A multi-layer printed circuit, Fig. 1, having wiring 5, 6, 7 at different levels interconnected where required by interlayer terminals 8, is built up layer by layer, alternate layers 1, 2, 3, 4 comprising portions of terminals 8 surrounded by insulating material, and the remaining layers 1a, 2a, 3a comprising portions of terminals 8 and wiring surrounded by insulating material. In the preferred embodiment, a thin film of reduced silver is applied to the upper surface of a glass plate; alternatively a plate of stainless steel, which may be chromium-plated, is used. A layer of copper is deposited by electrolysis, and terminal portions are formed therein by a photo-etching process. A filling of epoxy resin is then applied around, and flush with, the terminal portions, and is cured; this forms layer 1. The surface of layer 1 is silvered and coated with copper, and conductor 5 together with further portions of the terminals are photoetched; layer la is then completed by a resin filling. Layer 2 is formed in the same way as layer 1, and so on. Finally the multilayer assembly is stripped from the glass or steel plate. Terminals 8 may be drilled to provide axial holes to accommodate component leads, which are soldered to the terminals at the face of the assembly remote from the component.

Filed: 1920-12-01
Abstract: 171,906. Woodburn, R. F. Dec. 1, 1920. Welding.-A continuous seam is produced by passing the parts between continuously-rotated roller electrodes, the current through which is interrupted at intervals. The work is passed between roller electrodes 1, 2, the latter being carried by a beam 3 so that the pressure on the work can be varied. The machine is driven by a pulley 4 on a shaft carrying a belt pulley 5 which drives a pulley 6 on the shaft 7, which drives, through bevel-gear, a shaft 8 which rotates the roller 2. On the spindle of the roller 2 is a sprocket wheel 11, from which the roller is driven by the chain gear shown. A cam 18, driven by chain gear from the shaft 7, rocks an arm 20 to separate the contacts 23, 24, through which flows the primary current to a transformer, the secondary current from which flows through the elec- 'trodes.

Abstract: 1,200,707. Fusible cut-outs. WESTING- HOUSE ELECTRIC CORP. 17 July, 1968 [24 Aug., 1967], No. 34072/68. Heading H2G. The subject-matter of this Specification is substantially the same as that described in Specification 1,200,702, but the claims are concerned with the provision of weakenings in one or more of the blocks of arc-extinguishing material so that the parts so weakened fracture under heavy arcing conditions thus decreasing the pressure of gsaes evolved and increasing the space in which arcing is taking place. Instead of the weakening recess (129, Fig. 2, not shown), described in Specification 1,200,702, grooves 131 may be provided in the blocks 135, 137 so that the walls weakened by the grooves will break up under intense arcing conditions, the arcing then producing arc-extinguishing gases from the generally tubular C-section member 133 which is made of stronger material such as polyoxymethylene.

Abstract: 308,634. Aktiebolaget Separator, and Flight, W. S. Dec. 22, 1927. Recovering wool fat.-Wool washing water is allowed to stand in a settling tank for a short period to permit the separation of its crystalline particles; it is then treated in one or two centrifuges to obtain the separation of the clayey matter and the wool grease. Where only one machine is used, it is of the type shown in Fig. 2. The liquid is introduced by the central pipe and passes to the chamber 2 between the hood 3 and the discs 4. The clayey matter and solid impurities are discharged through channels 5 and interchangeable nozzles 6. The main part of the water is discharged through outlets 7 from a zone outside the outer periphery of the body of discs, and the wool grease is discharged through outlets 8 from the centre of the bowl. Where two machines are used, the clayey matter isseparated out by the first, and the second is used to separate the water and the wool grease. The machines are of the type shown in Fig. 1, and have only two outlets, the lighter material being discharged through the outlet 7 and the heavier material through the nozzles 6.
