Abstract: 602,075. Cutting glass tubes. GENERAL ELECTRIC CO., Ltd., SCRUTON, A. H., and DIXON, H. Nov. 28, 1945, No. 32138. [Class 56] [Also in Group XI] In a glass tube cutting machine having means for heating a narrow band around the rotating tube, means for chilling the band, and means for advancing the tube in steps of predetermined length, the means for rotating the tube about its axis comprises a pair of supporting rollers and means for rotating at least one of them. As shown, glass tubes 10 are supported on rubber-tyred idler rollers 11, Fig. 1 (inclined so as to urge the tubes against back stops 55), and on driving rollers 13 rotated from the main shaft 19, or from a separate electric motor, by a chain 67, Fig. 3, and are held down by the weight, or spring loading, of top rollers 56, 69 carried by bars 58, 72. The top rollers may be lifted clear for reloading &c. by pivoting the bars 58, 72 about one end, as at 73, Fig. 3, the opposite ends being then held up by pawls, as 61, Fig. 1, engaging shoulders 62 on arcuate guides 63, 63<SP>1</SP>. The rear tubesupporting means are all mounted on a carriage 43 which is driven (in the direction of the arrow 17) in short steps along rails 46 from a cam 24 on the main shaft 19, the cam engaging a roller on a lever 26, pivoted at 27, linked to a rack 32 connected through gearing and a free-wheel 38 to a lead-screw 41 ; the lever 26 is spring- loaded towards the cam 24, the point thereon at which the link to the rack 32 is pivoted being adjustable to vary the step length ; the carriage 43 may be freed from the lead-screw by unlocking the pawl 52 and manually withdrawing the half-nut 47. Flat-flamed burners 15 (see Group XI), and chilling wheels 16 (see below), are respectively mounted on bars 76, 91 supported at one end on spring-loaded levers 79, 97, Fig. 3, and at the other on levers 80, 98 linked to levers 85, 101 operated by cams 87, 103, Fig. 1, on the main shaft 19. In the inoperative position of the chilling wheels (adjustable by a screw 105), they dip into a water tank 106 and engage a belt driven by a chain 108. The main shaft is driven by an electric motor 18 through a gear-box 20, and the cams 24, 87, 103 are so arranged that for each revolution the carriage is first advanced, then the flames from the burners 15 are brought on to the tubes and finally the flames are removed and the chilling wheels are raised ; the cut lengths of tubing may be collected on wires inserted into the front ends of the tubes 10, each wire either leading to a suitable receptacle or having a handle by which it may be withdrawn when fully loaded. Chilling wheels.-These may comprise two contiguous mild steel discs having hard steel rims welded thereto, an intermediate boss projecting from one disc providing a groove wherein water is held by capillary attraction ; dimensions of a typical wheel are given. Their shafts 92, Fig. 1, are carried by spring-damped pivoted levers 93, Fig. 3, adjustably weightloaded at 95 and bearing against adjustable stops 96.

Abstract: Hard carbides of metals such as titanium, molybdenum, tungsten, &c. containing free carbon are formed by heating mixtures containing the finely divided oxides of the metals and an excess of carbon in a graphite cylinder, plugged at both ends, in a hydrogen furnace. Mixed carbides containing free carbon may be prepared by reducing, or oxidizing, double salts or mixed salts of the metals to produce alloys or oxides which are subsequently carburized.ALSO:A process for making hard cemented carbide material includes forming a hard carbide containing free carbon, mixing the carbide with a metal or metals of the group iron, cobalt, and nickel, and a metal capable of forming a hard carbide, or an oxide of such a metal, and sintering the mixture to decarbonize it in respect of free carbon.  Hard carbides containing free carbon are formed by carburizing metals or their oxides.  Mixed carbides may be formed by reducing or oxidizing mixed salt crystals or double salts to form alloys or oxides which are subsequently carburized.  The metal added for decarbonizing may be the same as or different from the metal of the carbide to which it is added.  The mixture may be hot pressed, or cold pressed and sintered twice at different temperatures.
