Abstract: A hydraulic system for use in a work vehicle with a powered implement is disclosed. In one embodiment, the hydraulic system may include a first hydraulic circuit including a first hydraulic pump with a low pressure and low flow output, switch and valve; a second hydraulic circuit including a second hydraulic pump with a high flow and high pressure output, switch and valve; and a third hydraulic circuit including a third hydraulic pump with a high flow and high pressure output, switch and valve. The first, second, and third circuits each include an output selectively combinable with each other by an operator control which controls the switch and valve configurations. The hydraulic system has several configurations.

Abstract: A mechanism for moving an element in opposite directions includes a piston connected with the element. The piston reciprocates in a cylinder as high pressure fluid is alternately directed against one side or the other of the piston by a rotatable directional valve. The directional valve is rotated by a gerotor motor. A single rotatable valve element has passages at one end which form a commutator valve for the gerotor motor and ports at the other end which form the directional valve. A passage through the valve element connects the output of the gerotor motor with the directional valve ports. Cushioning means are provided to damp the motion of the piston at each end of its stroke to prevent impact with the ends of the cylinder.

Abstract: A liquid flame retardant composition consisting essentially of:A. A polybrominated diphenyloxide containing about 4 to 9 nuclearly substituted bromine atoms and;B. A C.sub.10-24 aliphatic hydrocarbon polybrominated and polychlorinated to contain about 10 to 50 weight percent of bromine and about 5 to 60 weight percent of chlorine; the weight ratio of A to B ranging from about 5:1 to 1:5, optionally combined with a flame-retardant synergist such as antimony oxide.

Abstract: A latex otherwise unstable to diammonium phosphate may be improved by the addition of an effective flame-retardant amount of an additive which comprises from one to five parts by weight of ammonium bromide to one part by weight of diammonium phosphate.

Abstract: A composition consisting essentially of an olefin polymer and a plasticizer therefor of the formula ##STR1## wherein R represents alkyl, aryl, ##STR2## X represents halogen; and N REPRESENTS THE INTEGERS 4 OR 5.The composition is useful in plastic molding and forming processes to make articles of manufacture.
