1. A method of applying a dry film lubricant to a rotor slot comprising:
removing a rotor blade from the rotor slot; providing a tool and a pad; and
applying the dry film lubricant to the rotor slot using the tool and the pad, the tool including a handle and a supporting member, wherein the pad is removably locatable on the supporting member, and wherein the pad includes a hollow member removably locatable on the supporting member, and wherein the supporting member and the hollow member have matching cross-sectional shapes to prevent relative rotation and the pad has the same cross-sectional shape as the rotor slot.
2. A method as claimed in claim 1 comprising cleaning and degreasing the rotor slot before applying the dry film lubricant.
3. A method as claimed in claim 1 comprising allowing the dry film lubricant to cure before inserting the rotor blade into the rotor slot.
4. A method as claimed in claim 1, comprising curing the dry film lubricant at ambient temperature for at least 1 hour.
5. A method as claimed in claim 1 wherein the rotor slot is a fan rotor slot or a compressor rotor slot.
6. A method as claimed in claim 1 wherein the rotor slot is a turbine engine rotor slot.
7. A method as claimed in claim 1 wherein the rotor slot is substantially dovetail in cross-section.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1-19. (canceled)
20. A method for frequency conversion comprising:
inputting a pilot signal;
generating a local oscillator signal from the pilot signal;
providing a coupler comprising a plurality of rings and a plurality of underpasses connecting ports of the rings for generating differential quadrature signals from the generated local oscillator signal using the electromagnetic properties of coupled rings in said coupler; and
mixing a radio frequency signal and the differential quadrature signals.
21. The method of claim 20, wherein the method is performed entirely on-chip.
22. (canceled)
23. (canceled)
24. The method of claim 20, further comprising at least one of multiplying and dividing the frequency of the pilot signal to be equal to the frequency of the local oscillator signal.
25. The method of claim 20, further comprising a step of buffering the differential quadrature signals to produce buffered differential quadrature signals.
