Abstract: The present invention provides a process to create without mechanical agitation a zone of low shear, low turbulence flow pattern within a continuous phase liquid contained in a vessel by a continuous or periodic injection of an inert, immiscible, low density fluid, preferably gas, into the liquid to form such a flow pattern, recovering the fluid above the free surface of the liquid and, preferably, reinjecting it into the liquid. The invention is particularly useful if the continuous liquid contains a dispersed phase which should be distributed within the continuous liquid without excessive particle agglomeration or breakups in order to largely preserve the initial particle size distribution, or if the initial particle size distribution needs to be modified by controlled breakups of the largest particles, particularly during the subsequent batch processing.

Abstract: “Cast” films having excellent puncture resistance and tear strength are manufactured from “pseudohomogeneous” linear low-density polyethylene resin. The preferred pseudohomogeneous resins used in the present invention are prepared with an advanced Ziegler Natta catalyst (having a magnesium component and a titanium component), preferably in medium pressure solution polymerization process. The films of this invention are especially suitable for “pallet wrapping” and for wrapping goods of unusual or uneven shapes and sizes.

Abstract: An ethylene styrene copolymer having isolated styrene monomer units separated by 5 or 6 methylene groups as determined by 13C-NMR may be polymerized in the presence of an activator and a transition metal catalyst containing a phosphinimine ligand.

Abstract: A phosphinimine catalyst for olefin polymerization is supported on a directly fluorided metal oxide with an aluminoxane. This catalyst is highly active for olefin polymerization in comparison to prior art catalysts which use non-fluorided metal oxide supports. The directly fluorided metal oxide may be conveniently prepared by contacting the precursor metal oxide with a simple alkali metal salt (such as NaF) in an aqueous slurry.

Abstract: A friction stir welding tool includes a friction stir welding head having a probe and spindle rotatably mounted at a first end. A support supports the stir welding head between the first end and a second end for movement about a pitch axis. A pitch actuator includes an elongated arm coupled to the stir welding head at a point longitudinally spaced from pitch axis to overcome the relatively large forces exerted at the probe. A turntable supports the stir welding head for movement about a yaw axis. A yaw actuator includes an elongated arm coupled to the turntable laterally spaced from the yaw axis, to overcome the relatively large forces exerted at the probe. A controller maintains an angle of attack of the probe with respect to direction of travel of the probe along the work piece.

Abstract: A method is presented for controlling a process to be applied to a patterned structure in a production run. Reference data is provided being representative of diffraction signatures corresponding to a group of different fields in a structure similar to the patterned structure in the production line, and of a control window for the process parameters corresponding to a signature representative of desired process results. The group of different fields is characterized by different process parameters used in the manufacture of these fields. The method utilizes an expert system trained to be responsive to input data representative of a diffraction signature to provide output data representative of corresponding effective parameters of the process. Optical measurements are applied to different sites on the patterned structure in the production line to obtain diffraction signatures of thereof and generate corresponding measured data.

Abstract: Non-Newtonian fluids, such as partially polymerized monomers or solutions of polymer in monomer may be pressure atomized below the surface of an immiscible continuous liquid phase to produce a dispersed phase having a uniform particle size distribution. A dual or customized size distribution can be obtained by imposing a controlled pressure pulsation on a flowing fluid upstream the atomizer inlet. Such dispersion may be further polymerized to produce a uniform or customized bead size product.

Abstract: New sensors and different embodiments of multi-channel integrated circuit are provided. The new high energy and spatial resolution sensors use both solid state and scintillator detectors. Each channel of the readout chip employs low noise charge sensitive preamplifier(s) at its input followed by other circuitry. The different embodiments of the sensors and the integrated circuit are designed to produce high energy and/or spatial resolution two-dimensional and three-dimensional imaging for widely different applications. Some of these applications may require fast data acquisition, some others may need ultra high energy resolution, and a separate portion may require very high contrast. The embodiments described herein addresses all these issues and also other issues that may be useful in two and three dimensional medical and industrial imaging.
