Patent number: 8814110Abstract: A modular tank stand is lightweight and easily transportable, but also capable of supporting the weight of a large bulk storage container filled with flowable material. The modular tank stand includes a plurality of individual tank stand sections which are interconnectable with one another to form a larger support surface sized to receive the bulk storage container. The individual sections include integral, vertically disposed support walls that provide both vertical support for the weight of the bulk storage container and resistance to collapse under shear forces arising from movement of the container. The interconnecting individual sections may be disconnected from one another and reconfigured to fit in a smaller space, such as onto a pallet or within a shipping container, thereby facilitating storage of the disassembled modular tank stand.Type: GrantFiled: February 25, 2011Date of Patent: August 26, 2014Assignee: ROTO Engineering GmbH i.G.Inventors: David L. Crager, Douglas J. Murphy

Patent number: 8348090Abstract: A bulk storage container includes a tank with a “full drain” outlet, and a coupler attached to the outlet, in which the full drain outlet and coupler utilize a metal-on-metal threaded connection to create a fluid-tight seal therebetween. The polymer coupler includes a metal insert with internal threads, and the tank includes a metal insert with external threads corresponding to the internal threads of the coupler insert. The metal inserts are integrally molded within the walls of the tank and coupler, respectively. Advantageously, the threaded metal inserts provide a rigid structural connection between the tank and coupler that is highly durable and leak resistant. In addition to the threaded fluid-tight seal, a shoulder of the coupler abuts a corresponding face formed on the tank, with a gasket between the shoulder and face to provide a secondary seal.Type: GrantFiled: April 11, 2011Date of Patent: January 8, 2013Assignee: ROTO Engineering GmbHInventors: David L.
