An automatic vehicle monitoring system utilizing a plurality of spaced magnetic fields disposed along a vehicle path. A vehicle mounted sensor produces electrical signals in response to the presence of the magnetic fields. These signals are processed to discriminate against noise and to extract therefrom information concerning the location of the vehicle.

Automatic vehicle monitoring system

The invention is a simplified roller-type apparatus for laminating articles in sheet form with transparent plastic laminating film. It comprises a heating station for heating the work and a pair of pressure rolls for bonding the film to one or both sides of each article. The heating station comprises a pair of vertically opposed flat plates that are separable to permit the work to be inserted between them, and means for heating the plates so that they act as sources of heat for activating the adhesive layer of the laminating film. In the preferred embodiment, the lower plate is fixed and the upper plate is mounted for vertical movement relative to the lower plate. The two plates also act as guides for directing the heated work into the nip formed by the pressure rolls.
