A rotor assembly for extruding randomly shaped food items includes a one-piece finger member. The one-piece finger member reduces the downtime of the extruding machine containing the rotor assembly by reducing the number of parts in the rotor assembly and reducing the adjustment necessary after finger replacement. The proprietary threaded interface between the finger member and the improved extruder machine allows for quick swap out during extruder maintenance.

The golf car accessory includes a bag divider adapted for attachment to a golf car to separate bags placed in the golf car. A first arm extends upwardly from the bag divider and a second arm operatively connected to the first arm and extending outwardly to support a ball washer. Preferably the first arm is a telescoping arm so that the height of the ball washer is adjustable. Preferably the second arm is also a telescoping arm so that the horizontal position of the ball washer can be adjusted.

The invention comprises a polymeric demulsifier, methods of producing the demulsifier and methods of using the demulsifier. The demulsifier is the reaction product of at least one amine-containing group, and optionally a second amine-containing group which includes a tertiary amine group, with a diepoxy- or diglycidyl compound and an additional amine compound subsequently reacted with unreacted epoxy groups. This polymeric composition is subsequently reacted with N-alkylating agent containing compounds to produce novel demulsifiers useful to demulsify oil bearing formations.

Demulsifiers, their preparation and use in oil bearing formations

The corrosion of metal equipment which is cleaned with an inorganic acid is inhibited by treating the equipment with a corrosion inhibitor composition containing at least one quaternary ammonium compound, a sulfur-containing compound and a nonionic surfactant in a solvent.

Method of inhibiting corrosion of metal equipment which is cleaned with an inorganic acid

Corrosion inhibiting compositions and methods for inhibiting the corrosion of metal surfaces by corrosive aqueous fluids are provided. In accordance with the invention, a corrosion inhibiting composition comprised of one or more aldehyde oligomers having the general formula

Corrosion inhibiting compositions and methods

An acid corrosion inhibitor composition is provided for petroleum wells and water wells subjected to stimulation with acid solutions. The inhibitor combines cinnamaldehyde and an organo-sulfur compound. The inhibitor provides a reduced rate of corrosion and fewer instances of pitting than inhibitors which include cinnamaldehyde alone. The inhibitor does not suffer from the well-known oil field aldehyde/polyacrylamide crosslinking incompatibility. The enhanced performance by the inhibitor of the present invention is provided by a synergistic action between the cinnamaldehyde and an organo-sulfur compound.

A gelling agent for viscosifying liquid hydrocarbon fracturing fluids is an aluminum salt of a phosphate ester made by forming the ester by reacting P.sub.2 O.sub.5 with a mixture of organic alcohols which include high molecular weight alcohols or diols selected from hydroxy functional homopolymers, copolymer or terpolymer made from olefins and diolefins selected from the group consisting of ethylene, propylene, butene, butadiene, isoprene, and selected styrenes. The oil based fracturing fluid containing the gelling agent in sufficient concentration to provide a viscosity of between 50 cp and 350 cp at 100.degree. F.

EPDM elastomer is sulfonated and neutralized by a bulk process involving mechanical mixing at low temperatures in the sulfonating and neutralizing steps. The EPDM is discharged from the mixing process as finely divided particles having a low bulk density.

Elemental iodine is used to improve the performance of conventional corrosional inhibitors in oil field acidizing operations. The iodine, because of its solubility, may be used in a formulation which includes a corrosion inhibitor and surfactants dissolved in a suitable organic solvent.

Intensified corrosion inhibitor and method of use

Subterranean oil-bearing formations are treated with aqueous acid solutions which include an effective amount of an alkoxylated alkyl substituted phenol sulfonate which exhibits both antisludge and demulsification properties.

Surfactant additive for oilfield acidizing

A coalbed formation is stimulated to improve the recovery of methane which involves injecting into the coalbed formation an aqueous acid solution containing an organic amphoteric tertiary ammonium compound having from 1 to 3 tertiary ammonium groups, each N of which contains at least one C.sub.3 to C.sub.4 unsaturated carboxylic acid group, and wherein the compound contains a terminal benzyl or C.sub.5 -C.sub.19 alkyl group.

Stimulation of coalbed methane production

Granules containing a gel breaker are used in a well treatment involving the use of a gelled fluid. The granules exhibit delayed release of the breaker to permit placement of the gelled fluid into the subterranean formation. The method of the present invention is used in gravel packing operation to degrade polymeric gelling agents used in the gravel packing liquid.

Method of treating formations

A method of acidizing a subterranean formation with an acqueous acid solution wherein the acid solution contains corrosion inhibiting amounts of an amine derivative prepared by reacting an unsaturated carboxylic acid with (a) fatty amine or polyamine, or (b) a fatty amido amine or polyamine, or (c) a fatty imidazoline amine or polyamine. The derivative is characterized by the absence of primary amino groups, and preferably contains only tertiary amino groups.
