Patent number: 11511460Abstract: Described are improved devices and processes for manufacturing concrete articles, including concrete pipe. In one embodiment, the invention provides an apparatus that has a first platform that is located beneath the floor of a manufacturing facility. The first platform includes a top surface and is configured to move bi-directionally along an axis. Two form bases can reside on the top surface of the first platform, each form base further including a form core that extends vertically from the first platform through respective holes in a second platform that resides above the first platform at an elevation even with or just above the floor's surface. The second platform is configured to move bi-directionally with the first platform between one of two cranes disposed on either side of a concrete mixer. A form is placed over the first core, which is then positioned under the outlet of an auger that receives concrete from the mixer.Type: GrantFiled: May 10, 2020Date of Patent: November 29, 2022Inventor: William M.

Patent number: 5881760Abstract: A metal or fiberglass, liquid storage tank having a top wall or an auxiliary flange plate which projects beyond the tank side and end walls to support the tank to a base vault and provide a support surface for a cover which is cast in place to the tank. The primary tank is mounted within an open-topped, reinforced cast concrete base which includes an internal thermal liner, liquid impermeable membrane, cover seals, tank cradles and support legs which define secondary and tertiary containment spaces. Sloped interior walls direct liquid and/or condensation to a sump region and a siphon assembly. The cover is integrally bonded to the tank and supports a number of projecting fill, vent, extraction, inspection, and monitor/siphon standpipes. Chamfered and interlocking surfaces are formed at the cover to base joint and lift eyes facilitate cover and tank removal, alignment, and tank inspection.Type: GrantFiled: September 23, 1996Date of Patent: March 16, 1999Inventor: William M.
