Abstract: A product delivery system includes a product transport vehicle having at least a plurality of tank compartments, internal valves, control valves, fluid property sensors, temperature sensors, overfill sensors, pressure sensors, a system controller, and a memory module. The product delivery system may be operable to communicatively connect with the loading system at a loading station, a fleet management system, or a cloud system to obtain information, such as the amount of liquid product to be loaded into a tank compartment. The product delivery system may be operable to compare the volumes of the tank compartments with the amounts of liquid product to be loaded at a loading station and maintain the internal valve or control valve in a locked state or transition the internal valve or control valve to an unlocked state based on the comparison. Other comparisons based on liquid type or distribution tank volume can also be made.

Abstract: Disclosed are novel nitrogen containing heterocyclic compounds and novel vinyl terminated polyurethane/polyamide polymers together with the use of both of these compounds in a novel adhesive and coating composition. The nitrogen containing heterocyclic compounds of the invention contain two vinyl-terminated substituents and at least one carbamylmethyl substituent and have a nucleus selected from melamine, oligomers of melamine, benzoguanamine, and oligomers of benzoguanamine, glycoluril and oligomers of glycoluril. The vinyl terminated polyurethane compounds of the invention have a molecular weight of from about 3000 to about 80000, and contain at least two vinyl end groups.

Abstract: The binder composition of this invention contains a beta-hydroxy urethane functional material and a polycarboxylic acid. Coated glass fibers are prepared by contacting said fibers with the binder composition of the invention and thereafter curing the composition. This invention is also an improved method of treating glass fibers by contacting them with the improved binder composition of the invention.

Abstract: A process is disclosed for the preparation of aralkyl mono- and diurethanes or ureas by carbamylmethylation, or acid-catalyzed addition at a temperature of 40.degree. C. to about 100.degree. C. of formaldehyde and esters of carbamic acid to aromatic hydrocarbons. Aralkyl carbamates and ureas formed by this process can be cracked directly to produce aralkyl diisocyanates, or hydrogenated and then cracked to produce aliphatic diisocyanates, or reacted directly with polyols to produce polyurethanes by functioning as blocked isocyanates.

Abstract: The rate of set of an aqueous slurry of hydraulic cement can be retarded by means of an additive comprising a water-soluble polymer which contains hydroxamic acid pendant groups. Hydroxamated acrylamide polymers and copolymers are preferred additives for retarding set in cement slurries.

Abstract: A new and improved process for preparing tertiary aralkyl carbamates is disclosed. The process comprises reacting a mixture of a lower alkyl carbamate with a tertiary aralkyl halide at a temperature of about 50.degree. C. to about 100.degree. C. until formation of the tertiary aralkyl carbamate is substantially complete. In a preferred process, an alkenyl aromatic compound which is the olefin precursor of the aralkyl halide employed, is added to the reaction mixture to improve the yield of tertiary aralkyl carbamate products. The tertiary aralkyl carbamates prepared by the process of this invention are useful intermediates which may be thermally cracked in the presence of base catalysts to form tertiary aralkyl isoayanates.

Abstract: A process for production of tertiary aralkyl isocyanates by reaction at low temperatures of the corresponding halides with an excess of isocyanic acid. Manufacture of TMXDI is specifically contemplated.

Abstract: A conjugate for use in the detection and quantification of antibodies and antigens in body fluids by immunoassay procedures and chemiluminescent immunoassay procedures utilizing the conjugate. The conjugate is capable of reacting with an antigen or an antibody or both and includes a tag capable of catalyzing a chemiluminescent reaction. The conjugate may be an antibody or an antigen to which a metallo porphyrin tag is attached and preferably comprises immunoglobulin to which hemoglobin is attached.

Abstract: A process for production of tertiary benzyl isocyanates by reaction at low temperatures of the corresponding halides with an excess of isocyanic acid.

Abstract: A soluble, chiral, rhodium-containing catalyst which permits the catalytic reduction of prochiral 3-acyl-1-2-alkoxyethyl)-4-phenyl-2-imidazolinones to chiral 3-acylimidazolidinones with a substantial excess of the desired S optical isomer. The 3-acylimidazolidinones may in turn be substantially converted to levamisole, the S isomer of tetramisole. The resolution of tetramisole to remove the R isomer is thus avoided.
