Abstract
Abstract In a mobile track liner wherein the track position is indicated by the relative position of a reference line to an indicating element associated and cooperating therewith, a radiation signal is generated which corresponds to this relative position, and the signal is transmitted to a signal-receiving device by a device arranged transversely of the track and responsive to the radiation signal.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
112 words
In an apparatus for indicating and establishing the position of a track, which is mounted for mobility on the track: 1. a reference; 2. a mobile apparatus part guided along the track in fixed relation thereto whereby the apparatus part measurably indicates the track position, a. the reference and the apparatus part cooperating to indicate and establish the position of the track; 3. a device arranged in fixed relationship to the apparatus part during the track position indication and responsive to a radiation signal corresponding to parameters determining track position for receiving and transmitting the the radiation signal, and 4. a device for visibly reproducing the track position determined by said parameters.
Claim 2
Dependent Claim
112 words

Claim 3
Dependent Claim
38 words
a mobile apparatus part guided along the track in fixed relation thereto whereby the apparatus part measurably indicates the track position, a. the reference and the apparatus part cooperating to indicate and establish the position of the track;
Claim 4
Dependent Claim
38 words
a mobile apparatus part guided along the track in fixed relation thereto whereby the apparatus part measurably indicates the track position, a. the reference and the apparatus part cooperating to indicate and establish the position of the track;
Claim 5
Dependent Claim
