Abstract: Systems, methods, and computer-readable media are disclosed for automated sweepers for item sortation systems. In one embodiment, an example item sortation system may include an aisle, a number of chutes accessible from the aisle, a shuttle configured to transport first items from an induction portion of the item sortation system to a first chute of the plurality of chutes, and a robotic sweeping system disposed in the aisle. The robotic sweeping system may be configured to sweep second items on a floor of the aisle to a first end of the item sortation system. The robotic sweeping system may include a motor and a sweeping device.

Abstract: In a wheel supported floor and carpet push brush of the type having an array of aggressive bristles and another array of bristles which are of lesser diameter than the aggressive bristles carried on the dowel so that the brush can be turned over to bring a selected one of the arrays into operative sweeping position, the improvement wherein the average diameter of the aggressive bristles is no greater than about 0.012 inches with a preferred diameter being about 0.010 inches, and the other array of bristles have an average maximum diameter less than 0.010 inches with a preferred diameter being about 0.008 inches.

Abstract: The invention relates to a carpet-cleaning brush, in particular for cleaning rugs or carpets, which have been soiled by the hair of animals kept in the room. Said brush has bristles (3) in the form of an angle of arc, a brush body (2) for receiving said bristles, a brush head (1) which is fixed thereto and provided with a handle, in addition to a dust-collector head (7) which preferably contains a suction connection (72). The invention is characterized in that the brush body (2) is a rubber plate, pierced by the limbs of elastic, U-shaped metal wire bristles (3) which are fixed on an inclined plane in the direction of pull of the brush. Said bristles form an angle of 5-15° (&agr;) in relation to the plane, which is perpendicular to the plane of the brush body. The limbs which form part of the U-shaped bristles (3) are provided with a plastic coating (4) or similar, at least on the free, protruding ends.

Abstract: An uncoated titanium-based carbonitride cutting tool insert with superior plastic deformation resistance and wear resistance is provided. This is accomplished by heat treating the material in nitrogen atmosphere under conditions to obtain a nitrogen rich surface zone, also containing substantial amounts of binder phase.

Abstract: A desk top cleaner for cleaning dust from the top of a table includes a crankshaft rotatably supported in a frame. A broom is formed with an elongated slot to engage with the crankshaft and has its upper end portion fitted in a supporting portion formed in the frame and its lower end portion equipped with a brush. A drive mechanism is provided for transmitting a rotating force from a drive source to the crankshaft. A dust case for accommodating the dust swept by the broom is included in the frame.

Abstract: A carpet sweeper for removing metallic staples, paper clips and the like from carpet wherein a semi-circular wire mesh fabric is secured to the forward end of a housing or base member and a magnet is secured to the bottom of the base member and extends along the trailing edge of the wire mesh fabric. The wire mesh fabric dislodges the metallic fasteners from the carpet and the magnet attracts and accumulates the dislodged fasteners. A scraper is removably mounted on the housing for removing the accumulated fasteners from the surface of the magnet, and a rod having a slotted magnetic end is provided for manually removing deeply embedded metallic fasteners from the carpet.

Abstract: A manually operated cleaner is provided with a body in the form of a box-shaped container having a removable lid and a bottom wall. Two parallel openings are provided through the bottom wall of the container. A roll brush is mounted to project out of one opening and a rotatable semicylindrical brush body is mounted for pivotable movement between two stop members with one of its surfaces including inclined bristles projecting through the other opening. A dust removing brush member having bristles inclined toward the interior of the container is pivotably mounted to the container and urged by spring means to maintain sliding contact with the bristles on the brush body.

Abstract: An apparatus for loosening-up the walked-down nap of a carpet has a carrier that rides on rollers on the carpet and which is provided with a pair of brushes spaced apart in the displacement direction. Each brush has an elastic bed for a multiplicity of wire bristles with bent-over ends that engage in and loosen up the carpet nap. The brushes may be cylindrical and driven by a motor on the carrier which also drives the rollers. The trailing brush engages more deeply in the carpet nap than the leading brush.
