摘要： Coupling device for conduits for pressurized media which consists of at least two coupling parts (1, 2) which are possible to couple to each other in the shape of a female part and a male part which is insertable into the female part. A locking device is arranged to hold the coupling parts completely coupled in a locking position. The locking device comprises a locking organ (11) positioned at one of the coupling parts (2) which in a locking position attaches into a recess (12) in the other coupling part. A sealing organ (6) in the locking position achieves sealing between the coupling parts. The other coupling part (1) exhibits a further recess (16) in which the locking organ can be brought to locking of the coupling parts (1, 2) in an outer locking position when the two coupling parts are coupled to each other. In the outer locking position there is incomplete sealing with the two coupling parts being locked so that they are prevented from coming apart but are incompletely coupled together and allowed to be brought together to said locking position for the complete coupling of the coupling parts. In the presence of pressurized media this enables an indication that the outer locking position has been assumed due to the presence of leakage of pressurized media. The leakage is obtained via a leakage groove (20) which is angled towards the radial plane of the coupling parts. The leakage groove can thus be made by means of rotating machining.

摘要： The invention discloses a method for use in a wireless communications system with a plurality of broadcasting nodes, comprising the step of enabling one node in the system to function as a central node in said system and letting said node enable measurements on at least one frequency in a frequency band used by the system. Said measurements are carried out to detect if said at least one frequency is being utilized by a transmitter foreign to the system. Preferably, the measurement is enabled by means of the node transmitting a message to other nodes in the system, said message being a message pre-defined within the system as a message prohibiting all nodes from transmitting during a certain interval, said message being transmitted after the system has been detected by the node to be silent during a predefined interval between frame transmissions from the nodes in the system.
