Patent DE-3928717-A1 (DE)
Title: Fast drying processing of grasses and other plants
Inventor: SCHUSTER SIEGFRIED
IPC: A01D43/10
Filed: 1989-08-30
Abstract: The processing system for grass and other plants consists in separating the plant bodies from their root balls and combining then in a flat surface area whence they are supplied to an area for breaking down the plant bodies in their longitudinal direction.  The broken down plant bodies are then laid down on the field for drying either loose or in a mat. The plant bodies which are gathered up flat can be beaten and/or drawn and/or pressed and/or torn.  They can be pressed into a mat before being laid on the field and during this compaction the plant sap can be removed.

Title: Slubbing break repair - has join before drawing which is broken after drawing for splicing together for trouble-free ring spinning
Inventor: MEYER URS DR
IPC: D01H9/16
Filed: 1990-05-08
Abstract: To connect the end of a new slubbing, when a slubbing bobbin is exhausted or the slubbing has broken, the leading end of the new slubbing is joined to the trailing end of the old slubbing before drawing, so that, at the end of the drawing unit, the join is forcibly broken. The broken ends are then prepd. for splicing to give a trouble-free joint in the drawn material. After the joint has been broken, the material emerging from the drawing unit is removed before splicing with the trailing end from the bobbin, and the trailing end from the bobbin is similarly cut free before splicing. The spinning station action is restored after a break by an automatic splicer. The leading and trailing slubbing ends are joined together by a mechanical path deflection unit which forms each end into loops which are formed within each other, to be spliced such as by compressed air. ADVANTAGE - The technique, partic. for a ring spinner, ensures that the spun yarn is of consistent quality without signs of slubbing joints.

Title: Two-stage sulphur di:oxide gas washing process - in which sulphur gases are re-heated before second washing stage using indirect heat recovered from condensing satd. steam
Inventor: KROEDEL BERND DR
IPC: B01D53/50
Filed: 1990-10-31
Abstract: Sulphur dioxide gases produced by the combustion of fossil fuels for steam generation are removed by two-stage gas washers and limestone additives whose consumption increases exponentially with the absorption rate.

Title: Hinged join prodn. between to sections - by co-extruding two opposite semicircular sections and one hinge strip running S-fashion between opposite ends of those sections
Inventor: ROERICHT HANS PROF
IPC: E05D1/00
Filed: 1991-05-02
Abstract: A hinged joint between two sheets or panels is produced where the prod. has at least two hinges, each of which is semi-circular or arc-shaped in cross-section; these meet along a line contact and are joined together to form an S-section running from the end of one semi-circle to the diametrically opposite end of the other semi-circle. Both semi-circular shapes and the hinge strip itself are produced as one piece in a single operation. The semi-circular materials are pref. unplasticised PVC and are coextruded with a plasticised PVC hinge strip in the one extrusion process. More specifically the finished assembly has two semi-cylindrical bodies with bent-in ends to fit on to e.g. a door and wall respectively. They are joined together by hinge strips, each of which forms an S-shape, running from one end of one body to the opposite end of the other body. The two strips run in opposite directions to prevent each other from opening up when the bodies turn. In production the two types of PVC for the bodies and hinges are coextruded. Two barrels express their polymers together out through one common die from their separate flow bores i.e. the hard and soft PVC streams unite shortly before reaching the die. To produce the mirror-image hinges their sections are turned through 180 deg.. ADVANTAGE - The process is simple. The prod. is made in one operation by the use of one main and one subsidiary extruder for the semi-circular sections and hinge strip respectively. The method is thus economical and can produce any desired length.
