Patent DE-2224905-A1 (DE)
Title: Graphitisation of pitch-impregnated carbon articles - in Acheson furnace using lower layer of pitch-impregnated and upper layer of unimpregnated articles
Inventor: SINKEL FRIEDRICH DIPL CHEM DR
IPC: C04B35/52
Filed: 1972-05-20
Abstract: The furnace pref. is charged with 50-70% pitch-impregnated and 50-30% unimpregnated articles, the mats. depending on the gas concn. and contact time in the hot zone. Owing to the higher electrical resistance of the impregnated articles, the upper zone reaches a temp. of ca. 1000 degrees C before marked coking of the impregnant begins. The gas from the lower zone is cracked in the upper zone so that it ignites and burns with a clear, almost smokeless flame to H2O and CO2 on leaving the furnace. The method eliminates the need for precoking in a round down-draught kiln, and gives better control and reproducible resistance values.

Title: Heat recovery system for firing systems - has heat exchanger for separating toxic substances from flue gases
Inventor: SCHNEIDER CHRISTIAN DIPL ING
IPC: B01D57/00
Filed: 1974-02-11
Abstract: The flue gases in the heat recovery system are cooled to the drew point of the toxic substances and the condensed toxic substances are drained out. If the flue gases have low speed then their speed can be increased after cooling by a fan. The flue gases from a conventional burner pass through a heat exchanger in the flue gas duct. Heat is absorbed in this heat exchanger and the cooled flue gases, which have lost their toxic substance content, are forcibly blown into a smokestack. The ari heated in the heat exchanger is directed to the burner. The heated air can be used also for heating purposes. The toxic substances are drained and collected by the funnel and directed to the collection tank.

Title: Boring cutter with lateral guide - has diagonal lateral guide ribs to ensure high lateral stability
Inventor: ISCHEN GUENTER
IPC: B23B51/00
Filed: 1974-05-09
Abstract: The boring cutter has edges at the front and side to form a lateral stabilising guide which is in contact with the bore wall during machining. Although the width of the guiding edge is reduced on regrinding, the angle of inclination ensures that when the cutter overall length is reduced on regrinding the width is effectively increased to a greater extent than in the case of a straight guide. The boring cutter is used for boring holes into solid metal without using starting centre holes. The end face (3) need not be reground to such an extent as a conventional cutter. The diagonal guides (8) provide a wide support area.
