Patent GB-862787-A (GB)
Title: Conveyor apparatus
IPC: B65G21/14
Filed: 1959-04-20
Abstract: 862,787. Endless conveyers. JOY MANUFACTURING CO. April 20, 1959 [April 25, 1958], No. 13359/59. Class 78 (1). A mining machine 5 (Fig. 1) delivers coal to mobile tail section 8 of endless belt 14, said belt 14 delivers the coal to endless belt 4, but at 18 is turned at right-angles to form a loop 15 which passes round an end-roller mounted on carriage 20 placed under duress by a tensioning-unit 21. Carriage 20 moves automatically over rails 28 to take up the slack in the belt 14 as the mobile tail section 8 changes its position. Pivoted rollers 68 (Figs. 4, 5) carry loop 15 and move out of the way of the carriage to permit the latter to pass (see below). Carriage 20 (Fig. 2).-The carriage has wheels 26 running on rails 28 and carries end roller 22 for loop 15 of belt 14, which belt is guided by rollers 44, 46 carried by frame 200 pivoted at 37 to the carriage. The carriage carries sidecams 54. Pivotal rollers 68 (Figs. 4, 5).-Each roller 68, which carries upper run of the loop 15, is carried by sleeve 60 which pivots about post 62 when swung by the impact of the carriage on cam 76. The said sleeve is resiliently positioned by toggle mechanism 84, 86, 92 pivoting at 94 and carries roller 100 running on cam 104. Operation (Fig. 5).-When the conveyer tailsection 8 advances, the carriage 20 moves along rails 28. It clears the lower belt-supporting rollers 72 of the loop by passing over them, and clears the upper rollers 68 by dint of rotating them out of its path, the side cams 54 of the carriage engaging cams 76 of the sleeves 60 to cause the said sleeves, and therefore the rollers 68, to swing outwards against springs 82. The carriage therefore is capable of reciprocating to vary the length of belt 14, without the carriage being hindered by the rollers which carry loop 15.

Abstract: 104,131. Husebye, J. A. Oct. 4, 1916. Posts; erecting and removing posts.-In changing or repairing power transmission, telegraph, and like masts, the conductors are transferred to one or more auxiliary masts, temporarily mounted in or near the permanent masts, until the necessary changing or repairing has been effected, whereby the electric power need only be cut off for a short time, if at all. One form of auxiliary mast, Figs. 1 and 3, comprises an upper part 4 for taking the conductors, and a lower part 1 adapted to be fixed in a suitable position, and in which the upper part can slide to adjust the height of the mast. The height is adjusted by means of a winch drum 7. Each mast part is built of three angle-irons 18, 19 and staying-bands 20, 21 arranged as shown in Fig. 3.

Filed: 1976-04-07
Abstract: 1523004 Schottky barriers SONY CORP 7 April 1976 [25 April 1975] 14166/76 Heading H1K In a semiconductor device comprising a semiconductor substrate and a metal layer forming a Schottky barrier therewith a layer of amorphous or polycrystalline silicon containing from 2-45 atomic per cent of oxygen, and preferably having a resistivity of 10<SP>7</SP>-10<SP>11</SP> ohm cm. and mean grain size of 50-1,000, is so located on the substrate that it or its associated depletion region abuts the depletion region of the Schottky barrier to increase its breakdown voltage. Typically the silicon layer is coated with a layer of silica, silicon nitride, or nitrogen-doped polysilicon and the metal layer, e.g. aluminium is deposited in an aperture etched through the two layers to form a barrier with an N-type silicon layer. The oxygen-doped layer is preferably deposited from a mixture of monosilane and an oxide of nitrogen. Such a barrier may form part of a diode, the collector of an inverse bipolar transistor, or the gate of a planar JUGFET. In another variant the aluminium base contact of a junction-isolated NPN transistor is extended on to the collector zone to form the Schottky barrier therewith in order to reduce the switching off speed of the transistor. In an alternative form of didode an aluminium or chromium-gold layer forms a barrier with one edge surface of an etch patterned N type GaAs layer epitaxially grown on an intrinsic GaAs substrate, the diode being completed by an ohmic contact of goldgermanium or indium-silver on the layer.

Title: Process for the separation of solid and liquid fatty acids
IPC: C11C1/00
Filed: 1931-05-14
Abstract: Liquid fatty acids are separated from the solid ones in neutral fats or fatty acid mixtures by saponifying completely with a mixture of lime and soda or other alkalies forming an insoluble soap from the solid acids and a soluble one from the liquid acids, and filtering, centrifuging, or otherwise separating the soaps. Or the fat &c. may be first saponified completely to the soluble or the insoluble soap, and the soap partially transformed by treatment with the other alkali.  Preferably the proportion of lime or baryta to soda or potash corresponds to the proportion of solid to liquid fatty acids. In an example, 200 kg. of bone fat containing 45 parts of olein to 55 parts of stearin, is partially saponified in presence of sufficient water by 15 kg. of calcium hydrate of 90 per cent purity; 29 litres of 40 per cent soda lye are then added and the saponification completed.  The mass is left in cold water for a time, and then centrifuged or filter-pressed. The separated soaps are used as such or are decomposed by sulphuric or other acid to isolate the acids.
