Patent DE-2305963-A1 (DE)
Title: Stripping plate for hot-tinning of copper wire - for thin uniform coatings
Inventor: SCHREINER HORST PROF DR TECHN
IPC: C23C2/08
Filed: 1973-02-07
Abstract: The drawing of hot-tinned copper wire (max. dia. 1mm) through a two-part stripping die after tinning, to give a uniform coating of min. 3 microns. The die consists of a capillary tube and a stripping plate. After acid-pickling, washing and hot-tinning, the wire goes through the tube, which has a cylindrical or conical bore, and which is partly immersed in the tin-bath, and then through the plate. There is a gap, pref. 0.5-3 mm between the tube and the plate which fills with tin and carries away any impurities not already eliminated by the tube. The plate can be made of quartz, alumina, corundum, stainless steel, nickel or heat-resistant platic. This stripping die can be placed above or underneath the bath. Tin coatings 8 microns thick with a tolerance of plus-or-minus 1.5 microns can be obtd. The process is suitable for coating copper or its alloys with tin or tin alloys.

Title: Mould closure protection actuated by obstruction - reverses closure motion if pressure sensitive plate touches obstruction
Inventor: BRODERICK WALTER M
IPC: F16P3/12
Filed: 1973-06-19
Abstract: A protective appts. for a pressure moulding machine or press is used for preventing the two pressure plates from coming together if there is any obstruction between them; by detecting the presence of the obstruction, the sensors act through an electromechanical reverse appts. to open the mould again. The system is as follows: the moving mould plate is fitted in advance of itself with a pressure-sensitive plate which can slide relative to it, but is anchored so that the gap between the two plates cannot exceed a given amt.; the front face of the movable plate has a number of slots or grooves extending from the upper to the lower edge and each housing a flexible spring leaf attached at one end to the movable mould plate and bearing at the other end against the pressure-sensitive plate; the pressure-sensitive plate; is fitted with supporting brackets having rollers running on the guide bars or the mould as a supporting rail guide. There are two sets of microswitches; one set is mounted on the fixed place and the other on the movable plate; if the set mounted on the movable plate is actuated by a pushing back of the pressure-sensitive plate against this microswitch, i.e. if an obstruction occurs between the pressure plates, then the mould closure operation is reversed.
