摘要： The present disclosure relates to a device for unstowing an electrical supply cable from a storage chamber disposed within an underground service pit. The cable is configured to electrically connect to an electrical power supply at a first end and to connect to an external power socket of an aircraft at a second end for supplying electrical power to the aircraft. The device includes a cable guiding wheel that is disposed at ground level above the underground service pit and configured to receive the cable. The device also includes a motor coupled to the cable guiding wheel that is configured to drive the cable guiding wheel. Upon activation, the motor rotates the cable guiding wheel to generate a pulling force on the cable to at least partially lift the cable out of the storage chamber.

摘要： A portable rope drive and guiding apparatus operable by a single user is disclosed. The apparatus includes a receptacle defined by a first side wall, a second side wall, a first end wall and a second end wall, with a vertical opening between a top edge and a bottom edge for receiving the rope. The apparatus further includes a powered drive wheel mounted between the first side wall and the second side wall, and having a friction-bearing outer perimeter to drive the rope through the receptacle. The apparatus further include a guide wheel mounted between the first side wall and the second side wall, opposite the drive wheel, the guide wheel having a concave outer perimeter that corresponds to and guides the rope through the receptacle as the rope is driven by the drive wheel.

摘要： A method of feeding a wire with a drive roller comprises guiding a bent wire into a guide groove of the driver roller at an angle of at least 0.5° relative to a tangent to the circumference of the drive roller at the entry point of the wire into the guide groove. The wire is pressed into the guide groove, bending the wire during pressing and engaging the wire with the guide groove. The engagement between the wire and the guide groove is maintained along a portion of the groove which is equal at least one diameter of the wire and is no longer than the length of the guide groove. The method further comprises guiding the sire away from the drive roller and straightening the wire by contraflexing it at an angle of at least 0.5° relative to a tangent to the circumference of the drive roller at the exit point. A device for feeding a wire has a drive roller with a guide groove, a guiding mechanism, a straightening mechanism and an engaging device and a pressing-in joint of the wire into the guide groove with at least two pressing-in components. The advantage of the method and device is in achieving higher pushing forces for guiding the wires over long distances, as well as high quality straightening of the wire.

摘要： The invention pertains to a tension regulator for elastic tape and the like, particularly in sewing machines adapted to attach tape to a workpiece.This regulator substantially consists of an electromechanical transducer on which the stress produced by tensioning the tape causes a mechanical deformation converted into an electrical signal; this electrical signal, suitably processed, controls a motor means which acts so as to feed or take up tape in order to keep the tension of the same at a constant value.

摘要： A weft tensioning device in a shuttleless loom includes a weft yarn feeder and a tension compensator interposed between the weft yarn feeder and a filling carrier. The tension compensator has a pair of weft guides and means disposed between the weft guides for intermittently shifting the weft yarn sideways off a path between the weft guides in response to reciprocation of the filling carrier. The weft yarn feeder has weft yarn winding means, the diameter of which is variable to meet different yarn demands for various widths of narrow fabric to be produced or to compensate for varying yarn stretchability due to different degrees of ambient temperature and humidity.

摘要： In a winding machine having independent spindles with a grooved yarn-guide driving bobbins preventing winding irregularities, winding bobbins at high speeds from conventional or sectional hanks, cops, cakes or the like, namely winding machines having a conical bobbin which rests on a cylindrical yarn-guide having helical grooves generally with two opposing pitches which distributes the yarn uniformly on the bobbin, the latter resting under its own weight above the yarn-guide which drives the bobbin by frictional resistance, the axis of the bobbin moving progressively away from that of the yarn-guide as the yarn is being wound while forming normally in a plane common to the two axes a small or zero angle with the axis of the cylindrical yarn-guide, including a device for preventing the yarn from collecting at certain preferential points of the bobbin at certain winding speeds, and including a yarn break detector, the improvement comprising a device for oscillating at least one of the ends of the shaft of the yarn-guide and of the bobbin with an alternating relative oscillatory movement substantially perpendicular to a plane defined by the axes of the bobbin and of the yarn-guide, when they are in this plane, without causing any substantial vertical oscillation of the bobbin. A modulated action device accompanies the oscillation of the yarn-guide or of the bobbin for retaining the yarn in a groove of the yarn-guide for any operative position of the axis of the yarn-guide with respect to the axis of the bobbin. The modulated action device is combined with a device for preventing a faulty movement of the yarn with respect to the axis of the bobbin both at a time of starting and at a time of braking, comprising a torque converter for providing a uniform and moderate torque on the yarn-guide at the time of starting, an automatic braking device for intensive simultaneous stopping of the control motor, of the bobbin, and of the yarn-guide and the members which actuate it as soon as an exaggerated traction is exerted by the yarn which is supplied, the automatic braking device braking the bobbin abruptly and with priority, and a device for tensioning the feed yarn for preventing slipping thereof.
