Abstract: The invention relates to a biopsy device for the in vivo enrichment of tissue, cells, or analytes, including drugs and therapeutic active substances, at the site of biopsy and for subsequent testing.

Abstract: According to the inventive method, a pawl which in a normal mode of operation is rotatably mounted about a point of rotation when it is in a closed position can be rotated by means of a first actuator, which is controlled by a main power supply and by means of a toothed gearwheel segment which is also rotatably mounted about said point of rotation and which can run freely in relation to the pawl, until an open position is obtained. In the event of an emergency, the pawl can be rotated by means of a second self-inhibiting actuator, which is controlled by the emergency power supply, by means of another rotatably mounted toothed gearwheel segment which comprises a toothed gearwheel having a smaller diameter and which engages with the toothed wheel segment, until an open position is obtained. The emergency power supply is then interrupted and the pawl is maintained in an open position.

Abstract: Described is a process for producing a self-supporting metal foil (40), in particular copper foil, which by virtue of its constitution has a low shearing strength and which can be structured in a sharp-edged configuration. In this case a base layer of the metal foil (40) is galvanically deposited on a roller cathode (22). A cauliflower structure (60) comprising the metal is deposited in firmly adhering relationship on the metal base layer (58) by means of an additional anode (32) provided between the roller cathode (22) and the anode cage (24). The metal foil (40) comprising the metal base layer (58) and the cauliflower structure (60) is detached from the roller cathode (22), rinsed and dried. The dried foil (40) comprising the metal base layer (58) provided with the cauliflower structure (60) is moved through a black oxide bath (46). There then follows a rinsing operation and a drying operation.

Abstract: A vehicle having a central locking system for doors, tailgates or the like, as well as a device for illuminating an interior space of the vehicle, wherein the central locking system has a central control unit (1), and the central control unit (1) has an output (7) both for at least one actuating drive (2) and for the device for illuminating the interior space.

Abstract: The invention relates to a locking device, in particular for a door, a tailgate, a trunk lid or the like of a vehicle, with at least one actuating drive which is capable of being activated in order to set functions of the locking device and which is operatively connected to an element of the locking device via at least one transmission element, according to the invention means being provided which detect the continuous movements and functional positions of the actuating drive or of the transmission element.

Abstract: The invention relates to a closing device for a movable element, in particular for a door, a flap or the like, of a vehicle, having a rotary latch which arrests or releases a closing bolt, it being possible for the rotary latch to be arrested by a detent pawl to effect a closed position of the element and it being possible for the detent pawl to be driven by an actuating drive for the purpose of releasing the rotary latch to effect an opening position of the element, the invention making provision for means which control the actuating drive in such a manner that after the actuating drive has been driven from a rest position in the direction of a working position for the purpose of releasing the rotary latch it is returned in a controlled manner from the working position into the rest position.

Abstract: A process and an equipment for obtaining dry 1,5- and/or 1,8-dinitroanthraquinone from suspensions which contain liquid nitrobenzene whereby in a first stage solid 1,5- and/or 1,8-dinitroanthraquinone with a content of less than 30% by weight of nitrobenzene is separated off mechanically from the suspension at elevated temperature and whereby in a second stage the residued nitrobenzene is removed from the separated 1,5- and/or 1,8-dinitroanthraquinone by lowering the pressure during which the temperature falls.
