Patent number: 5092024Abstract: The method of fabricating fire resistant tank apparatus for transportation and for installation above-ground to receive and dispense a liquid hydrocarbon or hydrocarbons, includes providing a metallic tank assembly having lightweight wall means defining inner wall means, intermediate wall means and outer wall means, and spacing the wall means to form primary space between the intermediate wall means and the inner wall means, and secondary space between the intermediate wall means and the outer wall means; providing access porting to a tank interior defined by the assembly; a bottom wall defined by the assembly located to support the assembly at an installation site; and providing thermal barrier material in one of the first and second spaces to effectively define a shell about the tank interior. In addition, fire resistant material may be applied to the outer side or sides of the outer walls and hardened to define a relatively lightweight shell enclosing the tank assembly.Type: GrantFiled: April 11, 1991Date of Patent: March 3, 1992Assignee: LRS, Inc.Inventor: David C.

Patent number: 5082138Abstract: Fire resistant tank apparatus is adapted for transportation and for installation above-ground to receive and dispense a liquid hydrocarbon or hydrocarbons, or the like, and includes a metallic tank assembly having a lightweight, triple hulled, wall structure, defining inner, intermediate and outer walls which are spaced apart. Thermal barrier material is located in certain space between such walls, and in such manner that there is no direct heat conducting metallic path between such walls, as for example the intermediate and outer walls. In addition, fire resistant material may be applied to the outer side or sides of the outer walls and hardened to define a relatively lightweight shell enclosing the tank assembly. The structure resists severe heat invasion in the form of radiation, convection and conduction to maintain liquid hydrocarbon in the innermost tank isolated from such invasion. Also, the structure is bullet resistant.Type: GrantFiled: January 31, 1991Date of Patent: January 21, 1992Assignee: LRS, Inc.Inventor: David C. McGarvey

Patent number: 4948340Abstract: An above-ground storage system, especially for use with hazardous materials is disclosed. The system includes a first inner tank and a second outer tank. An air-operated diaphragm pump is used to fill the tank. In order to prevent overfilling of the tank and, therefore environmental contamination, a valve is installed in the air supply line to the air pump. The valve is operated by a float within the tank. When the float becomes submerged in liquid the valve is closed by an arm connected to the float.Type: GrantFiled: September 29, 1989Date of Patent: August 14, 1990Assignee: LRS, Inc.Inventors: Stuart G.
