  • Storage tanks having secondary containment means
    Patent number: 4696186
    Abstract: A storage tank system especially useful for storing liquid gasoline in one aspect comprises a rigid inner tank encased by a flexible outer jacket with a leak detecting means associated with the closed space between the inner tank and jacket. In another aspect, an outer rigid tank contains a bladder within it together with leak detecting means between the tank and bladder. The system results in a storage facility which is less likely to lose its stored liquid to the environment due to a slow leak or a sudden large leak such as is possible with an earthquake.

  • Storage tanks having formed rigid jacket for secondary containment
    Patent number: 4653312
    Abstract: A method of making a jacketed storage tank comprises applying a separating agent over the storage tank, applying a layer of fibrous reinforcing material on the separating agent, and thereafter applying a resinous material.

  • Dual-inclined lifters for autogenous mills
    Patent number: 4515319
    Abstract: An autogenous mill for breaking up rocks comprises lifter bars and carriers. The lifter bars have angles of inclination so as to achieve the maximum efficiency of the mill with respect to lifting the rocks and causing them to fall. The angles of inclination of the carriers are also chosen so as to achieve the maximum efficiency of the carriers for lifting the crashed fines and causing them to exit the mill. The angles of inclination of the carriers is smaller than that of the lifter bars.
