Abstract: The present invention is directed to methods for producing substrates for electric circuits, particularly ultra high frequency circuits, and electric components for mounting thereon employing for the purpose mixtures of polymers and finely powdered filler materials, the latter having specific electric characteristics, such as dielectric constant and/or resistivity. Any one substrate or component can be manufactured to have at least two body regions, and even multiple body regions, each of which has a different characteristic such as dielectric constant or resistivity. The regions can be formed separately as substrate or component preforms and thereafter placed together in a mold and united into a single body by a heating and pressing operation that at least melts polymer at the junctions to bond them together. If necessary, the heat and pressure conditions are such as to melt the polymer and force it uniformly into the interstices between the filler particles to form a strong, unitary body.

Abstract: Composite materials, particularly those that are highly filled, e.g. comprising about 60 to 70 volume % of finely powdered filler material in a polymer matrix, are made by dissolving the polymer in a volatilisable solvent and forming a homogeneous mixture of the components by high shear mixing. The solvent is then removed while maintaining complete homogeneity in the mixture by evaporating much of the solvent in a high shear mill, then extruding an extremely thin film or tape (e.g. 0.0125 mm (0.0005 in)) from which the remaining solvent is removed by heating without introducing any appreciable non-uniformity, such as bubble holes. Required bodies are formed from the dried film or tape by stacking the thin coherent layers, typically about 6 to 120, then heating and pressing the stack in a mold melting the polymer, uniting the separate layers and dispersing the melted polymer into the interstices between the filler particles.

Abstract: Methods and apparatus for processing materials employ two cylindrical members, one mounted within the other, defining an annular processing chamber. Preferably, the outer member is stationery (stator), while the inner rotates (rotor). The radial spacing between the stator inner surface and the rotor outer surface is equal to or less than the back-to-back radial thicknesses of the two laminar boundary layers formed on the two surfaces by the material being processed. The surfaces are made smooth, as by buffing to a finish of not more than 10 microinches. This structure inhibits formation of Taylor vortices in the processing passage, which cause unstable flow and consequent incomplete mixing. Preferably, the relative velocity between rotor and stator surfaces is at least 1.2 meters per second. The surfaces may be coated with catalysts. Transducers may be provided to apply processing energy, such as microwave, light or ultrasonic waves, through the stator wall.

Abstract: A reactor produces a gas-in-liquid emulsion for providing increased interfacial contact area between the liquid and the gas for improved reaction of the gas with the liquid, or more rapid solution or reaction of a difficulty soluble or immiscible gas in or with a liquid. The reactor is suitable for a continuous or batch type process. Rotor and stator cylindrical members are mounted for rotation relative to one another and have opposing surfaces spaced to form an annular processing passage. The gap distance between the opposing surfaces and the relative rotation rate of the cylindrical members are such as to form a gas-in-liquid emulsion of the gas in the liquid. The liquid and gas pass through the processing passage, changing into the gas-in-liquid emulsion.

Also disclosed arc formulations for three-layered polymer composite materials and surface scaling coatings, which are used in monolithic formation of receptacles or containers of electrolytic cells.

Abstract: Apparatus and methods for recording and projecting images on curved screens in a manner that imparts to an audience a sense of immersion in the projected scene. The screen is usually a segment of a spherical dome, with a large portion of the segment located below the horizontal viewing line of an audience. During recording of the images, the camera lens longitudinal axis is maintained in a substantially horizontal orientation. During projection, the projector lens longitudinal axis is maintained in a substantially horizontal orientation, and the image is positioned on the screen by horizontal and/or vertical movement of the projector lens relative to the film. The image is projected to appear to the viewer to be in substantially the same position as it was to the camera lens during recording.

Abstract: A window allows the introduction of radiation energy into an annular processing chamber filled with a material to be processed. The chamber is formed from coaxial cylinder members rapidly rotating relative to one another. The chamber can be thin enough so that it is short compared to the penetration depth of the radiation through the material, providing even exposure of the material to the radiation. Also, eddies created in the material by the relative rotation enhances the even exposure. When the material inside the annular processing chamber is opaque, resulting in an insignificant penetration depth, the eddies still insure that the material is evenly exposed to the irradiation.

Abstract: A micro-optical switch including a flexureless magnetic micromirror hinged centrally over a pin, cone or the like. The pin, cone or the like allows the micromirror to rapidly switch or tilt into a plurality of predefined positions as accurately controlled by an microelectromagnetic assembly. A liquid surrounds the pin or cone, connects the bottom of the surface of the mirror with the substrate supporting the pin or cone, and provides a capillary force holding the mirror onto the pin or cone. The liquid low vapor pressure also dissipates heat generated by the fiberoptic beam reflecting off the top surface of the micromirror.

Abstract: A replacement device for resurfacing a joint surface of a femur and a method of making and installing such a device is provided. The custom replacement device is designed to substantially fit the trochlear groove surface, of an individual femur. Thereby creating a “customized” replacement device for that individual femur and maintaining the original kinematics of the joint. The replacement device may be defined by four boundary points, and a first and a second surface. The first of four points is 3 to 5 mm from the point of attachment of the anterior cruciate ligament to the femur. The second point is near the bottom edge of the end of the natural articulatar cartilage. The third point is at the top ridge of the right condyle and the fourth point at the top ridge of the left condyle of the femur.
