Title: Method of manufactur9ng targets of pickup tubes
IPC: H01L21/06
Filed: 1974-09-10
Abstract: 1460339 Image pickup tube; photoconductive targets HITACHI Ltd 10 Sept 1974 [10 Sept 1973] 39353/74 Headings H1D and H1K [Also in Division C7] To form a pick-up tube target comprising a substrate 1 carrying an N-type light transmitting photoconductive film 2, a first photoconductive layer 4 of II-VI compound is vacuumevaporated from a boat 9 in apparatus including a hollow shield 8, with the substrate heated 11 to between 50‹ and 250‹ C.; a further amorphous P-type photoconductive layer 3 of substantially metallic Se being then applied. CdSe is one suitable II-VI compound, others being CdS, ZnS, ZnSe; the boat 9 made of, e.g. Pt, Ta, Mo is either protected by an inert coating or should be preheated with the compound for an hour at 350‹-500‹ C. to prevent variation of crystallinity of the deposited thin layer 4 and subsequent instability of dark current. The heating of the substrate during deposition minimizes the generation of defects. The Se layer 3 following prior art may be doped with Te and As.

Title: Method of handling and collecting record tags preparatory to mechanical evaluation
IPC: B41K3/68
Filed: 1960-11-16
Abstract: 918,998. Record card apparatus. BRENNINKMEYER G.m.b.H., C. & A. Nov. 16, 1960 [Nov. 21, 1959], No. 39355/60. Class 106 (1). Two-part record tags of the kind, attached to goods sold in a shop, are prepared for the sensing machine, in a machine, Figs. 1, 2, in which of the tags are severed and one part of each collected in a box 11, a threading device having rods 71, Fig. 8, being passed through holes 22 in the collected tags to remove them from the box and place them in the feed hopper of a sensing machine. The tags are placed in a stirrup 1 of the machine which is then displaced inwardly against spring 63, a lever 14 tripping plunger 24 to bring a plate 23 down on the record. The tag is aligned by pins 21 on plate 23 engaging holes 22. If the tag is incorrectly placed the plate cannot come down to the position in which a switch is closed to start the machine. Operation of the machine is thereby prevented. When the machine starts a cutting plate 36 descends by operation of camshaft 55 and severs the tag by co-operation with an edge of the bottom plate. The part of the tag under the cutting plate passes into the box 11 having been impressed during cutting by a stamp 44 indicating the cashier responsible for the sale. A stamp 43 simultaneously marks the other part of the tag " paid." The stamp 44 is removable and the machine is locked in its absence. At the end of a day's working the box is closed by a sliding cap 70, Fig. 8, and removed. To prepare the tags for the sensing machine they are engaged on the rods 71 of the threading device and after turning the whole assembly over the box is withdrawn, leaving the tags on the rods 71. The top tag is a special tag which was put into the machine first to identify the salesman. When the stack is placed in the feed hopper of the sensing machine, Fig. 10, a sliding weight 73 keeps the tags pressed down to facilitate separation by blade 75.

Catalyst formation may be in situ in the vessel and in an inert solvent suitable for use in the polymerization, e.g. hexane, cyclohexane, dimethyl cyclohexane, octane, gasoline, benzene, xylene, toluene, carbon tetrachloride and mixtures thereof.  The yield and molecular weight of the polyolefins may be altered by varying the temperature, the pressure, or the molar proportions of the catalyst components. The products may be obtained in granular form and may be purified with organic solvents or dilute aqueous or organic solutions of acids, e.g. aqueous or methanolic hydrochloric acid.  The high molecular weights of the polyolefins may be reduced by boiling with 30 to 40 per cent nitric acid.  Examples illustrate the continuous addition of ethylene during the polymerization.

IPC: H01L29/00
Filed: 1958-12-12
Abstract: 938,911. Semi-conductor rectifiers. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Feb. 24, 1960 [Dec. 12, 1958], No. 40189/58. Class 37. A semi-conductor rectifying diode, in which the tip of a conductor is in rectifying contact with a surface of semi-conductor material, is made by embedding the conductor in a body of vitreous material so that at the tip the conductor forms an angle with the surface of the body at which the tip is exposed, and depositing or forming a layer of semi-conductor material on said surface, ohmic contact then being made to said layer. In Fig. 1, a conductor 2 of copper, molybdenum, tungsten, " Kovar " (Registered Trade Mark) &c. of diameter 0.001 inch or less, is embedded in a body 1 of glass, one end of the conductor extending through a surface 3 of the body normal to the conductor, which surface is then ground and lapped to expose a small area of the conductor coplanar with the surface. Alternatively, the conductor may be of greater cross-sectional area and pointed at the surface 3; or molten metal may be introduced into a fine hole in the glass body; or metal foil, or a deposited layer of, e.g. gold, molybdenum, tungsten, may be sandwiched between two plates of glass which are then fused together. The last method is used in the multiple junction device shown in Fig. 3 which may be used in a waveguide, in which the conductor 2 is a serrated foil, the serrations of which extend to the edges of the glass plates, the common surface of which may be ground. A layer 4 of semi-conductor material is then deposited on the surface 3; e.g. a layer of selenium may be evaporated on to the surface, or a layer of germanium may be deposited by heating germanium iodide to 400‹ C. The layer 4 may be restricted to an area surrounding and covering the tip. A metallic layer 6 of, e.g. tin or indium, is deposited over the semi-conductor layer 4 to form an ohmic contact therewith ; it may completely overlie the layer 4, thus forming a protective coating therefor. germanium may be deposited by heating germanium iodide to 400‹ C. The layer 4 may be restricted to an area surrounding and covering the tip. A metallic layer 5 of, e.g. tin or indium, is deposited over the semi-conductor layer 4 to form an ohmic contact therewith; it may completely overlie the layer 4, thus forming a protective coating therefor.

The ore may be given an initial magnetic separation and the non- magnetic fraction used as starting material. Before either leaching stage, and/or any preliminary leaching, the ore may be heated with coal, charcoal, anthracite, coke, H 2 , CO, or H 2 +CO, to reduce Fe<SP>3+</SP> to Fe<SP>2+</SP>. The second leaching may be effected by recycling the magnetic fraction and mixing with the ore. The ore may be sand or ground massive ore and preferably has a particle size of 20-200 mesh. The acid may be H 2 SO 4  or HCl, or waste acid, e.g. sulphate process or pickling acid. Leaching may be effected in the presence of colloidal hydroxides of Ti, Sn, Nb, Ta, or Si (which may be formed in situ from, e.g., Na stannate or silicate), Ti<SP>3+</SP> salts (formed, e.g., by adding powdered Fe), or F ions, e.g. HF, NH 4 F, or CaF 2 .

Abstract: Gentiobiose and D-glucose are obtained by treating a 1% aqueous solution of scleroglucan (a 1,3-beta-linked polyglucose having 1,6-beta-linked glucose units with beta 1,3-D-glucanase. Acid hydrolysis of polyglucoses is also referred to.ALSO:A water-soluble polysaccharide has the structure <FORM:1061043/C3/1> wherein X1, X2 and X3 are hydrogen or substituted glucopyranose units having the structure <FORM:1061043/C3/2> and Y is OH, OR, OOCR, OCH2COOH, OSO3M, ONO2, OCS2M or OOCNH#j, where R is an aryl group or an alkyl group having 1 to 8 carbon atoms, and M is hydrogen or a cation, and wherein at least one of X1, X2 and X3 is other than hydrogen.  The polysaccharide consists of a 1,3-beta-linked D-glucose polymer bearing 1,6-beta-linked D-glucose units.  The polysaccharide is made by inoculating an aqueous solution containing a carbohydrate source with a micro-organism and fermenting the inoculated solution, preferably in presence of yeast extract or a mineral salt.  The micro-organism may be Schlerotium glucanicum (NRRL 3006) or other species of Sclerotium, Corticium, Stromatinia and Sclerotinia.  The polysaccharide may be isolated by precipitation with organic solvent, and is designated scleroglucan when produced by Sclerotium glucanicum. Scleroglucan forms aqueous gels, the viscosity of which is stable at varying pH. Examples describe the preparation of Scleroglucan xanthate, scleroglucan methyl, carboxymethyl and benzyl ethers and scleroglucan acetate, benzoate, sulphate and carbanilate.ALSO:A standard chiffon cake formulation, and a standard marsh-mallow-like cake frosting formulation contain the polysaccharide scleroglucan (a 1, 3-beta-linked polyglucose having 1, 6-beta-linked glucose units).
