Abstract: ABSTRACT Hydrogen gas streams containing small quantities of free oxygen are found to form oxygenated reaction products which are strongly adsorbed and interfere with the adsorption characteristics of zeolite adsorption beds used to purify such streams and also to adversely affect the purity of the product gas.  The problem is solved by employing an auxiliary zeolite-containing adsorption bed to dry that portion of the product hydrocarbon gas stream which is utilized in purge desorbing the primary adsorption beds.  This procedure avoids water-loading build-up in the primary adsorption beds and conse-quently avoids increasing water vapor content in the product gas.

Abstract: Abstract of the Disclosure An oxygen sensor particularly useful for detecting oxygen concentration in exhaust gas of internal combustion engine is principally made up of a solid electrolyte tube which is closed at one end, anode and cathode electrode layers respectively formed on the outer and inner sur-faces of the electrolyte tube and a tubular metal shell which tightly receives therein the electrolyte tube, leaving a closed end portion of the electrolyte tube protruded from the shell.  To protect the protruded portion of the electrolyte tube against a direct exposure to a high velocity hot gas stream to be measured and a collision with any external article, without obstructing a rapid and uniform heating of the electrolyte tube by the gas stream, a hood in the shape of a cylindrical tube with a closed end is fixed at its open end portion to the shell to enclose therein the closed end portion of the electrolyte tube.  The hood has a single gas inlet aperture formed in the side wall to extend axially of the hood and open against the gas stream and at least one gas outlet aperture formed in the side wall circumferentially at approximately 180° from the inlet aperture.  The total area of the outlet aperture is smaller than the area of the inlet aperture.

Abstract: HEART SENSOR              ABSTRACT OF THE DISCLOSURE          A reference heart beat is recirculated for compar-ison with an actual heart beat.  First and second voltages are respectively produced with magnitudes representing the rates of recirculation of the reference heart beat and the actual heart beat.  A voltage controlled oscillator produces a signal having a variable frequency dependent upon the diff-erences in the first and second voltages.  This signal is used to synchronize the rate of the reference heart beat with the rate of the actual heart beat.     The actual heart beat may be separated into pro-gressive segments.  The characteristics of the actual heart beat in the progressive segments are compared with the char-acteristics of the reference heart beat in corresponding seg-ments.  An output indication is provided when the character-istics of the actual and reference heart beats in the pro-gressive segments do not coincide.  An output indication is also produced when the amplitude of the signals representing the differences between the rates of the actual and reference heart beats experiences abrupt changes.

Abstract: PHN. 8407.             ABSTRACT:                       The invention provides a coding and decoding system for use with a medium having a bivalent state, for example, a magnetisation direction.  Information bits can be received without restriction on an input.  The information bits are grouped to form information words of eight bits which are translated to code words of nine bits.  The translation is so that no more than two code bits of which none would imply a state transition in the medium directly succeed each other.  In the case of a high storage density of means on the receive of the read side, for example, a Nyquist-II filter.  In order to enable the said restriction to be maintained also between successive code words, a bit is inserted by a keying device on the transmission side between each pair of successive code words, the said bit implying a state transition in the medium.  This bit is extracted again on the receive side.  A code conversion  is thus realised with a coding efficiency of 80%, for which a limited code alphabet suffices.  Resynchronisation can be effected with a high accuracy on the basis of the quickly recur-ring transition instants.

Abstract: AUTOMATIC PATTERN PROCESSING SYSTEM                     ABSTRACT An automatic system is described wherein pattern represen-tations of epidermal ridges, such as fingerprints, are uniquely described by the extraction of specific information.  Specific information such as ridge contour data, describing the ridge flow in the fingerprint pattern and minutiae data, principally describing ridge endings and bifurcations, are identified and extracted from the fingerprint pattern.          Topological data, identifying singularity points such as tri-radii and cores, as well as ridge flow line tracings related to those points are extracted from the ridge contour data.  The extracted information is then utilized by the system  to automatically per-form classification of the fingerprint pattern and/or matching of the fingerprint pattern with patterns stored in a mass file.         Identification is automatically achieved by comparing the extracted information with the information stored in the mass file corre-sponding to previously identified fingerprint patterns.  In a simplified version of the automatic system,  verification of claimed identity may be achieved by matching the fingerprint pattern with a particular pattern stored in a mass file according to the claimed identity.

Abstract: ABSTRACT OF THE DISCLOSURE             This invention relates to filter structures for filter pin electrical connectors, and is more particularly concerned with pi filters for filter pin application.  The prior art recognizes several approaches to the provision of pi filters for filter pin applications.  Generally speaking, the pi filters have heretofore taken up too much space and were expensive.  As an example, it is common in the art to provide a two unit multicapacitor with a ferrite insert and to connect the struc-ture between the pin contact and the metal shell of an electrical connector.  This requires two contacts to the capacitor terminations in two locations, one for each capacitor.  An electrical connector assembly constructed in accordance with the present invention comprises a metal connector shell which carries a dieletric member therein.  The dielectric member includes a contact passageway therethrough for receiving and mounting a pin contact.  A hollow tubular inductance, in the form of a ferrite tube, is provided for receiving the pin contact therethrough. The ferrite tube has an inner electrical contact area on the inner surface which is electrically connected to the pin contact and at least one outer contact area on the outer surface which is electrically connected to the inner electrical contact area.  A plurality of planar capacitor ground plates are spaced apart and connected in common to the metal connector shell, while another plurality of capacitor plates, the positive plates, extend between the ground plates and are electrically connected to the outer contact area of the ferrite tube.

Abstract: A catamenial tampon having as the absorbent element a resiliently compressible hydrophilic foam member, including foam-fiber composities, enclosed in an elongate, closed-end sleeve of fluid-permeable sheet material, assembled in a manner to improve withdrawal characteristics after use.  The foam member is made up of an oblong rectangular strip of resiliently compressible hydrophilic polyurethane foam curled or rolled up along its length into a shape which proximates that of a hollow right cylinder in which the ends of the curled up foam strip forming the cylinder are in contact or overlap but are free of attachment to each other.  The approximate cylindrical shape of the foam member is maintained by confinement inside one end of a loosely-fitting sleeve.  The long axis of the sleeve coincides with the axis of the foam cylinder and the sleeve length is substantially greater than the length of the cylinder.  The opposite unoccupied end of the sleeve is gathered and secured together to provide a tapered withdrawal end to which a withdrawal string is attached. - 1a
