Title: Coal washing system setting tank bottom - is made of elastic material resting on supporting grill rigidly fixed to tank framework
Inventor: BOESKER EWALD ING GRAD
IPC: B03B5/18
Filed: 1976-12-04
Abstract: The elastic settling tank bottom aims at reducing the incidence of clogging by coal particles caught in the required perforations of the bottom and at reducing turbulence. The settling tank bottom is made of an elastic plastic or rubber material and rests on a supporting grille (6) fixed rigidly to the framework of the tank structure. The edges of the bottom (1) are clamped down on frame (2) by counter frame (8). During the lifting stroke of the pulsating water mass the perforated bottom bulges out upwards and the coal particles receive an acceleration in upward direction. During the subsequent sucking stroke of the pulsating water mass the perforated bottom due to an elastic diaphragm action returns to its original position, where it rests on the supporting grile, quicker than the coal particles, so that when these touch the perforated bottom, the perforations are in their true undistorted size.

Inventor: FISCHER HERMANN
IPC: B41F13/21
Filed: 1977-01-17
Abstract: Bearing ring attachments with impact-absorbing materials, for example hard rubber, are used to increase the service life of bearing rings used on forme or rubber-covered cylinders of offset rotary printing machines and to damp the impact loads occurring, in particular, when the clamping gaps are passed over. The core (13) of the bearing ring on the axle stub of a cylinder (1) can be made of metal, whereas the outer ring (14) arranged on said core consists of hard rubber. Instead of the fixed connection of the core (13) of the bearing ring to the outer ring (14), a releasable connection can also be provided, or the core or inner ring can consist of impact-damping material and the outer ring of metal. A further design consists in the fact that an impact-damping bearing ring (21) is made up of a fixed metal disc (22) and a further disc (23) connected thereto and consisting of an impact-damping material. The outside diameter of the further disc (23) is greater than the outside diameter of the disc (22). In this arrangement, the diameter of the disc (22) is equal to the diameter of the partial circle of the driving gears of the cylinders. <IMAGE>
