Title: Process and apparatus for producing nuclear energy
IPC: G21D5/02
Filed: 1962-08-29
Abstract: 1,000,050. Nuclear reactors. DEUTSCHE FORSCHUNGSANSTALT FUR LUFT UND RAUMFABRIK E.V. Aug. 29, 1962 [Aug. 29, 1961], No. 33167/62. Heading G6C. [Also in Divisions F1 and H2] A method of producing energy comprises establishing a stabilized confined plasma of fissile material, producing a nuclear reaction in the plasma, passing a gaseous working medium over the surface of the confined plasma, and using the working medium for power generation. In the rocket engine shown in Fig. 1 a fissile gas, e.g. uranium hexafluoride, continuously passes from a storage tank 1 through a preheater 2 into the reactor, and may be preheated resistively or inductively by a coil (not shown) placed round the cylindrical inlet tube. On entering the reaction chamber the gas is ionized by the magnetic field of H.F. coil 6 to form a plasma and the plasma is stabilized by a magnetic field produced by a magnet coil 7 in a reaction zone 3 where fission reactions occur. The reaction chamber comprises a number of steel tubes 4 welded together to form a cylindrical chamber and surrounded by a reflector-moderator 5. After the fission reaction is established a working fluid, e.g. liquid hydrogen, is introduced into the tubes 4 and flows through the space 9 between the reaction space and the walls of the chamber to the nozzle. In a modification designed to produce an electrical output, Fig. 2 (not shown), the nozzle is replaced by a magnetohydrodynamic generator comprising electrodes and a magnetic field perpendicular to the electrodes and to the direction of gas flow. Moderator such as heavy water may be mixed with the fissile material before it enters the reaction space.

Title: Improvements in or relating to suspension arrangements for road vehicles
IPC: B60G11/00
Filed: 1933-11-29
Abstract: 429,596. Vehicle spring - suspensions. ARMSTRONG, F. G. G., 14, York Road, Beverley, East Yorkshire. Nov. 29, 1933, No. 33401. [Class 108 (ii)] In a spring suspension for road vehicles of the kind in which each wheel is independently supported at the outer ends of a pair of longitudinally extending levers that pivot about transverse axes on the vehicle frame, the suspension spring 32 acts directly between an arm 22 carried by the frame and either one of the levers 24, 25 or the link 28 connecting these levers. In the construction shown in Fig. 1, the spring 32 is disposed vertically with its lower end acting upon a platform 33 at the outer end of the upper lever 24, its movements in compression and recoil being limited by pads 36, 37 mounted adjustably or otherwise upon a central rod 34. The stub axle 20 is secured to a sleeve 29 surrounding the link 28. In a modification, Fig. 3, (not shown), of this arrangement, the pad 36 is spring-controlled, and the arm 22, instead of being mounted at an independent point of the vehicle frame 21, is disposed at the pivot 26 of the upper lever 24. In another construction, the arm or bracket on the vehicle frame is arranged below the levers, and a spring acting in tension is utilized. In still further modifications, the suspension spring acts upon the lever 24 or 25 at an intermediate point or is associated with a lug extending from the vertical link, or, as shown in Fig. 6, may surround this link 41 and thus dispense with the necessity of providing a separate guide rod for the pads 36, 37. If desired, an auxiliary spring 44, Fig. 9, may be utilized to counteract the leverage effect due to the stub axle being spaced at a small distance laterally of the frame, and the spring 32 may be inclined to assist in the same object. The spring 32 may also be inclined in the longitudinal plane of the vehicle so as to act substantially in the direction of the inclined force arising when the wheel encounters a protuberance in the road surface.

Abstract: 1,080,356. Thermionic valves. TELEFUNKEN PATENTVERWERTUNGS G.m.b.H. Aug. 17, 1964 [Aug. 23, 1963], No. 33453/64. Heading H1D. In a circuit arrangement for amplifying or generating U.H.F. signals including a thermionic valve having an indirectly-heated cathode, the construction of the cathode and heater is so arranged, or components are provided, so that the cathode-heater resonances of the valve lie outside the working frequency band of the arrangement. The cathode-heater resonances may be shifted above the working frequency band by use of a short, thick heating element with heavy gauge supply leads to reduce the inductance of the heater circuit, and by use of a short cathode, e.g. having a diameter greater than its length, and multiple, thick, low inductance cathode supply leads. Alternatively, a helical heater may be embedded in a high dielectric material spaced from the cathode to increase the capacity between adjacent turns of the heater, or the space between the cathode and heater may be filled with a low dielectric material to reduce the heater-cathode capacity. A dielectric material may be provided between the ends of the heater and the cathode tube to produce a capacitive susceptance which may be compensated by a corresponding input circuit, or separate condensers may be inserted between the ends of the heater and the cathode tube. The cathode-heater resonances may also be shifted below the working frequency band, the arrangement then being such that the cathode to grid series resonance lies above the working frequency band.
