Abstract: Methods and apparatus are provided for determining the pore volume compressibility, the porosity at stress and the relative porosity change of reservoir rock samples. In accordance with the invention, as few as two pore volume measurements of reservoir rock samples are obtained at simulated overburden pressures and relatively low pore pressure. From these data, a bi-logarithmic plot of pore volume versus pressure for a given reservoir rock sample is prepared. From the slope of the plot, pore volume compressibility of the reservoir rock sample at a given overburden pressure is directly calculated. In a further aspect, the intercept of the pore volume versus pressure plot is obtained, and, in conjunction with a measurement of the grain volume of the sample, the porosity at stress and relative porosity change of the rock sample are determined.

The filter medium is of the type which the filtration aid falls off at the end of a cycle and becomes mixed with liquid and redeposited on the filter medium at the commencement of a new cycle. The liquid inlet has a cowl directed downwardly and at the incline to a radius of the container in plan view to direct incoming fluid towards the bottom of the container to properly distribute filtration aid from the container bottom.

Abstract: A suspension containing fine and coarse particles is sprayed under high pressure by way of spray nozzles (10) against a rotating filter medium (7), so that the suspension is separated into a fine fraction, which passes through the filter medium and which contains said fine particles, and a coarse fraction, which does not pass through the filter medium and which contains said coarse particles. According to the invention the filter medium (7) is rotated by way of a drive motor (6) at a speed such that coarse particles and liquid developing on the side of the filter medium are removed from the filter medium substantially as the result of the centrifugal force the coarse particles and liquid are subjected to. In consequence the filter medium is efficiently kept clean during operation, which increases the capacity and improves the separation efficiency.

Abstract: In a hydrocyclone the separation chamber (2) has a circumferential wall (3) provided with at least one turbulence creating member (12), which extends along the circumferential wall and crosses a helical path (10) along which a liquid stream is generated during operation. According to the invention, the turbulence creating member is formed by an offset (12) on the circumferential wall (3). The offset is formed and dimensioned such that said liquid stream substantially loses its contact with the circumferential wall as the liquid stream passes the offset. As a result turbulence is created in a layer of the liquid stream situated closest to the circumferential wall, without the liquid stream developing any substantial flow component directed inward in the separation chamber.

Abstract: Magnetic media containing data and method for data verification are disclosed. The data verification method utilizes the relative position of specific features of magnetic media signals, such as, peak zero crossings, the ratio of preselected amplitudes, the locii of preselected points along the signal, the RMS value of the waveform and the like. In the preferred embodiment, the ratio of the separation of adjacent pulses in the signal is employed. The deviation of the precise location of the placement of the peak points in the signal waveform is referred to as "jitter". This "jitter" is enhanced to provide a pattern of "jitter" or a magnetic "signature" that is random, nonreproducible and that can be used to positively identify a particular specimen of magnetic media and the associated data. The magnetic jitter pattern or security signature can be separate from or an integral part of the data recorded on the magnetic media.

Abstract: A coin guiding device comprises a surface disposed normally in use in the path of a coin, and inclined downwardly toward one side of the path to cause coins which have engaged the surface to tend to move toward that side. The surface is moveable under the weight of the coin in a direction out of the plane of the coin to permit the coin to pass, and is so arranged that the effective leverage caused by the coin increases as the coin moves toward the side of the path.
