Title: Coke oven door frame insulation - between inner and outer door frame and thrust plate with compensating latch hooks
Inventor: HELLMANN KARL ING GRAD
IPC: C10B25/06
Filed: 1977-03-05
Abstract: The insulation between the coke oven end walls and the door frames is so designed that certain temp. differential thresholds are not exceeded. The elastic deformability of the various layers of insulation between outer and inner frame, between out frame and thrust plate, and between end lining and brickwork is chosen such that any residual deformations are compensated by elastic deformation of the outer frame and/or of the end lining. If the temp at the thrust plate and the door frames are measured regularly, adjusting screws can be tightened to compensate all deformations caused by differential heating of the frame and of the thrust plates.

Title: Carbonisation or gasification of oxidised coal dust - using controlled supply of hot gas for coal oxidn.
Inventor: SCHUSTER ERNST DIPL ING DR ING
IPC: C10J3/46
Filed: 1977-04-09
Abstract: In the rapid carbonisation and/or gasification (partial or total gasification) of pulverised coking coal, in which the coal is subjected to rapid preoxidation to reduce its caking power, the preoxidation is effected during pneumatic transport of the coal, and the coal is heated to the preoxidation temp. (e.g. 400 degrees C) by direct heat exchange. The process is characterised by the fac that the O2-contg. gas used for both preoxidising and transporting the coal is preheated (pref. to >1000 degrees C) and mixed with the coal in portions such that at most the 0.005 mm fraction of the coal particles (ranging in size from 0 to 0.2, pref. 0 to 0.1 mm) is heated briefly (for 0.1 sec) to a temp. in the plastic range of the coal (e.g. 480-500 degrees C). The process allows the highest possible feed densiy (kg of coal per m3 of gas) to be achieved without significant caking of the coal dust, since the 0.005 mm fraction has the lowest content of caking components.
Patent DE-2717848-A1 (DE)
Title: Continuous stationery envelopes prodn. - using two processing groups carrying out operations including perforating, folding and gluing of paper bands
Inventor: MEIJER GERARD
IPC: B42C3/00
Filed: 1977-04-22
Abstract: The method uses two groups of installations located one behind the other. The first group produces paper bands with conveyor holes on its edges, tear off perforations along the edges and transverse perforations at distances from each other corresponding to the width of the envelopes. At least one part of the paper bands are over-printed. In the second group a number of these bands are simultaneously and synchronised guided lying above each other so that two bands are glued together at their edges into envelopes. The bands after leaving the first group are folded in zig-zag form corresponding to the transverse perforations. They are then stored in that position on support elements and are then conveyed together and synchronised to the second group.

Title: Texturising yarn clearer with tension-responsive thread detector - eliminates high polymer yarn faults by causing tension drop
Inventor: FOGGER JOACHIM
IPC: B65H63/06
Filed: 1977-06-03
Abstract: Faults are removed during the mfr. of smooth or textured filament yarns from synthetic high polymers. During prodn. a fault which may be inherent or caused during the process of treatment, is detected by a device which puts out a tensional signal. This is used to cause a tension-controlled mechanical thread detector to respond by energising a yarn shear. Specifically the device for generating the tensional signal on the appearance of a fault in the thread, forms an obstruction. A yarn build-up of short duration or a frictional peak is set up at this point, and causes a falling off of tension. System eliminates slubs, knots, built up fly which may be present in the supply spools for the prodn. of false twist textured high polymer (e.g. polyester or polyamide) yarns. The process can also be used for yarns textured by blow nozzles followed by stuffer tube from which the banked up yarn is not drawn out correctly.
