Abstract: A search system for information retrieval comprises a data structure in the form of a non-evenly spaced sparse suffix tree for storing suffixes of words and/or symbols, or sequences thereof, in a text T, a metric M comprising combining edit distance metrics for an approximate degree of matching respectively between words and/or symbols, or between sequences thereof, in the text T and a query Q, the latter distance metric including weighting cost functions for edit operations which transform a sequence S of the text into a sequence P of the query Q, and search algorithms for determining the degree of matching respectively between words and/or symbols, or between sequences thereof, in respectively the text T and the query Q, such that information R is retrieved with a specified degree of matching with the query Q.      Optionally the search system also comprises algorithms for determining exact matching such that information R may be retrieved with an exact degree of matching with the query Q. A method in the search system comprises generating the data structure as a word-spaced sparse suffix tree, storing sequence information of the words in the text T in the generated suffix tree, generating a combined edit distant metric for words or sequences thereof in the text T and a query word q or sequences thereof in the query Q and including word-weighting cost functions for the sequence-transforming edit operations, and determining the degree of matching between retrieved information R and a query Q. - Use in an approximate search engine.

Granted: 2006-07-04
Abstract: A lighting box has a housing with an open front and open rear and a bar such as a standard schedule 40 pipe or 1 1/2" or 1 5/8" pipe extending horizontally across the housing. Multiple lights are mounted on the bar and positioned to send light out the front of the box. The box also has a diffusion element (frame) disposed proximate its front end, and even may have multiple elements including having one element at an angle. The element or elements receive the light from the lighting instruments and diffuse it to provide a soft projected light from the box. In accordance with one aspect of the invention, this light may be used to provide diffused light as part of the key lighting for a stage or set, and may provide such soft projected lighting from a front (downstage) of the stage or set. The box may also have a soft shell, may hang overhead, on a stand or by a rotatable yoke, and may have lights fixed therein. The box may also have a rear cover.

Abstract: When running pipes or lines through a wall of a structure a hole is drilled in the wall during fabrication of the structure and then the line or pipe is run through the hole and to the outside of the building. Hose bibs or sill cocks typically include a faucet-like member and a base with notches located on opposite sides of the base. The hose bib attaches to the pipe and the hose bib is secured to the outside wall of the building usually by screws.     A problem which frequently occurs with this practice, however, is that the pre-formed hole is too large so that the hose bib or sill cock cannot be secured to the wall. That is; there isn't anything to which the screws may attach. The present invention seeks to correct this problem by providing a flat, essentially diamond-shaped plate with a plurality of holes located therein. A hole larger than the other holes is located in the center of the plate. A hose bib having a base with notches located on opposite sides of the base is mounted to the plate so as to align the hose bib with the central hole. Each of the notches of the base is aligned with a hole located on either side of the central hole. Screws are then inserted into the notches and through their respective holes, thereby securing the hose bib to the plate.      The plate is then secured to the wall.

Abstract: The invention relates to a method of mixing pulp components in the manufacture of paper, in which method the pulp components to be mixed are led to a mixing point (S) along tubes arranged inside each other. The pulp component flows are mixed by generating turbulence in them by means of the end of an inner tube (2; 2a to 2c), the cross-section of which end is wave-like. This turbulence is guided and its effect is intensified by means of form parts (4a to 4c) in connection with the mixing point, which form parts are arranged on the inner surface of the outer tube. Further, the invention relates to an arrangement implementing the mixing of pulp components in accordance with the method.

Abstract: The invention relates to a method and an apparatus for measuring a coating from paper or board. The measurement is carried out by one detector at different times or by two detectors (208, 210) simultaneously. IR radiation directed at the coating (204) and radiation reflecting from the coating (204) are chopped synchronously in blocks (292, 206). A wavelength band sensitive and insensitive to the absorption are bandpass filtered and measured in both the MIR and NIR region. The absorption strength is measured in a digital signal processing block (220) by comparing the radiation sensitive to absorption to the radiation insensitive to absorption, and the amount of each coating component is determined in the digital signal processing block (220) on the basis of the absorption strength.

Abstract: The present invention relates to an improved method for the manufacture of aircraft engine cylinder barrels to prevent their premature failure due to hairline cracks or specks thought to be caused by caustic stress corrosion cracking during black oxide treatment. Machined aircraft cylinder barrels immersed into a black oxide chemical bath composed of a solution containing about 60% sodium hydroxide, about 0% sodium nitrate, and about 40% sodium nitrite most effectively prevents specks and hairline cracks. Since residual stresses from machining also contribute to the probability that specks or hairline cracks will occur during black oxide treatment, the maximum selecte d number of cylinder barrels essentially free of detectible specks or hairline cracks determines the maximum number of cylinder barrels to be machined on a given set of tool bits.

Granted: 2008-10-21
Abstract: Supplemental walk along control for walkie/rider pallet trucks (100) is provided by supplemental job switches (128, 130, 128A, 130A) and coast release switches (111) provided adjacent to the base of load carrying forks (106). The supplemental jog switches are enabled during coasting operation so that operators can advance to the base of the forks to accelerate the trucks between closely spaced picks located along substantially straight portions of pick routes. For application of the trucks' brakes (117), the operators activate the coast release switches to release the coast mode and enable deadman brake mechanisms (133) to brake the trucks. A steering direction detector (127) is provided to determine the direction of the steered wheel so that if the steered wheel is not directed substantially straight ahead, then operation of the truck from the supplemental jog switches is disabled.
