Granted: 1980-07-01
Abstract: ABSTRACT OF THE DISCLOSURE             A method is disclosed for producing cellulosic and/or polynosic fibres having flame-resisting properties, the improve-ment consisting in the fact that a composite viscose is spun in an acidic bath, said composite viscose being obtained by the association in an aqueous solvent, of cellulose xanthate with a phosphorus and nitrogen compound, dissolved in the same aqueous solvent and capable of being converted, while cellulose is being regenerated in said acidic bath, into a state of substantial insolubility.  The phosphorus and nitrogen compound is a compound obtained by reacting a phosphonium derivative with aminoacids and amines and/or ammonia.  A preferred compound is tetrakis-hydroxy-methylphosphonium chloride.  By so doing, an efficient flame-retarding protection is obtained for the fibre without sacrificing the physical properties thereof.  Critical quantities, reaction conditions and test results are reported.

Abstract: MEANS FOR SECURING AND REMOVING MOLDS       FROM COMPACTING APPARATUS          Abstract of Disclosure Individual mold assemblies are releasably secured to a table by latching means in the form of pivotally mounted finger elements which can swing into and out of engagement with a base structure associated with each mold assembly. A separate dumping means functions to engage and lift each mold assembly from the table, so that a part can be dumped therefrom, and the dumping means operates to automatically release the pivotally mounted finger elements from their engagement with a mold assembly when the dumping means is moved to a position for engaging and lifting the mold assembly. The improved means for securing and relasing mold assemblies provides for greater reliability in maintaining critical relationships in mold assemblies than has been possible with known prior arrangements for removing parts from such molds.

Abstract: Abstract of the Disclosure A method for reinforcing concrete comprises short and substantially straight steel flakes of rectangular cross section and small thickness in relation to their length and width. In use the flakes are uniformly distributed and randomly orientated in the concrete. The flakes are relatively difficult to crush and are tapered at each end. They have a thickness of 1 to 5 mm and a length of at least 100 times the thickness. The flakes are made from molten steel of such a composition that rapid cooling of thin layers of the melt produces relatively flexible, difficult-to-crush films. Thus molten steel is impinged upon a relatively cold metal surface of great cooling capacity which is moved rapidly across the direction of delivery of the molten steel. This creates at least one discrete, relatively thin, flake-shaped layer of molten steel on the metal surface. This thin layer is allowed to solidify on the surface to form the desired steel flakes. The flakes can be twisted into slight propeller shapes and have direction-independent strength properties.

Abstract: ABSTRACT OF THE DISCLOSURE           A plurality of widely separated local time base systems are synchronized with a master time base system by means of digitally encoded radio signals.  All of the time base systems comprise oscillator driven digital clocks which produce a cyclically recurring series of sequential time slots which are individually assigned to the master and local systems to provide time division multiple access to the master system from each local system.  Coarse time synchronization is obtained by the transmission of a coarse synchronization signal from the master to each local system at the beginning of the series of slots in the master's time base which resets all local time bases to the beginning of the series of slots. Fine synchronization is mate during the individual time slot assigned to each local system by the transmission of fine synchronization request and fine synchronization reply signals which are utilized to produce a synchronization error signal in each local system.  The error signal is employed to generate frequency and phase corrections for the local oscillator and time corrections for the local clock in accordance with a programmed control state sequence in which the oscillator and clock correction gains used for a particular correction are determined by the number of system cycles between fine corrections and the magnitude of the error.  A digital filter technique is utilizcd which approximates the operation of a simple Kalman filter.

Abstract: ABSTRACT OF THE DISCLOSURE         Electrical leakage between electrodes in an electro-chemical cell is determined by initially overcharging the cell to place it in a fully charged state.  Various methods are available to ascertain a full charge, and a convenient method is disclosed in which the full charge is indicated by a pre-determined rate of gassing at the electrodes.  After receiving a full charge the cell is stored on open circuit for a time, during which some of the charge is dissipated due to leakage, and is then recharged to achieve an onset of gassing condition.          The gas from the cell is conducted to a pressure vessel where it is filtered and slowly exhausted to the atmosphere while the pressure is monitored.  An anomalous delay, relative to a refer-ence cell, in achieving the onset of gassing condition indicates cell leakage.  The method and apparatus disclosed provides a convenient and considerably faster way than previously known to test for cell leakage.

Abstract: ABSTRACT OF THE DISCLOSURE     A hollow disk is carried on a wheeled frame or trolley which is moved over the surface being examined and is slidable perpendicularly to its surface within certain limits.          The disk is double walled and a certain degree of vacuum is maintained in the space between the walls during the apparatus operation.  The disk wall facing the surface being examined is provided with holes and on the outer surface of the same wall a disk of para rubber is spread which is provided with the same array of holes as the hollow disk wall; the holes of the disk wall being aligned with the holes of the para rubber disk.  For each sampling operation, a fresh smear disk is applied on the para rubber layer which adheres thereon by the action of the dynamic vacuum existing within the hollow disk.  The hollow disk is biased outwards of the frame by a calibrated spring inserted between the disk and the frame structure.  The presence of the spring makes the force exerted by the smear disk on the surface being examined independent of the wheeled frame weight.  Said force depends only on the spring characteristics.
