Patent number: 9200986Abstract: A system for insertion of a probe into a pressurized fluid stream by means of a threaded body formed to engage an elastomeric seal employed to form a fluid barrier thereabout. The present invention contemplates a system which effectively lessens resonance vibration effects and associated damage resulting there from in fluid sampling probes operating in high velocity fluid streams and the like, utilizing mechanical dampening properties associated with its seal(s) and insert(s), forming non-rigid attachment to support the length of the probe in a manner which facilitates resonance absorption and dampening, so as to lessen associated vibration/oscillation in the system. The threaded body forms, in effect, helical strakes to facilitate aerodynamic stabilization and reduce oscillations/vibration, as well as reduce force and deflection caused by high velocity fluid flow passing thereby.Type: GrantFiled: February 12, 2013Date of Patent: December 1, 2015Assignee: A+ Manufacturing, LLCInventor: Donald P Mayeaux

Patent number: 8904886Abstract: A moveable end (ME) sample cylinder device is provided which employs a method of collection wherein the initial cylinder volume of the collection vessel or sampling cylinder is zero. The sample cylinder is inserted into the pressurized gas (or fluid) source for spot sampling thereof, said sample cylinder employing a piston or moveable end configured such that purging of the cylinder sample cavity is not required, since the sample cavity volume is essentially eliminated prior to sampling by the location of the piston within the cavity, the cavity expanding upon sampling via piston movement within the cavity. Also contemplated is a cap/body (CB) spot sample cylinder having a low internal volume and which can be inserted into a pressurized process through common valving. Insertion of the CB sample cylinder into the process eliminates purging of interconnecting tubing and also eliminates the impact of low ambient temperatures which can otherwise alter the spot sample composition.Type: GrantFiled: December 14, 2010Date of Patent: December 9, 2014Assignee: A+ Manufacturing LLCInventor: Donald P Mayeaux

Patent number: 8616228Abstract: A multi-stage pressure regulator system. The system of the present invention provides for distribution of the Joules-Thomson (J-T) cooling effect between multiple stages. In the preferred embodiment of the present invention, the pressure is first reduced by a set ratio in one or more stages followed by an adjustable pressure output stage. The present invention thereby provides a system to control pressure reduction and thus prevent condensation (and associated distortion of a vapor composition sample) of a gas due to J-T cooling effect. The system of the present invention is particularly suitable for use placement (via, for example, a probe) within the source gas supply containment vessel, pipeline or the like, so that pressure reduction occurs at or near isothermal conditions, further lessening the likelihood of J-T condensation.Type: GrantFiled: May 24, 2012Date of Patent: December 31, 2013Assignee: A+ Manufacturing, LLCInventor: Emma Lee Aymond Mayeaux

Patent number: 7886624Abstract: An assembly for insertion and retraction of probe or probe-like device which does not require a seal or packing gland, instead utilizing pressure equalization between pressurized process fluids and the housing containing a probe, so as to negate the use of a dynamic seal. The preferred embodiment of the present invention contemplates an inserting/retraction mechanism for raising and lowering the probe into and from the pressurized fluid, respectively. A housing having a valve is configured to allow fluid communication between the pressurized fluid source, and the interior of the housing assembly. A conduit engages the housing assembly, and is formed to slidingly receive the outer diameter of the probe therethrough, such that a sliding seal maintains a fluid seal between the outer wall of the probe and the inner wall of the conduit, as the probe is telescoped therethrough during insertion and retraction of the probe into/from the pressurized process.Type: GrantFiled: August 9, 2007Date of Patent: February 15, 2011Assignee: A+ Manufacturing, LLCInventor: Donald P.

Patent number: 7875109Abstract: A gas sample cylinder outlet valve having a flow restricting element associated therewith. The preferred embodiment of the flow restricting element comprises an orifice constructed of a low thermal conduction material such as a plastic. Preferably the outlet valve Cv characteristic is large relative to the orifice Cv characteristic resulting in essentially all of the gas pressure drop taking place across said orifice and therefore essentially all of the J-T effect cooling taking place at said orifice. Due to the low thermal conductivity construction of said orifice an insignificant amount of cooling takes place upstream of the valve mechanism. Test have shown that the integral orifice outlet valve having a large Cv characteristic is more efficient then the typical sample cylinder outlet valve and extension tube and/or flow restrictor combination.Type: GrantFiled: March 7, 2008Date of Patent: January 25, 2011Assignee: A+ Manufacturing, LLCInventor: Donald P. Mayeaux

Patent number: 7555964Abstract: A method and apparatus for the physical separation of components from a multi-phase fluid stream into its component phases. More particularly, the invention relates to a housing for a phase separation medium which allows one to change the phase separation medium without the necessity of disconnecting the flow lines. An alternative embodiment of the present invention contemplates a housing incorporating a unique internal valve configuration for controlling and limiting the fluid pressure differential across the sheet of phase-separating material. The internal valve begins to throttle or reduce the fluid flow rate through the sheet of phase-separating material after the differential pressure across the sheet of phase-separating material exceeds a preset value. If throttling the fluid flow rate cannot prevent the differential pressure from exceeding the preset limit, then the internal valve will shut off the fluid flow completely.Type: GrantFiled: September 13, 2004Date of Patent: July 7, 2009Assignee: A+ Manufacturing, LLCInventor: Donald P. Mayeaux

Patent number: 7555965Abstract: A system for obtaining a representative sample of a natural gas stream, particularly a stream which is at or below its hydrocarbon dew point temperature (H.C.D.P.). The preferred embodiment of the present invention contemplates a sample cylinder having a flexible isolation barrier and integrated valving to provide a controlled ingress of sample gas at nominal pressure differential. The system thereby avoids throttling of the sample gas and the inherent cooling problems associated therewith when the stream is at or below hydrocarbon dew point temperature. The flexible isolation barrier of the present invention is relatively inexpensive and is configured for quick and easy replacement, which may be routinely performed to insure sample integrity. Alternative embodiments of the invention contemplate a spherical sample cylinder configuration with flexible isolation barrier, as well as an improvement for piston-type sample cylinders to provide constant sample pressure.Type: GrantFiled: March 14, 2007Date of Patent: July 7, 2009Assignee: A+ Manufacturing, LLCInventor: Donald P.
