Patent number: 11351515Abstract: A structural improvement for microwave-assisted high temperature high-pressure chemistry vessel systems is disclosed that among other advantages offers dynamic venting and resealing while a reaction proceeds and eliminates the risk of cross contamination associated with systems that use a common pressurized chamber. The improvement includes a relatively thin-walled disposable liner cylinder that includes one closed end and one open end defining a mouth, and a liner cap positioned in the mouth of the rigid liner cylinder for closing the rigid liner cylinder. The liner cap includes a depending column that engages the inside diameter of the rigid liner cylinder, and a disk at one end of the depending column having a diameter sufficient to rest upon the rigid liner cylinder without falling into the rigid cylinder liner so that the cylindrical liner cap can rest in the rigid liner cylinder at the mouth of the rigid liner cylinder.Type: GrantFiled: March 14, 2019Date of Patent: June 7, 2022Assignee: CEM CorporationInventor: Joseph J. Lambert

Patent number: 10527530Abstract: A venting cap is disclosed for pressure vessels for microwave-assisted chemistry. The venting cap includes a flexible circular cover for closing the mouth of a reaction vessel, a flexible annular wall depending from the circular cover, and a flexible annular ring at the bottom of the annular wall and parallel to the circular cover for positioning the cap on a reaction vessel. At least one indentation in the circular cover minimizes distortion when any contents of a reaction vessel exert pressure against the cap, and at least one opening in the annular wall provides a ventilation path through the cap when gas pressure in a reaction vessel flexes the cap sufficiently to partially disengage at least a portion of the cap from the mouth of the reaction vessel.Type: GrantFiled: April 12, 2018Date of Patent: January 7, 2020Inventors: David A.

Patent number: 10421775Abstract: A precision volumetric liquid dispensing instrument is disclosed that includes two pressure sensors and a fluid passageway with a defined volume portion in communication with the two sensors for receiving and distributing liquid in relatively small volumes. One of the pressure sensors is positioned to measure pressure at one portion of the defined volume portion of the fluid passageway and the other of the gas pressure sensors is positioned to measure gas pressure at a different portion of the defined volume portion of the passageway. At least one valve is in communication with the passageway for moving fluids into or out of the defined volume portion of the fluid passageway, and a processor carries out a step selected from the group consisting of (i) calculating the volume of the liquid based upon the measured pressure and (ii) metering a liquid into the defined volume portion of the fluid passageway until the measured pressure indicates that a desired volume of fluid is in the fluid passageway.Type: GrantFiled: December 16, 2016Date of Patent: September 24, 2019Assignee: CEM CorporationInventors: David L. Herman, Joseph J. Lambert
