Abstract: 1,238,263. Welding by fusion; flame desurfacing. ESAB Ltd. 9 July, 1969 [11 July, 1968], No. 34658/69. Headings B3R and B3V. A butt-weld between members 5 of heavy sheet steel (5 mm. minimum thickness) is produced by one-sided consumable electrode arc welding using a steel backing strip 10 (2 mm. minimum thickness) welded to the members 5 but not fused through and is finished by removing at least most of the backing strip by a flame desurfacing process. In the apparatus shown, the members 5 are held in position by magnets (7) and are butt welded by two or more, simultaneously operated, or, as shown, a single electrode 26. A trolley 1 advanced at the same rate as the electrode supports a supply reel 9 from which the backing strip 10, of mild steel, is taken and held against the underside of the joint by grooved pressure rolls 18, 21, 19. The rolls 18, 19 are directly carried on a frame 17 supported on the trolley by hydraulic cylinders 11, 12. The roll 21 is aligned with the electrode and is carried on the frame 17 by way of a spring-pressed yoke 20 so as to accommodate linear deviations. A trolley traverse motor, gearing and motor control apparatus are provided in a housing 27 A selenium cell, supported on a housing mounted standard (29), senses heat radiation from part of the backing strip slightly in advance of the roll 21 and either controls the motor, so as to advance the trolley, continuously or discontinuously, to maintain the cell within a predetermined temperature zone of the backing strip, or, with a constant rate trolley advance, controls the welding current.  In alternative embodiments, the backing strip may be held against the work by one or more sliding pressure blocks or pads which may have coolant channels and may act as welding current contact members. The welding process may be submerged-arc, gas-shielded or mesh-encased flux-coated electrodes, or combinations thereof, e.g. gas-shielded root bead followed by submerged-arc. In the flame desurfacing process shown in Figs. 5, 6, a nozzle 37 is provided with a slotshaped orifice 35 for cutting oxygen and a number of circular orifices 36 for a pre-heating gas mixture of oxygen and acetylene. The desurfacing is preferably achieved in one pass and is such that the weld surface is practically flush or, preferably, the edge portions of the backing strip not welded to the work are removed whilst leaving a small portion of the backing strip in the form of a centrally positioned low ridge. The Specification includes details of opensquare and single-V (with root faces) butt-joints together with electrode diameters, bead numbers and welding currents, voltages and speeds therefor, and desurfacing oxygen orifice size and pressure and nozzle angle and advance speed.

Abstract: 1303243 Core constructions and winding layouts for dynamo-electric machines NATIONAL RESEARCH DEVELOPMENT CORP 25 Feb 1970 [24 March 1969] 15296/69 Heading H2A A three phase motor has a laminated stator core which is of polygonal shape externally and has a bore with slots of different depths, those of greater depth being adjacent the apices of the core and a double-layer winding with coils omitted from both top and bottom layers is distributed in the slots. Hexagonal or square laminations are preferred but triangular shapes may also be used. Fig. 5 shows a hexagonal lamination having two full-depth slots adjacent the apices and four half-depth slots adjacent the sides and Fig. 4 shows the layout of a threephase 4-pole winding in 36 slots suitable therefor. The upper layer is combined with one of the lower layer alternatives (a), (b) or (c) to form the complete winding and six equally-spaced groups of coils, shown "boxed", are omitted from the initial layout. It will be seen that alternative (c) provides four half-empty slots in six equidistant places and is therefore the most convenient. Other three-phase arrangements shown include a six-pole winding in square laminations having three full-depth slots adjacent each corner and six half-depth slots between, and an eight-pole winding for hexagonal laminations. Concentric coils may be used in some windings (Figs. 13 and 14, not shown) and the windings may be adapted for speed-changing by P.A.M. If the winding design would involve leaving some slots empty, these slots may be omitted from the laminations.

Abstract: 1315117 Coated hose GEORGE ANGUS & CO Ltd 15 July 1970 [4 June 1969] 28212/69 Heading B2E [Also in Divisions B5 and F2] A method of making a hose comprises applying an unvulcanised elastomeric lining tube, e.g. of synthetic rubber, to a mandrel, covering the lining tube with a braided, knitted, woven or lapped reinforcement, vulcanising the lining tube after application of the reinforcement, and then applying an unvulcanised outer thermoplastic cover before removing the mandrel. The lining tube may be of nitrile rubber and may be extruded onto the mandrel, which may be of flexible nylon. The lining tube may be rigidified by freezing before applying the reinforcement, e.g. by a machine which braids brass-plated wire. The assembly is then passed continuously through a fluidised-bed vulcaniser. The outer cover may be of nylon, polypropylene or polyethylene extruded around the assembly or applied by spray or hot melt technique. Alternatively, the outer cover may be of rubber in which case a further vulcanising treatment is carried out. The reinforcement bonds to the lining tube and may be bonded to the outer cover using a blend of polyamide and epoxy resins.
