摘要： Electrical apparatus includes an outer enclosure, an electrode within the enclosure, and an insulating gas electrically insulating the electrode from the enclosure. A support plate is secured to the outer enclosure, and the support plate has an opening therein. A housing, containing valve means, is secured to the support plate adjacent the support plate opening. An end plate is secured to the end of the housing. The valve means in the housing are capable of being in two positions, a first position preventing the flow of gas past said valve means, and a second position wherein an opening which is through the valve means is aligned with the support plate opening.An opening is formed through the enclosure in the wall portion thereof which is in alignment with the support plate opening. The opening through the enclosure is formed without generating contamination particles within the enclosure and in a manner which minimizes escape of gas from the enclosure. Specifically, a pulling rod is welded to the outer wall of the enclosure, the support plate and valve means are secured to the enclosure with the pulling rod extending therethrough, a hollow tube having cutting means at the end thereof is positioned around the pulling rod, the cutting means is operated to effect only a partial cutting of the enclosure wall, and then a force is applied to the pulling rod to break out the portion of the enclosure wall partially cut by the cutting means. Thereafter, the pulling rod and cutting means are removed and the valve means is closed.

摘要： The embodiment of the invention disclosed herein is directed to a piercing valve structure for connection to a puncturable conduit to gain access to the interior of a closed refrigeration system for testing or applying refrigerant material into the system. The piercing valve has a cam lock collar member, extending from the valve body and a resilient pad located between the cam lock member and the valve body. The piercing valve is placed on the conduit and rotated approximately 90* about its longitudinal axis, which is perpendicular to the axis of the conduit, and thereby effects a sealing action of the area about the point to be pierced, a piercing action, and a locking action all in a single operation.

摘要： A cutter member for use in cutting a hole in plastic pipe having a thick wall or a thin wall. The cutter member is rotated and advanced with a positive predetermined lead against the pipe, the cutter member being so designed that after it has cut the initial chips off the outside curvature of the pipe, it cuts a continuous chip by a peeling action and the initial chips and continuous chip are discharged inwardly of the cutter member above the coupon being cut. The cutter member may be repeatedly used and it can be used with a drilling tool or machine or, for that matter, a tapping tee. The preferable drilling machine for use with the cutter machine is of simple construction, including a tubular body member, a two-piece boring bar with one member having threads thereon for positively advancing the cutter member, and the other member of the boring bar being adapted to receive the cutter member. The drilling tool is detachably attached to a pipe or to a fitting operatively connected to the pipe, the fitting having the usual passageway therethrough and the boring bar being arranged to extend through the passageway to the wall of the pipe to be cut. The drilling tool is provided with means where the boring bar can be rapidly advanced to the cutting position or rapidly retracted after cutting and, further, the drilling tool is designed to prevent blow out of the boring bar when cutting pipes under pressure.

摘要： The present invention provides a device for tapping a pipeline submerged in water and while in service. The present device comprises pipe saddle means adapted to fit around and clamp over a given submerged pipeline to be tapped. The pipe saddle is adapted for injection of an epoxy resin therein to form a fluid tight seal between the pipe and the saddle. The saddle is also provided with a side outlet to which full flow through valve means is operably connected. Pipe tapping or drilling means are in turn provided for connection to the valve means whereby when said valve means is in a fully open position, the drilling head of the drilling means can be inserted through the valve and side outlet of the pipe saddle into contact with the pipe to be tapped. The tapping means further comprises a packing assembly for sealing off the tapping sub-assembly upon drilling through the pipe, as well as means for controlling the exact depth of drilling.

摘要： A method for opening a flow-way in a main when a main is to be connected to a secondary main or service line. In opening the flow-way in the main, a perforator or tapping tool is utilized, which will progressively form the hole or aperture in the main by upsetting the material of the main outwardly of the same into the through bore of a fitting attached to the main, the upset material acting as a mechanical fastening means for increasing the resistance of a fitting to twist about the axis or center line of the main.

摘要： The disclosure herein describes a drilling apparatus for tapping fluid-conveying pipes under high internal pressure and temperature. The apparatus consists of a tubular housing in which a piston supporting a core drill shaft is axially displaceable. The shaft is rotated by an air driven motor and the piston is moved under the action of a working fluid fed into the housing through appropriate hydraulic conduits. The fluid is maintained under a predetermined positive pressure to provide the core drill with a constant cutting feed. In one preferred form of the invention, the air driven motor is enclosed in the piston.
