Abstract: A duster holder includes a base board, an overlying board shorter than the base board fixed on the upper portion of the base board, a receptacle formed on the lowest edge of the base board, and a duster inserted in between the overlying board and the base board having feathers protruding from several openings or windows formed on the overlying board to mimic the hat, skirt and other decorative accessories of a human or animal figure printed on the overlying board and base board to thereby form a duster holder for holding the duster therein and also simultaneously enhancing a three-dimensional decorative function of the figures as effected by the duster feathers.

Abstract: An inlet device comprises an inlet chute, an inlet hopper pan and two agitator blades in counter rotation above the flights of a plug screw feeder. The blades are housed in a pan which sealingly connects to a cast plug screw liner which is a U-shaped trough for the plug screw. The agitator blades are driven by shafts supported in pillow block bearings fastened to a main housing. The main housing holds a gear train driven by a right angle gearmotor. The gearmotor is also mounted on the main housing and drives abutting geats in counter rotation above the flights of the plug screw. A storage bin, reservoir, worm conveyor or some type of pulsating feeding arrangement feeds directly into the instant inlet device. The inlet device then feeds into line operations, e.g., a pulp refiner line operation.

Abstract: The present invention relates to an apparatus for producing molding or impression materials, particularly for dental use, by mixing dry powder and liquid in a container mounted on a rotary arm being driven by two pair of gears, connecting the motor shaft of the driving motor to the rotatable container.

Abstract: A lightweight, upright, top-loading vacuum cleaner wherein a seal between the disk of a filter bag and a duct for conveying dirt-laden air to the bag is provided adjacent the outer peripheral edges of the disk resulting in the disk becoming an integral part of the seal while eliminating pressure differential across opposite sides of the disk. A portion of the duct extending into the filter bag is capable of being displaced to an open position for filter bag loading and unloading and is normally closed to maintain the seal by a latch which cooperates with the handle vacuum cleaner handle. The vacuum cleaner handle includes electrical components having projections which are releasably received and supported within an electrical receptacle supported by the vacuum cleaner housing.

Abstract: Apparatus for cleaning reels comprises a set of vats mounted in tandem provided with a track over which reels may be rolled successively through the vats. An endless conveyor extends along the series of vats from which resilient grab arms are pivotably suspended. The arms are provided with sockets to capture opposite ends of the reel axles. Cam rods are provided for guiding the sockets into and out of positions of axial alignment with the reel axles to effect reel pickup and release.

Abstract: An agitator of impeller shape includes an agitator hub with a plurality of radially extending arms for attachment to a drive shaft for the mixing of substances in vessels, such as substances that tend to material build-up, incrustation and/or incipient polymerization. The hub is totally closed by welding a cap over the end of the hub. At least one of the agitator arms is formed of two components, a shorter stub arm attached to the hub and longer main arm. Both components are formed of a pair of parallel, spaced apart tubes connected by a pair of webs. Each tube includes a bushing for retaining a centering bolt to attach the main portion to the stub portion. The two components are then welded together and polished to remove any gaps and sharp edges.

Abstract: The squeegee device is for cleaning both flat and curved surfaces. It has a handle and a squeegee blade assembly mounted together by a rigid coupling bracket to form a rugged joint. The handle can be positioned in one of at least four positions relative to the blade assembly to facilitate either a push and pull cleaning operation or a side-by-side sweeping cleaning operation.

Abstract: Narrow strips of trim waste from high speed paper web converting and winding operations are drawn into a vacuum disposal system by a receiver which draws the trim strip over a flat surface aligned substantially parallel-planar with the strip off-running course. Such flat surface is flushed with an attached boundary layer of high velocity air which follows a smooth curve of the flat surface into the duct wall enclosure.

Abstract: An elongated film strip is cleaned by two pairs of rotary brushes with soft bristles contacting opposite sides of the film strip traveling between the two pairs of brushes. Each pair of brushes is placed at an angle to the direction of film travel for brushing dirt particles away from the center of the film. The top pair of brushes and the bottom pair of brushes are arranged so that one brush in each pair brushes the particles from the central region of the film toward one edge of the film, while the other brush on the same side of the film brushes particles away from the central region of the film toward the other edge of the film. The brushes avoid contact with perforations on the edge of the film which would result in particles lodged in the perforations being brushed toward the central region of the film. A separately electrically conductive vacuum tube contacts each brush after the brush contacts the film.
