  • Engine connecting rod for high performance applications and method of manufacture
    Publication number: 20080282838
    Abstract: An internal combustion engine connecting rod, having an embodiment defining a hollow beam member and a process of manufacture are disclosed. The improvement substantially reduces beam tensile and compressive stress levels through application of elliptical and convex segment profile beam sections, conserving reciprocating and rotating connecting rod weight required in high performance engine applications.

  • Method and composition for treating substrates
    Patent number: 6821631
    Abstract: A method of treating substrates, such as wood, including the steps of applying an alkali silicate solution to one or more substrates and applying an alkali borate solution with boric oxide (B2O3) content to the substrates. Substrates that have been treated using the present method include a borate-silicate polymer within the substrate. When the present substrates are wood, wood products, or green lumber, they may be used to build structures.

  • Rotary valving unit for an internal combustion engine
    Patent number: 4007725
    Abstract: An internal combustion engine wherein a rotary inlet gaseous mixture valve is provided and a separate rotary exhaust valve. The inlet valve and the exhaust valve are connected together through a drive means and are rotated at the same velocity and in precise timing with respect to the engine crankshaft. The exhaust valve includes a water cooling jacket thereabout. The inlet valve includes an individual gaseous mixture inlet passage for each combustion chamber.
