A flexible container (10) has a base (12) that includes a bottom (20), side walls (22, 24, 26, 28) and an interior (30), the bottom defining a substantially flat planar surface when the container houses product and the container rests thereon, an upper panel portion (14), that is adapted to be received within the interior of the base portion and includes side panels that define a closure member (60, 62). The upper panel is constructed and arranged to define a substantially flat surface (72) when the closure member is closed and portions of the upper panel are folded over. The upper panel includes a portion that is sealed to the base portion. A pair of handles (16, 18) may be secured to the base portion. The flat top and flat bottom allow for vertical stacking of the filled containers. The container may be manufactured from a flat sheet of plastic material having a width substantially equal to a length of the base portion, by indexing the flat sheet in intervals equal to a width or more of the base portion; bonding handles at one end to the sheet; applying closure means to a free end of each of the pair of panels; and forming the flat sheet, panels and pair of handles into the flexible container.

A process employing a wet mixer having a vertical mixing chamber for forming a wet slurry of a cementitious powder and liquid. The vertical mixing chamber is designed to provide the required amount of mixing to provide thoroughly mixed, uniformly thin slurry within a mixing residence time that allows for adequate supply of slurry to ensure continuous operation of an associated cement panel production line. Gravity feed for supply of cementitious powder and water to the slurry mixing area of the chamber is also disclosed.

A process for producing fiber-reinforced structural cementitious panels made of at least one layer of fiber reinforced cementitious slurry, the process for each such layer of slurry including providing a moving web; depositing a first layer of individual, loose fibers upon the web; depositing a layer of settable slurry upon the deposited first layer of individual, loose fibers; depositing a second layer of individual, loose fibers upon the deposited layer of settable slurry; and actively embedding both layers of individual, loose fibers into the layer of slurry to distribute the fibers throughout the slurry.

A handheld wet slurry thickness gauge and method for its use. The thickness gauge includes a distance displacement measurement gauge, a skirt, a platen and support legs. The distance displacement measurement gauge includes a case, a vertical stem, and a vertical spindle. The stem extends from the case. The spindle is slidably supported to move in an axial direction within the stem. The case body has a display for indicating a linear displacement of the spindle. The skirt has a central through-hole for receiving the stem of the gauge and retaining the stem in an upright position. The measuring platen has a platen base and a platen shaft extending upwardly from the platen base and attached to the spindle. The support legs extend downwardly from the skirt. The platen is below the skirt.

A vibrating smoothing device or plate transverse to a direction of travel of deposited gypsum-cementitious slurry and embedded chopped fibers. The plate is used to smooth the top surface of the slurry panel as it exits a first fiber embedment station and a second slurry depositing station before passing through a second fiber embedment station of a structural cementitious panel production line to remove grooves and other non-uniform surface imperfections to have the slurry cover the embedded fibers. The plate is designed to float over the surface of the formed slurry without tearing or otherwise damaging the surface of the heavily fiber reinforced surface layers of the formed slurry before it sets. The vibrating plate is pivotally mounted on the web production line so it can float over the panel surface during use, but be raised off the line when not in use.

An electrical isolation connector subassembly for interconnecting adjacent tubular drill rods of a drilling system used in drilling bore holes in earth formations, the connector comprising an electrically insulative sleeve being sandwiched between two electrically isolated subassembly components, the sleeve providing an exterior gap between the edges of the spaced apart electrically isolated components, the exterior gap having a width of less than 50 cm.
