Strain Gage Construction
US Patent:
3940730, Feb 24, 1976
Filed:
Feb 18, 1975
Appl. No.:
5/550516
Inventors:
Given A. Brewer - Marion MA
Assignee:
Brewer Engineering Laboratories, Inc. - Marion MA
International Classification:
G01L 122
US Classification:
338 2
Abstract:
A strain-deformable wire resistance strain gage is cemented to a ship's propeller or turbine blade, and covered with a water vapor curable silicone plastic polymer protective layer in an unset state; a metal screen overlay is tack-welded with the aid of sheet metal strips through the unset silicone plastic to the propeller or turbine blade, after which the protective layer is air cured, forming a seal around the welds and the gage.
Dynamic Vibration Absorber
US Patent:
4150588, Apr 24, 1979
Filed:
Dec 29, 1976
Appl. No.:
5/755268
Inventors:
Given A. Brewer - Marion MA
Assignee:
Brewer Engineering Laboratories, Inc. - Marion MA
International Classification:
F16F 1500
US Classification:
74574
Abstract:
This invention relates to suppression of vibrations in massive systems including large rotating elements such as induction fan rotors used in electric power generating plants. In particular, this invention relates to the provision of a tuned vibration absorber with very low damping, often known as a dynamic vibration absorber, which acts to reduce or suppress the vibration of a system having a resonant frequency near its operating frequency.
Method Of Mounting A Strain Gage To A Surface
US Patent:
4015326, Apr 5, 1977
Filed:
Dec 5, 1975
Appl. No.:
5/637888
Inventors:
Given A. Brewer - Marion MA

International Classification:
B23P 300
US Classification:
29460
Abstract:
A strain-deformable wire resistance strain gage is cemented to a ship's propeller or turbine blade, and covered with a water vapor curable silicone plastic polymer protective layer in an unset state; and metal screen overlay is track-welded with the aid of sheet metal strips through the unset silicone plastic to the propeller or turbine blade, after which the protective layer is air cured, forming a seal around the welds and the gage.
Dilatometer
US Patent:
4290311, Sep 22, 1981
Filed:
Feb 8, 1980
Appl. No.:
6/119709
Inventors:
Given A. Brewer - Marion MA
Assignee:
The United States of America as represented by the United States
Department of Energy - Washington DC
Department of Energy - Washington DC
International Classification:
G01L 702
US Classification:
73730
Abstract:
A dilatometer mountable to the exterior surface of pressurized pipe to measure small pressure variations within the pipe. The dilatometer includes two rigid beams tied together by nonextensible tensile members on opposite sides of the pipe. One member includes a strain gauge mounted to a strain gauge plate. Dilation of the pipe distends the beams, stressing the gauge plate. The strain is physically magnified on the gauge plate due to its position at the end of the beams and in direct proportion to overall diametral variation of the pipe due to pressure fluctuations.
