Filed: 1973-10-29
Abstract: 1421891 Looped TDM systems BATTELLE INSTITUT eV 29 Oct 1973 [30 Oct 1972] 50167/73 Heading H4K In a looped TDM interconnection system, each subscriber is permanently allocated a time slot in which to receive delta-modulated digital signals emanating from another subscriber. To complete a connection a subscriber depresses a button 9 corresponding to the required subscribers address, and the address is stored and displayed at 11. If the called subscriber is free the address of the calling subscriber is automatically transmitted in the called subscribers time slot and is displayed on the display 11 at the called subscriber station; in addition a ringer is caused to operate. The call is accepted by the depression of a button corresponding to the calling subscribers time slot and the depression of an anti-intercept button. If the called subscriber is busy as indicated by the occurrence of " 1 " bits in his time slot, the visual display of his address ceases at the calling station and the address is fed to a hold store 30. When the called subscriber becomes free an automatic second attempt is made to establish the connection. A synchronization unit 4 is provided for synchronizing the stations to define the time slots. The unit also acts as a retransmission unit for the information circulating in the time slots.

Abstract: 1454413 Digital control of printers and displays SIEMENS AG 1 Nov 1973 [1 Nov 1972] 50892/73 Headings G4H and G5C [Also in Division H4] The invention relates to the analog reproduction of digitally stored alphanumeric characters, each character being stored in matrix form and the signals representing the elements of each matrix row or column being applied to a reproduction device twice in direct succession. A store 6 contains 64 characters each stored as a 7Î5 matrix of short-circuited dots and a character is read out under the control of a column scanner 8 and a "column-dot" scanner 7, each column being scanned twice in succession since the frequency F2 of the pulses controlling the column scanning is halved at 11. Alternatively, store 6 may be arranged to output each column twice in succession when each column is scanned once. The output Z II  from the store is fed to a D/A converter 1 which receives a binary signal ABC representing a repeated count of 0- 7. Each 1-level in signal Z causes the instantaneous value of ABC to be output to resistors 2-4 to produce an analog signal r.J tot  which is fed to an ink jet printer or an oscilloscope. It is stated that the double readout of each column results in reproduced characters of greater contrast than hitherto.
