Title: Pulse generating circuits
IPC: H03K3/64
Filed: 1972-04-28
Abstract: 1414321 Pulse generator MARCONI CO Ltd 19 Jan 1973 [28 April 1972] 19773/72 Heading H3P  A pulse train generator comprises a plurality of minor pulse generators the pulses of which may be sequentially added together in duration so as to form a pulse of duration equal to the sum of the durations of the pulses so added and control means responsive to the magnitude of each pulse for maintaining the magnitude of each output pulse substantially constant at a predetermined amplitude. The minor generators A, B and C are controlled by a timing control source 9 which operates the pulse generators to produce desired pulses. These pulses are added via diodes 13, 15 and 17 to appear on an output line 19. The amplitude of the final pulse is maintained constant despite the adding of pulses which might be of different amplitudes by providing a clamp on the points 10, 11, 12 via respective drops 14, 16, 18 in response to the amplitude of the first pulse of the final pulse. This is effected by sensing via diode 26 the amplitude of the first pulse and applying a clamp voltage via capacitor 22 to the cathodes of diodes 14, 16, 18.

Abstract: 908,623. Velocity modulated tubes. VARIAN ASSOCIATES. June 3, 1960 [June 5, 1959], No. 19805/60. Addition to 819,660. Class 39 (1). In a velocity modulated tube of the type described and claimed in the parent Specification, the co-operating portions ensuring alignment of the tube elements comprise guideways 24 formed in the sides of the cavity resonator 17, a pair of resilient guide members 51 fixedly mounted upon a mounting member 36, fit slidably within the guideways and serve to align the resonator with the tube elements, including the cathode 45. The reflex klystron shown has a steel envelope 11 having an iris opening 13 across which is sealed, by a " Kovar " (Registered Trade Mark) frame 15, a ceramic window 14. The cavity resonator is formed by two steel sections riveted together, a pair of U-shaped members 21 being riveted to the cavity so that on heating the resonator members bow outwardly and increase the grid spacing so maintaining the frequency constant. Alternatively, 18<SP>1</SP> is of copper-plated steel and 18 of copper, members 21 being dispensed with. Resonator flanges 24 form a V-groove for mounting a pair of elements which align the electrode assembly and cavity resonator relatively to one another. The electrode assembly is carried by mica plates 36 from two thrust plates 35 secured to ceramic-metal base 31, 29. The mica plates 36 are spaced by wires 37 and integral eyelets 37<SP>1</SP> and also by the aligning elements fitting in the V grooves 24. The focusing electrode 41 is mounted by tabs 42 and has four legs 44 to support the cathode button. The reflector is mounted by tabs 49. An exhaust tube 32 is sealed in ceramic base 31 by a " Kovar " collar 33. Electronic tuning is achieved by reflector voltage variation. A waveguide flange adapter has longitudinal and transverse spring fingers and the reflex klystron has a key fitting in a slot therein for circumferential locking, Fig. 6 (not shown). Alternatively, the waveguide flange is brazed to the klystron envelope, Fig. 8 (not shown). A tunable external cavity resonator may be heavily coupled to the internal resonator and comprises a tuning screw and wave trap mode suppressor. In this case, Fig. 9 (not shown), members 14, 15 are sealed to a waveguide flange instead of across iris opening 13.

Title: Improvements in money saving clocks
IPC: G07F17/00
Filed: 1919-08-13
Abstract: 154,667. Lindblad, E. L., and Lindblad, E. A. Aug. 13, 1919. Savings boxes; coin action, mechanical-connexion.-Relates to clocks for collecting sums of money, such as insurance premiums, at predetermined intervals. The clock is not stopped at the termination of an interval, but its face is covered by a screen so that in the event of delay in inserting the required coin there is no need to restart the clock and set the hands. Fig. 1 shows one form of mechanism employed, the screen 4 being held away from the clock aperture 3 by a pin 20 engaging a shoulder on the spring lever 18. At the predetermined time, a pin 22 on a wheel 23 driven by the clock depresses the lever 18 and thereby releases the screen 4, which is raised by its spring 7 in front of the clock face. At the same time, the coin shoot 9, which is pivoted at 8, is moved forward so as to withdraw from it the pin 17, allowing a coin, or the lowest of a series of coins, as shown in Fig. 5, to descend to the open end of the shoot and rest on the plate 27. The apparatus can now be reset by turning the spindle 13, Fig. 4, by means of the handle 15, or a removable key. The arm 14 then bears on the coin and moves the shoot inwards, causing the screen 4 to be lowered until the pin 20 is reengaged with the shoulder of the lever 18. Dur. ing this movement, the lever 18 is displaced to one side, as shown in Fig. 4, to allow its upper part to pass the pin 22 on the wheel 23. In an alternative arrangement, a spiral spring surrounding the pivot of the screen 4 replaces the spring 7, and a rigid lever actuated by a spring is used instead of the spring lever 18. The coin may be pushed back by the direct action of a spring pusher instead of the arm 14 on a rotary spindle.
