  • Patent number: 6789574
    Abstract: A pneumatic control assembly includes a valve forming a bore that is openably blocked by a spring-biased, first plug. An inner rod is movable in the bore with a lower end engageable with the first blockage plug and an upper end forming a second plug. The inner rod is spring biased to separate from the first plug. An intermediate rod forms a channel having an opening confronting and separated from the second plug by a basing spring. A vent hole is defined in the intermediate rod and in fluid communication with the channel. A piston is formed around the intermediate rod between the opening and vent hole. An outer rod is supported on the piston by a resilient member. When the outer rod is forced toward the intermediate rod, the resilient member is deformed, driving the intermediate rod toward the inner rod and the second plug blocks the opening of the intermediate rod. The engagement between the intermediate and inner rods drives the inner rod to urge the first plug to open the bore.

  • Patent number: 6736436
    Abstract: A refuse collection device includes a tubular portion to which a bag mount is attached. The bag mount defines a passage. A cover is movably mounted to the bag mount for openably closing the passage. A flexible bag, such as a plastic bag, has a front opening fit over and releasably secured to the bag mount for receiving refuses through the passage. The bag is comprised of first and second sheets, each having a front edge folded over sections of the bag mount. The front edge of the first sheet forms a cut line dividing the front edge into two opposite free flaps for facilitating mounting the bag to the bag mount. A flap retainer is mounted to the tubular portion and is biased by a torsional spring to securely fix the flaps to the bag mount thereby preventing the flaps from arbitrarily moving within the passage and thus enhancing collection of refuses into the bag.
