Abstract: The disclosure describes a method of attaching and electrically connecting first and second planar substrates, wherein the first and second substrates have inwardly-facing surfaces with matching patterns of bond pads. The method includes adjusting a wire bonder's tear length to a setting which leaves a projecting tail of severed bond wire at a terminating wedge bond connection. Further steps include making a wedge bond to an individual bond pad of the first planar substrate with bond wire from the wire bonder, and then severing the bond wire adjacent said wedge bond. The adjusted tear length of the wire bonder results in a tail of severed bond wire which projects from said wedge bond and said individual bond pad. Subsequent steps include positioning the first and second planar substrates with their inwardly facing surfaces facing each other, aligning the matching bond pad patterns of the first and second planar substrates, and pressing the first and second planar substrates against each other.

Abstract: The process and apparatus of the present invention enable the production of glass fiber product from scrap glass fibers. The process includes: feeding the scrap glass fibers having an average length up to around 12 inches to a glass melting tank having a pool of molten fiberizable glass, melting the scrap glass fibers without the presence of non-vitrified glass forming materials in an oxidizing environment, conditioning the melt to a formable viscosity, and forming the glass fiber from the conditioned melt where for a given glass fiber product there is a near constant pull of the melted glass from the melter. The rate of feeding of the scrap glass to the melter is sufficient to maintain the pool of melted glass with a level within the range of .+-.0.35 inch (9 mm.) over a period of eight hours. The scrap glass fibers have a similar fiberizable inorganic composition to that of the desired glass fiber product and generally include fibers with organic-containing sizes and/or coatings.

Abstract: A set of book ends removably receive dumbells. Each book end comprises a horizontal member with a stud at one end and a vertical member affixed to the horizontal member between the stud and the other end. Each dumbell comprises a short bar between two enlarged end portions, with one end portion having a cavity to mate with the stud.

Abstract: The preparation of overbased Group II metal sulphurized phenates by reacting the metal base, a sulphurized phenol or phenol sulphur mixture a diol and an alcohol in oil over a controlled temperature cycle, introducing carbon dioxide to the mixture when the temperature is less than 140.degree.C and the water present in the mixture has been reduced to below 0.3% by weight of the mixture.

Abstract: A lubricating oil composition comprising a lubricating oil base and (A) an overbased detergent additive (e.g. an organic phenate) is foam stabilised by adding thereto, (B) 0.1 to 15 wt.% based on the weight of (A) of a monocarboxylic acid, anhydride or salt thereof, or a dicarboxylic acid, anhydride or salt thereof, said acid, anhydride (e.g. a polyisobutenyl succinic anhydride) or salt having at least 30 carbon atoms per molecule or the reaction product of a phosphorus sulphide with a hydrocarbon and (C) a dihydric alcohol having 2,3, or 4 carbon atoms per molecule (e.g. ethylene glycol), or a di- or tri- (C.sub.2 -C.sub.4) glycol or an ether alcohol having 2 to 10 carbon atoms per molecule.
