Abstract: 1373508 Welding by pressure; jointing KERNFORSCHUNGSANLAGE JULICH GmbH 16 Nov 1971 [10 Dec 1970] 53143/71 Headings B3R and B3V In joining two workpieces of different melting points, at least one projecting portion and recess being provided on the bonding face of the first workpiece which has the higher melting point, the workpieces are heated and pressed together so that the first workpiece remains solid but the other workpiece flows plastically around the projecting portion into the recess so that the bonding face of the other workpiece becomes shaped complementarily to that of the first workpiece such that the workpieces are mechanically interlocked and a diffusion layer is formed. A tubular workpiece 1, e.g. of stainless steel and provided with a female generally frusto-conical surface with steps therein is, arranged above a workpiece 2 of AlMg 3  with a plain male frustoconical surface in support sleeves 7, 8, on a base 6. The workpieces are surrounded by an induction coil 9 and the assembly is positioned in an evacuated chamber 3. The workpieces are heated to 500 C. by the induction coil, the temperature being measured by a thermo-couple inside a core 10, and pressure is applied by a piston rod 4 and pressure plate 5. The material workpiece 2 becomes plastic and flows into the steps of the bonding face of the still solid workpiece 1 and pressure is maintained to form a diffusion layer at the junction. The support sleeves 7, 8 are removed after joining by a chip-removing operation. Stainless steel to aluminium and metal to non-metal junctions can be formed.

Title: Improvements relating to Methods and Apparatus for Scanning a Pattern for the Production of Control Strips.

Abstract: 1,170,947. Photo-electric pattern scanners. FRANZ MORAT G. m. b. H. Nov. 30, 1966 [Dec. 15, 1965; Oct. 19, 1966], No.53653/66. Heading G1A. [Also in Divisions D1 and G3] The colour distribution of an original pattern is converted into markings on a control strip for a machine reproducing the pattern by optically scanning a raster image corresponding to the original pattern a raster point at a time, each raster point corresponding to a colour having a high light transmission or reflection factor within a narrow range of wavelengths of light. As shown, Fig. 10, a photo-electric scanning head 10 is stepped across a screen pattern original drawing 52 to read simultaneously a row of drawing elements representative of a wale of six stitches A-F an X movement being followed by a Y movement. The colours of the six sensed stitches are processed in an electronic system 121 to energize marking pulse generators A1-A24, corresponding to the number of systems distributed over the periphery of a needle cylinder, spaced around a roller 120 by which a film St is moved in synchronism with a circular knitting machine. The marking is produced by exposing a small area of the film surface by a flash of light. The scanning head, Fig. 3, comprises an electronic flash tube projecting light beams, through bores 50a-f in a mask 50, which are focussed by a lens 51 on to an original pattern 52. The light beams are reflected from the six stitch elements and analysed by stacks of photo-transistors 11, 17, 23, 26, each stack comprising six photo-transistors. Stack 11 is responsive to white light and denotes the background to the pattern. Stacks 17, 23, 26 are made responsive to red, green and blue light respectively, by monochromatic interference filters 9, 15, 20. The reflected light is directed through the filters by lenses 7, 13, 18 and mirrors 8, 14, 19. The outputs of the photo-transistors are fed to the control system 121 of Fig. 10, through stacks of preamplifiers 12, 25, 24, 27. In an alternative arrangement, Fig. 2, (not shown), wherein the knitting system is distributed in a wale of eight stitches for a three colour original, the light from the flash tube is projected on to the original pattern through cylindrical lenses and a slit diaphragm; a special track is provided on the control strip for the white background.

Abstract: 1,207,487. Caps for containers. METAL CLOSURES Ltd. 1 Nov., 1967 [30 Nov., 1966], No. 53701/66. Heading B8T. A cap made of a ductile metal has a thin shell 5 which includes a cylindrical portion 10, convex portions 11 and 14 and a security band 15, the members 10 and 15 being re-formed to engage a threaded portion 2 and a rib 4 of a bottle neck respectively when the cap is in position on the neck. An interrupted slit line 16, delimiting the band 15, creates a number of bridges which are put into tension when members 10 and 15 are re-formed. Sections 11 and 14 aid in reducing extra tension on the bridges when the closure and container are handled.

Abstract: 1359240 Cinematography EASTMAN KODAK CO 23 Nov 1972 [24 Nov 1971] 54204/72 Heading G2E In a super-8 type cartridge for a film a snubber 148 is provided as part of the film guiding apparatus between the supply and takeup chambers. The snubber 148 includes a frustum 149 non-rotatably mounted on a resilient stem 153, the frustum having its broader end remote from the stem 153. Comparison of Figs.2, 3 illustrates how when film tension increases the area of surface 151 in contact with the film increases. The snubber 148 thus smooths surges in the film take-up force and permits smoother movement of film from the supply roll.
