Abstract: An apparatus for holding a fumigant container has a sleeve with an interior volume, a first fastener affixed to the sleeve adjacent an end of the sleeve and extending outwardly therefrom, and a second fastener affixed to the sleeve adjacent the opposite end thereof. The first and second fasteners are suitable for removably affixing to at least an exterior surface, such as a pair of rails of a hopper car. Each of the fasteners includes a clip and a strap affixed to the clip. The clip includes a body formed of a polymeric material and having an aperture formed therethrough and an arm having one end integrally formed at the body and extending into the aperture such that the arm is flexible in relation of the body. The sleeve has at least one surface formed of a gas-permeable material. One end of the sleeve is open so as to allow for the introduction of a fumigant container into the interior of the sleeve.

Abstract: A shade structure having a suspended mast with a tubular body non-removably secured between at least two suspended mast support segments forming a suspended engagement. The shade structure has at least a first flange plate connecting a first mast transition segment to a first cantilever rafter and a second flange plate connecting a second mast transition segment to a second cantilever rafter. At least one column extension assembly simultaneously supports the cantilever rafters and connects each cantilever rafter to a column. A fabric canopy is disposed over and around the suspended mast and over the suspended mast support segments and cantilever rafters. Means to engage the fabric canopy is used with each cantilever rafter on a second cantilever rafter end and tensioning means secured to at least one of the cantilever rafter or the suspended mast is used for tensioning the fabric canopy.

Abstract: A fabric covered rigid frame structure having at least three elongate rafters; at least one column supporting the rafters; a fabric cover; a cord system or a web system encircling the fabric cover; and at least one tensioner formed in an end of at least one elongate rafter, wherein the tensioner includes an opening formed in an end of the elongate rafter along the axis of the rafter; a first fitting disposed between the opening and an end of the elongate rafter; a rod disposed in the elongate rafter along an axis of the rafter through the first fitting, wherein the rod comprises threads that are exposed to at least a portion of the opening; means for engaging the rod through the first fitting; and a sliding block with hook disposed on the threads of the rod interior of the elongate rafter wherein the hook engages the fabric cover.

Abstract: An anchoring method of fabric panels for flood control and water control, wherein the anchoring method comprises the steps of: attaching a plurality of anchors. Each anchor has a base, a first wall and a second wall disposed on opposite ends of the base, a chamber, and arms attached to the walls projecting away from the walls. An extension is attached to the first arm, wherein the extension projects over the chamber, then a deformable tube goes in the chamber near the first wall, a fabric panel attached to a mooring is then put in the chamber on top of the deformable tube, then inserting a chock into the chamber against the deformable tube, wherein the deformable tube is compressed, then inserting a key into the chamber between the chock and the second wall, wherein the chock engages the key and the deformable tube is uncompressed.

Abstract: An apparatus, a windscreen, and method for securing a structure against damage from high winds, wherein the windscreen is engagable with a track with slidable, adjustable connectors such as eyebolt connectors or fixed pin connectors that is secured to the eaves or sides of a house, and, with a coarse fabric such as the sheet attached to the track with strap like elements and connectors and anchoring device for securing the windscreen to the ground preventing damage to the structure.

Abstract: A moisture barrier seal for use on a hopper car hatch opening that does not need to be removed before vacuum unloading of the hopper car due to the use of a grained plastic such as vertically drawn or cast polyethylene which will rupture as soon as the seal is subjected to the pressure differential across the seal created by the application of vacuum to the hopper car. The moisture barrier layer when combined with a filter layer forms a combination moisture barrier and filter seal.

Abstract: A system for preventing contamination of particulate material in a railroad hopper car during transportation and unloading of the material from the car, comprising transporting the material in the railroad hopper car with a filter on each of the various inlet and outlet openings of the car, then upon reaching the point for unloading, applying a vacuum to draw the material out of the car through one spout with its filter removed, while leaving the filters in place on the other openings in the car to prevent contamination of the product from external sources during transportation and unloading. The preferred filter for the railroad car spouts has a frame, a conical filter bag, and a filter bag support ring for mounting on a spout on the car.
