  • Publication number: 20240154821
    Abstract: Embodiments of the invention relate to a distributed network which comprises a replicated computing cluster. The replicated computing cluster comprises a plurality of nodes, wherein each of the plurality of nodes of the replicated computing cluster is configured to run a replica and each of the replicas is configured to run one or more computational units. The replicated computing cluster is configured to perform consecutive consensus rounds to reach a consensus on a sequence of payloads and to perform consecutive processing rounds comprising a consecutive processing of the sequence of payloads in a deterministic and replicated manner. The replicated computing cluster is further configured to perform consecutive computations of a random seed for each of the payloads of the sequence of payloads and to use the random seed of a respective payload of the sequence of payloads to provide randomness to the payload.

  • Patent number: 4592803
    Abstract: The disclosure relates to a process for making alkali metal phosphates, especially alkali metal polyphosphates, from alkali metal phosphate solutions or suspensions. To this end the solutions or suspensions are forced to flow through a plurality of single opening nozzle structures under a pressure of 6 to 66 bars and sprayed inside a tower through a flame zone produced by a plurality of burners arranged in annular fashion. The disclosure also relates to a device for carrying out the process, wherein a cylindrical spray tower (1) having a tapered lower end and being closed by means of a cover (2) has a solvent feed pipe (5) terminating in a spray means (6) centrally passed through the cover, and wherein a plurality of burners is passed through the cover (2), concentrically around the solvent feed pipe (5). The spray means (6) is comprised of a feed pipe (15) and at least one spray head (12), which has a plurality of single opening nozzle structures (17) disposed in its terminal surface area (13).
