  • Patent number: 5372218
    Abstract: A mini portable scaffolding frame having a structure and design such that it can receive and hold a removable extension member. When two scaffolding frames and its extensions are positioned in a spaced apart relation to receive the placement of wooden planks thereon, a scaffolding system is provided which can be used in small indoor areas which normally could not receive standard scaffolding structures. Each of the frame members includes a pair of rectangular sections pivotally mounted to each other. A base member is fixed to each of the rectangular sections for receiving and holding a detachable extension member.

  • Patent number: 5160435
    Abstract: A method and system for optimizing the operation of a trickling filter. Optimization is obtained by using a controlling device and a variable speed drive in combination. The drive motor rotates the distributor mechanism of the trickling filter in response to signals transmitted thereto by the controlling device. The signals received are either based on the influent flow rate or a pre-programmed system representing the above. In response to these signals, the speed of rotation of the distributor is continually varied to provide a SK value most conductive for (1) reducing the BOD and ammonia levels present in the wastewater influent, (2) removing excess bio-mass attached to the media used in the filter and (3) driving the organic food materials deeper into the bio-mass. SK values of between 5 to 100 mm/pass are used for normal operation and a SK of 100 to 1000 mm/pass for flushing during non-peak hours. An intermediate SK value is used to drive the organic feed deeper into the media.

  • Patent number: 5136732
    Abstract: A pressurized flushing apparatus for commodes in which low volumes of pressurized water are used for flushing. The apparatus includes a pressurizeable tank having a closed water outlet. The tank is pressurized by the introduction of pressurized water into the tank until a pressure of between 8 and 25 psi is achieved. Within the tank is a bellows to which a plug is attached to one end for closing the water outlet. A restrictable open channel connects a pressure zone above the water in the tank with an internal chamber located within the bellows. The open channel is consticted by a needle valve which controls the rate at which the pressure within the pressure zone and the internal chamber are equalized. When the pressure within the internal chamber is reduced to ambient pressure, the bellows will collapse and withdraw the plug from the water outlet. When this occurs, the pressurized water within the tank will be forced out of the tank and into the toilet bowl.

  • Patent number: 5096588
    Abstract: A method and system for optimizing the operation of a trickling filter. Optimization is obtained by using a pair of controlling devices, a timer and an electric motor in combination. The electric motor rotates the distributor mechanism of the trickling filter in response to signals transmitted thereto by the first and second controller. The timer activates the first controller during operation to provide a SK value of between 25-500 mm/pass. During non-peak hours, the timer activates the second controller for flushing the biomass used in the trickling filter operation. The flushing is accomplished at SK values of between 200-1000 mm/pass. A method is also disclosed incorporating the above system.

  • Patent number: 4938311
    Abstract: A kit for use with 2.times.4 and 2.times.6 wood pieces to make sawhorses. The legs are constructed for bent metal rods and are secured to brackets or support assemblies that are dimensioned to receive and support the wood piece. A minimal number of nails or screws for securing the wood to the brackets complete the manufacture. In addition, the legs are pivotally secured and may be folded against the wood pieces for storage or transport.

  • Patent number: 4917322
    Abstract: A cart for spools of wire for transport or dispensing in which the main rigid "U"-shaped handle has an integral lockable hinge on one leg that can be unlocked to enable the leg to be swung away and thereby permit the wheels and wire spool to be removed. The wheels also preferably contain angled spokes to minimize entaglement of the wire during paying.

  • Patent number: 4858253
    Abstract: A swimming pool cover apparatus is described whereby the pool cover may be extended and retracted through a power source. The apparatus includes a drive shaft circumscribed by a pair of sleeves. Each of the sleeves may be selectively rotated through a double-dog clutch system connected to the drive shaft. A cover-collecting drum is connected to one of the sleeves. A pair of cord-collecting reels rotatably circumscribe the other sleeve. Controlled rotation of the two cord-collecting reels is achieved through a ratchet and spring-biased pawl system. This system also permits slippage of either of the two cord-collecting reels when the tension on either one of the reels becomes excessive.

  • Patent number: 4858373
    Abstract: A small animal trap formed as a walled enclosure having an opening for rodent entry, a plunger in the enclosure parallel to the bottom, and a spring for urging the plunger toward the bottom. A bottom trigger pedal is inside the enclosure, a pivotally mounted cocking lever extends from the inside upper part of the enclosure outside thereof to terminate outside at or near the bottom of the enclosure. The tripper pedal is pivotally connected to the enclosure by a short lever that extends outward of the trap and is releasibly engagable with the cocking lever. When the plunger is raised the cocking lever engages the under side of the plunger and also the short lever on the trigger pedal. Upsetting the pedal releases the cocking lever and the plunger. The cocking lever has a long arm and a short arm, the long arm being used to latch the trigger. The short arm which is activated by a rodent is located in the lower part of the enclosure.

  • Patent number: 4856756
    Abstract: A valve assembly for draining water from a well pipe to facilitate the flushing of the pipe or to reduce its weight when removing the pipe from the well without separating the components of the pumping system which are all securely connected. The valve assembly is positioned in an axial line just above the down hole pipe. The assembly includes a short pipe section having drainage ports. A tight fitting sleeve circumscribes the pipe section. The sleeve is spring biased continually urging the sleeve in a downward or closed position. A means is provided that is connected to the sleeve and extends upwardly to the surface where it may be accessed to manually open and close the ports.

  • Patent number: 4788988
    Abstract: A smoking device is disclosed whereby smoke and other gases of combustion can be diluted with air to a pre-selected mixture before being inhaled by a smoker. This is achieved by the use of a carbureting tube which can introduce a metered amount of air into a smoke chamber and thereby dilute the smoke to any desired concentration. The smoke is drawn into the smoke dilution chamber by a piston moving towards the outlet end of the chamber, and then pumped out of the smoke dilution chamber by reversing the motion of the piston. A water chamber may also be included to permit the smoke and other gases to be cooled prior to entering the smoke dilution chamber.
