Publication number: 20080290085Abstract: A heating cartridge is intended especially for a thermostatic working valve. The cartridge is provided with a resistance wire winding (3), which is wound on a winding support (2) and is embedded in an insulating material filling (5) in a metal sheathing (7). The metal sheathing (7) is provided at one end (6) with a dimensionally stable coupling element (8) manufactured from a plastic, in which connecting lines (17, 18) are arranged, which electrically connect pluggable contact elements, especially pins (9, 10) of a connector plug, to the ends of the resistance wire winding (3). To simplify the manufacture and to obtain a compact design, the connecting lines (17, 18) are rigidly seated in the coupling element (8).Type: ApplicationFiled: May 21, 2008Publication date: November 27, 2008Inventor: Andreas SCHLIPF

Patent number: 7453052Abstract: An electrical distribution apparatus configured to connect a load to a power source is disclosed. The apparatus includes a housing having an air inlet and an air outlet, a distribution conduction path, a thermal sensor in thermal communication with the conduction path, an electrical disconnect, and an airflow generator. The electrical disconnect is connected in series with the conduction path and is configured to isolate the load from the power source on command, the disconnect being in signal communication with the thermal sensor. The airflow generator is in signal communication with the thermal sensor and is arranged to cause air to flow into the air inlet and out of the air outlet. The airflow generator is configured to turn on in response to the thermal sensor sensing a first temperature, and the disconnect is configured to disconnect the load from the power source in response to the thermal sensor sensing a second temperature greater than the first temperature.Type: GrantFiled: November 21, 2005Date of Patent: November 18, 2008Assignee: General Electric CompanyInventor: Stephen G. Midgley

Patent number: 7449661Abstract: A heat trace system (10) is used for heating water to prevent freezing in a conduit (20) while servicing an aircraft positioned at a passenger loading bridge (52). An upstream fitting (26) is attached onto the conduit adjacent to a building structure and a downstream fitting (48) is attached onto the conduit adjacent to the cab of the passenger loading bridge. A coated retractable coiled wire disposed within the conduit and cold lead wires (46) enter through the upstream fitting and leave through the downstream fitting. A low voltage solid state power control box (56) is in communication with the cold lead attached to the coiled wire inside providing regulated electrical energy for heating the coiled wire thus preventing freezing the water within in the conduit.Type: GrantFiled: November 3, 2006Date of Patent: November 11, 2008Inventor: Steven D. Bench

Patent number: RE41715Abstract: A glazing provided with an electric circuit includes an electrically conducting substrate and a terminal for making electrical connection thereto. The terminal is attached to the glazing by an adhesive, rather than solely by solder, and the electrical connection between the terminal and the substrate is provided by means other than, or additional to, physical contact between the terminal and the substrate. For instance, the adhesive may be electrically conducting, or a soldered joint may additionally be provided if the adhesive is electrically insulating, or of insufficient conductivity for the type of circuit in question. The adhesive may be pre-applied to the terminal, and may be a tack-free adhesive activated or cured by heat. The terminal may be in two parts, with the base part of a standardized design. The glazing is suitable for use in buildings, appliances or vehicles, especially automotive vehicles.Type: GrantFiled: January 25, 2001Date of Patent: September 21, 2010Assignee: Pilkington Italia S.p.A.Inventors: Luigi Capriotti, Ciro Paudice
