Abstract: A slurry recycling apparatus having a first filter, a dirty side storage tank, slurry pump, second filter, clean side storage tank and slurry outlet, in which used slurry from an edge notch polishing apparatus is delivered to the first screen filter, transported to the dirty side slurry storage tank, pumped from the dirty side slurry storage tank through a second filter that filters out small particulate matter from the slurry and allows the slurry to pass to the clean side slurry storage tank, and finally to the edge notch polishing apparatus as needed. Slurry which is not immediately taken from the clean side slurry storage tank is continuously recycled through the second filter by overflowing from the clean side to the dirty side slurry storage tank where it is there pumped through the second filter back into the clean side slurry storage tank.

Abstract: In spinner tongs, a so-called spinner (30), incorporated in an iron roughneck and thus serving to rotate a drill pipe during connection thereof to a drill string or during division of the drill string into individual pipes, the aim has been to reduce damage on the threaded connections (the pin-and-box joints) in the screwing/unscrewing operations. This is realised in an operation for the simultaneous centering and rotating of the drill pipe. Four spinner rollers (42) known in themselves, which are brought to bear on the drill pipe when surrounding it, are mounted according to the invention, preferably in pairs, at the outer ends of driven clamping arms (46), by bogies (50). At their opposite outer ends the clamping arms (46) are pivotally supported on a fixed frame part/structure (56) and are jointed to each other by means of a piston and cylinder (48) driven by pressure fluid and arranged to carry the clamping arms (46) towards and away from each other.

Abstract: A multi-piece socket system having a large internal cavity to allow a protrusion of a long rod or other workpiece to extend into the socket. The socket section has at least two pieces: a drive adaptor and a socket. Optionally, one or more extension collars may also be used. When assembled, the socket, extension collar(s) if used, and drive adaptor form a long tubular body into which a rod or other central member may enter while the nut is being driven onto the rod. The drive adaptor, extension collars, and sockets preferably attach together using a plurality of interlocking teeth on the ends of each member. For further stability, a spring biased pin extends from the wall of one member and through a hole in the wall of the mating member. Additional attachments, such as a threaded rod and drill chuck, may also be used.

Abstract: A portable hand-held screw driving tool is provided for use with collated strips of screws. A collated strip of screws enters from the “bottom” area of the tool and runs through a fixed guide along a front area of the tool's handle, and then to a movable slide body having a rotatable sprocket that receives the collated strip, and indexes the strip so a screw can be driven by the tool. Between the slide body and the fixed guide is a flexible strap with a bracket that places tension on the collated screw strip, which prevents the flexible collated strip from becoming substantially misaligned (e.g., bunching, sagging, or becoming tangled) in the area between the fixed guide and the slide body. The collated strip is kept sufficiently taut, regardless of the orientation of the screw driving tool with respect to the ground.

Abstract: A guidance channel radiating from each side of clip holding chamber centered on a flat plate. A prying tool slideably and rotatably held within each guidance channel by a spring strip. A split ring held snugly within the holding chamber. The tool tips are forced between the split ring coils, which are separated further by simultaneous rotation of the prying tool handles 90-degrees in opposite clock directions. A pellet placed inside folded bag material forms a bump. The material with bump is placed between the separated coils into the split ring interior. Reverse 90-degree handle rotation partly closes the coils around the bump. Withdrawing the prying tools completely allows the coils to fully close, capturing the pellet-containing material. Tool stops prevent the tool tips from entering the split ring interior too far into or away from the clip holding chamber. Suspension of the tool and bags facilitates production.
