Abstract: Elastomer composites are produced by novel continuous flow methods and apparatus in which fluid streams of particulate filler and elastomer latex are fed to the mixing zone of a coagulum reactor to form a mixture in semi-confined flow continuously from the mixing zone through a coagulum zone to a discharge end of the reactor. The particulate filler fluid is fed under high pressure to the mixing zone, such as to form a jet stream to entrain elastomer latex fluid sufficiently energetically to substantially completely coagulate the elastomer with the particulate filler prior to the discharge end. Highly efficient and effective elastomer coagulation is achieved without the need for a coagulation step involving exposure to acid or salt solution or the like. Novel elastomer composites are produced. Such novel elastomer composites may be cured or uncured, and combine material properties, such as choice of filler, elastomer, level of filler loading, and macro-dispersion, not previously achieved.

Abstract: A composite motor housing is used with a motor of a window regulator. A magnet is inserted within the housing to assist the motor in spinning. A ferrous magnet housing lines the interior surface of the body portion of the motor housing to prevent the magnetic field produced by the magnet from escaping from the motor housing and affecting other components of the vehicle door. A bearing is molded into the top portion of the motor housing. In an alternative embodiment, the motor housing is formed of a ferrous matrix composite material, eliminating the need for the ferrous magnet housing. In another alternative embodiment, the bearing is integrated into the top portion of the motor housing, eliminating the need for a molded in bearing.

Abstract: Elastomer composite blends are produced by novel wet/dry mixing methods and apparatus. In the wet mixing step or stage, fluid streams of particulate filler and elastomer latex are fed to the mixing zone of a coagulum reactor to form a mixture in semi-confined flow continuously from the mixing zone through a coagulum zone to a discharge end of the reactor. The particulate filler fluid is fed under high pressure to the mixing zone, such as to form a jet stream to entrain elastomer latex fluid sufficiently energetically to substantially completely coagulate the elastomer with the particulate filler prior to the discharge end. Highly efficient and effective elastomer coagulation is achieved without the need for a coagulation step involving exposure to acid or salt solution or the like. Novel elastomer composites are produced.

Abstract: Integrated drilling and evaluation systems and methods for drilling, logging and testing wells are provided. The drilling and evaluation systems are basically comprised of a drill string, a drill bit carried on a lower end of the drill string for drilling a well bore, logging while drilling means included in the drill string for identifying subsurface zones or formations of interest, packer means carried on the drill string above the drill bit for sealing a zone or formation of interest below the packer means, and a fluid testing means included in the drill string for controlling the flow of well fluid from the zone or formation of interest into the drill string. The drilling and evaluation systems and methods for using the systems allow one or more subsurface zones or formations of interest in a well to be drilled, logged and tested without the necessity of removing the drill string from the well.

Abstract: Elastomeric compositions are produced by novel continuous flow methods and apparatus in which fluid streams of particulate filler and elastomer latex are fed to the mixing zone of a coagulum reactor to form a mixture flowing continuously from the mixing zone through a coagulum zone to a discharge end of the reactor. The particulate filler fluid is fed under high pressure to the mixing zone, such as to form a jet stream to entrain elastomer latex fluid sufficiently energetically to substantially completely coagulate the elastomer with the particulate filler prior to the discharge end. Semi-confined flow of the mixture in the coagulum zone is achieved preferably with progressively increasing cross-sectional dimension of the coagulum zone from the mixing zone to the discharge end. Highly efficient and effective elastomer coagulation can be achieved without the need for a coagulation step involving exposure to acid or salt solution or the like.

Abstract: A hydraulic set packer for use in a well bore as part of a testing apparatus. The packer comprises a housing defining a generally annular piston chamber therein. A cylindrical portion of an annular piston is slidably disposed in the piston chamber. The piston also has a shoe portion adjacent to a packer element on the housing. An inner mandrel is disposed in the housing, and the housing and inner mandrel define a passageway therein such that fluid pressure may be applied to the piston for moving it against the packer element such that the packer is set in sealing engagement with the well bore. The passageway extends the full length of the housing so that it may be in communication with another hydraulic packer positioned therebelow. One or more packers may be used in a downhole tool on a testing string for use in testing a well formation. The packer may also be used on a tubing string for testing a blowout preventer.

Abstract: A pair of design elements are suitable for display within the interior of a left and right shoe which make up a pair of children's shoes to aid the child in aligning the shoes for proper fitting onto the correct feet. The individual design elements are themselves complete and, further, are not indicators of proper alignment without their association with a picture story which may comprise a simple declarative sentence such that a mental step is required by the child in order to ascertain that the shoes are properly aligned. This picture story also requires the child to make a visual and directional alignment of the design elements in a left to right orientation which aids the child in gaining reading skills.

Abstract: A steel which contains up to 0.15% carbon, 0.5 to 1.5% manganese, 0.03 to 0.10% silicon, less than 0.2% molybdenum, up to 0.05 aluminum, 0.03 to 0.05% titanium and 0.002 to 0.008% boron is particularly suitable as a welding consumable, for example as an electrode for the submerged arc welding of high strength micro-alloyed structural steels. Especially when used with a basic flux, welds can be produced showing excellent notch toughness characteristics.
