Title: Multilayer optical interference coating of complex curved substrates
Inventor: LEE JAMES C
IPC: B05D7/24
Filed: 1990-10-04
Abstract: Precision multilayer optical interference coating of substrates having complex topology using complementary shaped electrodes and plasma enhanced chemical vapor deposition within a chamber. The materials for the optical quality thin films are obtained from starting reactants of the form M-R where M denotes a metal atom and R denotes an organic component. These vapor phase starting reactants are brought into a reactive atmosphere of the chamber through a plurality of orifices in one of the shaped electrodes. The resulting substances are deposited as thin films upon the substrates with inherently superior scatter loss performance because of the low temperature nature and simple direct vapor-to-solid phase transformation pith of the process.

Title: Implantable and haemodynamically responsive cardioverting/defibrillating pacemaker
Inventor: COLLINS KENNETH A
IPC: A61H31/00
Filed: 1991-01-21
Abstract: ABSTRACT A cardioverting/defibrillating pacemaker with the ability to sense and respond to haemodynamic com-promise.  The ventricular pressure (VP) and electrical activity of the heart are sensed via one or more transvenous or epicardial devices.  The filtered peak-to-peak amplitude (VFPPA) or a peak pressure function (VPPF) based upon the right and/or left VP waveform(s) are derived.  In one embodiment the VP and the elec-trical activity of the heart are sensed and processed continuously, and the VFPPA or the VPPF continuously derived.  The VFPPA or the VPPF, and the ECG are used to initiate bradycardia pacing, antitachycardia pacing and cardioversion/defibrillation therapies.  In anoth-er embodiment the VP and electrical activity of the heart are continuously sensed.  The electrical activi-ty is processed continuously and used to determine whether or not some irregularity exists.  If so, one of the VPPF or  VFPPA is derived and used to decide which of the therapies are to be used.  One of the VPPF or VFPPA is also periodically determined to en-sure optimal haemodynamic function.  In both embodi-ments the degree of haemodynamic compromise is deter-mined by comparing the derived VFPPA or VPPF with programmed values.  An algorithm maximizes the effec-tiveness of support pacing.  Preferably an ECG trans-venous sensor in the right atrium and a combined ECG/VP sensor in the right ventricle are used.

Title: Box for removing and containing hypodermic needles
Inventor: ARGUESO GAMA FRANCISCO J
IPC: B65D47/28
Filed: 1991-06-04
Abstract: ABSTRACT       The box has the shape of a conventional closed container (1) with a hole (3) in its top part, over which it is possible to place opposite it another hole (4) belonging to a cover (2) mounted on the top in a sliding manner with regard to the body (1) of the container or box.

Inventor: JONKER GARY D
IPC: F02P17/08
Filed: 1991-08-01
Abstract: A digital engine analyzer has an oscilloscope display and is controlled by microprocessors operating under menu-driven stored program control. The analyzer receives analog input signals from an engine being analyzed, engine identification and parameter data entered via a keyboard, function and mode data selected by keyboard, and data communicated from an engine on-board computer via a hand-held scanner device. The analyzer calculates and displays spark plug burn time information derived from a single analog input signal, a historical display of peak ignition voltage values for a selected cylinder over a number of engine cycles and real time cylinder time balance information. Peak capture circuitry permit the display of a full cylinder period of a waveform, even though it contains very high frequency portions, by selectively switching between normal and high resolution modes. The scanner interface permits the scanner control functions to be effected from the analyzer keyboard.

Title: Plasma spray apparatus for spraying powdery or gaseous material
Inventor: LANDES KLAUS
IPC: H05H1/34
Filed: 1992-02-13
Abstract: The plasma spray gun contains an indirect plasmatron for generating a long arc, having a plasma channel (4) between the cathode arrangement (1, 20) and the anode ring (3). The cathode arrangement has a central insulation body (21) which projects into the cavity (22) of an inlet nozzle (5) of the plasma channel (4). The plasma gas is introduced into the inlet nozzle (5) through an annular channel (23) between the insulation body (21) and the nozzle wall. A plurality of rod-shaped cathodes (1) which are embedded in the insulation body (21) run parallel to one another and are arranged distributed in the circle around a central axis (2) whose active ends (63) project out of the insulation body (21) into the nozzle cavity. The spray material (SM) is supplied to the cathode-side end of the plasma channel (4) through a tube (24) which extends along the central axis (2) through the insulation body (21) and opens into the nozzle cavity, the cathode ends (20) projecting beyond the mouth (25) of the tube. By means of a high energy concentration in the nozzle cavity, energy is supplied to the spray material in this region and through the long arc along the entire plasma channel, so that the spray material emerges from the gun in the fused state with high acceleration. The anode ring has no nozzle function and can therefore be wide enough for the spray material not to impinge on it. <IMAGE>
