Abstract: An improvement to a hopper to promote the flow of solid particulate material includes mounting one or more walls of the hopper for limited oscillatory motion in a direction parallel to the wall and perpendicular to the desired flow direction, and then providing an actuator connected to the remainder of the hopper to impart such motion to the wall. The relative motion between the moving wall and the particulate material effectively rotates the friction force to the direction of relative motion, leaving the friction in the desired flow direction approaching zero. As a result, downward flow can occur on walls that are only shallowly inclined. The improvement is applicable to hopper-like structures in railroad cars and ships, where it facilitates discharge onto moving conveyors.

Abstract: A continuous web of wrapping material for catamenial tampons or other commodities is advanced lengthwise first through a station where it is acted upon by a perforating knife to weaken longitudinally spaced-apart portions of the web transversely of the direction of advancement. The web is thereupon converted into a continuous tubular body and the leader of the tubular body is engaged by a pair of rolls which pull the leader in the direction of lengthwise advancement of the web in order to break the material of the web along successive weakened portions. The thus obtained discrete tubular envelopes are moved sideways, one end portion of each envelope is closed, a commodity is introduced through the other end portion, and the other end portion is closed to confine the commodity at both ends. Such mode of making tubular envelopes ensures that the material of the web is not wasted at all and that the envelopes need not be stored prior to reception of commodities.

Abstract: A device for promoting gravity flow of zirconium tetrachloride and other non-free-flowing solids has a rotatable shaft. At least two flexible lengths have first ends attached to and axially spaced on the shaft and also distal second ends. A collar is slidably mounted on the shaft between the spaced first ends of the flexible lengths for slidable axial and circumferential movement on the shaft. At least one sweep arm has a first end pivotally attached to the collar and a second distal end attached to the second distal ends of the flexible lengths. The collar slides relative to the shaft as the sweep arm encounters resistance from bridged solids. The relative movement of the collar and shaft causes the flexible lengths to wrap around the shaft and the arms to collapse toward the shaft. A device with collapsible arms will have a minimal torque requirement. When the solids dislodge from the collapsed sweep arms, the arms extend to sweep outwardly to a maximum extent.
