Patent EP-0394720-B1 (EP)
Title: Pump for displacement of gases and for generation of differential pressure
IPC: F04C21/00
Filed: 1990-04-05
Granted: 1993-05-12
Abstract: In the pump described here the expansion chamber is hermetically sealed off from the drive unit. In the expansion chamber itself there are no oil-lubricated or grease-lubricated parts, so that the pump may be described as entirely dry. The sealing is achieved by means of a torsional hollow body 5, which is located between a shaft 1 and a pot 6. The shaft 1 performs an oscillating rotary movement which is transmitted to the pot 6. On the latter are segmental pistons 8a and 8b, which oscillate between fixed parts 10a and 10b and so create the pumping effect.

Abstract: The coffee machine is enclosed by a housing (1). Accommodated therein is a fresh water container (2), a ground coffee container (3), a residual water container (4), a grinding unit (5) and control and heating members, denoted jointly by reference numeral (6), for heating and feeding fresh water from the fresh water container to a brewing device (8). The latter is attached to a further housing (19) via spring bars (41) which engage in notches (42). Said further housing comprises a drive motor (15) and a gear mechanism (18) from which a drive axle (20), penetrating the wall of the further housing (19) and producing an operative connection with the brewing device (8), protrudes into a drive spindle of the latter. The brewing device (8) constitutes a first partial module, the further housing (19) with the drive motor (15), the gear mechanism (18) and the drive axle (20) constitutes a second partial module (17) of a first module (16) which can be removed from the machine. In the removed state shown, the operability of the brewing device (8), which comprises all the parts subjected to soiling by coffee powder or coffee, can be checked by the electrical energy for driving the motor, which is still operatively connected to the brewing device (8), being able to be supplied via a socket (21). To clean the brewing device (8), the latter can be lifted off from the second partial module (17) after the removably arranged liquid pipes (29, 30) have been separated. By virtue of the modular construction, cleaning, maintenance, repair and testing work can be carried out easily. <IMAGE>

Date Mar. 18, 1993The invention concerns a method and a device in the cooling of the circulating material in a fluidized-bed boiler. In the method the fuel (A) is introduced into the circulating-powder combustion chamber (10) of the fluidized-bed boiler into the lower part of the circulating-powder combustion chamber (10) and an inert circulating material, which contains a proportion of unburned powdered fuel (A), is circulated from the top part of the circulating-powder combustion chamber (10) to the lower part of the circulating-powder combustion chamber (10). The flue gases are passed in the method from the powder separator (13) along the duct (15) into the exhaust-gas boiler (16), through whose heat exchanger (16a) thermal energy of the flue gases is transferred further to other useful use. In the method, part of the cooled flue gases are recirculated along the duct (20) into the circulating material and, by means of the cooled flue gases, the capacity of cooling of the fluidized-bed furnace is regulated by affecting the temperature of the circulating material.
