Title: Pulsed welding system - using auxiliary pulse for resistance measurement and welding energy adjustment
IPC: B23K11/24

Title: Metallurgical coke prodn. from coal agglomerates - produced using heat-treated coal tar as binder
Inventor: MUNNIX RENE
IPC: C10L5/04
Filed: 1980-04-03
Abstract: Prodn. of metallurgical coke (esp. for use in blast furnaces) is carried out by agglomerating particulate coking or non-coking coal and introducing the green agglomerates into a coke oven together with particulate coking coal.
