Patent number: 8863454Abstract: A building curtain wall is formed by vertical frame members carrying panels of glass bridging the space between the members so that edges of the panels are mounted on the members. Each frame member is a hollow pultruded member defined by a thermo-set resin reinforced by reinforcing fibers including longitudinal rovings and a mat located at an exposed surface of the inner wall and the side walls of the generally rectangular member. The exterior surface is defined by the resin which is pigmented but uncoated. In order to provide a required finish to the exterior surfaces the inner wall and the side walls have a thickness of at least 0.090 inch with a difference in thickness therebetween which is less than 20%.Type: GrantFiled: November 14, 2008Date of Patent: October 21, 2014Assignee: Omniglass SCT Inc.Inventors: Laurence W.

Patent number: 7937904Abstract: A corner joint between two frame lineals of a pultruded window frame is defined by inserting a leg of a corner member into a hollow interior of each lineal and attaching the legs to the lineals by adhesive. Each leg has a plurality of surfaces thereof each having a first portion at the corner which lies closely adjacent a corresponding surface of the first lineal and a second portion, at the end of the first portion remote from the corner which tapers inwardly away from the corresponding surface of the first lineal such that a spacing therebetween increases in the direction away from the corner. The adhesive is applied to the tapered portion and the taper acts to force the adhesive along the leg to the first portion and to the ends of the lineals where the excess can be wiped away.Type: GrantFiled: November 10, 2006Date of Patent: May 10, 2011Inventor: Laurence W. Davies

Patent number: 7514135Abstract: A method for forming a pultruded part includes collating reinforcing fibers by providing a first layer of reinforcing rovings extending in the longitudinal pultrusion direction, applying onto the first layer an intermediate layer of reinforcing fibers at least some of which include at least portions thereof which extend in the transverse direction and covering the intermediate layer with a second layer of rovings extending in the longitudinal direction. Alternatively the transverse fiber layer is formed on the inside surface of a hollow part. To the collated fibers is applied a urethane resin so as to permeate through the layers and the materials are passed through a die to form a thermo-set cross-linked poly-urethane. The transverse layer or layers are relatively thin having a weight less than or equal to 0.5 ounces per square foot and more preferably as low as 0.25 ounces or 0.1 ounces.Type: GrantFiled: January 29, 2004Date of Patent: April 7, 2009Assignee: Omniglass Ltd.Inventors: Laurence W.

Publication number: 20080110094Abstract: A mullion for a window frame is formed by two frame members back to back to form the mullion. The facing surfaces are connected by providing aligned first and second recesses therein where each of the recesses has a mouth at the which is narrower than a base and has a connecting member along the aligned recesses with a portion of the connecting member within each recess as a loose fit. Each connecting member has associated with it an insert member with an insert portion between the outer surfaces of the first and second frame members forcing the outer surfaces apart to tighten the connecting member and a cover portion covering a junction between the side surfaces.Type: ApplicationFiled: November 10, 2006Publication date: May 15, 2008Inventor: Laurence W.

Patent number: 6623375Abstract: A golf club iron has a club head having a generally planar generally rectangular front face for impacting a ball with a horizontal top edge and a horizontal bottom edge. The front face is symmetrical about an imaginary upright center line at right angles to a transverse line and equidistant between the sides so that the upright center line and the transverse center line intersect at an imaginary center point of the front face. The club head defines an imaginary horizontal center line at right angles to the transverse line passing through the imaginary center point of the front face and substantially through the center of gravity of the head. A tubular shaft hosel is integrally attached to the rear face of the club head with an axis of the tubular hosel at the club head coaxial with the axis of the shaft. The hosel is arranged so that the axis of the shaft and the hosel intersects the imaginary horizontal center line at a position reward of the center of gravity.Type: GrantFiled: July 23, 2002Date of Patent: September 23, 2003Inventor: Laurence W.
