Patent DE-2657355-A1 (DE)
Inventor: ANDERL SIEGFRIED
IPC: A47J31/00
Filed: 1976-12-17
Abstract: The brewing device has a brewing chamber (1) in which a filling valve opening (5) and a blowoff valve opening (12) leading to an outlet (13) are axially flush with one another. Arranged in the lower region of the brewing chamber is a filtering sieve (14) and, below that, a collection space (15) for brewed coffee. From the collection space the coffee pipe (16) goes to a collection vessel. The brewing operation is controlled by means of a valve piston (18) which is displaceable axially relative to the valve openings and closes the latter in a sealing manner depending on its position. By means of cleaning liquid supplied, the used ground coffee is rinsed through the blowoff valve opening into the outlet. In this case, complete emptying and cleaning of the collection space below the sieve and of the entire valve tappet (19) is difficult. Thorough cleaning is allowed by at least one emptying channel (17) leading from the collection space to the outlet and by at least one section (22) of reduced diameter on the valve body which, in a rest position which differs from the brewing and the cleaning positions when the blowoff valve opening is closed, leaves the connection between the emptying channel and the outlet open. At the same time, the filling valve opening is open. In this position, a new brewing operation can begin immediately after filling with ground coffee, dry or with soaking water, while the valve piston moves in the direction towards the brewing position. <IMAGE>

Title: Reducing gas generator - in which gas produced by combustion of hydrocarbon fuel is mixed with industrial tail gas
Inventor: BEAVON DAVID KENT
IPC: F23G7/06
Filed: 1977-09-01
Abstract: Appts. in which a hot reducing gas free of molecular O2 and soot is generated by combustion of hydrocarbon fuel and then mixed with industrial tail gas comprises a combustion chamber lined with a refractory material. Jets of fuel gas and steam are directed through a throat at one end of the chamber axially aligned with an outlet at the other. O2-contg. gas is introduced tangentially into the combustion chamber through a windbox at a high rotary velocity. Industrial tail gases are introduced into a cylindrical jacket which surrounds the combustion chamber and extends beyonds the outlet end of the chamber to provide a zone in which combustion prods. exiting from the combustion chamber mix with the industrial tail gases. Prior to mixing with the combustion prods. the industrial tail gases serve to cool the combustion chamber and are themselves preheated. The addition of steam to the hydrocarbon fuel gas prevents soot formation by reducing any thermal reaction in which free C is released from the hydrocarbon molecules.
