    Abstract: Polyolefin pipes are welded end-to-end by a self-propelled, self-contained machine which performs all steps necessary to the process without need for any other machines or equipment. Hydraulically driven parallel tracks are independently controlled for maximum maneuverability. An hydraulically driven, computer controlled, reversible jaw assembly reciprocates the new pipe section relative to the exiting pipe line. A facer for trimming and squaring the pipe ends to be joined and a heater for melting the pipe ends for fusing are umbilically connected to the machine for on-board or remote operation. The computer, also on an umbilical, enables the operator to operate the machine in a normal mode in which the operator manually controls the facing, soaking and fusing processes or an automatic mode in which the fusing process is automatically controlled by the computer. The computer also allows the operator to choose a data logging mode in which the operating pressure, heater temperature and time data are recorded to provide a history for each joint made by the machine.

    Abstract: A hydraulic machine is disclosed in several embodiments as a pump, as a motor, and as a combination pump/motor. The machine's fixed cylinders are positioned circumferentially to a drive shaft, the pistons being driven by, or acting against, a split swash-plate which is supported primarily by the same main bearing in which the drive shaft rotates. The inclination of the split swash-plate is adjusted by an axially-movable servo mechanism which is also arranged circumferentially to the drive shaft. Preferred embodiments include, among other features, (i) various gimballed-yoke supports for the non-rotating portion of the swash-plate, (ii) various designs for a rotating valve-plate, and (iii) a radial valve system. The unique arrangement of elements provides a machine that is remarkably compact and lightweight, being (a) significantly smaller than commercially-available machines having similar horsepower ratings and (b) operable hydrodynamically (i.e., at constant horsepower) at reduced speeds. In one preferred embodiment, pump and motor units are mounted side-by-side within a combined housing having integrated fluid passageways for transferring operating fluid between the units, and the combined housing itself is mounted within a surrounding reservoir.

    Abstract: A process to form a continuous fin helically around the exterior of a cylindrical tube by rotation of a primary forming roller and rotation of a contiguous spindle roller. The process includes advancing and inserting the fin in a gap between the primary forming roller and the spindle roller. The gap between the primary forming roller and the spindle roller is closed and the fin is tightly gripped therebetween. The tube is axially moved for a first, chosen length, while, at the same time, the tube is rotated at a first speed, the primary forming roller is rotated at a first speed and the spindle roller is rotated at a first speed. Thereafter, the tube is axially moved for a second, chosen length, while, at the same time, the tube is rotated at a second speed, the primary forming roller is rotated at a second speed, and the spindle roller is rotated at a second speed.
