Title: Improvements relating to the Coating of Metals.
IPC: B05D3/02
Filed: 1966-12-21
Abstract: 1,173,584. Coating metals. HUNTER DOUGLAS-INTERNATIONAL Ltd. 21 Dec., 1966 [4 April, 1966], No. 57286/66. Heading B2K. Tin or tin plate, or metals or alloys having an analogous behaviour with regard to melting and crystallization properties is coated with a layer of lacquer and quickly heated to a temperature above the melting point of the tin or other metal or alloy to cure the lacquer layer and simultaneously cause the surface metal or alloy layer temporarily to melt, and thereafter the material is cooled to a lower temperature, the heating time and temperature being such that the surface layer of the metal or alloy reaches an obviously molten stage before becoming resolidified. The resin may be cured at 300‹C. for 40 seconds, and the material then cools in water at 70 to 75‹ Centigrade. The heating temperature and heating period are chosen such that the molten metal or alloy does not drip away or have its adhesion to an underlayer impaired. The speed of cooling such that after its recrystallization the metal or alloy does not have an undesired crystal structure. The method can be carried out continuously as well as discontinuously. The material can be coated on one or both sides. In example 1 tin plate is lacquered with a white epoxy resin to a layer thickness of 8 to 10 microns. The epoxy resin is then cured at 300‹ Centigrade for 40 seconds, and the material is cooled in water at 70 to 75‹ Centigrade.

Abstract: 1,163,109. Electrical heating. METALLWERK PLANSEE A.G. 21 Dec., 1966 [21 Dec., 1965], No. 57297/66. Heading H5H. A heating element is made from one or more tubular conductors which are fabricated to form a hollow cylindrical shape. Each conductor is made from individual wires by braiding or cabling, Figs. 1-3 (not shown) to produce a tubular form and, in general, the wires may be from 0.01 to 0.3 mm. in diameter, made from, e.g. tungsten, molybdenum, tantalum or nickelchromium, while the resultant conductor may be 2 mm. or more in diameter. Such conductors are woven or otherwise associated to produce a fabric 1, Fig. 5, which shows a heating element in which two rectangular pieces of such fabric are curved to semi-cylindrical form and welded to a common conducting ring 4, at one end, and to individual terminal elements 5, 6 at the other end. In a further form of heating element, Fig. 6, a single tubular conductor 8, of 5 mm. diameter, is looped repeatedly to form a cylindrical shape 7 and supported by binding to ceramic rings 10. Three input cables 11 are attached to the looped conductor at points mutually spaced by 120 degrees for the supply of three-phase current. The arrangement may be suitably modified to provide a star connection.

Patent GB-710492-A (GB)
Abstract: 710,492. Calculating-apparatus, BROIDO, D. Dec. 13, 1951 [Jan. 2, 1951], No. 175/51. Class 106 (1) Differential mechanism in a calculating machine comprises reciprocating members which are driven onto stops, differentially arranged in accordance with a number to be entered, through a part of the stroke corresponding to one unit positively and are positively restored. In the machine described, an extra unit is entered into each order and transfer mechanism such as described in Specification 710,493 is employed to enter a unit reversely in each order which is not to receive a transfer unit. For addition, wheels 27 couple each of a set of reciprocating racks 20 with an associated gear 17 meshing with a totalizer pinion 15 during the forward stroke of the racks towards the stops. In subtraction, the wheels 27 couple the racks and gears 17 as the racks are restored. The wheels 27 are mounted in a cam-controlled frame, the timing of their engagement being determined by the direction of rotation of the mainshaft. The racks are normally positioned one step from the zero stops so that transverse movement of the stops is unhindered, and are moved through this step positively by a bar 170 mounted between camcontrolled arms rockable about a shaft 81. The bar 170 rapidly accelerates the racks so that springs 19 which urge the racks against the stops can be relatively weak or even absent. The bar 170 may normally be spaced away from the racks so that when it strikes them it will already have accelerated. A fixed stop prevents overthrow of the bar 170. The racks are released for forward movement and later restored by a bar 25 mounted between cam-controlled slides. A pawl 171 co-operates with each rack to prevent rebound. Projections 198 on the bar 25 rock a frame 191 as the bar completes its forward movement to disengage the pawls for the restoration of the racks, the frame being latched by a lever 193 until the end of the cycle when the lever is rocked by a cam stud 197. Specifications 577,330 and 687,582 also are referred to.
