摘要:
THIS DISCLOSURE INVOLVES ESTERS OF HYDROXYPROPYL CELLULOSE AND HYDROXYPROPYL STARCH, SPECIFICALLY THE ACETATE AND LAURATE. THESE CELLULOWE ESTERS ARE USEFUL AS GELLING AGENTS FOR ORGANIC SOLVENTS. THE HYDROXYPROPYL CELLULOSE ACETATE IS PREPARED AT LOW COST UNDER MILD CONDITIONS AND IS PARTICULARLY USEFUL IN GELLING METHYLENE CHLORIDE (USEFUL IN PAINT STRIPPING) AND METHYL AND ETHYLENE BROMIDE (USEFUL AS SOIL FUMIGANTS). THE HYDROXYPROPYL CELLULOSE AURATE IS PARTICULARLY USEFUL AS A GELLING AGENT FOR JET FUEL.
摘要:
A fuel for a magneto-hydrodynamic generator in which readily ionizable seed material additives and power-increasing additives are suspended simultaneously in a liquid fuel carrier system whereby the suspension is stabilized in the form of a thixotropic gel by the addition of a suspension agent.

1. THE PREPARATION OF A GELLED HYDROCARBON PRODUCT WHICH COMPRISES DISSOLVING IN A NORMALLY LIQUID HYDROCARBON 1-10% BY WEIGHT OF SAID LIQUID HYDROCARBON, OF A SYNTHETIC HYDROCARBON ELASTOMER, HAVING AN APPRECIABLE DEGREE OF UNSATURATION, SOLUBLE THEREIN , ADDING TO THE SOLUTION THUS OBTAINED A CATALYST EFFECTIVE TO CAUSE REACTION BETWEEN AN OLEFINIC COMPOUND AND SULFUR DIOXIDE IN A PROPORTION EFFECTIVE TO CAUSE REACTION, THEN ADDING 0.520% BY WEIGHT, OF SAID ELASTOMER, OF SULFUR DIOXIDE TO THE RESULTING MASS AND THEN ALLOWING THE MASS TO REACT AND TO STAND UNTIL GEL FORMATION OCCURS, TH SAID ELASTOMER BEING SELECTED FROM THE GROUP CONSISTING OF A HOMOPOLYMER OF A CONJUGATED DIENE AND COPOLYMERS OF A CONJUGATED DIENE WITH AT LEAST ONE OF STYRENE, ALKYL-SUBSTITUTED STYRENES, METHYL ACRYLATE, METHYL METHACRYLATE, METHYL VINYL KETONE, ACRLONITRILE, METHACRYLONITRILE. 24. A GELLED HYDROCARBON COMPOSITION CONTAINING A NORMALLY LIQUID HYDROCARBON AND A SMALL PROPORTION OF A SYNTHETIC ELASTOMER HAVING AN APPRICIABLE DEGREE OF UNSATURATION THEREIN,A CATALYTIC PROPORTION OF A CATATYST EFFECTIVE TO CAUSE A REACTION BETWEEN AN OLEFINIC COMPOUND AND SULFUR DIOXIDE, AND SULFUR DIOXIDE, AT LEAST A PORTION OF SAID HYDROCARBON, SULFUR DIOXIDE, SYNTHETIC ELASTOMER AND CATALYST BEING PRESENT AS A REACTION PRODUCT OF SAID SULFUR DIOXIDE AND SAID SYNTHETIC ELASTOMER IS SAID HYDROCARBON AND AT LEAST A PORTION OF THE SAID HYDROCARBON, ELASTOMER AND SULFUR DIOXIDE BEING PRESENT IN SAID COMPOSITION IN A PHYSICAL GEL STRUCTURE; THE SAID ELASTOMER BEING SELECTEDD FROM THE GROUP CONSISTING OF A HOMOPOLYMER OF A CONJUGATED DIENE AND COPOLYMERS OF A CONJUGATED DIENE WITH AT LEAST ONE OF STYRENE, ALKYL-SUBSTITUTED STYRENES, METHYL ACRYLATE, METHYL METHACRYLATE, METHYL VINYL KETONE, ACRYLONITRILE, METHACRYLONITRILE.
摘要:
1. A flame thrower fuel consisting essentially of gasoline, natural rubber latex about .05 percent to 1.5 percent by weight of a nonionic surface active agent selected from the group consisting of polyoxyethylene sorbitan trioleate, polyoxyethylene sorbitan dioleate and polyoxyethylene sorbitan monooleate, and from 15 to 40 percent by weight of the said latex of a pour point depressant selected from the group consisting of ethylene glycol, glycerine and formamide said latex having not less than 60 percent by weight of rubber solids, in such quantity that the rubber solids content of the said fuel is 3 to 17 percent by weight.
摘要:
THIS INVENTION RELATES TO AN INEXPENSIVE, NON-TOXIC, STORABLE CHEMILUMINESCENT MASTERIAL PRODUCED BY THE REACTION OF CALCIUM DISILICIDE AND A HALOGEN-CONTAINING CARBOXYLIC ACID REACTANTS. THE HALOGEN CONTAINING CARBOXYLIC ACID OR A MIXTURE OF AN INORGANIC HALOGEN ACID AND A CARBOXYLIC ACID. A REACTIVATABLE, HIGH INTENSITY COLORED LIGHT IS PRODUCED WHEN THE CHEMILUMINESCENT MATERIAL IS MIXED WITH AN OXIDIZER SOLUTION.
摘要:
1. A THIXOTROPIC COMPOSITION CONSISTING ESSENTIALLY OF A MIXTURE OF FINELY DIVIDED PARTICLES SELECTED FROM THE GROUP CONSISTING OF METAL PARTICLES AND METAL HYDRIDE PARTICLES IN A LIQUID HYDROCARBON, GELLED BY ADMIXTURE THEREWITH OF (A) 98-90% BY WEIGHT OF A MONOESTER OF A HYDROCARBYLTHIOMETHYL PHOSPHONIC ACID AND A C1-18 ALKANOL AND (B) 2-10% BY WEIGHT OF A DI- TO TRI-BASIC PENTAVALENT PHOSPHORUS ACID HAVING FROM 0 TO 1 MONOHALOALKYL SUBSTITUENTS, WHEREIN THE ALKYL GROUP CONTAINS FROM 1 TO 4 CARBON ATOMS.
