Abstract: 749,780. Pulse modulation circuits. PATELHOLD PATENTVERWERTUNGS & ELEKTROHOLDING AKT.-GES. Aug. 10, 1953 [Aug. 8, 1952], No. 22020/53. Class 40 (5). Width modulated H.F. pulses from an amplifier V are passed over a self-biased rectifier Gs (which acts as a threshold device) to a backbiased voltage limiter valve B and a separate second rectifier Gv is employed which derives a D.C. voltage approximately equal to the peak voltage of the pulses and an adjustable proportion of this is applied by a D.C. source, valve Vv, from across its cathode load Rk, as bias to the input side of the signal channel rectifier Gs relative to that applied to the output side through a resistor Rs. The rectifier Gs may, as shown, be a push-pull arrangement with the centre tap of the energizing coil L, forming a part of the tuned input circuit, maintained at H.F. earth potential by a capacitor CE. A positive bias applied at Uo prevents the valve Vv passing current in the no-signal condition. The use of a second unloaded rectifier Gv enables a constant fraction of the peak voltage of the pulses to be obtained as bias even if a failing of pulses in one or more channels occurs in multi - channel operation. Specifications 656,502 and 647,844, are referred to. Reference has been directed by the Comptroller to Specification 656,502.

IPC: H01H25/06
Filed: 1965-05-25
Abstract: 1,133,601. Selector switches. MINISTER OF TECHNOLOGY. 24 Aug., 1966 [25 May, 1965] No. 22076/65. Heading H1N. A switch includes an array of stationary contacts, a plurality of contact-sliders arranged side-by-side for selective engagement with any one of the array of contacts and movable along separate paths across the array, and means which select and operate one of the contact sliders. In one form, Fig. 1, anti-clockwise rotation of a knob 48 (marked 1 to 36 to correspond with the 36 sliders 13) rotates a bracket 30 until a rack 38 is opposite the selected slider 13. At the same time a comb 41 having one long castellation (45) and thirty-six short castellations 44 is rotated until the castellation 45 is in line with the same slider 13. Clockwise rotation of the knob leaves bracket 30 and comb 41 in these positions due to the engagement of a spring plunger 36 in a detent 19. During this movement, a shaft 23 rotates relative to a shaft 20 carrying the bracket 30 so that a gear 37 is rotated by a worm thread 24 to drive rack 38 to the left to move the slider 13 until its contact 14 is opposite a selected one of the array of contacts 9. Further, anti-clockwise and clockwise movements of knob 48 will select and operate further sliders until all desired circuits are made. Any single slider can be returned to its right-hand position by depression of a button 26 when the knob is in the appropriate angular position, such depression causing rightward movement of the comb, via a rack 27, gear 40, and a further rack 46 on the comb, so that the castellation 45 moves the slider 13. When the knob 48 is in a neutral position, depression of the button restores all of the sliders by means of castellations 44. The left-hand and righthand positions of comb 41 are signalled respectively by the closure of contacts 66, 65 and of contacts 61, 63. A modification having a bevel gear drive to the actuating rack, and a cam arrangement for causing axial movement of the comb is also described (Figs. 4 to 7, not shown).
