Patent number: 7147741Abstract: The fundamental technique of the method for making cellular cores is to make stacks of components which are configured such that cutting slices off the stacks produces cellular cores and, when needed, components used in stacks used to produce cellular cores. One of the basic components used in the stacks is termed a ribbed ply which is a ply (thin sheet of material such as wood) with a number of ribs (long thin strips of material such as wood) attached to the ply, parallel to each other. The spaces between the ribs are filled with filler material such as foam plastic, and the cells in the cellular core are filled with the filler material. The filler material is introduced as layers of the material stacked alternately with plies and adhesively attached. Slices of such a stack, sliced parallel to the grain of the plies (if wood) are called ribbed fillers. Stacking ribbed fillers and plies produces a stack having a cross section which, when sliced, produces filled cell cellular cores.Type: GrantFiled: February 15, 2005Date of Patent: December 12, 2006Inventor: Peter Sing

Patent number: 7010897Abstract: A construction element 1 consists of multiple individual layers 2, 3, 4 whereas the medium layer 3 is in turn composed of a multitude of additional individual layers 23, 24, 25. The individual layers 2, 4, 23, 24, 25 are configured in such a way that they interlock and clamp into each other thereby producing or defining surfaces that allow the elements or individual layers 2, 4, 23, 24, 25 that are integrated in the construction of the construction element to evenly absorb the forces that are being applied. At the same time, not only pressure or lateral forces but also tensile and transverse forces can be absorbed so that altogether a construction element 1 with a low weight but high stability has been created. This construction element 1 can be shaped or deformed appropriately and can also be extended three-dimensionally so that an adaptation to the individual conditions in any plane or direction is possible.Type: GrantFiled: May 25, 2000Date of Patent: March 14, 2006Inventor: Peter Kuppers

Publication number: 20020108349Abstract: An aluminum fire-resistant honeycomb-shaped plate and its manufacturing method includes an aluminum intermediate honeycomb-shaped layer, a layer of gauze adhered respectively on an upper and a lower surface of the intermediate honeycomb-shaped layer, an outer solid aluminum plate adhered respectively on an outer surface of each layer of gauze. The gauze endures high temperature and percolates air. Then the outer surface of each outer solid aluminum plate is anodized with a layer of a chemical to prevent it from getting rusted and then sprayed with a layer of silicon glue to increase hardness of the outer surfaces and beautiful appearance.Type: ApplicationFiled: February 15, 2001Publication date: August 15, 2002Inventor: Chin-Chung Liu

Patent number: 6401413Abstract: An insulated concrete form wall building system wherein a first embodiment includes a pair of spaced apart elongated expanded polystyrene sidewalls, each having opposed inner surfaces that are formed with longitudinally spaced apart vertically oriented ribs that terminate in substantially flat surfaces to abut against one another to serve as a concrete wall form. A second embodiment includes a pair of spaced apart elongated expanded polystyrene sidewalls and divisional members with flat sides which are attached to said sidewalls to serve as a concrete wall form. The ribs define channels for receiving concrete poured therein to form a composite polystyrene and concrete wall structure in the first embodiment and the divisional members serve the same function in the second embodiment.Type: GrantFiled: June 30, 2000Date of Patent: June 11, 2002Inventor: Michael H. Niemann

Patent number: 6393776Abstract: A protective shelter for installation above and in the ground including a superstructure style frame, a composite wall structure for absorbing energy from missile impacts, and a tub encased in a foundation. The invention also discloses a method for constructing a protective shelter including a tub form and a superstructure which includes utilizing the availability of the tub form to provide a downward force such that the superstructure is not floated out of the excavation when the encasement is poured and removing the downward force after the concrete encasement has reached initial set stage. A further disclosure of the invention includes an energy absorbing compound wall structure for dissipating, transferring, and converting to potential energy the kinetic energy of a missile impact.Type: GrantFiled: March 24, 2000Date of Patent: May 28, 2002Inventors: James E. Waller, Ian E. McElwain

Publication number: 20020020120Abstract: A modular exhibit panel and lock system includes a firstwedge secured within a first channel of a first object, such as a modular exhibit panel. A second wedge is secured within a second channel of a second object, such as a second panel. The first and second objects are securely associated with one another by placing the first wedge in the first channel, and the second wedge in the second channel in an orientation generally opposite of a first wedge and sliding the first and second channel relative to one another so that the first and second wedges interlock causing the first and second objects to be connected to one another. A multi-faceted panel connector having channels in at least two facets thereof, and a third wedge within these channels, can be used to securely associate panels of the system with one another.Type: ApplicationFiled: August 1, 2001Publication date: February 21, 2002Inventor: Alexander L. McKenzie

Patent number: 6345486Abstract: An expandable and contractible honeycomb insulating panel is described. The panel is formed by attaching a plurality of adjacent embedded tubular cell units, wherein each embedded tubular cell unit comprises at least one side having multiple layers of material. In this manner, the panel has superior insulating or light blocking capabilities in a volume comparable to a honeycomb panel made of tubular cells having a single layer of material. In another form, a retractable cover for an architectural opening is described that includes such a honeycomb insulating panel. Also, the honeycomb insulating panel may be enclosed to provide insulation.Type: GrantFiled: April 19, 2000Date of Patent: February 12, 2002Assignee: Hunter Douglas Inc.Inventors: Wendell B. Colson, Paul G. Swiszcz, Jason T. Throne

Patent number: 6286289Abstract: An isogrid structure formed from multiple face sheets (14) and multiple stringers (16). Each face sheet (14) and each stringer (16) being an individual component. Each stringer (16) having two or more joints for attachment to the face sheets (14). The face sheets (14) formed from flat sheet material and include a pattern of openings for attachment of the joints on the stringers (16). The geometry of the openings matching the geometry of the joints on the stringers (16). The assembled unit is formed by inserting each joint on a stringer (16) through its corresponding opening in a face sheet (14) and then bonding the joint to the face sheet (14).Type: GrantFiled: December 8, 1999Date of Patent: September 11, 2001Inventors: John W. Powell, Stanley D Hisel, Matthew J Dvornak
