Abstract: A siphon apparatus having a uniquely designed base for initiating fluid transfer from any fluid container having an opening which is large enough to accommodate a single tube to a desired site in a reasonably short transfer time without the likelihood of spillage or unintentional bodily contact with the fluid being transferred. The siphon apparatus includes the base having two distinct openings for inserting a pressure inducing device and a fluid transfer tube. The base also includes an internal channel for connecting the pressure tube opening to the fluid transfer tube opening thereby allowing air introduced into the pressure inducing tube to enter the sealed fluid container through the opening for the fluid transfer tube. The apparatus may be stored in a compact carrying case or may be hung on a wall by forming the pressure inducing tube and the fluid transfer tube into a single tubular loop.

Abstract: A method to prevent fiber distortion in textile materials employed in a modified weaving process. In a first embodiment, a tacifier in powder form is applied to the yarn and melted while on the fabric. Cool air is then supplied after the tacifier has melted to expedite the solidification of the tacifier.

Abstract: The present invention pertains to a process for preparing ceramic shells as casting molds, wherein a) a pattern of a part to be cast, which pattern can be melted or dissolved out, is prepared, b) the pattern is dipped into a dip-coating composition of a slurry of a refractory material and a binder in order to form a wet coating on the pattern, c) a coarse refractory powder is sprinkled onto the coating, d) the coating is dried, and e) steps b), c) and d) are repeated until the mold shell has reached the desired thickness. A ceramic protective material is added to the dip-coating composition and/or to the coarse refractory powder. Carbon is introduced into the ceramic protective material during the preparation in the molten state. The carbon is able to chemically bind oxygen at the time of the cooling of the casting essentially at mold temperatures above the firing temperature of the casting mold and is thus able to prevent skin decarburization and surface defects in carbon-containing steels.

Abstract: A gravel-packing apparatus and method is disclosed which involves a movable sleeve over a screen. The screen is fixed to a packer downhole while the sleeve is operated from the surface. As the sleeve is lifted to expose more of the screen, the granular material deposits along the outside of the screen and through the exposed perforations, starting from the packer and working its way up. The annulus is sealed by multiple cup seals or other suitable seals for the environment so that the slurry pressure applied from the surface is directed to deposition of the granular material adjacent the exposed perforations. As more granular material is deposited, the crew at the surface may further pull the sleeve up or the developed pressure downhole itself can force the sleeve further up, exposing additional perforations and continuing the deposition process of the granular material.

Abstract: Enhanced gel properties (e.g., faster gel time, higher attainable gel strengths) are achieved by reducing the pH and/or increasing the salt of a monovalent and/or divalent cation concentration of an aqueous reaction medium in which a polymer is reacted with an organic crosslinking agent. In addition, the gelation time of an aqueous composition comprising a polymer and an organic crosslinking agent is reduced by heating the composition above about 48.9.degree. C. (120.degree. F.) prior to injecting the composition into a subterranean formation. Alternatively, the gelation time of the aqueous composition is increased by incorporating a pH increasing agent into the composition.

Abstract: Fractures are initiated or extended into fluid producing earth formations from a well by providing a reservoir of high pressure gas at the earth's surface together with a flow control valve or a frangible closure, such as a shear disk, interposed in a conduit connecting the reservoir to the well.
