Abstract: A coffee machine has a low overall height and allows an attractive aesthetic design to be achieved in its execution. A brewing block comprising brewing chambers is guided over a circular path, the chambers adopting three different operating positions. Brewing plungers and straining/expelling plungers move axially in the brewing chambers. Drive and control of the brewing assembly is effected by way of spur gears and cam discs which are housed in two cam disc housings located opposite one another. In accordance with a method according to the invention, the rotation to the three positions takes place in steps of 30 degrees, with resetting taking place through 60 degrees.

Abstract: A device for brewing coffee, tea and the like. A rotor with three circumferentially spaced cells is mounted for a stepwise rotary movement within a cylindrical housing to move each of the cells successively to each of three circumferentially spread locations, where an ingredient's inlet, a filter and a discharge opening for dregs respectively are provided. A source of pressurized air is provided at a location within a transitional area between the ingredient's inlet location and the filter location so as to be active as an agitation means in the filling and extracting phase and as a means for expelling the extract in the filter phase.

Abstract: An apparatus for kneading portioned dough pieces comprises a drum (2) rotating around a horizontal axis and being provided on its periphery with alternatively disposed receiving openings (3,4) of different size for the dough to be kneaded. In each receiving opening (3,4) a piston (43) is guided in radial direction and a restricted guidance (48) is provided for the adjustment of these pistons. A change-over means (50) enables one to position always only one of the two sizes of the receiving openings (3,4) below the kneading device (25), so that this kneading device is common of all sizes of the receiving openings (3,4). Thereby, dough pieces having a large range of weight can be kneaded (FIG. 1).

Abstract: A filter vessel has a beverage outlet and a closing device movable between closed and open positions in which a plug blocks and, respectivley, frees the outlet. The closing device has an operating member pivotally secured to the filter holder for movement toward and away from the outlet; and a leg disposed below the outlet and carrying the plug. The leg has a resilient end portion supported on the operating member, while an opposite end of the leg is pivotally secured to the operating member so that the leg may move relative to the operating member towards and away from the outlet. There is further provided an abutment member disposed on the filter holder and being in engagement with the leg at a location between the plug and the pivotal end of the leg.
Abstract: A method and an apparatus for making beverages, such as coffee, soup, tea, or the like, wherein a starting product, such as ground coffee, is supplied to a cavity and is enclosed therein by a piston. After this, through an opening provided in the piston, a quantity of fluid, in this case water, originating from a water system is pressed into said cavity. Hereafter, the fluid, after extraction of the starting product contained in the chamber, in this case filling chamber, is discharged through an opening near the end opposite the piston, the control of this process taking place electronically. The method is characterized in that use is made of an apparatus having at least two filling chambers of different size and mounted on a movable holder and that the various steps are performed during a single cycle of the holder.
