Filed: 1985-03-23
Abstract: A blood pump comprises an atrium chamber defined by flexible walls and having an inlet and an outlet, a ventricle chamber defined by flexible walls and having an inlet and an outlet, a passage communicating the outlet of the atrium chamber with the inlet of the ventricle chamber, a first one-way valve in the passage adapted to permit blood flow only from the atrium chamber to the ventricle chamber, and a second one-way valve in the outlet from the ventricle chamber adapted to permit blood to flow through the outlet only out of the ventricle chamber. The chambers are movably supported in a casing having first and second openings, the atrium chamber inlet being fastened to the first opening and the ventricle chamber outlet to the second opening. A drive device cyclically moves the walls of the ventricle chamber to decrease its volume and expel blood from it while simultaneously moving the walls of the atrium chamber such that its volume may increase upon inflow of blood into the inlet to it. The drive device includes a drive ring surrounding and joined to the passage and having a surface engageable with the walls. of the ventricle chamber over a selected area such that the pressure of blood entering the chambers between driven strokes of the drive device controls the output of the blood pump by establishing the magnitude of the return stroke of the drive ring as a function of a pressure force acting over the area of engagement between the drive ring and the walls of the ventricle chamber.

Title: Circuit arrangement for the turn-off control circuit of a GTO thyristor
Inventor: TADROS YEHIA DR ING
IPC: H03K17/722
Filed: 1985-05-10
Abstract: In a circuit arrangement for controlling a GTO thyristor (V) with a pulse transformer (T) arranged in the turn-off control circuit for the GTO thyristor (V), the secondary winding (II) of which transformer is connected via decoupling diodes (D5...Dn) between the control terminal and the cathode of the GTO thyristor (V) and the primary winding (I) of which is connected to a first voltage source (E1) via a first switching element (Q2) for the entire duration (tgw) of the turn-off process of the GTO thyristor (V), a lower stray inductance of the pulse transformer (T) is to be made possible by reducing the required voltage/time area in the latter. This is achieved by the fact that the primary winding (I) of the pulse transformer (T) is connected to a second voltage source (E2), the voltage of which is connected via a second switching element (Q1) to the voltage of the first voltage source (E1) from the beginning of the turn-off process for a much shorter time (T1) than the total duration (tgw) of the turn-off process. <IMAGE>

Title: Flow regulating valve
Inventor: KOERFGEN HARALD
IPC: F16K3/08
Filed: 1985-10-31
Abstract: The invention relates to a flow regulating valve with a housing which can be inserted into fittings and in which are arranged, transversely to the longitudinal axis, a non-rotatably held valve-seat disc and a valve-regulating disc which can be rotated by means of a valve spindle, a sealing element with a supporting body being held against shoulders in the housing, between the inlet channel of the fitting and the valve-seat disc. To compensate for differing overall lengths due to relatively large manufacturing tolerances of the individual parts of the valve and to provide reliable sealing, it is proposed that a conically shaped side wall against which the sealing element rests should be formed on the upstream side of the valve-seat disc.

Title: Combustion chamber arrangement
IPC: F23C3/00
Filed: 1986-02-04
Abstract: The invention relates to a combustion chamber arrangement which makes it possible to combust fuels loaded with harmful substances or to post-combust waste gases loaded with harmful substances in such a manner that the legal conditions (e.g. with regard to dioxin) are satisfied. The invention in this case envisages that the combustion chamber arrangement is designed as a cylinder, in the casing of which, at or close to its one end, a number of inlets are arranged for the tangential introduction of all reaction substances, and at the other end of which the outlet is situated. With such an arrangement, a uniform temperature field for eliminating the dioxins can be achieved without temperature peaks arising which lead to the formation of nitrogen oxides.
