Inventor: BARRATT CRAIG H
IPC: H04J99/00
Filed: 1997-07-21
Abstract: The wireless system at a base station for receiving uplink signals transmitted from a number of remote terminals using a common conventional uplink channel has a receiver system with a number of antenna elements and receivers for producing measurements of combinations of the uplink signals. A receive spatial processing device determines and stores receive spatial signatures for the remote terminals using the measurements. A spatial demultiplexer uses the receive spatial signatures and the measurement to produce separated uplink signals. The uplink signals from the remote terminals can be received independently while simultaneously communicating on the common uplink channel.

Title: Panoramic ship-borne sonar system - utilises single spectral analyser to process data from several receiver channels
IPC: G01S7/62
Filed: 1958-08-28
Granted: 1977-06-24
Abstract: The panoramic sonar system is for use on board a ship, it detects fixed or moving obstacles which are generally submerged, such as submarines. This is performed using a receiver in which several input channels are applied to a single spectral analyser. Sonar signals received on several channels (1) are applied to frequency changers (2) utilising a local oscillator (3). These signals are filtered (4) prior to sampling (7) and mixing (11). The mixer output is applied alternately to two memory circuits (16a, 16b) via a write switch (17). A read switch (18) applies these stored signals to an analyser (91) for display on a screen (93). A selector (94) allows the largest amplitude signals to be selected from a number of channels, in order to modulate the spot on the display tube.

Title: Improvements in or relating to Levelling Circuits
Inventor: CHANOT GRIFFITH JOHN RAYMOND
IPC: H04N5/18
Filed: 1966-01-14
Abstract: 1,176,462. Picture signal circuits; semiconductor circuits. ELECTRIC & MUSICAL INDUSTRIES Ltd. 16 Jan., 1967 [14 Jan., 1966], No. 1796/66. Headings H4F and H3T] A television signal is coupled from an input terminal 1 to an output terminal 3 by way of a main high-pass filter channel comprising a capacitor 2 and a resistor 7, a unity gain feedback path being provided from the output terminal 3 to the lower end of resistor 7 through a circuit comprising unity gain amplifiers 4 and 6 and a clamp circuit 9 which operates in response to pulses occurring during the line back-porch intervals to connect the lower end of resistor 8 to a reference potential 11. The time-constant of the RC combination 2, 7 is substantially larger than the time-constant of the RC combination 5, 8; ten times in the particular embodiment described. At frequencies at and above line frequency the feedback path causes resistor 7 to behave effectively as a very high value resistor, whereby the signal is transmitted with negligible loss or distortion. At frequencies below line frequency the clamp 9 causes the signal at the lower end of resistor 7 to differ from that at the top if there is any error in the signal lever. The effective time-constant of capacitor 2 and resistor 7 is thereby reduced, causing attenuation of the signal and a reduction in the error. The circuit is of use with a colour television signal since it permits signal level control without loss of the colour synchronizing " burst " which occurs during the back porch interval. With monochrome signals, where there is no back porch signal to be disturbed by the clamp operation, an output signal of improved signalto-noise ratio may be taken.

A rotary wing aircraft comprises a fuselage, a shaft-driven single rotor mounted over the fuselage, a tail mounted propeller 11 (Fig. 3, not shown), a shroud 10 encircling the propeller, and defining an air duct in which the propeller rotates, the axis of the shroud and the rotational axis of the propeller being co-incident and extending longitudinally of the aircraft, and a rudder 24 pivotable about a vertical axis for deflecting the propeller slipstream. Elevators 19 are provided at the top and bottom of the shroud for pitch control, and the propeller is mounted in the throat of the duct, which is of aerofoil section. In forward flight the aircraft may be partly supported by fixed wings 7 and the rotor may autorotate. Control.-In forward flight, yaw control is effected by the rudder 24, whereas in hovering flight the rudder is fixed at about 70 degrees to the fore-and-aft position and the propeller pitch is varied. A control lever 27 (Fig. 4, not shown), is provided so that movement of the rudder bar 25 controls the rudder position or the propeller pitch as required. The lever 27 is pivoted at 31 and has fixed to it two camplates 34, 35 containing arcuate slots 37, 40 centred on 31, and slots 38, 41 joined to the slots 37, 40 respectively. Cam-follower rods 42, 43 are connected by pins to the slots in the cam-plates 34, 35 and by levers 51, 52 to control rods 62, 64 which vary the propeller pitch and rudder position respectively. Movement of the lever 27 clockwise, to the lower position, causes the rod 43 to be lowered by slot 41 and the rod 64, connected to the rudder to be actuated. Movement of the lever 27 anti-clockwise to the forward flight position, conversely causes the rod 62, connected to the propeller pitch control, to be actuated. The rudder bar is connected to two bell-cranks 65, 66 pivoted at 67, 68 and having guides 81, 82 in their upper arms for rods 77, 78. Movement of the lever 27 to either extreme position causes the rods 77, 78 to be moved to an extreme position of the guides, so that one rod is adjacent to a pivot 67, 68 and movement of the rudder bar affects only the pitch (in the lower position, by actuating rod 77, lever 57 and rod 62), or the rudder (in the forward flight position). In another embodiment (Fig. 5, not shown), the cams 34, 35 are replaced by two arms depending from the lever 27, each connected by a rod directly to a lever 51 or 52.
