Abstract: 1,053,391. Sighting devices. RHEINSTAHL HENSCHEL A.G. March 17, 1964 [May 18. 1963], No. 11252/64. Heading F3C. A sighting or aiming device comprises an aiming post mounted on the roof of a weaponcarrying vehicle to permit the position of the securing point for the aiming post to be adjusted to compensate for longitudinal and transverse inclinations of the vehicle from the horizontal. The post can thereby be set to a vertical position in relation to a fixed terrestrial system of co-ordinates in such manner that a downward projection of the axis of the aiming post intersects an imaginary horizontal fixed terrestrial plane which extends through the centre of a spherical support of the weapon at all inclinations of the vehicle at the point determined for firing of the weapon from that horizontal plane. In one embodiment the post is inserted in one of a number of holes in the vehicle roof, each hole being marked with the respective value of transverse and longitudinal inclination. In another embodiment the post may be mounted as a pendulum in a gimbal on a cross-support having two parts movable at right angles and representing a set of Cartesian co-ordinates. In a further embodiment the post is mounted as a pendulum in a gimbal on a slide which moves along an arm pivoted about a vertical axis so that the arrangement corresponds to a set of polar co-ordinates. In the last two embodiments the post may be adjusted automatically by electric motors controlled by potentiometers, the slides of which are operated by gravitational pendulums.

[Also in Division G6] The invention relates to a gas turbine plant associated with a nuclear reactor, the turbine plant operating on a closed circuit with CO 2  as the working fluid, there being at least two turbine expansion stages with reheat between the stages by heat from the nuclear reactor, the useful power being supplied by the low-pressure turbine stage. A branch line is connected to the working fluid circuit through which part of the working fluid is tapped off and cooled being thereby liquefied, the liquid C0 2  being then pressurized and returned to the circuit. A line is also provided connecting the branch line downstream of the cooler with a point in the circuit upstream of the reactor, the line being closable. In the embodiment shown, the plant comprises firstly an HP turbine 7 which drives an IP compressor 3, and HP compressor 5 and a liquid C0 2  pump 13, secondly, an LP turbine 9 which drives an LP compressor 1 also a useful load in the form of an electric generator 15, and thirdly, a nuclear reactor 8. Gaseous CO 2  is compressed in LP compressor 1, cooled in inter-stage cooler 2 and then further compressed in IP compressor 3. The C0 2  is then divided into two streams, one passing to HP compressor 5 thence through heater 6 where it is heated by CO 2  discharging from the LP turbine 9, the heated C0 2  then passing to the HP turbine 7. The C0 2  discharging from the turbine 7 is then reheated in the nuclear reactor 8 and passed to the LP turbine 9, the C0 2  discharging from the turbine passing through cooler 6, a second cooler 14 and a third cooler 10, the cooled gas finally passing back into the LP compressor 1. The second portion of C0 2  from the IP compressor 3 is passed to a first cooler 11 and then to a second cooler 12 where it is liquefied, the liquid CO 2  then passing to a pump 13 where its pressure is increased and the CO 2  is changed back to the gaseous phase, the gaseous C0 2  then passing to the heat exchanger 14 where it is utilised to cool the C0 2  discharged from the LP turbine 9, the C0 2  then passing to the point 28 where it rejoins the C0 2  delivered by the HP compressor 5. A line 50 is provided inter-connecting the liquid CO 2  line downstream of the cooler 12 with the C0 2  line between the HP turbine 7 and the nuclear reactor 8, the line 50 being closable by a valve 51 which is operable byadevice 45 responsive to the gas pressure upstream of the reactor.

Alternatively, fuel injection of the I.C. engine may be controlled by this apparatus. In Fig. 2 (not shown) fuel injection is controlled by the position of a butterfly valve in the intake manifold as adjusted by a foot pedal. Ignition timing may be controlled by the position of the butterfly valve. Alternatively, the ignition timing and fuel injection may be controlled by the engine speed via a centrifugal governor rotated with the crank-shaft operating on the member 15 of the transducer of Fig.1 or 2 (not shown). In Fig.3 (not shown), variations in the position of the rear axle relative to the vehicle body due to loading are used to alter the position of the vehicle headlights to maintain them at a constant position relative to the road.
