Abstract: A B S T R A C T     METHOD AND APPARATUS FOR DETERMINING THE COORDINATES          OF A POINT ON A SURFACE.    A screen is disclosed on the surface of which a certain number of resistant conducting emitter strips and insulated conducting receiver strips are laid, the emitter strips being parallel-mounted with the terminals of a voltage generator and the receiver strips being interlaid between the receiver strips such that a conducting receiver strip lies between two resistant emitter strips. The electronics of control comprises an exploring stage to control the receiver strip time-related exploration. Thus, when a sufficiently conducting object used to indicate a point, has touched the surface and bridge an emitter and a receiver strips, a higher potential is detected on the corresponding receiver strip and the ordonate Y is given by the strip order number - while the abscissa X is calculated from measuring the potential between each ends of the emitter strip and the object.

Abstract: A PROCESS FOR THE PRODUCTION OF        N- AND O-SUBSTITUTED MONOURETHANES           ABSTRACT OF THE DISCLOSURE       N- and O-substituted monourethanes are produced by reacting at elevated temperature an N-aryl-O-alkyl urethane with a primary monoamine in the presence of a high boiling alcohol and removing the arylamine formed during this reaction from the reaction mixture.  The primary monoamine starting material should be such that it will not distill off during the reaction but must have a boiling point (at 1013 mbar) at least 5°C higher than the arylamine which forms during the reaction.  The high boiling alcohol has a boiling point of at least 190°C at atmospheric pressure.  The reaction is carried out at a temperature of from 180 to 300°C.

Abstract: Abstract:          A recording tape cartridge comprises a cartridge case, a lid member having a front plate mounted on the case to be rotatable between a closed position and an open position.  An opening in the bottom portion of the front plate receives a standard pin of a recording device.  An abutting device projects from the front of the bottom wall of the case to protrude into the opening of the lid member up to a position substantially corresponding to the middle of the thickness of the front plate when the lid member is in its closed position.  This arrangement effectively prevents dust or other dirt entering the case and ensures that any scratches on the front surface of the case are inconspicuous.

Abstract: PROCESS FOR COATING SUBSTRATES WITH AQUEOUS POLYMER DISPERSIONS            Abstract of the Disclosure A process for providing a substrate such as a poly-ethylene terephthalate container with a gas barrier coating of a copolymer of vinylidene chloride is disclosed.  The process includes locating the container to be coated in close proximity to one or more airless spray nozzles and impacting the outside surface of the container with a stream of a stabilized aqueous polymer dispersion such as an aqueous polyvinylidene chloride dispersion.  The impacting force of the stable polyvinylidene chloride dispersion on the surface of the container is suffi-cient to cause selective destabilization of the dispersion at the surface interface to form a gel layer containing the polymer in the continuous phase.  This gel layer serves as an adhesive layer for an overlying layer of the aqueous polymer dispersion as a continuous uniform coating.  The resulting wet coating does not sag or run off.  The coating on the container is then dried in a controlled atmosphere to complete the gel formation throughout its thickness whereupon it is further dried to remove the water from the coating and to collapse the gel to form a film without distorting the container.  The dried coating is smooth, uniform and uniformly transparent.  In operation, the overspray can be collected and returned to achieve greater than 95% material efficiency.  The process can be carried out in a continuous manner to provide a continuously moving series of containers with a uniformly transparent, gas barrier polyvinylidene chloride coating at production rates suitable for commercial applications.

Abstract: ABSTRACT            Method  and device for coherent demodulation of a digit-ally modulated carrier A digitally modulated carrier modulated by phase shift keying or frequency shift keying with phase conti-nuity, transmitted as useful bursts distributed at equal time  intervals with phase continuity from each burst to the  next  burst.  The carrier frequency is recovered by squaring  the  carrier  for obtaining a spectrum and se-lecting  the  carrier frequency  within  said spectrum. Bursts  at  an  acquisition  frequency  having  the same frequency  as the carrier, having a time duration longer than  the  time duration of the useful bursts and having characteristic  features  which  are  particular to said acquisition burst, are sent at times which are separated by  time  periods having a duration which is longer than the  repetition  period of the useful bursts by at least an  order  of  magnitude. The acquisition bursts are re-ceived  along with the useful bursts and squared to pro-vide  an  acquisition  spectrum.  A  frequency  which is double  of  the carrier frequency is selected within the acquisition  period  by  identifying  the characteristic feature of the acquisition bursts.

Abstract: ABSTRACT         An electrochemical cell has an annular flow passage for electrolyte solution.  The cell is designed such that, in an intermediate zone, the passage is of constant cross-section (to achieve high electrolytic activity) and, in end zones, the passage progressively increases in cross-section to a maximum value (to lower the current density in regions in which unwanted deposition of salts may preferentially occur).  The cross-sectional shape of the passage along its length also assists in reducing turbulence in the flow thereby reducing the rate of deposition of salts.  Owing to the low rate of deposition, it is possible to maintain the electrodes relatively clean by current reversal at relatively infrequent intervals.  That enables the cell to be used for longer periods between cleaning operations.

Abstract: ABSTRACT    A telephone operator voice storage and retrieval system is capable  of  presenting  to  the  caller  a  played-back  response message in the actual voice of the operator on duty at the time.         The  operator  is also  able  to  follow-up  the  played-back, previously recorded response message with a conversation with the caller,  without  the caller  detecting  a  change  in  the characteristics of the caller's perceived operator voice.   The storage and retrieval system employs a voice analyzer/synthesizer coupled between a response message memory and an audio interface to the operator's audio equipment (headset).  After the storage of a serves of response messages, prepared by the operator, the system is ready for use in answering incoming calls.   In this playback mode, as incoming calls are monitored, the appropriate operator's voice enunciated response message is accessed from memory and, via the voice synthesizer and an audio interface, that message is played back to the caller.   When the caller speaks again, the operator, who has been on-line the entire time but has been relieved of the need to actually recite the response phrase,  now proceeds to converse with the caller.   The audio interface  contains  automatic  level  control  circuitry  which ensures that there is effectively no difference in the recorded voice played back to the caller and the "live" voice spoken by the operator.  As a result, the storage and retrieval system is listener transparent.
