Abstract: 1393978 Thread supply; yarn storage feeders GUSTAV MEMMINGER [trading as GUSTAV MEMMINGER VERFAHRENSTECHNIK FUR DIE MASCHENINDUSTRIE 20 Dec 1972 [23 Dec 1971] 58702/72 Headings D1C D1E and D1J In a yarn storage feeder the yarn is taken through an axial bore, wound on a stationary cage by a winding eye 20, moved along the bars of the cage by a set of wobbling rods 16, then pulled off through a free-running thread guide 24 which rides round a T-section track 22, and finally passes through a fixed eye 28. Fluid may be applied to the yarn by feeding it from a supply 32 through a pipe 31 into a groove 30 in the inside of the track 22. A sensing device may stop and start the winding-on drive to maintain the yarn store within specified limits. The advancing rods 16 are held by non-rotating elastic discs 15, 17 which are mounted on eccentrics 13, 12 so that when the shaft 7 rotates each rod in turn protrudes between adjacent fixed bars 3 of the cage in a wobbling or tumbling movement.

Title: Holographic evaluation of dispersed systems
IPC: G03H1/00
Filed: 1978-12-11
Abstract: In the determination of the physical characteristics of dispersed systems by holography, which enable the examination of three-phase dispersions and industrial scale tests a laser beam is split so as to perform the illumination simultaneously "in-line" and with a "deflected reference beam" whereby to take a hologram on part of which both beams impinge and on the other part only the "in line" beam impinges. On reconstitution the image of the original system is focussed on a screen, then on the monitor of a closed-circuit television system the image is freed from the background noise of the laser beam by reducing the intensity of the electron beam of a cathode ray device, photographs are taken of the image, and the photographs are evaluated by means of an opto-electronic analyser. By using a pulsed laser and a coupled. shutter for exposing the photo- sensitive plate used to form the hologram, ambient illumination has no adverse effects.

Title: Arrangement for restituting selection signals
IPC: H04L25/64
Filed: 1979-01-05
Abstract: An arrangement for restoring dial pulses which are received as binary signal elements in a binary signal. The mark/space ratio of the dial pulses and the allowable tolerance of this ratio is catered for by allowing a pulse "mark" to be comprised by 2, 3 or 4 binary signal elements A which are binary bits of one value, and allowing a pulse "space" to be comprised by 1, 2 or 3 binary signal elements Z which are binary bits of opposite value. The pulse "spaces" are reconstituted as a fixed duration (or 41 ms in the embodiment described), whereas the pulse "marks" are reconstituted with a variable duration (between 50-70 ms in the embodiment described). The arrangement functions using logic sequences which detect the signal transitions Z-A and A-Z in conjunction with signal element combinations ZZA or AZA which occur in sequentially received and stored signal elements. In Figure 1 a counter 23 counts out the reconstituted mark/space durations under the control of auxiliary counters 18, 33 and 34 which are controlled by A-Z and Z-A transition detectors 15 and 16 which receive signal element information from a store 4 in which successively received signal elements are stored. <IMAGE>
