Publication number: 20020189740Abstract: Methods and systems for making a fiberboard product having a desired final thickness dimension by subjecting a fibrous board preform to a successive series of compressive pressures. Preferably, an upstream one of the compressive pressures causes the board preform to exhibit a compressed thickness dimension which is less than the final thickness dimension of the fiberboard product, while a downstream one of the compressive pressures causes the board preform to exhibit a thickness dimension which is substantially the same as the final thickness dimension of the fiberboard product. Between subjecting the board preform to these upstream and downstream compressive pressures, the upstream one of the compressive pressures may be removed sufficiently to cause the compressed thickness dimension to increase to an intermediate thickness dimension which is less than the initial thickness dimension of the board preform, but is greater than the final thickness dimension of the fiberboard product.Type: ApplicationFiled: June 19, 2001Publication date: December 19, 2002Inventors: Neil A. Carter, Gordon H. Hart, David Rhind

Patent number: 6491818Abstract: A suction strainer includes a hollow internal core tube and an external filtering surface built around the internal core tube. A plurality of openings are defined through the side wall of the internal core tube core. In some cases the openings through the side wall are constructed and arranged such that there is somewhat less open area near the downstream end than the upstream end of the internal core tube, and the amount of open area tapers between the upstream end and the downstream end. As a result, when liquid is drawn into the internal core tube through the plurality of openings, a substantially uniform inflow distribution may be defined along substantially the entire length of the internal core tube. The internal core tube functions as a rigid structural support for the external filtering surface, enabling the apparatus to withstand post-LOCA hydrodynamic forces.Type: GrantFiled: February 9, 2001Date of Patent: December 10, 2002Assignee: Performance Contracting, Inc.Inventors: Paul M. Dwyer, Gordon H. Hart, Carl E. Nuzman, Gordon P. Pinsky

Patent number: 5935439Abstract: An elongated internal core tube suction strainer supported at its ends for use in a suction system is disclosed as is a suction system comprising the elongated suction strainer in combination with ECCS pipes in various support combinations. The elongated internal core tube suction strainer of this invention is particularly suited for use with boiling water reactor (BWR) and pressurized water reactor (PWR) nuclear power plants. Because of the flexibility of the suction strainer of this invention, the suction strainer can be adapted for use in a variety of reactor plants. The elongated suction strainer has an internal core tube defining a plurality of fluid inlets and an exterior filtering structure defining a plurality of perforations.Type: GrantFiled: February 10, 1998Date of Patent: August 10, 1999Assignee: Performance Contracting, Inc.Inventors: Gordon H.

Patent number: 4925622Abstract: An insulation system including support for lagging, especially metal lagging, supports lagging at a distance above industrial piping and prevents fibrous insulation, used to insulate the piping, from being compressed and eventually significantly damaged by foot traffic, thus creating a treadable insulation system with valuable application in nuclear reactor containment areas.Type: GrantFiled: October 27, 1987Date of Patent: May 15, 1990Assignee: Performance Contracting, Inc.Inventors: Latham B. Gray, III, Gordon H. Hart
