  • Patent number: 5654969
    Abstract: In a communications network, first information items are transmitted synchronously and second information items asynchronously. The second information items are overlaid on the synchronously transmitted first information items. A bandwidth accessible on transmission can be variably distributed between the first and second information items and, with the desired variable distribution, transmitting and receiving units become synchronized by synchronization information which is transmitted via a channel established for asynchronous transmission between the transmitting and receiving units.

  • Patent number: 4004650
    Abstract: The invention relates to silencers for damping sound waves created in gases, comprising a series of thin-walled, tubular damping units and an inner tube for conducting gases through the end walls of the units, the tube having openings communicating with the chambers defined in each unit. In accordance with the invention each damping unit is surrounded by an outer tube which is connected in a gas-tight fashion through two end walls with the cylindrical surface of the damping unit, and the space between the cylindrical surface and the outer tube is divided into at least two chambers communicating with the inner tube through a transversely-extending branch pipe.
