For this purpose, the carbide cutting tip (11) is arranged transversely to the flute runout (12, 13) so that the effective moment of resistance area in the area of the groove root (22) of the recessed groove (14) is not weakened by flute runout surfaces.

Abstract: An automatic powder dispensing and measuring apparatus which automatically and rapidly and accurately delivers a preselected amount of powder such as gun powder to a scale. The powder dispensing apparatus is preferably in the form of screw threaded barrels rotatably driven by an electric motor which pick up powder from a chamber and dispense it from the end of the barrel to a scale. An electronic circuit controls the rotation speed of the screw threaded barrels in response to sensing means which cause no mechanical resistance to scale motion, positioned to sense the weight being measured by the scale. As the scale approaches the precise preselected amount of powder the electronic circuit responds by slowing the rotational rate of at least one of the screw threaded barrels to slow the feed rate and stop the rotation and flow of powder when the weight the scale reaches the precise preselected amount.

The vibrator connected to the container support delivers a vertical component of force that has an especially good and efficient packing reaction on the material in the container.

Abstract: To weigh objects in quick succession, the objects are projected with a known horizontal velocity onto a ramp which has a surface which curves down through 90.degree.. The ramp can move horizontally in response to the impulse corresponding to the change in horizontal momentum of the object. A transducer senses the movement of the ramp and the output horizontal velocity of the object is sensed, enabling the change in horizontal velocity to be calculated. The mass of the object is calculated from the horizontal movement of the ramp and the change in horizontal velocity of the object. In order to obtain accurate sensing of the movement of the ramp, the transducer is a linear variable differential transformer having a primary winding energized by a cyclical carrier signal and two matched secondary windings in series; the secondary winding output signal is rectified to a corresponding DC voltage having ripple components, and a sample is taken of the signal at the zero voltage of the principal ripple component.

Abstract: A bulk conveyor is described, including an elongated belt with means for supporting the belt along its working flight. The working flight support includes a number of cradle members connected in spaced relation along opposed roller chains. The chains are trained about sprockets between end rolls that mount the conveyor belt. The chains and the sprockets rotatably mounting them to the frame permit simultaneous motion of the cradle support members with the belt along the working flight. They also hold the cradle members in proper transverse orientation to the belt length. The cradles are supported along tracks that bear the weight of the cradles and of the load carried on the working flight. Motion of the cradles along the working flight is simultaneous with the belt so there is little frictional sliding engagement between the contacting surfaces of the belt and cradle. The belt leaves contact with the cradles along its return flight and rides over spaced support rolls below the returning cradles.

Abstract: The apparatus comprises a continuous looped belt (10) having an upper run (11) for carrying a load and a return lower run (12). A single cable (100) is arranged over numerous pulleys to define two spaced parallel upper runs of cable (101) and two spaced parallel lower runs of cable (102) which support the belt runs (11, 12). The belt is broader than the spacing between the spaced runs of cable and seats on top of the cable. A cross-over arrangement (110) provides for the cable to form two identical and parallel cable portions defining the cable runs. All pulleys in one portion are mirrored by co-axial pulleys in the other portion, so that, at any point, the tension in one cable portion is equal to that in the other portion. A double drive roller arrangement reduces scuffing of the cable, so that the whole system substantially reduces wear of the cable.

Abstract: An anti-toggling, constant-contact cage roll assembly is provided for movement of corrugated box blanks along a belt. In one embodiment, the cage roll assembly includes a series of four rollers that are mounted to a bar spring-biased away from a frame, in which the bar is pivotally mounted at each end to an associated lever arm, each of which is in turn pivotally mounted to the frame to form a modified four-bar linkage, with a compliant mount for one lever arm, the mount for the other lever arm being fixed to the frame to permit limited canting of the roller-carrying bar to accommodate multiple folded layers of corrugated material. The subject cage roll assembly prevents the prior art type of toggling of pairs of rollers into an almost vertical position as the box blank moves between the rollers and the belt and thus prevents jamming. In one embodiment, each of the lever arms carries an adjustable stop at the free end for positioning the bar above the belt which carries the box blank.
