Title: Carrier regeneration system for suppressed carrier AM signal - using two multipliers in loop and receiving demodulated and carrier signals respectively
Inventor: HOFFMEISTER KLAUS
IPC: H03D1/22
Filed: 1977-12-23
Abstract: The carrier wave regenerator retrieves the carrier from suppressed-carrier AM signals sent via cable or free space. The received signal is multiplied by the demodulated wanted signal. In a second step the received signal is multiplied by the regenerated carrier wave. The carrier wave is obtained from the result of the first multiplication whilst the demodulated wanted signal is obtained from the second multiplication. A pilot carrier wave may be sent out during relatively long breaks in the transmission of the wanted signal.

Title: Support sleeve for corrugated sausage skin - made of heat shrinkable polyethylene foil with radial holes and reinforced flange ends
Inventor: MICHEL WOLFGANG
IPC: A22C13/00
Filed: 1978-03-06
Abstract: A support sleeve, made of a flexible thermoplastic foil, for corrugated hoses, e.g. for use as sausage skin, ready for application to the filling tube of a sausage machine, is capable of extension and shrinkage. It has a number of radial holes for access to a watering fluid and has reinforced flange ends.

Title: Trapezium corrugation metal sheet prodn. - uses successive converging roller sets to initially produce wave pattern
IPC: B21D13/04
Filed: 1979-10-11
Abstract: The arrangement is intended for producing a corrugated metal sheet with a particular corrugation contour (1) starting from a flat sheet (2) by gradually shaping it as it passes through sets of rollers (5). The sheet is initially and gradually shaped between successive roller sets so that its width is reduced whilst pre-forming the approximate corrugation pattern (4). When the ultimate sheet width is obtained, this pattern is then further shaped (region Pf2) to produce the final, e.g. trapezium, contour (1). In the pre-forming zone (Pf1) the shaping rollers (5) are preferably arranged at angles to the sheet movement (Pf3) to produce corrugation lines (L) which converge towards the final forming zone (Pf2).
