Patent number: 11697124Abstract: A Cannabis trichome separator. At least one storage vessels are provided, each vessel having an open top and adapted to receive a plant material and chilled or ice water mixture. A mechanism for agitating the mixture is also provided. Another mechanism raises, lowers, and pivots the agitating mechanism, so the agitating mechanism can be placed over the open top of each of the at least one storage vessels. The mixture can be agitated in each of the storage vessels, seriatim. Also disclosed is a method for processing raw plant material. A plant material and chilled or ice water is introduced into each of at least one storage vessels. The agitating mechanism agitates the mixture in a first of the storage vessels, pivoting the agitating mechanism from a first position to a second position, and agitating the mixture in subsequent storage vessels, seriatim.Type: GrantFiled: December 10, 2021Date of Patent: July 11, 2023Assignee: PUREPRESSURE, LLCInventors: Benjamin Britton, Kyle Manuel

Publication number: 20230079635Abstract: An extraction freeze drying system. The freeze dryer has a cold collector, heating elements, and a vacuum chamber. A first removable collector vessel is operatively and removably connected to the freeze dryer. A second removable collector vessel is provided for replacing the first removable collector vessel upon removal thereof from the freeze dryer. The first and second removable collectors are jacketed vessels. Fluid is allowed to pass through the jacket to maintain proper temperatures. A sealable lid is attached to the first removable collector vessel immediately upon or prior to removal from the freeze dryer. The sealable lid comprises a drain valve and spout to aid in pouring off water or terpenes during the separation process.Type: ApplicationFiled: September 16, 2021Publication date: March 16, 2023Inventors: Benjamin Britton, Kyle Manuel

Patent number: 11299464Abstract: Provided herein are imidazolium polymers having steric hindrance at the 4-position of the imidazole moieties in the polymeric chain. The sterically-protected, N-methylated imidazolium polymers exhibit hydroxide stability in concentrated caustic solutions at elevated temperatures, such as at 100° C. and higher.Type: GrantFiled: July 29, 2017Date of Patent: April 12, 2022Assignee: Simon Fraser UniversityInventors: Steven Holdcroft, Jiantao Fan, Andrew Wright, Benjamin Britton, Thomas Weissbach, Timothy James Peckham, Jonathan William Ward

Patent number: 11230626Abstract: Described herein are crosslinked alkylated poly(benzimidazole) and poly(imidazole) polymer materials and devices (e.g., fuel cells, water electrolyzers) including these polymer materials. The polymer materials can be prepared in a convenient manner, allowing for applications such as anion exchange membranes (AEMs). The membranes provide high anion conductivities over a wider range of operating conditions when compared to the analogous membranes that are not cross-linked. The crosslinked polymer materials have improved alkaline stability, when compared to the analogous non-crosslinked polymer materials.Type: GrantFiled: August 1, 2017Date of Patent: January 25, 2022Assignee: Simon Fraser UniversityInventors: Steven Holdcroft, Thomas Weissbach, Timothy James Peckham, Andrew Wright, Benjamin Britton
