Title: Bioactive vitreous composition for bone implants, filaments made therefrom and method
Inventor: VITA FINZI ZALMAN EMILIO
IPC: A61L27/00
Filed: 1991-02-04
Abstract: The invention relates to a bioactive vitreous composition for bone implantation which includes the following approximate percentages by weight of the following oxides: SiO2 from 40 to 55 %;  P2O5 from 5 to 8 %; Cao (MgO) from 20 to 40 %; Na2 (K2O) from 20 to 30 %. The composition can be reduced to filaments without becoming ceramic by virtue of the addition of a total of not more than 9 % by weight of K2O and Al2O3, the percentage of Al2O3 being from 0.5 % to 2.5 %. The filaments thus obtained can be used to prepare products for bone implantation in the form of bundles of filaments, gauzes, nets or other fabrics, felts, "cotton-wools" and the like. The filaments can be reduced to particles of powders for the application, inter alia, of a coating layer of the vitreous composition to a permanent metal prosthesis.

Abstract: 6120-12 CN/slb INTERACTIVE PROTECTIVE SYSTEM                       ABSTRACT An interactive protective system to protect an individual from exposure to a dangerous condition associated with the operation of equipment such as but not limited to machinery and the like. The system comprises a protective garment adapted to be worn by the individual. The protective garment includes a sensor for sensing when the protective garment is being worn and a signalling device responsive to the sensor for generating a signal indicating when the protective garment is being worn. A detector and control device responsive to the signal from the signalling device triggers an alarm sensible to the individual when it is activated by the motion sensor and does not sense the signal from the signalling device. A detector and control device responsive to the signal from the signalling device is operatively associated with the equipment to render the equipment inoperative in the absence of the signal and render the equipment operative only when the detector and control device detects the presence of the signal. In addition, one or more sensors may be located on or surrounding a dangerous condition to anticipate when an individual is approaching a hazard zone associated with the dangerous condition and then arm an alarm and activates an interactive protective system which protects an individual from exposure to the dangerous condition. The detector and control device trigger an alarm sensible to the individual.

Title: Current leakage control for electrosurgical generator
Inventor: MCELHENNEY JAY J
IPC: A61B/
Filed: 1991-09-24
Abstract: A current leakage control circuit regulates the output power of an electrosurgical generator to limit the amount of leakage current. The leakage current is monitored with a differential transformer which has the output and return leads of the electrosurgical generator as first and second windings. A third or sense winding produces a control signal whenever the currents in the output and return leads are not equal, thus indicating current leakage. The control signal is compared to a predetermined maximum safe level of leakage current. If this predetermined level is exceeded, a power control feedback loop of the electrosurgical generator reduces the output power to a sufficiently lower level to reduce the leakage current within a maximum acceptable limit.

Title: Stirling engine with heat exchanger
Inventor: WEBER ECKHART
IPC: F02G1/043
Filed: 1993-05-21
Abstract: Abstract There is a Stirling engine in  which a displacer plate 5 is movable to and fro between two housing plates 1, 2 and is free of sliding friction along the periphery with respect to the end faces 10 of the housing.  Here, it is desirable for the Stirling engine to be designed for increased output ranges with a reduced complexity of construction, in that the housing plates and the displacer plate are made as large as possible while taking into account the compressive strength of the housing.  This is achieved in that the two housing plates 1, 2 are held spaced from one another by distributed struts 3, the struts, which run perpendicular to the displacer plate 5, passing there through, and in that the displacer plate 5 is guided with respect to the housing end faces 10 along its end edges by linear roller diaphrams 9.  The housing plates are stabilized over their surface with respect to one another by the struts, and the displacer plate is guided precisely parallel by the roller membranes with respect to the struts.

Title: Computer simulation of live organ
Inventor: BEAVIN WILLIAM C
IPC: G06F19/00
Filed: 1993-12-23
Abstract: A computer system receives two dimensional slice data of a heart or other organ to be simulated in three dimensions. It also receives chemical composition data of the heart or other organ, and chemical composition data other parts of the body.      These data are put in the computer memory. Then a Voxel View or three dimensional volume rendering program forms images of the organ to be studied. For example, with the heart it generates images of the atria and ventricle. Diagnostic data obtained from a patient conveniently with electrical measurement signals including an electrocardiagram, electromyogram, electroencephalogram, and other diagnostic measured electrical signals obtained from a patient are fed into the system and are placed in computer memory. Physiological data of the patient, including the strength, weakness and other parameters of the organ is also considered diagnostic data and is supplied into the system. This can be done manually with a keyboard or mouse, or may be supplied from a hard disk, a floppy disk or a tape. This is also fed into memory and is used to modify the three dimensional image data of the organ. This data is then synchronized with the electrical signal diagnostic data.      Conveniently the first derivative of the electrical data signal is taken, and P and Q waves determined from the derivative. From this information the organ, including sub-parts, may be simulated. This data may be fed in black and white or preferably in color to a device which shows the organ for visualization, operation simulation, or training.
