Title: Tape transport systems
IPC: G11B15/54
Filed: 1975-09-10
Abstract: 1519780 Automatic control systems PERTEC CORP 10 Sept 1975 [13 Sept 1974] 37273/75 Heading G3R In a tape transport system, where tape is driven from a supply reel to a take up reel and a tape loop is provided between each reel and the tape drive, each reel is controlled, whilst the tape is stopped, in response to a signal proportional to a change in longitudinal position of the tape between the reel and a respective loop. As shown, under running conditions of the tape 12 past a read-write head 13, the speed of a tape drive capstan 14 is retroactively controlled, a capstan speed signal from tachometer 16 passing to a supply reel reference generator 19 where it is amplified by a factor dependent upon the measured tape loop position in vacuum buffer A. The resultant signal via ramp generator 27 (an integratoramplifier) is summed with a tape speed signal from tachometer 30, 31, 32 to form a control signal for supply reel motor 23, so as to maintain the loop in buffer A between limits set by sensors 2, 3. Under standby conditions i.e. with the tape stopped, the capstan speed signal is zero and unit 40 closes a switch 36 (e.g. an F.E.T.) so that the supply reel drive motor 23 is controlled by the signal from tachometer 30, 31, 32 proportional to the change in longitudinal position of the tape between reel 10 and buffer A, which signal is modified by a signal from ramp generator 27 if the tape is not positioned between sensors 2, 3. The tape driven tachometer includes a slotted cup rotor 30, an A.C. energized primary and a quadrature secondary winding. Under running conditions, discriminator 32 produces the tape speed signal, but for standby (switch 36 closed) the secondary winding output is rectified to produce the tape position signal. In this standby mode, motor 23 is controlled so that reel position drift is prevented independently of the size of tape on the reel 10. A similar control is provided for the take-up drive motor 24. Details of the tachometer 30, reference generator 19 and ramp generator 27 are given in Figs. 2-4 (not shown).

Title: Improvements in electromagnetically-operated selecting switches
IPC: H01H67/22
Filed: 1938-12-22
Abstract: 524,015. Electromagnet switches ; electric motor controllers. HINKS, B. Dec. 22, 1938, Nos. 37287/38 and 7902/39. [Classes 38 (iii) and 38 (v)] In an electromagnetic switch for controlling motors &c. the member 1 carrying the contacts 29 and the armature 2 is not only moved upwards towards the attracting electromagnet 10 but is also moved laterally in one or other direction so as to determine which fixed contacts are engaged by the contacts 29. In the form shown in Fig. 3, closure of a a "start" button 9 energizes the magnet 10 and attracts the member 1 so that the contacts 29 engage fixed contacts 28 and complete a "star" connection to a motor. Pins 4b on the member 1 are during this movement guided by the left-hand side of members 7. A rod 16 on the member 1 also closes contacts 14 in a retaining circuit which includes a bimetallic strip which after a short interval opens the contacts 14, de-energizes the magnet and allows the member 1 to drop into the "off position. Its swinging momentum then causes contacts 17 to be closed so that the magnet 10 is immediately re-energized. The pins 4b now move up the righthand side of the members 7 so that contacts 29 this time engage contacts 31 and effects a "delta" connection of the motor. In a modification, Fig. 6 (not shown), the two "on" positions of the switch are for " forward " or " reverse " and the initial lateral movement of the member is produced mechanically by the actual movment of the " forward " or " reverse " push-buttons. This initial lateral movement may also be produced electromagnetically, Figs. 7 and 8 (not shown). In a further modification, Fig. 9, successive energizations of the electromagnet 10 cause the pins 4b to engage alternate sides of rockable members 3 pushing them into alternative positions in which they are retained by a dead centre compression springs 8 acting on a bar 8a. Another modification, Figs. 12 - 14 (not shown), is similar to that shown in Fig. 3 excepting that in one position of the switch the motor is connected directly in circuit and in the other through an auto-transformer.
