Patent number: 8920633Abstract: High energy (e.g., ultrasonic) mixing of a liquid hydrocarbon feedstock and reactants comprised of an oxidation source, catalyst and acid yields a diesel fuel product or additive having substantially increased cetane number. Ultrasonic mixing creates cavitation, which involves the formation and violent collapse of micron-sized bubbles, which greatly increases the reactivity of the reactants. This, in turn, substantially increases the cetane number compared to reactions carried out using conventional mixing processes, such as simple mechanical stirring. Alternatively, an aqueous mixture comprising water and acid can be pretreated with an oxidation source such as ozone and subjected to ultrasonic cavitation prior to reacting the pretreated mixture with a liquid hydrocarbon feedstock.Type: GrantFiled: September 8, 2010Date of Patent: December 30, 2014Assignee: Cetamax Ventures Ltd.Inventors: Kin Meng Chan, Kamalul Arifin Yusof, Shahrul Niza Bin Abdul Rahim, Md Asraff Bin Abdul Karim, Roger Kai Lott

Patent number: 6102379Abstract: A metal spring with embedded constrained layer damping provides effective damping of a supported load. A continuous load bearing tube is provided with an inner diameter and an outer diameter with a plurality of constraining layer tube sections concentric with the load bearing tube and spaced along the load bearing tube. A damping layer of a viscoelastic material contacts facing surfaces of the continuous load bearing tube and the constraining layer tube sections so that shear strains are induced in the viscoelastic material from relative rotation of the load bearing tube and the constraining layer sections to provide damping of an applied load. In one embodiment, the constraining layer tube sections and damping are within the load bearing continuous tube and the continuous tube is sealed at each end to permit use of the spring in a vacuum environment.Type: GrantFiled: November 17, 1997Date of Patent: August 15, 2000Assignee: Hytec, Inc.Inventors: Eric R. Ponslet, William O. Miller
