Abstract: ABSTRACT   A  resonant  flyback  boost  circuit  (21)  is  used  to  enchance flyback  performance  by decreasing the time  required  for completing flyback on systems using a cathode ray tube and a magnetic deflection coil (11).  The boost circuit (21)  is parallely connected across the yoke  (11) in  order to sense  a  voltage  peak  which  occurs  at  the initiation of flyback.  The voltage peak is used to initiate a control signal for allowing current to pass from a high voltage source (23) to a supplemental  boost capacitor (33).  When the potential  across the supplemental  boost  capacitor  (33)  exceeds the potential  across  the yoke (11), current flows from the supplemental  boost capacitor (33), to an isolating diode (40) to the yoke (11),  thereby  increasing the current flow through the yoke (11) during the allocated flyback period.       The boost circuit (21) reduces flyback time while maintaining a high input impendance when boost is not being applied.  The circuit (21) can be connected to as few as three points, does not require a separate  sync  pulse  and  has  minimal  degrading  effect  on  forward scanning and stroke writing modes of operation.

Abstract: Abstract:          Disclosed is an intercept system for integrating the   personalized  services   of   switchboard   attendants associated with on-premises PBX switching systems with the capabilities of the intercept system for allowing calling parties the opportunity to complete their own calls to the on-premises switching systems when the telephone extension numbers  of  the  called parties  are  known to the calling parties.   Depending  on  the  mode  of  system  operation selected,   the   intercept system  either   presents  all incoming calls directly to the switchboard attendants, or intercepts all incoming calls and presents the caller the opportunity to  complete  the  call,  or  a  combination  in which incoming calls are first offered to the switchboard attendants for  assistance and then after  a time wherein attendant   assistance   is   not   gained,   the   call   is intercepted and  the  caller  is  given  an  opportunity  to complete  the  call.   When  a  call  is  intercepted  a bidirectional  communication  path  is  established  between the  caller  and  the  intercept  system,  wherein a digital announcement circuit transmits an instructional message to the   caller   soliciting   the  dialing  of   the  desired on-premises  switching system telephone extension  number, and a DTMF receiver collects the dialed extension number digits.  The digits are then outpulsed to the on-premises switching  system  and  the  call  to  the  desired  party  is completed  without  the  intervention  of  a  switchboard attendant.

Abstract: TRUNK CALL PROCESSING SERVICES FOR   HOST COMPUTER INTERCONNECTIONS            Abstract In a communication switching system controlled by a control processor, line port circuit connections are served by line call  processing algorithms and trunk port circuit connections are served by trunk call processing algorithms.  Trunk call processing algorithms offer the user a wide  variety of call processing features and system management capabilities which are not included in normal line call processing algorithms.  Host computer interconnections are typically established between digital line port circuits and therefore,  host interconnections are administered by line call processing algorithms which offer only a limited set of services.  To provide trunk services for host computer interconnections, an auxiliary algorithm has been added to the normal line call processing algorithms to interlink line to trunk call processing.  In particular, when a host computer is served, the normal line call processing algorithm branches to the  auxiliary algorithm.  The auxiliary algorithm simulates the signalling characteristics associated with a trunk port circuit during the call set-up phase of a connection. Following simulation, the auxiliary algorithm intercepts the normal trunk call  processing algorithms.  The control processor "perceives" the service request as originating from an analog trunk port circuit rather than a digital line port circuit, and therefore administers the request according to trunk call processing algorithms.  Call processing features and system management capabilities associated with trunk services are now automatically available for the host computer interconnection.

Abstract: Abstract A method and apparatus for establishing the volume level of a tone generator associated with a keyboard in which the tone generator will output a click tone when each key on the keyboard is actuated.          In establishing the volume level of a click tone, the keyboard is put into a volume setting mode by the actuation of two key members of the keyboard.  The subsequent actuation of each key member will produce a different volume level of the click tone.  The actuating of a key member results in the storing of a count in a storage member.  The storage member is then downcounted until it reaches zero.  Upon reaching the count of zero, processing means generates a pulse train in which the pulse width is determined by the time it takes for the storage member to count down to zero.

Abstract: ABSTRACT: "Method of manufacturing a plurality of optical components"        To a carrier (1, 1') there is cemented a bar of a material (3, 3'), for example glass or a ceramic material, which is subsequently divided, using cuts (7, 7') which extend transversely of its longitudinal direction, into a number of slices (9, 9') which are separately cemented to the carrier. Each slice (9, 9') is provided with a groove (13, 13') which extends parallel to the cuts (7, 7'). The grooves (13, 13') are curved and have a centre of curvature which is situated at the side of the bar (3, 3') which faces the carrier (1, 1'). In the grooves (13, 13') there are secured optical fibres (19, 19') which follow the curvature of the groove, after which a side portion of the fibres which is situated furthest from the carrier (1, 1') is ground off. A flat ground face (21, 21') is thus formed on each fibre (19, 19'). Such ground fibres (19, 19') are arranged so that their ground faces contact one another in order to form directional couplers, after which the slices (9, 9') are detached from the carrier (1, 1').
