Filed: 1952-11-28
Abstract: 704,740. X-ray tubes. PHILIPS ELECTRICAL INDUSTRIES, Ltd. Nov. 28, 1952 [Dec. 3, 1951], No. 30217/52. Class 39(1) In an X-ray tube anode which is cooled by the impingement of a liquid spray on its under surface, a movable guide is provided between said under surface and the spray nozzle. In the example shown, the liquid enters through tube 18 into a metal box 19, and sprays through a perforated wall 20 on to the anode surface 21. In its path is a rotor 23 having curved arms 24, which the motion of the liquid causes to rotate about a pivot 25. The aim is to reduce fouling of the surface 21 when oil is used as the cooling liquid. The rotor arms may also carry brushes which sweep the surface 21.

Patent GB-306105-A (GB)
Abstract: 306,105. Holzverkohlungs - Industrie Akt.-Ges. Feb. 16, 1928, [Convention date]. Acetic, fomic, propionic, butyric, and other aliphatic acids.-In the production of concentrated acids by forming acid salts and then heating the acid salts, salt mixtures are employed which are wholly or in part molten during the subsequent heating stage. At least one of the constituents of the mixture must be capable of combining with the aliphatic acid to produce an acid salt, the remaining constituents reducing the melting-point of the mixture, but preferably each salt is capable of forming an acid salt. Suitable mixtures are alkali and/or alkaline earth (including magnesium) acetates or salts of other acids such as other fatty acids. The dilute acid may be treated in the form of vapour with a concentrated solution of sodium and potassium acetates, or the dilute acid may be treated with an organic solvent such as acetone oil, wood-spirit oil, ether, butyl alcohol, or mixtures of acetone oil with benzene and the like. the extract being then treated with the salt mixture. In an example, 50 per cent acetic acid is mixed with sodium and potassium acetates and distilled: at 170‹ C. most of the water is expelled as 10-12; per cent acid, and on raising the temperature up to 300‹ C., if desired with reduced pressure, the remaining acid is distilled off at 95 per cent strength, the mixed neutral acetates remaining in the retort. In another example, a solution of butyric acid in acetone oil is extracted in counter-current with a concentrated solution of potassium and zinc butyrates and the acid salt solution is then distilled; up to 200‹ C. about 15 per cent of the butyric acid is obtained in dilute form, the remainder being obtained at 70 per cent strength. The process may be employed for concentrating formic and propionic acids. Referercce has been directed by the Comptroller to Specifications 291,433, 291,434, 302,268, and 302,269.

Abstract: 1,260,491. Electrical systems for I.C. engines. MASSEY-FERGUSON-PERKINS Ltd. 3 June, 1969 [28 June, 1968], No. 30830/68. Heading H2H. A circuit for controlling the generator of an I. C. engine includes a switch responsive to the engine speed to energize the field coils of the generator only when the engine speed exceeds a predetermined value. As shown in Fig. 1, when a starter switch 6 is closed, a starter motor 3 is driven by a battery 1, and the engine is turned at a speed sufficient to cause oil pressure to operate a switch 20 connecting the field coil terminal 24 on the generator 16 to the battery through an indicator lamp 23. After the engine has fired, the generator provides its own field supply, the voltage of which is regulated by the battery voltage. When these voltages are equal, the lamp 23 goes out. When the engine is stopped, the generator is no longer able to provide its own supply, and the field coils are again fed from the battery through switch 20 and lamp 23 until the engine speed falls below the level at which the switch 20 operates. Then the contacts open and the lamp 23 is again extinguished. Instead of being responsive to oil pressure, the switch 20 may be operated by the inlet or exhaust manifold pressures, fuel pressure or a tachometer. The system is particularly suitable for use with compression-ignition engines.

Title: Improvements in or relating to apparatus for winding or unwinding webs of paper or like material
IPC: B65H23/195
Filed: 1932-11-04
Abstract: 409,724. Winding webs. BINGHAM, A., and MOLINS MACHINE CO., Ltd., 2, Evelyn Street, Deptford, London. Nov. 4, 1932, No. 31121. [Class 100 (i).] In web winding or unwinding mechanism of the type in which the reel-driving means is accelerated or retarded by means controlled by a brake responsive to the tension of the web, the driving means comprises a differential gear, and a brake operating on the casing thereof. The reel shaft 1 is driven by sprocket gear 2, 3, 4 from a shaft 5, to which is fast one gear-wheel 7 of a differential gear 6. The pinions 19 of the differential gear are mounted on a casing 18, the rotation of which is controlled by a brake band 8. The pinions are driven by a gear-wheel 9 fast to a sleeve 10 and driven through gears 11, 12 by a contant-speed motor. The pressure of the brake band is controlled, through a bell-crank lever and links, by a roller mounted on a spring-controlled arm and resting in a loop of the web. Thus as the tension of the web tends to increase due to the increased diameter of the roll, the brake is slackened and the casing starts to rotate, thereby retarding the roll. The mechanism may be applied to the spindle of a reel from which the web is being drawn and will then operate in an exactly contrary manner.
