The line 8 terminates at the cathode 10 of a planar triode amplifier which is biased via a resistor 20. The triode is mounted on a plate 12 secured across the coaxial line; a grid bias determining the amplification is applied to the grid 14 via connecting pin 13 and plate 12. Anode 15 is tuned by a substantially half-wave line 16, from which energy is re-inserted into the cavity 1 by means of inductive loop 18, a D.C. connection to the anode being supplied by pin 19.

Patent GB-2041149-A (GB)
Title: Centrifugal and axial-flow compressors
IPC: F04D27/02
Filed: 1979-01-29
Abstract: A flow stabilizer equalizes the flow of fluid through the passageways of the diffuser of a centrifugal or axial-flow compressor. Slots are formed in the sidewalls of the flow separating vanes in the diffuser. The slots open into cavities within the vanes. The multiplicity of cavities communicate by means of openings through the diffuser wall into a common closed manifold. The rear diffuser wall may have slots opening into the manifold. The fluid interconnection between the multiplicity of passageways in the diffuser and the encircling common manifold increases the operating range of the compressor since pressure surges in one or more passageways are quickly equalized. Air may be bled from the manifold during acceleration of the gas turbine engine containing the compressor, via a bleed valve which is opened by the engine fuel control lever.
