  • Publication number: 20060137556
    Abstract: There is a process to make a combustion enhancement device for internal combustion engines. A base material is provided. A substance, emitting alpha and/or beta particles, is printed in a pattern wherein the pattern restricts disposition of the substance from designated cutting areas. The base material is cut in the designated cutting areas. Tabs, having edges cut in the designated cutting areas, are bent to approximately ninety degrees from the plane of the base material such that the substance faces inwardly.

  • Patent number: 7051719
    Abstract: A combustion enhancement device for internal combustion engines using alpha and/or beta particles to add ions to air intake thereby facilitating complete combustion. There is a base material with holes. Tabs form the walls of the holes or channels. On the base material and tabs there is a substance emitting alpha and/or beta particles. The substance also includes a bonding matrix material. The holes are configured to enhance exposure to high densities of alpha and/or beta particles. Engine performance purity and power may be significantly increased despite a possible impact of the device on air flux into the air intake.

  • Patent number: 6397651
    Abstract: A cutting edge is formed by build-up welding on a die of a die assembly made of a base material of an aluminum/copper-based zinc alloy. The cutting edge comprises an underlying layer and an overlying layer. The underlying layer is made of a copper alloy that can be welded to both a zinc alloy and a nickel alloy, and the overlying layer is made of a nickel alloy. The cutting edge is of high machinability, high durability, and high hardness.

  • Patent number: 4461466
    Abstract: A paper feeding device used for feeding stacked paper to an electrophotographic copying machine is provided with a lift for a stack of papers, which move the top sheet against a swingably supported feeding roller as the size of the stack decreases under use. Forwardly of the feeding roller in the direction of travel of the paper is a plate in frictional contact with the roller, the paper being thus fed forwardly to the copying machine through the nip between the roller and plate. This arrangement avoids the problem of a multifeed of the sheets. The feeding-out operation may be further improved by the provision of separating claws engaging the leading corners of the paper as it passes from the feeding roller. Raising of the lift is controlled by a detecting device actuated by position of the swingable support for the feeding roller.
