Adjacent to the information vehicle there is an arrangement, including on one side an illuminating device and on the other side an optical sensing device for the signals. Furthermore means are provided by which the signals from the information vehicle are converted into pulses processed by a TV receiver. Displacements of the vehicle in the direction perpendicular to its plane are compensated for on the basis of optical signals.

The information track has a strip-like control track for compensating for vertical displacements.

Abstract: A gas-oil drive for forward and reverse mechanical adjusting movements. Gas, which is available for every direction of movement of an adjusting drive at a pressure greater than atmospheric pressure, conveys its pressure in a pressure tank to control oil which flows to an adjusting device for carrying out a control operation. For both oppositely directed adjusting movements of the gas-oil drive, a single pressure tank for delivering control oil under pressure to the respective corresponding position of the adjusting device, and a single unpressurized container for receiving expelled, unpressurized control oil are provided. The unpressurized container is located above the level of the pressure tank, and a bore on the unpressurized container is connected with a bore on the pressure tank by means of a control oil line in which is located a check valve which closes in a direction of flow toward the unpressurized container.
