Title: Improvements in and relating to the production of coke breeze
IPC: C10B49/10
Filed: 1961-02-16
Abstract: 901,783. Carbonizing coal; purifying gas. SIMON-CARVES Ltd. Feb. 16, 1961 [May 30, 1960], No. 5723/61. Classes 55 (1) and 55 (2). In a fluidized process of carbonizing particulate coal the gases leaving the fluidized bed are passed through a layer, preferably also fluidized, of particulate metal oxide to remove tar and fine particles of carbon. The metal oxide may be hematite, magnetite, ironstone, minette, ferrous oxide or copper oxide. The oxide may be withdrawn from the layer of oxide, regenerated by oxidation and returned to the layer for further use. In the apparatus shown, particulate coal is fed into the uppermost of three fluidized zones 4, 5 and 6 and is preheated there by rising gases before being passed via pipe 13 to the carbonization zone 6. A mixture of air and a combustible gas supplied at 7 is burned in the zone 6 to carbonize and fluidize the preheated coal therein and coke is withdrawn through a standpipe 3. A mixture of combustion and distillation gas passes upwardly through a bed of metal oxide in zone 5 and then through the preheating zone 4 to a gas outlet 2. The gas withdrawn may be used in part to supply heat to the carbonizing zone 6. Metal oxide is continuously fed to and withdrawn from the bed 5 via a feeder 18 and an outlet 21.

Title: Improvements in and relating to semiconductor arrangements
IPC: H01L29/76
Filed: 1966-02-14
Abstract: 1,138,493. T.F.T. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 14 Feb., 1966 [17 Feb., 1965], No. 6386/66. Heading H1K. In an insulated gate field-effect transistor the width of the effective source-drain path is increased in a direction towards the drain by shaping the gate electrode, the semi-conductor body, or both. This is stated to provide a substantially uniform field in the device. An enhancement mode T.F.T. is made by the vapour deposition on to a glass substrate of gold source and drain electrodes (4, 3), by the vapour deposition of a film (5) of N-type cadmium sulphide having a sheet resistance of 10<SP>8</SP> ohms per square, by the vapour deposition of silicon oxide gate insulation (6), and by the deposition of a gold gate electrode (7) through a mask providing a notched pattern as seen in Fig. 3 (not shown). A depletion mode T.F.T. may be made from cadmium sulphide with a sheet resistance of 10<SP>6</SP> ohms per square, the only other difference being that the sulphide layer (5) is given the notched pattern instead of the gate electrode. In variants of both transistors, the semi-conductor body, the gate electrode, and the gate insulation may all be correspondingly shaped. In further variants notching may be effected from end to end to divide the part affected-in the case of a gate electrode so treated the parts are then externally connected in parallel-or the notches may be omitted and only the outer edges of the part shaped. Other semi-conductors suitable are cadmium selenide, tellurium, zinc telluride, tin oxide, indium oxide, and gallium arsenide. Magnesium fluoride is an alternative gate insulation. The specification states that the transistor may share a common semi-conductor body with further elements such as other thin film transistors.

Abstract: 774,475. High-frequency supply systems for space discharge apparatus. TOUVET, G. Jan. 12, 1951, No. 6512/53. Divided out of 774,471. Drawings to Specification. Class 38 (4). [Also in Group XL (a)] Apparatus for producing optical radiation (infra-red to ultra-violet) comprises a gas (particularly xenon) or vapour-filled coiled or folded discharge tube excited by electric current of radio-frequency (or by radio-frequency components of current pulses) between two identically similar electrodes, the frequency, waveform and strength of the exciting current, the composition and pressure of the gas or vapour filling and the shape and dimensions of the tube being so chosen in combination that one or more lines in the spectrum of the filling are split into a multiplicity of lines by the magnetic field set up by the current flowing through the tube and that the intensity of the resulting radiation is enhanced in one or more regions of the spectrum by increasing the amplitude of particular spectral components or by broadening a line spectrum into a band. A coiled tube has a higher self-inductance than a folded tube and is suitable for use at lower radio-frequencies. The radio-frequency of the exciting current may be above 50 Mc/sec. and can be between 60 and 100 Mc/sec. In a particular example described a xenon-filled discharge tube consisting of two coaxial coils is excited by current at 100 kc/sec. Currents of about 1 ampere and 100 amperes per sq. cm. are referred to. Small changes in the frequency of the exciting current cause small shifts along the spectrum of the enhanced bands of the radiation and large changes cause the enhancing of the spectral lines to occur at a different part of the spectrum. The tube can have a sinusoidal input or can be operated in Class B or Class C or by very short D.C. impulses, of the order of 1 microsecond, containing radio-frequency transients. Circuits for exciting the tube are described in Specifications 774,471, 774,474 and 774,477. The tube may form part of the inductance of a tank circuit or may generate oscillations through possessing negative resistance as referred to in Specification 774,471. Applications to television, lowaltitude altimetry, range-finding, radar and remote control are referred to. Specification 386,492 also is referred to.
