Abstract:
A surgical hip wrap comprising an elongated fabric strip that is wrapped around a hip of a user to cover and/or protect it. The fabric strip is held in place by securing one end region around the waist of the user and by securing the opposite end region around the adjacent upper thigh region of the user. These end regions are secured to the fabric strips such as by a hook and loop closure system or adhesives or the like. The non-linear opposite end regions are offset one from the other, but they extend along generally parallel lines.
Abstract:
The invention provides an apparatus for removing at least one bead from a tire. The apparatus includes a conveyor for tires and a sensor which centers the tire about a debeading device and a cutting device. The conveyor then moves the cut tire to a second position wherein the bead is pulled from the tire. A microprocessor is used to position the tires and for resetting the devices for treating additional tires.
Abstract:
There is provided a process for reclaiming elastomeric waste material, particularly rubber, which includes the steps impregnating the elastomeric waste material with an essential oil and then heat treating the impregnated material under reduced pressure with microwave radiation.
Abstract:
A method is provided for in situ decontamination of contaminated subsurface area by injection of steam into injection wells and withdrawing liquids and vapors from extraction wells under subatmospheric pressure whereby steam is passed through the contaminated area in an essentially horizontal direction. After a substantial portion of the contamination has been removed in this manner, the injection of steam is ceased, but the extraction at subatmospheric pressure is continued, to volatilize and remove the residual water and contaminants trapped in the pores of the soil. The steam injection may be periodically resumed to reheat the area and to replenish the water in the pores.
Abstract:
In a rinser/dryer for carriers of semiconductor wafers, a rotatable frame containing the carrier is directly mounted to, and cantilevered from the drive motor. A container encloses the rotatable frame and carrier. A gas pressurized labyrinth seal separates the inside of the container from the drive motor to prevent contamination. A raised portion in the labyrinth seal, with gas inlets on each side of the raised portion, forms a pressure barrier inhibiting the passage of moisture and contaminates across the barrier.
Abstract:
A powder composition which reacts in water to form in situ peroxycarboxylic acids at an anti-microbially effective concentration. Importantly, its utility is both for topical anti-microbial application and for effective low temperature disinfection/sterilization of instruments. It comprises the combination of a perborate, one or more novel acyl and/or aroyl donors, a buffering system which allows the pH to arise to about 9 for rapid formation of the peroxycarboxylic acids and then drop to about 7.5 for sustained stability and microbial kill. It preferably includes a surfactant facilitating antimicrobial efficacy, as well as other minors.
Abstract:
A non-foaming periodontic composition in a gel form or mouth wash for treating gum diseases or used in bleaching teeth which are alcohol free. The composition is a mixture of an isoalkyl amine oxide and an antimicrobial betaine compound. The composition is useful for treating gum disease and whitening teeth.
