Abstract: A dual-acting free body automatic dispenser for dispensing laundry additives into automatic washing machines. The dispenser comprises an assemblage of three major elements: a hollow, spherical container provided with an orifice; a resilient valve seated within the orifice and a rigid stempiece extending axially through the valve. The valve is positioned on the stempiece such that when seated a portion of the stempiece protrudes outwardly beyond the exterior of the container. A mass is attached to the interiorly extending end of the stempiece.The consumer operates the dispenser by filling it with laundry additive, manually seating the valve and placing the dispenser in the washing machine's basket. The dispenser is triggered during the first spin cycle. If the dispenser is oriented with the protruding portion of the stempiece in contact with the basket, centrifugal force causes the container to be forced outwardly relative to the stempiece, thereby unseating the valve.

Abstract: A garment intended to be worn closest to the skin during vigorous physical activities in warm environments. The garment comprises a comparatively open warp knit fabric into the base of which are bound vertically extending cords. The warp knit fabric base is a mesh fabric consisting of thermo-settable synthetic fibres and is set to retain its shape, whereby it forces the cords to be displaced in parallel laterally upon movements, the cords being in contact with the skin. On account of its rigidity, the fabric provides an improved pumping effect upon relative movements between the garment and the body, thus improving the ventilation and carrying away of perspiration from the body. The garment has sufficient width to ensure that it is allowed to move unimpededly over the skin surface of the wearer.

Abstract: An apparatus for reeling and unreeling a flexible cover sheet for a swimming pool. The apparatus has two wheel supported carriage frames at opposite ends of an elongated drum and a stabilizer tube. The elongated drum is coaxial with a front pair of wheels and rotates independently of the wheels. A stabilizer tube is coaxial with a rear set of wheels in unison with them. A drive assembly on one of the carriage frames is operatively connected to the drum. It may be manually operated to reel an elongated flexible pool cover onto the drum. As this is done the cover will pull the carriages along a straight path to the point of connection of the cover end. The carriages are moved outwardly from the fixed cover end to play out the cover over the pool. Both the cover and the rear pair of wheels serve to maintain the drum in a perfect transverse orientation relative to the length of the pool cover sheet so the carriage will track straight and the cover will roll evenly onto the drum.
