Patent DE-3049019-A1 (DE)
Inventor: KRONMUELLER HEINZ PROF DR
IPC: G01P5/18
Filed: 1980-12-24
Abstract: The fluidised bulk material (3), which flows downwards on a fluidising bed (2) is marked at the start of a measuring section set out by electrodes (15a, 15b) by a marking in the form of a local change in the weight of bulk material per unit area on the conveying surface loaded with the bulk material, and/or in the density of the bulk material (3). The mechanical marking can be an empty position in the stream of bulk material, which position is produced by a short term compressed air jet from a nozzle (1) or by rapid immersion of a dipper or rocker. The marking is detected capacitively by the electrodes (15a, 15b), to which impedance transformers (10) are connected. In a modified method, a local electrical charging of the bulk material can also be used as marking. In this case, the electrodes expediently dip into the stream of bulk material, an electric charge being applied to the bulk material (3) for a short while by the first electrode and the charge being detected by the second electrode. The methods permit an accurate determination of the average rate of flow without the bulk material (3) being contaminated in the process, and are applied in the manufacture of scales in order to determine the rate of flow, from which the mass or the weight of the bulk material conveyed per unit time can be determined. <IMAGE>

Title: DC magnet
Inventor: ZIEGLER ROLF DIPL ING
IPC: H01F7/16
Filed: 1981-03-20
Abstract: The invention relates to a DC magnet having a coil former (2) which carries the winding and is surrounded by a sheath (4). The ends (11, 28) of the sheath (4) are formed by pole discs which transmit the magnetic flux to a core (8) which is surrounded by the coil former (2) and to its associated moving armature (10). At least on the end (11) associated with the armature (10), the magnetic flux is transmitted by a plurality of pole discs (5, 6) which are electrically insulated from one another, so that an increased initial flux is built up, eddy currents which impede the building up of the magnetic field being prevented in the pole plates (5, 6). The attraction time of a DC magnet (Fig. 1) of such construction is considerably less than in the prior art. The attraction time can be reduced to approximately 1 millisecond by reducing the moving mass of the armature by attachment of an inner cone (26), by an axial slot (27) in the sheath (4) and by a radial slot in the core (8) and/or in the armature (10). <IMAGE>
