Abstract: Circuit arrangement for heating elements of cooking surfaces of ranges having at least two individual cooking regions with a respective control device for generating variable heat capacities, the individual cooking regions being connectible together for joint use, including heating elements operatively associated with the individual cooking regions and disposed in current paths switchable by switching elements in a manner that, in a first switching mode, the heating elements of the individual cooking regions are selectively connected to a respective heat-capacity control device and in a second switching mode, are jointly connected to one of the heat-capacity control devices, the other of the heat-capacity control devices being separated from the respective heating element associated therewith.

Abstract: Continuously operating adsorption refrigeration plant, comprising a gas-tight housing having at least one expeller chamber and at least one adsorption chamber disposed therein sequentially following each other in a close loop, sealing gates disposed between the chambers for preventing an uninhibited exchange of gaseous coolant between the chambers, an endless structure disposed in the housing including carriers for solid adsorbent of a coolant and connection members spacing the carriers apart from each other, the carriers being movable one after the other through the chambers of the housing.

Abstract: Coffee machine with a centrifugal filter releasably coupled suring operation with a motor shaft and receiving brewing water via a transporter disposed thereon and rotatable therewith including a plurality of transport channels for brewing water distributed around the periphery of the transporter.

Abstract: Electric coffee machine with a centrifugal filter which, via a rotating transporter disposed thereon collects boiling water from a heated water bowl disposed therebelow, and with a casing surrounding the water bowl, comprising means for rotatably mounting the centrifugal filter on the water bowl, and elastic buffer elements moveably supporting the water bowl on the casing.
