Isokinetic Fluid Sampling Method
US Patent:
5811696, Sep 22, 1998
Filed:
Jul 22, 1997
Appl. No.:
8/898250
Inventors:
Harvey Eugene Jobson - Reston VA
Assignee:
The United States of America as represented by the Secretary of the
Interior - Washington DC
Interior - Washington DC
International Classification:
G01N 120, G01N 114
US Classification:
7386303
Abstract:
A sampler for obtaining an isokinetic sample of a flowing fluid. A liquid-filled, fluid-tight container has a deflated bag within it. The sampler is positioned within the flowing fluid stream, and the liquid is pumped from the container at a rate proportional to the flow rate of the flowing fluid to draw a sample of the fluid into the bag at the same rate as the flow rate of the flowing fluid. When the bag is filled it can be removed from the container and the container inlet tube replaced, allowing the sampler to be used for another sample without laborious cleaning in the field.

Roof Vent Damper
US Patent:
4924760, May 15, 1990
Filed:
Jul 10, 1989
Appl. No.:
7/377075
Inventors:
Harvey E. Jobson - Reston VA
International Classification:
F24F 1100
US Classification:
98 4215
Abstract:
A roof vent damper for closing a roof mounted ventilator in the event of a fire includes a frame formed from an elongated rectangular plate having a central dumbbell shaped cut-out. Longitudinal side edges of the plate are folded over to form parallel guide track members. The plate is then folded along a central transverse line extending across a narrow central portion of the cut-out to form overlying plate members separated by a hollow guide track. A damper plate is received for reciprocal sliding movement in the guide track and is retained in an open position by a fusible link which separates at a predetermined elevated temperature. The damper is biased to a closed position by a coil spring.
