Abstract: A DIGITAL CIRCUIT AND METHOD FOR THE DETECTION OF CALL         PROGRESS TONES IN TELEPHONE SYSTEMS          Abstract of the Disclosure A digital tone detector circuit characterizes the received PCM encoded signals as one of a plurality of call progress tones, voice signals or silence.  The PCM signal is linearized and normalized to a predetermined level in a digital automatic gain control circuit which also provides a signal corresponding to the level of the input signal.  A first circuit is responsive to the linear signal for providing a count of the zero level traversals incurred by the linear signal.  An envelope detector circuit is also responsive to the linear signal for providing a signal representing the envelope frequency thereof.  The composite results corresponding to the signal level, the zero-level traversal count, and the envelope frequency are translated in an evaluation logic circuit to provide an output signal representing the identity of the input PCM signal.  A microprocessor is responsive to a plurality of the output signals from the evaluation logic circuit for determining the cadence of the received PCM signals.

Abstract: ABSTRACT OF THE INVENTION       Relatively long metal microfilaments made from film forming metal material are described. The microfilaments can be used to make superior high strength structural materials and/or can be used as reinforcing materials in plastic and rubber compositions.      The microfilaments are made by forming a liquid film of molten film forming metal material across a coaxial blowing nozzle 5, applying a blowing gas 10 at a positive pressure on the inner surface of the metal film to blow the film and form an elongated hollow tube or cylinder 12 of molten metal.      Means are provided for forming a thinned wall or weakened portion of the molten metal film forming the wall of elongated tube or cylinder.  A transverse jet 13 is used to direct an entraining fluid 14 over and around the blowing nozzle  5  at  an  angle  to  the  axis  of  the  blowing nozzle.  The entraining fluid 14 as it passes over and around the blowing nozzle 5 fluid dynamically induces a pulsating or fluctuating pressure field at the opposite or lee side of the blowing nozzle in the wake or shadow of the coaxial blowing nozzle and produces a laminar flow of entraining fluid in the vicinity of the forming elongated tube or cylinder.  The continued movement of the entraining fluid 14 over the elongated tube or cylinder 12 produces asymmetric fluid drag forces on the tube or cylinder, and at the thinned walled or weakened wall portion longitudinally breaks the tube or cylinder to form a multiplicity of metal microfilaments, and detaches the metal microfilaments from the elongated tube or cylinder and from the coaxial blowing nozzle and the detached microfilaments are carried away from the blowing nozzle.  Quench nozzles 18 can be disposed below and on either side of the blowing nozzle 5 to direct cooling fluid 19 at and into contact with the molten metal microfilaments 17 to rapidly cool and solidify the molten metal to form hardened metal microfilaments 17.

Abstract: OPTICAL REPRODUCING APPARATUS                 ABSTRACT OF THE DISCLOSURE         An optical reproducing apparatus for read-out of information  recorded  in parallel,  substantially  circular tracks on a record disc includes an optical pickup head having an object lens for focusing a light beam at the disc, a tracking servo mechanism for controlling the point of impingement  of  the  light  beam  on  the  record  disc  in directions transverse to the tracks, a jump pulse generator, a drive motor for moving the optical pickup head along a radial direction of the disc,  and a control circuit for driving the motor.   In an access or search mode of the apparatus, the jump pulse generator provides jump pulses to the  tracking  servo  mechanism  by  which  the  point  of impingement of the light beam is made to jump across the tracks toward a desired or target track.  In response to the jump pulses, the control circuit provides respective drive signals for the motor with the duration of each drive signal being greater than the duration of the respective jump pulse to compensate for the effect of the relatively large inertia of the optical pickup head.

Abstract: ABSTRACT OF THE DISCLOSURE:         In a process of regenerating laden absorbent solutions used to desulfurize gases which contain H2S and CO2 and possibly COS, which solutions contain at least one highly volatile secondary amine in an organic solvent, the laden absorbent solution is flashed and stripped with its own vapor.  The overhead vapors from the regenerator, which consists of an indirectly heated plate column, are cooled to approximately ambient temperature.  The resulting con-densate is separated and fed to the top of the regenerator.          The cooled gas is withdrawn.  A partial stream of the vapor is withdrawn from the regenerator 1 to 10 plates below the outlet for the overhead vapors and the inlet for the conden-sate and is cooled to ambient temperature.  The resulting condensate is fed to the regenerator 1 to 10 plates above the inlet for the absorbent solution.  The remaining gas is fed to a re-absorber, in which it is scrubbed in a counter-current operation with at least one partial stream of the absorbent solution, preferably with the effluent from the desulfurization of the gas which contains H2S and CO2 and possibly COS.  The exhaust gas is withdrawn from the top of the re-absorber.  The absorbent solution drained from the re-absorber is fed to the upper portion of the regenerator.       The regenerated absorbent solution is withdrawn and used to desulfurize gases which contain H2S and CO2 and possibly COS.

The attachment of the riser to the ship, and the motion-compensation and pipe handling system on the deck of the ship allows normal production to proceed, while ship motions are isolated from the riser, preventing excessive load transfer or unacceptable dynamic responses.  The riser system is specifically designed for high loading and fatigue endurance and, hence, suitable for mooring as well as production.
