Title: Hydrocarbon emission filter system vehicle fuel tanks - has additional filler contg. active carbon@, porous polymer etc. for reducing desorbed hydrocarbon concn. peak
Inventor: BLUECHER HASSO VON
IPC: B01J20/28
Filed: 1991-06-12
Abstract: In a filter system for preventing hydrocarbon emission from vehcicles with OTTO engines, having an adsorption filter (F1) which, during travel, is desorbed in counter-current by the engine intake air, the novelty is that the hydrocarbon concn. peak, occurring on desorption, is reduced by a succeeding adsorption filter (F2). The adsorbent may be active carbon, a porous polymer (esp. based styrene/divinyl benzene) or a hydrophobic zeolite and may be adhesively bonded pref. to a reticulated coarsely porous polyurethane foam matrix. USE/ADVANTAGE - Used to prevent emissions from carburettors and fuel tanks. The additonal adsorption filter provide smoothing of the desorbed hydrocarbon concn., esp. when large (4-5l) filter canisters are used.
Patent DE-4120807-A1 (DE)
IPC: A21C11/00
Filed: 1991-06-24
Abstract: As a result of a long prefermentation time, the round dough balls increase their volume by at least three fold and are thus opened up so that a low thrust suffices for pressing to form a uniform flat dough plate and, as a result, the fermentation gases are retained in the dough plate. Secondary fermentation can be dispensed with. The pressing process is carried out on a heatable revolving belt, the pressing stamps for carrying out the pressing process being matched to the advance of the belt. The round dough plates can be prebaked on the revolving delivery belt. The pressing stamps are furnished with exchangeable and heatable pressing heads, a counterthrust support being assigned beneath the continuous belt to each pressing stamp. The use of additional baking supports in the form of baking sheets can be dispensed with.
