Title: Improvements relating to radar optical-electrical correlation means
IPC: G01S13/58
Filed: 1968-04-11
Abstract: 1,208,665.  Correlation techniques. COMPAGNIE FRANCAISE THOMSON HOUSTONHOTCHKISS BRANDT. April 11, 1968 [April 19, 1967], No. 17670/68. Heading G1U. [Also in Division H4] In a radar (including any electromagnetic or sound wave) echo processing system, the echo signal modulates a radiation source, a record carries a code as variations of a radiation-affecting medium on the record, such variations are represented by substantially the same function in terms of a longitudinal co-ordinate of the record as the function representing the variations in the transmitted radar signal in terms of time, the record is displaced in a direction parallel to the longitudinal co-ordinate, and an array of radiation-sensitive devices are distributed parallel to the longitudinal co-ordinate. In one embodiment a diode 2 emits infrared radiation modulated by the output of a pulse Doppler radar receiver, the moving record medium 4 carries transparent areas e.g. 41 at intervals corresponding to a pulse repetition period, a fixed bank of photo-electric devices 5-1.... 5-ncorresponding to n range gates have their outputs passed through stationary-target rejection filters 6-1... 6n and the amplified filter outputs (weighted amplification may be utilized) energize light emitters 7-1...7n each producing a vertical fan beam when energized on to a moving Doppler-analyzing transparency 9 each longitudinal track of which represents a different Doppler shift. The final display may be directly visual, orthogonal co-ordinates of the spot seen representing target range and velocity or the light beyond a transparency 9 may be sent to a camera-type cathode-ray tube (C.R.T.). The principle of operation involves auto-correlation, the integration being over as many radar pulse-repetition periods as a target is illuminated per aerial scan. Optical fibres may be utilized. In the above arrangement with a C.R.T. no further information can be read on to it whilst reading-off is taking place; in modifications more than one set of Doppler-selection tracks is utilized, Figs.2, 3 (neither shown).

Title: Helicopter with tail-mounted rotor system for propulsion and yawing control
Inventor: KANNAMULLER GERHARD
IPC: B64C27/82
Filed: 1965-04-22
Abstract: 1,118,117. Controlling helicopters. DORNIER-WERKE G.m.b.H. 22 April, 1966 [22 April, 1965], No. 17706/66. Headings B7G and B7W. A helicopter has a tail mounted screw propeller rotatable about a longitudinal axis to produce forward thrust and provided with cyclic pitch control for yaw control. The propeller blades 12 are pivotally mounted, preferably by the hub which forms part of a constant velocity joint (Fig. 4, not shown) and is tilted by movement of a swashplate 13. The cyclic pitch variations thus change the plane of rotation of the blades, and the thrust direction (Figs. 3a, 3b, not shown). The pilot's rudder bar 16 operates the cyclic control and a rudder 22 immediately upstream of the propeller through a mixing unit 20 which varies the control movements applied to the rudder and swashplate in accordance with ram air pressure (i.e. forward speed), so that at cruising speed only the rudder is operated, but when hovering, both rudder and swashplate are operated. The mixing unit may additionally be controlled manually. The main rotor and tail propeller are driven by a gas turbine engine (2, Fig. 1, not shown), through a gear-box (3) with separate output shafts. Collective pitch control of the main rotor and the tail propeller are effected together by a pilot's control lever 23 and in the same sense. The collective pitch of the tail propeller may be increased automatically as the cyclic pitch increases to provide a sufficient range of yawing moment, and may also be varied independently by an electric motor 28 operated by a button 30 on the control column 29, to preserve an efficient balance between the forward thrusts produced by the main rotor and tail propeller. An instrument 31 indicates when a certain forward position of the column 29 has been reached. Control surfaces, wings.-A tailplane (8, Fig. 1, not shown) is located in the downwash of the main rotor; this is stated to prevent a sudden trim change as the helicopter accelerates from hovering flight. The helicopter is also supported during forward flight on wings (7), the lift of which can be varied by spoilers or flaps or by varying their incidence, e.g. so that sufficient body incidence can be attained to cause autorotation of the main rotor in the event of engine failure.

Title: Optically active 3-hydroxy-n-methyl-morphinanes and process for the manufacture thereof
Filed: 1953-06-26
Abstract: The optical isomers of 3-hydroxy-N-methylmorphinane are prepared by resolving 1-(p-methoxybenzyl)-2-methyl-1 : 2 : 3 : 4 : 5 : 6 : 7 : 8-octahydroisoquinoline by means of an optically active acid and cyclising the optical antipodes separately.  The latter may be isolated as tartrates which are subsequently converted into the free bases.  Resolution of the isoquinoline may be effected by fractional crystallization of the tartrate from water or methanol or a mixture of the two.  The tartrate which crystallizes first is laevorotatory in ether and (after conversion to the free base) gives the d-(+)-morphinane on cyclizing with phosphoric acid.  From the mother liquor is obtained the tartrate which is dextrorotatory in ether and this can be converted into free base and cyclised to the l-(-)-morphinane.  Alternatively the crude mother liquor can be cyclised directly and resolution completed at the morphinane stage. The process is exemplified.
