Title: A programme switching device for a washing machine
IPC: H01H43/10
Filed: 1966-11-15
Abstract: 1,144,514. Programmer for a washing machine. CROUZET S.r.I. 15 Nov., 1966 [24 Dec., 1965], No. 51135/66. Heading H1N. [Also in Division Dl]  A programme device for a drum type washing machine comprises a cam 5 for reversing the drum driven continuously from a motor shaft 7 through a pinion 6 co-operating with cam-teeth 5b, and having tracks 5a controlling contacts, and a plastics integrally moulded cam 8 controlling, e.g. filling, heating, emptying, which can be driven with a step-by-step movement from motor shaft 7 through an electromagnetic clutch coupling cams 5 and 8, and having tracks 8b controlling contacts such as 9. The clutch comprises a fixed coil 13 with leads 14 in a case 12, 15 of soft iron secured to a fixed cam shaft 4 with the interposition of a magnetic core 11, and a magnetic core 16 attached to a grooved plastics mandrel 17 with apertures I7a for receiving projections 5c of cam 5 to rotate therewith. When coil 13 is energized it attracts core 16 against a return spring 18 and grooves on mandrel 17 co-operate with internal teeth 8g on cam 8 to rotate the latter. Cam 8 is located in its switching positions by a crownwheel 19 rotating with earn 8 through projections 8d received in apertures 19a and co-operating with a fixed crown-wheel 21 against which it is biased by a spring 20. In a further form (Fig. 7) an additional cam (23) rotationally mounted on cam 5 is driven at a different speed through a pinion (24) co-operating with cam teeth (23b). In another form (Figs. 8, 9), an additional cam (25) is axially displaceable on shaft 4 through a manual push-button on a shaft 10, its two axial positions controlling different operations and being defined by a spring (26) on cam (25) engaging notches (4c) in shaft 4. Cam (25) rotates with cam 8 through projections 8d received in apertures (25f). Spacer columns 3 have a bore receiving a selftapping screw or a rivet for refixing after repair (Figs. 10-14). When a contact (C1, Fig. 15) is closed, the cam 5, closing a contact (C2) during every rotation, sends a short impulse to coil 13 and cam 8 is driven with a step-by-step movement. When a manual contact (C3, Fig. 15) is closed, cam 8 is driven with a continuous movement. When, during step-by-step movement, an interchangeable memory part of cam 8 closes a contact (C4, Fig. 15), cam 8 is driven with a continuous movement during the closure of this contact. The step-by-step movement is interrupted during the filling, heating and emptying processes, a pressure-stat (P, Fig. 15) and a selected thermostat (T1 or T2) initiating resumption of the step-by-step movement. During these processes, the motor current is uninterrupted. Cam (23, Fig. 17) can produce different time intervals by inter-connecting various selected contacts.

Title: Reel Drive
Inventor: EICHELSHEIM RICHARD
IPC: G06K13/26
Filed: 1967-11-10
Abstract: 1,155,480. Reel drives. INTERNATIONAL BUSINESS MACHINES CORP. 10 Nov., 1967 [11 Nov., 1966], No. 51274/67. Heading G5R. A reel drive for winding a tape (especially a paper tape) between supply and take-up reels past a tape processing (especially a punching) station includes separate friction drive means for the supply and take-up reels respectively, the friction drive means for the supply reel being adapted to wind the tape in one direction, and the friction drive means for the take-up reel being adapted to wind the tape in the opposite direction, and means for varying the frictional engagement of the respective drive means in accordance with the tape tension. As shown in Fig. 2, a supply reel is mounted concentrically below a take-up reel, unpunched paper tape being shown on the left and punched tape on the right. When the punch station (not illustrated) starts punching the tape, the return loop over a tensioning arm 3 becomes longer, so that arm 3 is able to pivot (about the reel centre) counterclockwise, thus reducing the tensions in springs 6 and 10. Lever 8 then pivots about 14, causing a friction wheel 20, driven by a motor M, to drive the take-up reel clockwise. When the loop shortens again, the wheel 20 is returned to a position where it slips against the take-up reel. During driving of the take-up reel, the feed loop over a roll 33 and a tensioning arm 2 is correspondingly shortened, whereby a friction wheel 19 is disengaged from the periphery of the supply reel, permitting it to rotate counterclockwise (the wheel 19 tending to rotate it in a clockwise sense). For re-winding, the functions of the reels are reversed. High speed re-winding may be accomplished by depressing a lever 28 to bring an intermediate wheel 24 into contact with the supply reel. As shown in Fig. 5, lengthening of the return loop over tensioning arm 69 permits a spring 72 to pivot the arm about 70 so that a pin 68 causes a lever 67 to pivot at 66, 66a, Fig. 4. 66 is a shaft to which lever 67 and a fork-shaped member 65, Fig. 4, are both secured. The lower, longer, limit of the fork-shaped member 65 carries the bearing of a motor-driven friction wheel 60 which in consequence of the above movements is brought into contact with the periphery of a small disc integral with the shaft of the take-up reel. By simultaneous, similar, movements, a friction wheel 53, Fig. 4, is moved sufficiently far away from a driving disc at the lower end of a hollow shaft, surrounding the other shaft and connected to the supply reel to permit slip. Blade springs on levers 67 and 48 ensure resilient control. Again, for re-winding, the functions of the parts are reversed.

Abstract: 1,246,920. Transformers. SIEMENS A.G. 20 Oct., 1969 [18 Oct., 1968], No. 51433/69. Heading H1T. A tap changing arrangement has rectifier bridges 4, 5 connected, at the instant of tap position changeover, to two taps by means of selector switch arms 2, 3. Controlled rectifiers 60, 70 in the respective D.C. bridge arms have their negative poles connected by a capacitor 110. At changeover of tap positions, the unconnected selector arm is engaged with the next tap, the capacitor 110 then charging up to the tap differential voltage. A firing pulse then turns on the other controlled rectifier, causing the capacitor to discharge, thus ensuring rapid turn-off of the un-pulsed rectifier. Inductors 80, 90 enable the conductive rectifier to remain so during current zero conditions without the need of continuous firing pulses. Control of the alternating firing pulses would enable a gradual transition from one tap position to the other.
