Patent number: 11119290Abstract: An alignment device having two angular degrees of freedom is provided. The alignment device is adjustable such that it is suitable for aligning a first apparatus with respect to a second apparatus. The first apparatus may emit one or more of electromagnetic waves, acoustic waves and matter towards the second apparatus and for detection by the second apparatus. The first and second apparatuses may be disposed in a harsh environment such as is found in the vicinity of an industrial process stack. In some embodiments the first apparatus is a laser, preferably a tunable diode laser, and the second apparatus is a receiver incorporating a detector. In these embodiments the apparatuses may be used to perform laser absorption spectroscopy on a process gas flowing through an industrial process stack.Type: GrantFiled: July 29, 2015Date of Patent: September 14, 2021Inventors: Ian C. Gaskin, James D. Hobby, Richard P. Kovacich, Martin Lopez, Graham R. Terry

Patent number: 9546902Abstract: A method and system for correcting the effect of intensity fluctuations of the transmitted light in an absorption spectroscopy system used for the detection or measurement of chemical species in a medium, whereby one or more modulation bursts are imposed onto a light beam that passes through the medium. This burst signal may be obtained by modulating the bias current of a tunable diode laser, and the modulation burst signal may be optimally at the second harmonic of the modulation frequency of a wavelength modulated beam to allow usage of the same signal path processing used for the spectroscopic detection of the measurand for a second harmonic detection system.Type: GrantFiled: March 19, 2015Date of Patent: January 17, 2017Assignee: Servomex Group LimitedInventors: Richard P. Kovacich, Bahram Alizadeh, Ian C. Gaskin, James D. Hobby, Martin Lopez

Patent number: 9091658Abstract: This present invention relates to a device for the measurement of the amount of oxygen in a gas mixture, or other gas with significantly different magnetic susceptibility than the background gas mixture, by the use of a suspended test body in a magnetic field that experiences force due to the magnetic susceptibility of the measurand gas. In order to enable a fast time response for the system with a change in oxygen concentration, a flow regime is presented which allows a fast sweep of the measurement volume combined with adjustable, balanced pressure drops via a flow balancing element (or elements) within the flow channels to independently minimise flow related uncertainties.Type: GrantFiled: February 3, 2012Date of Patent: July 28, 2015Assignee: Servomex Group LimitedInventors: Ian C. Gaskin, Richard P. Kovacich, Christopher R. Edwards, James D. Hobby, Martin Lopez

Patent number: 8847579Abstract: An apparatus for the measurement of the magnetic susceptibility of a gas mixture comprises: a gas sample chamber (8) adapted to receive the gas mixture; a test body (1) rotatably suspended within the gas sample chamber; magnets (10) within the gas sample chamber; a compact optical system for detecting rotation of the test body (1) including a light source (12), photodetectors (13) arranged to detect a light signal, and a mirror (5) attached to the test body (1). An actuation system is arranged to keep the test body (1) substantially at a null position. The optical system comprises at least one photodetector positioned on each side of the light source. The light source is arranged to emit a light beam towards the test body. The photo detectors are arranged to each detect an edge of a light beam reflected from the mirror.Type: GrantFiled: May 27, 2009Date of Patent: September 30, 2014Assignee: Servomex Group LimitedInventors: Richard P. Kovacich, Colin G. Stocks, Christopher R. Edwards, James D. Hobby

Patent number: 7753582Abstract: A sensor for determining the thermal conductivity of a fluid comprising a sensing module located within a housing having inlet and outlet ports for a fluid under test, the sensing module comprising a reference base surface and a sensing element spaced therefrom and having measure and reference sections, and there being provided electrical power monitoring means for monitoring the power through the measure and reference sections in order to generate a signal indicative of the power difference due to thermal conductivity through the fluid. The sensing element is a thick film printed disc with measure and reference resistors printed on it. All changes in the fluid are common to both the measure and reference sections except for the thermal conductivity of the fluid itself.Type: GrantFiled: March 19, 2007Date of Patent: July 13, 2010Assignee: Servomex Group LimitedInventors: Martin Lopez, James Hobby, Bahram Alizadeh, Richard P.
