Abstract: An exercise device including a shaft and a pair of movable sleeves positioned about opposite ends of the shaft. Each sleeve includes a handle rotatably mounted to the sleeve. The shaft includes a detent device associated with at least one sleeve. The detent device permits that sleeve to be releasably positioned along the shaft and for the position of the sleeve to be selectively changed so that the spacing between the handles may be changed. The sleeve may also be rotatable about the shaft while held longitudinally by the detent device. The handles may be rotated about members extending generally perpendicular to a centerline of the shaft and the members may be received within bushings in a wall of the sleeve.

Abstract: A solvent extraction composition comprising one or more orthohydroxyarylaldoximes and/or one or more orthohydroxyarylketoximes, and one or more selectivity modifiers consisting of phosphinic and/or phosphonic acids, and salts and esters therefore and optionally one or more equilibrium modifiers is provided.

Abstract: An articulated bed assembly includes a stationary frame structure to which an upper body support section and a lower body support section are pivotably mounted for movement between raised and lowered positions. An actuator arrangement includes an actuator member which is adapted for extension and retraction in response to operation of an operating arrangement such as a drive motor. The actuator member is interconnected with the upper body support section through a drive member for raising and lowering the upper body support section in response to extension and retraction of the actuator member. An operating mechanism is interconnected between the actuator member and the lower body support section for lifting and lowering the lower body support section in response to extension and retraction of the actuator member. The operating mechanism includes a linkage arrangement defining a first link pivotably mounted to the stationary frame assembly and a second link pivotably mounted to the actuator member.
