Title: Coke wharf for coke oven plant - with central coke quenching car track over partly symmetrical inclined ramps
Inventor: ISERMANN FRIEDRICH
IPC: C10B39/18
Filed: 1978-07-10
Abstract: A coke wharf for coke oven batteries is an inclined ramp from which the coke can be transferred to a belt conveyor.

Title: Raking arms shaft support - by radial bottom bearing in air trapping cavity and top Cardan joint to drive motor
Inventor: KRONENBERGER GOTTFRIED DR ING
IPC: B01D21/00
Filed: 1978-07-31
Abstract: The vertical hollow shaft for the raking arms of a sludge separator in a sewage treatment plant has at its bottom end a separate hollow section in which air is trapped. A cylindrical guide rests at the bottom of the separator tank and acts as a radial bearing for the bottom end of the shaft. The top end is coupled to the drive motor through a Cardan joint. The cavity is large enough to ensure that the air trapped in it, though compressed by the hydrostatic pressure, keeps the sludge clear from the bearing surfaces. The severe sealing problems of an outside bearing are thus overcome.

Title: Moving articles transfer system - with endless belt pairs and toothed vertical disc for synchronised transfer
Inventor: ANDERSSON NILS OLOF BIRGER
IPC: B65G47/84
Filed: 1979-04-26
Abstract: In a transfer system of articles, esp. the inner boxes of matchboxes, to a conveyor, the inner boxes are centred and moved along by a pair of endless belts which contact their sides.
