Abstract: An apparatus for sorting textile bobbins into groups of empty bobbins and bobbins with residual yarn thereon, utilizing an inclined upwardly moving conveyor belt covered with card clothing for conveying upwardly and discharging therefrom bobbins having residual yarn thereon by engagement of the yarn by the card clothing and for downward sliding discharge therefrom of empty bobbins, and utilizing another inclined conveyor belt to transport and feed bobbins onto the card conveyor. By utilizing a wall extending between the two conveyor belts and providing an opening therein of a predetermined size and shape at the location at which bobbins are fed onto the card belt such that only empty bobbins or bobbins having less than a predetermined amount of yarn thereon can pass therethrough onto the card belt, bobbins can be additionally sorted according to the amount of yarn thereon.

Abstract: This invention relates to an air-floating saucer toy, comprising a housing, of which the main dynamic elements including saucer, air pump, electric motor, speed-reducing device, pneumatic tube and batteries are carried. The saucer is driven to float along a circular slot in the housing by the pneumatic discharge from the air pump through an injection nozzle at the outer end of the pneumatic tube, which travels in a circular path below the slot, the saucer thereby moving along an orbit corresponding with the slot and in the same direction as the end of the tube.

Abstract: A coating system of high tensile strength and resilience for use as a coating for roofs, swimming pools or the like having an underlayer of coating material, an intermediate layer of woven fiber glass fabric that includes strands of bulked yarn in a relatively loose weave, and an overlayer of coating material, with the fiber glass fabric being embedded in the coating system between the underlayer and overlayer. Alternatively the underlayer may be of asphalt material and the overlayer may be a first overlayer bonded to the underlayer with the intermediate layer embedded therebetween and a second overlayer bonded to the first overlayer. The coating material contains water, a high solids thermoplastic acrylic emulsion, calcium carbonate, titanium dioxide, sodium salt of polymeric carboxylic acid, a wetting, emulsifying and stabilizing agent and defoamers, with zinc oxide being used if desired for mildew resistance.

Abstract: An internal loading cylindrical air filter apparatus having a circular tubular knit pile fabric filter element extending unsupported between end plates to provide an essentially full length unobstructed filter area, and having a rotating internal suction cleaning nozzle therefor. The tubular filter element is supported at its entry end by a detachable angle ring having a cylindrical ring flange extending through an opening in the entry end plate of the apparatus to permit endwise assembly and disassembly of the fabric filter element into the apparatus. Annular or helical strands may extend in circumferential engagement with the filter element for restraining it from ballooning out of effective cleaning distance with respect to the rotating suction nozzle under heavy filtering conditions, and a crank may be provided for adjusting the extending length of a helically extending restraining strand for controlling the degree of restaint imposed on the filter element.

Abstract: An automatic door closer providing for use as a light duty door opener and having a slip clutch for protecting the electric gear drive power unit from damage due to overspeeding on excess loads applied by overriding manual door operation. Zener diodes across the power supply to the electric drive motor effectively throw a heavy electrical load on the motor and cause the clutch to slip if the motor is sufficiently oversped and caused to act as a higher voltage bucking generator, as by manually forcing the door substantially faster in the direction in which it is being driven. A direct current motor is used at considerably lower than its rated voltage so that electrical power may be safely applied continuously for holding the door closed with the motor stalled, and without the clutch slipping, with the clutch set to slip only when the force applied thereto is significantly higher than the force required to stall the motor yet safe for the drive unit.
