Abstract: A system (10) for lancing sludge deposits (12) from within a bundle (14) of vertically extending steam generator tubes (16) of a PWR steam generator secondary side assembly (18) has a flexible lance (28) mounted in a lance guide/housing transporter (30). The transporter (30) is movable along blowdown (20) to position end (32) of the flexible lance opposite one of the inter-tube lanes (26) so that the flexible lance (28) may be inserted along the selected inter-tube lane (26). A rigid lance guide (34) on the transporter (30) has a curved end (36) configured to turn the flexible lance (28) at a chosen angle, such as 90 DEG , so that the flexible lance (28) will be fed into the selected inter-tube lane (26). The transporter has a drive (37) for advancing the flexible lance (28) through end (36) of the lance guide (34) and into the inter-tube lane (26). The flexible lance (28) includes a flexible plastic extrusion (38) with a plurality of hollow, flexible metal conduits (40) within the plastic extrusion (38) to extend lengthwise along the lance (28). The nozzle block (44) has nozzles b 48, 50 and 52 so that all portions of the sludge deposits (12) adjacent to the selected inter-tube lane (26) can be reached by the flexible lance (28).

Abstract: A method for creating a 3-D television effect is disclosed in which a scene is recorded with a relative lateral movement between the scene and the recording mechanism (2). The recording is played back and viewed through a pair of viewer glasses (46) in which one of the lenses (18) is darker and has a spectral transmission characterized by a reduced transmissivity at at least one, and preferably all three, of the television's peak radiant energy wavebands. The lighter lens (20), on the other hand, has a spectral transmission characterized by a reduced transmissivity at wavelengths removed from the television energy peaks. The result is a substantially greater effective optical density differential between the two lenses when viewing television than in normal ambient light. This produces a very noticeable 3-D effect for television scenes with the proper movement, while avoiding the prior "dead eye" effect associated with too great a density differential in ordinary light. Further enhancement is achieved by providing the darker lens (18) with a higher transmissivity in the blue and red regions than in the yellow or green regions.

Abstract: A method, a device, and a corresponding system for controlling a discrete production process produce or process in a number of production steps. Each step uses a machine, so that different intermediate products are produced. Buffer times are defined and taken into account during which one machine is able to continue to operate for the duration of the failure of one of the machines of a preceding production step by processing a stock of intermediate products corresponding to the associated buffer time and stored in a buffer during the production. In this case, production data are acquired continuously for each machine and, with access to these production data, statistically averaged repair times MTTRi (Mean Time to Repair) are calculated cyclically by using a MTTR calculator. Based on these times MTTRi, buffer times are calculated by using a TP calculator and are fed to a device for controlling the production process as desired values for buffer times.

Abstract: The curtain coating assembly (10), to coat the surface of a moving web substrate (U) with a paste or liquid coating (18) and especially a pigment suspension, has a jet unit (14) at the applicator (12) to deliver a coating curtain (18). At least one guide (22) is in the falling path of the coating curtain, which directs the coating over the whole curtain width over at least a part of its falling path. The web curtain coating assembly has a guide in the path of the falling coating curtain, which divides it into a path section (24) between the feed and the guide, and a second path section (26) between the guide and the moving substrate. The guide can be directly at the delivery jet. The variable length of the curtain coating which covers the guide is measured in the direction of its movement. The guide forms an included angle ( alpha ) of 5-30 degrees with the direction of the curtain coating free fall line. The surface (22a) of the guide, covered by the coating medium, forms an included angle ( beta ) with the end surface (22b) of the guide of 20-60 degrees . The guide can be a guide scraper against the substrate. The guide is pitched at an angle of 20-80 degrees in the required flow direction, and preferably 45-80 degrees . The end of the guide surface towards the moving substrate can be extended at an angle of 30-50 degrees . The guide can also cover the whole flow stretch for the coating medium, between the delivery jet and the moving substrate. The surface of the guide, towards the coating medium, has a hydrophobic character, or has a hydrophobic cladding of a treated glass fiber film. At least the end surface of the guide is free of hydrophobic cladding. The coating curtain flows over the upper surface of the guide, or along its under surface. At least one electrode can be at the guide, on the side away from the flowing coating. A suction box is at the moving substrate, in front of the contact line where the coating curtain strikes it, together with a scraper at the entry and/or exit side, with a scraping edge lying on the moving substrate. The scraper at the exit side can be formed by the coating guide. The coating curtain flows over the guide surface, in a length (l) of 1-200 mm and preferably 1-50 mm. The travel speed of the substrate is 1000-3000 m/min. for a paper web and 200-1000 m/min. for a cardboard web. The coating is applied in ready doses to the substrate surface. The delivery jet has a coating delivery rate of 2-200 l/min. per meter of the web width. The length (H) of the coating curtain is 5-400 mm and preferably 40-200 mm. The guide is of metal or plastics e.g. a plastics with reinforcement carbon or glass fibers. The guide has a thickness (D) of 0.2-1.0 mm. The guide is positioned at the applicator, at an angle to the moving substrate of 70 degrees , in either direction. The guide can have a convex or concave curvature, with a curved surface at a tangent to the free fall of the coating curtain, in either direction, at an angle of up to 70 degrees .
