Abstract: Pile forming includes providing an anchor having a shaft with a major axis, a bit fixed at one end, and a stop releasably coupled to the shaft. A casing having a major axis, is co-axially aligned with the major axis of the shaft, between the bit and the stop. A centralizer maintains separation between the shaft and casing, creating a region therebetween. The anchor is placed in soil, ground or substrate, the shaft turned and pressure applied to advance the anchor, forcing material out of a region surrounding the shaft. The stop is decoupled from the shaft. The shaft is continually turned and pressure applied to further advance the anchor. A fluid grout is flowed into said region surrounding the shaft and into the region between shaft and the casing. The turning and application of pressure are stopped, and the fluid grout allowed to solidify.

Abstract: This invention is directed to an improved collapsible box for trash compactors and particularly aircraft trash compactors. The box is constructed from an integrally formed elongated main section having rectangularly shaped front, rear, and bottom panels and a pair of opposing side panels which are secured to continuous flanges hingedly connected to the vertical edges of the front and rear panels and to the horizontal edges of the bottom panel.At least one side panel is provided with a free-standing edge which is adapted to be seated in a guide or securing means or overhang within the compactor chamber which fixes the position of the side panel.A continuous medial fold line is provided at the middle of the front, rear, and bottom panels to facilitate the folding of the box into a collapsed state for storing. In the preferred embodiment, the front and rear panels are each provided with a pair of fold lines which extend from the lower edges of the panels to common points on the medial fold lines.

Abstract: A trash compactor and collapsible box for use therewith to handle waste material generated during flight of passenger-carrying aircraft. The trash compactor includes a housing formed with front and rear box chambers to receive first and second collapsible trash-receiving boxes. A front door is provided for the housing having a trash-receiving chute in its upper portion. The first box is initially disposed in the front box chamber. When it is filled, the front door is opened and the first box is pushed to the rear box chamber. The second box is then positioned within the front box chamber to receive trash, and the front door is shut. The collapsible boxes have a front wall disposed at the same elevation as the lower edge of the chute, while the tops of the side and rear walls are at a higher elevation than the top of the front wall to permit the boxes to receive a maximum amount of trash for their size. The bottom portion of the wall is of liquid-tight construction.
