Abstract: ABSTRACT        A high heat resistant transparency 10 of epoxy resins cured with adducts of trimethoxyboroxine and benzyl alcohol ii disclosed to resist intense heat for these transparencies in their use on military and industrial hardware.  Additionally, the transparency may include phosphite or phosphate compounds to improve heat resistance, with the phosphate compound in sufficient concentrations to delay gel times such that the phenyl substituted alkyl alcohol may be eliminated from the composition.  This transparency may exist in a composite with other layers of trans-parent material known to those skilled in the art. The epoxy transparency layer 20 is bound to the other transparent layers, 30, 40 in a variety of configura-tions, using an interlayer 35, 45 of mercaptan terminated resins.  These resins greatly improve resistance to moisture permeability in and about the edges of the entire transparency.

Abstract: HYDROCRACKING PROCESSES HAVING AN ENHANCED EFFICIENCY  OF HYDROGEN UTILIZATION                 ABSTRACT OF THE DISCLOSURE      A hydrocrackate from a hydrocracking zone operating under hydrocracking conditions is separated into at least one liquid phase and a  separated vapor phase wherein the separated vapor phase has a greater concentration of hydrogen than the minimum concentration of hydrogen in the vapor phase in the hydrocracking zone.  At least a portion of the separated vapor phase is contacted with the feed side of a polymeric membrane selective to the permeation of hydrogen as compared to the permeation of methane, and the opposite side of the polymeric membrane is maintained at a pressure sufficiently below the pressure at the feed side of the polymeric membrane to permeate hydrogen to the opposite side of the polymeric membrane and to provide a hydrogen permeate having a concentration of hydrogen greater than the concentration of hydrogen in the separated vapor phase and greater than the concentration of hydrogen in the hydrogen feed gas.  The hydrogen permeate is compressed and recycled to the hydrocracking zone.

Abstract: ABSTRACT OF THE DISCLOSURE         A tool comprises a body having coaxial portions radially defined by soil compaction surfaces of step-down radii from the sizing portion to the tool tip.  The soil-compaction surface of each portion is a cylindrical sur-face generated by a generatrix of a predetermined length extending parallel to the tool axis and bounded by two parallel helices of one and the same helix angle.  These surfaces are successively  conjugated by transition portions defined by cylindrical surface whose generatrix is parallel to the tool axis and uniformly approaches the same axis to thereby form a smooth transition from the surface of the body portion of a greater radius to that of an adjacent body portion of a smaller radius.  A method of forming a hole by the same tool is also described.  The invention is useful in making cast-in-place piles in the soft soil saturated with water.

Abstract: Abstract of the Disclosure:           In a mobile radio communication system, a control station supplies a traffic adjusting signal to a particular one of base stations, channels allotted to which are used up to a predetermined number in communication therethrough between the control station and mobile stations in the service area thereof provided that some of the channels allotted to an adjacent base station are idle.  The signal narrows the service area of the particular base station as by reducing the base station output power. Alternatively, the signal varies a communicable distance of each mobile station in the service area of the particular base station.  For example, the signal makes the particular base station raise the mobile station output power to make some of the mobile stations carry out the communication through the adjacent base station.  As a further alternative, the signal varies both the service area and the communicable distance.  For example, the signal makes the particular base station raise the reference level used in communication therethrough.  Instead, a lower reference level is developed in each mobile station for use in communication through the adjacent base station.

Abstract: ABSTRACT           A continuous feed, solid bowl centrifuge with intermittent rim discharge.  The centrifuge has first and second members mounted in fixed positions relative to each other for rotation about a common axis.          Each member has a peripheral edge portion extending about the common rotational axis with the portions being spaced from each other to create an annular gap therebetween.  A third or rim member is mounted for rotation with the first and second members about the common rotational axis. m e rim member has  a cylindrical surface extending between the peripheral edge portions of the first and second members and is dimensioned to close the gap therebetween. The rim member is supported with its cylindrical surface substantially parallel to the rotational axis of the centrifuge; and, an opening-closing mechanism is provided that maintains the cylindrical surface substantially parallel to the rotational axis as it is moved to open and close the gap.  The cylindrical surface is the only portion of the rim member exposed to the high, multi-directional fluid pressures of material being centrifuged.  In this manner, the opening-closing mechanism for the rim member does not have to work against any force components generated by the centrifuged material other than radially directed ones which are uniformly directed against the cylindrical surface and offer relatively inconsequential resistance to the movement of the rim member.          The rim opening means does not rotate with the centrifuge thereby simplifying the power transfer to it and adding no weight and imbalance problems to the rotating centrifuge.

Granted: 1985-08-13
Abstract: ABSTRACT      A process is described for the solvent refining of coal into a gas product, a liquid product and a normally solid dissolved product.  Particulate coal and a unique co-catalyst system are suspended in a coal solvent and processed in a coal liquefaction reactor, preferably an ebullated bed reactor.  The co catalyst system comprises a combination of a stoichiometric excess of iron oxide and pyrite which reduce predominantly to active iron sulfide catalysts in the reaction zone.  This catalyst system results in increased catalytic activity with attendant improved coal conversion and enhanced oil product distribution as well as reduced sulfide effluent. Iron oxide is used in a stoichiometric excess of that required to react with sulfur indigenous to the feed coal and that produced during reduction of the pyrite catalyst to iron sulfide.
