Title: Improvements in or relating to the production of strip metal
IPC: B22D11/06
Filed: 1952-05-22
Abstract: 736,310. Coating with metals; granulating. BRENNAN, J. B. May 22, 1952, No. 12994/52. Class 82 (2). [Also in Group XXII] Metal strip is made by feeding molten metal to an atomizer, depositing the atomized particles in a layer on a temperature-controlled base and then stripping the layer so produced. By means of lugs 10, a metal belt 9 is fed by a cogwhsel 22 and constrained by housings 11 so that it travels in two adjacent circular paths, Fig. 2. In one of the circular paths, the belt forms the outer wall of a chamber 6 in which a vacuum or inert atmosphere may be maintained and in which rotates an atomizing device 14 to which molten metal is supplied from a crucible 1 and by which metal particles are deposited on the belt to form a layer 21. The temperature of the belt is controlled by cooling sprays 23. Within the other circular portion of the belt, the layer 21 is stripped by a knife 20 and coiled at 19. In a modification, Fig. 3, molten metal is fed to an atomizer 36 and sprayed on to an aluminium roller 38 which is in contact with an anodizing bath 40 within a vacuum or inert atmosphere chamber 54. The deposited layer 37a is stripped, rolled at 43 and may then have another layer of the same or of a different metal sprayed on from an atomizer 47 as the strip passes a roller 44, the surface of the strip being first heated by induction heaters 55 and the deposited layer being annealed by heaters 55a. The strip then passes between sizing rolls 52 to a coiling device 53. The roller belt on which the metal is sprayed may have a surface of anodized aluminium, graphite, another metal having an oxidized or lubricated surface or a ceramic surface.

Abstract: 580,615. Screw pumps. SZCZENIOWSKI, B. July 7, 1944, No. 13047. [Class 110 (i)] A supercharger has two impellers 16, 17, on concentric shafts 26, 27, which rotate at different speeds, the speed of 17, preferably being greater than that of 16. Inlet guide vanes 26, may be moved as a whole, by a crank 22. Diffuser blades 23 may be provided in the outlet duct 12. The impellers may rotate in opposite directions.

Abstract: 366,823. Making stranded electric conductors. PIRELLI-GENERAL CABLE WORKS, Ltd., 144, Queen Victoria Street, London, and GIFFIN, G. W., Oakmount, Velmore Road, Chandlersford, Hampshire. May 5, 1931, No. 13308. [Classes 83 (ii) and 83 (iv).] Rolling.-Stranded non-circular, generally sector-shaped, conductors adapted to be combined in a multicore cable are formed by stranding wires to form a conductor of circular cross section, to which, by passage between rollers bodily revolved round the conductor in a plane at rightangles to it, a non-circular cross section and helical twist are imparted in a single operation. The wires are fed from a rotary carriage 1, through holes in a face-plate 2, to a die 3 where a stranded conductor of circular cross section is formed. The conductor thus formed is passed between rollers 4 which are carried on a rotating frame 5. The rate of travel of the conductor is determined by the winding on to a capstan 6 which is interconnected mechanically with the frame 5 so as to give the desired pitch of twist. Between the capstan 6 and frame 5 the conductor passes through paper-insulating heads 8. Specification 351,480 is referred to.

Abstract: 1,269,871. Automatic exchange systems. INTERNATIONAL STANDARD ELECTRIC CORP. 20 March, 1970 [21 March, 1969], No. 13560/70. Heading H4K. In a computer controlled PCM exchange a plurality of multisignallers are provided as interface units between the computer and the controlled devices of the exchange. Each instruction processed by a multisignaller is divided into numbered phases so that a check can be kept on the sequence of the phases, the number of the final phase providing an indication as to whether or not the computer should be immediately demanded to provide a new instruction or to process data gathered by the previous instruction. The multisignallers are connectible via special marking data lines to junctors so as to supervise their operation or via the switching network to the junctor or to other multisignallers or to trunks so as to exchange data therewith. The multisignallers' appearance on the network is exactly the same as the appearance of a highway super group or super junctor of the systems described in Specifications 1,261,599 and 1,269,888 to which attention is drawn for a description of the general operation of the system. The present specification is concerned wholly with the logic necessary to effect the operations of channel scanning for call detection, supervising reception of signalling data e.g. dialling, onward transmission of data, path search in the switching network, and modification of data in respect of setting up and breaking down a connection, these operations usually requiring more than one time frame for their accomplishment.

Abstract: 1,254,506. Lasers. WESTERN ELECTRIC CO. Inc. 17 March, 1969 [18 March, 1968], No. 13783/69. Heading H1C. A laser is mode locked and produces a continuous train of pulses by including a modulating reversibly-saturable absorption cell in the resonator, the cell being such as to absorb energy from a pulse of the radiation emitted from the active medium, and to return the energy to the pulse either once or twice for each two passes of the pulse through the cell. The absorption medium in the cell has discrete energy levels at least two of which are separated by approximately the photon energy of the laser radiation, and in the case of the He-Ne laser described neon is used as the absorption medium at a gas pressure equal to or less than a value providing a homogenous dephasing lifetime T 2 * greater than the line width. The absorbing medium also requires an energy storage lifetime T 1  greater than the pulse width 2L/Nc, L being the resonator length, c the velocity of light and N the number of longitudinal modes supported by the resonator. An absorption cell 31 which returns the energy absorbed in a single pass of a pulse is shown in Fig. 1, the cell being located in a resonator formed by a curved reflector 21 and a plane reflector 22 which reduces the beam width A 2  through the absorption cell to one half of the beam width A 1  through the active medium 12. Both the active and the absorption media are pumped by D.C. excitation from respective sources 19, 39 applied to electrode pairs 17, 18 and 37, 38, and both are contained in cylindrical tubes having Brewster windows 13, 14 and 33, 34. A modification is described, Fig. 2, in which both reflectors 41, 42 are plane and the beam width is halved by a lens system 61, 62. In Fig. 3 the absorption cell returns the energy absorbed after two passes of a pulse and in this arrangement the beam width is the same for both the absorption and active media, curved resonator reflectors 81, 82 being used. In a modification, Fig. 4 (not shown) a biconvex lens is included in the resonator.
