Publication number: 20070045287Abstract: An improved PTC device and method of manufacturing is disclosed. In one embodiment, the device and method incorporates an improved metal-ceramic composite PTC material manufactured by: (a) heating a ceramic material to a sufficiently high temperature to induce the ceramic material's PTC properties; (b) grinding the ceramic PTC material into a powder; (c) mixing the ceramic PTC material powder with a metal material powder so as to produce a metal-ceramic composite material powder; and (d) sintering the composite material powder at a temperature between 600° and 950° C. In alternative embodiments, an improved multi-layer structure and method of manufacturing such a structure is disclosed. In various embodiments, a PTC device made in accordance with the improved multi-layer structure and method of manufacture may or may not incorporate the improved metal-ceramic composite PTC material disclosed herein, but may use conventional ceramic-based PTC materials.Type: ApplicationFiled: August 26, 2005Publication date: March 1, 2007Inventors: Xiang-Ming Li, Xiaopeng Yang, Liwu Wang, Daniel Chang

Publication number: 20070045288Abstract: There is disclosed an apparatus having a housing, a heating element, a heating element switch, a heating chamber, a heating chamber cover, and a controller. The housing is handheld. The heating element is disposed within the housing. The heating element switch may be electrically coupled with the heating element. The heating chamber is disposed within the housing. The heating chamber cover may be adapted to at least partially eject the heating chamber from the housing when the heating chamber cover is displaced relative to the housing. The controller is electrically coupled with the heating element switch. The controller is adapted to control a transfer of energy to the heating element. The controller may be adapted to prevent the transfer of energy to the heating element if the heating chamber cover is not in a closed position relative to the housing.Type: ApplicationFiled: December 30, 2005Publication date: March 1, 2007Inventor: Stephen Nelson

Publication number: 20070045289Abstract: A portable cart is provided for spraying viscous coating material. The cart holds a resin container and an activator container, each of which is separately heated by conduction. Material transfer lines run from the containers to a spray gun, and the lines are heated. A gas tank and pressure regulator provide compressed gas to the spray gun for spraying the coating material. The spray gun is a positive displacement gun. A direct current, double stack, low-ramp motor drives two material transfer pumps to force the resin and activator through the lines to the spray gun. The two pumps are each driven through a separate helicoidal gear box. A single 110 volt AC input provides the power for the entire cart.Type: ApplicationFiled: August 1, 2006Publication date: March 1, 2007Inventors: John Kott, Kenneth Kott
