Abstract: The present invention is for a downhole tool having a perforator gun portion disposed within a housing of the downhole tool for perforating an oil and gas formation. The downhole tool also includes a bypass passageway for directing fluid past the perforator gun portion in the downhole tool to permit fluid flowing into the downhole tool to flow out of the downhole tool to facilitate an oil and gas operation. Furthermore, the downhole tool is used in a method of performing the oil and gas operation in a wellbore by pumping fluid through the downhole tool.

Abstract: A prefabricated window system includes a main frame which is fabricated from thermoplastic elements having substantially the same cross-sectional configuration. Windows and a screen are slideably mounted in the main frame. A thermoplastic sill is snap-connected to the bottom portion of the frame and a decorative cover is snap-connected to the top portion. Stop elements, having the same cross-sectional configuration as the cover element, are snap-connected to the side portions of the frame in order to prevent the windows from being raised or lowered too far. The windows can be pivoted for cleaning, and the frame includes portions which overlap the outer peripheries of the windows to prevent them from inadvertently being rotated outward. These portions also reduce air incursion. A latch is mounted on one window and a keeper which cooperates with the latch is mounted on the other, the keeper being firmly mounted in the window sill by upwardly extending screws.

Abstract: A prefabricated window system includes a rectangular main frame having a top frame portion, a bottom frame portion, and two side frame portions. The frame portions are extruded thermoplastic elements having substantially the same cross-sectional configuration. The frame portions include first and second channels which, in the side frame portions, serve to guide windows. The frame portions also provide a third channel which, in the side frame portions, serve to guide a screen member. The window system also includes a sill which is connected to the bottom frame portion. The sill includes an extruded thermoplastic element which is snap-connected to the bottom frame portion and which is braced with respect to the bottom frame portion. The sill covers the window channels of the bottom frame portion, and additionally has an overhang portion which covers the screen channel of the bottom frame element to keep debris out.

Abstract: A prefabricated slider window system includes a main frame made from extruded thermoplastic members. Windows are mounted in the main frame for horizontal sliding movement. The main frame includes a bottom frame portion having channels for guiding the bottom sides of the windows, and a top frame portion having channels for guiding the top sides of the windows. The channels are deeper in the top frame portion than in the bottom frame portion to permit the windows to be raised out of the channels in the bottom frame portion. The raised windows can then be removed from the main frame so that the outdoor sides of the windows can be cleaned.
