  • Patent number: 9166400
    Abstract: An electrical system responsive to overheating and/or electric arcing of an electrically conductive member, e.g. a heating member of an aircraft windshield, includes a first switch in a first current path, and a second switch in a second current path. The first current path is from an electrical power supply through the first switch, through an arc sensor to the heating member to the power supply. The second current path is from a temperature sensor monitoring the temperature of the heating member through the second switch to a temperature controller. When the temperature of the heating member is at or above a predetermined value, the temperature controller causes the first switch to open. When there is arcing, the second switch is moved to the open position. The temperature controller senses that the second switch is open and causes the first switch to open.

    Abstract: A protective handle sheath including a body adapted to wrap about the existing appliance handle, a heat-activated anti-bacterial agent impregnated within the body, and first and second hook and loop strips attached to oppositely situated first and second longitudinal edges of the body respectively. The first and second hook and loop strips generate heat when engaged with each other such that the heat is transferred through the body and thereby transforms the anti-bacterial agent from an inactive state to an active state. In this manner, the anti-bacterial agent is released out from an interior of the body and thereby adapted to directly contact an outer surface of the existing appliance handle. Conversely, the anti-bacterial agent automatically returns to an inactive state when the first hook and loop strip is separated from the second hook and loop strip. Thus, the inactive anti-bacterial agent is absorbed into the interior of the body.

The method includes the step of arranging the first and second tubular members in overlapping relation with an end of the first tubular member inserted into an end of the second tubular member and with the welding ring encircling the first tubular member and compressed between the first and second tubular members. The method also includes the step of applying electric energy to the resistance coil to melt the at least one layer of plastic so that, upon cooling, the respective ends of the first and second tubular members are welded to the welding ring.

  • Patent number: 6002117
    Abstract: A heating cord utilizes a non-heating core conductor that is wrapped with a high temperature insulator. The high temperature insulator is wrapped with a heat resistant insulator, wherein the heat resistant insulator is spirally wound with a heat generating wire. Finally, an insulation sheath covers entire embodiment forming a heat-generating cord. The core conductor and the heat generating wire are connected, forming a single electronic circuit wherein the electric current flowing along the core conductor flows in the opposite direction of the electric current flowing along the heat generating wire. As a result, the opposing electromagnetic fields generated by the opposing flows of electric current neutralize each other and function to reduce electromagnetic field emissions generally known to be harmful to humans. The present design allows safe operation well above the approximate 100 watt limitation inherent in designs that utilize resistive, heating-generating core elements.

  • Patent number: RE41715
    Abstract: 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.
