Abstract: A machine has a frame on which is mounted a conveyor mechanism including two vertically spaced belts between which the spacing is provided to allow a pillow to travel between the belts. To each side of the conveyor belt, a beater is provided. The beaters are rotatably mounted on the frame about shafts defining their axes of rotation. The two beaters rotate in opposite directions and include peripheries defined by two opposed elongated bars substantially parallel to the axis of rotation of the beater. A pillow is fed between the conveyor belts and as it traverses the location where the beater mechanism is located, the beaters sequentially strike the pillow on each side simultaneously to beat the pillow casing and the fiber within, therefore efficiently distributing the fiber fill throughout the pillow casing, removing and lumping, uneven spots, empty areas, and causing the pillow to become more lofty, softer, and completely filled out.

Abstract: Exemplary surface debris removal systems and methods are operable to remove debris from a signal transmitting/receiving surface. An embodiment provides power to, and then removes power from, a conductive memory wire that is secured to a moveable portion of a two-position snap spring. In response to providing the power to the conductive memory wire, a length of the conductive memory wire decreases so that the moveable portion of the two-position snap spring is pulled from an extended position to a retracted position. When power is removed from the conductive memory wire, the moveable portion of the two-position snap spring moves from the retracted position to the extended position. In response to the moving of the moveable portion of the two-position snap spring from the retracted position to the extended position, an energy is generated and transferred to the surface that dislodges the debris from the surface.

Abstract: A dual striker mechanism for a carpet-tapping machine comprises two striker grills which are mounted in a common body opposite one another so as to be pivotable about the longitudinal axis of their retaining rail. The tapping rods of the first striker grill thereby protrude into the gaps between the tapping rods of the second striker grill. The arrangement of the tapping rods of the two striker grills thereby forms a common horizontal plane. The striker grills are coupled to one another such that upon a clockwise pivoting motion of the first striker grill, the opposite one moves counter-clockwise. The drive motor for the striker grills generates an alternating pivoting motion about the longitudinal axis of the striker grills via an eccentric drive. The tapping rods of the two striker grills thereby move toward each other in their common substantially horizontal position.

Abstract: A welding nozzle cleaning device includes a rotary hub and a plurality of flexible arms that extend outwardly from the hub. Each arm is formed of flexible resilient material and has an impact head at its distal end, the head being carried by the hub-and-arm assembly through a circular path of travel.

The beach cleaner 50 includes a frame; keel members, a scraper, and a tow portion that are disposed in a front portion of the frame; a mesh member disposed in a rear portion of the frame. The keel members and the scraper churn up litter scattered on sand ground, along with sand, while the beach cleaner travels on a surface of the sand ground by being towed by a towing vehicle. The churned up litter is deposited in the mesh member. Mesh of the mesh member is relatively rough at a front portion thereof in the traveling direction and finer at a rear portion thereof.

Abstract: Deicing of an external mirror (10) on a vehicle is effected by applying a sudden deformation force to the mirror. Sandwiched between the mirror (10) and a mounting surface (12) is a structure that includes a ribbon conductor (14), portions of which overlap each other in such a way that current through the conductor passes through these portions in opposite directions. A capacitor (32) is discharged through the conductor (14), generating a magnetic field that results in mutual repulsion between the overlapping portions. The mounting surface resists this repulsion force, which is instead transferred to the mirror (10), causing momentary distortion, and dislodgment of ice on the mirror surface. The same technique is also applicable to deicing of windows.

Abstract: The invention relates to an apparatus for brushing chalk powder off from an eraser surface of a blackboard eraser in which elastic brushes attached to rotatable shafts of rotatable bodies are brushingly engaged with the eraser surface and are rotated in forward and reverse directions by a motor so that the chalk powder removed from the eraser is collected in chalk powder receiving containers. After the passage of a set time interval, the operation of the apparatus is automatically stopped. A chalk powder containing eraser and the now clean eraser inside the apparatus can be exchanged. Thus, dispersion of powder into the room is prevented.

Abstract: A method and apparatus for cleaning debris, such as lint-like residue, from the bristle blocks of an automatic fabric cutting machine cutting bed, utilizing a linear motion device connected to a head by motion-amplifying linkages in order to amplify the acceleration produced by the motion device and thereby accelerate a slat of bristle blocks toward a grate. When the slat contacts the grate it is abruptly decelerated, which causes the debris to travel out from between the bristles. The grate is indexed between cycles of the head so that different portions of the slat strike the grate each cycle.

Abstract: The present invention is directed to a stall and pasture vacuum machine which comprises a trailer frame supported by an axle and wheels, a receptacle which is pivoted at one end of the frame and at the other end of the frame is an extension which supports a centrifugal blower and its drive.

Abstract: Disclosed is a ceramic knock-off apparatus for automatically removing the ceramic coating from investment casting molds having a plurality of arms. Prior to operation, a ceramic covered mold is loaded into a receptacle on a turntable and rotated to a starting position thereby placing one of the arms of the ceramic covered mold directly under the head of an air hammer. The apparatus automatically removes the ceramic coating from each arm of an investment casting mold by lowering the air hammer until it engages the first arm of the mold, operating the hammer thereby vibrating that arm of the mold and causing the ceramic coating to break and fall off, raising the hammer, automatically rotating the turntable until the next arm of the mold is aligned under the air hammer, and lowering the hammer to engage the next arm. This cycle is repeated until the ceramic coating has been removed from every arm of the mold.

Abstract: An apparatus for vibrating and dewebbing tire cord fabric treated with a liquid bonding agent for promoting the adhesion between the warp cords of the fabric and the rubbery material in which the cords are embedded. The fabric, freshly coated with the liquid bonding agent, is guided along a desired vertical pathway between a pair of rotating cylindrically shaped cams which are eccentrically mounted for rotation about axes which are equally spaced from the pathway of the fabric. The rotation of the cams is synchronized such that the cams continuously contact the fabric as they alternately push the fabric in opposite directions from the desired pathway to vibrate the fabric between the rotational axes of the cams. Thus, excess liquid coating is shaken from the fabric to help remove any liquid coating webbing the openings between the warp cords and weft threads of the fabric.
