Patent number: 10487971Abstract: A weldless sample port assembly is provided herein that may be installed on a conduit carrying a fluid such as an exhaust stack, without a requirement for welding. The sample port assembly comprises a sample tube that passes through two holes in the exhaust stack. The sample port assembly further comprises first and second assemblies located at each end of the sample tube and which respectively provide a sealed interface with the two holes in the exhaust stack. At least one assembly of the first and second assemblies is a floating assembly that comprises a compressive body. The compressive body may help to compensate for expansion and contraction of the assembly and/or sample tube, as well as misalignment in the exhaust holes to ensure that the first and second assemblies maintain a positive seal at all times against the exhaust stack and the sample tube.Type: GrantFiled: June 2, 2017Date of Patent: November 26, 2019Assignee: REM TECHNOLOGY INC.Inventors: Gregory Anthony Brown, Brian Bobyk

Patent number: 10317320Abstract: Embodiments of the invention collect solid, vapor, and/or biological components of the air in air-sampling cartridges that are then transported to an off-site location by pneumatic pressure. Operation proceeds by first collecting a sample of air in an air-sampling cartridge in a sampling position, then advancing a cartridge assembly to move the now-used sampling cartridge into a transport position while simultaneously moving an unused sampling cartridge into the sampling position, and finally using pneumatic pressure to push the used sampling cartridge in the transport position to an off-site location via a transport tube. The sampling operation can begin again while the transport operation is in still in progress. These operations can be pre-programmed locally or triggered by remote communication. Continued operation is possible due to a plurality of unused air-sampling cartridges retained in the cartridge assembly.Type: GrantFiled: October 19, 2016Date of Patent: June 11, 2019Inventor: Brian J.

Patent number: 6845657Abstract: A sample collection device for collecting a sample of drill cuttings from a hole being drilled as the hole is being drilled includes a stem collector surrounding the drill pipe. Pressurized air is injected through the drill pipe into the hole being drilled. The air forms a stream of air-entrained drill cuttings traveling up the drill hole during drilling. This stream of air-entrained drill cuttings is directed by the stem collector into a conduit which directs the stream of cuttings to a sampling device. The sampling device samples the stream of cuttings and creates a stream of sample cuttings which is directed to a diffuser which separates the sample cuttings from the air stream. The sample cuttings are collected in a sample container or in a sample collector from which they are transferred to a sample container or bag.Type: GrantFiled: March 28, 2002Date of Patent: January 25, 2005Assignee: Harrison R.
