Title: Method and device for continuously conveying hard, particulate material
Inventor: RICHTER JOHAN C F C
IPC: B65G53/46
Filed: 1981-05-29
Abstract: A method and a device for transferring hard, particulate material, for example coal, are devised. A high-pressure transfer device (20) with a specially designed screening wall (42) is used to achieve this. The high pressure transfer device (20) has a rotor (21) which is provided with pockets, two (22) of which are continuous in a diametral direction and are perpendicular to one another. A casing (23) encloses the rotor (21) and has four apertures (24-27), which are distributed around its circumference. The rotor (21) or the apertures (24-27) are provided with a screening wall (42) in order to screen out particles which are larger than the prescribed size as they are passed through the device (20). The screening wall (42) is preferably assigned to one of the apertures (24-27) of the casing (23), and injection nozzles (40) are provided which spray compressed liquid against the screening wall (42), in order to flush out any particles which may have been deposited there and to prevent damage to the screening wall (42). Activation of the fluid injection nozzles (49) is timed to match the rotary movement of the rotor (21). Another embodiment has a screening wall (75) made of rods (76) which have square or circular cross-sections and are arranged in the enlarged central region of each of the pockets (22). <IMAGE>

Title: System for washing out residual concrete
Inventor: RIKER RUDOLF
IPC: B03B5/56
Filed: 1981-06-19
Abstract: The invention relates to a system for washing out residual concrete, in the case of which the material to be washed out is fed to one end side of a mixing trough in the form of a half-shell and is conveyed, by agitating and conveying tools, to the other end side and, from there, is discharged via scoops, and the rinsing water flows through the basin in countercurrent and is discharged with the cement slurry on the solids-supply side. The aim of the invention is to improve the functioning such that the spray water is sprayed into the scoops via spray nozzles/nozzles and cleans these or reduces caking, and that the discharge chute has a window for the discharge of water and, if appropriate, the water level in the basin is raised above the shaft centre, this resulting in a defined bearing arrangement and sealing, for which purpose the invention has means and solutions.

Patent DE-3131673-A1 (DE)
Inventor: OBERHANS JOHANN
IPC: G01B3/00
Filed: 1981-08-11
Abstract: A digital, bow-type measuring instrument is disclosed which provides rapid adjustment of the position of a measuring bolt with respect to an anvil over the entire measuring range. The instrument is used by rapidly translating the bolt into position such that the object being measured is positioned between the anvil and the bolt. Thereupon, the bolt is locked in position with the aid of a locking system so as to fix the measuring bolt in position with great rigidity while applying a predetermined measuring force to the bolt. In this way, an instrument is provided which makes possible precise measurements of heavy or fixed objects by means of a bow-type measuring instrument which allows rapid shifting of the measuring bolt.
