Title: A signal transmission system
IPC: H04S1/00
Filed: 1960-02-10
Abstract: 936,188. Binaural systems; reverberation systems. WESTERN ELECTRIC CO. Inc. Feb. 10, 1960 [Feb. 19, 1959], No. 4682/60. Class 40 (4). A transmission system comprises a plurality of electrical signal transmission paths, each coupled with a different microphone and, connected between one such electrical signal transmission path and another such electrical signal transmission path, a bidirectional coupling path for transferring signal energy between said electrical signal transmission paths in both directions simultaneously, the bidirectional coupling path including means for providing a 5 to 30 millisecond delay for said signal energy. The system provides multi-channel stereophony, yet each channel when heard alone yields balanced monaural reproduction. Signals from two microphones 1, 2, Fig. 2, spaced apart in a studio 4, after passage through amplifiers la, 2a are respectively fed to A.M. and F.M. transmitters 14, 15. A bidirectional delay device 27 and a bidirectional amplifier 28 connect the output of amplifier 1a with the input of transmitter 15, and the output of amplifier 2a with the input of transmitter 14. Two loud-speakers 8, 9 reproduce the stereophonically related signals. The stereophonic effect is not destroyed by the delayed signals. Listeners to one transmission only, through one of loudspeakers 18, 22 hear both signals, one with a time delay, and the impression is of balanced reproduction with reverberation. Impedance matching conditions for the bidirectional coupling are described. In an alternative arrangement, Fig. 3, the bidirectional coupling includes a hybrid coil 30 balanced by network 32 and feeding a delay device 31 terminated for complete reflection by a short circuit or an open circuit. A combined delayed signal appears at both loud-speakers 8, 9. The delay device 31, Fig. 4, is terminated by a second hybrid coil 34 balanced by a network 36, the output signal from terminal g being fed by unidirectional amplifier 35 to input terminal f and thence back to delay device 31. U.S.A. Specification 2,819,342 is referred to.

Abstract: 465,679. Trueing grinding wheels. SCRIVENER, A. Feb. 17, 1936, No. 4710. [Class 60] A machine for forming a grinding-wheel c for helically grooved work such as screw threads comprises an annularly grooved crushing roller r which is so mounted as to be adapted for a swivelling adjustment relatively to the axis of the wheel for the purpose of accommodating itself to the helix angle of the work to be ground and which is slidable to and from the operative surface of the grinding-wheel in a direction at right-angles to said axis and which is also adapted for a tangential oscillating sliding movement across the face of the wheel. The roller r is mounted on a shaft t carried by a bracket k attached to a flange j of a sleeve i of an oscillatable shaft g mounted in bearings h in a slide d which may be moved by a hand wheel e to bring the roller into operative engagement with the wheel. The oscillation of the shaft g gives the roller a tangential oscillating movement across the face of the wheel. In order that the roller may be adjusted according to the helix angle of the work the bracket k is adjustable about an axis at right angles to the axis of the shaft g by means of screws m operating through arcuate slots n in the flange l of the bracket, a fine adjustment being obtained by screws o engaging opposite sides of a peg p projecting from the flange j. A diamond 5 movable across the face of the wheel is used to produce initially a true cylindrical surface.

Title: Method of making nuclear fuel bodies
IPC: G21C3/62
Filed: 1969-01-29
Abstract: 1,201,013. Fuel elements. GULF GENERAL ATOMIC Inc. 29 Jan., 1969 [7 Feb., 1968], No. 4806/69. Heading G6C. A nuclear fuel body made from particulate nuclear fuel for use in a high temperature nuclear reactor is formed by providing a chamber, e.g. the fuel chamber of a fuel element or the cavity of a mould, loading the chamber with particulate nuclear fuel to the desired density, forcing a fluid binder under pressure into the loaded chamber so as to uniformly fill the chamber by occupying the interstices between the fuel particles, and heating the aggregate of fuel particles and binder to a temperature and for a time sufficient to pyrolyse the binder and form a solid fuel body. The fuel may comprise ThC 2  as fertile material and a mixture of UC 2  and a diluent (e.g. ThC 2 , graphite or Be 2 C) as fissile material. The fissile and fertile fuel particles are preferably spheroids with average diameters of 200 microns and 400 microns, respectively, coated with pyrolytic carbon. When the fuel body is formed in situ, the fuel element casing containing the fuel chamber should be of a material e.g. graphite, having sufficient porosity to facilitate the escape of the volatiles created during pyrolysis. Suitable binders include thermoplastic materials such as pitch and organic polymeric thermosetting materials or resins. Phenolic-type resins are preferred because they provide a high percentage of carbon residue per weight percentage of initial resin. Overall shrinkage of the binder during pyrolysis is reduced by the addition of filler materials, e.g. graphite powder and activated carbon or charcoal. Cracking of the fuel particle coatings due to shrinkage of the binder is prevented by coating the fuel particles each with a suitable bond release agent such as powdered graphite or a high m.p. wax. The wall surface of the chamber may be treated with a suitable sealant e.g. a phenolic resin or furfuryl alcohol, prior to particle loading and binder injection, so as to prevent seepage of the binder into the sidewall of the chamber. The fuel bodies may be made in a mould which allows a closer matching of the fuel body to the dimensions of the fuel chamber of the fuel element. The fuel bodies made thus may be bonded to the walls of the fuel chamber with a suitable glue, e.g. coal tar pitch or a thermosetting resin.

Abstract: 617,056. Automatic speed control systems. TUSTIN, A., and METROPOLITANVICKERS ELECTRICAL CO., Ltd. March 24, 1943, No. 4824. [Class 38 (iv)] [Also in Group XXXVII] A control system for a power-driven movable object, in which the velocity of the object depends upon the speed of rotation of a hand wheel 1, has an additional hand wheel 29 arranged so that small movements thereof produce large changes in velocity. The hand wheel 1 drives a tachometer 7 which controls, through an amplifier 50, the field of a generator 41 supplying a motor 40 driving the object, the wheel may also drive, through reduction gearing, a potentiometer 24 which is in series with the tachometer and so impart a component of velocity to the motor 40 dependent upon the displacement of the wheel 1. The wheel 29 can be pressed inwards to disengage a friction clutch, and then turned to make a quick adjustment of the potentiometer 24. The actual velocity of the motor 40, as indicated by the voltage across the potentiometer 51, is opposed to the control voltages derived from the tachometer 7 and potentiometer 24 in the input of the amplifier 50. The system functions similarly to that disclosed in Specification 577,315, [Group XXXVII], as regards control by handle 1. A switch 45 can cut-out the potentiometer, whereupon the system functions similarly to that described in Specification 579,050, [Group XXXVII]. The amplifier 50 may be of the vibrating type described in Specification 616,516. The tachometer 7 may be replaced by a selsyn type of positional control similar to that described in Specification 616,518.
