20080197317 | Working Fluid For Heat Transfer - Working fluid for the heat transfer, in particular for the heat transfer by heat pipes, containing or consisting of partially fluorinated and/or perfluorinated hydrocarbons and/or perfluorinated polyethers. Preferably, a mixture of pentafluorobutane and perfluorinated polyether is used as a working fluid. | 08-21-2008 |
20090056333 | Working Fluid For An Orc Process, Orc Process and Orc Apparatus - The invention relates to working fluids for energy conversion in a thermal ORC process for combined generation of electrical and heat energy. The heat source used is in particular thermal water. The working fluids used are partially or perfluorinated hydrocarbons and/or partially or perfluorinated polyethers and/or partially or perfluorinated ketones. In one embodiment of the invention, the working fluid used is a combination of 1,1,1,3,3-pentafluorobutane and a fluorinated polyether having a molecular weight of 340 and a boiling point of 57° C. at 101.3 kPa. | 03-05-2009 |
20110162366 | Working Fluid For An ORC Process, ORC Process and ORC Apparatus - Use of working fluids for energy conversion in a thermal Organic Rankine Cycle (ORC) process for combined generation of electrical and heat energy. The heat source used in the ORC process is in particular thermal water. The working fluids used in the ORC process are partially or perfluorinated hydrocarbons and/or partially or perfluorinated polyethers and/or partially or perfluorinated ketones. In some embodiments, the working fluid used is a combination of 1,1,1,3,3-pentafluorobutane and a fluorinated polyether having a molecular weight of 340 and a boiling point of 57° C. at 101.3 kPa, or a combination of 1,1,1,3,3-pentafluorobutane and at least one partially or perfluorinated ketone. | 07-07-2011 |

20140194023 | LAMINATES WITH FLUOROPOLYMER CLOTH - A laminate includes a first layer of a first fluoropolymer. The laminate can further include a second layer of at least one ply of a fluoropolymer fabric overlying the first layer. The laminate can further include a third layer of a second fluoropolymer overlying the second layer opposite to the first layer. The laminate can have a strain of not more than 50% at a stress of 15 MPa as measured by DIN EN ISO 527 with a sample width of about 1 inch, at a clamp distance of about 50 mm, and a speed of about 50 mm/min. Embodiments of such laminates can find applications, for example, as diaphragm membranes, solenoid valves, conveyor belts, or bearings. | 07-10-2014 |

20130180429 | CARRIAGE BODY FOR A RAIL VEHICLE AND METHOD FOR PRODUCING SAID CARRIAGE BODY - A carriage body for a rail vehicle, in particular for a high-speed train, said carriage body having a base and lateral walls that extend upwards on opposing sides of the base. The base and the lateral walls delimit an interior of the carriage body for transporting persons and/or goods. A longitudinal support for transmitting longitudinal forces is located in each transitional region between the base and the lateral walls, said longitudinal support extending in the longitudinal direction of the carriage body. The carriage body has at least one undercarriage support that extends below the base from the one longitudinal support to the other longitudinal support, said undercarriage support extending partly at a distance to the base so that a space for receiving at least one device for operating the rail vehicle is formed between the undercarriage support and the base. | 07-18-2013 |

20130319281 | CARRIAGE BODY FOR A RAILROAD VEHICLE WITH A COUPLING FIXING DEVICE AND METHOD FOR PRODUCING SAID CARRIAGE BODY - A carriage body for a railroad vehicle, said carriage body having the following: a base, two lateral walls, each of which is connected to the base, at least two longitudinal supports, each of which lies in the transitional region of the base to the lateral wall on opposing sides of the carriage body and which extend in the longitudinal direction of the carriage body, and a coupling fixing device for fixing a coupling via which the carriage body can be connected to a carriage body of another carriage. The fixing device is arranged below the base, and a lower face of the fixing device is connected directly to the longitudinal supports via a connection. | 12-05-2013 |
