Title: Cooling structure to cool platform for drive blades of gas turbine
Inventor: TERAZAKI MASAO
IPC: F01D5/08
Filed: 1998-02-23
Abstract: A mechanism for cooling the platform for the drive blades of a gas turbine, which uses a simple configuration which will reliably cool the platform, the mechanism being constituted by cooling channels in the interior of the platform which open out from one of the cooling air channels for cooling the turbine blades and which exit the platform through the edge nearest the tail. In a preferred embodiment cooling channels 6a and 6b in platform 2 open out from the entrance to blade cooling channel 5a and travel from the head of the blade along the blade sides 3c and 3d and exit through the edge 3e near the tail of the blade. This structure diverts a portion of the cooling air 4a entering the blade 3 from the cooling channel in base 1 in order to cool platform 2. Alternatively or in addition, at least one of the following types of cooling passages may be provided: (a) cooling air channels 7, which extend from enclosed air space 11 below platform 2 to the upper surface of the platform; (b) convection cooling channels 8 which extend from the leading edge of the platform to the upper surface of the platform at the front or rear side of the blade, and/or (c) air channels 9 which extend on the rear of the turbine blade obliquely from the underside of the platform to the trailing edge of the platform. These various channels or combinations thereof constitute a cooling structure through which air can flow to cool a platform for the drive blades of a gas turbine in an efficient and effective manner.

Patent CA-2234019-A1 (CA)
Title: Miniature mixed gas refrigeration system
Inventor: DOBAK JOHN D III
IPC: F28F13/06
Filed: 1996-10-09
Abstract: A miniature mixed gas refrigeration system is disclosed, having a coaxial catheter (18) with an inner high pressure supply lumen (24) and an outer low pressure return lumen (22). The gas mixture is pressurized by a compressor (12) to a pressure less than 420 psia, for safety reasons. The distal portion (23) of the outer lumen contains a micro-miniature heat exchanger (28) constructed of laminated plates or sheets (42). The plates or sheets (42) establish high pressure (36) and low pressure passageways (40), with high surface area, having a tortuous path for the gas flow to maximize heat exchange. The high pressure outlet (50) of the heat exchanger (28) is connected to a Joule-Thomson expansion element (30) where the high pressure gas is expanded isenthalpically to a lower temperature at least as low as 180K. This low temperature gas cools a heat transfer element (32) mounted in the outer wall of the catheter, to cool an external object. Return gas flows back through the heat exchanger to pre-cool the incoming high pressure gas mixture.

IPC: G06Q30/00
Filed: 1996-12-06
Abstract: A method and system for placing advertisements in a computer network. A server containing a collection of advertisements is placed in electronic communication with the computer network. The advertisements on the server are not tied to any particular page containing information on the network, but rather, are retrieved in response to a query entered by the user (17) and dynamically mixed with the content of the pages returned in response to the query (16). The present invention displays the content pages with focused, targeted advertisements as a part of the page, in accordance with a particular layout. The advertisements can be made to satisfy a set of constraints (19) requested by the advertiser, as well as the constraints of the publisher of the page. The system uses contracts (21) to specify the marketing rules (18) that link ads with specific queries, to permit advertisers to target a specific audience, and to guarantee a certain amount of exposure of the advertisement in prime advertising space. Algorithms are used to check for contract consistency to ensure that all contracts that are accepted can be properly satisfied. The present invention also provides a download delay-time advertising feature.
