Abstract: A battery box sealable against moisture and oxygen ingress and liquid electrolyte egress. The battery box includes a first end, a second end opposite the first end, and sidewalls extending between the first and second ends to define a chamber for housing a number of rechargeable lithium battery cells. The first end and the sidewalls are metallic and have a substantially moisture and oxygen gas impervious joint between them. The second end is of a metal plastic laminate joinable to the sidewalls by a joining medium to form a substantially moisture and oxygen impervious joint therebetween. The second end has electrical connectors extending through it which enable substantially moisture and gas impervious connection to be made between current collectors of the lithium battery cells and the outside of the battery box.

Abstract: An improved ceramic heater to be incorporated in a glow plug is described. The heater is made up of a ceramic core enclosed by two layers sintered together to form a unitary ceramic heater. All three component elements of the heater are composed of silicon nitride containing different concentrations of an electrically conductive ceramic substance, such as titanium nitride, titanium carbonitride or molybdenum disilicide. Each component additionally contains low amounts of sintering additives. The core of the heater has the highest concentration (46-75 vol. %) of the electrically conductive substance. The core enclosed in a ceramic layer which is an electrical insulator and is composed of silicon nitride, less than 28 vol. % of the electrically conductive ceramic substance and sintering additives. An outer layer over the core contains the electrically conductive ceramic substance in a concentration (33-50 vol. %) which is in between that in the core and that in the insulator layer. One end of the core is integrally connected to the outer layer over it. The ceramic heater is fitted into a glow plug housing. The core and the outer layer properly joined to appropriate connectors in the glow plug housing form an electrical circuit when connected to an electrical power source.

Abstract: A ceramic heating rate regulator for electrically powered thermal treatment operations is described. The regulator is made of a ceramic mixture containing molybdenum disilicide, which is an electrically conductive substance undergoing crystal structure transformation above 700.degree. C. The regulator comprises an elongated ceramic rod containing high concentration of molybdenum disilicide, the rod is subsequently insulated by a ceramic cylinder which contains silicon nitride and low concentrations of molybdenum disilicide. The regulator when incorporated in the heating circuit of the thermal treatment furnace will itself heat up and thus reduce the size of the heating current flowing in the circuit, as soon as the temperature of the regulator has reached the transformation temperature of molybdenum disilicide. The heating rate regulator is designed to be used in conjunction with conventional temperature controlling devices.
