Patent number: 10438219Abstract: Methods and systems consistent with the present disclosure identify useful ways/means of maximizing levels of participation from a target audience based on identifying a strong positive sentiment toward real-world decisions performed by members of a group of persons. Members of a particular group of persons may be considered a human swarm or a skilled human swarm that provide information relating to factors that prevent group members from making a commitment. Members of a human swarm may have been selected based on a series of tests that identify skilled persons. Once a particular sentiment is identified, that sentiment may be broadened or extended by combining information or by identifying differences (contrasts) between factors, answers, assessments, or forecasts provided by humans as compared to a machine intelligence, via an iterative process that statistically raises a level of participation with members that have strong sentiments regarding a class of products or services.Type: GrantFiled: June 25, 2018Date of Patent: October 8, 2019Assignee: DUAL STREAM TECHNOLOGY, INC.Inventor: Leopold B.

Patent number: 9009905Abstract: A pipe pig for refinery heater tubes is disclosed. The pipe pig has arcuate cleaning elements which form an expandable circumference. Each of the arcuate cleaning elements has a scraping edge. A spring element biases the arcuate cleaning elements radially outward. The pipe pig may have structural components made from titanium alloys and arcuate cleaning elements made from carbon-carbon composites. A method for cleaning coking out of refinery heater tubes using the pipe pig is also disclosed.Type: GrantFiled: July 31, 2009Date of Patent: April 21, 2015Assignee: On Stream Technologies Inc.Inventors: Jantje Been, Baotong Lu, David Crick, Guenther Metzker

Patent number: 8977082Abstract: A filter and fabrication process for a thin film filter that is based on frustrated total internal reflection and multiple waveguide layers, in which the waveguide modes are resonantly coupled. The physics of the design is related to prism coupling of light into planar waveguides, and waveguide coupling between planar waveguides in close proximity. Embodiments include a filter that acts as a bandpass filter and polarizer, a filter that acts as a bandpass filter, polarizer and angle filter (spatial filter), a filter that is widely tunable, and a filter that is widely tunable in both peak transmission wavelength and width. Methods of fabrication are disclosed, and methods to correct for manufacturing errors in thin film deposition are described. The filter embodiments can also be used in reflection as notch filters in wavelength and angle, for a particular polarization component.Type: GrantFiled: January 18, 2011Date of Patent: March 10, 2015Assignee: Stream Technologies Inc.Inventors: Kirat Singh, Elmar Prenner, Alan D.

Patent number: 6569255Abstract: A method of cleaning tubing in an operating heater, in which the tubing has an inlet and an outlet. While the heater is in operation, a hollow, metallic and/or tubular mesh pig is run through the tubing from the inlet to the outlet. Cleaning should be done before contaminant has hardened. An improved pipe pig, preferably hollow, metallic and/or made from tubular mesh, has scraping edges made from longitudinal edges of a wire. The tubular mesh may be a knit, weave or may be knotted. The pig is preferably radially expandable up to twice its fully compressed radius, and may have an expander to force it radially outward. The pipe pig is preferably made of a resilient wire having a polygonal cross-section.Type: GrantFiled: September 24, 1998Date of Patent: May 27, 2003Assignee: On Stream Technologies Inc.Inventor: Orlande Sivacoe

Publication number: 20020185261Abstract: An apparatus for cleaning tubing in an operating heater, in which the tubing has an inlet and an outlet. While the heater is in operation, a pig is run through the tubing from the inlet to the outlet and then returned to the inlet along return tubing, in parallel connection to the heater tubing. A combined pig launcher and receiver mounted parallel to the tubing, and controlled with three-way full port valves, is used to launch pigs into the tubing and remove them from the tubing. A boost pump is used to force pigs back from outlet to inlet.Type: ApplicationFiled: April 11, 2002Publication date: December 12, 2002Applicant: ON STREAM TECHNOLOGIES INC.Inventor: Orlande Sivacoe
