Abstract: ABSTRACT OF THE DISCLOSURE       A plastic underdrainage tube of generally reticular configuration formed by extruded plastic material is disclosed.          The tube is comprised axially spaced relatively thick annular bands to reinforce or impart to the tube a high stability against surrounding pressures, and circumferentially disposed longitudinal strands in thicknesses less than those of said annular bands.  These longitudinal strands are closely spaced along the circumference of the tube to form drainage openings between the circumferentially adjacent strands, the openings being disposed across the entire periphery and length-wise of the tube to allow water inflow over the entire wall portion thereof.  Each of said strands is blended into or in-tegrally joined at its intersections to the annular bands so as to be mechanically supported by said annular bands of reinforcing members, thus improving the overall strength of the tube to withstand the surrounding pressure while requiring the amount of plastic material to be used at a low level.          In another embodiment, longitudinal strands are formed in sinuously corrugated configuration and blend at their valley portions into the annular bands to define the drainage openings between the ridge portions of the adjacent strands.  The external forces acting on the ridge portions can be spread or decentralized by the corrugation of the strands and supported by the adjacent annular bands of reinforcing member.

Abstract: ABSTRACT OF THE DISCLOSURE     A self-aligning fuel nozzle assembly is provided for maintaining the alignment of a swirler member and a fuel nozzle upon displacement of the combustor liner relative to the combustor housing of a combustion chamber assembly in a turbine engine.    The self-aligning fuel nozzle assembly mounts the swirler member to the combustor liner by a de-vice having six degrees of freedom including a ball and socket joint which is placed within a structure so as to permit movement in the three main Cartesian directions of a rectangular axis system.  The combustor liner is installed within the combustor housing in such manner that the fuel nozzle is slidably received within the swirler, with the swirler being biased against the fuel nozzle by a helical spring member forming part of the assembly.  The self-aligning fuel nozzle assembly re-duces the development of local stresses between the swirler and the fuel nozzle so that wearing between these parts is reduced.  The swirler member and fuel nozzle are re-tained in aligned positions so that the self-aligning fuel nozzle assembly promotes improved fuel economy in the engine.

Abstract: ABSTRACT            A transformer or reactor has at least one sheet winding built up of several turns, wound on top of each other, of a sheet comprising a metallic foil and at least two polymer films.  The polymer films comprise, embedded therein, homogene-ously distributed grains of an inorganic filler, and both sides of the polymer films are provided with irregular elevations so that spaces exist between confronting surfaces of metal foil and polymer film and confronting surfaces of polymer films.          The spaces communicate with the space outside the end surfaces of the sheet winding, thus obtaining a complete impregnation of the sheet winding with insulating fluid or insulating gas The filler reduces the risk of contaminating metallic particles causing short-circuit between turns of the metal foil and the risk of the predetermined distance between the turns of the metal foil being changed.

Abstract: ABSTRACT Apparatus for applying surgical clips to tissue includes a self-contained supply of clips and is constructed to apply those clips, one at a time, through movement of the thumb and fingers of one hand. The clips are stored inside a sleeve along the length of the instrument, are fed into jaws at the distal end of the instrument, and are closed about tissue by a camming action produced by moving the jaws relative to the sleeve and camming them shut.  An actuating and sequencing section controls feeding and clip deformation, and guarantees that the instrument is operated only in the proper sequence so as to avoid jamming.

Abstract: UNITED STATES PATENT APPLICATION of Donald Silberstein and Andrew McMurtrie for CIGARETTE FILTER     ABSTRACT OF THE DISCLOSURE     A filter for a cigarette includes a porous filter rod circumscribed by a non-porous or air impermeable wrapper, and ventilating air grooves embedded in the wrapped filter rod which extend from one end of the filter rod a preselected distance generally longitudinally thereof.  The end of the grooves are recessed a predetermined distance or depth inwardly of the end of the filter rod and communicate with radially extending open channels formed in the one end of the filter rod.  An air permeable tipping material circumscribes the wrapped filter rod which provides a path for ventilating air flow into the grooves.   Due the the air impermeable wrapper, the air flowing in the grooves is segregated from the smoke flowing through the filter rod so that ventilating air is the only substance flowing in the grooves.

Abstract: A B S T R A C T              RADIATION EMITTING APPARATUS      A modulated optical radiation beacon, e.g. a flashing light beacon or an IR emmissive missile jamming source, can comprise a radiation source and two relatively movable apertured masks which, as the apertures thereof move into and out of registration, pass or block the radiation from the source.   Herein, to improve the uniformity of the polar distribution of the emitted radiation (assuming, of course, that a uniform distribution is required) or, in other cases, simply to improve efficiency, the apertures of the 'inner' mask, i.e. the one nearest the source, are bounded by curved reflective surfaces defining an optical cavity which at least crudely images the source at a position near the outer mask.   Advantageously, the optical cavities are defined by a spaced array of prismatic members having appropriately curved facing surfaces.

Abstract: Abstract of the Disclosure The dynamic properties of a machine are defined by its kinetic energy, potential energy and dissipation functions.  The machine is also identifiable by means of the nonviscous friction therein.  These properties form the basis for the dynamic analysis of any machine.  when the response of a single degree of freedom machine is observed while being driven by a forced periodic input torque, information is obtained whereby these functions together with the nonviscous friction characteristic may be determined.  The apparatus and method by which such determinations may be made have applications in machinery development, quality control and diagnosis.

The effluent stream from the first reactor containing vapor and liquid fractions is first cooled against a vapor stream and then further cooled against a suitable external fluid, then is phase separated to provide vapor and liquid fractions.  The separated vapor fraction is reheated against the first reactor effluent stream and passed at an intermediate temperature into the second reactor.  The first reactor is preferably an ebullated bed type catalytic reactor and the second reactor is preferably a fixed bed type catalytic reactor which is operated at an inlet temperature 20-200°F lower than the first reactor effluent stream temperature.

Abstract: ABSTRACT OF THE DISCLOSURE           The present invention relates to powdered sulfonated thermoplastic polymers which function as viscosification agents when added to oil-based drilling muds which are the fluids used to maintain pressure, cool drill bits and lift cuttings from the holes in the drilling operation for oil and gas wells.  The powdered sulfonated thermoplastic polymer has 5 to 100 meq. of sulfonate groups per 100 grams of the sulfonated thermo-plastic polymer, wherein the sulfonated groups are neutralized with a metallic cation or an amine or ammonium counterion.   The powdered sulfonated thermo-plastic polymers have a particle size range of 0.25 µm to 2.5 µm and are prepared by spray drying an emulsion of the sulfonated thermoplastic polymer which has been prepared by a free radical copolymerization process.  A polar cosolvent can optionally be added to the mixture of oil drilling mud and sulfonated polymer, wherein the polar cosolvent increases the solubility of the sulfonated polymer in the oil drilling mud by decreasing the strong ionic interactions between the sulfonate groups of the sulfonated polymer.
