Abstract: 1,086,900. Electric analogue calculating. BOFORS A.B. Dec. 31, 1964 [Jan. 15, 1964], No. 53045/64. Heading G4G. In the radar controlled gunnery system shown the aerial tracks the target automatically under the control of servomotors RS, RH which provide azimuth angle and rate of change of azimuth angle signals SV 1  and SV 1  and corresponding vertical angle signals RV 1  and RV 1  while a transmitter receiver unit provides range and range rate signals AL 1  and AL 1 . These signals are fed to a computer EI which develops the azimuth and vertical angles to control the gun. The system, however, is subject to errors produced by mechanical imperfections, fading of signals &c. which primarily affect the rate signals and the invention is concerned with eliminating these imperfections by the use of filters FS, FH in the azimuth rate SV 1  and vertical rate hV 1  signal path, these filters being also fed with acceleration signals developed in a further computer C to compensate the filter output for the time taken for the signal to pass through it. In order to develop these acceleration signals, computer C is fed with the outputs of the filters (the corrected rate signals), the azimuth and vertical angle signals and the range and range rate signals, the acceleration signals S#V 1  and L#V 1  being fed back to the appropriate filters. Fig. 2 shows a filter construction for A.C. signals. The un corrected rate signal S#Vi 1  is applied to integrating circuit 7, 6 and through resistor 5 to an amplifier F with a capacitive feedback network 3 acting as an integrator, the acceleration signal #Vi being applied to this amplifier input. The corrected amplifier output S#V 1 u is applied to condenser 6 as a negative feedback signal and subtracted from the input signal by resistance network 7, 5, 9. A further arrangement is described with reference to Fig. 3 (not shown) in which the amplifier F is replaced by a servoloop consisting of a modulator servo-amplifier and servomotor, the filtered output appearing as the angle of rotation of a shaft. This rotation positions one D.C. potentiometer to provide the feedback signal through capacitor 3 and another fed with both A.C. and D.C. which develops the D.C. feedback signal through resistor 9 and an A.C. signal to operate the various computer circuits. Acceleration computer.-Acceleration S#V may be represented by and the derivation of these quantities is described with reference to Fig. 4 (not shown). A reference A.C. is applied at (20) and the range rate signal #Al 1  at (21). The reference A.C. is fed through a potentiometer coupled to a range rate servo incorporated in the filter. The output S#V 1  is then fed through a resolver R 1  fed with hV 1  so that the output is S#V 1  sin hV 1 . This is repeated at potentiometer P 2  coupled to the radar elevating servo as as to give S#V 1  sin hV 1  cos hV 1 . The whole is multiplied at potentiometer P 3  to give S#V 1 <SP>2</SP> sin hV 1  cos/hV 1 , in a similar manner hV 1 (Al 1 /Al) is developed from   the input #Al 1  and the two signals added at 22 to give h#Vi. A similar process produces S#V 1 .

Abstract: 1,095,351. Polyolefins. IMPERIAL CHEMICAL INDUSTRIES Ltd. April 30, 1965 [May 4, 1964; June 8, 1964], No. 18427/64 and 23600/64. Heading C3P. The properties of stereoregular polyolefins are improved by incorporating therein a substituted olefin polymer which has been prepared by reacting a chlorinated olefin polymer with an effective agent, i.e. a compound imparting the desired property and having an hydroxyl group reactive with the chlorinated olefin polymer, under basic or neutral conditions. The stereoregular polyolefin may be isotactic polypropylene. The modifier may be prepared by reacting polypropylene with chlorine in tetrachlorethane in the presence of a catalyst or ultra-violet light, and reacting the chlorinated product with effective agents such as hydroxybenzophenone ultra-violet light absorbers. The polyolefins may be made into films. In an example isotactic polypropylene is chlorinated and reacted with 2,4-dihydroxybenzophenone and the product incorporated in isotactic polypropylene which is pressed into a film.

Abstract: 1,226,991. Ejection seats. HONEYWELL Ltd. 17 April, 1969 [12 March, 1968], No. 11967/68. Heading B7G. An ejection seat comprises propulsion means 4, 7 at each side of the seat 1, each propulsion means being able to eject a high velocity stream in either of two generally downward directions, one direction having a forward component and the other a backward component, and control apparatus 12-15 responsive to the output of pitch and yaw sensing means 10 and 11 to switch the propulsive streams between their two possible directions to oppose the sensed pitch and yaw movements. Sensing means 10 and 11 are pure fluid vortex sensors, and their outputs are summed by fluid summing amplifiers 21-24; considering the left half of Fig. 2, the outputs from summing amplifiers 21 and 22 cause a pressure difference between lines 25 and 26, thereby determining the mark/space ratio of fluid bi-stable oscillator 12. The oscillator mark output appears at 12a, and the space output at 12b, and both are amplified by a fluid amplifiee cascade 14 and fed, at 14a, 14b, to opposite sides of bifurcated propulsion nozzle 4. The fluid flow along lines 14a, 14b deflects the main propulsive stream between bifurcations 5 or 6, the amount of time the stream passes through each bifurcation depending on the mark/space ratio; the sensed pitch and yaw movements may thus be opposed, using nozzle 4 in conjunction with similarly operated nozzle 7. Vortex sensors 10, 11, require an integrating component (not shown), as they are rate sensors. The fluid control system may operate from a pressurized air supply; the fluid control system may also be replaced by electromechanical sensors, electronic amplifiers and oscillators and electromechanical deflecting vanes. Nozzles 4 and 7 may be connected to a single rocket unit, or to separate rockets 2, 3. The mean thrust of nozzles 4 and 7 may be displaced slightly forwards or backwards from the yaw axis to cornpensate for any known tendency of seat 1 to pitch or yaw, but this would generate small rolling moments.

Abstract: 1,228,695. Pneumatic tyres. SEMPERIT A.G. 2 April, 1969 [10 April, 1968], No. 17145/69. Heading B7C. A pneumatic tyre is provided with breaker layer inserts of cords which are formed of twisted yarns each consisting of a number of twisted textile threads, the twist of both the threads in the yarns and of the yarns in the cords being given by the formula where W is the number of turns per metre length and T the denier multiplied by the number of threads per yarn or yarns per cord; and in which the number of threads per 10 cm. at the crown of the tyre measured perpendicularly to the direction of the individual threads is given by the formula where C is the number of threads.
