摘要： Non-conductive or poorly conductive resinous materials such as organic polymers are rendered highly conductive, e.g., volume resistivities as low as 10 3 ohm-cm, by including therein a finely divided, copper metal-containing solid, a reactive metal such as zinc, silver or the like and a halide source such as a vinylidene chloride copolymer and reacting the reactive metal with the halide source to form the conductive material. Such compositions can be fabricated into thin layers which are useful as electrodes in capacitors and into other articles wherein electroconductivity is required.

摘要： An egg carton structure, particularly designed to package extra large or jumbo grade size eggs and the like, having a bottom section with a plurality of downwardly disposed deep receiving pockets or cells and an interconnected closable cover and locking means. The walls of adjacent cells extend upwardly to form resilient dividers or separators between the cells to prevent contact of eggs reposing in adjacent cells. Variable thicknesses of cell and divider walls, in conjunction with a combination of other unique elements, results in a structure which can be easily thermoformed into a serviceable carton and does not require extensive lateral or transverse ribs, walls or other means to provide lateral support between cells or general stiffness reinforcement of the egg carton as previously considered necessary.

摘要： An improved process for conversion of substrates to products by use of enzyme/cofactor combinations in conjunction with semipermeable membranes is disclosed. Loss of cofactor through such membranes is largely prevented simply by employing an excess of the enzyme over the stoichiometric amount required to complex essentially all of the cofactor.

摘要： Method of quantitative analysis of a single ion species paired with at least one species of counter valent ion in an aqueous or highly polar sample solution, the solution containing substantially no other ions of the same valence as said single ion species, save for ions capable of forming a relatively undissociated ion pair with hydrogen ions or hydroxide ions, in which the sample solution is added to an ion exchange resin bed, the resin being an ion exchange resin capable of exchanging ions of the same valence as the at least one species of counter valent ion and the ion exchange resin being in an ion form easily eluted by other ions of the same valence, eluting the single ion species from the ion exchange resin bed and quantitatively detecting the single ion species with a conductivity cell and associated readout means. The apparatus is an ion exchange column charged with an ion exchange resin in an ion form easily elutable by the counter valent ions accompanying a single ion species to be determined, a conductivity cell and associated read-out means, means for bringing sample solution and eluant water to the ion exchange column and liquid conduit means for conducting effluent from the ion exchange column to the conductivity cell.

摘要： Dentifrice compositions fortified with a trace to 15 percent of a substantially water-insoluble stannous chelate of a synthetic amino carboxylic acid wherein the chelate moieties have an Sn:N ratio of 1:1. Their use induces reaction of stannous tin with dental enamel to form a complex basic stannous phosphate, and thereby reduces the solubility of the enamel.

摘要： Aqueous warp sizing compositions and the sized yarns obtained by applying the new sizing composition to textile yarn, removing excess composition from the yarn, drying the resulting wet-sized yarn and separating the individual yarns (ends) from one another before or after drying. The novel aqueous sizing composition is a blend of a lubricant, a surfactant, a redispersible latex composition and various optional ingredients. The redispersible latex component comprises a blend of (a) a six-membered carbocyclic compound having two carboxyl substituents and which is soluble in aqueous alkaline media such as the disodium salt of 1,2,3,6-tetrahydrophthalic acid and (b) an aqueous colloidal dispersion of a film-forming carboxyl-containing polymer such as a copolymer of styrene, butadiene and acrylic acid.
