Title: Improvements in the electrical ringing of bells
IPC: G10K1/34
Filed: 1945-10-08
Abstract: 600,972. Bell ringing mechanism. ALLMANNA SVENSKA ELEKTRISKA AKTIEBOLAGET. Oct. 8, 1945, No. 26137. Convention date, Nov. 28, 1944. [Class 13] [Also in Group XXXVII] Bells are rung electrically by a three-phase motor coupled to the bell, a controlling switch dependent for its action upon the speed and direction of rotation of the motor being coupled to the motor shaft by means of an electrical slip coupling. In one construction a motor 2 is provided with a controlling contactor 4. On operation of a starting switch 6 the contactor starts the motor and a relay 5 operates and locks up. The motor is then started and stopped while the switch 6 is closed by movement of spring 15 which makes and breaks contact 13 under the action of a finger 16 mounted on a spring retained stator of an eddy current coupling connected with the motor shaft. In this arrangement the bell is driven during one stroke and returns by gravity in the reverse stroke. By using a similar but reversed circuit in connection with contact 10 the bell can be driven during each stroke. Modifications are described in which opening the switch 6 makes operative a circuit including a slow release relay which reverses the motor to brake the swing of the bell for a fixed time period. Also in another arrangement a further .slow release relay alters the motor connections from three phase to single phase after a fixed running time.

Title: Improvements in and relating to electrical switches operated by leakage current
IPC: H01H71/24
Filed: 1936-09-26
Abstract: 482,297. Protective cut-out systems ; electromagnetic relays; automatic circuitbreakers. OSBORN, H. J., and OSBORN & SHARP, Ltd., H. J. Sept. 26, 1936, No. 26185. [Class 38 (v)] In a cut-out switch controlled by a relay operated by leakage current occurring between an apparatus 5 to be protected and an earth or neutral conductor n, the leakage current energizes an electromagnet which, on the potential of the apparatus reaching a predetermined value, actuates a switch to send a current from the mains through the same or a second electromagnet which operates the main switch to disconnect the apparatus from the circuit. In the arrangement shown in Figs. 1 and 3, a winding 3 on the centre limb of a threelimbed core 1 is connected between the apparatus 5 and the neutral n. When the leakage current exceeds the predetermined value, a light relay armature 7 is attracted and connects a portion 3<1> of the winding between the phase and neutral conductor p, n ; the core then attracts an armature 15 to open the main switch at the contacts 13, 14. The contacts 13 are carried by the armature and are normally held in engagement with the contacts 14 by springs 16 on pins 17 which form guides for the ends of the armature. When the armature is attracted it is held in the raised position by a spring stop 18 to prevent reclosure of the circuit until the stop is released by hand. The winding 31 may be separate from the winding 3 and may be mounted on another limb of the core or on a separate core. In a modification, Fig. 5, the contact 14 of the main switch is carried by a spring blade 12 and is normally held in engagement with the fixed contact 13 by an overset toggle 21, 22, which is adapted to be broken by an extension 25 of the armature 15 when the latter is attracted by the energization of the portion 3<1> of the winding 3. In place of the toggle, the contacts 13, 14 may be held in engagement by an arm, which is pushed out of engagement with the arm 12 by the extension 25 of the armature when the latter is attracted.

Abstract: 423,377. Control of A.C. motors. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Seeley, H. T. ; 512, Orchard Avenue, Yeadon, Lansdowne P.O., Pennsylvania, U.S.A.) Sept. 22, 1933, No. 26192. Convention date, Sept. 22, 1932. [Class 38 (iii)] A load-responsive relay 6, which effects a predetermined increase of the excitation of a synchronous motor 1 at a predetermined load value, is supplied with a compensating current which causes it to pick-up and dropout at substantially the same value of load. The compensating current is supplied from a transformer 15 through an impedance 14 of suitable value. At the predetermined load value the relay 6 closes its upper contacts 8 and energizes a relay 5 which cuts out resistance 3 from the motor field circuit. A selfmaintaining relay 9 is also energized and maintains the relay 5. When the load falls slightly below the predetermined value, the relay 6 drops out and de-energizes the relay 9 which de-energizes the relay 5 to restore the field to its normal value.
