Abstract: Bags for storing granular material are disclosed, the bags having an inner woven polymeric layer, an outer nonwoven polymeric layer, and an extruded polymer layer bonding the inner layer to the outer layer. Methods for forming the bags are also disclosed.

Abstract: A woven fabric protective covering to ensure long lasting and reliable product and also reliable and easy operation when installing the covering. The woven fabric comprises a sheet layer, a reinforcement layer and at least one film layer. A plurality of strip formed weft elements and warp elements are woven together to form the sheet fabric. The sheet fabric comprises at least two different types of weaves, a basic weave for a main sheet fabric area having substantially equal number of orthogonally woven weft elements and warp elements, and a relief weave to form a fastening region where the number of warp elements per width unit is reduced when compared to the number of weft elements. The reinforcement layer is a woven band and is laminated on at least one side of the sheet layer. The reinforcement layer comprises openings for fastening the product when in use. At least one film layer is laminated on the sheet layer.

Abstract: A spring loaded detent having a particularly designed, angled head normally utilized in holding and releasably locking two elements such as tubular members together. The angled head assists in the of entrance of the detent into the held member and facilitates the ease of moving the detent against spring force, from its locking position for separation of the members. By increasing the ease of detent entrance into the member to be joined, a positive, yet easily releasable lock is provided between the members. Similarly, the shaping of the head of the detent reduces the pressure required to overcome the locking spring force and allows separation of the members with particular ease.

Abstract: A connector system for tubing or piping which provides a male/female combination for the joining of tubes, pipes or the like for rapidly assembling and disassembling various structures such as temporary canopies, tents or the like. The system provides a male member having a spring loaded detent on the interior thereof and extending outwardly thereof with the female member, sized to be received over the male member, having a detent passing aperture through at least one side thereof for effectively and rapidly allowing joinder of units. To erect a supporting structure the connectors are provided at corners or within straight sections to join and extend straight sections. The straight sections are of selected lengths and each end thereof constitutes either a male or female connector for interconnect of the joining elements which may be straight or which may consist of a plurality of joining elements arranged angularly with respect to one another to achieve a corner.
