Abstract: A process for preparing dried grapes which are further processed to remain desireably soft with minimal color, flavor, or textural changes over extended periods of time. The process combines the use of enzyme inactivation and a hydrophillic carbohydrate infusion into fresh grapes, followed by drying the grapes to a moisture content of less than 30%. The dry grapes are then converted into simulated raisins by storing the dry grapes for a period of time under controlled humidity and at an elevated temperature effective to provide a darkening in color and to develop a natural raisin-like flavor within the grapes without further drying of the grapes.

Abstract: A flavoring composition of 2-(.alpha.-mercaptoalkyl)-3-thiazoline when added to foodstuffs imparts or augments a meaty, sauteed onion flavor and aroma.

Abstract: A mining apparatus and method for dislodging material from a mine face. The dislodged material is transported from the front to the rear of the mine for further handling. The apparatus has a lifting mechanism for raising cross beams to the roof of the mine wherein beam jacks are permitted to engage the cross beams to provide support to the mine roof. The temporary roof support permits advancement of miner as dislodged material is removed.

Abstract: A mining method and bolting apparatus. Material is dislodged from a mine face by means of a miner wherein the face is advanced. The dislodged material is transported from the mine face for further handling. A temporary roof support of cross beams supported by beam jacks is provided. A bolting apparatus installs bolts in the mine roof providing a permanent roof support. Cross beams and beam jacks are lowered, manually moved forward and reinstalled wherein the temporary mine roof support is advanced. The mining apparatus and bolter is advanced under the advanced temporary roof support to the advanced mine face.

Abstract: This invention pertains to a video disc having a conductive bilayer thereon of a copper layer and a nickel/chromium/iron alloy layer wherein the alloy layer contains oxygen which decreases in content from the copper-alloy interface to an alloy-dielectric interface.

Abstract: This invention relates to a capacitive recording means comprising a video disc with a thin conductive bilayer on the surface of the disc wherein the bilayer is a first layer of copper and a second layer of an alloy of nickel, chromium and iron which contains oxygen. An inorganic dielectric layer is disposed on the conductive layer.

Abstract: This invention relates to a video disc with a thin polymeric dielectric layer formed from styrene and nitrogen. The dielectric layer has improved age deterioration resistance, wear characteristics and adhesion to a metal conductive layer.

Abstract: A contact for a silicon device comprises a layer of gold on the silicon, and a layer of cobalt on the gold layer. The contact is made by depositing gold on the silicon, depositing cobalt on the gold and heating the structure at a temperature between about 300.degree. and about 370.degree. C in a reducing gas atmosphere.

Abstract: This invention relates to a photoresist consisting of a novolak resin and a sensitizer containing a thiodipropionate compound.

Abstract: An optical waveguide of niobium-doped lithium tantalate single crystal has excellent low loss waveguiding properties with strong electro-optic behavior. The waveguides are made by depositing a film of niobium on a polished lithium tantalate crystal, annealing the crystal so as to diffuse the niobium into the crystal and cooling the crystal.

Abstract: Permanent thin-phase holograms are recorded wherein the recording medium contains a recording layer comprised of an olefinically unsaturated negative photoresist polymer containing an .alpha.-diketone.
