Title: Pyridine-4-aldehyde acetals
IPC: C07D213/51
Filed: 1956-02-22
Abstract: The invention comprises acetals of pyridine-4-aldehyde derived from aliphatic, cycloaliphatic or araliphatic alcohols of not more than 10 carbon atoms per molecule, and their manufacture by reacting pyridine-4-aldehyde with an aliphatic, cycloaliphatic or araliphatic alcohol, or with a corresponding orthoester, if desired in the presence of an esterification catalyst such as hydrogen chloride or ferric chloride.  In examples, pyridine-4-aldehyde is reacted with (1) ethyl orthoformate; (2) methanol; (3) menthol; and (4) benzyl alcohol to give the corresponding diethyl, dimethyl, dimenthyl and dibenzyl acetals.

Title: Improvements in or relating to short wave oscillation generators
IPC: H01J25/68
Filed: 1932-02-27
Abstract: 397,555. Valve generating circuits. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., Marconi House, Strand, London, and GILL, E. W. B., Merton College, Oxford. Feb. 27, 1932, No. 5940. [Classes 39 (i) and 40 (v).] In generating short-wave oscillations by the Barkhausen-Kurz method, the damping action of the grid current, which is normally out of phase with the anode current, is avoided by so arranging the electrodes of the valve, and the connections, that the grid is located substantially at a potential-node in the main oscillatorv circuit. As shown the anode takes the form of a pair of part-cylindrical surfaces 3, 4 arranged on each side of the grid 2, the anode diameter being not less than 2¢ times the grid diameter. The anode-portions 3, 4 are connected together in series through Lecher-wires 5, 6 with a bridging-piece at one end connected to the cathode 1. Oscillations occur along the Lecherwires, one potential node being located at the bridge-terminal, and the other at the doublecondenser formed between the two anodeportions 4, 5 and the interposed grid. With this arrangement, the grid and cathode leads may be inserted at one end of the glass bulb, and the anode lead at the opposite end. Also the whole oscillatory system may be housed inside the glass bulb, the two anodes 4, 5 being connected by an internal loop of wire.

Abstract: 846,665. Thermionic valves. WESTERN ELECTRIC CO. Inc. Feb. 23, 1959 [March 12, 1958], No. 6103/59. Class 39(1). In high frequency apparatus comprising an electron discharge device including a flat cathode, a control grid closely adjacent the cathode and an anode and means including the cathode and control grid defining an input cavity resonator having therein an asymmetrical electric field the control grid 17 comprises a flat supporting disc having an elongated aperture 39 therein and a plurality of fine wires 40 extending transversely across the aperture, whereby the electromagnetic transmission characteristic of the control grid is independent of its orientation in the input cavity. Apart from the control grid, the discharge device may be of the kind described in Specification 668,355 and may be mounted in an amplifier cavity or support similar to that shown for the modulator of Specification 676,840. It has been found that the use of a control grid having a circular or square aperture results in only 70% as much leakage field existing in a direction transverse to the wires as exists in a direction parallel to the wires so that a grid with an aperture as shown, or a rectangular or oval aperture, having a width equal to about 70% of its length is preferred. For example the lengths A and B may be 0À225 inch and 0À165 inch respectively and the wire may be 0À0003 inch in diameter, wound at 1000 turns to the inch. Specifications 650,667 and 653,153 also are referred to.

Abstract: A constituent of a rustproofing material consists of a liquid produced by nitriting an alkyl derivative of a cyclic alcohol by means of an acid and an inorganic nitrite and, after the reaction is complete, adding a solvent for the organic nitrite and filtering. For example, 2-methylcyclohexanol is mixed with sodium nitrite and water and to the mixture, which is agitated vigorously, aqueous sulphuric acid is added and the resultant liquid cooled continuously until the reaction is complete. Methylated spirit is then added and the liquid is filtered.ALSO:A material for rustproofing metals, e.g. for browning gun barrels and gun parts, includes a liquid produced by nitriting an alkyl derivative of a cyclic alcohol by means of an acid and an inorganic nitrite and, after the reaction is complete, adding a solvent for the organic nitrite and filtering.  The rustproofing material may consist of about 3 per cent of the liquid so formed together with water and one or more metallic salts.  In an example 2-methylcyclohexanol is mixed with sodium nitrite and water and to the mixture, which is agitated vigorously, a mixture of 1 part of pure sulphuric acid and 2 parts of water is added, the resultant liquid being cooled continuously until the reaction is complete. Methylated spirit is then added and the liquid is filtered.  The filtrate may be mixed with a saturated solution of ferrous sulphate, a solution of antimony chloride, copper sulphate, and water to form a rustproofing material.  The steel &c. to be rustproofed is cleaned and polished with lime water before the material is applied.
