Patent number: 6581300Abstract: A method and apparatus for drying veneer wherein the feeder upstream of the drying station displaces the veneer at different speeds on the right and left sides of the transport path of the veneer as seen in the direction of transport so as automatically to impart an inclined orientation of the veneer of 20° to 60° to a line perpendicular to the transport direction before the veneer reaches the drying station. In the drying station and the cooling station the veneer retains this inclined orientation and in these stations the veneer is subjected to multiple rerouting or the application of pressure.Type: GrantFiled: December 20, 2001Date of Patent: June 24, 2003Assignee: Babcock-BSH GmbHInventors: Ingo Grebe, Helmut Wünsche

Patent number: 6581302Abstract: In known rack dryers, the drying effect is weaker in the outer area on the side of the air intake into the pipe chambers than in the other areas. Said weaker drying effect is caused by turbulence in this area, which leads to a drop in the static pressure. The aim of the invention is to provide a dryer which ensures even drying of the goods across the entire width, even in the problem areas. The rack dryer is equipped with conductive bodies (20, 26) which are located on the partition wall (5) and which streamline the current in the area of the air intake into the pipe chambers in such a way, that a predominantly even static pressure prevails throughout the entire pipe chamber. The invention can be used for drying sandwich-type plaster board or wood veneer.Type: GrantFiled: August 17, 2001Date of Patent: June 24, 2003Inventors: Rudi Philipp, Burkhard Behrendt

Patent number: 6581334Abstract: A high strength T-joint for inflatable tubular is formed by forming a butt joint between the end of a first two tubular member and the side wall of a second tubular member. The opening in the side wall of the second tubular member is sized to match the end of the transverse support member so that a sealing flange can be applied to the inner surface of the joint to provide an airtight seal. A reinforcing flange comprising a disk-shaped piece of fabric having a center opening, is then bonded over the opening in the second tubular member. The center opening in the reinforcing flange is substantially smaller than the opening in the side rail member. Therefore the reinforcing flange substantially reduces the size of the discontinuity in the side wall of side rail member, thereby substantially increasing the circumferential (“hoop”) load capacity of the side wall of the side rail member and substantially increasing the rupture pressure of the joint.Type: GrantFiled: November 2, 2001Date of Patent: June 24, 2003Assignee: Goodrich CorporationInventors: Ted H.

Patent number: 6581344Abstract: A workstation for a work environment having a floor is disclosed. The workstation includes a plurality of frame sections, and a latch mechanism releasably and rigidly securing at least one frame section to the floor. The latch mechanism includes a latch coupled to one of the frame sections, a wedge coupled to the latch, and a clip disposed between the latch and the wedge. The clip has a pair of flanges with ends capable of being disposed at least partially beneath the floor. The latch is configured to move the wedge between the flanges of the clip to operate the latch mechanism between a latched position and a released position so that the workstation may be quickly and easily disassembled. A workstation for a work environment having a floor having an aperture is also disclosed. The workstation includes among other features a latch mechanism having a sleeve and a wedge that may be inserted into the sleeve so that an end is at least partially disposed within the aperture.Type: GrantFiled: November 28, 2000Date of Patent: June 24, 2003Assignee: Steelcase Development CorporationInventors: Mitchell Niewiadomski, Frederick S.

Patent number: 6581345Abstract: The present invention provides a track concealment system for use with a movable wall system having movable walls, a track and a trolley. The invention includes a pair of panels, each sized to conceal a portion of the track, and a pair of brackets each having a first portion attachable to the track and a second portion configured to support an edge of a corresponding panel. When supported by the second portion, the panels are arranged such that the edge of said panel is adjacent the connecting member thereby concealing the track.Type: GrantFiled: April 3, 2001Date of Patent: June 24, 2003Assignee: Modernfold, Inc.Inventors: Thomas L.

Patent number: 6581346Abstract: Thin metal anchoring plates provide mechanical bonding between flooring materials such as concrete and plywood. Teeth punched from the metal plates and bent at right angles on the topside form anchorage for the concrete slab and metal screws anchor the metal plate to the plywood subfloor. The metal anchoring plates allow a thin layer of concrete to form a composite section with residential floor construction and to stay in compression—a state in which cracking cannot occur in concrete. Thus, two inherent problems associated with concrete—it's heavy weight and propensity for cracking are solved and thus, allow it now to be used for residential seamless flooring that can be colored, stamped, and textured, for years of low maintenance fire resistant use.Type: GrantFiled: March 21, 2001Date of Patent: June 24, 2003Inventor: Robert C. Melland

Patent number: 6581347Abstract: An expansion joint cover (10) comprises a first plate (18) hingedly attached to a first surface (14) of an expansion joint (12), a second plate (20) hingedly attached to the first plate (18), and a housing (26) fixedly secured to a second surface (16) of the expansion joint (12). During installation, a front plate (52) of the housing (26) can rotate about a hinge (58) to allow the second plate (20) to be installed within the housing (26). In use, the second plate (20) slides within the housing (26) to accommodate variations in separation distance and vertical offset between the two surfaces (14,16). Two hinges (36,44) accommodate variations in torsion between the two surfaces (14,16). The combination of the second plate (20) sliding within the housing (26) and the two hinges (36,44) accommodates variations in lateral offset between the two surfaces (14,16).Type: GrantFiled: February 15, 2002Date of Patent: June 24, 2003Assignee: Balco, Inc.Inventors: Ronny L. Knak, Dean V. Balocca, Johnnie D. Hilburn, Jr.

Patent number: 6581348Abstract: A crush resistant seamless roofing system is formed by a layer of adjacent panels having loose joints filled by expanding rising foam adhesive, which is trimmed to remove excess foam adhesive above a top plane of the roofing system. The roofing system thus formed is covered by a fabric layer and a coating.Type: GrantFiled: December 18, 2001Date of Patent: June 24, 2003Inventor: John P. Hunter, Jr.

Patent number: 6581349Abstract: A method and article of manufacture for building waterproof concrete structures. An integral casing comprised of a rigid plastic shell with an armature attached to its face is covered with concrete. The shell is formed either in the shape of a desired structure or in a generic shape to be used to splice together a larger custom structural shape in a mosaic fashion. The shell acts both as a form to support the wet poured concrete and becomes an integral part of the finished structure to provide waterproofing.Type: GrantFiled: June 4, 1998Date of Patent: June 24, 2003Inventor: Bruce L.
