Title: Manufacturing non-cylindrical metallic wires
IPC: B21B1/40
Filed: 1971-01-19
Abstract: Manufacture comprises subjecting a wire to thermal treatment and forming the final cross-sectional shape by cold drawing. Utilizesas raw materials steel wires, the thermal treatment of which depends on the nature of the metal and the intended use for the product. The metallic wire can originally have a circular or rectangular cross-section but any other cross-section can be suitable, depending on the final cross-section desired. Advantages are better orientation of the molecules than by laminating a round wire and greater resistance to fatigue. Furthermore the wire has less internal tension than in other processes. Non-cylindrical metal wires are used particularly, but not exclusively in the manufacture of springs.

Title: Calendar rollers - with controlled feed rate
Inventor: BAUMGARTEN WILFRIED
IPC: B29B7/56
Filed: 1972-03-17
Abstract: A continuously-fed calendar has a source of radioactive emanation attached to one end and a detector to the other end of one horizontal roller. The beam of radiation passes parallel to its roller and is interrupted when the bead of material between the rollers increases in size. This interruption is linked to the feed drive which is then reduced. When the beam is not interrupted the feed drive is increased. By this means the rollers and their bearings are kept under steady load.

Title: Vertical filter plate enclosed in cloth - having batten along top edge to hold cloth edges and form upper boundary for cake
Inventor: RAMSTECK WOLFGANG
IPC: B01D29/39
Filed: 1973-01-17
Abstract: A filter plate, forming part of a multi-plate, Moore-type filter is encased in a filter cloth with suction pipe attached to the top and is immersed vertically in the tank with its top exposed. The upper horizontal edge of the filter plate is covered with a batten of generally flat, inverted U-section fitting over the top of the plate and extending a small way down the sides to enclose and hold the top of the filter cloth, the filter cake thus builds up to the underside of this batten but cannot form across the top of the plate. This arrangement prevents any build-up of cake material on the top of the plate and thus facilitates cleaning.

Title: Shuttering plate for concrete components with cavities - has number of flat boxes connected with each other to form unit
Inventor: HESS HERBERT
IPC: E04G11/46
Filed: 1973-09-21
Abstract: The individual flat boxes are arranged closely adjacent to each other and connected. Their underside is reinforced in such a manner that the shuttering plate produced is capable of carrying loads and hence it is no longer necessary to use flat shuttering boards for support. The under side can be flat or it can have structural profiles so that this shuttering plate can be used additionally for other shuttering. The edges of these shuttering plates can be connected to additional plates. The flat box side is joined to the underside plate. Reinforcement can be arranged within the hollow section. a simplified structure is obtained and less shuttering is used than in prior art constructions.

Title: Semiconductor contg. silicon with uniform basic doping - and much lower effective output doping, giving high resistance
Inventor: PLATZOEDER KARL DIPL PHYS DR
IPC: H01L29/74
Filed: 1973-11-14
Abstract: In a high-resistance semiconductor element with a Si semiconductor having at least 2 zones of opposite conductivity type, inner zone(s) with doping defined by the basic doping of the Si and outer zone(s) forming a pn-junction taking the blocking voltage, the variation (microvariation or striations) of the basic doping of the Si used is not more than plus-or-minus 5%. This basic doping pref. is produced by converting Si to P using thermal neutrons. The effective output doping should be less than the basic doping by at least a factor of 5. Used in avalanche diodes or thyristors with avalanche properties, esp. a thyristor in which the diffusion path of the charge carrier is small compared with the width of the high-resistance inner zone. The barrier effect that can be produced at a given inner zone width and limiting temp. is increased.
