Abstract: The faucet has a fitting body, which has a base (2) that is securable to a wash-stand or a building wall and a housing (3) that is detachably mounted on said base. The housing (3) has a housing (3) that has an outlet member (4) and a water outlet opening (5). An electrically operated valve (6) and a presence detector (7) are mounted on the base (2). The presence detector (7) is mounted in a receiving space (18) of the housing (3) on a holder (8) that has electric contacts (30, 31). The holder (8) is positioned so as to be mechanically and electrically detachable on a contact carrier (58) that is secured to the base (2) and has electric contacts (34, 35).

Abstract: The device has a housing (5) which comprises an opening (4) in which a button (15) is fixed on a receiving part (8) mounted movably in the housing (5). A fitting aid (36) is provided, with which the button (15) may be introduced into the opening (4) in the housing (5) and positioned in a recessed manner therein as well as being fixed to the receiving part (8). Sets of teeth (23, 27) on the receiving part (8) and on the button (15) enable simple and depth-adjustable fixing of the button (15) to the receiving part (8).

Abstract: The device has a housing (5) which can be fastened on the sanitary article (2) and in which is mounted a pushbutton (7) for actuating the drainage valve (A). A pulling element (16) connects the pushbutton (7) to a closure body (33) which is mounted in a displaceable manner in a housing (22) of the drainage valve (A). A changeover device (26) is mounted on the housing (22) of the drainage valve (A) and can be changed over under tension in each case for opening and closing the drainage valve (A). By virtue of the changeover device (26) being arranged on the housing (22) of the drainage valve (A), the actuating part which contains the pushbutton (7) can be designed in a more space-saving and compact manner.

Abstract: A workstation has a feed device (1) for sample tube racks (7), comprising a balance (17) in which the weight of individual sample tubes (6) is determined by a procedure in which the sample tube holder (7) is weighed in each case before and after removal of each sample tube (6) and the difference between the weights is determined. Removal is effected in each case by means of a gripper (23) of a transfer device (3) which then distributes the sample tubes (6) over sample tube buckets (22) in such a way that said buckets form pairs having approximately the same weights. With the aid of a receiving device (27) which is gripped by the gripper (23) and removed from a holder, the sample tube buckets (22) are picked up and introduced into a centrifuge (2). They are removed again after centrifuging and, after the receiving device (27) has been deposited in the holder, the individual sample tubes (6) are removed from the sample tube buckets (22) by the gripper and deposited on carriers (5) of a conveying device (4).
