Abstract: 821,580. Dictating-machines. ELECTRIC & MUSICAL INDUSTRIES Ltd. April 14, 1958 [April 13, 1957], No. 12123/57. Class 40 (2). A dictating machine backspacing mechanism in which the backspacing movement is stopped when the transducer reaches the point where the dictated passage began. The mechanism is for use with a disc record machine in which the inward traverse of the transducer is produced by a spirally grooved guide disc in the centre of the turntable, engaged by a toothed wheel which is rotated by an electromagnet to achieve backspacing which is initiated by closing a switch 6 in circuit with a relay 8 which has holding contacts 9. A D.C. supply is provided at the terminals 7. Relay 8 closes contacts 10 in circuit with the coil 5 and in series with the cam-operated contacts 11, so that a series of impulses are transmitted to coil 5 and through a pawl associated with the toothed wheel effects backspacing. The arm 4 carries a bracket 13 in which slides a toothed rod 14 which is normally spring-urged away from the centre of the turntable, but is prevented from moving by a second pawl, which can be withdrawn by energizing a coil 15. The coil 15 is energized by closing a switch 22 which energizes a relay 21 and closes the contacts 23 which energizes a relay 19 through the normally closed contacts 18 of the switch 16. The relay 19 has contacts 24 in circuit with the coil 15 and hence when the relay 19 is energized the member 14 is released and moves outwardly until it opens the contacts 18 and is locked by the second pawl. Backspacing is then limited to the point where the member 14 engages the switch 16, opens the contacts thereof and de-energizes the relay 8. Specifications 697,161 and 819,996, [Group XL (a)], are referred to.

Title: Improvements in or relating to apparatus for effecting the movement of couches, tables or the like, relative to their supporting member or members
IPC: A61G7/018
Filed: 1948-05-04
Abstract: 643,614. Control of A.C. motors. GENERAL ELECTRIC CO., Ltd., and BRYER, R. F. May 4, 1948, No. 12253. [Class 38(iii)] An electric motor is adapted to tilt a couch or the like between extreme positions, means being provided to interrupt the movement of the motor-driven member when it attains a pre-determined position, such as the horizontal position, intermediate the limits of its movement, the movement being interrupted either for a short period or until the motor is re-started by an operator. As shown, the driving motor 1 is of the capacitator type having main auxiliary and brake windings 2, 3 and 4 respectively and a capacitator 5. When the couch is to be moved to the horizontal position, a threeposition foot-operated reversing switch, having contacts 6 and 7, is adjusted to afford the desired direction of rotation, the motor-circuit being completed through a rotary limit switch 8 which may be mounted with its axis coincident with the lateral axis of the couch. When the couch has reached the horizontal position, a switch 10 is broken by a motor-driven cam and the motor will stop since the current passing through a transformer primary winding 11 is insufficient to operate the motor. The switch 6-7 may then be opened, the couch being retained in the horizontal position. If the switch 6-7 is not moved, current is induced in the transformer secondary winding 13 and a thermal element 12 will eventually become sufficiently heated to make contact with terminal 14 and short-circuit the winding 11 so re-starting the motor. Movement of the motor-driven cam will reclose the switch 10 and the element 12 will cool and return to its normal position. The thermal switch may be replaced by other time-delay devices. In the modification of Fig. 2, the couch is returned to the horizontal position by appropriate movement of switch 6-7, a switch 21 occupying the position shown when the couch is not horizontal. A relay 15 is energized and closes self-maintaining contact 16. When the couch reaches the horizontal position, switch 21 is moved to its alternative position and a relay 18 is energized through contact 17. Contacts 19, 20, then interrupt the motor-supply. The motor is re-started by first moving the switch 6-7 to the " off " position and then returning it to an operative position. Clutch mechanism may be used for interrupting the movement of the couch when it reaches the horizontal position.
