IPC: F42C9/14
Filed: 1932-04-11
Abstract: 396,171. Projectile fuzes. JUNGHANS, H., Sulgen, near Schramberg, Germany. April 11, 1932, No. 10304. [Class 9 (i). A combined percussion and clockwork fuze for an antiaircraft projectile is made with the firing-pin of the percussion fuze in the longitudinal axis of the projectile and the balance for the clockwork fuze pivotally mounted about the aforesaid firing-pin or about a bush through which said firing-pin is guided. In Figs. 1, 2, and 3, the balance 13 is pivoted about a central bush 15 having a comparatively large diameter causing friction prolonging the period of oscillation, which may be further prolonged by the addition of a detachable weight 12. The escapement wheel 11 of the balance is driven through gearing by a centrifugal segment 7 formed with a nose 6 which until the appointed time holds up the shoulder 5 of a spring striker 3 arranged at the side of the central percussion striker 1. In a modification the spring striker 3 is replaced by a spring plunger at the side of or around the percussion striker and adapted to operate the percussion striker by striking a flange on the same ; this plunger is held up by a bevelled nose of a lever interlocked with the centrifugal driving segment of the clockwork. The percussion striker may be locked by a lever, which is swung out at the beginning of the operation of the clockwork, itself released by an inertia bolt or by a centrifugal spring lock 14. Fig. 1a shows a modified striker 3 mounted in conical bearings 37, 38 so that centrifugal force may help the action of the spring on the striker when this is released by the clockwork.

Title: Improvements in or relating to the production of strip sound records
IPC: G11B3/70
Filed: 1929-04-03
Abstract: 331,278. Gramophone Co., Ltd., (Radio Corporation of America). April 3, 1929. Records, combined photographic and kinematographic; optical; duplicating.-A record is duplicated by surface-printing from one flexible surface bearing the record on tn another flexible surface. A master, carrying ink or other substance, is prepared from the sound record to be duplicated and is used for printing a duplicate record upon a suitable carrier, the printing process involving the transfer of ink, or other substance, from the master to the carrier. The substance transferred to the carrier may be a pigmented liquid, or it may comprise a dye or substance which on subsequent treatment or upon coming into contact with a substance upon the carrier gives rise to a dye or other discolouration. The carrier may be transparent so that the record is adapted for reproduction by light transmitted through it, but preferably the carrier is wholly or partly opaque, the record being adapted for reproduction by light reflected either from the carrier or the ink. Carriers of cheap material, such as paper, may thus be used. The master may be a photographic film sound record the exposed portions of the negative being raised or lowered relatively to the remainder of the surface. In a preferred method, the photographic and chemical processes are carried out upon' a master in the form of a metal cylinder. The cylinder may be formed by covering a drum with a thin layer of wax which is graphited and then coated with a metal, e.g. copper, by electrolysis. The surface of the metal is then coated with a substance such as gelatine and a sensitizer, such as bichromate, ready to receive the sound record impression by a photographic process, the treatment being varied according to the printing process, such as collotype, swelled gelatine, or lithographic process, it is desired to use. The photographic sound record to be duplicated is wound helically round the prepared cylinder and the bichromated gelatine is exposed to light through the record. In order that the light shall fall normally upon the cylinder, a straight filament 1 is arranged in a box 2 having a reflector 3 and a number of mirrors 4, the drum 5 being revolved during the exposure. If a straight filament is not used, the light is reflected from a parabolic reflector and through an aperture in the top of the box to the drum. After exposure, the drum 5 is treated according to the printing process it is desired to use, after which the cylindrical shell is preferably cut along a helical line, to form a strip master. Alternatively, printing may be made from the master in the cylindrical form. A sound record may be combined with a picture record, Both records being printed from the same or different masters, either simultaneously or successively.

Title: Superregenerative superheterodyne wave-signal receiver
IPC: H03D11/02
Filed: 1949-04-22
Abstract: 662,666. Super-regenerative circuits. HAZELTINE CORPORATION. April 22, 1949 [May 12, 1948], No. 10768/49. Class 40 (v). A superheterodyne receiver having a saturation mode super-regenerative I.F. amplifier has its local oscillator output reduced or changed in frequency during the saturation period in order to prevent the intermediate and local oscillator frequencies recombining in the input-circuit to reproduce the signal frequency and so causing undesired re-radiations or ringing. In the circuit shown the signal is fed through a tuned circuit 38 to the grid of a valve 10 together with local oscillations obtained from an oscillator 45 through a capacitor 53. Valve 10 acts as a frequency changer and also operates as a superregenerative amplifier at the intermediate frequency by virtue of the circuit 13, 14, 15 which renders the valve oscillatory, and an R.C. quenching network 22, 23 in the cathode circuit. The audio frequency output is derived from a resistor 23 in the cathode circuit. A rectifier 60 is connected across the I.F. oscillatory circuit and during the saturation period provides a bias voltage which is applied through I.F. and L.O. frequency chokes 63 and 64 to substantially reduce or reduce or interrupt the output of the local oscillator. Variations in the input capacitance at the intermediate frequency modulate the amplitude of the local oscillator voltage and reproduce the signal frequency but this is reduced as described in Specification 662,667 by inserting a degenerative resistor 20 in the cathode circuit which is byepassed by a choke 25 so that it is only effective at the signal frequency. R.C. networks 28, 35 and 23, 35 are included in the grid and anode circuits respectively to maintain the mean quench frequency and mean anode current constant with changes in input signal amplitude and other circuit conditions, as described in Specifications 646,331 and 654,887. The self-quench network may alternatively be connected in the anode or grid circuit or an external quench supply may be provided. In an alternative circuit, Fig. 3 (not shown), the frequency changing is effected in an additional valve connected to the anode of valve 10 and biassed to cut-off, the degenerative resistor 20 being connected in its cathode circuit and choke 25 being omitted. Either circuit may be converted for F.M. reception by detuning circuit 13, 14, 15. Specifications 638,204, 648,920 and 657,239 also are referred to.

Abstract: 1283504 FET driver circuits NORTH AMERICAN ROCKWELL CORP 23 April 1971 [18 June 1970] 11094/71 Heading H3T An F.E.T. 2 driving an output 5 has a bootstrap capacitor 15 which enhances conduction of F.E.T. 2. When initial conduction of F.E.T. 2 changes the output 5 voltage sufficiently to operate a threshold device (F.E.T. 28 for example) which controls the application to C15 of a boosting voltage from for example a further boost-strap circuit (F.E.T. 30, C32). When the input is negative, a F.E.T. 7 earths the output 5, and a F.E.T. 26 earths C15, the point 16 being earthed by F.E.T.'s 31, 27. When the input goes positive F.E.T. 7 goes off, F.E.T. 26 goes off and allows F.E.T. 25 to turn on F.E.T. 2, and the output starts going negative (56, Fig. 3, not shown). F.E.T. 28 then conducts and turns off F.E.T. 31; and this makes point 16 go negative and the boot-strap action of C32 and F.E.T. 30 enhance this negative excursion, which is transmitted by C15 to enhance conduction of F.E.T. 2 to take the output fully negative (60). Reference is made to suitable selection of the conductance ratios of the F.E.T.'s, the relative values of the capacitors, and the supply voltage.
