Title: Tubular rib knit edges - are closed by an elastic seam to allow easy garment assembly
Inventor: MUCK SIEGFRIED
IPC: D05B23/00
Filed: 1979-07-20
Abstract: The open end of the tubular knitted material is closed, after the knitting process, by a seam which is elastic and does not match the stitches of the knit. The process ensures that the stitches are held, and will not run, while allowing the fabric to be joined by a conventional chain stitch sewing machine. This means that knitwear garment sections can be assembled cheaply with unskilled labour.

Patent DE-3023598-A1 (DE)
Inventor: KAVCIC ANDREJ
IPC: G08B25/04
Filed: 1980-06-24
Abstract: The alarm system contains a central unit which feeds detectors (9, 9') by means of a line (8). The detectors contain consumers (11, 11') and alarm circuits (9b, 9b'). The central unit is designed in such a way that it feeds the loads, for example, during the negative half-cycles of an AC voltage generator (1) and the alarm circuits during the positive half-cycles. The alarm circuits contain a sensor (13, 13') in series with a constant current source (14, 14') and light-emitting diodes which assume the role of zener diodes. An arrangement of this type on the one hand allows the central unit to detect a short circuit on the line without triggering a false alarm and on the other hand allows active detectors to be used, thus substantially reducing the susceptibility of the system to external interference. <IMAGE>

Title: Double screw extruder has bi:metallic insert - composed of two liners and two bars welded or soldered together
Inventor: THEYSOHN FRIEDRICH
IPC: B29C48/03
Filed: 1980-11-17
Abstract: A double-screw extruder has a bimetallic insert to provide the highly wear-resistant internal lining of the twin barrels; the insert has accurate, constant dimensions over its entire length so that it can be readily fitted into the surrounding casing and has continuous longitudinal beams at the constriction lines of the figure-of-eight cross section. These beams can be tightened into the surrounding casing by means of screws (not shown). The two parts of the bimetallic insert are firmly bonded together at their mutually opposite faces and also in this zone to the two longitudinal beams, so that there is no gap at all in this region. With this arrangement, a bimetallic insert can be easily and inexpensively made to a high degree of accuracy since all the components can be accurately machined and accurately fitted together. To fit the insert into the surrounding casing, it is only necessary to pinch it together slightly at the two beams, then slide it into the casing and tighten up the beams by pulling them apart by means of fixing screws.
