Abstract: A stator blade carrier for a gas turbine is provided. The stator blade carrier includes a plurality of axial segments. At least one axial segment is designed as a tubular lattice structure. This allows a simpler design technically and a more flexible adaptation to the temperature profile present on the stator blade carrier to maintain operational safety.

Abstract: An axial compressor is provided. The compressor has an annular flow channel, in which adjustable blades of a blade ring that extend through the flow channel are rotatably mounted. Each blade has a lug on the rotor-side of the vane for mounting an inner ring. In order to provide a wear-free, self-centering inner ring, the ring is designed as a split ring with two opposing ends and a spring element for spreading the split ring.

Abstract: An axial turbo-compressor for a gas turbine having a stator vane assembly that is formed by stator vanes having vane tips exposed on the hub side and a stationary shaft cover on the hub side and delimits the flow channel of the axial compressor is provided. A radial gap is designed between the shaft cover and the van tips that is minimally sized such that the axial turbo-compressor may still be assembled, and there is a plurality of recesses in the shaft cover, wherein one of the recesses is allocated to each vane tip that is arranged directly neighboring the vane tip allocated thereto and is sized such that during operation of the axial turbo compressor every vane tip may be plunged into the recess allocated thereto without one of the vane tips significantly contacting the shaft cover.

Abstract: An axial compressor for a gas turbine having passive radial gap control is provided. The axial compressor includes a guide vane support on which guide vanes are fastened so as to be arranged in a ring, wherein the vane tips of the guide vanes lie opposite a wall section. Thermal insulation is attached to the wall section in the section lying opposite the vane tips in order to equalize the expansion behavior of the guide vane support and the wall section, which by themselves react thermally in different manners, wherein the terminal insulation is matched in the heat input delay effect thereof to the wall section and to the guide vane support in such a way that the thermal expansion behavior of the guide vane support and the wall section is at least equalized over time during transient operation of the axial compressor.

Abstract: The invention relates to a device for support of an adjusting ring which encompasses at a distance a basically circular blade carrier, which adjusting ring is rotatable in the circumferential direction around a center axis which is identical with the blade carrier, in order to adjust radially extending blades of a ring of a turbo-engine, wherein a plurality of levers are provided between the blade carrier and the adjusting ring, which levers are distributed over the circumference, extend tangentially in each case, and which on their free ends have a rotatable roller in each case, which are rollable in the circumferential direction on the adjusting ring or on the blade carrier. According to the invention, the lever is tightly clamped on one side to disclose a wear-free and reliable device for support of an adjusting ring which encompasses at a distance a circular blade carrier.

Abstract: The invention refers to a device for determining the angular position of a compressor stator blade, which is rotatable around its longitudinal axis and arranged in a compressor, with which is associated a measuring surface which rotates synchronously with it. For a reliable, simple and approximately error-free recording of the angular positions, the angular position of the compressor stator blade can be determined via the device in an automated manner. For this purpose, it has at least one mounting unit provided for aligned fastening of the device on the compressor, and at least one measuring and evaluating unit which comprises at least two distance sensors which each record a distance to the measuring surface which is rotatable from the reference position, as a result the angular position of the measuring surface, relative to the reference position depends upon the two recorded distances, is determined by the measuring and evaluating unit.

Abstract: A method for conducting “one to one” commercial negotiations through an electronic medium such as the Internet. The negotiation process consists of sending persuasive texts to the user by the system, including discounts given by the system and responses to the price offers of the user. The system offers the product for a specific price, a price that may be optionally decreased as negotiation continues. The system frequently asks how much the user is willing to pay for the product. Based on the user's input, the system may accept the offer or, after one or more unacceptably low inputs from the user, may alternatively end the process of negotiation. Preferably, the system negotiates on many more parameters than simply the price itself. For example, the system may offer the user several presents or benefits in order to secure the sale. Commercial considerations are preferably included during this process.

Abstract: A method for enabling users over a network or over the WWW to interact with an interactive sales representative system for providing sales guidance. The system offers the user products, services, or ideas (the "products") according to parameters collected from the user. The system guides the customer to retrieve the desired products. If the system does not have a product matched to the customer requirements, preferably it will operate a mechanism for suggesting alternatives which are the closest to the customer requirements. The system will execute various sales tools and techniques to help and assist the customer and to convince the customer to purchase a product. By guiding the customer to the target product, the system will shorten the search cycle for the customer as well as find better matched products. The system will provide market advisory, suggest, recommend, discuss (in written form and optionally voice form), comment, advise the customer regarding the products.

Abstract: A method for transmitting credit card numbers in a secure manner through an electronic medium such as the Internet. Credit card numbers typically consist of a string of 10-20 digits, with the exact number of digits depending upon the provider of the credit card. The security is provided by transmitting the credit card number in a plurality of different transmissions, each transmission containing at least one digit of the credit card number, but fewer than all of the digits of the credit card number. Preferably, the user selects the number of digits from the credit card number to send with each transmission. Thus, the entire credit card number can only be determined by receiving all of the transmissions from the user, thereby significantly increasing the difficulty of intercepting the credit card number.
