Title: Local error detection apparatus for satellite-based navigation system
Inventor: SCHNIEDER E PROF DR-ING
IPC: G01S5/14
Filed: 1997-01-08
Abstract: The apparatus includes at least two antennae (A2, A3) arranged on a vehicle or a vehicle convoy for a reception of at least one satellite signal for localization purposes. The antennae are arranged at a distance (3) from each other, which is so large, that a local orientation error does not affect both antennae simultaneously. The vehicle determines the position of the other antenna (A3) based on the local orientation result derived from the antenna signal and the spatial curve travelled by it, as well as the distance between the antennae, and compares this local orientation result with the local orientation result derived from the antenna signal. The vehicle rejects the local orientation result of at least the antenna lying in front in a drive direction, if the difference of the local orientation results derived for the same antenna deviates by an amount which is equal or larger than a predetermined threshold value.

IPC: B65G47/72
Filed: 1998-02-05
Abstract: The invention relates to a method for distributing a flow of bulk material amongst several sub-flows. The method is characterised in that the flow of bulk material accumulates in an essentially vertically oriented pipe; in that the sub-flows branch off from the accumulated flow of bulk material and in that the sub-flows are led over a horizontal or slightly inclined section so that a bank forms inside and blocks the sub-flow. The bulk material is then removed from the sub-flow by vibration, the bank block being constantly replaced by the particles which slide down correspondingly. The invention also relates to a device for distributing a flow of bulk material amongst several sub-flows, comprising a supply container (1) located upstream. At least one essentially vertical distribution pipe (2) is provided downstream of said supply container. The distribution pipe (2) has at least one part which branches off (3), with a branching-off pipe (31) connected thereto. Said branching-off pipe (31) has a section (32) which is positioned at a slightly smaller angle downstream than the angle of the bank of bulk material.
