Title: Metal oxide varistors having thermal protection
Inventor: ZIEGLER WILLIAM R
IPC: H01C7/12
Filed: 1999-04-30
Abstract: A layer of thermal fusible material is placed on one surface of a metal oxide varistor (MOV) to monitor the heating of the MOV due to applied voltage spikes. The thermal fusible material is part of the electrical circuit which includes the MOV and melts at a predetermined temperature. In the presence of a severe or a number of voltage spikes the MOV heats up and the heat transferred to the thermal fusible material causes it to open the electrical circuit to the MOV to prevent overheating and thermal runaway.

Title: Process and apparatus for the thermal conversion of residues
Inventor: EIDNER DIETER
IPC: B01J19/00
Filed: 1999-05-21
Abstract: In a process for the thermal conversion of combustible energy-containing residues having varying particle sizes at temperatures above the melting point of mineral constituents of the residues to produce solids and off gases by reacting residues with oxygen and/or air at atmospheric pressure, the residues are fed via a feed apparatus into a upper area of a high-temperature reactor together with an air stream or oxygen stream and brought to reaction. The residues are converted to liquid slag and gas in the high-temperature reactor.      The liquid slag is dammed in a melting bath situated in a lower area of the high-temperature reactor. The fine-particle content of the residues is essentially converted to slag and gas in a vertically disposed free space of the high-temperature reactor. The coarse-particle content of the residues is essentially converted to slag and gas in and on the melting bath.      The liquid slag produced flows beneath a damming element and, above an overflow element is removed from the high-temperature reactor together with the gas produced via an outflow hole of the high-temperature reactor.
