A farm tractor includes differentials interposed in the front and rear axles of an agricultural vehicle. The differentials include hydraulically-operated locks each controlled by a solenoid-operated valve. The solenoid valves are controlled by a control circuit which includes a latching relay, a normally open manual switch operable only to close the relay and lock the differential and a pair of se...

A method for effecting logging or servicing operations in a predetermined zone of a well, following an initial portion thereof, comprising fastening a logging or servicing tool body at the end of a string of rods lowered into the well, said tool body being provided with an electric male connector, lowering at the end of an electric transmission cable, from the surface, a female connector adapted t...

The compressed spring acting on one end of the lever urges the lever in the direction to apply force to a pressure plate guided by the fixed bushings to apply pressure to the brake pads and discs to prevent rotation of a motor shaft received in the coupling. When the solenoid coil is energized, the armature lifts the end of the lever to relieve the pressure and release the brake. If the plunger at...

This invention covers a water soluble one-component fiberglass mat binder composition which comprises a urea-formaldehyde resin and polyvinyl acetate polymers and/or vinyl acrylic-polyvinyl acetate copolymers in the manufacture of asphalt shingles. The shingles of the invention are formed by the asphalt coating of a fiberglass mat in which the glass fiber mat has been coated with the binder compos...

A continuous process for making alkylene glycols by the hydrolysis of alkylene oxides in the presence of selectivity-enhancing organometalate wherein the alkylene glycol-containing hydrolysis product contains organometalate comprises recovering organometalate by extraction with a water-immiscible solvent, separating the resulting organometalate-containing solvent into an organometalate-lean stream...

The subject invention is a foamable composition based on a blend of a carbon monoxide- or sulfur dioxide-containing ethylene copolymer and a vinyl or vinylidene halide polymer, and the closed-cell foamed article produced therefrom.

A solvent-free curable composition has a long shelf life and consists of A 100 parts by weight of an epoxy resin and B from 10 to 100 parts by weight of, as a curing agent for the epoxy resin, an aromatic diamine containing groups, with or without C from 0.01 to 5 parts by weight of an accelerator, the curing agent for the epoxy resin being finely dispersed in the latter and preferabl...

A water miscible, stable, fluid product comprises particles above 20 microns in size of a high molecular weight polymer gel interconnected by a continuous phase that is an aqueous solution of an equilibrating agent that holds the water content of the particles in equilibrium with the water content of the aqueous phase and that prevents substantial agglomeration of the particles in the fluid produc...

A water soluble or swellable polymer gel is dispersed into a liquid phase to form a fluid composition and is worked while in that composition. The liquid phase is an aqueous solution of an equilibrating agent that substantially prevents aggregation of the particles or dissolution of the polymer during the working. The working may be, for instance, milling, extraction of impurities, extraction of w...
