Title: Knitted tube to be partly cut open
Inventor: KOTZERKE WILFRIED
IPC: D04B35/00
Filed: 1969-04-21
Abstract: Particularly for parts of stretch tights; made on single cylinder circular machine having a cutting needle. Cutting edge of cutting needle is under the tonque, and this needle can be lifted out over the cleaning position by an escape part. The floats to be cut are knitted tighter than the stitch-forming thread parts of the other needles. Preferably the thread parts to be cut are drawn out without sinking, or sinking is shorter than other stitch-forming thread parts. Cutting needle has a foot shorter than other needles', and its sinker part is radially displaceable, i.e. the foot is not gripped when the escape part is in the working position. Advantage: ensures that thread is stretched during cutting.

Patent DE-2015029-A1 (DE)
Title: Expanding tubes hydraulically in a split die
IPC: B21D26/02
Filed: 1970-03-28
Abstract: The lower half of the die is fixed and the upper half pivots about one end to allow the tube to be placed inside. At the other end, the outside of the die is tapered and a similary shaped sealing ring is pushed over this end to seal the two halves together. This ring is flexibly suspended from a rail-mounted bogey so that it can centre itself easily round the mould. It is pushed on and off by a hydraulic ram, down the centre of which passes a rod that carries a bush that seals one end of the tube. When the tube is expanded, some hydraulic fluid escapes down a passage way in the bush to press on its outside surface and seal it against the face of the tube, ensuring pressure tightness.

The steel armouring may be integrated into the form of a cage by welding, screwing etc.
Patent DE-2155855-A1 (DE)
Title: Multi screw press - with partly frusto-conical perforated plates
Inventor: GOEKE WERNER
IPC: B29C48/76
Filed: 1971-11-10
Abstract: A multi-screw press has a rotating perforated plate on each screw shaft, extending to the wall of the barrel. These plats divide the atmospheric zone, upstream of the plates, from the degassing zone, downstream from them. The form of each plate comprises a cylindrical portion of short length followed by a conical frustum (widening for one plate, narrowing for the next plate) having the same cone angle for all plates. The wider end of each conical portion reaches to the barrel wall, except for a small gap. This reduces the compacting action of material entering the degassing zone and eliminates dead corners.

Patent DE-2210927-A1 (DE)
Title: Conveyor rollers - with individual slipping couplings
Inventor: PIECHA PAUL
IPC: B65G13/00
Filed: 1972-03-07
Abstract: Each roller revolves freely round its shaft and has two internal permanent magnets attached to one of its supporting end plates. These magnets form a slipping clutch to an adjacent disc fixed to the shaft, which is driven by a motor. On a system of such rollers, chain driven by a single motor, one can therefore stop without affecting the others, so that the arrangement operates with varying weights of articles conveyed. It is particularly suitable for conveying articles through a sterilising chamber.

Title: Plastics prodn - by reaction in vessel with variable oblique jets
Inventor: KNELL LUDWIG
IPC: B01J19/24
Filed: 1972-05-10
Abstract: A method and apparatus for prodn. of plastics using a conventional, externally heated reaction vessel and lines and control system connecting this to a condenser with viewing glass; the lower part of the reaction vessel is a smooth cylinder contg. no mechanical stirring mechanism; mixing is effected by the introduction of the materials through nozzles, the material leaving from the bottom of the vessel and being recycled through the condenser, heater and cooler. The nozzles can be varied in cross section and direction to give an infinitely variable pressure range and an oblique, spiral downward flow inside the reaction vessel. This arrangement provides better control with less risk of stoppages caused by failure to maintain the correct pH value or temp.
