Abstract: A portable device for monitoring the wear of a tire and the geometry of a wheel set of a vehicle has a probe for measuring a depth of each tread groove of a tire, a display, a symbolic representation of a set of wheels, and indicators. The device includes a control system for processing and calculating measurements, reference values and compared values relating to rate of wear and the condition of the geometric state of the tire. Resulting calculations and comparisons are displayed on the display and indicators are activated based on the calculations and comparisons made.

Abstract: The invention is concerned with a retaining arrangement for a bearing of an electric motor, the retaining arrangement comprising a resilient element and a bell ring.The resilient element comprises a securing ring having a peripheral anchor rim portion which, in transverse cross section, has two branches, namely an outer branch and an inner branch. The outer branch carries anchoring arrangement, while the inner branch is interrupted by slots and carries securing fingers at an axial distance from the zone in which the two branches are joined.The invention is applicable to an electric motor for a heating system.
