Patent GB-475090-A (GB)
Abstract: 475,090. Directive wireless signalling. KRUESI, G. G. Feb. 7, 1936, No. 29498/37. Convention date, Feb. 8, 1935. Divided out of 474,972. [Class 40 (v)] Relates to direction-finding systems of the type described in U.S.A. Specification 1,868,945, and British Specifications 452,651* and 474,972, in which the pick-up from a directional and non-directional aerial is combined with a locally-produced oscillation through a balanced modulator to produce a cardioid field-curve which is then periodically reversed in polarity so as to indicate the desired direction. According to the invention means are provided to eliminate from the indicator (a) undesired frequencies from the modulator, (b) ordinary or artificial static disturbances. This is secured by tuning both the moving-coil and field-coil circuits of the indicator device E, Fig. 1, to the frequency of the local oscillator O<1> which feeds the balanced modulator B. The moving- coil E is tuned by inductance 76 and condenser 60, and the field-coil 46 by a condenser 62. In addition, the ratio of reactance to resistance is made the same in both circuits. The indicator needle is centred between two hair-springs 64, 66 located on each side of the moving-coil 44. A sluggish effect can be secured by shunting the condenser 60 with a resistance. A filter 74 is inserted in the plate circuit of the local oscillator O to prevent any leakage of the oscillations into the receiver D. The timing of the indicator circuits limits the effective response of the indicator to a narrow band of frequencies, thus reducing the effect of (a) undesired modulation frequencies, (b) variations in the frequencies of the local oscillation O caused say by fluctuations in the driving voltage from the slipstream generator on an aeroplane, and (c) static interference. The general circuit arrangements are similar to those described in Specification 474,972. The Specification as open to inspection under Sect. 91 also comprises certain features which are contained in Specification 474,972. This subject-matter does not appear in the Specification as accepted.

Title: A toy in the form of a rocket missile
IPC: A63H27/00
Filed: 1963-12-04
Abstract: 1,045,480. Toy aircraft. A. QUERCETTI. Dec. 4, 1963 [Jan. 15, 1963], No. 47879/63. Heading B7W. [Also in Division A6] A toy missile, comprising two parts 1, 2, hinged together at 3 and a nose section 7, has a device which causes the missile to completely open in a predetermined position of free fall to permit the escape and release of any objects which the missile carries, e.g. a parachute. The missile is launched with lever arm 26, 28 in the position indicated by broken lines, whilst the shorter end 26 of the arm contacts a catch 21 of the part 2, thus keeping the parts locked together. Upon initial launching the lever arm 28 is forced into the full-line position of Fig. 5 by aerodynamic forces. As the missile ascends the force of elastic cord 23 upon the catch 21 overcomes the aerodynamic forces and causes the lever 28 to pivot away from the fixed part 1 thereby releasing the catch 21 and unlocking the part 2. The missile does not completely open since the tension of elastic cord 16 overcomes the resistance of a lever 9 pivotally connected to part 1 and acting on a stop 9A of part 2. Upon free falling descent the aerodynamic forces acting on fins 11 (Fig. 1, not shown), and 20, and resistance of the lever 9 overcome the tension of cord 16 and cause the missile to be completely opened and permit release of a parachute carried therein. The tensions in the cord 16, 23 may be adjusted by the positioning of elements 17, 24 in the notches of rack 18. A capsule 34 (Fig. 6), with a transparent section 35 and shock-absorbing nose cap 36 can be frictionally fitted to the nose section 7, and upon abrupt retardation of the missile the capsule may become detached. A launching pad 40 comprises a foot rest and a recess 43 into which can be slid a holding bar 44. After creating a tension in the catapult (Fig. 7a, not shown), the foot is raised slightly and head 45 of the bar 44 slides out of the recess 43, whereupon the missile is launched.

Filed: 1968-10-10
Abstract: 1281163 Image detector array PLESSEY CO Ltd 11 Sept 1969 [10 Oct 1968] 48158/68 Heading H4F The output signal from an image detector array is modified to reduce the effect of faulty photoelements in the array by detecting faulty signal levels caused by these elements using a threshold circuit and causing the signal level immediately preceding each faulty level to be maintained during the occurrence thereof. A faulty element introduces either an absolutely white or absolute black voltage level in the output signal, and these are detected and applied to the gate of a MOST Ml, Fig. 2, to the source electrode of which is fed the video signal from the array. The drain of M1 is connected to the gate at MOST M2. The drain of M2 is connected to earth and an inherent electrode capacitance C between the gate and earth can be used to store a video signal voltage level. In operation a noise suppression pulse is generated if a faulty voltage level is detected, and in response thereto M1 is turned off and the video output level is stored on C. The threshold circuit is also arranged to detect the synchronizing pulses, whose levels are below that which could be reached by a faulty element, so that flyback blanking pulses may be added to the video output signal. The black and white faulty voltage threshold levels may be adjustable to allow for changes in intensity of the image projected on the array, and only one instead of both levels may be applied.

Patent GB-496006-A (GB)
Abstract: 496,006. Indicating vibrations. SARAZIN, R. R. R. Dec. 7, 1937, No. 33911. Convention date, May 7. [Classes 106 (ii) and 106 (iv)] A vibration-sensitive device comprises a rotary shaft subjected axially to the vibration, a pendular system connected to said shaft in such manner as to enter into oscillation under the effect of the vibration, and means to indicate the amplitude of the vibration. The device is described as applied to testing the balance of a crank shaft. A frame 2 pivoting about an axis 4 is kept in a normal position by a spring 7. The frame carries bearings 5, 6 for the crank shaft 1 the balance of which is to be tested and an electric motor 8 for driving the shaft 1. The vibration-sensitive device 9 is carried by a support 10 on the frame 2. In the support 10 is journalled a shaft 11 driven by bevel gears from the motor shaft 13. Conical roller thrust bearings 15, 16 subject to the action of a spring 17 and a guiding ball bearing 14 are provided for the shaft 11 as shown. A part 20 carried by the shaft 11 supports on knife edges 19 two pendulum masses 18, 18<1> geared together by meshing toothed quadrants 22, 22<1>. These parts are contained in a circular casing 23 provided with a cover 24. When the frame vibrates under the unbalanced forces in the haft 1, the masses 18, 18<1> oscillate between two extreme positions shown as OX, OY for mass 18. The cover is provided with a transparent part 26 provided with an angular graduation in degrees and a radial graduation giving the inclination of the pivoting elements 18, 18<1> in either side of their position of equilibrium corresponding to the circle marked zero. One element carries a needle 25 at rightangles to the pendulum arm. This needle describes a closed curve which intersects the zero circle at points a b and which passes through maximum and minimum points c d located on a line at right-angles to a b. The point c corresponds to the passage of the unbalanced mass through the lowest point in its travel and point c to the highest point. If one crank arm has been placed vertically to begin with and at the same time the needle 25 is brought in to the " zero " of the angular graduation, the angular position of the unbalanced mass may be determined. This with the radial distance of c enables the amount and position of the unbalanced mass to be calculated. The device may be applied to the measurement of vibrations say of an aeroplane wing under the action of the engine. It is rotated at different speeds until the appearance of the curve trued out by the pointer becomes definite and corresponds to the frequency proper under investigation or to an harmonic thereof.
