  • Publication number: 20180141791
    Abstract: A hydraulic jack system for lifting a load is disclosed comprising a hydraulic cylinder having a hydraulic piston for displacing loads and a locking ring for locking the hydraulic cylinder in place when pressure is removed from the hydraulic cylinder. The jack system also has a gear operatively connected to the locking ring for displacement of the locking ring and a top plate connected to the hydraulic piston for receiving the load. A bottom plate connected to the hydraulic cylinder to provide support to the hydraulic cylinder is also disclosed and, securing means for attaching the bottom plate to the hydraulic cylinder wherein the securing means allow for movement of the bottom plate when the hydraulic jack system is lifting a load.

  • Patent number: 7555179
    Abstract: An optical microresonator is formed as a microcylinder and a resonant waveguide on the microcylinder and having a plurality of spaced resonant elements such as circumferential ridges for optically coupling light from an optical source waveguide onto the microcylinder. The resonant elements have a spacing, height and angle to impart a desire polarization and bring in the polarization states into degenerancy. A coating could also be formed over the resonant waveguide and operative with the resonant waveguide and of a refractive index to bring any polarization states into degenerancy.

  • Patent number: 7415178
    Abstract: An optical microresonator includes microcylinder and spiral resonant waveguide formed on the microcylinder that optically couples light from an optical source waveguide to the microcylinder and slows light propagating along the microcylinder. A coupling element, for example, a diffraction grating can be operative with the resonant waveguide structure and configured to meet a desired phase matching A second microcylinder having a spiral resonant waveguide formed thereon can be positioned adjacent to the spiral resonant waveguide formed on the first microcylinder for coupling therewith. The spiral resonant waveguides on first and second microcylinders can be configured for slowing light propagating along the microcylinder.

  • Patent number: 7224866
    Abstract: An apparatus and method forms an optical microresonator and includes spaced high precision ferrules through which an optical fiber passes. A ferrule can be rotatable and movable longitudinally in an axial direction. A clamp engages a ferrule and is operable to secure the optical fiber within a fiber guide of a ferrule such that the optical fiber can be rotated and translated longitudinally in a precision manner for writing a pattern on the optical fiber and forming a resonant waveguide.

  • Patent number: 7187827
    Abstract: A coupled waveguide optical microresonator is formed from a plurality of microcylinders coupled together. Each microcylinder includes a resonant waveguide. At least one of the microcylinders is adapted to be positioned adjacent an optical source waveguide for optically coupling light from an optical source waveguide onto the resonant waveguide on the microcylinder. The microcylinders are coupled together at the resonant waveguides, which are mutually coupled. Any coupled fields add coherently with each other.
