Title: Apparatus for the perfusion of (flushing) liquid in body cavities
Inventor: MEYER EDGAR
IPC: A61M3/02
Filed: 1993-09-21
Abstract: A device for the perfusion of sterile liquids in body cavities under controlled pressure comprises a disposable bag (2) which contains the liquid and is located in an intermediate solution (28) which is contained in a pressure container (1) and may be temperature-controlled. The pressure container (1) is sealed off by a stopper (3) through which a tube-like continuation of the disposable bag (2) passes. This continuation is connected via a cannula (4) and a perfusion tube (5) to a perfusion instrument (8) which can be introduced into the body cavity (9). The pressure at which the sterile perfusion liquid passes into the body cavity (9) is controlled by the pressure acting on the intermediate solution (28) in the pressure container (1) and thus on the wall of the soft disposable bag (2). <IMAGE>

Title: Method and device for driving gate turn-off power semiconductors of a resonant converter at a matched switching speed
Inventor: BRUCKMANN MANFRED DIPL ING
IPC: H03K17/04
Filed: 1993-11-03
Abstract: The invention relates to a method and a device (38) for turning on a gate turn-off power semiconductor (T1, ..., T4), which is controlled by means of an electric field, of a resonant converter (6 to 14) which is operated in the zero voltage switch (ZVS) mode. According to the invention, a check is made, before an on control signal arrives, of whether the valve voltage (uDS) of the power semiconductor (T1, ..., T4) at approximately equal to zero, a changeover being made, in the event of a valve voltage (uDS) which is not approximately equal to zero, from a turn-on operation of the power semiconductor (T1, ..., T4) at a high switching speed to a turn-on operation at a matched switching speed. Consequently, the operation of the resonant converter (6 to 14) can be maintained even in the case of a load change or malfunction of the inductor (14), without in the process overloading the power semiconductors (T1, ..., T4) of the converter (10) in terms of voltage. <IMAGE>

Title: Method for automatic process-optimal control of deep drawing on presses and corresponding deep drawing press
Inventor: LIEWALD MATHIAS DR ING
IPC: B21D22/26
Filed: 1993-11-13
Abstract: Before prodn. of deep-drawn components (2) of a given type, the inward displacement of the blank edge (8) with time (or the press stroke) is determined at least at one circumferential point during deep drawing of a faultless component. The data is stored and subsequently compared with the inward motion of the corresponding point on the current blank during the prodn. run. Dependent on the comparison result, the blank clamping force is either decreased or increased, or left unaltered. The blank clamping unit (5) or the bearing area (6) is provided with a displacement sensor whose signal is fed to a system (13) controlling the clamping force.

Title: Vacuum cylinder piston press for residual degassing of pyrolysis products and method for its use
Inventor: SCHMIDT EDWIN
IPC: C10B13/00
Filed: 1994-04-14
Abstract: Vacuum cylinder piston press for residual degassing of pyrolysis products and method for its use, in particular in thermal refuse treatment. As is known pyrolysis products from conventional pyrolysis plants are fed directly to incineration without further measures. Thermally volatile substances such as heavy metals and endothermically reacting chemical elements and compounds which have not escaped in the gaseous state with the pyrolysis gas remain in the gaseous state in the hot mass and the porous, carbonised structures of the pyrolysis products, or recondense there when the temperature decreases. At any rate, they pass into the incineration of the known negative consequences. By means of the invention these critical substances are removed by suction in the gaseous state from the pyrolysis products before incineration using a vacuum effect and they condense jointly in solution. They thus cannot pollute the incineration exhaust gases and residues. The vacuum cylinder piston press, appropriately dimensioned, can be integrated into all known pyrolysis plants, also to increase efficiency and profitablity.

Title: Electro-acoustic transducer
Inventor: FISCHER REINHARDT
IPC: H04R17/00
Filed: 1988-11-10
Abstract: An electro-acoustic transducer comprises a piezoelectric element (5) arranged on a transformer (6) and a membrane (1). The two ends of the transformer (6) facing away from the piezoelectric element (5) are connected on the one hand to the membrane (1) and on the other hand with a support (3). The transducer is characterized in that the membrane makes an angle with the transformer at the jonction between the two. This arrangement of the transducer and the piezoelectric element with respect to the support and the membrane makes it possible to achieve the full vibration capacity of the surface of the piezoelectric module and to eliminate resonance amplifications typical of piezoelectric elements, by using very small membranes.
