  • Patent number: 6270052
    Abstract: A mold is provided for forming a concrete column having at least one recess formed therein, as molded. The mold includes a tubular housing having an inner surface and a recess form having an inner and an outer surface. The recess form is mountable in the housing at a desired location on the inner surface of the mold housing. The recess form is preferably generally a ring The ring's outer surface corresponds to the shape of the housing's inner surface so that, when the ring is mounted in the housing, there are substantially no gaps between the outer surface of the ring and the inner surface of the housing. The ring has a slice through it, so that the ring may be expanded and pried out of the groove or recess molded in the column once the cement has set. Preferably, the slice is off-set from a radial line drawn through the ring. The ring is secured in place in the mold using screws.

  • Patent number: 4738750
    Abstract: A system and method for converting pulp and paper mill waste water into a decolored, neutral pH effluent and a solid suitable for use as fuel in a furnace. The treatment system is used following primary and secondary treatment of pulp and paper mill waste waters typically found in the industry. After secondary biological treatment, the waste waters are pumped to a coagulation tank where the waste water is brought in contact with a polyamine coagulant which coagulates lignins, degraded sugars, and other compounds which typically discolor this water. The coagulation particles are increased in size by addition of an acrylamide polymer in a flocculation tank to improve the hydrophilic characteristics of the coagulant. The waste water is then mixed a dissolved air and water solution under pressure. Upon dissolution of the dissolved air at atmospheric pressure the air is absorbed by the flocculated matter in the aeration tank and the flocculated matter is caused to migrate towards the area of less pressure, i.e.
