Abstract: A mechanism for winding a ribbon on a take-up spool effects a constant winding rate as the diameter of the wound ribbon on the spool increases. A wrap spring intermittently drives a gear which rotates the spool in a stepwise fashion, the free end of the wrap spring being reciprocated by the stroke of an actuating arm. The amount of ribbon which is wound on the spool is sensed by a diameter sensor, which sensor controls the point on the free end of the wrap spring which is contacted by the actuating arm.

Abstract: An improved dual-seal, wide-surface roller-type dispensing package combination for cosmetics and the like. A wide-surface dispensing roller is held in place in a fitment which is adapted to be attached to the finish portion of a container for the product to be dispensed. The dispensing roller is allowed to revolve within the fitment to facilitate uniform dispensing and application of the contents of the container.

Abstract: A continuous ribbon of moldable material is fed from a plasticizing mill through a stamping section of a molding machine and is returned to the mill as mill stock. The ribbon of moldable material is carried through the stamping section by an endless chain conveyor having prongs spaced therealong. The prongs are pressed into the ribbon as it is drawn from the plasticizing mill. Then, the ribbon is supported by trays as it is drawn along a feed path through the stamping section. The prongs are pulled from the ribbon once the ribbon has been directed by the conveyor back toward the plasticizing mill.At the stamping section, bites are taken from the edge of the ribbon by a die to provide blanks of molding stock to the molding machine. The ribbon is guided by edge guides along a transversely movable supporting tray. The chain conveyor rides in a trough adjacent the tray. By moving the tray and trough away from the stamping die, the mill may be operated continuously even with the mold shut down.

Abstract: For convenience in handling, etc., use is made of a concrete or similarly fabricated member which, although actually a single rectangular block-like member, has a surface line impression effectively simulating a selected arrangement of plural individual pavers or bricks, thereby giving the desirable impression that the construction is formed by said individual bricks, rather than by the fewer number of construction blocks. In accordance with the present invention, the line-forming means, which simulates the individual bricks, is retracted from its position impressed into the concrete mass or mixture through slots in a press-plate having wiping surfaces which removes any adhering concrete therefrom, and thus the shaping contour of said line-forming means is properly preserved for succeeding brick-simulating service. The term "brick" as used herein is intended to broadly encompass regular as well as irregular shapes, such as stones.
