  • Patent number: 5107578
    Abstract: A novel chair rung repair kit and method to repair a broken chair rung is described. Normally, after a period of time, chair rungs tend to dry out, especially those made from wood. By drilling a small, tapered hole in the longitudinal end of the broken rung, and by inserting a small, tapered and barbed element therein, the rung can be expanded to its normal size and thus repair can be accomplished quickly and easily. The repair is then permanent.

  • Patent number: 4994113
    Abstract: A mixture of waste, essentially cellulosic material and a fire proofing solution can be used to make building materials with exceptional qualities. These qualities include fire proofing, vermin proofing, water proofing and excellent insulative values, for example. Additionally, this process represents an excellent method for recycle of these waste materials. A sheetrock-like or wall-board material can be made therefrom, one which can be nailed, screwed, drilled and fastened without causing serious damage to the surface or the element itself.

  • Patent number: 4935058
    Abstract: A novel, metal protective solution is described. This solution of two parts, the first part being a mixture of one aqueous potassium silicate and two aqueous sodium silicate solutions and the second part comprising approximately equal amounts of acetic acid, zinc oxide, copper sulfate, clay and sodium bicarbonate, is stable, relatively inert and has a long shelf-life. It may be applied to metal surfaces to prevent corrosion and rust from forming thereon.

  • Patent number: 4886548
    Abstract: A novel and stable coating solution for fireproofing building materials is described. This solution is easy to apply and will reduce the propensity of burnable materials to sustain combustion. Alternatively, the solution may be used as a part of the solution used to cast paper on the surface of paper containing wallboard and the like. The solution finds particular use in fireproofing of wall boards and the like.
