Patent number: 7952709Abstract: The present invention describes a torch for producing a plasma for a spectrochemical analysis comprising: an alumina ceramic injector, a vitreous material inner tube concentric with the injector, and an annular joint between the injector and the inner tube. The joint fixedly attaches the injector and the inner tube together and comprises of an adhesive compatible with vitreous material and alumina ceramic. A method of manufacturing the torch is also described.Type: GrantFiled: March 6, 2009Date of Patent: May 31, 2011Assignee: SCP ScienceInventors: George Feilders, Arthur Ross, Neil Ernest Davison

Patent number: 7731036Abstract: A reversible vacuum filter cartridge for connection to a pair of tubes or other entities to filter a liquid medium placed in one of the tubes or other entities is described. The filter cartridge is comprised of a male coupling and a female coupling. The couplings are interconnected to one another by simply pushing a mating projection of the male coupling into a mating cavity of the female coupling. A connecting port is provided in the male and female coupling and has a conduit communicating with tube connecting ends of each of the couplings which communicate with an open end of a tube connected to each of the couplings. The connecting port is identical in each of the couplings and serves either as vacuum port or an air intake port. A filter disk is retained captive between perforated outer walls of each of the couplings when interconnected together in fluid-tight relationship.Type: GrantFiled: February 15, 2007Date of Patent: June 8, 2010Assignee: SCP ScienceInventors: Arthur Ross, George Feilders
