Title: Improvements in or relating to ice detecting apparatus for air compressors
IPC: F02C7/047
Filed: 1947-03-25
Abstract: 622,554. Gas turbine plant; axial-flow compressors. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. March 25, 1947, No. 8101. Convention date, Sept. 24, 1945. [Classes 110(i) and 110(iii)] To de-ice an air compressor having a suction passage in which are arranged a plurality of inlet guide vanes, at least one of the guide vanes is made hollow to form a chamber and means are provided to suck air through said chamber from the suction passage 'through orifices so that when ice forms on the inlet orifice the pressure in the chamber falls and causes means for removing the ice to be operated. One or more of the inlet guide vanes 16 of a compressor forming part of a gas turbine jet propulsion plant are made hollow and provided with air inlet and outlet orifices 42, 47. Air is caused to flow through the vane by a vacuum pump 44 and the pressure in the chamber is used to operate, through a diaphragm 52, a switch 51. When ice forms on the inlet orifices 42, the pressure inside the vane falls and 'the diaphragm 52 operates switch 51 to close the electrical circuit. A signal light 61 is lit and a solenoid 62 energized. The solenoid opens a valve 63 in a pipe 66 conducting hot air from the compressor discharge to an annular header surrounding and discharging into the compressor inlet. This hot air mixes with the air entering the compressor, raises its temperature and causes the ice to melt. The pressure inside the, vane 'then rises and the spring 56 opens the switch 51. The solenoid is then de-energized and the spring 65 closes the valve 63 and shuts off' the supply of hot air. Specifications 590,799 and 592,505, [Group XII], are referred to.

Title: Improvements in electric remote control apparatus
IPC: G05B11/01
Filed: 1962-02-12
Abstract: 943,205. Controlled non-linear inductors. W. BROOKE, and H. HOWE. Feb. 12, 1960, No. 8139/62. Divided out of 943,204. Addition to 864,714. Heading H3B. A main transductor C as described in Specifiction 864,714 controls the application of current from an A.C. supply L1, N, Fig. 1, to a load M1, and the load circuit Lla, Na is shunted by an auxiliary transductor GR, one of the two transductors being selectively excited over a relay CR so that when the main transductor C is saturated the auxiliary transductor GR is unsaturated and vice versa. This arrangement ensures that the load circuit has a substantially zero potential when the main transductor is unsaturated, the saturated auxiliary transductor providing a low impedance path for the main transductor magnetizing current. Normally the auxiliary transductor is saturated by current in control windings GR1e, GR2e derived from the supply by way of a transformer E and rectifier F. When a start button K is depressed, an operating circuit is completed for relay CR which locks up and transfers the control excitation from the auxiliary to the main transductor at terminals 6, 9. Current is now applied to the load until such time as the excitation is interrupted, either by a stop button J or the opening of contacts 43, 44 of an overload relay Z. Relay CR then falls back and re-applies saturating excitation to the auxiliary transductor. In an application to a three-phase system, Fig. 2, in which a delta-connected load has separately switched phases Mxa, Mxb, Mxc, a main transductor C, Ca, Cb is provided in each line. The remaining circuits are as previously described, except for their adaptation to threephase working. In an alternative embodiment, Fig. 3, control excitation is derived from both the supply and the load sides of the main transductors C, Ca, Cb as described in Specification 943,203, the load side excitation being obtained either from a transformer G or from transformer windings GR1s, GR2s, GR3s on the auxiliary transductors GB1, GR2, GR3. Specification 900,196 also is referred to.
