Abstract: An apparatus for suspending at least one current-carrying contact wire for current collectors of overhead line buses or trams comprises a connecting element is fixed to a support cable. The connecting element is formed from an insulating plastic material, preferably a glass fiber-reinforced polyamide, and forms a unitary shaped body having a receiving member for a support element which is adjustable relative thereto, for supporting the gripping member. The connecting element includes a support shoe with connection eye for an insert which can be fixed therein, for receiving the support element in a pivotable manner and a clamping cover which can be screwed to the support shoe. The support shoe and clamping cover are provided with a longitudinal groove for receiving the support cable in a non-slip fashion.

Abstract: A device to monitor a moving yarn for irregularities is described. A first sensor head (2) with a recess (6) and a second sensor head (3) with a recess (7) are arranged in the direction of yarn movement. The cross-sectional depth of the recess (7) in second sensor head (3) is deeper than that of the recess (6) of sensor head (2). It is therefore possible, for example, to record separately slubs and projecting fibers. The monitoring device can be automated and used for quality control of any type of yarn.
