Abstract: A steam-cooling gas turbine in which cooling steam is fed from a center portion of a rotating shaft and recovered through passages disposed at the outer side of the center portion with steam leaking through a seal portion from a feeding steam being effectively recovered. Feed steam (30) serving as coolant is supplied to a cavity (27) from a inner cylinder (10) and hence fed to moving blades (11, 12) through recesses (40) formed in a coupling portion (26) interposed between a final-stage disk (24) and a turbine shaft (1), steam feeding pipes (15) and steam feeding passages (11a, 12a). After cooling of the moving blades, steam (31) is recovered through steam recovering passages (11b, 12b), steam recovering pipes (16), radial steam-recovering passages (17), axial steam-recovering passages (18) and outlet openings (5a). In a portion of the turbine shaft (1) located adjacent to the coupling portion (26), temperature becomes higher when compared with the other portion. Thus, the coupling portion (26) is forced to hermetically close under thermal stress, whereby leakage of the feed steam (30) is prevented. Steam leaking through a seal portion constituted by stationary and rotatable seal fin assemblies (4a, 4b) can be effectively recovered. The inner cylinder (10) can move in the axial direction through cooperation of piston rings (43) and a centering piece (6) adapted for absorbing thermal stress induced in the inner cylinder (10). Upstream tip end portions of steam feeding pipes (15) and steam recovering pipes (16) are secured onto a side surface of the first-stage disk (21) through sleeves removably fitted thereto.

Granted: 2003-05-20
Abstract: In methods and apparatus for controlling allocation of traffic channels in a telecommunications network having macrocells and microcells within the macrocells, a macrocell traffic channel is allocated in response to a request for a microcell traffic channel only when no suitable microcell traffic channel is available, a suitable macrocell traffic channel is available, and the requested microcell traffic channel is requested to implement a microcell to microcell handoff. Allocation of the macrocell traffic channel may further be conditional on a grade of service in the macrocell being deemed acceptable.  The grade of service may be deemed acceptable when number of macrocell traffic channels assigned to each microcell is less than a predetermined maximum number of allowable macrocell traffic channels that can be assigned to each microcell (cutoff value) or when more than a threshold number of macrocell channels are available in the macrocell.

Title: Device for removing a liquid from capillaries
Inventor: PETERS RALPH-PETER
IPC: B01J19/00
Filed: 1999-12-21
Granted: 2008-02-12
Abstract: Liquid components are separated from a liquid using separation devices, such as filters and membranes, in which capillary forces which retain the liquid component to be separated off in the separation device are effective. If the amount of liquid is only small, it can be very difficult to remove the liquid component to be separated off from the separation device in free and unchanged form. This process step is simplified or facilitated by a wedge-shaped cut-out at the exit end of the capillary or in a columnar body which is in contact with the exit end of the capillary. The radius of curvature of the wedge edge is smaller than the radius of the capillary. The base side of the wedge-shaped cut-out is adjacent to a collecting chamber, in which the separated-off liquid component is collected, and in which the capillary forces are smaller than in the capillary. If interfering capillary forces are still effective in. the collecting chamber, a further wedge-shaped cut-out can be provided at the exit end of the collecting chamber. The device makes it possible to separate off liquid components in the microlitre range.

Title: Enhanced fatigue strength orthopaedic implant with porous coating and method of making same
Inventor: SHETTY H RAVINDRANATH
IPC: A61F2/36
Filed: 2000-03-03
Granted: 2010-09-07
Abstract: A method for producing an orthopaedic implant having enhanced fatigue strength. A forged implant substrate having an elongated stem is incorporated with a melting point lowering substance. Then, metal particles are sintered to the substrate, forming a porous layer on the substrate which enhances bone ingrowth or the mechanical interlock with bone cement. Advantageously, the sintering occurs at a lower temperature than if the substance were not incorporated into the substrate, which in turn results in an enhanced fatigue strength of the inventive implant. The fatigue strength of a forged or cast implant can also be improved by nitrogen diffusion hardening and/or thermally processing the implant after the porous coating is adhered by sintering. Further, the fatigue strength can be further improved by combining incorporating the melting point lowering substance with nitrogen diffusion hardening and/or aging treatment subsequent to sintering.

Abstract: Discloses a multi-flavour hot beverage dispenser apparatus adapted to dispense a selected flavour hot drink. The dispenser apparatus has hopper to hold a base powder. The hopper includes a hopper dispenser outlet including a motor driven auger to dispense the base powder from the hopper and a hot water boiler and hot water dispense valve. The hot water boiler has controlled heating means to heat the water to the desired temperature. A plurality of liquid flavour dispensers is provided with one or more dispensers selectively activatable to dispense a flavour syrup to flavour the dispensed hot drink to the desired flavour. The liquid flavouring supply is remote from the beverage dispenser allowing a compact sized dispenser which requires minimal counter space that does not increase with increasing flavour selection offerings. A mixer mixes the hot drink constituents to produce the selected flavour of hot drink indicated by a user by depressing a dispense key corresponding to the desired size and flavour of drink to be dispensed. A portion controlled or push and hold dispense cycle is described. In addition, drink constituent supply sensors are disclosed which operate to disable hot drink dispensing when a supply is low.
