    摘要： A butterfly net is disclosed comprising a stocking cap-shaped netting open at one end thereof. The netting has a hem-line loop formed along the periphery of the open end. A flexible strip of finite length has one portion thereof threaded through the loop, and a second portion thereof extending outside the loop. The butterfly net is provided with an elongated handle member having a longitudinally extending opening. Guide means are provided adjacent the opening for guiding the second portion of the strip into the opening. An actuator is slidably mounted on the handle member, and is coupled to the second portion of the strip. The actuator is movable on the handle between a first position in which the one portion is of one length and the open end of the netting is fully opened, and a second position in which the one portion is of a smaller length and the open end of the netting is at least partially closed for capturing a butterfly.

    摘要： In a telecommunication system with a number of units (Ula-Una, Ulb-Unb) for control purposes and also for subscriber facilities, each such unit is duplicated, as is the system controller (SCa, Scb). There are two local area networks (1,3), each of which interconnects one system controller and one unit of each pair of units. When one network is to be isolated, e.g. for servicing or when a fault occurs, its controller detects that condition, and isolates that network by relay circuitry in the termination (T2, T3) of the bus. Another version of the system uses local area networks of the closed ring type. In certain cases the units, etc., may be triplicated.
