A first attachment feature extends outwardly in a first direction from the sleeve at the first open end and a second attachment feature extends outwardly in a second direction that is opposite the first direction at the second open end. In a first position, the passage has a first axial length, the first open end lies in a first plane, and the second open end lies in a second plane. In a second position, the passage has a second axial length that is greater than the first axial length, the first open end lies in the first plane or a first new plane that is parallel to the first plane, and the second open end lies in the second plane or a second new plane that is parallel to the second plane.

on Flexible, multi-piece, multi-configuration concrete form system By www.freepatentsonline.com Published On :: Tue, 30 Dec 2014 08:00:00 EST The present invention is directed to a flexible concrete form system having both flexible and rigid parts that are easily assembled and disassembled using a multi-contact point connection system. The concrete form system can be extended or stacked in a wide variety of configurations to accommodate almost any desired concrete shape. Full Article
on Unitary form for poured foundation pad and method By www.freepatentsonline.com Published On :: Tue, 30 Dec 2014 08:00:00 EST A unitary assembly facilitates constructing concrete foundation pads made of poured concrete, the foundation pads being useful to support a structure or building. The apparatus comprises a unitary assembly of existing planar forms connected by taper-shaped corners using wedge connectors to define an upwardly-tapered cavity shaped to hold poured concrete until the concrete cures. The assembly is sufficiently rigid and the planar forms are held at an angle sufficient for the unitary assembly to self-release from the cured concrete without disassembly when lifted/moved vertically off of the cured concrete.

on Molding tool for original shaping or reshaping of components composed of materials that can be thermally influenced By www.freepatentsonline.com Published On :: Tue, 13 Jan 2015 08:00:00 EST The invention relates to a molding tool for the production of components composed of fiber composite materials, in which the molding tool has a fiber composite structure and an electrical resistance heating element, whereby carbon fibers or carbon filaments are embedded into the fiber composite structure of the molding tool in a plastic matrix, close to the shaping surface of the molding tool. Such a molding tool is further developed in that the carbon fibers or carbon filaments in the plastic matrix, close to the shaping surface, essentially determine the mechanical strength of the molding tool, and that the electrical resistance heating element is interconnected in such a manner that at least individual sections of the electrical resistance heating element form an electrical parallel circuit with one another.

on Replication of patterned thin-film structures for use in plasmonics and metamaterials By www.freepatentsonline.com Published On :: Tue, 03 Feb 2015 08:00:00 EST The present invention provides templating methods for replicating patterned metal films from a template substrate such as for use in plasmonic devices and metamaterials. Advantageously, the template substrate is reusable and can provide plural copies of the structure of the template substrate. Because high-quality substrates that are inherently smooth and flat are available, patterned metal films in accordance with the present invention can advantageously provide surfaces that replicate the surface characteristics of the template substrate both in the patterned regions and in the unpatterned regions.
