Abstract: The installation and use of abrasion and corrosion resistant polyolefin and polyolefin blend liners in the production or injection string of a well is shown. The lining is employed for the principal purpose of reducing wear or corrosion on the tubing string or wear on the associated production equipment. In a preferred embodiment of the invention, the polymer liner is characterized by polypropylene material, which is abrasion resistant and which has a coefficient of friction that is lower that the coefficient of friction of metal tubing. Also, disclosed herein are tubular goods and tubular good liners which decrease or eliminate friction and mechanical wear and decrease or eliminate chemical corrosion to the walls of the tubular good. The liners may include a diffusion barrier, an adhesive, and a friction and wear resistant layer.

Abstract: A method of welding an axle housing surface to a blank surface includes generated heat in one of the two components. Heat is generated from at least one of these surfaces at their interface sufficient to weld them together. The surfaces are then applied together.

Abstract: The present invention provides a method for using Aloe vera as a biological vehicle for the delivery of drugs. In one embodiment Aloe vera is used as a biological vehicle to deliver the estrogen, .beta.-estradiol and the androgen, testosterone propionate. The present invention also provides a method of treating symptoms and diseases mediated by hormonal deficiencies or amenable to treatment by hormones using Aloe vera as a biological vehicle.

Abstract: The instant invention provides a method for producing RNA enzymatically in a semi-batch or continuous-flow bioreactor using a DNA template immobilized to a solid support through a linkage having a single-stranded overhang extending from a noncoding strand. The coding strand remains dissociable from the immobilized noncoding strand. The immobilized RNA template is reused in at least sixteen rounds of transcription reaction. The coding strand can be replaced with a fresh DNA strand encoding the same or a different RNA.

Abstract: The present invention describes a composition derived from the Aloe plant which when used as an adjuvant for the healing of wounds exhibits increased anti-inflammatory and wound healing activity. The composition, an Aloe vera mucilage at approximately a 1:1 ratio, preferably with Aloe pulp fibers, increased open wound healing activity and increased wound tensile strength by 131% over controls.

Abstract: Reaction products of hydrocarbylcarboxylic anhydrides and aminoalkanols can provide effective antiwear, antirust, and corrosion-inhibiting properties in lubricant and fuel applications.

Abstract: The invention relates to zinc and phosphorus free additives for lubricating compositions which are produced by a free radical reaction between a dimercaptothiadiazole and monomer oligomer or homologue of acrylates or methacrylate, which in minor amounts impart antiwear/extreme pressure and antioxidation properties to the lubricant.

Abstract: A fast-acting and portable diagnostic kit for detecting diamines in biological fluids is in the form of a diamine oxidase and a chromogenic system to detect the presence of hydrogen peroxide resulting from oxidation of such diamines. The kit may especially be used to detect cadaverine or putrescine or a mixture thereof, for example in a vaginal secretion, in order to detect Gardnerella-related bacterial vaginosis.

Abstract: Reaction products of Dimercaptothiadiazole-derived alcohols and alkenyl succinic anhydrides and their subsequent amine reaction products have been found to be effective antiwear/antioxidant multifunctional additives for lubricants.

Abstract: Disclosed herein is the reaction product of 5-amino-2-mercapto-1,3,4-thiadiazole with hydrocarbyl epoxides. The resulting reaction product finds use as an additive in lubricating oil compositions.

Abstract: Spaced elongated ribs each having a tapered end and a concave end are assembled together by means of elongated, spaced members inserted through respective spaced openings in each rib. The tapered ends of the ribs are attached to a common sheet of material which may be inserted underneath roofing shingles to position the entire assembly over a gutter to provide assistance to propel leaves, pine straw and other debris to the edge of the gutter but at the same time preventing the debris from entering the gutter while allowing the water to drain into the gutter. A continuous front member may be provided with clips for attachment to the edge of the gutter or may be omitted.

Abstract: Effective demulsifier additives prepared by the reaction of polyalkylenediamines with such carboxylic acids as naphthoic and abietic provide good resistance to water.

Abstract: Zinc/phosphorus-free antiwear agents and antioxidants are provided by reaction products of 2,5-dimercapto-1,3,4-thiadiazole with mercaptans and thionyl chloride.

Abstract: Water soluble lubricant compositions comprising alkanolamine and organic acid are improved by employing as the organic acid a partial acid amide of a dicarboxylic acid, such as mono-PRIMENE 81 R amide of succinic acid, mono-di-2-ethylhexylamide of maleic acid, mono-di-2-ethylhexylamide of methyltetrahydrophthalic acid and mono-di-2-ethylhexylamide of methylhexahydrophthalic acid as the organic acid.
