Title: Coke oven door lifting mechanism
IPC: C10B25/14
Filed: 1980-07-04
Abstract: A lifting mechanism (A) for the feed door of a horizontal chamber coke oven can be tilted at its upper end about a horizontal shaft (16), which is parallel to the door opening (2) of an oven chamber (1), at an angle support (14), which can be moved to and fro in the direction of the oven chamber (1), by means of an hydraulic piston and cylinder assembly (17) the movement of which is controlled by a bidirectional counter (21) which counts a predetermined number of pulses produced by a pulse generator (22) in dependence on the travel of the assembly (17). The count of the counter (21) is proportional to the tilt position of the tilting part (13) and thus to the actual inclination of the door opening (2). Before the feed door (3) is reinserted into the door opening (2), the hydraulic cylinder (17) is moved out and the bidirectional counter (21) counts down until the initial count corresponding to the actual inclination of the door opening 2 has been reached again. <IMAGE>

Title: Powder classifier
Inventor: WHIDDETT GREVILLE NICOLAS
IPC: B07B11/06
Filed: 1982-11-25
Abstract: Powder suspended in an air stream may be classified into coarse and fine fractions by subjecting it simultaneously to centrifugal and centripetal forces. In a classifier having rotating discs, with no guide vanes between the disc, and an axial outlet, some nibs or larger particles may be carried over by the increasing velocity of the air stream as approaching the axis of rotation. In the construction shown, powder fed from a hopper 3 is suspended in an air stream and carried to a zone peripheral to rotating discs 7, 8 and 9. The air is drawn off, with a fine powder fraction, via a hollow shaft 4. In order to avoid the carry over of larger particles by the accelerating air stream, the discs 7 and 9 are tapered at 14 to make the cross-section of the air flow passages between the pair of discs 7, 8 and 8, 9 substantially constant over the inlet zone. <IMAGE>
