Patent DE-2441068-A1 (DE)
Title: Indicator control for barrel transporter - using a paired magnet system of opposed polarity
Inventor: HALLER EGON
IPC: B65G47/49
Filed: 1974-08-27
Abstract: Barrel transporter indicator control may consist of five rows of divided electromagnetic indicator probes. The electromagnets in rows (1, 2 and 5) have similar polarity, whilst the magnets in remaining rows (3 and 4) are of opposed polarity. This produces a considerably smaller raster size without employing a strip contact in row (2) through the opposed magnets in adjacent rows (1 and 3), since the magnetic fields of both magnets for this strip contact are of opposite sense, and cancel each other. A similar occurrence prevails when the strip contact is positioned in one row (3 or 4), in which case the contact is placed between magnets of similar polarity.

Title: Additional drive wheel for tractor - with sprung connections between hub and rim to negotiate obstructions
Inventor: MOLITOR AMBROSE LEO
IPC: B60B9/06
Filed: 1975-02-07
Abstract: The additional wheels are bolted to extensions to the rear axles, in parallel settings to the rear drive wheels. They prevent the tractor from sinking into soft ground.
