摘要:
A hot-gas stream (40) flows along the surface of a segment arrangement for shroud bands, in particular in a gas turbine. The segment arrangement comprises segments (20, 20′) arranged next to one another and in each case separated from one another by a gap (12). The hot-gas stream (40), in at least one section (70) of the gap (12), has a velocity component perpendicular to the direction of the gap from a first segment (20) to a second segment (20′). In this case, in said section (70), along that edge (26) of the first segment (20) which faces the gap (12), at least one film-cooling bore (52) connects a cooling-air chamber (50), allocated to the first segment, to the surface (22) subjected to the hot-gas stream (40), and/or, in said section (70), along that edge (26′) of the second segment (20′) which faces the gap (12), at least one edge-cooling bore (56) connects a cooling-air chamber (50′), allocated to the second segment, to the inside (28′) of the gap (12).

Platform cooling having a guide-blade platform (30; 60) which is subjected to a hot-gas stream (20) and is separated by a gap (36; 66) from a combustion-chamber segment (40; 70) arranged upstream, one or more segment cooling bores (42; 72) being made in the combustion-chamber segment (40; 70), which segment cooling bores (42; 72) connect a cooling-air chamber (44; 74) to the gap (36; 66). The guide-blade platform (30; 60) has a surface (34; 64) on the downstream side in the region of the gap (36; 66), the axes of the one or more segment cooling bores (42; 72) running roughly tangentially to said surface (34; 64).

The invention relates to an impact flow for wall sections including a plurality of impact openings which are arranged on a plane in a flat or curved support. The support is fitted it a distance from the wall section, and the impact surface of the wall section that is to be cooled is configured as a bulged relief. The bulge elements are arranged around the impact surface of the impact beam. The surfaces of the bulge elements facing the impact beam include two curves which blend into one another.
摘要:
A tile tray (1) including a generally planar base (2) and two or more retaining members (5) adapted to locate and retain a tile (7) to the base. The tile tray (1) further includes a coupling means for connecting two or more of the tile trays in a substantially aligned configuration.

The invention facilitates the computation of expected approval rates based on historic transaction data relating to transaction classes, approved transactions and declined transactions. The invention provides a system and method by which a program administrator for a company may model varying client-imposed limit scenarios in order to determine one or more optimal monthly and/or transactional spending limits. Further, the present invention provides a means for setting varying monthly and/or transaction spending limits for purchases from any number of industries. Providing card members with information regarding optimal spending limits reduces the occurrences of declined credit transactions. A program administrator may also utilize the present invention to provide any number of limit scenarios in order to persuade a card member to increase their client-imposed credit limit to an optimal level thereby reducing the card member's inconvenience caused by declined purchase transactions while recapturing lost revenues by the card issuer.
摘要:
The invention facilitates the compilation of client-imposed charge or credit limit reports based on declined purchase and/or payment transactions. The invention provides a system and method by which an account manager for a financial institution and/or a client program administrator company may perform analysis of spending patterns for cardmembers in order to determine an optimal client-imposed credit limit in order to reduce the occurrences of declined charge or credit transactions. An account manager for a financial institution and/or a client program administrator may use the limits report to persuade a cardmember to increase the client-imposed credit limit to a recommended level, thereby reducing the cardmember's inconvenience cased by declined purchase transactions while recapturing lost revenues by the card issuer also resulting from declined purchase transactions.
摘要:
A method for predicting the elution time of a peptide in chromatographic and electrophoretic separations by first providing a data set of known elution times of known peptides, then creating a plurality of vectors, each vector having a plurality of dimensions, and each dimension representing positional information about at least a portion of the amino acids present in the known peptides. A hypothetical vector is then created by assigning dimensional values for at least one hypothetical peptide, and a predicted elution time for the hypothetical vector is created by performing at least one multivariate regression fitting the hypothetical peptide to the plurality of vectors. Preferably, the multivariate regression is accomplished by the use of an artificial neural network and the elution times are first normalized using linear regression.

Communications device identification methods, communications methods, wireless communications readers, wireless communications systems, and articles of manufacture are described. In one aspect, a communications device identification method includes providing identification information regarding a group of wireless identification devices within a wireless communications range of a reader, using the provided identification information, selecting one of a plurality of different search procedures for identifying unidentified ones of the wireless identification devices within the wireless communications range, and identifying at least some of the unidentified ones of the wireless identification devices using the selected one of the search procedures.
摘要:
A utility knife includes a body having a groove adapted to receive a blade. The groove has a plurality of tabs defined on at least a first side. The utility knife also includes a slide assembly device positioned in the body for sliding movement with respect to the body. The slide assembly device includes a housing with a first engaging member having a first protrusion and a second engaging member having a second protrusion releasably engaged with the tabs. The slide assembly device also includes a rocker attached to the housing that is operatively connected to at least one of the engaging members. The rocker is operable for disengaging the first protrusion or second protrusion with respect to the tabs. Disengaging one of the first and second protrusions by the rocker allows sliding movement of the slide assembly device with respect to the body.
