    摘要: The method and two devices provide for the underground connection of pipe with minimal disruption of the surrounding landscape. A main pipe is cleaned by a surface preparation tool designed to access the main pipe through a small hole. An adaptor is attached to a second pipe, and then placed in a clamping device designed to access the main pipe and clamp the adaptor thereto through the small hole. Electricity is passed through the adaptor, thereby softening the plastic so that this softening and the pressure of the clamp secures the adaptor to the main pipe. The main pipe is then pierced by the adaptor's tapping tee.

    摘要: An apparatus for precision linear positioning of material along a frame, having carrier means for carrying the material juxtaposed above the frame, means for linearly moving the carrier means along the frame having a plurality of pneumatic cylinders each having an extendable and rectractable piston, the cylinders connected to each other in a series and including a first end pneumatic cylinder attached to the frame and a last end pneumatic cylinder attached to the carrier means, such that the carrier means is moved by the amount of the cumulative extension and retraction of the pistons, stopping means associated with each the pneumatic cylinder for limiting the extension of each the piston, and means for providing a controllable amount of air to each pneumatic cylinder to selectively control extension and retraction of each piston.

    摘要: A drilling apparatus mounted on and traveling step by step along a track mounted on a work panel and drilling a row of spaced holes in the panel in accordance with the spacing of positioning slots in a template on the track. A collet-type clamp unit trails the drill unit and clamps the drill unit against the panel prior to each drilling operation, the drill unit being adjustable in two perpendicular planes so as to be normal to the surface to be drilled. Two latching mechanisms are fixed respectively to the drill unit and the clamp unit to locate these units along the track, and a reciprocating actuator steps first the drill unit and then the clamp unit to successive positions along the template.
