Abstract: Disclosed is a combined antenna and helicopter rotor blade 101. The antenna comprises one or more electrically non-conductive rotor blades 101, each having an electrical conductor 210, 310 positioned parallel to the major axis of a respective rotor blade 101. A connection means 410, 412, 510, 521, 620, 623 is provided to connect the antenna to apparatus for the reception or transmission of radio waves which is located in the fuselage 102. Also disclosed is a communications system including apparatus for the transmission or reception of radio waves.

Abstract: Disclosed is a combined directional antenna and rotor blade 101 for a helicopter 100. The antenna comprises three or more electrically non-conductive rotor blades 200, each having an electrical conductor 210 positioned parallel to the major axis of a respective rotor blade 200. Two of the electrical conductors 210, having angular positions nearer to a predetermined angular position are connected via a connections means 700 to apparatus for transmission or reception of radio waves. The remaining conductors may either be connected to the body of the helicopter or supplied with a signal out of phase compared to that supplied to the two electrical conductors. Also disclosed is a communications system including apparatus for the transmission or reception of radio waves.

Abstract: An elapsed time recording device includes a counter (130) for incrementally advancing a count value from an initial value towards and beyond a threshold in response to successive clock pulses of a clock signal. Control logic (140) enables the counter (130) to incrementally advance the count value in response to a first input (pin 3) and a second input (pin 1) being at or near a first voltage level, and holds the count value in response to the first input (pin 3) being at or near a second voltage level and the second input (pin 1) being at or near the first voltage level. Setting logic (210) sets the count value to a value beyond the threshold in response to the first input (pin 3) and the second input (pin 1) being at or near the second voltage level when the count value is between the initial value and the threshold. Because the device consists essentially of electronic circuit elements, it can be implemented in the form of an application specific integrated circuit package suitable for high volume manufacture at relatively low cost. The device is therefore favourable for use in mass produced electrical appliances. Because the count value is immediately advanced beyond the threshold in response to removal of the second input voltage, advance of the count value towards the threshold cannot be prevented or delayed by tampering with pin connections of the device.

Abstract: Linearity correction apparatus for a raster scanned cathode ray tube display device is presented. The apparatus comprises fisrt means (16) for generating a correction signal to correct an asymmetric non linearity in a sawtooth electron beam line deflection current. The line deflection current is generated by a line timebase circuit for energising electromagnetic electron beam deflection coils of the cathode ray tube. The apparatus further comprises second means (70,90,91) cooperative with the first means (16) and responsive to a change in line timebase frequency for compensating a variation in the correction signal generated by the first means (16) in response to said change in line timebase frequency.
