Wireless Local Area Networks

A press, including a frame, a pair of rigid side structures, means for pivotally connecting the side structures to said frame, a pair of rotor assemblies having confronting faces arranged at an angle to each other and defining a pressing zone, each of the rotor assemblies being mounted for rotation in a respective side member, means interconnecting the side structures to one another and serving to apply yieldable force to urge the side structures toward one another, the improvements basically comprising means for adjusting the pivotal connecting means to vary the pressing action of the rotor assemblies, and a hydrostatic bearing means, which may be used in association with an annular thrust bearing, for minimizing the friction between the rotor assemblies and the side structures.
