfaces on zinc or other metal consists in first producing the design in any known manner, e.g. by transfer printing or photographically, in bare metal on the metal plate, the non-printing areas of the plate being covered, e.g. with gum or a chrome gum layer, then applying to the surface a mixture of drying and non-drying oils and resins dissolved in a volatile solvent and, after drying, and, if desired, repeating one or more times the application of the resin mixture, removing the gum &c. layer with the superposed resinous deposit. A suitable resinous mixture consists of 80 grammes of shellac, 30 grammes of boiled linseed oil, 30 grammes of castor oil, 600 c.c.s of ordinary industrial alcohol, 200 c.c.s of turpentine, 10 grammes of a siccative, 5 grammes of aniline, 10 grammes of mastic, and 100 grammes of xylene. In a modification, the whole or part of the drying oil may be replaced by shellac. When repeating the application of the resin mixture to the plate, successive applications may be differently coloured to enable the details of the design to be more easily observed. A coating of a black fatty ink may be finally applied. Before the application of the resin mixture the design may be etched into the plate by suitable acids or salts to which may be added a fatty oil, such as castor oil, and alcohol. The resin mixture may also be added to the etching agent so that the etching and the deposition of the first layer of the resin mixture may take place simultaneously.

Title: Improvements in or relating to apparatus for measuring the velocity of moving objects
IPC: G01P3/68
Filed: 1950-10-18
Abstract: 749,812. Electric indicating systems. BURROWS, H. Jan. 18, 1952 [Oct. 18, 1950], No. 25368/50. Class 40(1) [Also in Groups XIX and XL(a)] Apparatus measuring the velocity of a moving object comprises two frangible electric circuits interrupted by the passage of the object to successive initiate two beams of light which are projected on to a mirror for reflection on to a light sensitive screen; the mirror and screen being relatively movable at a predetermined speed by driving mechanism to produce an indication of successive light spots thereupon whose displacement is a measure of the time interval between the interruptions and of the velocity of the object. In Fig. 1, two frangible wires or screens 1a, 1b spaced a known distance apart along the track of a bullet are connected to earth from tapping points 5, 6 of potential dividers 7, 8 across the output of a H.T. supply unit 9. The taps are also connected to the control electrodes of xenon-filled discharge tubes 11, 12 whose anodes are connected to earth through condensers 14, 15 which may be charged from the H.T. supply through ganged switches 16, which are momentarily closed immediately before firing. The bullet then breaks the wires 1a, 1b in its path to successively trigger the discharge tubes, the flashes from which are focussed by lens systems 17, 18 on a constant speed rotating mirror 19 reflecting them as spots of light 22, 23 on the periphery of a calibrated transparent drurn 21 coated with a long-afterglow fluorescent screen. The displacement between the spots on the drum is a measure of the time taken by the bullet to traverse the distance between the wires 1a 1b and thus of its velocity. The wires may be connected in the H.T. supply to continuously glowing discharge tubes which are successively extinguished when the wires are broken. The screens may be replaced by stationary photographic films, and according to the Provisional Specification the rotary mirrors may be eliminated by traversing the films synchronously across the path of the received light beams.

Filed: 1971-04-19
Abstract: 1343441 Proximity switches KUREHA KAGAKU KOGYO KK 19 April 1971 [19 March 1970] 25450/71 Heading G1N [Also in Division H1] The channel conductance of a field-effect transistor is controlled by means of a gate potential derived from an electret in the gate circuit, variation of conductance being obtained by movement of the electret or by movement of another body relative to the electret. Fig. 5 shows a proximity switch in which the electret 1 is mounted in contact with a rear electrode 2 connected through a variable capacitance diode to the gate of the FET 5. A metal net 20 is spaced from the opposite face of the electret 1 and the approach of a body A of a grounded conductive or semi-conductive material or of a dielectric material is detected by the influence it has on the electrostatic capacitance between the electret 1 and the net 20, such influence being sensed by the FET 5 by way of the rear electrode 5. Fig. 7 shows part of a further proximity switch using A. C. operation, the electret in this case comprising a rotating disc having radial sectors covered by a grounded conductor 25, leaving sectors 26 exposed. The induction electrode 21 is stationary and comprises similar radial sectors so that an alternating voltage is induced therein by the rotating electret disc. The amplitude of the A. C. output is influenced by the approach of a body A as in the previous embodiment, and a tuned amplifier and phase detector are used to obtain a D.C. signal voltage which is applied to the gate electrode of an FET.
