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: An electrical energy storage device for storing electrical energy and supplying the electrical energy to a driving motor at different power levels is disclosed. The electrical storage device has an energy battery connected to a power battery. The energy battery has a higher energy density than the power battery. However, the power battery can provide electrical power to the electrical motor at different power rates, thereby ensuring that the motor has sufficient power and current when needed. The power battery can be recharged by the energy storage battery. In this way, the power battery temporarily stores electrical energy received from the energy battery and both batteries can provide electrical energy at the different power rates as required by the motor. The energy storage device can be releasably connected to an external power source in order to recharge both batteries. Both batteries can be recharged independently to optimize the recharging and lifetime characteristics of the batteries.

Abstract: Electrical contact outlet for an anode sheet of a lithium generator with polymer electrolyte, consisting of one or more multilayer electrochemical cells. The cell comprises at least one lithium base sheet having a thickness between about 1 and 50 microns to constitute the anode and its collector and additionally includes a cathode and its collector as well as the polymer electrolyte. A lateral end of the anode sheet extends beyond corresponding ends of the cathode and the collector to constitute a projecting zone. A metallic layer consisting of at least one rigid metal which is compatible with lithium is in electrical contact with the lateral end of the anode sheet but without electronic contact with the other components of the cell. The metallic layer constitutes the external terminal of the generator when the latter is in non-finished condition. According to a variant, a conductive and cohesive intermediate metallic zone, which consists of lithium or lithium rich ductile alloys is in intimate contact with the lateral end of the anode sheet and the metallic layer mentioned above is therefore in electrical contact with the lateral end of the anode sheet by means of the intermediate zone of lithium. Generators provided with such contact outlet as well as a process for the preparation of these contact outlets are described.
