Inventor: BIELEFELDT ERNST-AUGUST DIPL-I
IPC: B01D53/24
Filed: 1987-04-30
Abstract: The invention relates to a process for isolating and/or separating solid and/or liquid particles (disperse phase) from gaseous and/or liquid media (continuous phase) and for separating mixed gases (gas-gas separation) and/or mixed liquids (liquid-liquid separation) and for sifting and/or classifying using a cyclone separator having a dip pipe 35. To reduce the flow losses in the introduction of spin, the contact zone between the main flow and the vortex is adjusted to the fixed cylinder casing boundary in such a manner that the tangential entry momentum into the bottom layer flow is increased by reducing the secondarily circulating momentum fraction of the bottom layer flow in the cyclone chamber. To reduce the momentum mixing losses by dissipative pressure loss in the flow in the main channel, the bottom layer flow is designed to be rotationally symmetric at constant or approximately constant mean main flow velocity. The clean gas flow is conducted through dip pipes 35, having cross-sectional areas enlarging towards the outlet, in such a manner that in the zones of the highest flow velocity, the flow is only loaded by weak meridional flow deflections. The clean gas flow is conducted on the outer wall of the dip pipes with velocity increasing towards the intake sections. <IMAGE>

Abstract: A protocol analyzer is provided for monitoring a selected communication connection being conducted in accordance with a predetermined protocol by the exchange of protocol data units between two entities over a data network (12). The analyzer (10) comprises monitoring means (13-15) for identifying protocol data units, a protocol-follower (17,18,27) conditioned in dependence on said predetermined protocol and operative to follow the progress of the connection as it receives relevant protocol data units from the monitoring means (13-15), and alarm means (22) indicating when the sequence of protocol data units diverges from the protocol. The protocol data units are passed through a FIFO store (16) as they are used by the protocol-follower, so that on a protocol violation occurring, the sequence of protocol data units leading up to the violation can be extracted from the FIFO store (16) and displayed. The protocol analyzer thus filters out protocol data units conforming to the relevant protocol so that only protocol data units violating the protocol, together with the immediately preceding protocol data units, are displayed.
