Process, service computer, switching centre, terminals and program modules for handling incoming telephone calls during and online data-network session blocking a subscriber line

The present invention relates to a process and also to a service computer, a switching center, terminals, program modules and memory means with program modules for handling incoming telephone calls for a subscriber line (VA1) of a telecommunications network (PSTN) during an online data-network session blocking the subscriber line (VA1). In this process a terminal (TERA) sets up a connection (VA11, VA1, VPOP1) to an online data-network access device (POP) via the subscriber line (VA1). Thereupon the online data-network access device (POP) sends current access data to the terminal (TERA), which the terminal (TERA) signals to a service computer (SCP) of the telecommunications network. If a switching center (SW1) of the telecommunications network then detects an incoming call destined for the subscriber line (VA1), the switching center (SW1) then signals the fact that this call is waiting to the service computer (SCP) which supplies at least one predetermined service for the purpose of processing the incoming call. The service may, for example, consist in a message being sent to the terminal (TERA), in which attention is drawn to the incoming call, or in the incoming call being forwarded to an alternative destination (TELA2).

Flooded evaporator

A flooded evaporator is provided which can remove floating mist more exactly resulting in that the refrigerant mist is prevented from being sucked into the compressor, and with which heat transfer between the medium to be cooled and refrigerant liquid is improved. The evaporator is composed such that; a tubular housing (3) is provided to erect from a horizontal cylindrical container (1) which forms a heat exchanging section with a heat exchanger (2) accommodated therein, an inner tube (12) for upwardly guiding refrigerant vapor generated in the heat exchanging section is provided, the inner tube (2) is covered by a loose cover (13) so that refrigerant vapor containing refrigerant mist flowed up in the inner tube (12) impinges against the loose cover (13) to be deflected downward to flow out from the inner tube (12), a space (17) is secured in the tubular housing (3) to allow refrigerant mist to fall down utilizing gravitational attraction, a demister (16) is provided in the tubular housing (3) above the space (17), the clearance area between the inner tube (12) and loose cover (13) is smaller than the clearance area between the outer periphery of the loose cover (13) and inner periphery of the tubular housing (3), and circulation paths (20) of refrigerant liquid are formed in the container (1).
