Patent YU-58884-A (YU)
Title: Device for stone inciseing
Inventor: WRULICH H
IPC: E21C35/187
Filed: 1984-03-30
Abstract: For cutting rock by means of cutting head (1) having its bits (24) cooperating over a limited axial shifting stroke (a) with a cylinder-piston-aggregate, for example a valve (18), it is proposed to intermittently subject the cylinder-piston-aggregate to the action of pressurized fluid, thus exposing the bit (24) during its engaging the rock to percussion forces. During the phases lacking any action of pressurized fluid onto the cylinder-piston-aggregate, the bit (24) shall be pushed into its starting position. This embodiment can be realized with both hydraulic and pneumatic cylinder-piston-aggregates, noting that in case of an embodiment having a hydraulic cylinder-piston-aggregate it is preferred to design this cylinder-piston-aggregate as a valve (18) which simultaneously provides the possibility to expel pressurized liquid via a spraying nozzle (32) onto the mine face.

Patent YU-61791-A (YU)
Inventor: LANG R
IPC: A01G31/00
Filed: 1991-04-04
Abstract: Disclosed is a process for the production of a porous granulated ceramic material with a pore size greater than 1 mm, in which clay is mixed with calcite, quartz sand, dolomite, feldspar, fireclay, kieselgur and/or sepiolite as aggregate material, with water, with a fluidizer and with a surface-active agent and foamed in the usual way. The foamed mixture is subsequently moulded, if required, to form clay mouldings, the mouldings dried at a temperature between room temperature and 200  DEG C, the dried mouldings crushed and sieved, if required, the sieving fines being returned to the starting mixture, and finally the mouldings or crushed mouldings within a given particle-size range roasted at a temperature above 600  DEG C. The porous material thus produced is intended for use as a plant substrate. The starting materials are added to the mixture in given proportions and the mouldings or crushed mouldings with a residual moisture content of 5-25 % are placed in a preheated oven and roasted at a given temperature in the range between 750 and 1050  DEG C. This invention also includes the subsequently manufactured plant substrate, as well as the new use for this product.
