Patent number: 8256307Abstract: Testing of engine particulate matter production during a transient is made more accurate by selecting an appropriate sized opening for a test probe of the sampling system located in the exhaust line upstream from a particulate trap. By examining the pressure signature at the test probe location and utilizing that information in conjunction with a desired volumetric flow rate into the sampling system, a flow opening size for the test probe can be selected that reduces potential oversampling which may be otherwise induced due to the back pressure increases in the exhaust line caused by the presence of the particulate trap. The flow opening into the test probe of the sampling system behaves relative unrestricted when pressure differentials at the test probe location are relatively low, such as during steady state operating conditions, but restricts flow into the sampling system when pressure differentials are relatively high, such as at a pressure during a transient event.Type: GrantFiled: October 24, 2008Date of Patent: September 4, 2012Assignee: Caterpillar Inc.Inventors: Russell R.

The fluid sampler (50) is actuated to establish fluid communication between an interior (56) and an exterior of the fluid sampler (50) such that a fluid sample is obtained from the well in a chamber (92) of the fluid sampler (50). The fluid pressure in the coiled tubing string is then increased, which pressurizes the fluid sample in the chamber (92). Thereafter, the coiled tubing and the fluid sampler (50) are retrieved to the surface with the pressurized fluid sample remaining above its saturation pressure during collection and retrieval to the surface.Type: GrantFiled: November 13, 2008Date of Patent: June 28, 2011Assignee: Halliburton Energy Services, Inc.Inventors: Cyrus A.

Publication number: 20110083520Abstract: Devices using a winch are currently used for taking samples in the boundary layer formed at the bottom of a water basin. In order to minimize the potential mixing effect at the whole length of the sampling tube, the design is presented where the sampling tube disassemble into sections is provided with horizontal valves dividing the interior of the tube into layers isolated from each other in the presented application, several shorter sampling tubes are used with their inlet holes being located at different heights. Thus, layers located at different heights are sampled by different sampling tubes. Substitution of contacts elements (shoes) with a contact surface, e.g. inflatable support belt, guarantees the stability of the sampling tube on the soft bottom. To ensure the vertical stability of the sampling tube, the device is provided with an upper stabilizing balloon.Type: ApplicationFiled: September 8, 2010Publication date: April 14, 2011Applicant: OU DIMENTIOInventors: Martin Voll, Ants Erm, Andres Voll, Mehis Voll

Patent number: 7874221Abstract: A sample pump system for metering the amount of sample taken from a pressurized fluid process such as a natural gas pipeline or the like, the sample pump system designed for immersion, directly or indirectly, into the pressurized fluid stream so that the sampling is taken at the prevailing pressure and temperature of the fluid stream. A spot sample cylinder device is further provided which employs a method of collection wherein the initial cylinder volume of the collection vessel or sampling cylinder is zero. The spot sample cylinder is inserted into the pressurized gas (or fluid) source, 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.Type: GrantFiled: December 26, 2008Date of Patent: January 25, 2011Assignee: A+ Manufacturing, LLCInventor: Donald P.
