Title: Swelling clay sand prepn - from dry clay
IPC: F27D3/00
Filed: 1971-01-18
Abstract: 0.25 to 4 mm particle size swelling clay sand is produced from ground, dried, homogenised swelling clay, which is passed at a constant layer depth through a shaker passage, where by means of a spray not employing compressed air a liquid of a given viscosity is sprayed onto the clay material.

Title: Hydrostatic/pneumatic positioner - one of two partitions formed by operating piston
Inventor: BUSCH KONRAD DIPL-ING
IPC: F15B11/12
Filed: 1973-07-28
Abstract: The improvement against prior designs lies in the reduction of the necessary partitions from three to two resulting in shorter overall lengths. The partitions are fitted with control openings along their operating path, connecting from one partition via a switching valve to the supply line, from the other partition via a switching valve to the return line. The hollow spaces on either side of the partitions and/or pistons are interconnected so that after opening of two switching valves allocated to the same position, the partitions align on the corresponding control openings. When rotary operation is involved, the design permits a larger operative angle.

Patent DE-2344989-A1 (DE)
Title: Machine for transverse separation of continuous packing film - has an eccentrically driven semicircular triangular or square cutter
Inventor: SCHMIEDER KONRAD
IPC: B26D1/26
Filed: 1973-09-06
Abstract: This machine is used especially for cutting lengths of packing film from continuous strip for use in a packing machine. The strip is cut by a cutter which is rotated and simultaneously moved across the strip. The cutter has variable radius and it is rotated by its shaft by a rack and pinion drive. The actual cutting path length is longer than the servo system travel path because the actuating shaft is eccentrically arranged on the cutter. The cutter starts its rotation when the adjusting element starts its movement. This arrangement saves space and the design is highly compact. The cutter blade can have triangular or square shape. The low mass of the cutter blade ensures high cutting speeds.

Title: Cable with plastics foam insulation - is produced by applying plastics powder preheated wire(s) with subsequent sizing and plastics foaming
Inventor: ZIEMEK GERHARD DR ING
IPC: H01B13/16
Filed: 1974-02-01
Abstract: The insulated wire is produced by drawing a preheated wire through a coating chamber, in which plastics powder is electrostatically deposited onto the wire. The plastics layer is then sized tot he required thickness by passing the coated wire through a die. After sizing the wire is then again heated to polymerise the plastics which is foamed by irradiation and finally cooled before winding onto a storage drum. The plastics can be e.g. polyethylene with a polymerising temperature of 230 deg. C and a foaming temperature of maximum 250 deg. C. The process produces wires with thin insulation cheaply and with a high degree of foam.
