摘要： A method and apparatus applicable to digital transmission by microwave beams. The method and apparatus serving to synchronize two binary trains (T1, T2) in order to switch from the first train to the second, with a synchronization range being used which extends between a first position in a buffer memory storing the train which is directed to the output and for which reading follows writing by one bit period (case A), to a second position where reading precedes writing by one bit period (case B).

摘要： The invention relates to apparatus for providing protection against insects. The apparatus comprises a support device (10), a framework (20) carried by the support device, and netting carried by the framework for the purpose of surrounding a protected zone. The framework comprises a central pivot (22) about which a plurality of arms are capable of pivoting about practically the same axis, said axis being designed to be substantially vertical. The arms (24, 26) can pivot about said axis between a working position in which they are distributed around the axis and a rest position in which they are all placed on the same side of a vertical plane including the pivot. The invention is applicable to mosquito nets.
