Abstract: A method, computer program and system for performing a find and replace editing operation of a text start-ing from a couple of initial find and replace expressions provided by the user, applying each rule defining admissible inflected forms of the initial find expression and the initial replace expression, to the initial find and replace expression to identify all the derived couples of find expression and the replace expression which are valid for the rules. The find expression and the replace expression of the derived couples correspond to inflected forms of the initial find and replace expressions. Then, for each match in the text of the find expression of the derived couples, proposing to the user the derived couples for replacement in the text. The user interface is done through the usual graphical user interface of a text editor or through a text based terminal user interface. The find and replace operation may be passive through the execution of a program including find and replace commands or interactive by asking the user to give his choices during the execution of the program.

Title: Membrane electrode assembly for a low-temperature fuel cell and method for its production
Inventor: EGMEN AYHAN
IPC: H01M4/88
Filed: 2006-12-16
Abstract: The invention relates to a low-temperature fuel cell and to a method for producing the same, having a diaphragm and two electrodes arranged thereon, each comprising a diffusion layer and a carbon carrier layer with a catalyst.  It is characterized by the fact that at least one diffusion layer and the diaphragm are adhesively bonded to one another via locally defined joins, wherein the locally defined joins make up a maximum of 30% of the interface to be connected. The joins are in this case not two-dimensional, but are locally defined, in particular punctiform or linear. This additional adhesive bonding, for example consisting of Nafion~, results in extensive interleaving of the polymer electrolyte diaphragm and the electrode, since it can advantageously reach further through the individual carbon carrier particles as far as the diffusion layer. The extension produced by the swelling of the polymer electrolyte diaphragm is now markedly reduced by the interleaving with the electrode. Tears within the carbon carrier layers therefore advantageously no longer arise as easily.

Title: Tubular patent foramen ovale (pfo) closure device with catch system
Inventor: CALLAGHAN DAVID J
IPC: A61B17/12
Filed: 2007-03-29
Abstract: The present invention provides a device for occluding an anatomical aperture, such as an atrial septal defect (ASD) or a patent foramen ovale (PFO). The occluder includes two sides connected by a central tube. The occluder is formed from a tube, which is cut to produce struts in each side. Upon the application of force, the struts deform into loops. The loops may be of various shapes, sizes, and configurations, and, in at least some embodiments, the loops have rounded peripheries. In some embodiments, at least one of the sides includes a tissue scaffold. The occluder further includes a catch system that maintains its deployed state in vivo. When the occluder is deployed in vivo, the two sides are disposed on opposite sides of the septal tissue surrounding the aperture and the catch system is deployed so that the occluder exerts a compressive force on the septal tissue and closes the aperture.

Abstract: At least one section of the screw (11) has a wear-protection layer (13) and at least one other section of the screw preferably has an anti-friction layer (18). In a solid rod (11'), a bed (12) for the wear-protection layer (13) is first formed, and in this the wear-protection layer (13) is then applied, and finally the interstices (14) between the screw flights (15) are formed. According to the invention, the wear-protection layer (13), for example composed of tungsten carbide, is applied by build-up welding, and the interstices (14) are formed with lateral separation (16, 16') with respect to the wear-protection layer (13). For production of the anti-friction layer, the dimension of that/those section(s) of the screw (11) where the anti-friction layer, e.g. composed of molybdenum, is to be applied is reduced below specification, while providing lateral separation (19) with respect to the wear-protection layer. The anti-friction layer is then applied in the under-dimensioned region (17). Finally, the screw (11) is brought to the specified dimension.

Title: A method of managing unanswered calls using a network-based service
Inventor: DOULTON DANIEL MICHAEL
IPC: G06Q10/00
Filed: 2008-01-09
Abstract: A network based service manages unanswered calls to telephone numbers. The network picks up the call before it 'fails' (e.g. hits a busy tone, rings out, phone is off, phone cannot connect); this can be before or upon or shortly after the network decides to terminate ringtone or to not offer any ringtone. The network then plays back an IVR recording giving the option of speaking a text (SMS, MMS, email, IM etc) to the person they were trying to call. So the caller always gets through to something useful and which may also be seen as les formal than ordinary voicemail, and hence more likely to be used.
