Techniques are disclosed related to flushing one or more data caches. The system comprises an enclosure housing a conveyor and a heatable roller. The use of the metal rod to provide a bearing surface in the toggle actuator substantially reduces wear on the actuator, and thus permits the actuator to be made out of a thermoplastic material rather than a thermoset material, thereby effecting a cost savings. The three formers are disposed in the web-fed rotary press in such a that the two distances between the folding planes of two of the formers, which are placed next to each other in pairs, can be modified. The method including fabricating a device on a silicon-on-insulator substrate with first contacts to the devices and wiring levels on a first side to the first contacts, removing a lower silicon layer to expose the buried oxide layer, forming second contacts to the devices through the buried oxide layer and forming wiring levels over the buried oxide layer to the second contacts. The hub disk extends radially inward to the area of the outside circumference of the hub, where it is connected directly to the hub.
