Abstract: To implement modern office communications, ISDN networks and ATM networks are integrated together. The transfer between the two networks is performed via so-called interworking units (IWU). In order to be able to represent the individual data of subscribers connected to the ISDN communications systems in the respective terminals of the ATM network (BB), the subscriber number of a calling narrowband communications terminal (SBTLN) of an ISDN communications system is transmitted in the D channel to the interworking unit (IWU) where it is assembled into a packet together with the other signalling information transmitted from this narrowband communications terminal (SBTLN) into the information parts of cells. The cells are then transmitted via the ATM network (BB) to the respective terminating subscriber. The cell packets are dismantled once more in the terminal of this terminating subscriber and a database containing subscriber-specific data is addressed depending on the subscriber number. The corresponding subscriber's inividual data can then be displayed on the respective ATM terminal (ATMTLN). <IMAGE>

Abstract: The invention relates to a method for reducing the power consumption in a mobile system, the mobile system comprising a base station broadcasting messages such as signaling messages to the mobile stations. The stations comprising receiver means for receiving and processing messages broadcast from the base station. The signaling message is divided in parts and transmitted in a number of time slots in the TDMA system. First only a first predetermined part of a signaling message is received, and the signaling message broadcast from the base station is reconstructed on the basis of the part of the signaling message only, and the receiving of the rest of the signaling message is discontinued by switching at least a part of the receiver means of the mobile station in a power saving mode during the said period. If necessary, more information of the signaling message can be received before the reconstruction of the signaling message.

Abstract: In a process of separating a liquid sample having phase portions of different densities by centrifugal separation, a phase separator container is employed. The phase separator container comprises a housing having concentric inner and outer cylindrical walls defining a longitudinal axis and a top wall and further a piston body constituting a bottom wall of the housing. The piston body defines together with the outer cylindrical wall, the inner cylindrical wall and the top wall, an annular chamber for receiving the liquid sample. The piston body is displaceable within the annular chamber for draining a phase portion separated from the liquid sample through a drain conduit means communicating with the annular chamber. The phase separation chamber further comprises a reaction chamber to which the phase portions exposed from the annular chamber is processed. The apparatus further includes a liquid supply means for supplying the liquid sample to the annular chamber, a motor means for rotating the phase separation container round its longitudinal axis at a rotational speed causing a separation of the liquid sample into the phase portions, and an actuator means for displacing the piston body within the annular chamber.

Abstract: 1,253,866. Automatic control systems. SK INSTRUMENTS Ltd. Oct.9, 1969 [Jan.8, 1969], No.1089/69. Heading G3R. In an automatic control system in which the output of a condition sensor is compared with a reference and a difference passed through a transfer function generator, the output of the latter is arranged to be substantially linear over a normal range of errors but is progressively decreased for increasing error outside this range. The difference in output voltages between a thermocouple 14 and potentiometer 16 is passed through a differential amplifier 15 to a free running squarewave multi-vibrator 17 including transistors T6, T7 which control a zero voltage switched thyristor power stage 18 supplying a heater load 19. The amplifier 15 output controls a pair of differentially arranged transistors T8, T9 connected as a long tailed pair having a common emitter resistor R24. At zero output from amplifier 15 transistors T8, T9 have equal effective resistances between emitters and collectors and the multi-vibrator runs with unity mark - space ratio. When the voltage on line A increases, and B decreases correspondingly, the resistance of transistor T8 falls while that of transistor T9 arises altering the mark - space ratio of the multi-vibrator and this process continues until transistor T8 is fully conducting and saturated whereby its resistance is at a minimum value. Further changes in the voltage across lines A, B have effect on transistor T8 whereas the resistance of transistor T9 continues to increase hence the response of the multi-vibrator 17 becomes non-linear with respect to the input. An equal and opposite effect is created when the voltage on B rises with respect to A. It is stated in the Specification that the logarithmic reduction in power at the extremes of the proportional band can give a tapering effect resulting in a power turn down ratio lower than 1 part in 2000. It is envisaged in the Specification that mechanical, pneumatic, or hydraulic control means may be alternatively utilized.
