Title: Improvements in or relating to encased magnetic cores
IPC: H01F27/25
Filed: 1961-09-12
Abstract: 937,320. Transformers and inductors. TELEGRAPH CONDENSER CO. Ltd. Sept. 12, 1961 [Sept. 14, 1960], No. 32674/61. Class 38 (2). An encased toroidal magnetic core has a central tubular non- magnetic section, with a winding of magnetic material thereon one or both ends of the tubular section, being deformed as in Fig. 5, to surround the winding. In the first embodiment (Fig. 5) a tube 14 of heat-resistant non-ferromagnetic material, such as stainless steel, is wound with the magnetic coil 16 and then formed to the required shape. When the coil 16 is annealed to give the required magnetic characteristics, no appreciable distortion of the element 14 occurs, which would stress the winding and alter its magnetic characteristics. The gap between the ends of element 74 is filled with an insulating cement or plastic 25. In another embodiment (Fig. 8) two preformed elements 14A and 14A1 co-operate. The magnetic wire or tape winding 16A is wound on element 14A, and the element 14A1 inserted. The unit is sealed at 25A, 26A. In further embodiments (Fig. 9, not shown, and Fig. 10) the winding 16c is on a single heat-resistant element 14c, and after annealing the unit is sealed with a plastic element 30c, which can be fitted without distorting the element 14c, and stressing the coil. Specification 800,054 is referred to.

Abstract: 840,455. Band brakes. BRITISH RAYON RESEARCH ASSOCIATION. Dec. 1, 1958 [Oct. 22, 1957], No. 32871/57. Class 103 (1). [Also in Group XXXII] To damp torsional oscillations in a roller, the length of which is many times its diameter, restraint is applied to the end of the roller opposite to the end which is driven. The restraint may take the form of a brake comprising a leather strap 18, having a weight 19 attached to one end, the opposite end of the strap being attached to the frame of a machine 20. The strap passes over a wheel 17 connected to a roller 11 the oscillations of which are to be damped.

Examples of the thermoplastic resin binder are styrene/ acrylonitrile copolymer, ABS resin, high impact polystyrene a cellulose ester resin, ethyl cellulose a homo- or copolymeric vinyl resin (other than those specified) and mixtures thereof. The cellulosic filler may be any wood flour although other substances such as cotton linters, hammermilled rayon and cotton flock may be used. The leather is preferably micronized. Metal soaps specified are the stearates, oleates, palmitates, ricinoleates and laurates of Ca, Al, Mg, Zn and Li; aluminium stearate is preferred. The composition may also contain 0À3-2 wt. per cent of moisture, which gives the pencil sheath a fine porous structure on moulding. Other ingredients such as dyes or pigments, and scenting agents may also be present. In the examples, an ABS resin and a high impact polystyrene are mixed with wood flour and aluminium stearate, and the composition formed into pencils by extrusion moulding around a marking core.

Title: Improvements in devices for enabling a numerical reading to be obtained from the trace produced by a watch-timing machine or similar instrument
IPC: G04D7/12
Filed: 1960-09-27
Abstract: 915,074. Measuring angles. MARTI, F., and BRAUNSCHWEIG, G. Sept. 27, 1960, No. 33154/60. Class 97 (3). [Also in Group XVIII] A device for enabling a numerical reading to be obtained from the trace produced by a watch timing machine or similar instrument includes at least one mobile setting attachment 1 adapted to be moved over the trace to be read, thus causing a relative linear displacement of at least one graduated scale 8 and at least one pointer 9. As shown, the mobile setting attachment is a disc 1 rotatably mounted on an axis 3 on the upper side of the watch timing machine on the path of a moving paper tape 10 on which the machine prints a diagram 11 which is inclined in one or other direction relative to the longitudinal axis of the paper tape 10, according to how fast or slow the time piece under test is running. The disc is provided with parallel slits 2 and is illuminated from below. The disc 1 can be rotated by means of an endless cord 4 which is looped around the disc and around two pulleys 5, 5a having control knobs 6, 6a. A pointer 9 is fixed to the cord 4 between two guide rollers 7, 7a which are arranged at both ends of two parallel rectilinear scales 8, 8a graduated in seconds per 24 hours and tenths of a second per 24 hours respectively. To measure from the diagram how fast or slow the time piece under test is running, one of the control knobs is rotated to rotate the disc 1 until the slits 2 are brought into a position parallel to the printed line 11 on the tape 10. This will shift the pointer 9 on scales 8, 8a on one of which the operator can read directly the error in running. Alternatively, the pointer may be fixed and the scales movable. In a modification the rotatable disc is replaced by a member which is movable linearly.

Abstract: 1368397 Nuclear fuel STUDIECENTRUM VOOR KERNENERGIE 18 July 1972 [26 July 1971] 33492/71 Heading G6C  Nuclear fuel carbide particles contain vanadium carbide as a supersaturated solid solution and are coated with a tin porous layer of vanadium carbide. Uranium carbide may be melted with 1À5 mole per cent vanadium carbide, the mixture solidified, annealed at 2000 C., cooled rapidly, and comminuted to a maximum particle size of 400 microns ; particles of size 20- 400 microns are spearated and coated by mixing with finely powdered vanadium monocarbidevanadium hemicarbide mixture, and the coated particles are shaped into a rod or pellet and sintered. Preferably the nuclear fuel particles are monocrystalline. During use of the fuel in a reactor, vanadium carbide precipitates out and forms a collector for gaseous fission products, which also escape through the porous coatings- and thus prevent swelling of the fuel. Uraniumplutonium carbide may be used in place of uranium carbide.

Title: Black level control circuit for a television receiver
IPC: H04N5/57
Filed: 1964-08-18
Abstract: 1,057,476. Controlling television picture signals. HAZELTINE CORPORATION. Aug. 18, 1964 [Oct. 3, 1963], No. 33691/64. Heading H3Q. In a television receiver keyed A.G.C. system with additional means for stabilizing the black level and limiting beam current in scenes of high average brightness as in Specifications 1,057,474 and 1,057,475 the video signal is applied to the cathode-ray tube and to the A.G.C. circuit via two networks of different A.C./D.C. transmission ratios. In Fig. 1 the output of the video amplifier 13 is split into two paths, in each of which the A.C. component is passed on fully via a capacitor (27, 33) while the D.C. component is attenuated by a voltage divider (25-26, 31-32). The first path feeds the cathode of the picture tube 20, the beam current of which supplies a feedback voltage across resistor 25 as in Specification 1,057,474. The second path feeds a keyed A.G.C. circuit 28 which is fed with positive flyback pulses from the line output circuit at 37. It is shown mathematically in the Specification that if the A.C./D.C. transmission ratios of these two paths are correctly related, the A.G.C. circuit will control the gain of the receiver in accordance with the average value of the video signal and at the same time preserve the black level. This arrangement derives the A.G.C. signal from the sync. pulse tips. In another arrangement (Fig. 3, not shown) the back porch level is used for this purpose, a delay circuit being ineluded between the horizontal deflection circuit and the A.G.C. tube to achieve this. In a modification (Fig. 4, not shown) applicable to both sync. tip and back porch keying, the voltage divider supplying the A.G.C. tube is connected to the right-hand side of the network 25, 27 of Fig. 1 so that the two networks are effectively in series for the supply to the A.G.C. tube. This arrangement uses a contrast control as in Specification 1, 015, 649.
