Convention date, Dec. 6, 1932. Drawings to Specification. [Class 39 (i).] An ultra-short wave device consists of a magnetron or Barkhausen-Kurz circuit comprising a tube having two, three or more electrodes of which the positive electrode oscillates on its length so that the frequency produced depends on the construction of the electrode, and the electrode consists of a spiral, either open-ended or short-circuited, such that the ratio of its length to its diameter is so great that the wave length generated or received is less than the length of wire in the spiral. The radius of the spiral is preferably so small that the spiral is close to the cathode space charge.

Abstract: 1,046,965. Fuel materials. UNITED KING- DOM ATOMIC ENERGY AUTHORITY. Aug. 5, 1964 [Aug. 20. 1963]. No. 32846/63. Heading G6C. Hafnium or a compound thereof is used as a burnable poison in an enriched nuclear fuel. Where the fuel is UC, the poison is HfC, and where the fuel is UO2, the poison is HfO2, and in these either of the fissile isotopes U235 or Pu239 can be used for enrichment purposes. The invention does not include the use of hafnium boride since in this material the isotope B10 is the effective poison, it having a considerably larger neutron captive crosssection than Hf. Sufficient hafnium is incorporated into the fuel to give a ratio fissile atoms: hafnium atoms in the range 1: 5 to 1: 10. A carbide fuel of the type described (UC-HfC) could be used in a high temperature gas-cooled reactor or as the anode of a gas- or liquid metal-cooled diode reactor. In the case of a water- or gas-cooled reactor, the carbide might conveniently be dispersed in a suitable metal matrix to form a cermet fuel.

Abstract: 506,799. Magnetic dust cores; moulding. VOGT, H. Dec. 1, 1937, No. 33255. Convention date, Dec. 1, 1936. [Class 38 (ii)] [Also in Group V] Cores for highfrequency coils are produced by pressure moulding magnetic dust and a hinder to approximately the finished shape and density, and then subjecting the provisionally moulded article while in a slightly plastic state to further pressure in a final mould whereby any intricate formations such as screw-threads required on the finished article are formed. For example, the screwed adjusting pin of a cotton-reel type core is produced by first compressing a mixture of iron dust and a binder such as phenol- or urea-formaldehyde into a plain cylinder which is partially hardened and then placed in a split mould 6 consisting of two parts hinged together at 7. The parts of the mould are internally threaded and held together by the walls of a recess in a swiveling plate 4 which may contain a series of recesses for other moulds. Final moulding pressure is applied by a plunger 8. which may have a rib 11 for forming a screw-mivex slot in the end of the core pin. A heating coil 5 may be provided where the binder used requires heat for softening. After moulding, the mould 6 is ejected by the ram 10 and opened for removal of the core pin which is then finally hardened. The cotton-reel body of the core may be formed by provisionally moulding the three parts 12, 13, 14, Fig. 3, and uniting them and forming an internal thread therein by a final moulding operation in the partially hardened condition.

The beam of a television picture tube is blanked by the application to an accelerating anode of pulses B (Fig. 1) derived via a filter 21 . . . 24 from pulses A which occur across a secondary winding 12 of the vertical output transformer 9, the latter winding supplying a posi - tive feed-back voltage via a potentiometer 17 and resistor 16 to linearise the charge of the timebase capacitor 2 which is periodically discharged by means of a switching device, e.g. a blocking oscillator 1, to produce the scanning control signals for the vertical deflection coils 11 which are coupled to a secondary winding 10 of the transformer 9 and an integrating negative feedback circuit 13, 14 being connected between the secondary winding 10 and the timebase. The transformer 9 may be a modified known type, the modification consisting of increasing the number of turns on winding 12 to provide the necessary amplitude of pulses B. Because of this the potentiometer 17 is employed to reduce the positive feed-back voltage to a desired value. This voltage may be given a shape suitable for ensuring correct spacing of the lines in the upper part of the picture when a tube with a flat screen is employed. Additionally, correct reproduction in the lower part of the image is brought about by the negative feed-back voltage produced by the integrating action of capacitor 14 and resistor 13 on the voltage wave C derived from the winding 10 supplying the deflection coils 11. The filter 21 . . . 24 effectively isolates winding 12 (which forms part of the charge circuit of capacitor 2) from undesired effects, e.g. due to the application of line blanking pulses to the same accelerating electrode and resistor 16 and capacitor 2 themselves constitute a filter which prevents such blanking pulses from reaching the switching device 1. Instead of including winding 12 in the D.C. charging path of capacitor 2 the modification shown in Fig. 2 may be employed. Specification 493,843 is referred to.
