Patent number: 6902592Abstract: Shown is an apparatus and method for cleaning filter units of an air filtering system using a reverse flow pulse of pressurized air. The filter cleaning system includes a venturi element (36) with a narrowed throat portion (56). A blowpipe (46) is substantially axially aligned with the venturi (36) and has an outlet nozzle (50) that is flared in a substantially conical shape with an included angle that (64) that exceeds an angle at (62) at which high pressure air would ordinarily diverge from an unmodified blowpipe opening. The nozzle (50) is axially spaced from the venturi at a selected distance (70) such that a high velocity pulse of air delivered by the blowpipe (46) through the nozzle (50) is delivered to the outlet portion (58) of the venturi (36) substantially between the outlet opening (62) and the throat (56).Type: GrantFiled: October 25, 2002Date of Patent: June 7, 2005Assignee: United Air Specialists, Inc.Inventors: Thomas B.

Patent number: 6544799Abstract: A modular vial autosampler has a storage area for vials containing samples to be analyzed and at least one modular sampling station. A vial transfer mechanism includes an arm having a gripper that lifts a sample vial from the storage section, and the arm moves it to a station for identification and then to a sampling station, and under central control activates the sampling station for obtaining a sample for analysis. The vial transfer mechanism gripper is movable in X, Y, and Z directions to capture and move a selected vial and includes an alignment guide for the vials. Potentiometers are used for providing signals indicating arm position and the control is provided with updated information for calibration of the potentiometers and also updated position information for the arm relative to a fixed home position is obtained.Type: GrantFiled: August 27, 1999Date of Patent: April 8, 2003Assignee: Tekmar CompanyInventors: Edmund T.
