Patent number: 8530787Abstract: A flow tester may use a low impedance flow meter to test a hole at a predetermined Reynolds number. The flow tester may be mounted to a robot so that testing may be fully automated. For example, the flow tester may be incorporated into a laser drilling workcell and used to test flow characteristics of a test coupon or workpiece to calibrate or verify the laser settings. Another example may be used for testing flow characteristics of a finished workpiece. The flow tester may have a testing tip that is compliant to form a seal against a workpiece, and the testing tip may be able to seal against angled, curved, or other surfaces.

Patent number: 7857040Abstract: A heat exchanger for use with exhaust pipes. A shroud inlet communicates with a rear chamber, which communicates with a front chamber via a center plate vent. The front chamber communicates with a shroud outlet. Ambient air entering the rear chamber is routed around at least one J-pipe in the rear chamber, and around a collector in the front chamber, thus being twice heated prior to exiting the heat exchanger through the shroud outlet. The double heating provided by this design increases the efficiency of the heat exchanger. The collector is attached to the center plate by means of a full-penetration fillet weld, and the J-pipes are attached to the center plate, a front plate, and a pipe assembly baffle by stitch welding external to the J-pipes, thus strengthening the integrity of the hermetic seal between exhaust gasses and ambient air passing through the heat exchanger.Type: GrantFiled: September 5, 2007Date of Patent: December 28, 2010Assignee: Power Flow Systems, Inc.Inventor: Thomas J.
