Abstract: A heating system for a motor vehicle having an electrical supply circuit and an engine liquid cooling assembly includes a housing structure having an inlet duct, an air outlet duct and means such as a fan for creating a flow of air into the inlet and out of the outlet. The electric heater is capable of being heated to 1,800° F. in three (3) seconds or less disposed in said air flow to heat the air passing therethrough. The system further includes means for heating the flow of air by exposure to heated coolant and means for deactivating said electric heater when the air flow is being heated by the heated coolant.

Abstract: The invention relates to a method for producing a ceramic-metal connection that is repeatedly subjected to great changes in temperature during use, in which the metal and ceramic are brazed to one another two-dimensionally.

Abstract: A gas igniter includes a heating element, a bushing and a mounting bracket. The bushing is formed of a generally rigid electrically insulating material and supports the heating element. The bushing includes an elongated slot extending through the bushing. The mounting bracket includes a first connecting portion and a second mounting portion. The first connecting portion is inserted through the elongated slot located on the bushing for connecting the mounting bracket to the bushing. The second mounting portion is configured to attach the gas igniter to an associated support surface.

Abstract: A multi-layer rod shaped ceramic igniter includes an elongated tapered electrode having a central core of resistant material and two annular segments. One of the segments in on one side of the core and the other on an opposite side and connected to two slightly converging facets extending along the core. The multi-layered rod shaped ceramic igniters disclosed herein may be manufactured by slip-casting, injection molding or extruding a green annular body and removing material from opposite sides of the green body to form two almost parallel but slightly converging facets that extend over the heater igniter between the back surface and the tip of the igniter. After removing material between the annular segments the igniter is air dried and then heated in a vacuum at atmospheric pressure to approximately 900° C. in order to burn off the organic binder. The ceramic is then held in an inert atmosphere and heated to a temperature of 1600° C.

Abstract: The present invention relates to a novel electrical devices fabricated from polycrystalline silicon carbide (SiC) and methods for forming the same. The present invention provides a method for fabricating polycrystalline silicon carbide (SiC) products infiltrated with SiC-containing preceramic precursor resins to substantially mask the deleterious effects of trace contaminants, typically nitrogen and aluminum, while reducing operative porosity and enhancing manufacturing ease.

Abstract: A gas igniter comprising an heating element and a mounting bushing. The heating element includes an elongated high resistance cylindrical nose coil and two rear terminal elements electrically insulated from each other, and an input lead connected to each of the elements. The bushing is formed from a generally rigid electrically insulating material for mounting the heating element onto an external support structure. A passage in the bushing receives the heating element with a gap between the heating element and the passage, an adhesive mass in the gap secures the heating element into the bushing and a sheet metal mounting bracket is integrally formed with the insulating material of the bushing.
