No. 916,966 filed 19 June 1978, now U.S. Pat. No. 4,179,468 dated 18 Dec. 1979 and entitled Cyclic Terpenoid Onium Salts, Their Preparation and Uses.
Abstract: Novel isocyanates such as, for example, blocked L-tyrosine methyl ester isocyanate, are reacted with compounds of biological, clinical interest or the like such as, for example, digoxin, to form derivatives receptive to tagging, as by radioliabeling. The tagged derivatives may then be employed to determine the presence of the compound of interest in nanomolar or even picomolar amounts by using clinical analysis techniques such as radioimmunoassay.

Abstract: Organic ethers including polyethers having two CH.sub.2 .dbd.C(R)CH.sub.2 -- end groups per molecule wherein R is a monovalent hydrocarbon group are reacted with organohydrosiloxanes under hydrosilation reaction conditions in the presence of a platinum catalyst preferably a neutral platinum catalyst, to form very useful nonhydrolyzable siloxane block copolymers. Novel nonhydrolyzable linear block copolymers substantially free of silicon-bonded hydrogen are obtained with linear dihydropolyorganosiloxane reactants and linear ethers or polyethers. The linear block copolymers made with the linear dihydrosiloxanes and polyethers are particularly useful as surfactants and foam stabilizers for the preparation of polyurethane foams. The very low degree (if any) of isomerization of the CH.sub.2 .dbd.C(R)CH.sub.2 -- group to unreactive species during the hydrosilation reaction results in the unexpectedly high molecular weight of the copolymers of the present invention.

Abstract: Alkoxysilyl ethers of 1,3-dicarbonyl cyclic compounds, such as methoxy tris-5,5-dimethyl-cyclohexen-2-one-3-yloxy silane can be made by effecting reaction in the presence of an acid acceptor between an alkanol, a halosilane and a 1,3-dicarbonyl cyclic organic compound, for example, 5,5-dimethyl-1,3-cyclohexane dione. The alkoxysilyl ethers are useful as vulcanizing agents for silanol terminated polydiorganosiloxanes.
Abstract: Reactions of chlorosilanes and methoxysilanes with chlorosiloxanes, methoxysiloxanes and siloxanes are carried out in the presence of hydrochloric acid and methanol, without the addition of any catalyst, to provide methoxy-functional polysiloxane intermediate fluids.

Abstract: Carboxylic acid acylating agents are derived from polyalkenes such as polybutenes, and a dibasic, carboxylic reactant such as maleic or fumaric acid or certain derivatives thereof. These acylating agents are characterized in that the polyalkenes from which they are derived have a Mn value of about 1300 to about 5000 and a Mw/Mn value of about 1.5 to about 4. The acylating agents are further characterized by the presence within their structure of at least 1.3 groups derived from the dibasic, carboxylic reactant for each equivalent weight of the groups derived from the polyalkene. The acylating agents can be reacted with a further reactant subject to being acylated such as polyethylene polyamines and polyols (e.g., pentaerythritol) to produce derivatives useful per se as lubricant additives or as intermediates to be subjected to post-treatment with various other chemical compounds and compositions, such as epoxides, to produce still other derivatives useful as lubricant additives.
Abstract: An improved process for the production of an aminoalkylsilane by reaction of a chloroalkylsilane with ammonia or alkylamine at an elevated temperature or pressure wherein the chloroalkylsilane is added in a less than stoichiometric ratio to the ammonia or alkylamine preheated in a pressure vessel at a temperature between 50.degree. and 200.degree. C. Thereafter the reaction is carried out in a known manner within the temperature range of 50.degree. to 200.degree. C. By this manipulative technique, a higher yield of aminoalkylsilane is obtained per unit of time and the aminoalkylsilane is obtained in a greater purity.
Abstract: A process for preparing a gamma amino propyl alkoxy silane of the formula ##STR1## wherein R is an alkyl moiety of 1 to 4 carbon atoms, R' is methyl or phenyl, and y is 0, 1 or 2 which comprises contacting the corresponding gamma-chloropropyl alkoxy silane with ammonia under pressure at a temperature between 50.degree. and 90.degree. C. while stirring the reaction mixture.
Abstract: Solid carbonaceous material is hydrocracked to provide aliphatic and aromatic hydrocarbons for use as gaseous and liquid fuels or chemical feed stock. Particulate carbonaceous material such as coal in slurry with recycled product oil is preheated in liquid state to a temperature of 600.degree.-1200.degree. F. in the presence of hydrogen gas. The product oil acts as a sorbing agent for the agglomerating bitumins to minimize caking within the process. In the hydrocracking reactor, the slurry of oil and carbonaceous particles is heated within a tubular passageway to vaporize the oil and form a gas-solid mixture which is further heated to a hydropyrolysis temperature in excess of 1200.degree. F. The gas-solid mixture is quenched by contact with additional oil to condense normally liquid hydrocarbons for separation from the gases. A fraction of the hydrocarbon liquid product is recycled for quenching and slurrying with the carbonaceous feed.

Abstract: Fluctuations in concentration of the starting materials during continuous diazotization are taken into account by passing a component stream from the receiver to the diazotization vessel through an analyser where, for a short residence time, the nitrite content is determined by an electrochemical measuring technique. A required nitrite excess is adjusted in the receiver on the basis of this measurement. By virtue of the pH-value, however, a diazotization reaction still does not take place in the receiver.
Abstract: A skin construction suitable for use as a high temperature airfoil surface that includes a metallic member having first and second corrugations. The first corrugations have a size and spacing which permits resilient thermal expansion of the member in a direction transverse to the direction of the first corrugations. The second corrugations are positioned in a direction that is substantially transverse to the direction of the first corrugations and the second corrugations have a size and spacing which permits resilient thermal expansion of the member in a direction generally transverse to the direction of the second corrugations.An imperforate metallic surface is integral with the metallic member. Thermal stresses imposed on the skin construction are, thus, absorbed by deformation of the first and second corrugations which act as expansion joints in permitting controlled expansion of the skin construction.
