Abstract:
A method of improving the adhesion and durability of both new paint coatings, and older cracked or peeling paint coatings on an architectural surface is described. An aqueous wax emulsion (AWE) which, upon drying, forms an aqueous wax emulsion coating (AWEC), is adherent to an architectural surface as well as to new and older paint coatings. The AWEC is furthermore waterproof, and is hyper-permeable to water vapor, thereby preventing moisture-related bubbling and peeling of the new and older paint coatings.
Abstract:
A chock block holder for installation in a vehicle body includes a hollow, generally triangular body having a central axis and having first and second ends, the first end being closed, and the second end being open, and a peripheral flange on the first end, the peripheral flange lying in a plane not perpendicular to the central axis. A method of storing a chock block in a vehicle body having a vertical side wall, includes the steps of placing a chock block holder in the form of a hollow, generally triangular body having a central axis, and first and second ends, the first end being closed, and the second end being open and having a peripheral flange on the first end, the peripheral flange lying in a plane not perpendicular to the central axis, in an opening in the side wall so that the flange is in contact with the side wall and the first end is downward from the second end; and fastening the flange to the side wall.
Abstract:
A method of increasing the HDL concentration and the HDL/LDL concentration ratio in human serum by providing a balance between a sufficient and required proportion of cholesterol-free saturated fatty acids in the daily dietary fat of the human and a sufficient and required, but not excessive, proportion of polyunsaturated fatty acids comprising linoleic acid in dietary fat, while the remaining proportion of fatty acids and energy from the dietary fat is provided by monounsaturated fatty acids comprising oleic acid. The saturated fatty acids must constitute between 20% and 40% by weight of the daily dietary fat based upon dietary fat accounting for 30% of the total dietary energy consumption, and linoleic acid must constitute between 15% and 40% by weight of dietary fat. In this way, the required proportional intake of polyunsaturated fatty acids enhances the formation of HDL from VLDL and/or decreases the clearance of HDL, while an excessive proportional intake of polyunsaturated fatty acids and monounsaturated fatty acids is avoided to assure a sufficient dietary availability of saturated fatty acids which are required for sufficient VLDL synthesis and HDL production.

Abstract:
A method for forming an agarose electrophoretic gel by addition of gamma-irradiated clarified galactomannan (.gamma.CGM) to optically clarify the gel and improve the electrophoretic fractionation and resolution of oligonucleotides differing in molecular weight. The gel includes agarose, an electrophoretic buffer for nucleic acids, and a CGM vegetable gum subjected to between 0.1 and 4.0 megarads of ionizing gamma radiation.
Abstract:
A microcentrifuge tube or other thermoplastic sample container having a round opening and a frictionally seated sealing lid, the lid having a size and shape to cover the perimeter of the tube opening and maintain the inside of the tube free of any contaminant. The lid viewed on an upright closed container has a downwardly extending annular portion shaped to sealing fit inside the opening, the lid further having an integral upwardly projecting lid extension configured and arranged on top of the lid to facilitate aseptic opening, grasping and identification-labeling of the container. The location, angle and size of the lid extension allow mechanical pressure to be used on top of the lid, rather than beneath the lid, to open the container. The improved apparatus and method for opening the container functions to prevent sample contamination which could otherwise occur when a fingernail or other container opening instrument is inserted beneath, and contacts some portion(s) of the underside of the lid. The location, size, and surface finish of the lid extension also allow grasping of the microcentrifuge tube after placement in a centrifuge rotor or storage rack, as well as labeling the tube for sample identification and tracking purposes.
Abstract:
Marking tape adapted for use in autography, comprising: a substrate having an upper surface, a phosphorescent coating applied to the upper surface, the coating including phosphor powder grains, the grains phosphorescing with light at a wavelength between 400 and 600 nm upon exposure to UV or visible light, the phosphorescing occurring for a period of at least 5 minutes after the exposure, the concentration of the grains being sufficient to emit sufficient photons and thereby cause X-ray film having a sensitivity of 2000 EI to darken to an optical density of between 0.2 and 3.0.
Abstract:
A pipetter barrel extension tube, attachable at its proximal end to any one of a variety of pipetter barrels and at its distal end to standard disposable pipetter tips. The pipetter barrel extension tube serves to extend the length of the barrels and provide sterile access to deep containers while substantially isolating the permanent barrel of the micropipet from damage caused by chemical and radiochemical contamination. One novel design feature of the extension tube is an air channel designed to minimize dead air volume in the extension tube. A removable conical insert plug serves to reduce the air channel volume. Removal of the plug facilitites cleaning and reuse of the extension tube. The device also includes a distal end segment which, when intact, serves as a space-filler to reduce dead air volume in disposable tips for pipetting small volumes. When the segment is removed, the extension tube still attaches to the same disposable tips but allows larger volumes of liquid into these tips as required for larger capacity pipetting devices.
Abstract:
A solution which increases the efficiency of radon extraction from either dry or moist charcoal samples is disclosed. The addition of low molecular weight organic solvents such as methanol or ethanol to liquid scintillation counting solution increases radon extraction from 20-500% over known counting solutions. The increased efficiency appears to occur from increased penetration of the charcoal by the low molecular weight solvent which dissolves the radon gas and the subsequent diffusion of the low molecular weight solvent out of the charcoal and into the liquid scintillation counting solution.
Abstract:
A radiation shield suitable for preventing radiation and radioisotopes from reaching or contacting a person using a vessel containing a radioactive solution. The shield includes a radiopaque container having a top and a bottom opening, and a means for supporting the vessel within the container. The container reduces emission of radiation through the sides of the vessel.
