Title: Optical fiber holding structure and method of making same
Inventor: KORDAHI MAURICE
IPC: G02B6/255
Filed: 2001-10-01
Granted: 2010-06-15
Abstract: An optical fiber holding structure is used to restrain high fiber count fibers or to provide splice protection in a cable joint. Layers of fibers are inserted between a compliant splint member and a semi-rigid splint member, which are positioned within an outer gripping tube such as a heat shrink tube.  Optionally, an internal support can be positioned between the layers of fibers. The assembly is heated causing the heat shrink tube to apply a gripping force to the splint members and fibers supported therebetween. Where more than two layers of fibers are being restrained, internal supports can be positioned between each of the fiber layers. One type of internal support includes a rigid beam coated with a compliant material.

Title: Method for determining the angle of a rotor blade pertaining to a wind energy installation
Inventor: WOBBEN ALOYS
IPC: B64C27/02
Filed: 2001-05-05
Granted: 2007-02-20
Abstract: In pitch-regulated wind power installations the angles of the rotor blades can be adjusted synchronously (standard construction) or independently of each other. The construction for adjustment independently of each other is described in patent application DE 197 31 918. That design can also be referred to as on-line individual blade adjustment. Both in the standard construction and also in the arrangement involving on-line individual blade adjustment, it is important that an initial blade angle, for example feathered position or maximum blade angle, can be set with a sufficient degree of accuracy.        The object of the present invention is to avoid the above-discussed disadvantages so that it is possible to more quickly ascertain the correct blade angle and the results are more accurate than hitherto and also measurement from the ground is possible, while the entire measuring equipment should be easily disconnected so that simple transportation of the measuring equipment is also possible.        A method of accurately determining the angle of a rotor blade of a wind power installation, wherein the spacing between the rotor blade and the pylon of the wind power installation is ascertained, the ascertained data are processed in a computer, and the angle (a) between a rotor blade and the spacing measuring device is determined from the stored values.

Title: Apparatus and method for in-situ measurement of residual surface stresses
Inventor: RUUD CLAYTON O
IPC: G01N23/04
Filed: 2001-07-19
Granted: 2011-06-14
Abstract: An apparatus for in situ measurement of residual stresses comprises a compact x-ray tube (104) and a detector. X-rays emitted by the x-ray tube (104) are diffracted from a specimen surface and intercepted by the detector. The intercepted x-rays are converted into light and transferred by a first fiber optic bundle (110) and a second fiber optic bundle (112) to light detection devices (118). Intensities of the received light are digitized by the light detection devices (118) to generate a first ring and a second ring with common centers. The residual stress in the specimen surface is calculated based on a difference between the radii of the first ring and the second ring.

Title: Synchronous, clocked communication system with relative clock and method for configuring such a system
Inventor: FRANKE MICHAEL
IPC: G06F1/14
Filed: 2002-03-11
Granted: 2007-10-23
Abstract: The invention relates to a synchronous, clocked communication system for example a distributed automation system, the stations of which can be arbitrary automation components and are coupled to one another via a data network (1) for the purpose of mutual data exchange. In this arrangement, all possible bus systems such as, e.g. field bus, professional field -bus, Ethernet, industrial Ethernet etc. are conceivable as the data network (1) of the communication system. One station of this communication system is designated as timing generator and ensures the distribution and maintenance of the communication clock used to all stations and by all stations. The timing generator can also introduce a relative clock (9) in the entire communication system at all stations via the same mechanism. This station is thus also the master of the relative clock (9) or, respectively, the applicable relative time (16). All stations of the communication system are, therefore, continuously synchronized to the relative clock (9), which is applicable throughout this system, with the valid relative time (16) and, therefore have the same understanding of time at any time. This distinctly improves or even makes possible, respectively, the implementation of applicative sequences, synchronization of events occurring simultaneously, accuracy in time during the detection of events or, respectively, switching of outputs.
