March-7, Such rotors have been previously provided with bushed bearings because the known ball bearings could not beleasily placed iii-electric counters. To remedy this', the present invention consists in that the inner race is constituted by the shaft itself and that 'the outer race and a stationary 30 signs of reference refer to similar parts.

SAP Significant new features: Concrete frame design has been enhanced to improve the smoothing of P-M-M interaction surfaces in those rare cases where they become non-convex due to kinks in the P-M curves.
In processing of rubber or rubber-like com-- pounds, such compounds are sometimes mixed and rolled in a rubber mill which rolls the combound into the form of a sheet. The sheet is sometimes cut into a continuous strip which is drawn from the mill. In the past, it has been ciliilcult to gage the thickness of the strip as it is taken oil the mill in order to keep the strip from being too thick.
Innovative Infrastructure Solutions. DecemberCite as. In particular, isolation has been extensively applied for pier and abutment protection, in order to strengthen bridges against earthquakes.
Tico structural bearings provide a maintenance-free resilient barrier for the isolation of structures from ground borne noise and vibration. In addition, our low-friction sliding bearings are designed to accommodate large laterial movements in structures, particularly when associated with high vertical loads.

Articulation is the term for the configuration of bridge supports and choice of structural bearings that provides the necessary restraints to the superstructure whilst at the same time providing freedom to some displacements and rotations in order to avoid unnecessary forces on both the superstructure and substructure due to constraint. A range of different bearing types is available. Selection of the appropriate type and specification of the forces they must resist and displacements they must permit is a key responsibility for the structural designer.
This is a division of application Ser. This invention relates generally to roller bearing cages and, more particularly, to roller bearing cages of "sigma" configuration. Roller bearings commonly employ separators, retainers or cages to maintain separation and alignment of the rollers. Although the terms are frequently used interchangeably, the term "cage" is often used to describe a device that retains the rollers both radially and axially.
