摘要:
A method for a user to capture, configure, store, link, exchange, and set trading parameters (prices and other exchange values) for data drawn from the user's personal data file combined with other user generated data; including data resulting from the user's interactions with file creation software, data items generated from user interactions with electronic devices and components, and data automatically generated by electronic components and devices owned by a user. In combination, these combined data sources coupled with a personal data file form a digital persona or a “digital doppelganger” that may be traded or sold or retained as private in a data marketplace.

A fully aerobatic oil system for an aircraft gas turbine engine includes two re-circulatory oil systems the pumps for which have inlets 19 and 31a disposed at locations in the engine such that when one inlet is starved of oil, due to the aircraft attitude changing, oil will be supplied to the other one. In a specific embodiment, the breather of the oil system 30 (FIG. 2) is positioned in the engine gearbox and provides the lowest pressure point in the system. The breather is of the type described in UK Pat. No. 1,508,212 which includes a rotating compartment filled with RETIMET (Regd. Trade Mark). The bearing chambers are pressurised with air from the engine and the air/oil mixture in each chamber is vented via a first series of vents 24 to the breather where the air and oil are separated. The breather is used as a pump to pump the separated oil back to the oil tank via a scavenge line 35 which includes a relief valve 38. A bleed line 36 takes some of the oil from line 35 to the main oil supply gallery 23 via a non-return check valve 37. In normal flight pump 20 supplies the gallery 23 from the tank 18 via pump inlet 19, the relief valve 38 being set to a pressure lower than that of relief valve 40 which controls the pump pressure. The check valve 37 thus remains shut. When the inlet 19 is starved of oil because the flight attitude of the aircraft changes, the pressure in gallery 23 drops to the extent that check valve 37 opens and the breather/pump takes over circulating oil from the gearbox and bearings around the second system.

The present invention provides a method for polishing a layer of material, a method for manufacturing a damascene interconnect structure, and a method for manufacturing an integrated circuit. The method for polishing a layer of material, among other steps, includes obtaining a substrate (310) having a layer of material (330) located thereover, and polishing the layer of material (330) using a polishing surface (410). The step of polishing the layer of material may include subjecting the layer of material (330) to a first polishing process using a first endpoint detection method, the first polishing process removing a portion of the layer of material, and subjecting remaining portions (420) of the layer of material (330) to a second polishing process using a second different optical endpoint detection method.

A spinner fishing lure having a frame including first and second diverging arms lying generally in the same plane. A hook is connected to the frame at the distal end of the first arm and lies generally in the plane of the first and second arms. The lure also includes at least two blades and connectors for connecting the blades to the frame generally at the distal end of the second arm. The blades are tethered to the connectors at spaced apart connection points such that the blades may swivel relative to the connectors generally sweeping out overlapping cones as the blades travel through the water so that the blades periodically strike one another to produce a noise attractive to fish. The connectors are configured so that the connection points of the blades and the blades are substantially vertically aligned as the lure is pulled through the water.
摘要:
A gas turbine engine oil system is provided in which the centrifugal separator is arranged to act as a pump for supplying bearing chambers directly, and the scavenging of the bearing chambers is achieved primarily by the pressurization air which flows into the chambers to prevent oil leakage. To avoid the use of pressure regulating valves for controlling the oil flow an oil tank is pressurized and communicates with an auxiliary outlet from the separator, the pressure in which is governed by the quantity of oil flowing around the system. The tank and the bearing chambers are fluidly connected to the centrifugal separator in two separate fluid circuits with each circuit having the separator as an element thereof.

A hydraulic seal and an oil scavenge system are combined, and oil pumping gears and other associated equipment thus obviated. The hydraulic seal 32 comprises an oil reservoir holding centrifuged oil, and an annular fin 22, the periphery of which dips in the oil. The fin 22 has an orifice 33 which receives the oil under pressure derived from the speed of rotation of the oil, and passes it via conduit 34,26 to an oil sump.
摘要:
A device and method for equalizing the pressure between work-space and crankcase in a pressurized engine, such as a Stirling engine. The device consists of a two-way valve connected between the work-space and the crankcase. The valve is connected to the work-space with a passageway including a constriction to provide an mean pressure for monitoring purposes. The valve connects the work-space and crankcase allowing the pressure to equalize when the mean pressure of the work-space exceeds the crankcase pressure by a predetermined amount.

A bearing chamber pressurization system for a ducted fan gas turbine engine uses fan delivery air at relatively low pressure and temperature for bearing chamber pressurization. In order to avoid the possibility of a flow reversal in the pressurization air when the fan speed is reduced, a second higher pressure air supply from the core engine is made available under the control of a valve and pressure sensing device, and which comes into operation when the ratio of the bearing chamber pressure and the supply pressure reaches a pre-determined minimum.

A centrifugal separator for separating suspensions of oil mist in air and especially intended for use with aircraft engines comprises a rotatable chamber filled with a relatively rigid porous material and driven by a hollow shaft.An inlet for the suspension is provided in one end wall of the chamber and separate outlets for oil and air in the form of an apertured chamber outer wall and apertures in the shaft respectively.
