摘要:
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.

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.
摘要:
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.
摘要:
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.
摘要:
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.
摘要:
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.
摘要:
Water soluble lubricant compositions comprising alkanolamine and organic acid are improved by employing a monocycloalkyl-1,2,3,6-cis tetrahydrophthalate or hexahydrophthalate; or a monoaralkyl-1,2,3,6-cis tetrahydrophthalate or hexahydrophthalate as the organic acid.
摘要:
An emulsifiable concentrate for use in water-in-oil fire-resistant hydraulic fluids, comprises lubricant and a polyalkenylsuccinic acid or anhydride or a salt thereof.
摘要:
An emulsifiable concentrate for use in metal processing, especially in can forming, comprises an ester prepared from a polyalkenylsuccinic acid or anhydride, and a hydroxyl-containing amine. It is critical to the invention with respect to can forming that the acid or anhydride contain, in addition to its basic carbon length, a chain derived from an olefin having from 16 to 28 carbon atoms.
