Abstract: A programmed actuation and an accurate stoppage of a mechanism in a predemined position after performance of a predetermined number of revolutions is achieved by provision of a main shaft driven through a claw clutch and of an auxiliary shaft driven from the main shaft through a transmission, the auxiliary shaft having actuating means for disconnecting the claw clutch after a number of revolutions of the main shaft determined by the transmission ratio of both shafts.

Abstract: A tangle composed of the end of a guiding rope and of a wire is formed and driven into the soil by a device which forms this tangle by subsequent operations and drives it into the soil.

Abstract: Method of and apparatus for preparing weft supply in a magazine for weft insertion in shuttleless looms, particularly looms with pneumatic or hydraulic weft insertion. The yarn path is prolonged by the action of an air flow in the magazine, into which the weft is continuously fed upon being withdrawn from a supply bobbin. The weft is withdrawn from the magazine in weft inserting intervals in a length sufficient for one pick. The inside of the magazine is constituted to produce a helical air flow which directs the fed weft into a spatial spiral or helox, from which the inserting length is axially withdrawn.
