Abstract: (59-2) ABSTRACT         A hydraulic tensioning arrangement for and endless drive belt for a vehicle accessories drive system.  The vehicle alter-nator is pivotally mounted on the engine and is driven by a pulley which is drivingly engaged with the drive belt.  A hydrau-lically actuated piston is mounted in a generally fixed position on the engine closely adjacent to the alternator and is opera-tively connected to the alternator for pivotally moving it to a belt tensioning position.  Hydraulic fluid is supplied to the piston cylinder from the vehicle's power steering fluid supply. A ratchet bar is mounted on the piston cylinder and is slidably engaged in a guide bracket mounted on the alternator.  A spring-biased pawl is mounted on the guide bracket and is engageable with a series of teeth formed on the extended end of the ratchet bar.  The pawl-teeth engagement prevents movement of the alter-nator away from the belt tensioning position during a decrease in hydraulic fluid or pressure in the piston cylinder to mechanically maintain a constant predetermined belt tensioning force on the belt at all times without the use of springs.

Abstract: ABSTRACT OF THE DISCLOSURE In the melt-spinning of filaments molten polymer is extruded down-wardly through circularly arranged holes of a spinneret to form a circular group of filaments.  Quench gas and finish liquid are conducted downwardly through the spinneret in alignment with a longitudinal axis defined by the filament group and are directed outwardly through the filament group.  The filaments exhibit vibration during travel from the spinneret to the lower guide.  The filaments are passed through and against a circular guide sur-face disposed around the filament group below the finish spray and above the lower guide.  As a result, the filaments are deflected inwardly, in mutually spaced relationship, toward the longitudinal axis, whereby the amplitude of vibration of the filaments is reduced.  The filaments are passed between walls extending upwardly from the guide surface and surrounding the filament group.  Finish liquid is sprayed against the walls so that a finish environ-ment is confined between the walls.  The guide may comprise relatively mov-able members which close around the filament group to define a continuous guide surface.

Abstract: -.20 -SELF-CLEANING SCREEN ASSEMBLY FOR RADIATOR AIR INLETS          ABSTRACT  OF THE DISCLOSURE            A casing is secured to the front of the radiator air intake of a tractor or the like and a cylindrical screen assembly is journalled for free rotation to the casing.  A fan blade assembly is secured to the inner end of the cy-lindrical screen assembly so that air drawn through the radiator by the engine cooling fan, passes through the fan assembly of the screen assembly and rotates the screen assembly.  A blanking plate is supported within the screen assembly which blanks off part of the screen as it passes thereby, so that no air passes into the screen assembly in this area.  This releases chaff and the like normally held on the surface of the screen by suction.  The fan blade assembly is provided with small additional blades on the periphery thereof, positioned to generate a slight posi-tive pressure in the annular area between the periphery of the fan blade assembly and the casing as the screen assem-bly rotates, in order to provide an air seal and to pre-vent any chaff and the like from being drawn into the radiator around this area.

Abstract: ABSTRACT OF THE DISCLOSURE A turbine has a disc pack rotor with a central aperture-free or solid disc that divides the pack into two equal portions.  The annular discs of each portion have aligned, central and unobstructed exhaust openings and the outer end disc of each portion is a support member having a webbed hub that is attached to a respective drive shaft journalled in the turbine cas-ing.  A stationary circular nozzle assembly closely surrounds the outer cir-cumference of the disc pack to form one or more convergent-divergent nozzles that guide motivating fluid from an outer casing plenum into spaces between neighboring discs.  The discs are separated from one another and intercon-nected by fences that guide the motivating fluid to the exhaust openings in each pack portion.  Thus, fluid enters the pack circumference and is split into two parts by the center disc to exhaust in relatively opposite direc-tions.  The shaft for each pack portion preferably terminates at the outer support disc to form a two-direction "shaftless" rotor.

Granted: 1985-02-05
Abstract: ABSTRACT A device for fabricating multi-layer tubing has a reservoir for tubing solution and discharges such solution from an opening in the reservoir bottom. The reservoir is suspended so as to remain level. Extending through the opening is a vertical rod of smaller diameter but itself suspended by a flexible wire so as to remain vertical. Material in the reservoir extrudes as an annulus even in cross-section by passing between the edge of the reservoir opening and the rod. Such extruded material hardens into one layer of the tubing. There is a repetition with a larger reservoir opening and so depositing a larger tube that is dried on and over the first tube. This is repeated as often as desired to get a finished tube of the proper inside and outside diameter. The method is following in succession the steps described above.

Abstract: ABSTRACT          Charged-particles in the 45 - 15 MeV energy range incident upon isotopically enriched xenon-124 gas in a gas-target assembly cause nuclear reaction which yield radioactive xenon-123.  The venon-123, decaying either in the target assem-bly or in a decay vessel removed from the target assembly; yields iodine-123 with very low levels of radioactive contamin-ants.                         LITERATURE SURVEY          There are many publications concerned with the production of iodine 123.  Three reviews are given by:  Sodd et al, Isotop.          Radiat. Technol. 9 (1971/1972) 154-159, "Evaluation of Nuclear Reactions That Produce I-123 in the Cyclotron"; Weinreich, Proceedings of the Panel Discussion, "Iodine-123 in Western Europe. Production, Application, Distribution", Julich, Feb. 13, 1976, "Critical Comparison of Production Methods for Iodine-123", pages 49-69; Van den Bosch, Thesis, Technische Hogeschool Eindhoven, The Netherlands, Oct. 1979. "Production of I-123, Br-77, and Y-87 with the Eindhoven AVF Cyclotron".          The applicability of iodine-123 to diagnostic studies and its advantages over other radioiodines are outlined in these reviews and by Myers et al, Radiopharmaceuticals and Labelled Compounds, Vol. 1, Vienna, IAEA/SM-171/34, 1973, "Radioiodine-123 for Applications in Diagnosis".     Iodine-123 production routes may be divided into two general categories.  The first concerns nuclear reaction pathways which form iodine-123 directly, such as the reaction 124Te (p, 2n)123I.
