A suspension assembly comprising a combination torque rod and sway bar is shown and described. In a preferred embodiment, the assembly comprises two arms that are pivotally coupled at a first end to a first and second end of a crossmember, the second ends of the arms being coupled to a vehicle axle. By providing a suspension assembly in this manner, the arms function as torque rods to absorb the l...

Containers having a fastening base are known which can be locked via a connecting piece into insertion apertures which are arranged on a lid which is mounted on the rear of the casing. This fastening base support which is situated outside the centre of gravity of the container causes vibrations and increases the level of load on the fastening base. To avoid these disadvantages, a container is prop...

A method for repairing furnaces (1), particularly those adapted for glass-melting. The first step consists in unloading the molten glass (14) at a temperature that is close to the melting temperature; this is followed by the second step, that consists in monitoring the inside of the furnace (1), keeping the furnace (1) at a medium-to-high temperature to facilitate draining of the molten glass (14)...
