Patent DE-3840295-A1 (DE)
Title: Method for protecting centrifugal separators against overspeeding
Inventor: THUERMER REINHARD
IPC: B04B9/10
Filed: 1988-11-30
Abstract: Method for protecting against overspeeding centrifugal separators which are preferably driven with a three-phase synchronous motor with a memory-programmed frequency convertor control. The time base, which is prescribed by a quartz-stabilized circuit, for frequency formation is tested even at low starting frequencies by a computer algorithm during the starting routine by counting out the oscillations of a second independently operating quartz oscillator at a higher frequency. The second testing in the scope of the computer routine is carried out by means of a constant comparison of the frequency set value with the upper value of the working range, both values being stored in a working memory. The third monitoring takes place at the absolutely acceptable limit frequency which is stored in a read-only memory and compared with the frequency set value. When a higher frequency is detected in any monitoring step, the frequency set value is forcibly adjusted automatically by the computer routine to a value which is equal to or smaller than the limit frequency value.

Title: Apparatus for the transport of balls of textile thread, especially balls of wool
Inventor: ENDERLIN ROBERT
IPC: B65G51/02
Filed: 1989-03-07
Abstract: In order to transport balls of wool or of other textile fibres in a line for the production or treatment of these balls, for example between a tie-round machine and a packaging station, a saving of space and labour and a gain in safety are achieved as a result of a pneumatic transport of the balls within pipelines (4). An injector (9) operated by compressed air generates, in the line, an air stream (A) which sucks in the balls (20) at the entrance (5) and which transports them as far as the exit (7). The balls (20) are introduced into the line in a specific sequence, specifically by means of a suction member (6) which has a movable bush (21) laid around the ball. By means of a shut-off member (8) preferably arranged at the exit point of the line, balls can be accumulated in a buffer zone (28) within the line (4) and it is possible to control an ejection stroke which can be different from the ball-feed stroke. <IMAGE>

Title: Sanding machine for parquet floors - has sanding drum inclined at an angle of 10 deg to direction of travel of machine
Inventor: LUSTIG LEO
IPC: B24B7/18
Filed: 1989-07-12
Abstract: The chassis (12) of the parquet floor  sanding machine runs on the supporting wheelsa (14,16,18) in the direction of travel indicated by arrow (32).

Title: Hydraulic roller installation for exchange stand - has hydraulic cylinders with motion pick=up an servo-valves forming interchange unit operating without disconnecting control lines
Inventor: KLOECKNER JUERGEN DR ING
IPC: B21B31/32
Filed: 1989-12-27
Abstract: Hydraulic roller installation for exchange stand in rolling mill for shaped-, precision- or wire-sections, has the novelity that the hydraulic installation cylinders (4,5) with the motion pickup and servo-valves (4b5b) form a cassette-like interchange unit extractable via fixed guides (6,7) from the operational position in the exchange stand (G) to a rest position outside the stand. Complete exchange stand with the roller stands (1) and the roller sets (2) are removed from the roller line.  Pref. after exchanging the stand, the interchange unit is moved via the guides (6,7) into the exchange stand so another operational cycle can commence. In a design variation the guides can be replaced by freely mobile manipulators. ADVANTAGE - Complete exchange stand is removable without having to separate the hydraulic and electrical supply and control lines. This avoids having to make subsequent adjustments, which process would hamper the rolling process.

Title: Monitoring rotatable component esp. rotor shaft - time-dependently measuring oscillatory path of component in radial direction and rotary position
Inventor: NINK AXEL DIPL ING
IPC: G01M1/22
Filed: 1990-10-11
Abstract: The oscillation path in the radial direction of the component is split up into its speed harmonics (7,8) by Fourier analysis. The phase shift (11,13) between the max. of the harmonic(s) and a certain rotary position of the component as well as the amplitudes of the harmonic(s) are determined for at least one speed harmonic.

A difference vector is formed for comparison with a threshold value. A signal is generated if the latter is exceeded. As well as the FFT components, a control unit, a reference memory, a subtractor, a comparator and a display are used. USE/ADVANTAGE - Rapid comparison for detection of component fault.
