Patent DE-2547857-A1 (DE)
Title: Cartridge filter unit construction - using thermoplastic adhesive to seal element to casing and top cover to casing
Inventor: SOYER WOLFGANG
IPC: B01D27/07
Filed: 1975-10-25
Abstract: In a filter casing the element is sealed to the inside of the shell by means of a thermoplastic adhesive, and the cover is similarly sealed to the shell to form a pressure-tight unit, the cover to shell joint having a crimped or corrugated construction for mechanical strength. Process used for mass-produced pressure filters for liqs. having sealed-in elements. Since a single injection of thermoplastic adhesive serves to make both the element-casing seal and the cover-casing seal, the mfg. process is simplified. Compared to the use of two-component liq. based adhesives there is less liq. spillage or contamination of the prodn. line.

Title: Cracked gas generator safety device - replaces fuel and air supply at shutdown by pressurised exhaust gas introduction
Inventor: MASSAR ERNST DR
IPC: F02M27/02
Filed: 1976-06-03
Abstract: The supply of fuel and air to a cracked gas producer in the suction pipe of an internal combustion engine is interrupted just before each cut-out of the ignition. At the same time, exhaust gases from the engine are directed into the reaction space of the catalytic gas producer at a high enough pressure to prevent any influx of fuel or air to it. Engine and cracked gas producer for it can thus be shut down without damage or soot clogging in the catalyst. A container (13) is kept pressurised by exhaust gases by occasional opening of a valve (14) in the branch (12) of the exhaust pipe (10) of the gas turbine (2). To shut down the turbine, the valve (4) in the supply line (5) of an atomized fuel/air mixture to the cracked gas producer (1), filled with a catalyst (3) is closed, and the valve (15) is opened. The exhaust gases are finally trapped in the producer by closing the valve (7) too.

Title: Insulating jacket for pipe - has heat expandible plastic lengths fed onto pipe before passage through die
Inventor: THEMAN JARL
IPC: F16L59/02
Filed: 1977-02-22
