Title: Improvements in or relating to a method and apparatus for feeding batch materials
IPC: C03B3/00
Filed: 1954-03-12
Abstract: 750,544. Charging glass-melting furnaces. PITTSBURGH PLATE GLASS CO. March 12, 1954 [March 24, 1953], No. 7238/54. Class 51(2). In a hopper feed arrangement for charging granular materials, e.g. glass batch ingredients, onto a molten bath, the base of the hopper 30 is closed by a reciprocating feed plate 32, the apertured front wall 38 is provided with a series of vertically movable plates 39 extending across said aperture the centre plate being kept lower than the others, and the centre of the aperture is provided with a fixed vertical distributer 42. Each reciprocation of the plate 32 forms a log 36 of batch material on and extending across the molten bath, the combined action of the central plate 39 and the distributer 42 reduces the cross section of each log, so that as it passes into the furnace under the back wall 22 it soon splits into two logs which separately follow the convection currents of the bath, Fig. 2 (not shown), leading to rapid and even melting of the batch material. The distributer 42, Fig. 3, comprises a prefabricated wedgeshaped structure secured by brackets 44 to the front wall 38 and rear wall 40 of the hopper 30. The apparatus is said to be also applicable to furnaces for the manufacture of sodium silicate and the extraction of copper from copper concentrates.

Title: Stabilizing resistance in semiconductor manufacture
IPC: H01C1/144
Filed: 1967-02-15
Abstract: 1,133,807. Thermistors. CARBORUNDUM CO. 15 Feb., 1967 [4 March, 1966], No. 7247/67. Heading H1K. The room temperature resistance of a silicon carbide thermistor with metal electrodes fused directly to it by a bond consisting of carbide and silicide of the electrode metal, which both have an oxidizing temperature below that of silicon carbide, is increased to a desired stable value by briefly heating to a temperature intermediate the oxidizing temperatures of silicon carbide and the electrode carbides and silicides. The heating is carried out in one or more stages before encapsulation, where the encapsulant is a resin or both before and after encapsulation where a ceramic or glass frit encapsulant is used. In a typical case the device is a boron doped monocrystalline disc of silicon carbide with tungsten electrodes welded to it along diametral lines by passing a current between them. After encapsulating in glass frit and firing at 700-750 C. the device is heated at 925 C. for periods of 1-5 seconds for a total time between 5 and 22 seconds.

Title: Method of melting manganese steel
IPC: C21C7/00
Filed: 1923-03-13
Abstract: 215,895. Marks, E. C. R., (American Manganese Steel Co.). March 13, 1923. Alloys.-A method of melting manganese steel scrap consists in subjecting the scrap to fusing temperature in a relatively inert environment, and under the protection of a covering of slag, while providing iron at, and also preferably above, the level of the slag. The iron is preferably incorporated in the lining of the melting furnace and the roof also will preferably be lined with basic material. A convenient method is to line the furnace with bricks composed of a sheet metal jacket filled with magnesite, the jacket melting and running down into the slag to neutralize the oxidizing influence of the latter.

Title: Improvements in the gauging of internal screw threads
IPC: G01B3/48
Filed: 1939-03-08
Abstract: 526,118. Screw thread gauges. COVENTRY GAUGE & TOOL CO., Ltd. HARLEY, S. J., and WAINWRIGHT, J. E. March 8, 1939, No. 7483. [Class 106 (ii)] Relates to the kind including one or more gauging members arranged for radial displacement within the screw threaded hole and means for measuring the displacement, and consists in using for such members freely rotatable rollers having screw-thread form serrations. The body d of the gauge is adjusted along a table e fixed to a grinding machine to bring the gauge into gauging position on the centre line of the hole f<SP>1</SP> in the backpiece f held in chucks g. Gauge blocks b are inserted between the body d and the carriage c so that when the body is adjusted on the table e to bring the grooved gauging roller a carried thereon into contact with one side of the hole f<SP>1</SP>, micrometer i carried by the body and acting on the other side of the carriage is. at zero position. An adjusting screw j in a lug on the table and engaging the body facilitates this adjustment. The gauge body is then clamped to the table by the clamping bolt l. The blocks h are now removed and the carriage displaced by the micrometer i until the roller a engages the diametrically opposite side of the hole. The reading of the micrometer plus the diameter of the roller gives the diameter of the hole. The roller a has annular serrations and is mounted on a pin b fixed to the carriage. A long pin n passes through the pin b and is fixed to the roller a so that the latter may be rotated about and moved axially relative to the pin b to judge proper contact. In a modification two such rollers and carriages are used, one carriage being fixed. The fixed carriage may be reversible so that the device may be used for gauging larger holes. The gauging rollers may be replaced by feelers of D-shape the curved portions being grooved. The grooves on the rollers may be discontinuous and flats formed thereon to facilitate engagement with the holes.

Title: Improvements in and relating to protective apparatus for alternating electric current systems
IPC: H02H3/28
Filed: 1923-03-15
Abstract: 216,254. British Thomson-Houston Co., Ltd., and Fitzgerald, A. S. March 15, 1923. Addition to 193,434. Cut-out arrangements.-In protective arrangements for alternating current systems and apparatus employing a biassing transformer with operating and secondary windings inductively related to one another and a restraining winding not inductively related to the other two windings, as described in the parent Specification, the operating, secondary and restraining windings are each divided and equal portions of each are mounted on each of two core parts constituting the magnetic structure. In the form shown in Fig. 1, in which a single three-limbed core which may have an air-gap, is employed, the outer limbs are wound with one half of each of the three windings 2, 3, 4. The portions of the restraining winding 4 on each core are reversely connected to one another so that the winding as a whole is not inductively related to the other windings. In order to control the effect of the restraining winding when conditions are normal, a variable or fixed resistance is connected in shunt with the winding or an additional short-circuited winding 17, inductively related to the restraining winding and provided with a fixed or variable resistance 16, may be divided between the cores. These means for controlling the effect of the restraining winding give the same advantages as if there were an air gap in the magnetic circuit. The biassing transformer may comprise two separate ring cores 5, 6, Fig. 2, upon each of which are arranged equal portions of the three windings, the portions of the restraining winding on each core being reversely connected and the portions of the other two windings being connected in the same sense. The arrangement is shown with a variable resistance connected in shunt with the restraining winding.

Abstract: 783,987. Fluid-actuated valves. PEEBLES & CO., Ltd. Jan. 23, 1956 [March 16, 1955], No. 7641/55. Class 135. An automatically-controlled gas governor 12 includes a set of cams each of appropriate contour for a separate period in a predetermined programme, a cam follower engageable successively with each cam, and means coupling the cam follower to a device for varying the setting of the governor in conformity with the movement of the cam follower. The diaphragm of the governor is loaded by a weight 23 rolled along a lever 21 by a lever 27 carrying the cam follower. Seven cams driven by clockwork are positioned coaxially on the shaft of a starwheel 15. A kicker 19 for forming a complete revolution with each cam turns the star-wheel one tooth at a time and through a scroll cam 13 on the star-wheel shifts the cam follower from one cam to the next and, when the seven day cycle of operations has been completed, transfers the follower from the last to the first cam, a shoe 34 engaging a projection 37 to lift the follower clear of the cams during the transfer movement.
