Patent number: 11872518Abstract: A portable pressure swing adsorption method and system for fuel gas conditioning. A fuel gas conditioning system includes a pressure swing adsorption (PSA) system fluidly coupled to a rich gas stream, the PSA system including a plurality of adsorbent beds and configured to condition the rich natural gas stream and produce therefrom a high-quality fuel gas and gaseous separated heavier hydrocarbons, a product end of the adsorbent beds fluidly coupled to a fuel gas line, wherein the high-quality fuel gas is discharged from the product end and supplied to the fuel gas line, and a feed end of the adsorbent beds configured to be fluidly coupled to the rich natural gas stream or a raw natural gas stream, wherein the produced gaseous separated heavier hydrocarbons are recirculated into the rich natural gas stream or the raw natural gas stream.Type: GrantFiled: December 6, 2022Date of Patent: January 16, 2024Assignee: Coldstream Energy IP, LLCInventors: Jason G. S. Ho, Gerald Bowen Gump, Pedro T. Santos, Xuepei Yuan

Patent number: 11486637Abstract: A system includes a first separator that separates water from a fluid material. The water settles on the bottom of the water knock-out tank. The system includes multiple compressors to boost the pressure of the fluid material. The system includes a second separator that separates condensate from the fluid material. The system includes a mixing pipe that mixes glycol with the fluid material and a first heat exchanger that cools the mixed fluid material and glycol. The system includes a third separator that separates gaseous components and liquid components of the mixed fluid material and glycol and a fourth separator that separates the liquid components of the mixed fluid material and glycol. The system includes a fractional distillation column that heats a first liquid from the fourth separator, gasifying a first portion of the first liquid. A second portion of the first liquid remains liquid and is natural gas liquids.Type: GrantFiled: May 10, 2019Date of Patent: November 1, 2022Assignee: Coldstream Energy IP, LLCInventors: Erik Woodward, Gerald Scott Meinecke

Patent number: 10119086Abstract: A system includes a water knock-out tank that receives a fluid material. Water from the fluid material settles on the bottom of the water knock-out tank. The system includes a mixing pipe that mixes a glycol with the fluid material transferred from the water knock-out tank and a first heat exchanger that cools the mixed fluid material and glycol. The system includes a gas-liquid separator that separates gaseous components and liquid components of the mixed fluid material and cooled glycol and a liquid-liquid separator that separates the liquid components of the mixed fluid material and cooled glycol by density. The system includes a fractional distillation column that heats a first liquid from the liquid-liquid separator. Heating the first liquid from the liquid-liquid separator gasifies a first portion of the first liquid. A second portion of the first liquid from the liquid-liquid separator remains liquid and is natural gas liquids.Type: GrantFiled: February 12, 2016Date of Patent: November 6, 2018Assignee: COLDSTREAM ENERGY HOLDINGS, LLCInventor: Steve Shotts

Patent number: 5443629Abstract: A latent image ink particularly for use in printing forms such as games or coloring books. An offset lithographic press is used for imprinting a substantially invisible image on a sheet of standard paper. The latent ink used to form the latent image is a mixture of potassium ferrocyanide or other suitable color foxing iron complexing compounds, white ink and varnish. A developing solution such as ferric chloride or ammonium sulfate is subsequently added to the paper to render the image visible.Type: GrantFiled: May 27, 1994Date of Patent: August 22, 1995Assignee: Alex Wilson Coldstream, Ltd.Inventors: Jacqueline M. Saville, William G. A. Ferguson

Patent number: 5077876Abstract: An improved spindle assembly for a single or a multiple spindle machine is disclosed. An outer tubular member is mounted for rotation by the spindle machine. An inner shaft is positioned within the tubular member and a collet is movable between a locked and an unlocked position. A workpiece can be removed from the unlocked collet by high pressure liquid from the inner shaft. In one embodiment the inner shaft is rotated independently from the tubular member and is also axially reciprocable. A tool mounted on the inner shaft provides for interior machining at the same time as an exterior operation is being performed. In another embodiment the collet remains axially stationary.Type: GrantFiled: January 5, 1990Date of Patent: January 7, 1992Assignee: ColdstreamInventor: James W. McConkey

Patent number: 4499562Abstract: A mixer of the kind having a work head 50 comprising a rotor 60 rotatable within a stator 70 to cause liquid to flow through the stator and having a mixing and shearing effect in the liquid. The mixer has a motor 12 which is vertically movable within a housing 10 between a raised and a lowered position, by means of a handle 30 which rotates a cam 22 engaging the housing 12. The stator 70 is fixed to the housing 12 by rods 52, and the rotor 60 is fixed to the end of the motor shaft 40, so that movement of the motor 12 moves the rotor between raised and lowered positions. In the raised position the rotor has a mixing effect. In the lowered position the rotor is at the same level as an outlet 78 extending from the stator 60, and acts to pump liquid through the outlet.Type: GrantFiled: November 7, 1983Date of Patent: February 12, 1985Assignee: Coldstream (Engineering) LimitedInventors: John Campolini, Dennis Khaan
