Patent DE-2613547-A1 (DE)
Title: Mixing various types of grain in a vacuum vessel - to which air is admitted at the bottom
Inventor: BAUMANN RUDI
IPC: B01F33/40
Filed: 1976-03-30
Abstract: A closed vessel in which >=2 types of grain are to be mixed is partially evacuated and then atmospheric air is introduced at the bottom. This produces less damage to the grain, and produces less dust, than would a mixer with mechanical stirrers. The air can be introduced in puffs. The closed vessel can taper conically downwards and the air be introduced at the apex of the cone. Suction can be used to bring the various grains into the closed vessel ready for mixing.

Title: Thermal regeneration of laden adsorbents e.g. Kieselguhr - by predrying and heating in separate appliances
Inventor: VINKEN JOSEF
IPC: B01J20/34
Filed: 1977-04-20
Abstract: In the thermal regeneration of laden kieselguhr and similar absorbents (alumina) the kieselguhr material which is normally supplied in a wet condition is predried and then heated to a temp. at which the adsorbates is vapourised.

Title: Seismic subsoil investigation - using two signals forming complementary pair of binary code
Inventor: EDELMANN HANS A K DR ING
IPC: G01V1/00
Filed: 1977-09-17
Abstract: In a seismic investigation of the subsoil, signals consisting of coded subsections are transmitted to geophone detectors where correlators produce seimograms. To code the subsections they are designed as elements of a binary (or quaternary) system. Each detector array receives at least two signals, the subsections of which form a complementary system. The arrangement results in an effective suppression of the correlation noise on the side wings of the so-called Klauder-wavelets. The waveform which is a vertical stack of the autocorrelation functions of the individual bit elements saves much time.

Title: Model or toy motorway installation - has control system providing steering and speed control through changes in polarity and voltage
Inventor: NEUHIERL HERMANN DIPL CHEM DR
IPC: A63H18/16
Filed: 1978-04-21
Abstract: The toy motorway has track sections, vehicles and a control installation. The vehicles are steered through the control installation from one side of the track to the other and can be influenced in their speed from standing still to their top speed.

Through the direction of rotation by switching in a clutch device the front wheel is steered either to the right or the left. One or both rear wheels independent of the direction of rotation of the motor are driven only forwards. A clutch between the motor shaft and rear wheel or rear axle goes into neutral when the vehicle is pushed. A defined delay is achieved between the time of change of direction of motor rotation and the time of movement of the front wheels by a special transmission system.
