Abstract: The embodiments of Fan Fold Support employ a foam sheet with folds and apertures formed by the foam sheet. The apertures are formed by the foam sheet at alternating folds so that every other fold has an aperture. The final end shape is formed by folding in an accordion-like manner the folds and secured with a compression band. When folded the foam sheet folds are oriented at the top of the folded structure and the apertures are located at the bottom of the folded structure. The sheet may be of various geometry so as to accommodate a variety of final folded end shapes such as a block form, an oval shape, a square, a cylindrical, a cone, a cubic, hexagon, a pentagon, and other multi-sided structures. Objects to be supported are then placed between the folds formed by the foam sheet in the Fan Fold Support.

Abstract: An improved outlet valve assembly (12) is provided which is especially adapted for use with an intermediate bulk container (10) having bottom wall drain outlet (20) and support legs (22). The assembly (12) has serially interconnected valves (28,30), namely an emergency ball valve (28) and a manually operable valve (30), with endmost elbow coupler (26) and outlet (32). Tle assembly (12) is of compact design and is dimensioned to permit attachment to container (10) with the entirety of assembly (12) elevated above the bottom of support legs (22). The emergency ball (28) valve includes as spring-loaded operator (58) equipped with a temperature responsive fusible link (86). In the event of a fire adjacent container (10), the link (86) severs, allowing operator (58) to quickly close valve (28).

Abstract: A foldable container comprises a box including a floor and sidewalls attached to one another to present a chamber. The box further includes foldable panels that shift from a retracted position within the chamber to an upright extended position. The extended panels serve to expand the chamber for containing a liquid or solid bulk material. The extended panels are interconnected by joints that resist tampering and that are tamper-evident. The container further includes a retaining assembly for securely holding the material in the chamber and a lid for covering the chamber. The lid cooperates with the panels to resist tampering and to be tamper-evident. The container also includes stanchions for selectively stacking at least two containers when the containers are storing the bulk material.

Abstract: An improved shaft sealing assembly (18) for use with an elongated, axially rotatable shaft (14) typically forming a part of a blender (10) or similar device is provided, which permits rapid, easy seal repair without the need for complete breakdown of the blender (10). The assembly (18) includes a tubular sleeve adapted to be disposed about the shaft (14) at the region of a shaft/blender wall interface, with an annular sealing body (42) disposed about the sleeve (40) in a sealing position and supporting a seal (66) which engages the sleeve (40) at a first sealing location (66a) thereon. A lock device (48) operably to maintain the sealing body (42) in its sealing position is provided, and the sleeve (40) is selectively movable relative to shaft (14) and sealing body (42) so as to change the sealing location from the first location (66a) to a second, different sealing location (66b). The sleeve 40 can also be easily replaced if desired.

Abstract: A latch dog assembly for latching and unlatching a storage bin door includes a latch dog member having a base portion, an end wall portion, and a cylindrical wear block member which extends outwardly from an opening on the inner wall of the end wall member so as to allow a latching cam to properly secure the bin door while avoiding undesired metal to metal contact. In one embodiment of the invention, a projection extends outwardly from the latch dog member base portion upper surface so as to assist in retaining the wear block member within the opening in the inner face of the end wall portion.

Abstract: A fire extinguisher nozzle including a horn defining a discharge chamber and a discharge member mounted to the horn. The discharge member includes an entry passageway for receiving fire extinguishant from a source therefor. The entry passageway communicates with a plurality of transverse discharge passageways and a central, axial passageway for delivering the fire extinguishant into the discharge chamber of the horn. Improved throw characteristics for fire extinguishants are achieved.

Abstract: A valve guard for the protection of a bottom discharge valve on a portable tank is formed of a single elongated piece of metal and has a central stabilizing ridge which extends outwardly from the front wall of the valve guard and which runs nearly the full length of the valve guard. The valve guard has a deflector arm at each end which extends out from the valve guard body at an angle and which cooperates with the tank legs to deflect any misguided forklifts or other machinery away from the valve on the underside of the tank. The central ridge is rounded and can have a width from approximately one-fourth to approximately one-third the width of the front wall of the valve guard. The valve guard is lightweight, durable, and can be formed quickly and economically through a rapid sequence of metal stamping operations.

Abstract: An improved tank configuration includes a die employed to stamp a formed member. The formed member may be used as the bottom head for a portable liquid container, and is constructed so that all welding is eliminated in the corner portions of the container. A trim machine is employed to remove uneven edges from the formed part. The invention is particularly useful in constructing sloped bottom tanks of increased depth. By the present invention, a stamped configuration is provided in which a draw formed tank bottom is formed so as to allow complete and full drainage of the tank bottom. The bottom head is finish trimmed to exact dimensions so as to facilitate assembly to the shell of the tank.

Abstract: A flat bottom tank provides for complete drainage of liquid contents through sloped drainage in the bottom head. The bottom head has a raised center portion which is pyramidal shaped in one embodiment. The sides of the bottom head are broken upwardly to form smooth, rounded wall surfaces. The center portion and the side walls slope downwardly towards one another to form a line of flow extending around the perimeter of the center portion. The line of flow slopes downwardly from a first corner of the bottom head to a second corner of the bottom head which is diagonally opposite the first corner. A drain outlet located adjacent the second corner allows for the drainage of liquid contents from the tank.

Abstract: A tumbler loader assembly is capable of moving a container to be tumbled from a conveyor loading area into a tumbler device using a feed cart while maintaining a low cart profile. The feed cart is capable of moving the container on conveyor rollers along the feed cart as well as having the capability for movement along a guide rail from a first position where the container is loaded onto the feed cart to a second position interior of the tumbler. The tumbler device has raising and lowering capability for interengaging the feed cart as well as for positioning the container for proper tumbling. Upon loading of the container onto the feed cart, the feed cart moves along the guide rail into the tumbler. The tumbler lowers to interengage the feed cart. The feed cart then transfers the container into the tumbler and the tumbler raises to allow the feed cart to return to its starting position.

Abstract: An improved tank bottom configuration formed from a flat metal plate of square or rectangular shape is disclosed. The plate is sheared to provide two adjacent sides which are tapered along their lengths and a notch is cut in each corner portion. By the use of stop and die members, the plate member is deformed to provide a bottom wall portion which slopes downwardly toward one corner and upwardly extending side wall portions which extend around the periphery of the bottom wall portion. A drain opening and a crease are formed in the bottom wall portion, with the crease being aligned with and spaced from the drain opening.
