The carbon blocks consist of a carbon paste based on a carbon aggregate such as coke, anthracite, graphite, a cokefiable organic binder such as pitch and optional additives. The carbon paste is introduced into a mould some of the walls of which can move in relation to their initial position and at least one stress sigma n is applied to the said paste along an axis An, then, successively at l...

An odometer device 1 composing two mumeral drums 2, 3, respectively a total distance indicator numeral drum 2 and a trip indicator numeral drum 3, driven by a D.C. electric motor 28 with electronic speed control. An electronic circuit receives signals from a pulse generator mounted on the vehicle drive take-off and compares them with signals produced by a magneto-electric sensor 34 and representat...

The door has an outer door leaf (1), an inner door surface (7), designed as a sheet-metal lining, and a foam insulation (6). The outer door leaf (1) and the inner door surface (7) are connected by narrow sides (2), the aluminium profiles of which engage around the edges of the outer door leaf and, together with a connecting profile of plastic (4), hold sealing profiles (5). In the case of known do...
