Abstract: A local area networking apparatus comprises a power stage for connecting to a network cable for carrying carry power and data. The power stage comprises a main current flow path which includes a switch comprising at least one transistor positioned in the main current flow path and a current monitoring apparatus for monitoring current flow in the main current flow path, and wherein the current monitoring apparatus comprises a sensor which is not placed in series with the main current flow path. The current monitoring apparatus can comprise a current mirroring stage which is arranged to mirror current flowing in the main current flow path to a monitoring current flow path. The switch can be implemented as a set of switches.

Abstract: The invention relates to damped elastic supports, comprising essentially, between two bases fixable to assemblies to be supported on one another, on the one hand a flexible wall defining one chamber designed to cooperate with another chamber and, on the other hand, at least one fluid-flow restricting orifice. This assembly is also completed outwardly by two elastic domes of elastomer combined with one mass. The assembly of this mass with another mass and with the damper device and the elastic membranes is calculated so as to permit a certain flexibility to be maintained, both for low frequencies and high frequencies. The invention is particularly applicable to automobile engine supports.

Abstract: The seal is designed to ensure fluid-tightness between the cone and the cup of a conical roller bearing. The seal includes an armature, having a frustoconic bearing surface, fastenable with the cone, a collar stop mounted slidably along the armature and fast to a second bearing surface, and an annular spring mounted in extension on the first bearing surface and supported against the second bearing surface so as to urge these two bearing surfaces constantly into relative axial separation and to be rollable or slidable on the first bearing surface when the collar stop is moved axially with respect to the armature.

Abstract: In a shaft seal assembly for a shaft rotatably mounted in a frame with a ball bearing, the seal includes an elastomer sleeve that bears on a ring fitted over the shaft, the ring in turn bearing axially on a stop. In one embodiment, electrical contact between the ring and the stop on the one hand and electrical contact between the ring and the shaft on the other ground any stray electrical currents in the ball bearings.

Abstract: The invention concerns seals particularly for rotating shafts.This seal, with a flexible membrane in the form of a cupola having an aperture for the shaft to pass therethrough, is characterized by the fact that said cupola has a thickness decreasing from its base to the contact ridge with the shaft, the elasticity necessary for maintaining the contact being obtained from the inherent rigidity of the membrane.

Abstract: A lip sealing ring has a lip engaging a shaft, the lip being at one end of a flexible sleeve which surrounds the shaft and is supported by its other end in a housing. The sealing lip is supported by a pair of stiffening rings, one on the inside and one on the outside of the sleeve, to ensure adequate sealing while allowing the sleeve to be sufficiently flexible to accommodate displacements of the shaft.
