Abstract: A portable cooling or heating system suitable for use on vehicle such as a car, plane or boat, that does not have its own air conditioning system. The system is intended to be combined with a portable cooler chest and includes an electric fan unit that can be powered from the power supply on a vehicle. The cooling is provided by ice and the like. The system can also be used to heat a confined space by placing a hot material in the chest.

Abstract: Method of inhibiting polymerization of alkenyl monomers comprising contacting the alkenyl monomers with: wherein R1 and R2 independently of one another are alkyl, phenyl, aryl, alkoxy, or carboxy groups; and oxygen. Mixture comprising: a) alkenyl monomers with:  wherein R1 and R2 independently of one another are alkyl, phenyl, aryl, alkoxy or carboxy groups; and c) oxygen.

Abstract: The present invention provides compositions and methods which are effective to prevent corrosion of metal surfaces involved in refining solutions having relatively high partial pressures of carbon dioxide. The compositions of the present invention comprise mixtures of a pyridinium quaternary salt and an organic compound, such as thiourea, which contains at least one sulfur atom double bonded to a carbon atom. The compositions are added substantially continuously to the solution to be treated to result in a final concentration of at least about 30 ppm of pyridinium quaternary salt, preferably between about 56-70 ppm, and at least about 5 ppm double bonded sulfur containing compound, preferably between about 10-13 ppm.

Abstract: Sour sulfhydryl-group containing oils are treated with an amount of hexamethylenetetramine effective to sweeten the oil and reduce headspace H.sub.2 S to a desired level.

Abstract: Novel organic water-soluble antimony compounds are prepared by reacting an alkoxyalkylamine with a hydroxycarboxylic acid to form an intermediate product and then reacting the intermediate product with an antimony oxide. These compounds are useful for use as catalyst metal poison passivators.

Abstract: Novel organic water-soluble antimony compounds are prepared by reacting an alkanolamine with a hydroxycarboxylic acid to form an intermediate product and then reacting the intermediate product with an antimony oxide. These compounds are useful for use as catalyst metal poison passivators.

Abstract: Novel organic water-soluble antimony compounds are prepared by reacting ammonia or an alkylamine with a hydroxycarboxylic acid to form an intermediate product and then reacting the intermediate product with an antimony oxide. These compounds are useful for use as catalyst metal poison passivators.

Abstract: Cleaning apparatus employing an abrasive laden water jet including a tank for water and abrasive, an eductor in the tank to one inlet of which a water supply is connected and another inlet of which is open to the water abrasive mixture, a mechanism, which may be the eductor, to fluidize the abrasive in the water in the tank, a line from the outlet of the eductor to a working nozzle which is supplied with water and abrasive mixture by the action of the water supply in the eductor, and a high pressure water line adjacent the nozzle to increase the velocity of flow of the mixture from the nozzle.

Abstract: Antimony tricarboxylates of higher carboxylic acids can be prepared in high yields by(a) reacting antimony oxide with an anhydride of a lower organic acid,(b) reacting the product from (a) with at least one higher carboxylic acid at a temperature sufficient to vaporize volatile material and removing the vaporized volatile material,(c) simultaneously passing a stream of an inert gas through the reaction mixture, and(d) recovering the antimony tricarboxylate of said higher carboxylic acid.

Abstract: A method for determining the concentration of the desired component of a system which comprises adding a predetermined amount of an easily analyzable auxiliary chemical to the system, which when subjected to analysis, for example spectroscopic analysis, gives a quantitative determination of its concentration in the system; and then determining the concentration of the desired component by correlating the ratio of the auxiliary chemical to the desired component.
