Date Jun. 15, 1989.The invention concerns a method for the preparation of moulds and cores used in the casting of metals. In the method the moulds and cores are prepared out of a granular moulding material as well as out of a binder agent that binds the moulding-material granules together. The binder agent used for the moulding mix is an anorganic salt, sodium aluminate, soluble in water and having a high melting point, as a rule higher than the casting temperature, which said salt is mixed with the granular moulding material as binder-agent solution dissolved in water. In the moulding process the binder agent is crystallized out of its water solution by microwave energy so that the binder agent forms a solid bridge between the granules of moulding material, said bridge binding the granules of moulding material together. The combination formed by the binder agent and the moulding material is chosen so that the binder agent and the main minerals of the moulding material are chemically unreactive with each other at the moulding and casting temperatures.

Abstract: A network structure and a signalling protocol for a telecommunication network. The nodes of the communication network are interconnected by a connection network as well as a signalling network. Computer software controlling the communication equipment of each node is divided into two types of software, connection related software and service related software. Connection related software groups of different nodes communicate with each other via a first protocol while service related software groups of different nodes communicate via a second protocol different from the first protocol. Between an originating node of a call and the terminating node of the same call a direct signalling path is established in the signalling network allowing for the addition of new service features in the originating and terminating nodes without the need to implement the new service features in the inbetween nodes via which the same call is routed in the connection network. A general signalling protocol supports the addition of new service features to existing nodes as well as the execution and management of the new services and the services already existing in the telecommunication network. The signalling protocol is divided into a basic protocol and one or more service specific protocols called dialogues. The basic protocol is used to establish a signalling path between service related software groups in the originating and terminating nodes and to establish dialogues along the signalling path. This allows for a modular addition/removal of dialogues to the basic protocol which remains unchanged.
