Filed: 1975-06-28
Abstract: 1509569 Pyroelectric camera tube circuits ENGLISH ELECTRIC VALVE CO Ltd 28 April 1976 [28 June 1975] 27425/75 Heading H4T A gas-filled pyroelectric camera tube has a circuit (Fig. 4) for applying line blanking pulses to the cathode and positive-going pulses to the grid (G1) at the same time as the blanking pulses in order to establish a pedestal potential on the screen. The blanking pulses ensure that the cathode is positive with respect to the target so that the electron beam does not reach it. However, positive ions are produced and land on the target. The number of such ions is increased by the pulses applied to the grid which is normally at potential of -25V. The pulses may have an amplitude variable from just below zero to + 14V. In the circuit shown, transistor 20 inverts pulses applied to it through differentiating network 22, 23, 24. The amplitude of the pulses may be varied by means of the potentiometer 26, 27. Grid bias is applied through transistor 31 and an OR gate constituted by diodes 28, 33. The tube (not shown) has a target of triglycine sulphate and a filling of hydrogen or an inert gas.

Title: Improvements relating to the catalytic conversion of hydrocarbons
IPC: C07C5/27
Filed: 1939-10-19
Abstract: 537,705. Hydrocarbons. STANDARD OIL CO. Oct. 19, 1939, No. 28259. Convention date, Dec. 21, 1938. Drawings to Specification. [Class 2 (iii)] As the catalytic isomerization of normal paraffins is inhibited by the presence of aromatic hydrocarbons, feed stock containing them is treated prior to the isomerization with known selective solvents to remove the aromatics or with low molecular weight olefines to alkylate the aromatics which are then removed by distillation. If the feed stock contains naphthenes, whose presence too is undesirable, the latter are converted by known catalytic methods into aromatics which are then removed together with any aromatics originally present. The aromatization of the naphthenes is effected by heat treatment with hydrogen in the presence of a catalyst comprising a mixture of alumina and chromic oxide, nickel or platinum on magnesium chromite, platinum black, palladium, nickel or reduced copper; temperatures of 500‹-1,000‹ F. may be employed and hydrogen pressures of 0.2 to 10 atmospheres. Solvents mentioned for the removal of the aromatics are furfural, nitrobenzene, nitromethane, liquefied sulphur dioxide and the aluminium chloride complex referred to below, preferably used in countercurrent at temperatures between -40‹ F. and 120‹ F. The isomerization treatment is preferably effected in the presence of hydrogen using an aluminium halide catalyst activated by a hydrogen halide ; the hydrogen may be that formed during the aromatization stage. Temperatures employed are then 180‹-450‹ F. with hydrogen pressures of 500-4,000 lb. per sq. inch but in the absence of hydrogen pressures of 50-500 lb. per sq. inchare sufficient, the temperature range being the same. The products of the isomerization include a complex of the aluminium chloride used as catalyst with hydrocarbons formed, and this complex is useful both as a solvent for the removal of the aromatics and for admixture with fresh aluminium chloride to be used as isomerization catalyst. When alkylation of the aromatics is resorted to, olefines containing 2, 3 and 4 carbon atoms are employed and the process is effected at a temperature of 50‹-225‹ F. under a pressure of 15-100 lb. per sq. inch in presence of aluminium chloride activated with hydrogen chloride or the aluminium chloride complex above referred to. The aromatic separated in the foregoing processes are useful as solvents and the isomerized paraffins as motor fuels. Processes are described in detail with reference to two flow diagrams.
