The wires are shielded to prevent the radiation of fields therefrom into the interior of the vehicle. Fiber optic cable is used to carry signals. A second fiber composite sheet is then laid-up on the first sheet. The two sheets with the embedded wires are placed in a heated mold to form the sheets into the desired finished shape and configuration. The ends of the copper wires and the fiber optic cables are then terminated by connectors so that they may be later coupled to the circuitry of the vehicle. | 08-05-2010 |

20120186320 | METHOD AND MACHINE TOOL FOR THE PROCESSING AND HARDENING OF METALLIC WORKPIECES - A method and a machine tool are disclosed for processing and hardening metallic workpieces. The workpieces are clamped in workpiece holders and are first processed with metal cutting by means of a processing device and are then hardened by means of a hardening device. For hardening, the processed workpiece is first heated by means of a heating unit and then quenched by means of a quenching unit. The quenching occurs by means of a cryogenic cooling medium, e.g., liquid or gaseous nitrogen. Because the processing and hardening of the workpiece occurs in a clamping device, and the fast quenching of the heated workpiece, a high processing quality and short processing and/or cycle times are achieved. | 07-26-2012 |

The tool has a plurality of second supply lines for the cryogenic cooling medium running across the axis of rotation and leading to the blade inserts, the second supply lines each being thermally insulated in at least some sections. A distributor unit connects the first supply line to at least one of the second supply lines for supplying the cryogenic cooling medium to at least one of the blade inserts. The cryogenic cooling medium can be conducted directly to the blade inserts which are engaged with the crankshaft that is to be machined. | 08-09-2012 |
20130177363 | METHOD AND MACHINE TOOL FOR MACHINING OF METALLIC WORKPIECES - In a method and a machine tool for machining metallic workpieces, a cooling device is provided to supply a cryogenic coolant to a first tool and a precooling device is provided to supply the cryogenic coolant to a second tool. The first tool is held in a first chuck and processes a workpiece, with the first tool during processing being cooled via the cryogenic coolant. The second tool is held in a second chuck and will subsequently be used for processing the workpiece. The second tool is supplied via the precooling device with the cryogenic coolant and thus cooled to the operating temperature required for processing. Due to the fact that the second tool is precooled to the required processing temperature, after the change of tools, the processing of the workpiece can be continued immediately. By precooling the second tool during the primary processing time, the total processing time of the workpiece is reduced, providing the machine tool with higher productivity. | 07-11-2013 |
