Abstract:
An angular accelerometer which employs an annular conduit filled with a dielectric fluid. The conduit is blocked at at least one point and there are piezoresponsive elements mounted so as to have the fluid directly apply pressure thereto. The elements are mounted adjacent to the blocked portion of the conduit, one on either side thereof. The structure is adapted for use with a drilling bit in order to indicate eccentricities during drilling as well as to measure instantaneous angular acceleration.
Abstract:
A method of and apparatus for determining the properties of steam by measuring the temperature thereof, adiabatically expanding a sample of the steam, separating the liquid from the expanded sample of steam, and comparing the chloride ion concentration of the separated liquid to that of the feed water used to generate the steam.
Abstract:
The invention relates to a fender for marine structures such as a support leg or column positioned to elevate a working platform above the water''s surface. The fender is comprised of shockabsorbing members at least partially submerged to receive and absorb the impact of floating vessels, debris or the like. The fender includes cooperatively arranged hydraulic and pneumatic chambers, the hydraulic chamber being communicated with the body of water whereby to be maintained in a substantially full condition. The pneumatic chamber is separated from the hydraulic chamber by a yieldable diaphragm which is displaced into the air chamber as the fender is deformed in response to contact with a large floating body.
Abstract:
The invention relates to an inflatable fender for a marine structure, being so carried on the latter to receive and absorb the shock of a floating vessel or other object as the latter makes contact with the structure. The fender includes a shockabsorbing element adapted to not only absorb the impact of the floating body but to dissipate the force of the impact and recover for a subsequent impact. A second, supporting element includes an inflatable belt of sufficient length to surround a platform support leg. The support element includes an expandable wall which, upon inflation, extends laterally to form an annular, tight grip against the outer surface of the support leg. Thereafter with the fender supported in place, the shockabsorbing element can be provided for as needed.
