Patent GB-2105662-A (GB)
Title: Four wheel steering of road vehicles
Inventor: BROWN FREDERICK JOHN
IPC: B62D7/15
Filed: 1981-05-29
Abstract: Mechanism for automatic all wheel steering of a road vehicle comprises an arrangement of gears which move the wheels to the required steering position. The gears are engaged first by a follower set when the steering wheel is operated by the driver. The gears then move, by a worm drive, the leading wheels of the vehicle into the required curve position and when the position is attained the follower disengages the gear. A second follower is connected to the front wheels and as they move engages another set of gears so that the rear wheels are set to an equal curvature as the front but in an angle opposite to that of the front in respect to the line of the vehicle and this follower disengages this gear as this position is attained. The rate of drive to both sets of gears is made variable and proportional to the angle of steering set by the driver so that the steering set of the wheels is attained in the same travel distance for all circles of steering and the gears and worm drive will be arranged so that this distance is the same as that between the leading and trailing wheels. <IMAGE>

Patent GB-2082688-A (GB)
Title: Axial fluid flow machines
IPC: F04D27/00
Filed: 1981-08-20
Abstract: The machine e.g. a fan, has a cylindrical housing (2) around a rotor (1), and a guide wheel (3) downstream of the rotor (1). Upstream or downstream of the latter there is a further auxiliary rotor (4), co-axial with rotor (1), and having blades of a smaller radial size. In the part of the hub of rotor (1) where flow separation is likely, for decreasing the deflection of the relative flow and for this reason for decreasing the blade grid loading, the supply of energy is decreased in the profile sections in question by decreasing the change in the circumferential velocity component of the absolute flow between the inlet and outlet of rotor (1). The auxiliary rotor (4) supplies further energy in these profile sections for keeping substantially constant the design- dependent energy amount in all blade sections. In a modification boundary layer aspiration is used in the region of potential flow separation. Rings (5,9) may be provided. <IMAGE>

Title: Frequency-selective circuit
Inventor: MOOREY ERNEST JAMES
IPC: G01R23/06
Filed: 1981-10-22
Abstract: A frequency-selective circuit for use in fail-safe equipment for the purpose of detecting component failure in an oscillator of the equipment comprises a signal processing stage (R6, R7, C6) arranged to produce a cyclically-varying intermediate signal with a mean D.C. value dependent on the frequency of an input signal, and switching circuitry (TR13, TR14) switchable between two states in dependence on the level of the intermediate signal, with hysteresis such that the level of the latter signal causing switching is dependent on the direction of switching. The overall arrangement of the circuit is such that only when the frequency of the input signal lies within a predetermined range will the intermediate signal have a mean level appropriate to cause the switching circuitry (TR13, TR14) to switch between its two states and thereby produce an output cyclically varying in correspondence with the A.C. ripple on the intermediate signal. <IMAGE>

Title: Xenon suppression in a nuclear fueled electric power generation system
Inventor: WATTS MARK G
IPC: G21D3/08
Filed: 1983-06-03
Abstract: The fissile inventory required in operating a negative power coefficient nuclear reactor in an electric power generating system is reduced by cycling the load imposed on the system when 100% power can no longer be maintained at equilibrium due to xenon poisoning in order to induce an oscillation in the xenon concentration which is in antiphase with the power requirements so that 100% power can be maintained at least during part of the day. The load can be progressively reduced by a preset amount each night or a xenon suppression controller which forecasts the xenon reactivity at the time selected for a return to full power as a function of reactor history, current reactor flux and an arbitrary load schedule can be used to determine the maximum reduced power level that will permit operation at full power at the selected time.
