Patent DE-19606868-A1 (DE)
Title: X=ray generator for medical application
Inventor: BEYERLEIN WALTER DIPL ING
IPC: H05G1/34
Filed: 1996-02-23
Abstract: The generator includes a control circuit which is provided for the X-ray tube heating current. A correction value is provided for the desired heating current value. The correction value corresponds to the drop in the tube current for constant heating current at the start of the radiation period due to the temp. drop of the cathode. A correction algorithm uses this correction value.  The correction value delta I(heat) is calculated according to the formula delta I(heat) = I(heat) - square root (I(heat)*I(heat)) - (Itube*Pout)/(1A*Rspin) where Itube is the tube current, Pout is the release energy of the electrons from the cathode, and Rspin is the spin resistance.

Title: Prosthetic heart valve
Inventor: OTTO KARL-HEINZ
IPC: A61F2/24
Filed: 1996-04-10
Abstract: The prosthetic heart valve comprises a flap-ring (10) which has a radius R and three wing flaps (10,14,16) which lie in a ring and pivot on a swivel axis (18). The swivel axis, in the projection of the ring plane has a clearance between the ring of between 0.5 and 0.9 R. The wing flaps, when in the closed state, fit flush with the plane in which the flap-ring is situated.  The clearance of the centre of mass of a single wing flap in the open state, is less than ninety percent of the clearance from the centre of the swivel axis. The clearance of the centre of mass of a single wing flap from the centre of the ring plane in the closed state is below the theoretical plane between the swivel axis and where the centre of the ring plane lies.
