Abstract: BUFFERING SPEECH SIGNALS IN A TASI SYSTEM            Abstract of the Disclosure A time assignment speech interpolation (TASI) system includes a speech buffer comprising storage packets which are assigned to the individual channels as required for the storage of the signals of each off-hook channel.  For each inactive channel, the signals are stored sequentially and cyclically in one packet.  When the channel becomes active, the sequential storage of signals continues in this and in further packets as required, signals stored before detection that the channel had become active being retained in the first packet to accommodate the response time of a speech detector of the system. Clipping of speech signals is thereby avoided.  The channel is assigned a transmission facility and channel-to-facility assignment information is transmitted, following which the signals of the relevant channel are read sequentially from the buffer packets and transmitted via the facility.  Freeze-out of speech signals is reduced because there is a variable delay between storage of signals in the buffer and reading therefrom; reading takes place only after a transmission facility has become available and has been assigned to the channel.  At the end of each speech burst an end-of-record signal is stored in the buffer following the last signal of the channel; this is detected on reading from the buffer to terminate the reading and to indicate that the facility is available for a new assignment.  Rapid updating of packets for writing into and reading from the buffer is achieved by assigning, to each channel or facility for which storage or reading is taking place, not only a current packet of the buffer which is currently being used for storage or reading, but also a back-up packet which is the next packet to be used for the storage or reading operation.

Abstract: Abstract An electromagnetic clutch has a toothed driving clutch member and a toothed driven clutch member which are moved together upon energization of an electromagnet with their teeth in engagement.  A spring disengages the teeth when the electromagnet is deenergized.  The spring provides a relati-vely large spring force for initial breakaway to overcome residual magnetism and metal to metal contact of the teeth.  After initial breakaway, the spring provides only sufficient force to further separate the members.  With this arrangement, a small magnet may be used to engage the clutch because the large force of the spring must be overcome only during final engagement of the clutch.

Abstract: ABSTRACT OF THE DISCLOSURE An automatic telephone answering device employs a single magnetic tape and a single driving mechanism for driving the magnetic tape.  Whenver an incoming call is received, a control circuit of the device sets the driving mechanism into a playback mode to play to the calling party an outgoing message recorded at the beginning of a track on the single magnetic tape. Then, if there have been no previously recorded incoming messages, the device records the calling party's incoming message after the end of the outgoing message.  However, if any incoming messages have been recorded previously on the same track of the single magnetic tape, the tape is advanced at high speed to a point beyond the last of these previously-recorded incoming messages.  Then, the present incoming message is recorded.  As soon as the incoming call is ended, the device is set into a rewind mode.  When the beginning of the recorded outgoing message is reached, the driving mechanism is stopped, and the device stands by to greet the next incoming call with the recorded message.  In a preferred embodiment, a counter counts the rota-tions of a reel drive of the driving mechanism, and its contents are stored for points corresponding to the beginning and end of the outgoing message and the end of each recorded incoming message. The stored contents are then compared with the count on the counter during operation.  A coder can be included to record a code identifying the sequence number of each incoming message.
