  • Patent number: 6193178
    Abstract: A waste disposal apparatus is disclosed. The apparatus comprises a crushing device for crushing the waste; a ripping device for ripping the waste; a sieving device having an upper mesh and a lower mesh for sieving out the larger waste blocks and the smaller waste blocks respectively by means of vibrating; an initial separation device for sieving out the smaller waste blocks separated from the lower mesh by employing a number of gates and utilizing the fact that different kinds of waste are different in specific gravity and thus having different immersion depth in the water; a cutting device for cutting the waste blocks with lower specific gravity; an advanced separation device for further sieving out the cut waste pieces; and a strainer device for sieving out the fined waste. By utilizing this apparatus, the purposes of saving power, reducing operation and maintenance costs, and lowering the failure times in a waste disposal process are realized.

  • Patent number: 5819318
    Abstract: A head covering is provided with an adjustable sunshade visor for shielding the wearer's face from sunshine and an inside ventilation means for supplying air to the inside of the head covering to cool the wearer's head in hot days. The head covering includes a frame; a substantially C-shaped rim made of flexible material mounted on the bottom of the frame. A size adjusting belt is joined to the C-shaped rim in such a manner as to form a ring that fits on a wearer's head, the diameter of the ring being adjustable by adjusting the length of the size adjusting belt. A plurality of tubular members having hollowed inside are mounted along and between the outer and inner walls of the C-shaped rim. A double-layer crown-structure including an outer fabric layer and an internal net-like layer is supported on the frame for covering the wearer's head. The outer fabric layer and the internal net-like layer are separated by a gap that serves as an air passage.

  • Patent number: 5408760
    Abstract: A shoe is provided with an air pumping device capable of supplying fresh air from the ambient atmosphere into the interior of the shoe. The air pumping device is detachable from the shoe so that it can be cleaned to remove dirts or alien objects that may block the air flow path. The air pumping device is located beneath the forepart of a foot wearing the shoe. When the user makes a step forward, an air bag is compressed at the instant the forepart of the foot is bent to lift the heel off the ground, thereby generating an air pumping action. When the forepart of the foot stretches straight again, the air bag restores to its original shape, thereby generating an air sucking action. As the user keeps moving, the air pumping device will pump air successively from the ambient atmosphere into the interior of the shoe. The air flow direction may be reversed so as to pump air inside the shoe out to the ambient atmosphere.
