Patent DE-3840750-A1 (DE)
Inventor: STRASZEWSKI KLAUS DIPL ING
IPC: F16L11/12
Filed: 1988-12-03
Abstract: A plastic part, in particular a fuel line, consists of an inner layer of plastic crosslinked by irradiation and surrounded by a layer of plastic containing a foaming propellant. The reaction temperature of the foaming propellant is higher than the processing temperature of the plastic layer containing the propellant. The action of heat causes foaming of the plastic layer containing the propellant. The service life of the plastic part exposed to heat is thereby essentially improved.

Title: Band-knife machine with conveyor for handling material after cutting - in which conveyor is divided into sections which can move at different speeds to improve handling of variable materials
Inventor: TRUETSCHEL WILLI
IPC: C14B17/06
Filed: 1989-07-11
Abstract: The band-saw or band-knife is provided with a conveyor which guides the separated material away from the knife after cutting. It is proposed the conveyor be divided perpendicular to the direction of material motion into at least two parts which are driven at different velocities. Three conveyor sections may be used, and the two outer ones driven faster than the centre one. The conveyor belts (12a, 12b, 12c) are arranged above each other, the centre belt (12b) being driven by a chain drive (34) while the outer two belts (12a, 12c) are driven at a higher velocity by a second chain drive (35).  Three pressure rollers press the item being cut against. these conveyor belts. USE/ADVANTAGE - This invention is used in the design of band-saws or knives, and allows material of continuously varying properties to be more efficiently handled. For example, in cutting an animal skin the strong centre part of the skin will move through the knife more quickly than the softer outer parts, and this tends to produce wrinkles which jam the knife and spoil the product. Conveyor sections moving at different velocities will reduce or eliminate this problem.

Title: Single-double sideband filtering and demodulating - converting signal with or without carrier into LF range from IF plane
Inventor: ARNOLDT MICHAEL DIPL ING
IPC: H03D1/24
Filed: 1989-11-09
Abstract: The filtering uses an integrated circuit with a combination of an LF low pass filter and a narrow band LF band pass filter, forming a switch-capacitor filter (SKF). The resonance frequency of the band pass filter is slightly above the limit frequency of the low pass filter. The single or two-side band signal is converted into LF range from the IF plane of radio receiver by the SKF scanning. The desired signal side band lies in the pass range of the low pass filter. The carrier lies the pass range of the band pass filter. Both signals are then fed to sync demodulator mixer (M) for desired LF signal generation. ADVANTAGE - Low-cost suppression of disturbed side band.

Patent DE-4016183-A1 (DE)
Inventor: VOCKE PETER DR
IPC: C21D1/76
Filed: 1990-05-19
Abstract: The invention relates to a process and apparatus for preparation of treatment gas used in heat treatments, whereby the treatment gas is produced in a furnace disposed catalyst retort at a temperature of that of the furnace in which the retort is positioned. With such processes, when using lower furnace temperature ranges, problems occur with respect to the reaction of the feed gas in the catalyst retort. To provide an improvement, the catalyst retort in the furnace is surrounded by a shield, and the treatment gas generated in and leaving the catalyst retort is first fed into a space defined by this shield and thereafter released into furnace space. By this, an isolation of the catalyst retort from the interior of the furnace is provided, and relatively higher retort temperatures are available.
