Patent number: 9477042Abstract: Techniques and systems suitable for performing low-loss fusion splicing of optical waveguide sections are provided. According to some embodiments, multiple laser beams (from one or more laser) may be utilized to uniformly heat a splice region including portions of the optical waveguide sections to be spliced, which may have different cross-sectional dimensions. According to some embodiments, the relative distance of the optical waveguide sections and/or the power of the multiple laser beams may be varied during splicing operations.Type: GrantFiled: December 6, 2011Date of Patent: October 25, 2016Assignee: Weatherford Technology Holdings, LLCInventors: Mark R.

Patent number: 9127837Abstract: An improved induced draft gas burner assembly for low NOx residential and light commercial gas furnaces is disclosed. The improved burner includes an upstream assembly coupled to a fuel inlet and an air inlet. The air inlet is coupled to a neck extending between the air inlet and the outlet of the neck, both of which may be disposed within an optional chamber. If used, such a chamber also includes an outlet coupled to a burner. In practice, the chamber and neck behave as a Helmholtz resonator that can be tuned to provide an upstream impedance Zup that exceeds the downstream impedance Zdown of the components downstream of the burner assembly.Type: GrantFiled: June 22, 2011Date of Patent: September 8, 2015Assignee: Carrier CorporationInventors: William Proscia, Scott A.

Patent number: 6439055Abstract: A pressure sensor assembly for determining the pressure of a fluid in a harsh environment includes a pressure sensor suspended within a fluid filled housing. The assembly includes a pressure transmitting device which transmits the pressure of the fluid to sensor and maintains the fluid within the housing in a void free condition. The pressure sensor assembly maintains the sensor in a near zero base strain condition and further protects the sensor from shock and vibration. The pressure sensor assembly further includes bumpers that limit the movement of the sensor within the housing.Type: GrantFiled: November 15, 1999Date of Patent: August 27, 2002Assignee: Weatherford/Lamb, Inc.Inventors: Robert J.
