Abstract: Abstract of the Disclosure Bituminous sands are intimately contacted with an aqueous medium containing a catalytically effective amount of a novel catalyst to separate the bitumin at temperatures below the decomposition point of valuable hydrocarbons contained therein. Usually the temperatures of separation are not higher than 100°C and preferably are about 40-90°C.  The catalyst has the unique property of enabling the aqueous medium to penetrate the bituminous sands and, in a manner not fully understood at the present time, rapidly break the bonds between the bitumin and the sand particles and alter the surface properties and/or characteristics thereof whereby the bitumin and sand particles may be easily separated.  The separated bitumin fraction floats to the surface of the aqueous medium and may be removed therefrom by scimming, decanting, floating off, or other suitable techniques.  In instances where bituminous sands are weathered and/or the bitumin is in an oxidized or polymerized form, a more complete separation may be obtained by adding a water insoluble organic solvent having a specific gravity less than that of the aqueous medium.  The resulting organic solvent layer dissolves the separated bitumin floating on the aqueous medium and the bitumin solution may be separated and distilled to recover the bitumin content.  Valuable organic acids such as humic acids and asphaltic acids may be recovered from the used aqueous medium by precipitating with an inorganic acid and recovering the precipitated acids by filtration.  The catalyst used in practicing the present invention may be prepared by steps including admixing a water soluble alkali metal silicate with an aqueous medium containing carefully controlled amounts of dissolved water soluble substances which are sources of calcium ion and magnesium ion, reacting the same to produce an aqueous colloidal suspension of the reaction product, admixing a micelle-forming surfactant with the aqueous medium, and agitating the aqueous medium containing the colloidal particles and surfactant to form catalyst containing micelles.

Abstract: Abstract of the Disclosure A one-piece reusable closure for home canning.  The closure is adapted for sealing home canning containers, such as "Mason Jars."  The closure has a one-piece threaded cap with a bonded annular closed-cell foam gasket at the periphery of the central cover panel positioned to seal against the jar lip.  A central cover portion is dished outwardly and moves to an inwardly dished configuration when vacuum is developed in the container.  When the closure is unscrewed, the central panel portion springs with an audible click to the outwardly dished configuration.  Limiting projections extending down-wardly into the gasket bear and compress the gasket material against the lip of the jar to control tightening of the clos-ure on the jar so that, when the jar contents are heated, gases will be vented under the circumferentially spaced por-tions or the gasket.  The closure may be initially fully tightened and need not be further tightened after heating and subsequent cooling of the jar to maintain the seal and, vac-uum within the container.

Abstract: Application for Patent of CARMEN D. BURNS    for GANG BONDING INTERCONNECT TAPE FOR SEMICONDUCTIVE        DEVICES AND METHOD OF MAKING SAME                    ABSTRACT OF THE DISCLOSURE     A gang bonding interconnect tape, for use in an automatic bonding machine for gang bonding of semiconductive devices, is fabricated by forming a row of first locator holes along the marginal side edge of an elongated master tape.  Next the master tape is coated with a photoresist coating and exposed, through a mask, to patterns of optical radiation to which the photo-resist is sensitive.  The mask is indexed to the locator holes in the master tape.  The mask includes patterns corresponding to parallel rows of interconnect lead patterns and to parallel rows of sprocket holes for locating each of the individual interconnect lead patterns in the gang bonding machine.  The exposed master tape is then developed, the photoresist material removed to expose the tape material in accordance with the developed images.  The exposed tape is then etched to form the parallel rows of metallic interconnect lead patterns and their respective parallel rows of sprocket holes. The master tape is then slit into a plurality of tapes.  Each resultant tape has a row of virgin sprocket holes and a row of interconnect lead patterns.  In this process, the sprocket holes for each resultant tape arc indexed to the respective interconnect lead patterns via the mask, whereas the mask is indexed to the tape via the first locator holes formed along the marginal side edges of the master tape.  The resultant tapes arc utilized in a automatic gang bonding machine in the conventional manner.

Abstract: TITLE:  CALF ROPING TRAINING AID                    Abstract of the Disclosure A training aid for calf roping comprises a calf shaped body supported by horizontal and upright skid runners.  The runners hold the body above ground to be pulled along as a roping target for a calf roper.  The calf shaped body includes a head portion that is tapered smoothly from a forward body end to a nose end.  When a loop from a lariat is passed over the head and pulled rearwardly, the body will respond by rocking rearwardly.  As the body rocks rearwardly, the head moves from a forward position to a rearward position wherein the nose end points rearward and the body rides on the upright skids.  The loop is then released as it slides rearwardly over the tapered head. Once the loop has been released, a continued forward pulling force against the body will rock the body back into a normal position.

Abstract: ABSTRACT OF THE DISCLOSURE This disclosure describes apparatus for generating electrical signals which simu-late the signals actually use by most sonar systems to indicate direction from with the sounds are received. In many passive sonar systems, arrays of hydrophones receive underwater signals from a number of sources. To indicate the direction of the sources from the receivers, the signals are manipulated so that they form, in effect, an axis along which the source of maximum amplitude lies. The equipment for performing this operation is contained in most sonar systems, and the simulation of such equipment is an expensive one. Therefore, this  apparatus operates under the control of a simulation computer to generate signals which have the direction characteristics of signals received by hydrophone arrays and which have been formed into two theoretical beams, one of each side of the axis of maximum amplitude. The apparatus of this invention includes beamformers for each of the sound sources to be simulated, all under the control of the computer.
