  • Patent number: 10906104
    Abstract: Discussed herein are systems and methods of forming hardfacing coatings and films containing Q-carbon diamond particles for use in downhole drilling tooling and other tools where wear-resistant coating is desirable. The Q-carbon diamond-containing layers may be coated with matrix material and/or disposed in a matrix to form the coating, or the Q-carbon diamond layer may be formed directly from a diamond-like-carbon on a substrate.

  • Patent number: 10323347
    Abstract: A pallet drive system is provided that is operable for use on a sewing system. The pallet drive system has a pallet that is configured to hold a work-piece in position. A pair of alignment posts is coupled to the pallet. In exemplary aspects, each alignment post has a shape with surfaces extending in three dimensions along x, y and z axes. A corresponding pair of gripping fingers is coupled to a sewing machine, corresponding to each alignment post, that are moveable between an open position, allowing the alignment post to be positioned between the gripping fingers, and a closed position where the gripping fingers surround the alignment post. The gripping fingers define a cavity in the closed position to surround the alignment post in the x, y and z axes.

  • Publication number: 20160229514
    Abstract: Various systems, processes, and techniques may be used for producing a long modular window assembly for an aircraft. In particular implementations, a long modular window assembly may, among other things, include a frame, a motor, and a shade. The frame may include an inner shell and an outer shell. The inner shell may have a lens opening, and the outer shell an opening but no lens. The frame may have a frame interior. A lens may be provided for engagement to the lens opening of the inner shell. A multiplicity of brackets may attach the frame to engage the assembly to a side wall, typically curved, of an aircraft interior. An electric motor may engage the frame in the frame interior along the frame. A first shade is provided with a shade rail. The shade and the shade rail are dimensioned for receipt into the interior of the frame.

  • Patent number: 9193037
    Abstract: A method of making a polycrystalline diamond cutter element includes forming a blend, comprising a first particle size of polycrystalline diamond particles and a second particle size of polycrystalline diamond particles; forming a suspension of nanocrystalline diamond particles suspended in a solvent; and mixing the blend into the suspension to form a polycrystalline diamond mixture comprising nanocrystalline diamond coated polycrystalline diamond particles. The mixture is sintered with a substrate at high temperature and high pressure to form the polycrystalline diamond cutter element.

  • Patent number: 8875812
    Abstract: A polycrystalline diamond cutting (PDC) element of a drill bit of a downhole drilling tool is provided. The PDC element having a substrate, a diamond table and at least one pattern. The diamond table has an initial cutting edge along a periphery thereof. The pattern integrally formed within the diamond table. The pattern(s) defining at least one discontinuity about the diamond table that, in operation, selectively breaks away upon impact to create new cutting edges in the diamond table whereby a sharp cutting edge is continuously exposed to a material being cut.

  • Patent number: 8459815
    Abstract: A stage lighting lamp unit includes a processor for receiving control data from a remote console. Beam orientation data for the lamp unit is passed to the lamp in the form of the x, y and z co-ordinates of a point in space through which the beam is to pass. The processor divides the required lamp travel into a number of stages dependent on execution duration data sent with the position data, and calculates, for each stage, a new value for pan and tilt angles for the lamp. These values are passed to pan and tilt controlling co-processors which control servo-motors for pan and tilt operation. The lamp unit also incorporates a rotatable shutter for interrupting the lamp beam when required. The shutters of all the lamps in a system can be instructed from the remote console to open and close in synchronism, thereby providing a stroboscopic effect.
