Title: Mining machine
IPC: E21C25/68
Filed: 1945-08-07
Abstract: 596,955. Mining-machines. RAMAY, E. Aug. 7, 1945, No. 20215. Convention date, July 3, 1944. [Class 68 (i)] In a mining-machine a pair of gangs of horizontal cutters are rotated relative to each other about vertical axes by a linkage disposed between them. The machine consists of a framework mounted on wheels 8, 9 and 19 of which the wheels 8 and 9 are driven separately from a motor 29 through clutches 36 and 37 and gearing 42, 44 and 49. The height of the frame, and its angle with respect to the ground, is altered by varying the position of each wheelmounting bracket 11 by means of screws 17. At the forward end of the frame are two vertical shafts 69, each composed of two sections upon each of which is mounted a section of a gang of chain cutter jibs. A motor 97 drives through bevel gearing 101 and 103 one of the shaft sections which drives through a chain 66 and a sprocket 54 a driving sprocket of the cutter chain of each jib. The vertical spacing of each jib with respect to a neighbouring jib is varied by a screw 92 situated between them and which is turned by a motor 108. For mining narrow seams the outer jibs may be removed. Each jib pivots about a shaft 62 and the angle between the two gangs of jibs is determined by the pivoted linkage 152, 153, 154 and 166 which moves in a slot in the main frame 7. The rear ends of the linkage are constrained to move along a screw 176 turned by a hand wheel 179. At the rear of the cutter jibs transverse conveyers 188 and 189 deposit the mined materials on to a longitudinal conveyor 186. In a modification, the drive of the jib chain is taken direct from a motor shaft to a sprocket on a vertical post about which the jib pivots and the loading is done by two vertical paddlewheels which scrape the material on to a stepped oscillating plate which discharges on to a longitudinal conveyer. U.S.A. Specification 2,320,653 is referred to.

Abstract: 486,174. Photographic stripping - papers ; colour photography. TRUECOLOUR FILM, Ltd., DOLGORUKI, E. SANDERS-, and REINDORP, J. H. July 23, 1937, No. 20461. [Class 98 (ii)] Photographic stripping material of the type comprising a base, an intermediate transparent or translucent layer, a stripping layer between the base and the intermediate layer and an emulsion layer carried by the intermediate layer comprises a stripping layer composed of a mixture of gelatine and a natural or synthetic gum or resin such that adhesion can be maintained between the intermediate layer and the base for sufficient time to permit the emulsion layer while carried by the intermediate layer to be coloured to form a colour component image while subsequently permitting removal of the intermediate layer with the coloured layer carried thereby from the support. A foil of regenerated cellulose or alginic acid or an alginate is adhered to a paper base by a stripping layer comprising gelatine, phenol and gum mastic, and a silver halide emulsion, for example a silver bromide emulsion, which may be colour sensitized, is applied to the foil. A multicolour screen negative may be copied on to such material using coloured printing lights. Prints may be made on to the material from colour component negatives and coloured images obtained by colour development, or chemical or dye toning. The paper bases are removed, and the first print is applied face down on the final paper support, which as been previously soaked in water and coated with 5 per cent gelatine solution. After drying, the surface of the cellulose foil is superficially moistened and the foil is detached from the emulsion layer. The remaining prints are applied in superimposition in a similar manner, gelatine solution being used to attach the layers.

Abstract: A catalyst for hydrogenating cashew nut shell liquid consists of finely-divided nickel dispersed in a "carrier" which may be cashew nut shell liquid or distillate thereof or their hydrogenation products.  The catalyst may be obtained by (1) heating nickel carbonate in a rotary furnace to 300-350 DEG  C. in the presence of hydrogen and dispersing in the carrier; (2) grinding up a nickel aluminium alloy, treating it with sodium hydroxide, washing with water and alcohol, dispersing in the carrier and removing the alcohol by heat; or (3) mixing nickel formate (preferably anhydrous) with the carrier and heating to 190-290 DEG  C. with constant agitation.  The ratio of nickel to carrier is preferably between 5 : 95 and 60 : 40 parts by weight. U.S.A. Specification 2,284,369 is referred to.ALSO:"Treated" cashew nut shell liquid is hydrogenated in the presence of a catalyst comprising nickel dispersed in a carrier which may be cashew nut shell liquid itself or distillate thereof or their hydrogenation products.  The ratio of nickel to carrier is preferably between 5 : 95 and 60 : 40 parts by weight, and the catalyst is present in an amount between 1/4 per cent and 1/2 per cent of the "treated" cashew nut shell liquid. The starting material is obtained by extraction from the nut shells or whole nuts and treatment of the extract with mineral acids or dialkyl sulphates at 250 DEG -400 DEG F. to remove potassium, calcium, magnesium, sulphur and nitrogen, and to decarboxylate the anacardic acid; the metallic salts are filtered off, leaving the "treated" cashew nut shell liquid, which consists mainly of phenols having unsaturated side chains of 14 to 28 carbon atoms. This liquid is mixed with the catalyst as above and preheated to 80-120 DEG  C. when hydrogen is passed in, the temperature being preferably held between 120 DEG  and 150 DEG  C.  An example is given showing the experimental details.  U.S.A.

Abstract: 1,220,115. Programmed control of mixing. K & M ELECTRONICS CO. May 1, 1968 [June 29, 1967], No. 20568/68. Heading G3N. A liquid dispensing device comprises a plurality of containers the flow from which is selectively initiated and timed by a switch means responsive to a selectively programmed signal device. As shown, a solenoid 10 actuates a valve 11 controlling the supply from a liquid container, (not shown), there being a valve and container for each of the liquids required for the range of cocktails for which the apparatus is programmed. The period for which the valve is opened, and hence the quantity of liquid dispensed, is determined by a silicon-controlled rectifier board 12 in dependence on which resistor is selected of a plurality of resistors in a unit 13 and applied to a resistivecapacitive firing circuit of the board 12. The components for each cocktail are stored in a magnetic tape memory 17 as a sequence of pairs of pulse trains. The first train selecting, through a pulse counter and a stepping switch 14, the desired value of timing resistor in unit 13, which is then held, during the second train which selects the solenoid actuating the valve for the desired component. On completion of the selection the valve 11 is actuated by the S. C. R. board 12 for the appropriate duration and subsequently the tape is stepped to select the next component. The containers for the liquids are either pressurized, or connected to constant level reservoirs to ensure that the flow through the solenoid valves is independent of level of liquid in the containers. It is stated that the initiation of cocktail dispensing can be effected manually or by a coin or a credit card.

Abstract: 792,846. Extracting zinc. WARLAND, E. July 18, 1955 [July 26, 1954], No. 20678/55. Class 82(1) [Also in Group XII] In a continuous process and an apparatus for reducing acidic zinc ores indirectly by means of carbon and in which the reduction of the zinc oxide is effected with an intermediate reducing agent in a bath of molten slag resulting from previous reduction of such ore, the pulverized ore with fluxes if desired is admitted through tuyeres 10 into the slag bath in the reducing compartment 2 which is in communication via passages 4, 5, with the regenerating compartment 3 to which powdered coal or coke is admitted by tuyeres 11 for the regeneration of the intermediate reducing agent (ferro-silicon iron, silicon, magnesium-iron) initially added to the slag. Zinc vapour is led from shaft outlet 8 to a condenser; slag is periodically tapped at 12, 13; heavy molten metals from the ore, e.g. copper, lead, may be run off as desired at 16, 17; combustion air preheated or enriched with oxygen, or oxygen itself, together with steam if desired are introduced by the tuyeres 10, 11. The ferro-silicon &c. reacts with the zinc ore in chamber 2 to liberate zinc vapour, the oxidized silicon and iron rising through passages 4 into the slag bath 3 where these oxides are regenerated by the coal or into (molten) ferro-silicon which sinks by gravity to pass back through passages 5 into the chamber 2, the cycle being continuous. The gaseous products, mainly CO and nitrogen, leaving at 9 may be burned and used to preheat the combustion gases.
