Publication number: 20220176516Abstract: An ice blasting system comprising a hopper to receive bulk ice and a rotary crusher disposed inside the hopper, the rotary crusher having rotary crusher arms that cooperate with anvils to produce crushed ice from the bulk ice. The system includes a rotary feeder mechanism disposed below the hopper, the rotary feeder mechanism having a rotor that includes ice-receiving pockets for receiving the crushed ice. The rotor rotates against an airtight seal block and delivers the crushed ice into a high-pressure airstream passing through the rotary feeder mechanism to thereby entrain the crushed ice into the high-pressure airstream whereby the ice-entrained airstream subsequently exits the ice blasting system through an outlet.Type: ApplicationFiled: March 23, 2020Publication date: June 9, 2022Applicant: Coulson Ice Blast Ltd.Inventor: Kristjan Gottfried

Patent number: 9121275Abstract: Provided herein are multiple variations, applications, and variations for producing electrical power from a flowing fluid such as a gas or liquid under pressure, for example natural gas flowing through a pipeline, by means of one or more positive displacement devices that drive one or more electrical generators. The electrical generators may be immersed in the flow stream together with the positive displacement devices as disclosed, or alternately may be isolated from the flow stream, such as by magnetic coupling, in order to promote longevity and to decrease the risk of accidental discharge or explosion of the fluid in the flow stream. To further decrease such risks, the positive displacement devices may isolate the drive fluid from the environment without the use of dynamic seals.Type: GrantFiled: December 19, 2012Date of Patent: September 1, 2015Assignee: Exponential Technologies, Inc.Inventors: Curtis Patterson, Alejandro Juan, Kristjan Gottfried, Erik Farrell

Patent number: 8887592Abstract: Disclosed herein are several embodiments of rotors (gears) which utilize spherical involute curves to determine the surfaces of the lobes (teeth). In some embodiments the contact surfaces are radial projections of spherical involute surfaces. In other embodiments the contact surfaces have a root and/or tip of a spherical involute curve, but are barreled or otherwise curved to reduce the point stress on each rotor. The rotors may also be configured where torque transfer is provided at a first set of lobes (teeth) and backlash removal is provided on teeth radially opposed to the first set of lobes (teeth). As the apparatus rotates, the position of torque transfer remains substantially the same, as does backlash prevention/removal, but the teeth providing these operations vary. The rotors may also be used for fluid flow.Type: GrantFiled: May 9, 2012Date of Patent: November 18, 2014Assignee: Exponential Technologies, Inc.Inventors: Curtis Patterson, Alejandro Juan, Kristjan Gottfried

Patent number: 8562318Abstract: This disclosure relates to a new multiphase pump with low recirculated volume. This device discloses novel inlet/outlet porting. One of the disclosed improvements is to port the inlet and outlet through the back of the rotors. In the model shown there is only one lobe on the first rotor, and two lobes on the second rotor. The double lobe rotor has the ports provided thru the back, in the lowest point on the buckets between the lobes. If there were more lobes on the two rotors, then the ports would normally be provided in the rotor with the higher number of lobes, preferably in the lowest point on each bucket. The single lobe rotor shown has voids formed in the outer circumference in order to balance the rotor—however, any rotor with more than one lobe may be naturally balanced and these holes may be unnecessary.Type: GrantFiled: August 9, 2010Date of Patent: October 22, 2013Assignee: Exponential Technologies, Inc.Inventors: Kristjan Gottfried, Alejandro Juan, Curtis Patterson

Patent number: 8371949Abstract: An input shaft to output shaft coupling including an input shaft having a first wave surface thereupon, wherein the first wave surface comprises mounds and valleys. The coupling additionally comprises an output shaft having a second wave surface thereupon, wherein the second wave surface comprises mounds and valleys. The coupling in one form additionally comprises a housing substantially enclosing the first wave surface and second wave surface, wherein rotational force exerted upon the input shaft is translated through the lobes of the first wave surface to the lobes of the second wave surface and to the output shaft in turn, and wherein the first wave surface and second wave surface transmit rotational force therebetween through any range of angles to a maximum output angle between a rotational axis of the input shaft relative to a rotational axis of the output shaft.Type: GrantFiled: September 16, 2010Date of Patent: February 12, 2013Assignee: Exponential Technologies, Inc.Inventors: Curtis Patterson, Kristjan Gottfried
