Title: Instantaneous tape position determination in cassette - involves measurement of transfer speed and physical characteristics of tape
Inventor: D ALAYER DE COSTEMORE D ARC T
IPC: G01B7/04
Filed: 1978-12-07
Abstract: The instantaneous position of a tape used for recording and reproduction is calculated from constants representing physical characteristics. The speed of transfer of tape from one spool to another is also measured. Pulses are generated proportional to speed or rotation of eachspool in a tape transfer system. High frequency clock pulses are accumulated in registers to determine time of rotation for each spool from the number of pulses generated proportional to speed. Physical characteristic constants for cassette is use are stored in memory and used in calculations to determine tape position.

IPC: H04M7/14
Filed: 1979-07-20
Abstract: An auxiliary unit (DWE) comprises a dialled number converter unit (U) which allots to incoming selector signals new groups of connector lines belonging to substations, a control unit (ST) which arranges both the line signalling and the voice channel switching, and a couple field (KN) which receives the a-b line voice channel pairs and subject to input from the control unit (ST) makes connection with substation feed lines (ALl to ALn). The incoming cable lines (ELl to ELn) derive from output points of the last (decade) stage in the central exchange, or also from one or more preceding stages; the auxiliary unit (DWE) comprises the necessary signalling means for giving the engaged signal to the calling subscriber when all the access lines are engaged. A feature of the auxiliary unit is also that it includes a switch over unit for determining the direction of the call so that a substation can obtain access to the preselector unit in the central exchange and thus make an outgoing call. The system increases the utilisation factor of central exchange equipment.
