  • Patent number: 8512335
    Abstract: A high frequency alternating current medical device and method of using such is disclosed. High frequency alternating current medical device comprises a power source, an electric field generator, a self-limiting conductive material electrical component, at least one probe or needle-type projection, and at least two conductive segments located on probe or needle-type projection. At least two conductive segments are electrically connected to electric field generator so that an electric field is created between conductive segments, which induces an electrical current, which generates heat, and causes a certain desired precise cell injury. Self-limiting conductive material electrical component allows such precise cell injury because it limits electrical current through target tissue. Invention may be used in medical, dental, or veterinary applications. Exemplary embodiments include cosmetic applications, treatment of wrinkles, remodeling of subcutaneous tissue, treatment of muscle spasms, and others.

  • Patent number: 8440864
    Abstract: In a process for producing sec-butylbenzene, a C4 olefinic hydrocarbon feedstock comprising isobutene and at least one n-butene is contacted with methanol and/or water in the presence of an acid catalyst to selectively oxygenate isobutene to produce an effluent stream rich in n-butene and containing less isobutene than the feedstock. The effluent stream is then contacted with benzene under alkylation conditions and in the presence of an alkylation catalyst to produce alkylation stream comprising sec-butylbenzene.

  • Patent number: 8359496
    Abstract: The present disclosure relates to techniques for potentially increasing the reliability and/or stability of systems having virtual machines that support multiple modes of execution. For example, as described herein, a virtual machine partitions a plurality of program instructions into a plurality of traces for execution by a virtual machine operating on a computing device, wherein the virtual machine has first and second modes of execution, and wherein each of the plurality of traces comprises one or more of the plurality of program instructions. The virtual machine applies the second mode of execution to a first trace in the plurality of traces and determines an error condition that is caused by the application of the second mode of execution to the first trace. After determining the error condition, the virtual machine applies the first mode of execution to the first trace to recover the virtual machine from the error condition.

  • Publication number: 20120271076
    Abstract: A process is described for producing a catalyst composition comprising an iridium component dispersed on a support. In the process, silica-containing support is treated with an iridium compound and an organic compound comprising an amino group to form an organic iridium complex on the support. The treated support is then heated in an oxidizing atmosphere at a temperature of about 325° C. to about 475° C. to partially decompose the organic metal complex on the support. The treated support is then heated in a reducing atmosphere at a temperature of about 350° C. to about 500° C. to convert the partially decomposed organic iridium complex into the desired iridium component.
