Patent GB-827532-A (GB)
Abstract: 827,532. Gun - sighting apparatus. JOYAU, G. March 19, 1956 [March 18, 1955], No. 8505/56. Class 92 Relates to a device for the aiming of a gun turret on a mobile airborne target. The mathematical basis for the device is as follows:-In Fig. 1, A 0  is the target, O the position of the gun turret, S 0  the angle of elevation or sight, G 0  the bearing angle, D 0  the range OA 0 , A is the future position of the target which must be aimed at in order to hit the target, A 0 OA is the plane of flight making an angle γ (the angle of flight) with the vertical plane OA 0 a 0 , #=A 0 ¶A is the angle of lead. # is the angular velocity of the target in the plane of flight. If S 0 <SP>1</SP> and G 0 <SP>1</SP> are the angular velocities of the target in elevation and bearing respectively, then- It can also be shown that- -where #(D 0 , D<SP>1</SP> 0 ) corresponds as a first approximation to the average speed of the projectile. In the device the gun layer tracks the target and the values γ and # are set in by hand respectively at 1 and 2, Fig. 2, the aiming turret being driven in elevation by a motor 12 whose speed is controlled by potentiometer and computer mechanism 3, 6, 9 according to the formula S<SP>1</SP> 0 =# cos γ, the turret also being driven in azimuth by another motor 20 whose speed is controlled by potentiometer and computer mechanism 7, 15 according to the formula G<SP>1</SP>0 = # sin γ/cos S 0 .  The angular velocity # is also fed by handle 2 to potentiometers 22, 24 and the range D, from an optical or radar range finder is fed to a potentiometer 24 by a shaft 26 which drives a two-dimensional camoid representing the function f(D 0 , D<SP>1</SP> 0 ). By means of further potentiometer and computer mechanism 29, 31, 33 a voltage proportional to # D 0 /#(D 0 ,D<SP>1</SP> 0 ) is produced and f(D 0 , D<SP>1</SP> 0 ) controls a motor 35 which thus measures the angle of lead 8 according to the formula (c), and serves to displace the gun accordingly. Fig. 3 shows the computing device controlling the potentiometer 7, Fig. 2. The slider 14, Fig. 3 of the potentiometer is fixed to an alidade 15 which can move parallel to itself along slides 39, 40. The amplitude of this displacement is controlled by a lug 44 sliding in the alidade 15 and carried by a sleeve 41 which itself slides on an arm 16 rotatable about an axis 42. The sleeve 41 carries a second lug 43 sliding in a groove 17 of a cam 18 concentric to the axis 42. The arm 16 rotates at an angle γ and the cam rotates at an angle γ + S 0  and thus at an angle S 0  in relation to the arm 16. The groove 17 is calculated so that its distance to the axis 42 is equal to 1/cos S 0 . The arm 16 and the lug 44 thus form a crank arm whose length is 1/cos S 0  and which rotates with an angle γ. The displacement of the alidade 15 and of the slider 14 is thus   equal to Sin γ/cos S 0  and the voltage of the   slider equals # sin γ/cos S 0  which is the represion required by formula (b).

Title: Anionic polymerisation of conjugated dienes
Inventor: RICHARDS DAVID HUGH
IPC: C08F36/04
Filed: 1983-04-18
Abstract: A process for the anionic polymerisation of a conjugated 1,3- diene in a polar solvent consists of contacting the 1,3-diene with an organo alkali or alkaline earth metal initiator and a sterically hindered Lewis acid, allowing the 1,3-diene to polymerise in the polar solvent and terminating the polymerisation reaction. Preferably the Lewis acid is a substituted triaryl derivative of a Group III element, especially boron. However in certain cases (e.g. where the aryl derivative itself is large) the Lewis acid may be an unsubstituted triaryl derivative of a Group III element. Suitable Lewis acids include trimesityl boron and tri(2,6- dimethylphenyl) boron. In preferred embodiments of the present process the 1,3-diene is butadiene, the polar solvent is tetrahydrofuran and the initiator is a difunctional initiator, especially an electron transfer reagent.   The main advantages of the present process are that polymers with enhanced 1,4-content, a narrow molecular weight distribution and, in the case of telechelic polymers, with an enhanced difunctional specificity are obtained.
