Patent number: 8455795Abstract: A surface heating system and method of heating a surface in which there are two or more heating cables adapted to be embedded in a cementitious material and using a single feed cold lead wire is described. One or more heating cables are provided to define one or more heating circuits. The heating cables have electrically conductive wires. A cold lead connector is secured to the electrically conductive wires at an end of the one or more heating cables. A feed cold lead wire is secured at one end to a thermostat to which is connectable an electrical supply source, and at a second end to the cold lead connector of the one or more heating cables.Type: GrantFiled: May 15, 2008Date of Patent: June 4, 2013Assignee: Flextherm Inc.Inventor: Philippe Charron

Patent number: 8455800Abstract: The helix heated hoses 10 and 12 use two features to increase the flexibility. The first feature is a braided-copper heating element 14, which has increased flexibility over the prior art solid copper heating element. The element is spiral wound around the hose and held in place with a moisture barrier 16. The second feature is the helix twist 18 located just before the point where the hoses 10 and 12 attach to the manifold 20. The helix feature is created with the helix support 22, which initiates the twist around 24 inches back from the point of termination. The helix feature works to reduce the moment of inertia about the neutral axis 26 of the two supply hoses 10 and 12.Type: GrantFiled: September 11, 2008Date of Patent: June 4, 2013Assignee: Graco Minnesota Inc.Inventors: Joseph E. Tix, Mark T. Weinberger, Douglas S. Ryder

Patent number: 8431867Abstract: A transparent windowpane including a resistive heating coating that extends over a substantial part of a surface of the windowpane, and over a main field of view, and which is electrically connected, at least indirectly, with at least two busbars such that, when a power supply voltage is applied between the two busbars, a current flows between the busbars, heating a heating field in the heating coating. The heating field includes at least one semiresistive region in direct contact with at least one busbar, and including conducting strands in a form of thin longitudinal wires, the ohmic resistance of which is less than that of the heating coating. At least one conducting strand has a transverse conducting structure in electrical contact with the semiresistive region.Type: GrantFiled: January 19, 2007Date of Patent: April 30, 2013Assignee: Saint-Gobain Glass FranceInventors: Ariane Blanchard, Guenther Schall
