Abstract: The invention relates to apparatus and method for producing a wrap-around yarn of the type having an untwisted core thread with a binder thread helically wrapped around the core thread wherein the core thread is given a false twist and the core thread and binder thread are passed through separate openings through a hollow spindle to a core thread deflection point at which time the false twist is removed from the core thread and at which point the binder thread is wrapped helically around the core thread.

Abstract: A paver attachment is illustrated for connecting a paver to a dump truck and the like having an elongated longitudinally disposed arm assembly carried on one end by the paver for raising and lowering the free end thereof to which is attached securement means for engagement with the dump truck adjacent the transmission to provide a fixed distance therebetween and to permit independent maneuvering of the paver as around curves.

Abstract: A method and apparatus for detecting the faulty working of spinning units of an open-end spinning machine by monitoring the faults in yarn as it is fed from the spinning machine. An electrical signal is produced by a sensor indicating faults appearing in the yarn. Another signal of predetermined frequency corresponding to the speed of delivery of the yarn from the spinning machines is generated. The electrical signal produced by the sensor is electrically multiplied by the signal of predetermined frequency for producing a differential signal. This differential signal is filtered, shaped and integrated and subsequently compared with a preset threshold value for producing a signal indicating when the occurrence of faults exceed a predetermined threshold. This signal can be used for stopping the spinning unit.

Abstract: An asphalt paving planer is illustrated wherein a power operated conveyor is mounted ahead of a cutter drum for receiving asphalt cuttings and conveying them to a truck and the like driving in the forward direction in front of the paver, and wherein a cutter drum drive is provided which includes an internal combustion engine for driving a V-belt drive which, in turn, drives a gear reducer carried adjacent the cutter drum.

Abstract: A stop motion apparatus is disclosed for disengaging a drive motion on a carding machine in response to the detection of a desired operating condition wherein the carding machine is of the type having motorized drive means for imparting a drive motion to the carding machine when engaged and actuator means for selectively enaging or disengaging the drive motion. The stop motion apparatus includes a base for attachment to the carding machine and a pivotable arm assembly carried by the base. A linkage assembly connects the pivotable arm assembly to the actuator means of the carding machine. The pivotable arm assembly has a first position in which the actuator means disengages the drive stopping the carding machine and a second position in which the actuator means engages the card drive.

Abstract: An apparatus for bringing to rest the rotor of an open-end spinning apparatus which is covered by a cover. The rotor is mounted in a wedge gap formed by freely rotatably support rollers and pressed against the support rollers and driven by a tangential belt. An axial force arising from the support rollers presses the rotor against an axial stop. A lever is provided for lifting the shaft off of the support rollers and against stops for arresting the rotation of the rotor. Compressed air is applied to the rotor when the rotor is being brought to rest for maintaining the shaft of the rotor against the axial stop.

Abstract: A fishing lure comprising a body of buoyant material which has an elongated hole extending into the front head portion thereof. The elongated hole is defined by walls which intersect each other at sharp angles. A lip member is inserted by means of an elongated shank portion within the elongated hole. The elongated shank portion has surfaces intersecting each other at complementary angles to the sharp edges of the elongated hole so as to prevent the shank portion from turning in the hole. An elongated screw member extends through the body of the lure and the shank portion for securing the lip member in the body. The lip member can be readily interchanged by removing the screw so as to affect the depth that the lure dives when fished.
