Abstract
Abstract The device includes cables along the path of a vehicle to transmit signals to this vehicle or receive them by induction. These cables are fixed on a band of flexible and elastic material. The cables can thus be fixed to the band in the factory and the positioning of the band with its cables in place can be effected by unwinding from a spool and fixing the band on a support by means of clamps. The device is particularly useful for automatic piloting of metropolitan trains.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
178 words
A device responsive to the movement of a vehicle along said device to emit or receive electrical signals, said device comprising: at least one electrical conductor means, said conductor means extending generally in a direction parallel to said vehicle movement, and said conductor means having spaCed portions deviating laterally from said direction, and responsive to said vehicle movement to produce said electrical signals by induction; and a band of flexible material on which said conductor means is fixed, said band extending continuously in said direction substantially coextensively with said conductor means, said band having upstanding from at least one surface a plurality of pairs of ribs, different adjacent pairs providing different channels for said conductor means, said ribs also extending continuously in said direction substantially coextensively with said conductor means, except for cut-outs permitting said laterally deviating portions to extend laterally from one channel to another, and said band and ribs being constructed and arranged with such flexibility that they can be transported in longitudinally folded or rolled condition, and unfolded or unrolled to extend in said direction.
Claim 2
Independent Claim
178 words
A device responsive to the movement of a vehicle along said device to emit or receive electrical signals, said device comprising: at least one electrical conductor means, said conductor means extending generally in a direction parallel to said vehicle movement, and said conductor means having spaCed portions deviating laterally from said direction, and responsive to said vehicle movement to produce said electrical signals by induction; and a band of flexible material on which said conductor means is fixed, said band extending continuously in said direction substantially coextensively with said conductor means, said band having upstanding from at least one surface a plurality of pairs of ribs, different adjacent pairs providing different channels for said conductor means, said ribs also extending continuously in said direction substantially coextensively with said conductor means, except for cut-outs permitting said laterally deviating portions to extend laterally from one channel to another, and said band and ribs being constructed and arranged with such flexibility that they can be transported in longitudinally folded or rolled condition, and unfolded or unrolled to extend in said direction.
Claim 3
Dependent Claim
54 words
Device according to claim 1, wherein said ribs are shaped by ribs forming between them, near their bases a channel whose cross-section corresponds to the cross-section of the conductor means, and, near their free ends, an entry slot enabling, when the ribs are elastically separated, the insertion of the conductor means into said channel.
Claim 4
Dependent Claim
57 words
Device according to claim 1, wherein said band is positioned on a plate and fixed on said plate by clamps having the general shape of a ''''U,'''' one of the wings of each said clamp passing over the top of the band, whilst the other wing is fixed in one of the lateral edges of the plate.
Claim 5
Dependent Claim
19 words
The device of claim 1, wherein said conductor means is in the form of a plurality of electrical cables.
Claim 6
Dependent Claim
30 words
The device of claim 1, wherein said material is both flexible and elastic and is selected from the group of materials formed of rubber, polyvinyl chloride, other elastomers, and plastics.
Claim 7
Dependent Claim
140 words
An electrical conductor positioning device comprising: at least one electrical conductor means, extending generally in a predetermined direction and having spaced portions deviating laterally from said direction; and a band of flexible material on which said conductor means is fixed, said band extending continuously in said direction substantially coextensively with said conductor means, said band having upstanding from at least one surface a plurality of pairs of ribs, different adjacent pairs providing different channels for said conductor means, said ribs also extending continuously in said direction substantially coextensively with said conductor means, except for cut-outs permitting said laterally deviating portions to extend laterally from one channel to another; and said band and ribs being constructed and arranged with such flexibility that they can be transported in longitudinally folded or rolled condition, and unfolded or unrolled to extend in said direction.
Claim 8
Dependent Claim
140 words
An electrical conductor positioning device comprising: at least one electrical conductor means, extending generally in a predetermined direction and having spaced portions deviating laterally from said direction; and a band of flexible material on which said conductor means is fixed, said band extending continuously in said direction substantially coextensively with said conductor means, said band having upstanding from at least one surface a plurality of pairs of ribs, different adjacent pairs providing different channels for said conductor means, said ribs also extending continuously in said direction substantially coextensively with said conductor means, except for cut-outs permitting said laterally deviating portions to extend laterally from one channel to another; and said band and ribs being constructed and arranged with such flexibility that they can be transported in longitudinally folded or rolled condition, and unfolded or unrolled to extend in said direction.
