Title: An improved corrector device, particularly a sighting corrector device for firing ata moving target
IPC: F41G5/00
Filed: 1945-09-20
Abstract: 601,402. Gunsight predicting mechanism. BOYSSON, J. B. A. DE. Sept. 20, 1945, No. 24341. Convention date, July 11, 1944. [Class 92 (ii)] [Also in Group XXXVIII] In a system for deriving the product of two quantities, e.g. angular speed of a target and time-of-flight, a variable ratio is introduced between a device measuring precession of a gyroscope and apparatus controlled by an electric circuit the tuning of which is altered by the device. In Fig. 2 a rate-of-turn gyro (not shown) is maintained in the direction of a target, angular velocity of which relative to the firing point results in precession of the gyro, restrained by springs 11 and 11a, to adjust the position of a movable condenser plate 8 relative to a fixed plate 9, thereby altering the frequency of an oscillator 14 and causing movement of a pointer 23 of a meter, responsive to oscillator frequency, serving as an aim indicator. Range correction is introduced by movement of a handwheel 19 to change, through gearing, the relative position of plates 15, 15a of a second condenser controlling oscillator frequency so as to alter the ratio of aim indicator deflection to rate of turn. Handwheel 19 also adjusts, through gearing, the position of scale 30 of the aim indicator to preserve a true zero. An electrical transmission involving a servomotor 25 operates a second aim indicator 28. In modifications, Figs. 3 and 4 (not shown), range correction is introduced mechanically by altering the position of the fulcrum of a lever coupling the gyro to its associated condenser or of a lever coupling the servomotor to the second aim indicator. The following modifications are also referred to :- (a) Range correction introduced directly into the first aim indicator. (b) Introduction of other corrections by the handwheel. (c) Automatic range correction. (d) A system for indicating aim about perpendicular axes utilizing one or two gyros.

Class 38(5) [Also in Group XVIII] A signalling device for use in vehicles comprises a casing in which are housed, a shaft adapted to be rotated continuously, an electric lamp or lamps, an electric battery or batteries, an electric circuit or circuits adapted to connect said lamp or lamps and said battery or batteries, and interrupter means operable by the continuous rotation of the said shaft to open and close said circuit or circuits intermittently, to cause said lamp or lamps to flash intermittently. As shown the casing is attached to the free end of a cycle pedal and contains a battery 109, a white lamp 108 and a red lamp 107. A commutator 115 is fixed to the pedal shaft and this is connected to the battery by a pivoted member 112 and to the lamps by pivoted members 120, 121. The pedal is weighted so that normally the white lamp points forwardly and the red lamp rearwardly arid in this position gravity keeps the members 112, 120, 121 in contact with the commutator so that as the pedal rotates relative to its shaft the lamps are flashed sequentially. When the pedal is reversed the members 112, 120, 121 fall away from the commutator so that the lamps are not illuminated. In a modification each lamp has its own battery and these are housed in the hollow spindles for the rubber treads. The lamps in this construction are arranged to flash synchronously. In a further modification cam actuated switches are used instead of a commutator.
