Filed: 1979-05-12
Abstract: The end disc (13) of the warping drum, the said end disc being connected fixedly in terms of rotation to the drum shaft (1), carries a worm (31). This is in engagement with a worm wheel (16) on a threaded sleeve (15) provided with two oppositely directed thread portions (17, 18). The threaded sleeve (15) surrounds the drum shaft (1), but is rotatable relative to the latter. Seated on each of the thread portions (17, 18) is a threaded ring (19 and 20). Articulated on the latter in a star-shaped manner is a respective link (25) for each cone blade (11). The pairs of links assigned to a respective cone blade (11) are articulated on the cone blade at a common axis (26). Telescopic guides (29, 30 and 27, 28) stabilize the threaded rings (19 and 20) against corotation when the threaded sleeve (15) is rotated. When the threaded sleeve (15) is rotated, the axial spacing of the threaded rings (19, 20) and consequently the height of the isosceles triangle formed by the pairs of links changes. The cone blades (11) are thereby pivoted about their pivot axes (12) and their angle of incidence is varied. <IMAGE>

Title: Vibrating conveyor belt for sorting agricultural crops - has sharply inclined lower section of upper belt for good separation with no back-log
Inventor: GERLACH GUENTER
IPC: B07B13/11
Filed: 1979-07-21
Abstract: The endless conveyor belt (30) moves inclined over guide rollers (21,22). It is designed so that the inclination of the upper vibrating run (32) of the belt increases considerably at the lower belt end (30b) where the vibration impact is minimal. This ensures that when the mixture of e.g. sugar beet and gravel is fed onto the conveyor belt the lighter waste particles are carried up on the belt whilst the heavier crops roll down against the running direction of the conveyor. At the more sharply inclined lower section of the belt they drop off into the collector receptacle ensuring no backlog builds up.

Inventor: EIBL-VOGT ALFRED ING GRAD
IPC: H03C3/09
Filed: 1979-08-16
Abstract: The circuit generates an output voltage between two limiting frequencies. The output voltage of an oscillator (01) is compared with a reference voltage (UB) in a frequency and phase comparator (TH). The frequency (f3) of the reference voltage is determined by a synthesiser (03) which is supplied by both limiting frequencies (fa,fe), via an adjustable memory. The control voltage (U2) for the tunable oscillator is analogously generated. A change-over switch (SAI) has pref. a series-connected integrator (IN) with timing element (C,R). At the starting low output frequency (f1) of the oscillator an auxiliary voltage (U1) is applied for charging the integrator RC-element. The setting signal (U2) tunes the oscillator until the desired limiting frequency has been reached. The integrator may contain a differential amplifier, supplied with a reference voltage derived from the auxiliary voltage and forming a fraction of the same. This reference voltage may be one half of the auxiliary voltage.

IPC: G01S17/58
Filed: 1980-02-29
Abstract: The optical measuring device is build as a compact unit inside the system (1) whose velocity component it is required to measure. A coherent beam of light (4) e.g. laser beam, is emitted by a light source (2) and is aimed at an optically transparent glass block (6) having highly reflective mirror surfaces (7,7') so that after being reflected backwards and forwards N times, it leaves the block (6) at some point of low reflection as a light beam (4') again. After leaving the block (6), it is superimposed on part of the original light beam (5) which is stopped out of the coherent light source (3) by means of partly translucent mirrors (8,8') placed in front of the transparent glass block (6). An optical intensity detector (10) e.g. photodiode or photomultiplier is placed in the region of interference (9) so that if the system (1) is set in motion in the direction of the light source (2), a wave length change takes place, due to the Doppler effect. The phase difference in the interference region (9) is regi tered by the detector (10) and is proportional to the velocity component U of the system.
