Abstract: Residual fuel oil conditioners comprising an aqueous solution of (a) from 2.0 to 20.0% by weight of at least one water soluble metal salt selected from the halides, sulfates, and nitrates of magnesium, manganese, zinc, copper, lead, iron, nickel, aluminum, calcium and barium; and (b) from 0.1 to 25.0% by weight of a surfactant, preferably a nonionic surfactant having an HLB of from 12 to 17.

Abstract: The instant invention is directed to a method for preventing the formation of scale in sugar evaporation equipment comprising adding to the juice from 0.1 to 200 ppm of a polycarboxylic acid or its salt selected from the group consisting of polymaleic acid, amine adducts of maleic anhydride polymers, phosphonobutane tri-carboxylic acid, phosphinocarboxylic acids and copolymers of acrylic acid and an hydroxylated lower alkyl acrylate.

Abstract: The instant invention is directed to a method for reducing the viscosity of magnesium hydroxide filter cake paste which comprises adding an anionic polymer or copolymer to the magnesium hydroxide filter cake paste. The instant invention is also directed to a stable magnesium hydroxide dispersion comprising an anionic polymer, water and magnesium hydroxide.

Abstract: Composition containing organic magnesium and organic manganese compounds as a fuel conditioner to reduce fuel requirements and sulfur trioxide emissions and method of using same.

Abstract: Use of methoxypropylamine as a neutralizing amine in combination with hydrazine to prevent corrosion in steam condensate systems or in other low solids aqueous systems.

Abstract: A potentiometer and switch assembly wherein the potentiometer resistance is deposited on a circuit board. The control member of the assembly comprises a shaft having a rotor mounted thereon, attached to which is a wiper for contacting the resistance. The switch mechanism includes a cam shaft adapted to be engaged by the rotor whenever the control shaft is pushed. The cam shaft is positioned to the side of the rotor and is rotated through a predetermined angle each time the control shaft is pushed. Camming surfaces on the cam shaft contact one member of the switch contact pair to alternately cause that contact pair member to open and close the switch. The cam shaft may be arranged to contact a second switch contact pair which opens and closes oppositely to the first switch contact pair so that a three-way switching function may be effectuated.

Abstract: Apparatus for testing a pipe under internal fluid pressure for leakage or structural integrity includes an elongate, hollow mandrel having one end sealed by a fixed seal. A shiftable seal is adapted to advance a pipe to be tested so that the other end of the mandrel is inserted through one end of the pipe to a testing position. The shiftable seal includes a pressure plate and a plug, the pressure plate sealing the other end of the pipe and the plug insertable within the other end of the mandrel for sealing it when the mandrel is in the testing position. The shiftable seal further includes a frame assembly movable along tension beam members, the assembly being selectively lockable thereto. The pressure plate is mounted on the assembly and is adapted to be selectively extended from or retracted toward the assembly.
