Patent DE-3580984-D1 (DE)
Inventor: AUSTIN KENNETH
IPC: H04B1/46
Filed: 1985-07-17
Granted: 1991-01-31
Abstract: A communications scrambler operates on a digital basis in which digital or digitised incoming and outgoing signals are merged (60) into a single bit stream for application to a binary bit store (12) and retrieval therefrom for separation (62) of those signals. Multi-bit segments of each signal represent unintelligibly fragments of those signals and are stored and read-out under control of store addressing counters (36, 38, 76) whose outputs are selectively modified (48, 50) to achieve time-dispersion encryption/decryption for outgoing/incoming signals in multi-plexed writing and reading of the store (12). Digitisation (52, 54) and reconstitution (64, 66) of analogue incoming and outgoing signals is provided using inherently digital on-chip circuitry and one-bit per sample at a high rate for easy interfacing in telephone/radio systems. The whole control system can be put onto a simple semi-conductor chip of ULA type.

Title: Vertical machine for making bags from a tubular web
Inventor: KLINKEL WOLFGANG
IPC: B65B9/20
Filed: 1986-02-04
Granted: 1988-08-18
Abstract: To fill low-weight, high-volume goods, such as potato chips, popcorn and the like into bags as the bags are being made, the fill goods are introduced into a hopper and a filling funnel which is joined to a fill tube. The fill tube has air inlet openings at the upper portion, air outlet openings at the lower portion, and then continues to a holder and bag-forming tube. A film (102), for example, of plastic, is wrapped about the bag forming tube (105), and seamed vertically, so that the tube is being made as goods are introduced into the hopper and funnel. An air stream (B) is generated longitudinally in the fill tube (103) by introducing air under above-atmospheric pressure into the upper air inlet openings (104) formed as downwardly directed flap nozzles (119), the air being removed from lower openings (122) and, for example, recirculated in the recirculating blower (107), the openings being closed off outwardly by a jacket forming respective air inlet and outlet chambers (111,116). The fill goods are accelerated downwardly, while being prevented from "dancing" above the introduced air by the volume of the fill goods themselves within the hopper or inlet funnel (101). The bag is formed by usual vertical bag seaming apparatus (131) and cross-seamed, pinched and severed by filling and pinching jaws (113).

Abstract: An electrostatic precipitator is fed high voltage pulses by a pulse generating circuit including a high voltage transformer and a first thyristor switch connected in series with a primary winding of the transformer. Magnetic saturation of the core of the high voltage transformer is prevented by recurrently short circuiting the primary winding of the transformer by means of a second thyristor switch connected in parallel to the primary winding. The second thyristor switch is closed for a period of time extending from a first instant following a high voltage pulse crest to a second instant at or before the start of a pulse generating cycle subsequent to the pulse crest.
