Patent number: 6550208Abstract: A constructional component for a wall structure capable of resisting high gravity and lateral loads, both uniform and cyclical, is defined by a partially hollow building block having a generally solid rectangular exterior configuration in which one entire end surface of the building block exhibits a positive deep key geometry and the opposing end surface exhibits a negative deep key geometry, complemental to the positive geometry of the opposite end. Deep key interlocks also exist between opposing horizontal block surface. As partition between vertical cavities of the block may define a Z-shape in horizontal cross-section. There is resultingly created a substantially rigid and load-resilient interlock between vertical and horizontal complemental surfaces when joined as components of a wall structure.Type: GrantFiled: August 21, 2001Date of Patent: April 22, 2003Inventor: Lakdas Nanayakkara

Patent number: 6550209Abstract: Disclosure provides a transformable linked structure, a deployable diagonal structure, a plane stowage-type deployable truss and a line stowage-type deployable truss with high rigidity and reliability constituted by the above-described transformable linked structure and the above-described deployable diagonal structure, and also provides a plane/line stowage truss structure extremely approximated to a spherical surface using the two types of deployable trusses. The present disclosure discloses a module linked structure for linking deployable trusses securely and a holding/releasing mechanism for realizing reliable holding and release. Further, the present invention provides a modular deployable antenna with high precision even if it is large-sized which is realized by spreading mesh on the plane/line stowage truss structure.Type: GrantFiled: January 16, 2001Date of Patent: April 22, 2003Assignee: Nippon Telegraph and Telephone CorporationInventors: Akira Meguro, Jin Mitsugi, Kazuhide Ando

Patent number: 6550212Abstract: A protective drainage wrap comprises a first portion and a second portion. The first portion comprises cross-woven or cross-laminate material in the machine direction and in the transverse direction. The material in the machine direction comprises a polyolefin, polyester, nylon or combinations thereof and has a first thickness. The material in the transverse direction comprises a polyolefin, polyester, nylon or combinations thereof and has a second thickness. The second thickness is at least about 2 times greater than the first thickness so as to assist in providing drainage for moisture build-up. The second portion is a coating comprising a polyolefin, polyester, nylon or combinations thereof. The first and second portions are located adjacent to each other. According to one embodiment, the material in the transverse direction is yarn.Type: GrantFiled: February 20, 2001Date of Patent: April 22, 2003Assignee: Pactiv CorporationInventor: John W. Lubker, II

Patent number: 6550213Abstract: A system for forming concrete slabs has been developed for commercial buildings having a steel moment-frame structure. This system utilizes the cold-formed-steel framing members, such as the wall girts shipped with a particular building package, to be first utilized as slab foundation forming elements before being framed into the building. The system defines foundation geometry upon simple assembly of the forming elements, and efficiently provides for placement of anchoring hardware which corresponds exactly to the connections of the structural frames.Type: GrantFiled: April 9, 1997Date of Patent: April 22, 2003Inventor: Michael G.

Patent number: 6550215Abstract: A casting tool for forming precast concrete wall sections. A base is disposed generally in a horizontal plane and has an upper surface. A pair of opposing sidewalls are disposed proximate the upper surface. Each of the sidewalls has a first position in which the sidewall is located substantially in a vertical plane. First and second opposing bulkheads are disposed proximate the upper surface, each having a respective first position in which the bulkhead is located substantially in a vertical plane. The bulkheads are arranged to abut the pair of opposing sidewalls so that the inner surfaces of the sidewalls, the bulkheads, and the upper surface of the base define a form for receiving concrete to make the precast concrete wall section. The first bulkhead is configured for movement so as to vary a first dimension of the form, and thus the dimension of the concrete wall section.Type: GrantFiled: June 28, 2000Date of Patent: April 22, 2003Assignee: PN II, Inc.Inventors: William J. Pulte, Lawrence J. Wrass, Robert P. Broad
