Abstract: A pulley drive system utilizes a driven pulley and a driving pulley and a belt connecting the pulleys. The driving pulley has spaced discs and there are means for varying the spacing between the discs to vary the speed of the belt driving the driven pulley. Speed sensing means are positioned adjacent the driven pulley to provide a signal representative of the speed of the driven pulley. The speed sensing signal is utilized in a regulating circuit to control the means for varying the spacing between the discs to thus control the speed of the belt.

Abstract: A bridge for supporting a dispersing impeller and drive shaft with the bridge being formed primarily of a single sheet of steel plate bent so as to form a hollow rectangular cross-section. The impeller shaft is mounted by bearings attached to the upper and lower walls of the bridge, for pedestal mounting of the bridge or for being supported directly on the dispersing container.

Abstract: A chain is trained around two substantially coaxial sprockets. A chain fastener comprises two fastener members connected to respective ends of the chain and a locking pin adapted to assume a first position, in which the locking pin locks the two fastener members together, and a second position, in which the locking pin permits the two fastener members to be separated from each other. The locking pin is movable between the first and second positions in a plane which is normal to the axis of the sprockets.

Abstract: A friction disc is described for very quietly driving twist tubes at several hundred thousand revolutions per minute in a false-twist device for texturing synthetic filaments. The disc has a titanium alloy support flange having a specific electrical resistance of between 1 and 2 .OMEGA./mm.sup.2 /m, a modulus of elasticity of at least 6500 kg/mm.sup.2 and an ultimate tensile strength of at least 25 kg/mm.sup.2. The support flange has a circular cylindrical circumferential surface which fits and is rigidly fixed to the internal surface of a polyurethane friction ring, the external cylindrical surface of which frictionally drives the twist tube. A twist tube driving roller has two such discs spaced apart on a steel driving shaft.

Abstract: A bull wheel is disclosed for applying a tensioning or retarding force to cable. The bull wheel has a center drum having a peripheral rim. A series of groove defining segments of resilient material are detachably secured to the rim to form the traction wheel for convenient assembly and repair. In one embodiment the segments are curved and define a single groove. In another embodiment the segments are flat and define multiple grooves and are wrapped at assembly to conform to the curvature of the bull wheel rim.

Abstract: A rotary motion transmitting device including traction rollers for transmitting motion in either direction from an input shaft to an output shaft. One shaft carries an internal traction ring and the other shaft, whose axis is parallel to, but slightly spaced from, the traction ring shaft, extends into the traction ring and carries an inner roller to form a varying annular space. Three intermediate traction rollers are angularly disposed within this annular space and are urged into firm Hertzian contact with both the traction ring and the inner roller by means of the torque transmitted through the device. The five traction rollers have a sum of degrees of freedom of movement in a plane perpendicular to the axes of the rollers equal to 8, 9 or 10.

Abstract: An apparatus for transmitting torque to a load includes a pair of pulleys vertically spaced apart by a great distance for movably mounting a long endless belt in a substantially vertical disposition to move it freely in a closed loop path, a plurality of spaced-apart arm devices connected to and extending from the belt, and a plurality of weights adapted to be carried by the arm devices. The weights and the arm devices are arranged in pairs, and each one of the pairs provides a larger moment acting through the belt on at least one of the pulleys when falling vertically downwardly under the force of gravity and alternately provides a relatively smaller opposing moment acting through the belt on at least one of the pulleys when being pulled vertically upwardly by the belt, whereby torque may be transmitted from at least one of the pulleys for driving the load.

Abstract: A drive system comprising a prime mover such as an engine providing a drive shaft, a shell supported by the shaft for rotation relative to the shaft, a split groove pulley mounted on the shaft, the pulley including one flange secured to the shaft for rotation therewith and a complementary flange connected to the shell for rotation therewith, the flanges defining a space axially therebetween, an adjustably movable take-up pulley having a belt-tightening position and a belt-loosening position, and a belt trained about the pulleys. When the belt is tightened by the take-up pulley, the shell and complementary flange rotate with the shaft and the said one flange, i.e., the belt provides a driving connection between the two flanges. When the belt is loosened, the driving connection is broken such that the one flange and shaft rotate relative to the complementary flange and the shell.
