Title: Production of elastomeric polymers from 1,3-dienes
Inventor: MUELLER HERBERT
IPC: C08F36/04
Filed: 1962-05-03
Abstract: Elastomeric polymers are produced by polymerising a 1,3-diene using a catalyst prepared from a mixture of metallic cobalt and/or nickel with an aluminium halide.  The diene may be butadiene, isoprene, 2,3-dimethyl-butadiene or chloroprene. A cyclic olefine having more than one double bond, e.g. cyclododecatriene-1,5,9, cyclooctadiene-1,5, or cyclooctatetrane, and/or a substance which forms complexes with aluminium halides, e.g. ethers, amines such as N-phenyl-8-naphthylamine, salts of alkali and alkaline earth metals such as NaCl, thioethers, phosphines, arsines or stibenes, may be used as co-catalysts. The halide may be AlCl3 or AlBr3, and may be used together with the cobalt or nickel in powdered form.  Raney nickel or cobalt, or alloys containing these metals may be used. The diene may be mixed with substances inert during polymerisation, e.g. butane or butene, which may be carried out in a solvent, e.g. hydrocarbons, or in bulk continuously or batchwise. The catalyst may be destroyed after polymerisation by addition of water or methanol, e.g. after precipitating with hydrogen sulphide. The transparent polymers may be used for car tyres.

Abstract: 919,022. Magnetic storage devices. GENERAL ELECTRIC CO. Ltd. May 28, 1959 [May 29, 1958], No. 17014/58. Class 38 (2). A magnetic thin film 1 is switched by domain rotation by concurrent pulses in conductor loops 10a, 10b and 1 1a, 11b, the former producing a field along the easy axis of magnetization PA which is too small to cause domain wall movement. The field, perpendicular to the axis PA, produced by loop 11a 11b is in excess of 0.6 of the magnitude of the field needed to saturate the film 1 in that direction and is terminated by cessation of the pulse producing it before the field produced by loop 10a, 10b along the axis PA, is terminated. Destructive or non-destructive read-out is effected by a pulse in loop 1 1a, 11b, the polarity of the first or second pulse produced thereby in the pick-up loop 9a, 9b being detected for that purpose. Loop 9a, 9b may be dispensed with. The device may be manufactured by the method described in Specification 919,021. According to the Provisional Specification single conductors may be used, read-out being by switching of the film along its easy axis. Also, the current producing the field perpendicular to the easy axis may be continuous, being interrupted for sensing purposes.

Title: Improvements relating to axial-flow compressors
IPC: F04D29/52
Filed: 1957-06-05
Abstract: 810,180. Axial-flow compressors; gas turbine plant. GENERAL MOTORS CORPORATION. June 5, 1957 [June 18, 1956], No. 17877/57. Classes 110 (1) and 110 (3). In an axial-flow compressor the cross-sectional area of the intake passage is varied by an annular row of flaps pivotally attached to the inner wall of the passage and movable from a position in which they are substantially flush with the wall to positions in which they extend across the passage, the pivotal attachment of each flap being by a link pivoted at one end to the flap and at the other end to the wall. In the axial-flow compressor shown, forming part of a gas turbine engine, the annular intake is divided into four segments by four radial struts 14. Within each segment the inner wall 12 is cut away to form a recess 22 in which five pivoted flaps 38-normally lie flush with the wall 12, as shown dotted in Fig. 2. The flaps 38 can be moved from the flush position to the position shown, in which they partially obturate the intake. For this purpose, a segmental member 24 is provided with each segment and is provided with five lugs 30, to each of which a flap 38 is pivoted at 42. A pivoted link 44 connects each flap 38 to a further lug 48 secured to a housing 56. Each member 24 is movable in an axial direction by a pair of piston rods 84, each of which is slidable in a cylinder 72. To extend the flaps 38, hydraulic operating fluid is admitted to each cylinder 72 through a connection 112 and acts on a piston 92 to move the piston rod 84 into the position shown, hydraulic fluid trapped in the cylinder on the opposite side of the piston being drained through bores 100, 98 and a connection 110. To return the flaps 38 to the flush position, connection 110 is connected to the hydraulic supply and connection 112 is connected to the drain. Each member 24 is slidably mounted on two guide rods 122. Alternatively, each piston rod 84 may have an extension which slides within a bore provided in the compressor casing structure. The flaps 38 may be movable to a position intermediate between the flush and fully extended positions. The flaps may be interconnected by a flexible bellows or sealing member to form a continuous wall. Hot air, bled from a later stage of the compressor or from the turbine, may be passed through passages within the links 44 and discharged over the inner or outer surface of each flap 38 to prevent formation of ice.

Abstract: 458,820. Directive wireless signalling. HONEYBALL, L. L. K., Newgardens, Teynham, Kent. June 22,1935, No. 17941. [Class 40 (v)] A direction-finding system depends on the changes of current in a fixed tuned vertical aerial when the position of a similar but electrically unconnected aerial changes relative thereto. As shown, a fixed aerial R is connected to a receiver and a mobile aerial is moved round circles centred at R and having radii equal to 0À16#, 0À33#, 0À60#, 0À71# and 0À85#. If O is the distant transmitter, the receiver will indicate a maximum current in the aerial R when the mobile aerial is at the positions C on the first circle, D on the second, X and Y on the fourth. and F on the fifth, while a minimum is registered when the mobile aerial is at the point E on the third circle. The line FEDRC indicates the direction and " sense " of the transmitter O while the line XRY indicates a direction perpendicular thereto. A check may be made by moving the mobile aerial along the bearing line. Five movable aerials may be employed with means for disabling those not in use at any moment. In order to record the directions of the points C, D, E, F, X, Y, a sighting device may be arranged to swing over a compass card at the position R and a trigger which when operated makes a mark on the card. A light rod or cord may join the aerials to maintain their correct distance and give a direct reading of the bearing. The received signals may operate a visible or audible signal in the " maximum " positions or a relay for marking the compass card automatically.

Title: Method of coating electrically conductive components
IPC: C23C14/24
Filed: 1978-05-05
Abstract: The article (1) made of carbon steel and the chrome-iron plate (14) form cathodes arranged facing the anode (8) in the vessel (2). They are connected to electrical generators (5, 12). A dynamic pressure of the order of 3 torr is maintained in the vessel (2) using the pump (6), the atmosphere consisting of argon. Since the potential differences between the anode and the cathodes are from 450 to 500 V and 600 V, the cathodes are subjected to a bombardment with positive ions. The abnormal luminescent discharge established between the electrodes gives rise to the deposition of a layer of alloy of high chromium content on the article (1). In the second stage of the treatment, diffusion of carbon from the article (1) into the layer is produced, and this gives a chromium carbide layer. <IMAGE>
