Patent DE-2008932-A1 (DE)
Title: Mechanical linking of sheet edges
IPC: F16B5/00
Filed: 1970-02-26
Abstract: In connecting edges of sheets or strips when forming cold formed hollow profiles, (1) the unworked edge of one of the two strips is slit with dovetail cuts so that the edge of the strip forms alternatively the shorter and the longer base line of the trapezium-shaped edge elements, and (2) these are alternatively bent upwards and downwards and pushed below and above the edge of the sheet to be joined. Prefd. the joint is passed between pressure rolls which make the sheets interlock.

Title: Hot dip galvanising plant
IPC: C23C2/00
Filed: 1970-03-26
Abstract: Hot dip galvanising plant for tubes consists of a bath and dipping and removal devices. The dipping device includes two stations, one above the other, for accepting workpieces, a transport device which can be raised or lowered by an amount which is equal to the height of the two stations, and also on either side of this, shelves for holding the workpieces. Of these the holding device on one side is loaded when the transport device is raised, whilst that on the other side is loaded when the transport device is lowered. The transport device itself is always loaded on the side opposite to that of the shelves which, are charged. This installation, requires a shorter bath, and secondly enables the duration of the dipping process to be more accurately controlled than in concentional plant.

Title: Refining copper-nickel alloys - by oxidation with subsequent removal of lead, tin and sulphur
IPC: C22C1/02
Filed: 1970-07-22
Abstract: Purification of copper-nickel alloys obtd. from contaminated waste materials and shot is effected by first refining the melt with oxygen to reduce impurities such as Al, Ti, Cr, Zn, Si, Mn and Fe; then heating it under vacuum to remove Pb; introducing chlorine during this stage to expel Sn; and desulphurising by repeated melting in the presence of CaC2 and CaF2. By this method, Cu and Ni can be economically recovered from impure materials.

Title: Surface coating plates by explosive welding - using small supports between coating and base plate which do not adversely affect weld strength
Inventor: APALIKOW JURIJ IGNATJEWITSCH
IPC: B23K20/08
Filed: 1972-11-03
Abstract: The supports should be hollow and may be cylindrical triangular or conical with a wall thickness of an order of magnitude smaller than the thickness fo the plates being joined. Their distance apart depends on the weight of the top sheet plus explosive. For a 5 mm stainless steel sheet which, with explosive, weighed 90 kg, they were made of 0.15 mm thick material, 8 mm high, placed at 1 m intervals. By making the supports of the same material as one of the sheets, they are assimilated into the combined plate without affecting the surface finish. They can, often be placed round the edges so that they are removed by further operations such as drilling for bolt holes.
