Title: Improved process and apparatus for applying coatings to surfaces
IPC: C23C14/26
Filed: 1934-04-13
Abstract: 436,792. Silvering. WALKER, C. H., Mabrouk, Lynmouth Avenue, Flixton, Manchester, SYKES, C., 2, South Meade, Timperley, Cheshire, and ASSOCIATED ELECTRICAL INDUSTRIES, Ltd., Crown House, Aldwych, London. April 13, 1934, No. 11220. [Class 93] [See also Groups II and XXII] Surfaces are coated with metal by distillation in a vacuum by placing the coating metal in the form of a thin uniform layer on the surface of a heater, preferably an electrically heated strip of tungsten or molybdenum, raising the temperature preferably slowly until the coating metal melts to form a thin uniform coating on the heater, and then raising the temperature to distil the coating metal on to the surface to be coated. The amount of coating metal placed on the heater is sufficiently small to ensure that any alloy which penetrates through the metal of the heater has a higher melting point than the distillation point of the coating metal. The vacuum is preferably high, the pressure being less than 10-<4> mm. of mercury. The process may be carried out in a vessel formed by securing a steel cylinder 1 in a vacuumtight manner to a plate 2 provided with an opening 3 to which is welded a tube 4 connected to a vacuum pump. In the upper part of the vessel is mounted a support 10 for the body 11 which is to be coated, which is introduced into the vessel through the top of the cylinder 1 which is then closed by a plate 6 secured to the vessel by vacuum-tight joints 9 which can be readily broken. These joints may be made of the grease or wax known under the Registered Trade Mark " Apiezon." A glass window 8 may be formed in the plate 6 or in the walls of the vessel. A heater strip 13 is held by clamps 14 secured to lead-in screws 12 passing through the bottom plate 2, and in operation a thin layer of metal powder is placed on the heater strip. The process may be used for coating glass, for example with aluminium to form astronomical and epidiascope reflectors, for coating presentation cups and other silver ware with aluminium, for coating paper, for example in the production of electrical condenser sheets or low current fuses, and for coating fibrous material such as textiles, silk, &c. Transparent surfaces with very thin coatings may be used as light filters. In coating large surfaces, two or more heaters may be used and coatings of alloys or mixtures may be obtained by using two or more heaters carrying different coating metals. In coating continuous lengths of paper, textiles, &c. a plurality of heaters may be mounted on a rotating or travelling member. The Provisional Specification describes the production of galvanometer leads in which a thick layer of silver is deposited on glass, cut into strips, and the thin strips then peeled from the glass. Specifications 346,293, [Group XXVIII], 360,826, and 407,503, [Group XXVIII], are referred to.

Title: Improvements in locking-ring rolling machine
IPC: B21H1/00
Filed: 1960-03-30
Abstract: 882,036. Sizing and restoring shape of locking rings; rolling; bending. KRADOSKA, E. C. March 30,1 960, No. 11252/60. Class 83 (4). In a machine for reforming a dented locking ring for clamping a closure to the open end of a drum, the ring is supported by a rotatable die 24, Fig. 2, and is acted upon by a pair of freely rotatable rolls, e.g. the rolls 33, 34 being movable towards and away from each other under the influence of springs, e.g. the springs 48<SP>1</SP>, 49<SP>1</SP> which exert a predetermined force and the rolls being moved into engage. ment with the ring by a second predetermined force. The rolls 33, 34 are carried on a pivoted support member 56 which also carries a second and similar set of rolls 31, 32, the member 56 being urged towards the die 24 by a pneumatic cylinder 60 and is also biased by springs 62 to a position wherein the rollers 31, 32, 33, 34 are equidistant from the axis of the die 24. The resistance of the springs 62 is such as to permit the supporting member 56 to tilt and yield to excess deforming pressure. The die 24 is rotated through somewhat less than 360 degrees in a first direction during rolling and is then reversed to rotate in the opposite direction, the oscillations continuing to remove a dent in the locking ring without permitting the passage between the rolls of fixing lugs on the ring. During the engaging of the rolls 31-34 the supporting member 56 is guided by movement of its pivot-pin 68 in a slot 70. When abnormally high deformation pressures arise the individual rolls of each pair move apart on pivoted arms, e.g. 39, 43 against the predetermined spring pressure. The spring pressure on one pair of rolls may be higher than that on the other pair, the ring being made to pass first between the rolls subjected to the lower pressure.
