Title: A new or improved electric motor
IPC: G04C5/00
Filed: 1947-08-26
Abstract: 632,264. Electric clocks. HORSTMANN CLIFFORD MAGNETICS, Ltd., HORSTMANN, F. O., and CLIFFORD, C. F. Aug. 26, 1947, Nos. 23550 and 27144. [Class 139] [Also in Group XXXV] The movement of a clock is driven by an electric motor which, if desired in association with a spring drive, may serve to maintain synchronism of a rotary member e.g. in a clock and which comprises an oscillating member such as a reed or pendulum magnetically coupled to a rotary member and one of these members has a wavy magnetic track adapted to guide and be guided by the other member during relative movement. As shown in Fig. 1 an iron yoke 4 attached to a magnet core 5 has an A.C. magnetising coil 6 and an air gap between pole pieces 7. A reed 8 carries a magnet 9 the upper portion of which lies in the air gap so that these parts vibrate at the frequency of the A.C. A tuning collar 10 mounted on magnet 9 may adjust the resonant frequency. The magnet 9 has two pole pieces 12 lying close to the periphery of a rotor 13 carrying a wavy magnetic path 14. The distance between pole pieces 12 is equal to a whole multiple of the pitch of the wave 14. A hand operated starting device 15, 16, 17, 18 is provided. When the rotor 13 is set in motion the pole pieces 12 follow the track 14 driving it synchronously with the A.C. supply with sufficient torque to drive the gear train of a clock. To obtain a small energy consumption the coil 6 may be connected in series with a condenser or the winding on coil 6 may consist of two insulated metal foil strips the opposite ends of which form the terminals. The device may be driven electrostatically (Fig. 9 not shown). In a D.C. arrangement the reed operates a trembler contact in the coil circuit. To avoid reduction of the magnetic coupling with increasing amplitude of oscillation the crests of the track waves may be laterally extended as shown in Fig. 6. Fig. 7 shows a plastic disc with magnetic pins 23 and a vibrating reed carrying a magnet. The edge of the rotor projects into the gap between the poles of this magnet. Each magnet pole carries a wavy magnetic track with extensions as described. Two or more oscillating members may cooperate in the drive. Fig. 10 shows a shading coil 32 causing a phase displacement of one of two drives which are correspondingly phase-displaced with regard to the wave track. Three phase displaced oscillating members may be driven by the phases of a 3-phase supply. Specification 596,216 is referred to in the first Provisional Specification.

Title: Improvements in electro-magnetic switches for remote control
IPC: H01H29/18
Filed: 1940-08-16
Abstract: 536,761. Mercury switches; electromagnetic switches. DAWSON, W. J., and METROPOLITAN ELECTRIC SUPPLY CO., Ltd. Aug. 16, 1940, No. 23608/39. [Class 38 (v)] A solenoid 6 is energized continuously at constant voltage, an intentional increase or decrease of 'the applied voltage causing it to attract or release an armature. As shown, the armature is an iron sleeve 20 surrounding a closed-bottomed tube 19 apertured at 22 and freely movable in a mercury container 17, the normal liquid level of which is shown at 18. Electrode 26 enters with clearance a hole, in the top of 19 without touching the mercury. When the voltage is increased adequately, the sleeve 20, tube 19, and mercury therein, are drawn downwards. The mercurylevel in the tube 19, thus falls so that mercury creeps through operture 22 into the tube 19 which continues to descend while the voltageincrease persists, so raising the mercury into contact with electrode 26. With a sustained and sufficient voltage-reduction the buoyancy of the tube and armature restores them to their original position. For adjustment purposes the container 17 is fastened frictionally by a rubber washer 32 to a sleeve 31 rotatable on a further sleeve on the solenoid, the sleeve 31 having notches 35 engaged by a retaining spring finger 34. A plug-in resistance 8 in series with the solenoid for the higher voltage ranges may be replaced by a solid link for lower voltages. The device may be moved on and off by the last 2 per cent. of the permissible plus and minus 6 per cent. voltage-variation, and may be used for controlling street-lighting.

Filed: 1945-09-13
Abstract: 598,935. Telemotor systems. GRIFFITH, R. C. Sept. 13, 1945, No. 23623. [Class 69 (ii)] In a hydraulically operated remote control System comprising a master cylinder 10 and a slave cylinder 90, each containing a reciprocable piston and liquid lines connecting the chambers on both sides of the master piston with the chambers on both sides of the slave piston, means are provided for compensating for changes in volume of the hydraulic liquid which comprise a master piston 24 fixedly attached to a rod 14 on which floating pistons 32, 34 are slidably mounted to form spaces 30 on each side of said master piston, and the sliding pistons are urged towards each other to apply a predetermined equal pressure to both the hydraulic circuits. Attached to cylinder 10 is a spring 50 fastened at one end to a stubshaft 58 to which is fixed a brake drum 60 and a pinion 62. The pinion engages teeth on members 64, 66 which carry bifurcated arms 70 and 74 respectively straddling the piston-rod 14 and engaging the floating pistons 32, 34. The spring 50 causes the pistons 32, 34 to be urged towards each other, and due to the rack- and-pinion mechanism these pistons are actuated equally and simultaneously in opposite directions whenever the volumetric displacement of the liquid changes. The piston-rod 14 is connected to an operating lever 18 to which is attached a rod 22 carrying a brake band 80 surrounding the brake drum 60 so that whenever the lever 18 is actuated the brake is engaged thereby preventing movement of the rack-andpinion mechanism and the floating pistons, these pistons being free again to compensate for volumetric changes immediately the lever 18 is released on completion of the required movement of the master and slave pistons. In a modified embodiment, the floating pistons are urged towards each other by hydraulic liquid displaced by fixed pistons secured to the racks and disposed in a separate cylinder attached to, and in communication with, the master cylinder. In another modification, the brake mechanism is replaced by an electrical control of valves governing the communication between the separate and master cylinders.
