Abstract: METHOD AND APPARATUS FOR VENTILATING           AN OCCUPIED SPACE                Abstract of the Disclosure Method and apparatus for controlling the amount of outside air introduced into a given space being ventilated as a function of the oxygen content of the air in the space to minimize the energy expended in heating or cooling air flowing through the space while maintaining the oxygen content of the air above that required for the well-being of humans occupying said space.  A fuel cell produces an electric current the magnitude of which is a function of the partial pressure of the oxygen present in the air surrounding the fuel cell.  The output of the fuel cell is applied to a control circuit which applies control signals to the motor control circuit of a damper motor to admit outside air when the partial pressure of the oxygen in the occupied space falls to a predetermined minimum level and to exclude outside air and to recirculate return air when the partial pressure of the oxygen in the space rises to a certain maximum level.

Abstract: ABSTRACT OF THE DISCLOSURE        Communication cables with cores that have groups of conductor pairs, that carry messages in opposite directions, in the same cable present the problem of crosstalk between the different groups.  With the increase in carrier frequency that is used for communication, the crosstalk problem increases and cables that were acceptable for lower frequency are no longer adequate.  This invention provides more ef-ficient shielding; is suitable for higher frequencies, pro-vides a stronger cable structure; and reduces corrosion of the shielding.

Abstract: ABSTRACT A centrifuge apparatus and a method of using the apparatus to make hollow glass microspheres and hollow glass vacuum microspheres.  The centrifuge has a rotor with a plurality of coaxial blowing nozzles disposed in the outer peripheral wall of the rotor.  Molten glass is supplied to the centrifuge and by centrifugal force is caused to coat the inner wall surface of the rotor and be fed to the coaxial nozzles.  A blowing gas or metal vapor blowing gas is supplied to the centrifuge and fed to the coaxial blowing nozzles.  An entraining fluid is also supplied to the centrifuge which flows through the centrifuge and is directed at the coaxial blowing nozzles.  The hollow glass vacuum microspheres are made by forming a liquid film of molten glass across the coaxial blowing nozzles, applying a metal vapor blowing gas at a positive pressure on the inner surface of the glass film to blow the film which combines with the centrifugal force to form an elongated cylinder shaped liquid film of molten glass which is detached by a jet to form a hollow sphere.  During formation of the microsphere, it is subjected to an external pulsating or fluctuating pressure having periodic oscillations, to assist in formation of the microspheres and their detachment from the blowing nozzle orifices.  The inventive apparatus and method enable the production of microspheres having uniform size and more controlled and predictable physical and chemical characteristics than has been possible by previous methods.

Abstract: Dkt. 54.1302 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          Non-coded and coded information are merged in a copier-printer system by copying the non-coded information onto one or more sheets of paper during a first pass of the sheets of paper through the system and thereafter selecting the sheets of paper with the non-coded information copied thereon from the secondary or duplex paper trays of the system for a second pass through the system during which coded information may be printed on the sheets of paper. Selection of the sheets of paper having non-coded informa-tion copied thereon is integrated with sheets of paper from the primary tray which are to contain exclusively coded information.  Copying of the non-coded information and printing of the coded information is carried out under the control of mag cards indicating the pages and page loca-tions within a given document where the non-coded informa-tion is to be copied and in some cases containing coded information to be integrated with the non-coded information In one method, non-coded information is copied on sheets of paper which are then electronically collated and inverted before being removed as a stack from the exit tray and placed upside down in the secondary tray for subsequent integration with sheets from the primary tray as coded information is printed.  In an alternative method, the sheets of paper having non-coded information copied thereon are collected in the duplex tray with each sheet then being cycled through the system without copying or printing thereon so as to be inverted upon return to the duplex tray in preparation for printing of coded information.  In a further alternative method, sheets of paper onto which the non-coded information has been copied are removed from the exit tray and thereafter selected from the secondary tray to make a complete set of copies which is thereafter used as originals to make further sets of copies.
