Abstract: A protective, biocompatible coating or encapsulation material protects and insulates a component or device intended to be implanted in living tissue. The coating or encapsulation material includes a thin layer or layers of alumina, zirconia, or other ceramic, less than 25 microns thick, e.g., 5-10 microns thick. The alumina layer(s) may be applied at relatively low temperature. Once applied, the layer provides excellent hermeticity, and prevents electrical leakage. Even though very thin, the alumina layer retains excellent insulating characteristics. In one embodiment, an alumina layer less than about 6 microns thick provides an insulative coating that exhibits less than 10 pA of leakage current over an area 75 mils by 25 mils while soaking in a saline solution at temperatures up to 80.degree. C. over a three month period.

The other clutch part has at least two friction disks which are stiff in the circumferential direction and axially flexible in the manner of a diaphragm and are connected with this other clutch part so as to be fixed with respect to movement and rigid and are arranged on both sides of the pressure disk.

Abstract: A power supply or inverter circuit is provided for regulating power to electroluminescent lamps over a range of lamp sizes. The power supply may have an AC and/or DC input and includes at least one switch having a power input to be coupled to an electrical power source, a control input, and an output to be coupled to an electroluminescent lamp for being switched on and off to generate a drive signal to the lamp having a predetermined constant frequency and current level that is selectable over a range of frequency and current levels. A constant current mode controller has a control output coupled to the control input of the switch for turning the switch on and off so as to maintain a constant current level and frequency of the drive signal to the electroluminescent lamp substantially over its operating life. The voltage applied to the lamp is allowed to increase to a predetermined voltage limiting value in order to provide compensation due to aging of the lamp.

Abstract: Instead of applying the maximum cooling effect that can be produced, the method and apparatus disclosed applies only a carefully controlled cooling that is adequate to maintain the fluid in the pipe in a frozen condition but which maintains the temperature high enough to prevent damage to the metallurgical structure of the pipe. At the same time, the apparatus creates permanent documentation of the temperatures at selected stations along the pipe throughout the process, thereby providing proof that the pipe sustained no thermal damage.

Abstract: Disclosed herein are copolymers of tetrafluoroethylene and n-alkyl trifluorovinyl ether which further contain either curesite repeat units and/or iodine. Such curesite repeat units, upon exposure to free radicals, may crosslink the copolymers. The iodine is introduced by carrying out free radical polymerization in the presence of an organic iodide chain transfer agent. The polymers according to the invention are especially useful as elastomers and/or as molding resins for articles or parts that may be exposed to a basic environment. The preparation of such polymers by aqueous emulsion polymerization is also disclosed.

Abstract: Tuned optical filters, filter systems, and methods for tuning filters make use of a tilted filter rotated about an oblique axis of a collimating lens or other structure. This rotation varies an angle of incidence of an optical signal directed at the filter at an oblique angle to the axis of rotation. Very fine adjustments of optical filters such as for tuning a first narrow band pass filter to match a center wavelength of another narrow band pass filter, can be provided with small angles between the axis of rotation and a normal to the filter surface, and also between the axis of rotation and the optical path for the incident light. Mechanical adjustment to the filtering frequency is facilitated by making use of a rotational motion about the axis of a GRIN collimating lens.
