  • Patent number: 6167388
    Abstract: The present invention relates to an automated system for specifying radiant tube heating systems. The automated specification system calculates the heat loss for a structure and adjusts the heat loss value according to deviations from standard radiant heating system installations. The specification system provides the user with burner and tube layout parameters in conjunction with an input menu for receiving the accessory equipment inputs of the radiant tube heating system. The specification system retrieves equipment specifications from a product database in response to user inputs and presents the user with a complete specification package for the specified radiant tube heating system.

  • Patent number: 4909845
    Abstract: Sprayable, pre-mixed, mine sealant compositions having enhanced strength properties and capable of retarding flame propagation and suppressing combustibility of substrate materials are disclosed in three general forms. In the first form, an alkaline silicate material such as sodium silicate is employed with perlite and a mineral acid in order to provide the above properties. In a second formulation, the first form is augmented by white pigments. In a third formulation, additional bulking materials e.g., cellulose are added to provide enhanced structural integrity and mine sealant qualities.
