Title: Centrifugal sorting system for granular material - passes thin layer of material along deflecting flow channel curving through angle of 45-180 degrees
Inventor: RUMPF HANS PROF DR ING
IPC: B07B7/086
Filed: 1977-03-10
Abstract: The continuous centrifugal sorting appts. for streams of granular material includes a flow channel (2, 3) for deflecting the grading flow which is curved inside with a deflecting angle of about 45 deg. to above 180 deg. so that the grain flow is directed in a thin layer into a sorting stream which is diverted in the grading zone (7) and which on the inside adjoins a curved inner deflector wall (1) along the inner above-mentioned deflector angle along which it is not guided by any wall adjoins an outer stream (9) which draws off the coarse fractions. This grading stream runs parallel to the inner deflector wall and the ratio of the radii from the outer to the inner curvature of this current is less than 5:1. At the beginning of the curve of the inner deflector wall the speed of the stream is at least half that of the sorting stream at the feed-in point. After bein split up by the centrifugal force the fine particles are drawn off with the downwardly flowing stream and at most a part of the outer stream and the larger fractions are drawn off with the outer stream and at most a part of the grading stream. The direction of the material stream differs from the sorting stream inside the flow channel by less than 45 deg.

Title: Parallel power packs protection system - ensures that when one power pack is overloaded, it is disconnected until its temp. drops
Inventor: DIETER HANS DR ING
IPC: H02H5/04
Filed: 1978-03-17
Abstract: The loading and temp. of each current limited power pack (1, 2, 3) are reported to a control unit (7). When a maximum load is reached by one power pack, the system ensures that it is held at its load limit until all power packs have reached their limits. Then, if the load limit or critical temperature of a power pack is exceeded it automatically switches itself off and reports it to the control unit. The latter reconnects it when its temp falls below a certain limit. All power packs are disconnected when the total load exceeds a certain maximum.

Title: Optical safety system for press - has sub-system to periodically produce artificial fault condition by interrupting optical couplings using relay to actuate counter
Inventor: NAGAI SHUNICHI
IPC: G07C11/00
Filed: 1978-06-24
Abstract: A press has an access opening guarded by an optical safety system including a subsystem which periodically generates an artificial fault condition. This checks that an emergency stop signal is generated when several optical couplings (2a, 4a) guarding the opening are interrupted. A relay contact is opened when the press platen rises, i.e. when no guarding is required. This starts a counter which interrupts the emitter and receiver voltages the respective optical couplings. The press is stopped if any one interruption does not produce an emergency signal.

Title: Production of calibration gases with precise moisture content - using inert carrier with excess hydrogen or acetylene to which precise quantity of oxygen is added and mixt. passed over catalyst
Inventor: HAMMER JOSEF
IPC: C01B5/00

Abstract: A precise, defined amt. of water vapour is created in an inert gas stream (e.g. N2 or A) by introducing an excess of H2 or C2H2 and then adding a carefully measured quantity of O2. Systems for measuring O2 are known and very precise. The mixture is then passed over a heated catalyst bed there the O2 and H2 are converted to H2O and the precise amt. is controlled by the amt. of O2 present. This allows the prodn. of a very precise amt. of H2O in the mixture. Used for calibrating instruments which measure gas moisture content. Provides an accurate system for supplying a precise calibration gas stream.
