    摘要: Improved methods of treating water and hydrocarbons producing subterranean formations to reduce the water permeabilities of the formations without substantially reducing the hydrocarbons permeabilities thereof are provided. The methods basically comprise introducing into the formation a chemical which does not resist water flow and attaches to adsorption sites on surfaces within the porosity of the formation but slowly washes off the sites as another fluid flows through the treated formation. Thereafter, a water flow resisting polymer is introduced into the formation so that it flows deeply into the porosity of the formation before the previously introduced chemical washes off and attaches to the adsorption sites as the chemical washes off.

    摘要: Disclosed is a method and apparatus for using far field scattered and diffracted light to determine whether a collection of topological features on a surface (e.g., a semiconductor wafer) conforms to an expected condition or quality. This determination is made by comparing the far field diffraction pattern of a surface under consideration with a corresponding diffraction pattern (a "baseline"). If the baseline diffraction pattern and far field diffraction pattern varies by more than a prescribed amount or in characteristic ways, it is inferred that the surface features are defective. The method may be implemented as a die-to-die comparison of far field diffraction patterns of two dies on a semiconductor wafer. The portion of the far field scattered and diffracted light sensitive to a relevant condition or quality can also be reimaged to obtain an improved signal-to-noise ratio.

    摘要: A molded suture retainer is provided for retaining and storing sutures. Both absorbable and nonabsorbable sutures fabricated from natural or synthetic materials can be advantageously retained and stored therein. The retainer is characterized by a wide spiraling oval passageway with minimal convolutions covered by a cover sheet. The length of the passageway is preferably proportional to 1/3 to 1/2 the overall length of the suture to be retained therein. Recesses are provided for receiving package stabilizing agents and/or needle parks. Sutures packaged in accordance with the invention exhibit fewer kinks and bends than prior packaged sutures.

    摘要: A suture display rack and procedure kit is provided which, upon folding, presents a plurality of stacked suture packages for seriatim review. The suture display rack is a substantially U-shaped structure with a floor portion and two opposing sidewall portions. A longitudinal fold line is provided in the floor portion parallel to the planes formed by the side walls such that, upon folding, the side wall portions may be brought into the same horizontal plane to form the base for the suture display rack. The suture packages may be loosely held in the rack or alternatively hinged to a side wall or contained in sheaths for ease of review and removal. The suture display rack may be securely adhered to a desired surface or may be set up in a portable manner.
