Abstract: A device for the preparation of a hot beverage comprises a water reservoir, a flow heater and a brewing device. The water reservoir has a connection element for cold water. The water reservoir is fluidly connected to the flow heater, so that the flow heater can be filled with the cold water from the water reservoir.

Abstract: The invention relates to a device for metering an additive into a fluid, containing a valve body, a fluid inlet, and a fluid outlet. A first channel system extends between the fluid inlet and the fluid outlet in the valve body, and a second channel system extends between the fluid inlet and the fluid outlet in the valve body such that in the operating state fluid can flow from the fluid inlet to the fluid outlet either through the first channel system or through the second channel system. The valve body contains a docking element which is configured for docking a cartridge for the additive. A switchover device is provided which can be switched if the cartridge is docked such that the second channel system is fluidically connected to the cartridge when the cartridge is connected to the docking element.

Abstract: A system and method for producing an extract from an extraction material by means of an extraction agent comprises a supply line for the extraction agent, a heating device, a brewing device for the extraction material and an extract collection container. The supply line contains a measuring element and at least one volumetric flow control element for the volumetric flow of the extraction agent. In addition, the temperature of the heated extraction agent can be measured by means of the measuring element. The system comprises a control unit, the control unit containing a dosage regime for the heated extraction agent for the brewing device. The dosage regimen can be selected by means of an input device, whereby the volumetric flow control element can be set according to the dosage regimen and is monitored via the measuring element.

Abstract: An eye surgical unit, comprising a connecting module to align, upon coupling of the connecting module to a connecting module of an eye surgical instrument, an end of a light guide which is included in the connecting module of the eye surgical instrument with respect to the connecting module of the eye surgical unit. During coupling, the connecting modules of the eye surgical unit and the eye surgical instrument mutually cooperate. The mutual cooperation of the connecting modules is realized through a multiple-thread screw connection of which corresponding screw connection elements, upon coupling of the connecting modules through mutual rotation of the connecting modules, mutually engage substantially simultaneously.

Abstract: Wire processing apparatus (10). The apparatus (10) includes an electronic memory for storing values commensurate with the lengths from a terminal end of the wire (21) to the positions of cuts to be made through the plurality of coating layers (X,Y,Z), and a mechanical store for controlling the depths of each cut. Threaded shafts (84, 84, 84) are mounted upon a turret which is movable both rotationally and axially with respect to the wire being processed. The electronic memory is preferably adapted to receive inputs representing parameters of sequential steps in each of two processing operations, and to perform such operations alternately, upon different wire ends, upon successive actuation's of the apparatus (10). A further feature of the apparatus is an arrangement permitting the force exerted on the wire (21) by a pair of gripping members (32, 32) to remain substantially constant over a range of different wire diameters.
