Abstract: 809,674. Coating with metals. VAC ANSTALT. June 21, 1955 [July 27, 1954], No. 17947/55. Class 82(2) In a process and apparatus for vaporizing metals in vacuo, as for coating purposes, the metal is liquefied then atomized into a vacuum chamber (5) to form a mist (4) and the mist vaporized by radiant heat from heated high temperature bodies in or forming part of the chamber. The vaporizing process may be assisted by the setting up of a metal vapour discharge in the chamber between electrodes and passing the metal mist into the discharge. As shown liquid aluminium is vaporized at nozzle 1, which has a heating spiral 2 and preferably also cooling passages, and enters heated chamber 5 as a mist of droplets 4 which the heat converts into vapour which is withdrawn at slit 7 for deposition on a web e.g. paper, plastic, or textile material in a surrounding evacuater vessel, Chamber 5 may have an electron-emissive lining 6 of e.g. alkaline earth oxide, whilst annular electrodes 10, 11 with cooling or heating passages 12 may be used to set up the metal vapour discharge. The nozzle. may be connected to one electrode via switch 15 which should be opened once the discharge has begun. Several nozzles may be employed, and the atomized streams may be in various directions (Fig. 3, not shown). The vapour exit may be a slit (7) parallel to the length of the chamber, or helical, or may be an opening in the end of the chamber (Fig. 2, not shown), a suitable temperature for which chamber is 2000C. with an internal pressure of 1.5Î10<SP>-3</SP> to 1.5Î10<SP>-5</SP> atmospheres.

Title: Improvements in or relating to fluid-pressure operating devices for railway-carriage doors
IPC: E05F15/02
Filed: 1922-06-30
Abstract: 201,727. Baker, W. S. Graff-, and Moy, Ltd., E. F. June 30, 1922. Link-work.-For operating railway carriage doors the operating arms 12 pivotally attached to the door are mounted at 13 on a wheel or sector 1 adapted to be reciprocated by the piston of a cylinder 4, and rocked or oscillated by one or more chains encircling it and anchored to stationary parts. In the arrangement shown, the segment 1 has a chain 6 connected to it at 8 and at the other end to the frame of the device at 10. The chain 5 is attached at 7 to the lower part of the segment and at its other end to the stationary oylinder at 9. The segment is pivotally mounted at 2 on a pin carried by a piston of the operating cylinder 4. When the piston and pin are reciprocated, the chain members 5, 6 cause the segment and its lever members 12 to rock. In a cross-head 14 is mounted the bearing 15 for a pivotal connection with the door, and springs 16 allow the crosshead to yield in the event of an obstruction preventing the closure of the door. As the lever arms 12 move in the door-closed position, a projection 23 contacts with the lever arm 22 and a contact 19 engages members 18, thereby signalling that the door-closing operation is completed. The sector may be toothed to engage with the chains. If a complete circular wheel is employed instead of a sector, a single chain or cable may be used by looping it to encircle the wheel and anchoring its ends to stationary parts on the frame of the device. The pivot 2 is connected to a piston of the kind described in Specification 170,508, [Class 65 (i), Door and gate operating- appliances &c.].
