Abstract: A device for removing pipe attached to a fitting includes cutting apparatus for removing the pipe disposed within the fitting. A wrench apparatus is connected to the cutting apparatus for gripping the fitting to prevent its movement when the cutting apparatus is activated. Alternatively, this device may be used as a reaming device which permits radial movement of the cutting blades into engagement with a pipe after the cutting blades have been inserted within the pipe.

Abstract: A fluid sprayer apparatus attachable to an aircraft comprising a center section nozzle tube, a pair of detachable extension nozzle tubes connected to said center nozzle tube by quick disconnect fixtures, a manifold tube for supplying spray fluid to said nozzle tubes, said spray nozzle tubes having a plurality of inlet fittings spaced along their lengths and a plurality of pressure operated spray nozzles each removably attached to one of said fittings, said nozzles comprising a body member, a plunger slidably received in said body member with a pressure piston extending into said fitting, said plunger carrying a seal member engagable with the outlet end of said fitting to close said nozzle to fluid flow and a control insert unyieldably holding said seal member in sealing engagement with said inlet fitting when in a first position and yieldably holding said seal member in sealing engagement with said inlet fitting when in a second position whereby said nozzle may be opened to fluid flow by fluid pressure agains

Abstract: For use in hydraulic workover operations for oil and gas wells, a snubbing element is provided that is made entirely of polymeric material such as polyurethane. According to a preferred embodiment of the invention, the strength and rigidity supplied to the snubbing element in the prior art metallic support ring is now provided by molding that portion of the polymeric annular snubbing element from a polymeric material having a higher density and hardness than that of the polymeric sealing member. The polymeric annular snubbing element thus comprises a high density polymeric support member and a relatively lower density polymeric sealing member.

Abstract: Apparatus for imparting thermal energy to or removing thermal energy from a food product, said apparatus comprising intensive and semi-intensive thermal treatment sections and at least one equilibrating section.

Abstract: Stable diesel fuel emulsions of the water-in-oil type comprising from about 97 to about 90 volume percent of a mixture of a major amount of usual diesel fuel and a minor amount of at least about 5 volume percent of an aqueous solution of methanol, ethanol or a mixture thereof, and from about 3 to about 10 volume percent of an emulsifying blend of sorbitan monooleate and a water soluble, ethoxylated, non-ionic surfactant; and a process for producing such stable emulsions comprising adding while stirring the aqueous alcohol solution to a mixture of diesel fuel and emulsifying blend.

Abstract: Apparatus adapted to deliver a temperature-controlled gas from a common plenum to at least two thermal treatment zones is provided. The subject apparatus is adapted to direct columnated jets of a temperature-controlled gas so as to impinge on at least one surface of food products passing through such zones, and is further adapted to convey food products through such zones in multiple passes in which the food products are subjected to different thermal energy transfer rates in at least two of such zones.

Abstract: A releasable closure device adapted to provide sealing engagement between abutting surfaces by means of a rotatable locking ring comprising a plurality of locking lugs adapted to frictionally engage recessed locking channels disposed in said surfaces.

Abstract: An inker for a lithographic printing press in which ink and dampening fluid are applied to the printing plate by a resilient applicator roller. A resilient ink metering member having a flat metering surface is mounted on a support member which is movable to adjust the angle of intersection of the metering surface relative to a plane tangent to the roller surface. A doctor blade is mounted to remove dampening fluid from the roller surface and is actuated to an operative position upon actuation of the dampener to apply dampening fluid to the applicator roller.

Abstract: A method and apparatus to ink and dampen a lithographic printing plate wherein one or more of four disclosed embodiments of a dampening fluid evaporator device directs a continuous stream of air or other drying fluid along the length of a single resilient inking form roller (22) to remove dampening fluid from the roller (22) while leaving substantially dry ink on the roller surface.

Abstract: Disclosed is a process for modifying accumulated cross-linked polymer in an apparatus used for the production of a vinylaromatic compound, comprising optionally softening the polymer with an organic solvent; precipitating the polymer with a light, polar non-solvent for the polymer and expanding the softened polymer by bringing the softened polymer in contact with steam whereby the polymer is converted into a state which enables it to be more easily removed from the apparatus.

Abstract: An exercising device comprising a frame, actuating means, and a double acting hydraulic cylinder used therewith. The hydraulic cylinder includes a container having first and second chambers and passageways for placing the chambers in fluid communication with one another. A piston is slideably mounted within the first chamber and valve means are mounted with the container for preventing fluid communication into the first chamber when the piston is moved in a first direction and for preventing fluid communication around the piston when the piston is moved in a second direction. A piston rod extends into the container for moving the piston in response to movement of the actuating means. A control means governs the fluid flow through a selected passageway from the first to the second chamber to regulate the amount of force necessary to move the actuating means during exercise of a portion of the body.
