Title: Slide fastener with two helical rows of teeth made of plastic monofilament
Inventor: PROBST ANTON
IPC: A44B19/40
Filed: 1989-02-25
Abstract: Slide fastener with two helical rows of teeth made of plastic monofilament, the teeth basted together by connection parts in each case having a coupling eyelet which consists of a lower leg on the carrying tape side, an upper leg and a coupling head, and with two knitted carrying tapes. The rows of teeth lie on the carrying tapes with the coupling heads protruding over the inside carrying tape edges. Stitch wales lying in the carrying tapes are connected to one another by means of weft threads. The teeth are connected to the carrying tapes with the aid of tie-in stitch wales engaging jointly over the upper legs of the teeth and the underlying areas of the lower legs, these tie-in stitch wales being knitted into the carrying tapes. The lower legs of the teeth are engaged by at least one additional, separate lower leg stitch wale to form a filling thread, the lower leg stitch wale being knitted into the associated carrying tape alongside or between the tie-in stitch wales. In each stitch course the stitches of every second stitch wale (regardless of whether it is a tie-in stitch wale or a lower leg stitch wale) are offset by a part stitch in relation to the stitches of every first stitch wale. <IMAGE>

Patent DE-3937348-A1 (DE)
Inventor: HAGENBUCH ERNST
IPC: A41G1/04
Filed: 1989-11-09
Abstract: The invention relates to a method for producing a semifinished product for the fabrication of a blossom-like rosette. Such blossom-like rosettes cannot be fabricated using known strip-type semifinished products which have a pulling member. Only loops are formed which have to be worked by hand in a complicated manner if required. A method is therefore to be proposed which employs simple means for fabricating a suitable semifinished product, with which blossom-like rosettes can be produced very simply. This is achieved in that a strip (1-13) of any desired suitably flexible material is produced in any desired manner which is provided at least in the direction of its longitudinal extension with at least one straight flexible pulling member (14-28) which is not covered by the flexible strip (1-13) in some portions of its longitudinal extension, at least one longitudinal edge of the finished strip being produced with a non-straight contour (31), and, furthermore, the free portions (30) on the pulling member (1-29) being dimensioned in terms of their length such that a desired folding size results.

Patent DE-4016203-A1 (DE)
Inventor: TRAUTNER ROLF PROF DR
IPC: H04L9/06
Filed: 1990-05-19
Abstract: The process is for the blockwise coding of digital or digitised analog data. At a moment j, the plain text is read into a first operation register as a binary data block (T)<(j)> of L bits and then converted there into an intermediate text C1<(j)> by means of a temporary code S1<(j)> and a reversible function F. The intermediate text C1<(j)> is then transferred in parallel to a second operation register in which it is converted into an intermediate text C2<(j)> by means of a temporary code S2<(j)> and the reversible function F. After a total of R such conversion steps there exists the intermediate text CR<(j)> representing the code text C<(j)> at moment j, whereby the transfer of the individual intermediate texts from one operation register to the next takes place simultaneously in parallel in accordance with the systolic algorithm. The conversion of the data block in operation register k takes place in several steps, whereby the number of steps is set and the individual steps are formed by rapid elementary operations. The sequence of the elementary operations is determined by a variable permutation Pik<(j)> which forms part of the code Sk<(j)> and is so formed that each of the conversion steps is completed precisely once.
