Abstract: CERAMIC ROTOR BLADE ASSEMBLY FOR       A GAS TURBINE ENGINE     ABSTRACT OF THE DISCLOSURE         The present invention provides an assembly for mounting a row of ceramic rotor blades in the metal rotor disc of a gas turbine engine.  The major components of the assembly comprise a well known ferritic metal rotor disc in which is mounted, in a conventional fir-tree root configura-tion, a plurality of high temperature metal alloy or super alloy intermediate members forming an annular array thereof and defining "dog-bone" shaped axial grooves in the annular face for receipt of a complementary "dog-bone" or single serration root of a ceramic blade for mounting an annular array of ceramic blades.  The root shank portion and the air foil portion of the blade are separated by a platform and centrifugal-force pins are inserted between adjacent platforms to fix the blade against low frequency vibration and to seal the gap therebetween against leakage of the motive fluid into the root area.  The rotor disc is cooled and radial passages are provided in the intermediate members to permit cooling flow therethrough to maintain the temperature gradient through the assembly.

Abstract: ABSTRACT           A method of traversing a strand between tow spaced rows of strand-restraining elements moving together in the same direction in the same plane to form a web is implemented by a pair of strand-engaging members associated with each row of strand-restraining elements for slideably engaging the strand and moving it in alter-nate traverses toward one and then the other row while forming a loop in the strand during each traverse.  The second member of the pair of strand-engaging members travels faster that the first and catches up with it as it crosses the row of strand-restraining elements.  The loop is brought into a plane parallel to the plane of the rows of strand-restraining elements.  Means are provided for disengaging the loop from the strand-engaging members and depositing the loop around the strand-restraining elements as soon as the loop is moved beyond the row of elements.

Abstract: ABSTRACT OF THE DISCLOSURE        The specification describes a drive system for rotary printing presses which is particularly useful in the web-fed rotary offset variety in series arrangement having a main drive system for the printing units and two blanket cylinders in mutual contact for each printing unit.  Each of the blanket cylinders co-operates with the plate cylinder while each plate cylinder is driven individually by the main drive system which is characterised by the fact that there are two spur gears which mesh with the spur gears of the main drive system of adjacent printing units.  Each of the plate cylinder drive gears meshes with one of the two spur gears while each plate cylinder is coupled to its associated blanket cylinder through a further pair of spur gears which is located beside the main drive system along another geared line.

Abstract: ABSTRACT OF THE DISCLOSURE           A process for recovering nickel from an impure nickel compound which contains a major proportion of nickel values and a minor proportion of other metal values which are relatively soluble in ammoniacal ammonium sulphate solution, and a minor proportion of nickel values and other metal values which are relatively insoluble in the solution.  The impure nickel com-pound is treated with ammoniacal ammonium sulphate solution so that the relatively soluble nickel and other metal values are dissolved in the solution with the relatively soluble nickel values being dissolved substantially as nickel diammine sulphate, and so that the relatively insoluble nickel and other metal values form an undissolved residue.  The residue is separated from most of the ammoniacal ammonium sulphate solution so as to provide a substantially residue-free solution of nickel diammine sulphate and relatively soluble other metal values on the one hand and a slurry of the residue of undissolved nickel and other metal values and the solution on the other hand.  The substantially residue-free solution is subjected to a reducing operation by hydrogen gas to produce precipitation of elemental nickel powder from the residue-free solution, and the elemental nickel powder is separated from the residue-free solution to produce a first nickel powder product.  The slurry is subjected to a reducing operation by hydrogen gas to produce precipitation of elemental nickel powder from the slurry, and the elemental nickel powder is separated from the slurry to produce a second nickel powder product.

Abstract: Abstract of the Invention A position determining system in which a delay element has at least one driver transducer at at least one position and at least one receiver transducer at at least one other position, the transducers being arranged so that a traveling wave signal at the driver transducer travels along the delay element from the first said at least one position to said at least one other position so that a distance which is to be measured is traversed more than once.  Certain embodiments accomplish such operation by providing a "folded" or U-shaped delay element, the driver and receiver being located on separate legs thereof so that the traveling wave traverses both legs of the delay element so that the distance which is to be measured is traversed twice, thereby increasing the resolution of the overall device.  In another embodiment, for example, a pulse is  triggered a plurality of times at at least one driver transducer means so that it traverses the distance from the at least one driver transducer means to at least one receiver transducer means a plurality of times.

Abstract: Abstract of the Disclosure Disclosed herein is an earth boring bit of other-wise conventional construction except for the bearing and cutter retention.  A snap ring is used to retain the cutter, the grooves that receive the ring and the ring construction being such that the ring is forced into the retainer groove when the cone is thrust inward.  The ring cannot therefore accident-ally return to its assembly position to permit cutter loss. This enables the use of exclusively frictional bearings and retainer means of exceptional strength and reliability.

Abstract: ABSTRACT OF THE DISCLOSURE      Mold and core rod combination for forming a plastic parison for stretch/blowing into a plastic bottle com-prising a core rod with an end mated to the mold so as to permit formation of a parison  with a flat bottom and wherein the bottom corners of the parison have a sharp taper.  The core rod is preferably shaped to include a shoulder having a substantially straight outer wall at the mouth end of the parison mold, and constructed and arranged with the mold to permit deposit of additional plastic at the inner wall of the shoulder of the parison. The design of the mated mold and core rod combination is based on the recognition that in a continuous bottle forming process a particular area of the parison can be made hotter or cooler by increasing or decreasing the thickness of that area of the parison.  Parisons formed with the disclosed mold-core rod combination permit a deeper and longer stretch of the parison without tearing or deformation of the parison bottom or deformation or wrinkling at the shoulder of the finished bottle while providing essential wall strength.
