Filed: 1988-03-21
Granted: 1990-03-14
Abstract: The invention is a method for cleaning up contaminated soil containing not only different types of hydrocarbons but also heavy metals and cyanades which upon heating of the soil can form dioxin and benzofuran products. According to the invention the production of said products is prevented by keeping the wall temperature of the rotating furnace at a high level such that its temperature during the entire process is higher than the temperature of spontaneous combustion of the pyrolyses products of which at least the hydrocarbons bind the oxygen in the furnace. The oxygen content may be further influenced by the infeed of an inert gas and/or by adding an organic fraction such as humus.

Abstract: A flexible multiplexer comprises terminal units each with a communications control unit. These are interconnected via a three-conductor system for transmitting internal data to a controller and for receiving internal data and control signals therefrom. It is intended to increase the number of communications control units which can be driven by the controller. The multiplexer is divided into a main unit carrier (MMOF) with terminal units (TA1, TA2) on the participants' side and/or terminal units (LA) on the conductor side and with the controller (CTR) and into several extension unit carriers (EMOF) with terminal units (TA1', TA2) on the participants' side and/or terminal units (LA) on the conductor side and with a system extension unit (SEU). Each unit carrier (MMOF, EMOF) has its own three-conductor system (L, L'). A four-wire system (V, V') is connected on one side to a communications control unit (HSCX3) of the controller (CTR) and on the other via conversion units (U, U') to the three-conductor system (L, L'). Dialogue is possible between the controller (CTR) and each terminal unit (TA1, TA2, TA1', TA2', LA and LA'). The controller bus system is suitable for flexible multiplexers with a large number of terminal units.

Abstract: In a computer network, a broker mechanism allocates a plurality of servers, each having an available resource capacity, to a plurality of clients for delivering one of several services to the clients. The broker operates by monitoring a subset of all available servers capable of delivering the requested service. The allocation is based on developing a network policy for the plurality of servers by collecting a local policy for each of the servers. The broker receives client requests for the services and based on the network policy and available resource capacity suggests one of the servers, monitors in its subset for that particular service, to one of the clients making a request. The server suggested enforces its local policy by not allowing any connections exceeding its available resource capacity.

Abstract: At the beginning of an address operation for a request to be executed, an identification code (TID) is generated and transmitted with the applied address (ADR) from the requesting subscriber (for example TN1) to all other subscribers via the line system (SPBUS). Each subscriber, even the transmitter itself, is provided with storage devices (BUFM,SYNC-QU) for accommodating the address transmitted in each case and the request identification code (TID) also supplied. At the same time, the addresses stored in the storage devices (SYNC-QU) are monitored in checking devices (for example CCAE-CTR) of the subscribers for assigning the line system (SPBUS) for further transmissions, and after all subscribers have been monitored, a synchronisation signal (SYNC) and, if necessary accompanying signals (SHA,INT,ABORT,ACT) are set for ending or continuing a request. When they are continued with a data operation, a correlation of the data operation with its corresponding address operation can be achieved by transmitting back the associated request identification code (TID) together with the data (DATA) to the requesting subscriber, which correlation allows data responses to occur outside the order defined by the initialisation of the individual address operations. <IMAGE>
