Patent DE-2710221-A1 (DE)
Title: Self-twist yarn mfr. - has a second stage where yarn is opened up for each component to be twisted in the same direction before twisting together
Inventor: COLL-TORTOSE LIBERTO
IPC: D02G3/28
Filed: 1977-03-09
Abstract: In the mfr. of a self-twist yarn, two rovings are sepd. twisted alternately left and right, and then allowed to twist together spontaneously to be wound. The yarn is unwound as a second stage and given a further twisting along the same direction. In the second stage, the yarn is again sepd. into yarn components and then directly twisted together in a constant directional twist. The process gives a self-twist yarn which is economically developed, giving a consistent twist with high tensile strength.

Patent DE-2813997-A1 (DE)
Title: Transversal filter for programmable network - has charge-transfer shift register reading out serially to form filtered output
Inventor: KANUER KARL DIPL ING
IPC: H03H15/02
Filed: 1978-03-31
Abstract: The filter employs a charge-transfer device as shift register (4) with parallel inputs (2). The weighting coefficients are generated by reading in signal-dependent quantities of charge using weighting circuits (81-83). The charge levels attained by summing in the register are read out serially to construct the filtered output signal. To allow the weighting coefficients to be set electronically over a relatively wide range the weighting circuits are provided with source zones (D1-D3). These are controlled/selected separately or with additional source zones located in pairs on opposite sides of the CTD transfer channel or with transfer gates between the weighting circuits and the register. (The transfer gates have gate-oxide and field-oxide zones). The weighting coefficients can be varied over a range of 1:1000 without requiring the filter to occupy a large area. This wide variation increases the applications for the filter, which is primarily for use in an electronically programmable filter network.

Title: Food smoking system - in closed circuit with blower and side stream through smouldering sawdust bed
Inventor: UNGER KURT
IPC: A23B4/03
Filed: 1978-10-11
Abstract: A food smoking system includes a smoking chamber which receives the smoke from a smouldering sawdust bed in a closed circuit by a blower during the smoking period.

Title: Stacking machine for metal ingots - where tilting frame fitted with clamps transfers row of ingots onto hoist table
Inventor: SCHIFFMANN HANS-WILLI
IPC: B22D5/00
Filed: 1978-12-16
Abstract: The ingots are knocked out of their moulds so they fall onto the lower end of a conveyor belt which slopes upwards.
