Patent ES-477035-A1 (ES)
Title: An improved freewheel, equipped with dual rotation transmission.
IPC: B60P/
Filed: 1979-01-20
Abstract: Our invention enables the four-wheel drive of the dumper lorry to be engaged automatically at the point when the wheels slip from the driveshaft, this engagement occurring regardless of the direction in which the wheels are turning, i.e., of the direction in which the driver has chosen to move. This solution ensures that the dumper lorry does not seize under any circumstances, thus requiring no help from other machines and not interrupting the pace of the excavation works. The automatic engagement is achieved because the output shaft of the gearbox transmits a rotation to a cogged ring in the shape of a plate, with a lower transmission ratio than the unit; within which a specially-shaped body rotates coaxially to it and receives the rotational movement of the front shaft.

Title: Method of detecting flaws on surfaces.
IPC: G01N21/952
Filed: 1979-08-08
Abstract: This invention is an improved method for scanning for flaws on a surface utilizing dynamic correction.
