Title: Pulse train delaying device
Inventor: OYA YUICHIRO
IPC: H03K5/135
Filed: 1963-02-05
Abstract: 1,020,586. Pulse delaying and storage circuits. HITACHI SEISAKUSHO KABUSHIKI KAISHA. Feb. 5, 1963, No. 4710/63. Heading H3P. In a system for delaying a train of m pulses fed to terminal 1, the pulses are distributed via m AND gates A 1  . . . A m  to m diode/capacitor stores M1 . . . M m  under control of an mphased clock pulse supply fed to the second terminals α 1  . . . a m  of the AND gates. The first pulse of each train is thus stored in M 1 , the second in M 2  and so on. The stores are read by the next clock pulses fed to the inputs d 1  . . . d m  so that after recombining in the OR circuit O, the complete train will have been delayed by one clock pulse period. The delayed train may be re-shaped in a regenerative amplifier or bistable circuit F. Fig. 3 shows one of the stores M 1 . Each input pulse at terminal 3 charges capacitor C via diode D1. The charging time constant is sufficiently long to prevent the clock pulse simultaneously present at terminal 5 from turning on the back-biased diode D 2 . Capacitor C stores the energy of the pulse until the next clock pulse arrives at 5 when diode D 2  is turned on, discharging the capacitor via the output terminal 4. Fig. 6 shows another store in which capacitor Ca does not begin to charge until the end of each short-duration clock pulse at 5a and is discharged via diode D3a by the next clock pulse at 5a.

Abstract: 576,295. Echo-sounding recorders. HUGHES & SON, Ltd., H., SPARLING, S. C., and HUGHES, A. J. March 14, 1944, No. 4730. [Class 118 (ii)] [Also in Group XIX] An echo-sounding recorder, wherein a stylus moves over a comparatively narrow chart, is provided with means for effecting a displacement of zero while at the same time indicating directly the value of the trace without other calculation. A uniformly-moving chart b is covered by the operative sweep of a stylus f rotating with the emitter switch e, which is depressed once per revolution by a ramp h on a plate j angularly adjustable by a spindle k. The adjustable spindle k also carries a transparent circular graduated dial n and a locating disk o held in the desired position by a detent q on the hinged front l. By displacing the position of zero by adjusting the dial n, relatively to the fixed scale s and the chart b, an extended range of direct recording is secured. When the stylus follows a rectilinear path, the circular dial n is replaced by a polygonal plate.

Patent GB-1168849-A (GB)
Title: Microwave Oscillator
IPC: H03B9/12
Filed: 1967-02-01
Abstract: 1,168,849. Oscillator circuits. INTERNATIONAL BUSINESS MACHINES CORP. 1 Feb., 1967 [2 Feb., 1966], No. 4800/67. Heading H3T. [Also in Division H1] In a Gunn effect diode, an electric field set up between its terminals by a voltage greater than a first threshold voltage V T  produces a succession of moving high-field domains whose time of transit between the terminals defines a frequency (the transit time frequency) at which the device generates current oscillations. The invention is based upon the discoveries that: (a) there exists a second and higher threshold voltage V T1  and if this is exceeded during the transit of a domain a second domain can be initiated before the first is extinguished; and (b) if during the transit of a domain the voltage falls below a sustaining value V s , the domain will be extinguished before reaching the cathode terminal. The invention proposes various oscillators in which these discoveries are exploited by combining a Gunn diode with circuitry such that the voltage across the diode is itself caused to oscillate, in particular: (a) between a value less than V T  and a value above V T1 ; and (b) between a value less than V s  and a value above V T  with a periodicity less than the transit time. The means controlling such voltage variations may include a tuned circuit (Fig. 1A, not shown), whose frequency may, but need not, be a harmonic of the transit time frequency. If it is a harmonic, the oscillator is termed a " resonant mode " oscillator and two such oscillators are distinguished viz. " under voltage resonant mode " in which the minimum voltage across the diode is less than V s  and " over voltage resonant mode " in which the maximum voltage is above V T1 . The invention embraces the possibility of permanently energizing the Gunn diode 11, Fig. 1B, from a voltage source 10 and employing a load circuit 18 such that the voltage V D  across the diode is less than V T . A signal generator 22 in series with the diode can however be operated to apply a triggering signal which momentarily raises V D  above V T . This will trigger an oscillatary condition in which V D  oscillates over a range embracing V T  and it is found that such oscillation persists after the initiating signal has been removed. The oscillation can however be stopped by applying through the signal generator, a signal of opposite polarity to the original triggering signal.

Other constituents of compositions for these purposes are: fatty alcohol sulphate, tetrapropylbenzene sulphonate, fatty acid ethanolamide, waterglass, magnesium sulphate, sodium chloride, alkalimetal tri-polyphosphate, alkali-metal pyrophosphate, sodium sulphate, fatty acid amide, magnesium silicate, hydroxyquinoline, caustic soda, caustic potash, and sodium carbonate.ALSO:An ammonium borate perhydrate, free from water of crystallization, is prepared by reacting boric acid, at least 30% hydrogen peroxide, and ammonia in molar ratio 1:2-6:1.05-4.  The reaction should be effected with 40-70% H2O2 at 0-30 DEG C. and the H2O2 and boric acid are mixed first. When aqueous, preferably concentrated, e.g. optimum saturation point at 0 DEG C., NH3 solution is added to the two mixed reactants ammonium metaborate diperhydrate NH4BO2,2H2O2 is formed.  When gaseous NH3 is passed into the other mixed reactants ammonium perborate diperhydrate NH4BO3,2H2O2 is formed.  The precipitated diperhydrates may be separated and dried in vacuo at 30-50 DEG C. The mother liquor may be reused in the process.  Stabilizers, e.g. magnesium silicate, alkali metal, pyrophosphate, and hydroxy quinoline may be added to the diperhydrates, which may be used in bleaching baths, and as washing, cleaning, and dispersing agents, if desired, in combination with alkalies, (caustic soda, or potash, or sodium carbonate), detergents, alkali metal phosphates, and alkali metal silicates.  In examples: (1) a coarse washing agent contains fatty alcohol sulphate from coconut oil fatty acids, alkylbenzene sulphonate, waterglass, magnesium sulphate, fatty acid ethanolamide from coconut oil fatty acids, sodium chloride, alkali metal tripolyphosphate, alkali metal pyrophosphate, sodium sulphate, ammonium metaborate-diperhydrate, an optical brightener, and water, with, or without, a dyestuff; (2) a fine washing agent contains C12-C18 fatty alcohol sulphate, tetrapropylbenzene sulphonate, fatty acid ethanolamide from coconut oil fatty acids, fatty acid amide from coconut oil fatty acids, common salt, sodium sulphate, ammonium perboratediperhydrate, magnesium silicate, an optical brightener, and water.

Abstract: 624,355. Automatic firearms. BRISTOL AEROPLANE CO., Ltd., FONSECA, E. C. M. D., and GREEN, S. March 6, 1945, No. 5617. [Class 92(ii)] An ammunition supply system of the kind in which the ammunition is disposed remotely of the firearm is characterised in that the rounds of ammunition travel over at least a part of their path in a separated condition and in that each round is automatically engaged by a spacing member which is carried along therewith, when moving along this path, to maintain the long axes of the rounds parallel to one another, the spacing member being automatically disengaged from the round prior to the latter entering the gun. In the construction shown, the rounds.are fed in belt form from a supply source beneath a turret through a shoot 11 as described in Specification 624,354, and are stripped from the belt by mechanism 12 as in Specification 598,658, the stripped rounds being fed to a pair of guns 10 as described in Specification 624,357 under the control of a deflector plate located adjacent a fork 14 and constructed as in Specification 624,356. Thus, the rounds after being stripped at 12 are delivered to a passageway 13 and pass thence to the telescopic arms 17 of accumulator shoots 15 and thence via adits 18 to the guns. To maintain the stripped rounds parallel to one another, each is automatically fitted on its nose with a ring 19 having a diameter substantially equal to the base of the round. These rings follow a closed circuit including accumulator shoots 24, similar to the shoots 15, and a further shoot 31. The rings are urged in a downward direction by sprockets 29 which are driven by sprockets 28, the latter engaging the rounds of ammunition and being driven thereby when the corresponding gun is firing. As shown in Fig. 3, the shoot 31 merges into the turret shoot 11 so that the rings 19 are gradually moved towards the rounds to fit over their noses, being prevented from falling into shoot 11 by a guide strip 32. The rings are applied to the rounds before stripping and as the rounds are then more widely spaced than the rings in shoot 31, a spacing device 36, Fig. 6, is provided. This device comprises discs 33 of polygonal outline, around which passes a belt 34 having fingers 35 adapted to engage the rings 19 and to space them apart. The discs are rotated by the belt through the agency of the rings located at 19a, 19b. The rings are removed from the rounds at points near the guns 10 by guide strips which engage the rings, the separated rings being delivered to the shoots 24.
