[Class 100 (i)] Sheet-separators.-In a sheet-feeding device for printing-presses &c. of the kind in which a long suction member 8 fitted with apertures 9 is moved to and from a pile and the separated sheet is seized by other members which forward it to the press, the suction member 8 is carried by links 7 and is given a swinging movement so as to bend the edge of the sheet as shown by means of a piston 13 working in a cylinder 12 connected by a pipe 19 to the suction member 8. As soon as the air pressure is reduced sufficiently to cause the edge of the sheet to adhere to the apertures 9, the piston 13 moves to the right and by means of a link 15 swings the links 7 clockwise. The arms 4 in which the links 7 are pivoted are subsequently raised by links 5 in order to complete the separating action. When the vacuum is released the piston 13 returns to the left, and the arms 4 return so as to bring the member 8 into contact with the pile. The member 8 is fitted with projections which engage the ends 11 of the arms 4 to limit the pivotal motion of the member 8.

Filed: 1974-03-22
Abstract: 1453750 Steam turbines STAL-LAVAL TURBIN AB 22 March 1974 [23 March 1973] 12774/74 Heading FIT [Also in Division G3] A steam turbine control system comprises a hydraulic source HT which normally supplies control liquid via valve 4 and throttle 1 to the actuator 10 of steam valve 8. Rapid closing of the latter under the action of spring 11 is effected by opening valve 2 to vent actuator 10 to drain. The resulting fall in control pressure downstream of throttle 1 is communicated to the actuator of valve 4 via a line passing through valve 5, causing valve 4 to move to a position in which it blocks the source HT and simultaneously vents a further servosystem R normally supplied from source HT and controling conditions such as steam pressure, rotational speed and power. Steam valve 8 can be reopened by closing valve 2 and briefly switching valve 5, so that the source HT is connected via throttle 6 to the actuator of valve 4, causing the latter to be restored to the normal position shown. When the control pressure downstream of throttle 1 has reached its full value, valve 5 is switched back to the position shown. A slightly modified control circuit is illustrated in Fig. 2 (not shown).

Title: Semiconducting material and method of manufacture and use thereof
IPC: H01L35/22
Filed: 1972-03-20
Abstract: 1377413 Coated Al 2 O 3  and Al 2 O 3 -SiO 2  UNIVERSAL OIL PRODUCTS CO 20 March 1972 12865/72 Headings C1A and C1J [Also in Division H1] A semi-conductor material is produced by exposing a refractory oxide at a temperature in the range 400-1000 C. to the vapour of an organic pyrolysable compound to thereby form at least a monolayer of a carbonaceous pyropolymer on the oxide. The only oxides specified are alumina (γ-alumina) and alumina-silica but the organic compounds suggested are virtually unlimited (and include metal salts and organometallic compounds). The physical forms permissible for the oxide are numerous. Catalysts (for the pyropolymerization) or dopants may be pre-impregnated into the oxide; platinum, rhenium, germanium, nickel, and combinations of either of these metals with tin or lead are mentioned in this connection as is also sodium chloride. The pyrolysis may be carried out in either an inert or a reducing atmosphere. The carbon content of the pyropolymer covers and may extend beyond the range 9-30 wt. per cent. The semi-conductor may show pyroelectric, ferroelectric, piezoelectric, or thermoelectric properties; and may have a low coefficient of friction. The last property is obtained by pressing the semi-conductor harder with a dry lubricant such as molybdenum disulphide or antimony oxide and makes the material of use for switch contacts and for brushes in motors and generators. The semiconductor (which may be produced in P and N types) may be used as the body of an IGFET (Fig. 3, not shown); as thermoelectric elements in generators or refrigerators; as inductors (using the piezoelectric properties in a zeries tuned circuit operated at above the resonant frequency); as electrodes in electrochemical cells, charge and energy storage devices; as memory devices; as temperature sensors; and in heterojunction transistors. The materials used in the twelve specific examples are γ- alumina doped with platinum and reacted with cyclohexane, pyridine, or n-pentane; spheres of γ-alumina reacted with benzene, cyclohexane, ethene, or carbon tetrachloride; γ-alumina doped with sodium chloride and reacted with cyclohexane (the material is N-type and strongly pyroelectric); silica-alumina spheres reacted with cyclohexane, ethanol, or methyl propyl sulphide; and faujasite reacted with cyclohexane. The treatment apparatus (Fig. 1) directs a vertical vapour stream downwards over a quartz chip preheater 12 and then over the refractory oxide 10, the reaction tube being gas heated.

Abstract: 528,202. Phenol-formaldehyde and molten products. BRITISH THOMSON-HOUSTON CO., Ltd. April 29, 1939, No. 12883. Convention date, April 29, 1938. [Class 2 (iii)] A liquid coating and impregnating composition is produced by reacting a phenol and an aqueous solution of an excess of formaldehyde, with ammonia or an amine as catalyst, at a temperature not exceeding 60‹C. for a period sufficient to effect separation of an oily layer which contains not more than 75 and not less than 60 per cent. by weight of potentiallyactive resin, withdrawing the oily layer and incorporating therewith a water-miscible organic solvent liquid in an amount effective to prevent separation of water. The molecular ratio of formaldehyde to phenol may be 1.05-1.5. Phenol includes cresol, xylenols and phenolic homologues and derivatives having at least one hydroxyl group. In place of formaldehyde, paraformaldehyde or a compound yielding formaldehyde. Specified amines are hexamethylene tetramine, methylamine, ethylamine, ethylene diamine and triethylene tetramine. An example is given of the preparation of a resin varnish from cresol, formaldehyde and ammonia separation of water from the resin being effected by an addition of 5-20 per cent. of methyl or ethyl alcohol, acetone or of a mixture of equal parts of alcohol and benzene. The varnish may be used to impregnate fibrous material e.g. paper or cloth, for the production of laminated sheet material. The Specification as open to inspection under Sect. 91 describes also an alternative process in which the reaction mixture is stabilized, without separation of resin, by adding an emulsifying agent, e.g. a gum or clay. This subject-matter does not appear in the Specification as accepted.

Abstract: 841,507. Refrigerating. DUNHAM-BUSH Ltd. April 23, 1958 [April 25, 1957], No. 12951/58. Class 29  In a compression system having between the compressor 2 and the condenser 12 an oil separator 24 from which oil is returned to the compressor through a pipe 8, an orifice 84 is provided in pipe 8 of such size as to readily pass oil but, in the absence of oil, as to prevent any substantial flow of refrigerant'gas due to a "pressure shock" condition. The Specification quotes particular sizes of orifice for different capacities of plant. As shown, mixed oil and gas flow into the separator through peripheral apertures 42 in a closed ended cylinder and then through a screen 36. They then flow through a nozzle 48 in a transverse wall 44 and impinge on a cupshaped member 54 carried by an arm 56 pivoted at 60. Movement of the arm 56 opens valve 75 in series with the orifice 84 and any oil flows through the valve, a screen 92 and orifice 84 to the compressor. If no oil be present, no substantial gas flow occurs through the orifice. Refrigerant gas flows through a further screen 93 before entering the condenser. Transverse wall 44 may have auxiliary apertures 50, 52. Arm 56 may be pivoted about a vertical axis and biased towards nozzle 48 by a spring. The separator also acts as a muffler for compressor noise.
