Filed:

Jun 27, 2001

Appl. No.:

09/892270

Inventors:

Michael J. Kistner - Lockport NY
Paul J. Rowe - Fairport NY

Assignee:

Tec-Kon Enterprises, LLC - East Pembroke NY

International Classification:

E03F 514

US Classification:

210170, 210254, 210519, 210521, 2105321, 210538, 2105121, 404 4

Abstract:

An apparatus for separating floating and non-floating particulates from drain water wherein said apparatus includes a first chamber for collecting non-floating particulates, a second chamber for collecting floating particulates, and a third chamber through which treated drain water can be discharged from the apparatus. An inlet pipe for introducing drain water into the first chamber is provided tangential to the first chamber to provide a vortex flow of drain water into said first chamber. An outlet pipe providing flow of drain water from the first chamber to the second chamber has an inlet at the vortex of drain water flow in the first chamber and an outlet that is spaced a predetermined distance from the floor of the chamber.

Abstract:

A method for making insulated pre-formed wall panels for attachment to like insulated pre-formed wall panels for building a wall. The method includes providing a mold for casting a concrete body having a generally planar portion with a plurality of rib portions extending therefrom, nesting at least one insulation strip within a respective spring member, covering the end portions of the respective spring member with a thermally insulating material to limit thermal conductivity from each respective rib portion of the concrete body to each respective spring member, inserting each respective spring member with the at least one nested insulation strip in the mold, and casting the concrete body in the mold with each respective spring member with the at least one insulation strip being unitarily attached to an edge portion of each respective rib portion with the end portion of each respective spring member being anchored in each respective rib portion of the concrete body to make the insulated pre-formed wall panel. The spring member serves as a nailer strip for the insulated pre-formed wall panel.

Assignee:

Kistner Concrete Products, Inc. - E. Pembroke NY

International Classification:

E04C 252
E04B 176

US Classification:

523023

Abstract:

A prefabricated insulated wall panel for installation with like wall panels for easily and inexpensively building a wall. The wall panel is a unitary combination of (1) a member having a planar portion and a plurality of spaced rib portions integral therewith and extending therefrom for receiving insulation therebetween, (2) insulating material attached to edges of the rib portions for reducing thermal conductivity from the rib portions to wallboard attached to the wall panel, and (3) a nailer for attachment of wallboard.

Abstract:

A method of forming a prefabricated insulated wall panel for installation with like wall panels for easily and inexpensively building a wall. The method includes the steps of providing a mold for casting a concrete member having a generally planar portion including an inner surface and an outer surface and a plurality of rib portions extending from the inner surface to an edge, nesting at least one insulation strip within a respective spring member so that the spring member extends about sides of the insulation strip and terminates in end portions which extend inwardly relative to the insulation strip sides, selecting the spring member to be biased against respective walls of a mold portion corresponding to a rib portion of the concrete member when the nested insulation strip is inserted therein, inserting the nested insulation strip in the mold portion, and casting the concrete member in the mold with the insulation strip and the spring member unitarily attached to a rib portion edge of the concrete member with the end portions of the spring member anchored in the concrete member to make a wall panel.
