Abstract: 730,752. Control of motors. SCHWAB, M. June 19, 1953 [June 20, 1952; July 10, 1952; Aug. 29, 1952 ; Feb. 6, 1953], No. 17041/53. Class 38 (3). [Also in Group VII] Starting and stopping.-Auxiliary driving means to continue the rotation of a sewing- machine slowly to a predetermined position after the main drive has been disconnected is controlled by means acting on a contact device, part of which rotates synchronously with the machine, to select the predetermined position. In the arrangements described, the rotating contact member has two insulating pieces moving in separate paths, and a stationary contact or contacts in an electric circuit controlling the auxiliary drive is or are movable to render effective one or other of the insulating pieces so-that the circuit is broken at different parts of the revolution of the machine; by shifting the contact or contacts when the machine is at rest it may be driven from one predetermined stopping position to another. Various forms of contact device are described, the contacts being arranged at different radii on the face of a disc or axially spaced on the periphery of a drum ; the stationary contact or contacts may be moved by a flexible cable from a control treadle or push-button, or by electromagnetic means similarly controlled, and may be adjustably carried so that the stopping position can be adjusted. In a modification, the contact-pieces determining the stopping positions are stationary, being engaged by rotating brushes, and are selectively connected in the circuit by a switch actuated by the control means. In the arrangement shown, devised to produce an automatic reverse rotation of 45 degrees from the first to the second stopping position, a conducting disc 50, rotated synchronously with the machine by a belt 43, carries insulating pieces 51, 52 placed at different radii and selectively engageable by a stationary brush s, these pieces being arranged on the disc so that when each comes opposite the brush the machine is in the corresponding required stopping position. When the treadle 33 controlling the main drive is released, a switch G energizes a relay S1 from supply terminals K through the frame of the machine, disc 50, and brush s, to energize the auxiliary drive H from mains R to drive the machine slowly until the insulating piece 51 comes into contact with the brush, whereupon the relay S1 is de-energized and the drive stops. The dropping of this relay closes a circuit for the solenoid M, which draws the brush down, against a spring, to energize the relay S2 and complete a reverse circuit for the auxiliary drive H through the disc 50 and brush s, so that the machine is driven backwards until the insulating piece 52 engages the brush and opens the circuit of the relay S2; the solenoid M may be de-energized after a suitable interval by means not shown. The use of low voltage enables all the wiring to be kept below the table top.

Title: Recording apparatus
IPC: G11B3/36
Filed: 1966-04-21
Abstract: 1,121,889. Dictating machine. INTERNATIONAL BUSINESS MACHINES CORP. 21 April, 1966 [30 April, 1965], No. 17427/66. Heading G5R. A dictating machine, wherein a transducer head 20 is moved by lead-screw relative to an endless magnetic recording band 12, is provided with an arrangement for backspacing the head so that an operator can listen to the recording previously made, a repositioning device for indicating the furthest extent of the previous transducer advance, and a system for automatically terminating readvance at this point on playback, to enable recording to be recommenced. Relay switches control the general operations of the machine. Backspacing is effected by energizing an electromagnet which moves the head assembly back by exactly one leadscrew tooth each time it is energized. The repositioning device incorporates a pin wheel memory 50, which when backspacing is initiated by the operation of an appropriate control switch is immediately actuated from solenoid 48 via link 64 to store the rotational position reached by the transducer drive shaft 18, an appropriate pin being pushed into a set position. A coarse memory device 24 is also used, and incorporates a set of switch contacts carried forward by the transducer head during recording. These are left at the position of furthest advance when backspacing is initiated. On playback, the pin memory rotates a number of times, and contacts 51 are closed by the set pin, but the automatic readvance termination circuit, which includes these contacts, is not operated because the contacts in the coarse memory, which are also in the circuit, remain open. When these are closed by the arrival of the head, the next closure of the pin memory switch at the exactly correct position of the head along the tape closes the readvance termination circuit. This releases a clutch between the drive motor and shaft 18 to disconnect the drive. Alternatively the pin wheel memory may be operated through reduction gearing so that it makes only one rotation during a full operative traverse of the head across the recording belt. One dictating apparatus may be used by several operators, in which case guard zone facilities are incorporated which prevent one operator playing back the information recorded by another. This necessitates marking both the beginning and end of a particular recording, using the pin wheel memory.
