Title: An arrangement and process for generating and maintaining very high temperatures sufficing for the production of nuclear reactions
IPC: H05H1/12
Filed: 1957-10-23
Abstract: 877,930. Thermonuclear apparatus. MAXPLANCK-GESELLSCHAFT ZUR FORDERUNG DER WISSENSCHAFTEN e.V. Oct. 23, 1957 [Oct. 23, 1956; Dec. 8, 1956; May 21, 1957], No. 33120/57. Drawings to Specification. Class 39(4). A process for producing very high temperatures in a light gas wherein the gas is introduced into an otherwise evacuated chamber and is ionised and heated, is characterized in that the gas is isolated from the walls of the chamber by means of a closed, non-alternating, externally generated magnetic field. The reaction chamber may be toroidal and filled with deuterium and/or tritium at a pressure of 10<SP>-3</SP> mm.; the chamber is surrounded by a number of main coils fed with D.C. to produce a closed non-alternating magnetic field of about 10,000 gauss. A current is induced in the gas by transformer action to ionise it and produce Joule heating and an alternating current is supplied to some of the main coils at a frequency equal to the gyro-frequency (about 50 mcs./sec.) to produce heat by exciting the characteristic oscillation of the ions in the main magnetic field; the main field is then increased to about 50,000 gauss to provide heating by compression. The gas is set in motion by setting up a moving magnetic field, for example by energizing in sequence a number of auxiliary coils, and the main magnetic field is modulated near the ion collision frequency to produce heating by the gyro-relaxation effect. The frequency may be between 100 and 1000 cycles per second, and an alternating current of this frequency may be superimposed on the D.C. supply to the main coils. The apparatus may be used to produce thermonuclear reaction and the energy produced may be extracted as an electric current in coils surrounding the toroid and tuned to the frequency of instability of the discharge.

Filed: 1927-12-10
Abstract: 307,544. Smith, W. S., and McLachlan, N. W. Dec. 10, 1927. Thermionic amplifiers.-In order to compensate for initial distortion due to attenuation of the side-band frequencies occurring in the highfrequency stages of amplification in a modulated carrier-wave receiver, the output circuit of a subsequent valve carrying low-frequency or rectified components is shunted by a tuned circuit or equivalent impedance network, which emphasises the voltage of those frequencies previously diminished, thereby restoring the average overall response. As shown in Fig. 6, a condenser 5 by-passes the carrier in combination with output chokes 6, 10. A variable resistance 7 is inserted in series with a parallel-tuned circuit 8, 9 across the output chokes. The tuned circuit 8, 9 mav be shunted by a resistance or capacity, whilst the inductance 8 may be replaced by a transformer or auto-transformer. The condenser 5 and choke 6 may be duplicated. As shown, the attenuation - correcting network 5 - - 10 is followed by a four-electrode or screened-grid valve 18 of high amplification factor, a choke 21 being included in the plate circuit to prevent back-coupling through the batteries. The invention is applicable to the output circuit of the first or second detector in a heterodyne or supersonic receiver.

IPC: F41G7/26
Filed: 1964-12-13
Abstract: 1,161,481. Recoilless weapon. BRITISH AIRCRAFT CORP. Ltd. 13 Dec., 1965 [13 Dec., 1964], No. 33598/64. Heading F3C. In a hand-held, recoilless, projectile launching system, a beam riding guidance device is employed. The launcher and guidance system are trained on the target and the projectile is steered into the beam centre by the guidance device. The system smooths over random movements of the tracking path or aiming line, by effecting beam stability, so that target tracking is not disturbed during the initial firing of the projectile. The guidance device incorporates an optical beam projector having a pulsed laser radiation source and a gyroscopically stabilized mirror system. The target is tracked by the operator by means of a telescopic sight mounted on the launcher. The mirror system is slaved directly to the gyroscope through a mechanical linkage while the gyroscope is precessed by an electromagnetic servo system mounted on the launcher. The servo system detects misalignment of the gyroscope relative to the launcher and supplies correcting signals through a feed-back loop incorporating torque motors. During firing the feed-back is interrupted and the gyroscope, and hence also the beam, is moved smoothly by control signals stored in a memory circuit.
