Abstract: Card cages for mounting an array of electronic modules are provided for. The card cage comprises a plurality of generally rectangular shaped panels, including a top panel, a bottom panel, a back panel, and two side panels. The panels are adapted for assembly into a generally right-rectangular prism shaped frame having a closed back and an open front and defining one or more module mounting areas. The card cage also comprises guides adapted to slidably receive one or more electronic modules having electrical connectors. The guides are provided on at least one panel defining each mounting area. The back panel has electrical connectors adapted to engage the electrical connectors of the electronic modules. The top, bottom, and side panels are interlockable. Those interlockable panels are fabricated from a single sheet of metal and have a plurality of integral interlocking members. The interlocking members collectively constitute a plurality of associated pairs of tongues and openings.

Abstract: An improved mounting for an extension tube is disclosed for use with a fluid sprinkling apparatus. The fluid sprinkling apparatus has an input orifice communicating with a liquid internal a pressurized container for spraying the liquid through the extension tube. An actuator controls the flow of the liquid from the input orifice to a terminal orifice. A bore is defined in the fluid sprinkling apparatus extending from an outer wall and terminating in a inner wall. The terminal orifice is disposed within the inner wall and axially aligned with the bore. The bore has a plurality of shoulders spaced along the bore from the outer wall to the inner wall for respectively defining a plurality of bore portions. The plurality of bore portions have progressively decreasing diameters from the outer wall to the inner wall for enabling the extension tube to be inserted into the bore and be frictionally retained by at least one of the bore portions.
