Filed: 1957-01-04
Abstract: A semi-conductor material comprises bismuth telluride containing lithium as a donor impurity.  In one embodiment bismuth and tellurium and an alloy of bismuth with 0.2% by weight of lithium are mixed together in such amounts that the mixture contains stoichiometric proportions of bismuth and tellurium and an amount of lithium equal to 0.025% by weight of the mixture as a whole.  The mixture is placed in a cylindrical silica bomb which is then evacuated to 10-5 mm. of mercury, sealed, and heated for at least 3 hours at 900 DEG  C.  The product is then melted by induction heating in a silica boat in an inert atmosphere and thus formed into an ingot which is subjected to single pass zone melting in a flow of inert gas at atmospheric pressure.  The resulting material is of N-type conductivity, has a resistivity of about 1 milliohm cm. and a thermoelectric power of 170 microvolts/ DEG  C.  This bismuth lithium alloy used in the above process is prepared by melting bismuth with 0.2% by weight of lithium in a silica boat at 500 DEG  C. for several hours in an atmosphere of argon.ALSO:An alloy used in the preparation of semiconductive bismuth telluride (see Group XXXVI) comprises bismuth containing 0.2% by weight of lithium.

Abstract: 1,135,901. Rollers. MOUNT HOPE MACHINERY Ltd. 4 Jan., 1967 [20 May, 1966], No. 519/67. Heading F2U. [Also in Division D2] In a roller comprising a cylindrical sleeve 10 of hard rubber or glass fibre rotatably supported on an axle 28 by at least three axially spaced apart bearings 20, 22 with spools 14, 18 supporting the sleeve between the bearings, at least one of the bearings is adjustable radially of the axle to eliminate longitudinal curvature of the sleeve 10 when the axle 28 bends under load. In the roller shown, for supporting the travelling wire mesh 12 in a paper-making machine, rigid collars 24 support the end bearings 20 on the axle 28. The intermediate bearings 22 are each supported by shoes 36, 38 pivoted to pistons 40, 42 extending from radial bores 48 in a block 46 secured within the axle. Individual lines 50 connect the bores 48 to closed bellows 52 at the end of axle 28. The bores 48, lines 50, and bellows 52 are filled with fluid, and screws 54 are turned to adjust the capacity of respective bellows, and hence the radial position of each piston. Each symmetrically spaced pair of bearings, and any odd bearings, will require individual sets of lines 50 and control bellows. With the roller normally loaded, the pistons 40 adjacent the mesh 12 are first adjusted to straighten the sleeve 10, the other screws 54 being slackened previously. Then the remaining pistons are adjusted to bring the remaining shoes into contact with the bearings. In Fig. 3 (not shown) elastomeric bags replace the shoes, pistons, and bores 48. In Figs. 4, 5 (not shown) the shoes (36, 38) are pivoted to tappets (70, 72) engaging cams (76, 74) respectively. Cam (76) is symmetrical about its axis of rotation, to move shoes (38) normal to the direction of the applied load on the roller. Cam (74) is asymmetric to its axis of rotation, to control the straightness of the sleeve. Individual shafts (78, 80) control the cams.

Title: Selective hydrogenation of acetylene in ethylene
Inventor: FREVEL LUDO KARL
IPC: C07C7/167
Filed: 1957-01-07
Abstract: A catalyst containing not more than 5 per cent by weight of a metallic mixture of 60 to 99 parts by weight of palladium and 40 to 1 part of copper, silver, or gold disposed on a catalytically inactive carrier such as pumice, inactive alumina, diatomaceous earth, asbestos, coke or charcoal, is used in the selective hydrogenation of acetylene in the presence of ethylene (see Group IV (b)).  The catalysts are prepared by treating the support with aqueous solutions of soluble salts of the metals which salts can be decomposed at temperatures below 500 DEG  C., drying the mixture, roasting in air at 325-500 DEG  C. to convert the metal salts to the oxides and reducing to the metal in hydrogen at 25-450 DEG  C. Specified salts are palladium nitrate, cupric nitrate, silver nitrate and chlorocuric acid.  The catalysts are gradually inactivated by the deposition of carbonaceous matter and are readily reactivated by burning off the deposits by oxidation at, e.g., 400 DEG  C., followed by reduction of the catalyst in hydrogen.ALSO:Acetylene is selectively hydrogenated in the presence of ethylene by contacting the mixture together with more than one mol. of hydrogen per mol. of acetylene with a catalyst containing a metallic mixture containing 60 to 99 parts by weight of palladium and 40 to 1 part of copper, silver or gold (see Group III). The feed is preferably desulphurized, e.g. by passing through basic lead acetate.  Temperatures of room temperature to 250 DEG  C. are used at above, below or at atmospheric pressure.  A typical example illustrates the hydrogenation of acetylene in a gas stream produced from a commercial gas cracking plant consisting mostly of ethylene with small amounts of acetylene (3-4 volume per cent) methane, carbon dioxide and air.  Hydrogen is added and the gas passed over a catalyst containing 0.2 per cent palladium and 0.01 per cent silver on diatomaceous earth at 100 DEG  C. and 50 p.s.i.g.; the product stream is free of acetylene.

Abstract: 861,116. Cold-cathode tubes. HIRAC Ltd. April 4, 1957 [Jan. 9, 1956], No. 713/56. Class 39(1). In a gas-filled electric discharge tube of the trigger type comprising a cathode electrode, an anode electrode, and a separate trigger electrode by means of which an auxiliary discharge may be set up to initiate the main discharge, a member which is insulated from said electrodes is arranged to be movable within the tube into and out of the path of said auxiliary discharge by means external to the tube for the purpose of modifying the trigger-discharge characteristic of the tube. In the tube shown a thin sheet of mica 8 connected to an armature 9 of magnetic material obstructs the discharge between a small metal plate trigger electrode 6 and the straight edge of a part-annular plate cathode 5 surrounding a rod or wire anode 1 which is also surrounded for the greater part of its length by an insulating sleeve 2. Leads (not shown) to the anode 1, cathode 5 and trigger electrode 6 pass through a thickened pinch of the envelope 4 which is preferably moulded integrally with the insulating sleeve 2. The armature 9 is mounted on a flexible member such as a thin wire of spring material secured in the pinch and can be moved to the position shown in dotted lines by supplying current to an external magnet coil 11. In an alternative embodiment (Figs. 3 and 4, not shown) the mica plate 8 and trigger electrode 6 are mounted in planes parallel to that of the cathode and overlying a region near the straight edge thereof, and the mica plate is moved in a radial direction with respect to the anode 1. In either embodiment the envelope may be of square section to enable the coil 11 to be brought closer to the armature 9, and the mica sheet 8 may be moved from a non-obstructing position to an obstructing position. The mica plate 8 may be replaced by a conductive member in the form of a short metal rod or a sphere which decreases the effective discharge path length between two of the tube electrodes. The movable member may have three or more control positions, the selection which depends on the current in the coil 11, or a plurality of movable members may be employed in a single tube and operated by a common or individual external control.
