Abstract: The invention relates to a method and a device for inlet temperature regulation in heating systems having a multi-boiler installation (1) and a plurality of heating boilers (K1, K2, K3), which in each case have a boiler temperature sensor (F1, F2, F3), a valve (D1, D2, D3) and a recirculating pump (P1, P2, P3), a hydraulic final coupler (HE) connected in parallel between the multi-boiler installation (1) and the thermal load (WV), and an electronic control device (ER1, ER2), which senses signals corresponding to the boiler temperature (T1, T2, T3) and on the basis of the desired value of the inlet temperature and the actual value of the inlet temperature in the primary circuit or secondary circuit controls the boiler temperature (T1, T2, T3) of the heating boilers (K1, K2, K3) and, as the case may be, actuating members and/or pumps, and depending on the sensed heat demand of the thermal loads (WV) switches the heating boilers (K1, K2, K3) on and off and controls their valves (D1, D2, D3) and recirculating pumps (P1, P2, P3); the invention is characterised in that the inlet temperature (VT1) in the primary circuit is not measured via an inlet temperature sensor, but is calculated from the boiler temperatures (T1, T2, T3) in accordance with a mathematical model and is used for regulation purposes under specific operating conditions as the actual value of the inlet temperature. This saves a separate inlet temperature sensor in the primary circuit. <IMAGE>

Abstract: A method for transmitting data messages between subscriber stations of a data transmission device, in which a master exchanges information items with slaves via a multi-point connection. To be able to transmit data messages between any slaves, an address is in each case allocated to the ports of the masters and the slaves. The address of a data message contains a sequence of port addresses. A data message transmitted from slave to slave is transmitted as reply message to a master at higher level than the two slaves and is sent from there as call-up message to the other slave. The method and the circuit arrangement are particularly suitable for branched teleaction networks. <IMAGE>

Abstract: An improved bipolar transistor of a BiCMOS integrated circuit (9) is fabricated by utilizing a shallow trench (64) structure. The shallow trench (64) defines an active base (67) and a self-aligned emitter (69). The base resistance of the transistor is reduced because a vertical, rather than lateral, link base, which connects an extrinsic base (51) to the active base (67), is formed. In addition, the overall area is reduced, which provides for a lower collector to base capacitance.
