  • Patent number: 11400508
    Abstract: Techniques for implementing and/or operating a system that includes a pipe fitting to be secured to a pipe segment, in which the pipe fitting includes a grab ring having a grab notch and a fitting jacket to be conformally deformed around tubing of the pipe segment to facilitate securing the pipe fitting to the pipe segment. The system includes a swage machine, which includes a grab plate having a grab tab that matingly interlocks with the grab notch to facilitate securing the pipe fitting to the swage machine, a die plate including a die that opens away from the grab plate, and a swaging actuator secured to the die plate. The swage machine operates the swaging actuator to move the die plate over the fitting jacket in an outwardly axial direction away from the grab plate to facilitate conformally deforming the fitting jacket around the tubing of the pipe segment.

  • Publication number: 20210091775
    Abstract: An example frequency converter includes a drift canceling loop with a balanced delay and a linear signal path (e.g., linear with respect to frequency scaling, amplitude modulation, and/or phase modulation). One side of the drift canceling loop includes a fixed delay, and the opposite side includes an adjustable, complementary delay. The adjustable, complementary delay facilitates precision matching of the signal delays on each side of the loop over a range of frequencies, which results in a significant improvement in noise cancelation, particularly at large offsets to the carrier, while permitting the use of a higher noise, but very fast tuning course scale oscillator. The linear signal path from the signal generator to an RF output facilitates modulation of the signal by the signal generator. A modular format is an advantageous embodiment of the invention that includes the removal of the frequency synthesizer's low phase noise reference into a separate module.

  • Patent number: 10822976
    Abstract: A nozzle assembly includes a first nozzle cavity, a second nozzle cavity, a rib positioned between the nozzle cavities, a rib cap positioned on the rib, a first cavity insert, and a second cavity insert. The rib cap is wider than the rib, such that the rib cap extends outwardly into those portions of the nozzle cavities immediately adjacent the rib. The first cavity insert and the second cavity insert include a longitudinal surface offset from the rib. The offset surfaces include rib cap-interface surfaces that are joined to the rib cap. A method of modifying the nozzle assembly is achieved by installing a rib cap having a width greater than that of the rib and by installing modified cavity inserts having a surface offset from the rib, and by joining rib cap-interface surfaces of the modified cavity inserts to the rib cap.
