Appl. No.:

09/513144

Inventors:

Lyle J. Clemenson - Brooklyn Park MN

Assignee:

Environmental Filtration, Inc. - Brooklyn Park MN

International Classification:

C02F 700

US Classification:

210747, 210163, 210237, 210170, 21049701

Abstract:

A filter canister for use within a storm water sewer system. The filter canister includes a hollow retention body and a lower tapered filter. The retention body defines a top and a bottom, and is positionable within the storm water sewer system so as to direct fluid flow from the top to the bottom. The lower tapered filter defines a vertex end and a base. The lower tapered filter is attached to the bottom of the retention body such that the vertex end extends upwardly toward the top. In one preferred embodiment, a pelletized treatment media, such as peat-based, activated carbon-like pellets, is contained within the retention body. During use, the treatment media removes contaminants from water flow entering the filter canister. The lower tapered filter directs the removed contaminants toward an outer periphery such that the accumulated contaminants have minimal effect on a flow rate capacity of the filter canister.

International Classification:

B01J 2022

US Classification:

502404

Abstract:

A method of processing peat for use in treating a contaminated aqueous solution, especially storm water runoff entering a sewer system. The method includes mixing raw peat with heated sulfuric acid to produce a slurry. The slurry is dried and then mixed with a binder medium to produce an aggregate material. The aggregate material is extruded to form a plurality of pellets. The plurality of pellets are then baked in an oven preferably providing a low oxygen environment at a temperature in the range of approximately 900-1100 degree F. Peat processed in accordance with the present invention serves as both an ion exchange material as well as an organic retention material.

US Classification:

144176000, 144230000, 407034000

Abstract:

A universal pocket and method for attaching a tooth to a cutter wheel of a tree stump removal machine is described. The pocket includes a pocket body defining opposing wheel and exterior faces, opposing planar leading and trailing edges, a tooth receiving slot, a counter sunk bore, and a threaded bore. The tooth receiving slot is linearly formed in the wheel face and extends between the planar leading edge and the planar trailing edge. The counter sunk bore extends between the exterior face and the wheel face and has an enlarged diameter adjacent to the exterior face. The threaded bore extends between the exterior face and the wheel face. In particular, the bores are located on either side of the tooth receiving slot and equidistant between the planar leading and trailing edges. In this regard, the pocket is symmetric with respect to a line bisecting the bores.

Abstract:

A tool assembly for attachment to a cutter wheel for use in tree stump removal is described. The assembly includes a tooth and a pocket. The tooth includes a cutting head and a shank depending from the head. The shank includes a first flat opposite a second flat. The pocket defines opposing wheel and exterior faces. A tooth receiving slot is formed in the wheel face and includes a base. In this regard, the tooth shank defines one of a projection and a recess and the pocket defines the other of the projection and the recess. Upon coupling the tooth shank to the tooth receiving slot, substantially an entirety of a peripheral edge of the projection contacts a wall of the recess to resist a torque applied to the cutting head.

International Classification:

E21C025/10

US Classification:

299106000

Abstract:

The present invention relates to impact-type cutting tools used to pulverize and displace road construction materials, aggregate, earth strata, or the like. In particular, the present invention relates to a rotatable tool bit and assembly for use in such impact-type cutting tools, wherein tool bit life is improved and tool bit change-out time is reduced.

US Classification:

144235

Abstract:

A stump cutting tooth structure which includes a rotatable disc having a plurality of teeth in holding members spaced about the periphery there of, each holding member being formed of mating halves mounted upon opposite sides of the disc, the mating halves having open slots in their facing sides, the slots being parallel to the adjacent surface of the disc, the teeth having shank portions disposed in the slots and having head portions extending outwardly there of radially of the disc and being angled to diverge from one another and to be twisted axially of their shank portions outwardly of one another to have their cutting face portions each at an obtuse angle to their respective cutting directions whereby their cutting face portions slice into a stump in their cutting action instead of flatly inpacting the stump.
