  • Patent number: 10804064
    Abstract: Technology is described for a magnetic lift device for an x-ray tube. In one example, an anode assembly includes an anode, a bearing assembly, a ferromagnetic shaft, and a lift electromagnet. The anode is configured to receive electrons emitted by a cathode. The bearing assembly is configured to stabilize the anode during a rotation of the anode. The ferromagnetic shaft is coupled to the anode and has an axis of rotation that is substantially collinear with an axis of rotation of the anode. The lift electromagnet is configured to apply a magnetic force to the ferromagnetic shaft in a radial direction.

  • Publication number: 20160220536
    Abstract: Treatment of autoimmune and/or inflammatory diseases associated with overexpression of Toll-like receptor 3 (TLR3) as well as Toll-like receptor 4 (TLR4) and/or TLR3/TLR4 signaling in nonimmune cells, monocytes, macrophages, and/or dendritic cells in association with related pathologies. The use of phenylmethimazoles, methimazole derivatives, and tautomeric cyclic thiones for the treatment of autoimmune and inflammatory diseases associated with TLR3 as well as TLR4 and/or TLR3/TLR4 cellular signaling in association with related pathologies is disclosed. Methods of treating a subject having a disease or condition associated with abnormal TLR-3 as well as TLR-4 and/or TLR3/TLR4 cellular signaling in association with related pathologies are also disclosed. The present disclosure also relates to the treatment of autoimmune-inflammatory pathologies and chemokine and cytokine-mediated diseases associated with TLR overexpression and signaling.

  • Patent number: 8852521
    Abstract: The present disclosure is drawn to methods and systems for producing solutions containing ultrafine metal particles. The method for producing ultrafine metal particles in an aqueous medium includes providing a reaction chamber having a transition metal anode and a transition metal cathode disposed therein. The reaction chamber can also contain an aqueous medium. An anode and cathode are associated at a distance with respect to one another such that when activated by a power source, a discharge arc occurs between the anode and cathode within the aqueous medium. Activation of a power source causes the discharge arc to occur between the anode and the cathode, thereby generating ultrafine metal particles suspended within the aqueous medium.

  • Patent number: 7198081
    Abstract: A portably log splitter is provided. The log splitter comprises a base having a pair of one-piece side members, and a support member to which the one-piece side members are attached. The support member and the one-piece side members form a seat that is adapted to receive a log. The log splitter also includes a splitting wedge that is attached to the support member and a contact member that is configured to translate in a reciprocal manner adjacent to the support member in order to move the log. The log splitter also includes a control assembly operated by a switch to actuate the contact member in the reciprocal manner.

  • Patent number: 7124525
    Abstract: A system for mounting a flexible sheeting material to a substrate is comprised of a number of frame sections including an elongate support member secured to the substrate and an elongate connector member secured to an end portion of the flexible sheeting material, with the support member and the connector member including interlocking anchor elements capable of forming a releasable interconnection therebetweeen. The support member and the connector member each include a tool engaging portion defining oppositely facing bearing surfaces. A tool is provided which includes a first engaging surface positioned in abutment against one of the bearing surfaces, and a second engaging surface positioned in abutment against the opposite bearing surface. Displacement of the engaging surfaces along the bearing surfaces tensions the flexible sheeting material to a taut state, with the interlocking anchor ribs forming a releasable interconnection to maintain the flexible sheeting material in the taut state.
