Abstract: The disclosed method for forming an epoxy adhesive-bonded joint between a plurality of substrates is particularly well suited to an assembly line operation. The method involves forming an intimate mixture of the two components of a two-part adhesive system under conditions such that substantial curing will not occur until heat and/or pressure are applied. The application of heat and/or pressure for a short period of time initiates the curing reaction which will continue to completion under substantially normal ambient conditions. The initial bond strength is sufficient to hold mated substrates together with the bond strength increasing even when the curing process is completed under normal ambient conditions. For example, substrates can be coated with an intimate mixture of a two-part system suitable for use in this invention, stored for a period of time, mated on an assembly line under cure initiation conditions, and allowed to cure at normal room temperature and atmospheric pressure.

Abstract: An expanded material or conglomerate exhibiting outstanding fire-retardant properties and having an elevated specific weight contains 20 to 80% by weight of a binder constituted by a phenol-formaldehyde resin, 20 to 80% by weight of a gypsum obtained as a by-product in the preparation of phosphoric acid, and possibly inert filler materials which may be constituted by inorganic or organic substances.

Abstract: Corn grain yield can be increased without affecting grain quality by alteration of early plant growth. One particularly preferred technique of early plant growth alteration involves reducing the effective leaf area of a short-season hybrid growing in a full-season maturity zone. With optimization of early plant growth alteration of an appropriate hybrid in an appropriate maturity zone, corn grain yield increases in excess of 30% and even in excess of 75% can be otained.

Abstract: The disclosed method and apparatus for producing heat make use of a fuel/oxygen/water mixture in a reaction zone to provide unusually high temperature effluent gases.

Abstract: A six-carbon uronate (e.g. galacturonate or glucuronate) moiety is capable of complexing up to about 3 gram atoms of iron to provide a hematinic compound with high iron content, high bioavailability of iron (up to about 100% of FeSO.sub.4), reduced side effects (e.g. little or no metallic taste), and excellent compatibility with foodstuffs, pharmaceutical extenders, etc.

Abstract: The disclosed corrosion-inhibiting elastomers are typically made by milling the corrosion inhibitor into a solid rubber matrix. Preferred corrosion inhibitors include the aromatic carboxylates of primary, secondary or tertiary amines. Chromates and 2-ethylhexanoates can also be used. Organic ammonium nitrites are effective against some types of corrosion, but should be used with relatively inert elastomers. There appears to be synergistic cooperation between the elastomeric molecular structure and the corrosion inhibitor resulting in unusually effective protection of ferrous and/or nonferrous metals adjacent to rubber parts made from the corrosion-inhibiting elastomer.

Abstract: The disclosed process for making a high % solids, one-part, curable, essentially flowable or pumpable, high equivalent weight polyurethane (i.e., polyol-polyisocyanate adduct) prepolymer composition involves de-watering the polyol component of the reaction mixture with an alkaline earth metal oxide, preferably calcium oxide; adding the minimum acceptable level of catalyst for the NCO/polyol reaction; exothermically reacting a partially hindered aliphatic polyisocyanate such as isophorone diisocyanate (IPDI) and a partially hindered aromatic polyisocyanate such as 2,4-tolylene diisocyanate seriatim, so that at least about one-fourth of the IPDI reacts before the 2,4-TDI is added; and then adding more catalyst for the curing (e.g. moisture cure) reaction.

Abstract: A powdered, storage stable, effervescent formulation readily dispersible in water and containing a watersoluble chlorinated cyanurate, such as sodium dichloroisocyanurate, is mixed with water to provide a stable, slightly acid to neutral, non-irritating aqueous liquid having about 3,000 to 7,000 ppm titratable chlorine which is used as a teat dip for hygienic control of bovine mastitis.

Abstract: The disclosed organic ammonium phosphate salt concentrates can be diluted with water in the weight ratio of from 1:5 to 1:250 (concentrate:water) and used in bath, spray, or steam phosphatizing (sometimes called "phosphating"). These concentrates and the resulting diluted solution are reasonably pH-stable in the pH range of 3.0 to 5.5. Preferably, the concentrates contain a buffer, various surfactants, and, particularly for low temperature use (e.g. 20.degree.-55.degree. C.) an accelerator system. The concentrates are well suited to automatic dispensing of a phosphatizing spray or make-up solution (for a bath); they are efficient at low temperatures; and they have good storage stability.

Abstract: A ceramic dielectric composition is provided including 30 to 94% by mol of SrTiO.sub.3, 1 to 22% by mol of Bi.sub.2 O.sub.3 and 5 to 69% by mol of TiO.sub.2, and further including 0.1 to 20% by weight of MgO with respect to the total weight of the above-mentioned three compounds SrTiO.sub.3, Bi.sub.2 O.sub.3 and TiO.sub.2, whereby the ceramic dielectric composition has a high dielectric constant and a low dielectric loss and further the variations of the dielectric constant and the dielectric loss with respect to the variation of an applied voltage, are respectively, very small.

Abstract: The disclosed process combines preparatory biocidal treatment, water repellency treatment, and electrical conductivity treatment "in-line" with electrostatic spray coating of wooden articles. The preparatory treatment can be a single step, e.g. immersing a continuously moving line of wooden articles in a treatment bath containing a solution especially designed for this process. The solution is very low in solids (e.g. less than 20%, preferably less than 10%), and the solvent for these solids contains some polar solvent.

Abstract: In the well-known technique of disinfecting caries-infected or potentially caries-infected dental tissue with silver nitrate, silver thiocyanate or its complexes have been substituted for silver nitrate with excellent disinfecting results and lowered side effects, e.g., with lowered toxicity toward dental tissues and mouth membranes and less blackening of exposed portions of the teeth.

Abstract: Fluoroacylation of ethyl cellulose has been found to result in good gas permeability and blood compatibility for polymeric layers made from the resulting fluorinated esters. The fluoroacylated ethyl cellulose has good hydrolytic stability at blood pH and under sterilization conditions (e.g. 100.degree. C). For use in blood oxygenation devices, implantable biomedical devices, blood sampling or analysis or purification devices, etc., it is preferred that the fluoroacylated ethyl cellulose be substantially free of residual OH and have a fluorine content above 10% by weight (e.g. at least about 12% by weight).

Abstract: Fabrics are treated in machine drying apparatus to reduce static electricity carried by the fabrics, soften the fabrics and improve other fabric properties. A reusable dispenser of solid or semi-solid fabric-conditioning agent is placed within the dryer drum and the fabrics are tumbled in the dryer thereby causing some of the fabric-conditioning agent to be transferred to the fabric. When the dryer is heated, the heat of the dryer helps cause the fabric-conditioning agent to soften and assist in its distribution over the surface of fabric with which it is brought into tumbling contact.

Abstract: This invention concerns an improved measuring and mixing process and installation, in which the products are circulated by a system operating as a hydropneumatic convertor, and a batcher consisting of a cylinder containing a mobile piston is placed between this circulating system and the mixing tank.It concerns in particular the measuring and mixing of products of widely different viscosities and densities.

Abstract: Non-conductive substrates are prepared for electrostatic coating by pre-treatment with a conductivity-improving composition comprising an alkali metal hydroxide (less than 5 wt. %) and a solvent system for the alkali metal hydroxide comprising a lower alkanol and a hydrocarbonaceous co-solvent. The solvent system flashes off rapidly, but electrical conductivity is not lost. Consequently, production line electrostatic coating techniques can be used, and the residual solvent system does not generally have an adverse effect upon adherence of the electrostatically-sprayed coating to the substrate.

Abstract: In the disclosed process, the winning of noble or relatively electronegative metals (e.g. Au, Ag, Cu, Ni, etc.) from substantially aqueous solutions containing ions of the metal through the use of relatively electropositive precipitant metals (e.g. Fe, Zn, Al, etc.) is carried out along with recovery or utilization of some of the energy which can be produced by chemical or electrochemical action. In this process, an electrochemical primary cell-like arrangement with a one-fluid or two-fluid electrolyte (wherein the precipitant metal can be an anode) can also provide improvements in the character (orderliness, efficiency, purity of product, etc.) and control of the cementation reactions. For example, bright (high purity) copper can be obtained in a cathode compartment in a two-fluid cell using a scrap iron anode, a pregnant hydrometallurgical cuprous or cupric leach solution as the catholyte, and an external circuit connecting the cathode to the anode.

Abstract: The disclosed heterogeneous hot-melt sealant system is particularly well suited to sealing the typical tongue-and-groove joint between the base and cover of a burial vault. The hot-melt system comprises a plurality of layers, each layer being a distinct phase which resists chemical or morphological penetration (e.g. paraffin oil migration) from the adjacent layer. The layers are typically applied to the groove in the cover for the vault by individual casting or pouring of each of a plurality of hot-melt compositions in the molten state. Each hot-melt composition comprises an essentially amorphous polypropylene, a hydrocarbon resin (e.g. synthetic terpene resin), and a hydrocarbon (e.g. paraffin) oil. The first (bottom) poured hot-melt contains more polypropylene and less oil and terpene resin than the second (upper) pour.

Abstract: The sugar content of sweet corn can be increased without seriously reducing the water soluble polysaccharide (WSP) by using the shrunken.sub.2 (sh.sub.2) gene. Combining a sweet corn which is a homozygous sugary.sub.1 (su.sub.1) inbred with a sweet corn (homozygous su.sub.1 sh.sub.2) inbred will result in heterozygous hybrid that has approximately 50% more sucrose, 33% more total sugars and a WSP (water soluble polysaccharide) level near that of sweet corn) homozygous su.sub.1). The high WSP and sucrose levels are particularly desirable in food processing industries such as the canning and freezing industries.
