Abstract: Concepts presented herein relate to an interface module that can be electrically coupled to an electrical stimulation generator, a radio frequency generator and an instrument. A selection module is coupled to the interface module and operates in a first mode to deliver electrical stimulation signals from the electrical stimulation generator to the instrument and in a second mode to deliver radio frequency signals from the radio frequency generator to the instrument.

Abstract: In the specification and drawings, an apparatus for conducting hot work is described and shown with an enclosure; a hot work apparatus operable within the enclosure; and a detector located exterior of the enclosure, the detector being in detecting communication with the interior of the enclosure, such that the detector detects the presence of a condition within the enclosure. A method of conducting hot work is also described and shown.

Abstract: The present invention is related to water-based inks for making colored hydrogel contact lenses, in particular, colored HEMA-based hydrogel contact lenses. The ink of the invention comprises at least one colorant, water, and a water-soluble and actinically-curable binder polymer which is a vinyl group-terminated polyurethane polymer, a vinyl group-terminated polyurea binder polymer, or a mixture thereof. Also, the ink of the invention is characterized by having a viscosity greater than 50 centipoise (cps), a prolonged stability, and a good adhesion to a HEMA-based hydrogel contact lens. The ink of the invention preferably further has a good compatibility with a HEMA-based hydrogel material, and/or good transferability from a mold to a HEMA-based hydrogel contact lens made in the mold. The present invention is also related to a method for making colored hydrogel contact lenses using an ink of the invention.

Abstract: A method to apply a high performance overlay to a metal substrate of a rock bit to render the substrate surfaces of the rock bit more resistant to erosion, corrosion and substrate cracking while performing in an earthen formation is described. The method comprises the steps of bombarding the surfaces with a thermal spray of entrained fine particles of a cermet based composition at a velocity in excess of 3,000 ft/per sec. The resultant coating of the cermet based composition has a tensile bond strength in excess of 20,000 psi that results in an increase of the strain to fracture of the rock bit surface. The hard overlay has a resistance to severe service environments of high strain and shock tolerance as well as a higher load carrying capacity.
