Title: Measuring ferromagnetic material content in fluids
Inventor: SANDULYAK ALEXANDR VASILIEVICH
IPC: G01M/
Filed: 1983-04-11
Granted: 1987-03-11
Abstract: A given vol. of the fluid is allowed to flow from an upper vessel (1) to a lower vessel (9) through a magnetic separator (5). The operation is continued until there is a constant residual content of the solid fraction. A decaying alternating magnetic field is applied periodically to the fluid to demagnetise the residual particles. Pref. batches of the fluid of the same vol. and composition are circulated at different flow rates. The batches are repeatedly replaced until a stable residual solid content is reached independently of the flow rate. Pref. the latter is between 0.03 and 0.07 m/sec.

Inventor: SPEER STEPHEN R
IPC: B63H3/04
Filed: 1989-07-07
Abstract: There is provided a self-actuating, variable pitch propeller having a plurality of blades. All of the blades are automatically movable about their axes (10) between a first, relatively lower pitch position (Fig 5) and a second, relatively higher pitch position (Fig 5), substantially simultaneously and equally in response to achieving a predetermined combination of propeller rotational speed and hydrodynamic loading on the propeller blades. The blades are releasably locked to prevent pivoting of the blades, at least in the lower pitch position, but preferably can be locked in both the high and low pitch positions. More preferably, a feedback force is transmitted from the blade to the locking means (112) to vary the locking force in response to the net turning moment on the blade. The locking means are released in response to the combined effects of centrifugal force generated by the blades and other portions of the propeller and the hydrodynamic loading on the blades.

Abstract: In a method and apparatus for studying surface properties of a testpiece, such as refractive index or thickness of a layer or film on said surface, electromagnetic radiation is directed on to the test surface or a reference surface which has known properties, and reflected on to the other surface. The angle of incidence in respect of the incident radiation, in relation to the respective surfaces, are the same, and the surfaces are so arranged that when the radiation is reflected from one surface on to the other, the parallel polarization component of the first reflection is the perpendicular component of the second reflection. Radiation in the same state of polarization as before the first reflection is extinguished by an analyzer, providing for point-to-point comparison between the two surfaces.
