摘要： The invention relates to a method of making a thixotropic gel for partitioning separated phases of a fluid sample, the phases having differing densities and the gel having a density intermediate those of the phases, wherein a silicone fluid, a filler material and a network former are reacted to form the gel, characterised in that the silicone fluid has a first viscosity and comprises a single stock fluid or a blend comprising at least two blend stock fluids, each said stock fluid in the blend having a viscosity within about ±15% of said first viscosity, and said gel-forming reaction is carried out at or below about 120°C. The gel produced is primarily intended for partitioning the serum and clot portions of a blood sample. The invention includes a fluid sample collecting and separating device incorporating the gels of the invention.

摘要： This disclosure is concerned with a process of and apparatus for producing relatively low energy electron beams through pulsed cold-cathode beam generation in a mode of operation involving an important intermediate region of a substantially linear depth-dose profile characteristic that reduces the sensitivity to possible voltage variations, and with improved triggering structures that significantly improve reliability and minimize erractic pulse genera- _ tion and missing pulses, thus particularly adapting the process and apparatus for such stringent applications as production-line steritization of surfaces, materials or workpieces passed by the apparatus.

摘要： (D A novel irradiation process and products made thereby are disclosed. Biological media such as blood, blood fractions, genetically engineered protein products and vaccine preparations are treated by said process, photolyzing nucleic acids in preference to proteins in said media. E.g., DNA- or RNA-containing pathogens are inactivated while leaving the proteins substantially intact or functional. In general, the process comprises irradiating the medium with pulsed light of wavelength and flux selected so that (1) the nucleic acids in their ground state absorb radiation and thereby rise to an excited state or states, (2) the nucleic acids in their excited states absorb radiation and thereby rise to higher energy states and undergo photolysis, and (3) the proteins in their ground or their excited states do not absorb sufficient radiation to undergo substantial photolysis. It is surprising and unexpected that nucleic acids in their excited states undergo efficient photolysis whereas proteins under the same conditions in the same medium are kept substantially intact.

摘要： A composition sufficiently irradiated to achieve sterilization comprising an aromatic carbonate polymer in admixture with an anti-yellowing upon exposure to sterilization irradiation effective amount of a boron compound having part of its structure at least one
or
group wherein R is selected from alkyl of one to twenty-four carbon atoms, inclusive, alkenyl of two to twenty-four carbon atoms, inclusive, cycloalkyl of four to fourteen carbon atoms, inclusive, aryl of six to fourteen carbon atoms, inclusive; and substituted phenyl wherein there are one to three substituents which are the same or different and are alkyl of one to six carbon atoms, inclusive, alkoxy of one to six carbon atoms, inclusive, and halo; and
R' is selected from the same group as R with a further hydrogen atom replaced by a bond to the second oxygen.-

摘要： The normal tendency of aromatic polycarbonate homopolymers and copolymers, alone or in blends with second resins, to undergo yellowing when exposed to ionizing radiation, as in certain sterilizing procedures, is diminished or eliminated by the inclusion of compounds having the effect of increasing the radiation resistance of the polymers. These compounds are, in general, characterized by a strong oxidizing action and/or reaction at high reaction rate with active species such as H radicals, OH radicals and/or hydrated electrons formed by ionizing radiation.

摘要： A nonwoven fabric repellent to body fluids and having reduced odor on sterilization by irradiation or steam is made by bonding nonwoven fibers with a latex, forming said nonwoven fabric, and sterilizing said fabric, said latex is prepared by polymerizing, in the presence of 0.1 to 2 weight parts of a free radical initiator and a sufficient amount of a nonionic or anionic emulsifier, 65 to 85 weight parts of a soft hydrophobic monomer having Tg of -80°C to -20°C, 10 to 30 weight parts of a hard hydrophobic monomer having Tg of +40°C to +120°C, 0.1 to 5 weight parts of an unsaturated carboxylic acid containing 3 to 6 carbon atoms, and 0.1 to 5 weight parts of N-alkylol acrylamide or methacrylamide containing 1 to 10 carbon atoms, said latex has post-added and admixed therein 0.01 to 5 weight parts of an odor inhibition agent selected from amine-type antioxidants and hindered phenols that function to reduce odor of said fabric on sterilization thereof.
