Granted: 1986-04-15
Abstract: ABSTRACT         A stereoscopic picture system is described including a stereoscopic camera for picking-up a stereo-pair of images, a stereoscopic recorder, a stereoscopic encoder to selectively color each image of the stereo-pair and to superimpose them, a stereoscopic transmitter, a stereoscopic color display and a stereoscopic color viewing device.  Each image of the stereo pair in a color film system is selectively colored, or each is electronically colored in a color video system, to insure that the images are channeled separately through the color system to appear as two differently colored images at the display.  Chromatic viewing devices, such as colored anaglyph glasses, are used by each viewer to channel one image to each respective eye.  The viewer normally perceives a substantially black-and- white stereoscopic picture; however, a system for picking-up, recording, transmitting, reproducing, and viewing a full color picture is also described.  The invention relates particularly to television, but has applications to graphic and visual displays and to film and motion pictures.

Abstract: ABSTRACT OF THE DISCLOSURE      An improved method of making a carbon composite product wherein a fabric comprised of oxidized or otherwise stabilized polyacrylonitrile fibers is heat treated and then coated with a closely controlled amount of a carbonaceous binder such as a polyimide resin.  The fabric is then further heat treated to thermally fuse the resin to the fabric to form a rigid, easily handleable material.  The carbonaceous binder is applied to the fabric in a manner whereby substantial encapsulation of the individual fibers is avoided.  Next the material is cut into swatches of a predetermined size and shape and the segments are arranged into a basic or starting substrate having a volume greater than the desired volume of the end product. The basic substrate thus formed is then subjected to controlled temperatures and pressures to form a shaped substrate having a known fiber volume, a high degree of open porosity and a shape substantially corresponding to the shape desired of the end product.  During this step, the fiber volume of the substrate is adjusted and the segments are fused together to temporarily hold them in position within the substrate.  The shaped substrate thus formed is then pyrolyzed to form a carbon fibrous substrate which is densified in a freestanding configuration by the deposition of pyrolytic carbon interstitially thereof to form the desired end product.  Because the portions of the fibers which are not encapsulated with binder are free to move, stresses generated in the substrate during pyrolyzation due to material shrinkage and the like are effectively distributed.

Abstract: ABSTRACT       Hydraulic control apparatus serves to operate roof support props of a mineral mining installation and employs a manually-operable main valve device which can be set to various positions to selectively connect fluid pressure and return lines to the working chamber of at least one associated prop to thereby cause extension and retraction of the prop.          A pressure-relief valve device is connected to the particular prop chamber charged with pressure fluid by the main valve device to effect extension of the prop.  The relief valve device is automatically set by pressure control means to respond to a significantly higher pressure whilst the prop is actually being extended and set by the main device and reverts back to its normal response pressure once the prop is set.

Title: Low temperature process for depositing epitaxial  layers
Inventor: PETERS JOHN W
IPC: C30B29/16
Filed: 1983-06-21
Granted: 1986-02-25
Abstract: ABSTRACT     In certain semiconductor devices, an epitaxial layer of an oxide or sulfide, in which the crystal orientation is induced by the substrate, provides improved electrical and optical properties in the device.  The formation of epitaxial oxide or sulfide layers requires high temperatures or generates charged particles or high energy radiation that damage the substrate and prevent optimum electrical performance of the device.  This problem is overcome by exposing the substrate (20) at a low temperature to a chosen vapor phase reactant (from chamber 26) in the presence of neutral, charge-free oxygen atoms or sulfur atoms to produce a reaction between the atomic species and the vapor phase reactant to form the desired oxide or sulfide and induce the crystalline growth thereof as an epitaxial layer on the surface of the substrate (20). The atomic oxygen or the atomic sulfur is formed at a low temperature by the photochemical dissociation of a selected oxygen-containing precursor or a selected sulfur-containing precursor, respectively, (from chamber 28) by radiation of a selected wavelength (from means 16).  Epitaxial oxides, such as epitaxial zinc oxide on a sapphire substrate, are useful for forming active optical waveguide structures and active acousto-optical devices.  An epitaxial sulfide, such as lead sulfide on a silicon substrate, is useful as the active element in infrared detectors and infrared charge-coupled devices.

Granted: 1986-08-12
Abstract: ABSTRACT        Mechanical arrangements with primary application to single-acting, multiple-piston, Stirling-cycle machines pro-viding a dramatic reduction in mechanical complexity and production cost.  Two specific new machines are disclosed in detail, a single-acting, two-piston "ducted axle" machine and a quasi double-acting, four-piston, "drum cam" machine.  A power level control subsystem inherent in the ducted axle machine permits engine output to vary from maximum positive through zero to maximum negative under full load conditions by means of the simple rotation of a single moving part.  New thermodynamic working fluids are disclosed which have a higher dynamic heat transfer coefficient than either hydrogen or helium and are both chemically inert and easily liquefied.          A different power level control subsystem for Stirling-cycle prime movers based on the thermophysical properties of these fluids greatly simplifies changing the average system working pressure.  A new construction of the Stirling regenerator employs the anisotropic properties of materials such as pyro-lytic graphite to achieve superior performance.  Advantageous specific applications of copper matrix composites, manganese-copper alloys, and structural ceramics are disclosed.

Abstract: DISSOLUTION OF METALS UTILIZING .epsilon. -CAPROLACTAM                           ABSTRACT           Improved metal dissolution rates are obtained when using a solution containing sulfuric acid, hydrogen peroxide and a cata-lytic amount of .epsilon. -caprolactam.           The present invention relates to the dissolution of metals in an aqueous bath containing sulfuric acid and hydrogen peroxide, and in particular to a novel bath composition capable of effecting the dissolution at high rates.  In one specific aspect the invention is concerned with etching of copper in the production of printed circuit boards.                   BACKGROUND OF THE INVENTION           As is well known in the art, in the manufacture of printed electronic circuits a laminate of copper and etch resistant material, usually plastic, is used.  A common method of obtaining the circuits is to mask the desired pattern on the copper surface of the laminate with a protective resist material, which is imper-vious to the action of an etch solution.  In a subsequent etching step, the unprotected areas of the copper are etched away, while the masked areas remain intact and provide the desired circuiting supported by the plastic.  The resist material can be a plastic material, an ink or a solder.         In the last few years, the industry has more and more turned to hydrogen peroxide-sulfuric acid systems for etching the electronic circuit boards, due to the low cost of the etching solu-tions and to the relative ease with which copper values can be recovered from the spent etch solutions.
