Abstract: A fitting for inserting a pig into a pipeline. The fitting comprises a cast body having a first end for connecting to a first end of a pipeline and a second end for connecting to a second end of the pipeline. The cast body further comprises a third end arranged at a predetermined angle to the first and second end of the cast body. A retractable guide within the cast body can be at least partially inserted into a run portion of the cast body for delivery or retrieval of the pig.

Abstract: A method for inductively heating a workpiece using a heating coil that surrounds the sides and ends of the workpiece, wherein the heating coil comprises a first coil assembly that encloses a first portion of the workpiece and a second coil assembly that encloses a second portion of the workpiece. A power supply is operatively connected to the first coil assembly and the second coil assembly.

Abstract: A variable focal length lens, for use in spectacles, is capable of variable power and astigmatism. It includes two independently controlled elastic cylindrical lenses which are mounted in series, usually but not necessarily at right angles to each other, on a common stiff transparent support. The lenses are each deformed by a pair of edge forces normal to each outer surface. The forces produce an essentially cylindrical shape of each outer surface. The two pairs of forces are independently controlled by two knobs conveniently located on the temple of the spectacles.

Abstract: A housing having a longitudinal aperature therethrough, and an exterior surface adapted to be securable to a container. A stem is longitudinally movable within the housing and is cooperatively conformed with the housing such that an annulus exists between a portion of the housing and the stem. The stem includes a plurality of ports allowing fluid communication between the annulus and a longitudinal cavity extending from the top end of the stem. A sealing instrumentality if included proximate a bottom end of the valve to prevent the flow of fluid into the valve annulus when the valve is in a first "closed" position. The stem is adapted to be moved longitudinally within the housing to a second, "open", position wherein the sealing instrumentality is released and fluid may enter the annulus and pass through the ports to exit the valve through the stem cavity.
