20150219115 | Blade for Axial Compressor Rotor - A blade for a compressor rotor comprises a blade root at a first end of the blade extending from a rotor body of the compressor, and a blade tip at a second end of the blade. The first end and the second end are disposed on a span of the blade. The blade root and the blade tip define a face of the blade between them. The blade tip comprises a first extremity and a second extremity. The blade tip is disposed such that a first segment of the blade tip defines a positive dihedral angle with the face of the blade. The first segment extends from a first point in the blade tip to the first extremity of the blade tip. A second segment of the blade tip defines a negative dihedral angle with the face of the blade. The second segment extends from a second point in the blade tip to the second extremity of the blade tip. | 08-06-2015 |

20130185131 | SYSTEM AND METHOD FOR INTEGRATING SOCIAL AND LOYALTY PLATFORMS - A method may to authorize a loyalty integration service with a social platform may include transmitting an authorization screen to a user terminal. The authorization screen may include a request to grant a loyalty integration service (LIS) user application access to an identifier of a user on a social platform. The method may further comprise receiving authorization from the user indicating the LIS user application can access the identifier of the user. Then, based on receiving the authorization, the identification of the user on the social platform may be linked with a member identifier associated with the user on a loyalty program. Further, on the user terminal, a dashboard to the user may be presented within the LIS user application. The dashboard may include offers customized for the user based on the user's social data in the social network and loyalty data in the loyalty program. | 07-18-2013 |

20090056908 | Regenerative heat exchanger - The invention relates to a regenerative heat exchanger for the heat exchange of gaseous media with a substantially cylindrical heat storage body. The invention further relates to a radial seal for use in a regenerative heat exchanger and a method for separating gaseous media in a regenerative heat exchanger. The heat storage body of the regenerative heat exchanger comprises a plurality of radially extending sector walls which subdivide the heat storage body into sectors. At least two heat storage chambers which are arranged behind one another in the radial direction are provided within a sector, which heat storage chambers are arranged for the through-flow of gaseous media. Radial seals are further arranged on the face side of the heat storage body for separating the gas streams, which seals form cover surfaces for the heat storage chambers and cover the heat storage chambers in an alternating manner during the operation of the regenerative heat exchanger, with the radial seals and the heat storage body being twistable relative to each other. In order to prevent the occurrence of oscillations which are caused by the pressure differences prevailing in the heat storage body between the individual gas areas, the radial seals are arranged in such a way that of the heat storage chambers of a sector which are arranged behind one another they cover at most partly the opening of at least one heat storage chamber in any rotational position. | 03-05-2009 |
20110048670 | METHOD FOR THE TEMPERATURE-DEPENDENT SETTING OF A SEALING GAP IN A REGENERATIVE HEAT EXCHANGE, AND THE RESPECTIVE ACTUATING APPARATUS - The invention relates to a method for temperature-dependent setting of a sealing gap between an adjustable seal and a revolving rotor of a regenerative heat exchanger by means of at least one actuating apparatus which comprises at least one rod body which is thermally influenced in an alternating manner and whose temperature-dependent change in axial length is converted into an actuating movement for the seal. It is provided in accordance with the invention that this rod bod is arranged at least in sections in a chamber and a control medium flows through or about this chamber at least in part, which medium acts in a direct or indirect manner in a thermally alternating fashion on said rod body, with the temperature level of the control medium corresponding to a temperature level of a gas volume flow flowing through the rotor, so that a change in axial length of this rod body is produced depending on a temperature change of this gas volume flow and a respective actuating movement for the seal is brought about. | 03-03-2011 |
