Vertical Displacement Measuring Apparatus
Vertical Displacement Measuring Apparatus
US Patent:
4026156, May 31, 1977
Filed:
Nov 6, 1975
Appl. No.:
5/629640
Inventors:
Philip N. Bowditch - Cohasset MA
William E. Toth - Bolton MA
Arthur Grossman - Framingham MA
William E. Toth - Bolton MA
Arthur Grossman - Framingham MA
Assignee:
The Charles Stark Draper Laboratory, Inc. - Cambridge MA
International Classification:
G01C 504, G01C 920, G01L 718
US Classification:
73432HA
Abstract:
Apparatus for measuring the vertical displacement between a remote point and a reference point. The apparatus comprises a pair of reservoirs, each having a liquid working fluid disposed therein, a differential pressure transducer and a hydraulic coupling means for each of the reservoirs. Each hydraulic coupling means couples a point in the reservoir below the top surface of the working fluid to an associated input port of the pressure transducer. A vapor pressure equalization means is provided for the reservoirs whereby the points above the top surface of the working fluid in each reservoir are maintained at substantially equal pressures. The apparatus further includes a volumetric temperature compensation means for offsetting temperature dependent changes in the volume of the working fluids which occur in the hydraulic coupling means. The pressure transducer provides an output signal representative of the difference in hydrostatic pressure applied to the input ports of the sensing element associated with the transducer.

US Patent:
4495988, Jan 29, 1985
Filed:
Apr 9, 1982
Appl. No.:
6/366931
Inventors:
Arthur Grossman - Framingham MA
Assignee:
The Charles Stark Draper Laboratory, Inc. - Cambridge MA
International Classification:
F28F 2700
US Classification:
165 96
Abstract:
A system for transferring heat from a first (inner) surface through a second (outer) surface. The system includes at least two adjacent porous and thermally conductive layers between the first surface and the second surface. The innermost layer is characterized by a relatively high porosity and the outermost layer is characterized by a relatively low porosity. The innermost layer houses a fluid coolant. The pores of the innermost and outermost layers are coupled, permitting coolant flow therebetween. A vapor chamber is positioned between the outer surface and an outer member. A controller is adapted to control the vapor pressure in the vapor chamber whereby the coolant has a liquid vapor phase transition in the outermost layer.
