Abstract: METHOD AND APPARATUS FOR ELECTRICALLY    DETERMINING PIPE INSIDE DIAMETER                          ABSTRACT     A method and apparatus is disclosed for electrically measuring the inside diameter of a metallic pipe such as oil or gas well casing. The transimpedance of two coaxial coils within the pipe is determined and then resolved into its inphase and quadrature components.  The magnitudes of these two components are linearly combined to generate a corrected measurement output having a lessened sensitivity to the permeability and conductivity of metallic objects.  A signal representative of the inside diameter of the pipe is generated in response to the corrected measurement output and may be recorded as a function of travel distance in the pipe.

Abstract: ABSTRACT OF THE DISCLOSURE         For the purpose of purifying gases, especially gases at elevated temperatures, several filters are arranged side by side, in practice, one filter being subjected to cleaning while the other is in operation.  Although this ensures continuous operation, at least two filter units are needed.          These not only take up a relatively large amount of space but also require a relatively large amount of material and are relatively costly.  According to the present invention, these disadvantages are overcome by dividing the filter into a plurality of chambers, each comprising a layer of bulk material, which is disposed annularly around a central channel for the discharge of the media separated out of the gases.  The chambers are connected to one another through openings pro-vided in the chamber wall immediately above the layer of bulk material.  Each chamber is connected to a raw gas supply pipe and a pure gas discharge conduit.

Abstract: ABSTRACT OF THE DISCLOSURE     A peripheral data storage system employing a data buffer connected to a plurality of data storage devices, such as tape recorders, dynamically reallocates data buffer storage segments among the various data storage devices.  A normal-ized elapsed-time period is established based upon the number of accesses to the data storage devices. When the number of accesses reaches a threshold the need for dynamic reallocation is examined.  During the elapsed-time period the system monitors which of the allocated buffer segments have any data transfer activity at all and also measures the intensity of the activity for the respective buffer seg-ments.  In a peripheral system, the intensity is indicated by the number of channel command retries submitted to a connected host processor for the respective allocated buffer segment.  Based upon the allocation status of the buffer segments and intensity of activities of the respective buffer segments, the buffer allocations are selectively reallocated among the data storage devices.

The rotor comprises at least three pairs of actuating members uniformly distributed around its center and located on two different diameters of said rotor, the actuating members of each pair being radially aligned with respect to the center of the rotor, the number of the actuating members of the rotor located on each of the diameters being equal, one of the actuating members of each pair cooperating with the driving elements of one of the reduction members, the other actuating member of each pair cooperating with the driving elements of the other reduction member.  The outermost diameter of the rotor is less than the diameters on which the driving elements of both reduction members are located, so that during one revolution of the rotor the outer actuating element of each pair of the rotor is retracted inside of the smaller diameter on which driving elements are located.

Abstract: LIGHTWAVE TRANSMISSION SYSTEM   USING HOMODYNE DETECTION            Abstract A coherent electromagnetic wave transmission system includes an electromagnetic wave transmission medium for propagating two orthogonally polarized coherent electromagnetic signals. When received the two polarized signals are separated into an information component and a reference component that is coherent with the information component. The reference component drives an amplifier for producing an amplified reference component that is coherent with the information component.  Mixing the coherent amplified reference component with the information component in a homodyne detector produces a baseband information signal.

Abstract: Abstract of the Disclosure A holographic grating spectrophotometer for detecting ozone and sulphur dioxide in the atmosphere is described which provides automatic calibration and which provides automatic linearity correction for the photomultiplier tube.  Automatic calibration is provided by using a computer to control a stepper motor to move the grating so that the photomultiplier tube receives maximum intensity at the calibration wavelength of 302.1 nm from a mercury source.  Automatic linearity correction is obtained by cycling a wavelength selection mask across exit slits located in the focal plane of the device and firstly combines separately taken counts of two different wavelengths and comparing this sum with the sum of counts of these wavelengths taken simultaneously.  The difference is used to calculate photomultiplier tube deadtime and improve accuracy of the results.  In a preferred embodiment five wavelengths are used to calculate ozone and sulphur dioxide levels, and a stepper motor driving a cylindrical wavelength selection mask permits exit slits to be exposed to predetermined wavelengths one at a time.
