Title: Multiple filament lamp for traffic lights - has auxiliary secondary filament taking over when main filament burns out
Inventor: MEIER JOACHIM
IPC: H01K9/02
Filed: 1979-06-15
Abstract: The lamp has two (or more) filaments connected to three external connection points such that when one filament burns out the other can be used as a replacement. A device generating a magnetic field is located inside or outside the lamp. The magnetic field is arranged so that it moves any arc produced around the filament that is burning out away from the adjacent filament. The device may be a permanent magnet or an electromagnet that is excited only for the time for which an arc is likely to occur. The magnetic field may also be produced by one of the filaments. The magnetic field replaces the ionisation screening electrode normally present in such lamps and prevents the arc jumping across from the burnt-out filament to the intact filament.

Title: Removing contaminants from drying plant exhaust gas - where reheating removes organic deposits from heat exchanger
Inventor: WALDMANN GUENTER DIPL ING
IPC: B01D5/00
Filed: 1980-03-14
Abstract: Combustible and depositable contaminants are removed from the exhaust gases from drying plant, e.g. for matchwood, by cooling the gases until the volatile materials condense and bind any entrained dust. The deposits are periodically revaporised and collected at a separate location for disposal, e.g. are deposited in filters which can be burned and used as fuel. Revaporisation may be by hot gas. The exhaust gas can be split into sepd. streams for the initial cooling, which may be by heat exchange with fresh air. The revaporisation can be initiated at a specific pressure difference between exhaust gases with and without the contaminating material. The process is suitable for matchwood mfr., and processes such as veneer drying and paint treatment which produce similar contaminants (terpenes, resins). Atmospheric pollution is reduced, and the risks and expense involved in previous burning-off methods are avoided.
