Patent GB-1358214-A (GB)
Title: Electronic projectilefuze
IPC: F42C13/00
Filed: 1972-08-07
Abstract: 1358214 Time delay circuits DIEHL 7 Aug 1972 [28 Aug 1971] 36751/72 Heading H3T [Also in Division F3] An electric fuze for a projectile comprises self-destruction means timed by the polarity reversal of one capacitor by charge flow from another. Upon launching a projectile current is supplied from the cell K2 to a capacitor C 2 , whilst current from cell K1 is dissipated through a diode D 2 . A negative charge is thereby established at point A and this blocks a transistor T 1 . When the acceleration phase of the projectile is over, the cell K1 supplies a capacitor C 1  with a charge which produces a positive potential at point B, whilst the cell K2 meanwhile charges a further capacitor C 3 . Charge flows from capacitor C 1  to C 2  through resistance R 1  and the polarity of capacitor C 2  is gradually reversed until the transistor T 1  is no longer blocked and current flows through both transistors T 1  and T 2 , causing thyristor T h  to conduct and allow the capacitor C 3  to discharge through detonator Z. If impact occurs before the self-destruction delay period is over, then the thyristor is rendered conductive by a charge developed in the piezoelectric cell P at impact. The Zener diode ZD limits the charge fed to the capacitor C 2  to a level less than that supplied to the capacitor C 1 , irrespective of the amount of charge generated. A Zener diode may also be associated with the capacitor C 1 . The charges may be generated electromagnetically instead of piezoelectrically.

Title: Programme control of machines

Abstract: 845,296. Photo-electric control. FERNSEH G.m.b.H. Dec. 14, 1956 [Dec. 16, 1955], No. 38212/56. Class 40(3). [Also in Group XXXVIII] The operation of a machine is controlled by superimposing on an image of the workpiece an image of a filmed programme of the workpiece and using a  photo-electric comparison of the images to control the machine. An image of the workpiece is focused by a lens 1 on to an electrostatic image convertor 2. An image of the convertor's luminescent screen is projected on to a negative film 8 which comprises a record of the workpiece programme. Light passing through the film 8 thus represents the difference between the actual and programmed workpiece. A photomultiplier 7 detects this difference and transmits it in the form of pulses through a frequency separator 12 to two phase detectors 13, 14 which generate positive or negative direct currents according to whether a given frequency leads or lags in phase as compared with comparison frequencies generated in oscillation generators 10, 11. The resultant signals are used to control the movements of the tool or workpiece. The oscillators 10, 11 are also connected to two deflector coils 3, 4 to produce a magnetic field in the image convertor which periodically shifts the position of the electron image on the lumniscent screen. When the images agree a signal is fed to a relay circuit 15 to trip the forward movement of the film to the next picture by an electromechanical drive 9. Both the workpiece and film may alternatively be scanned by television cameras.

In an air classifier comprising a vortex chamber 6, Fig. 3, to which granular solid material 3 to be classified according to size and/or specific gravity is supplied, a conduit 8 for classifying air 1, which imparts a vortex motion to the material, is tangential to the direction of the vortex formed in the chamber 6 extends beyond the chamber and is in open communication therewith, the conduit having an aperture 9 at the side opposite the chamber for the discharge of coarse and/or heavy particles of material. Part of the classifying air enters the chamber 6 and creates therein a vortex flow 2 which effects preliminary separation of the material. On leaving the chamber 6, the coarse and/or heavy particles are discharged through the aperture 4 into a compartment 10 due to the greater effect of the centrifugal force exerted upon them whereas the fine and/or light particles are entrained into the extended part of the conduit 8 by the main flow of classifying air. In another embodiment, Fig. 4, the classifying air 12 is fed through a conduit 13. A portion I of the air branches into an annular passage 8<SP>1</SP> which communicates with an annular vortex chamber 6<SP>1</SP> and extends upwardly into an annular passage 32 for fine and/or light particles. The remaining air flows upwardly through a passage 17 in a stationary body 16.

The material entrained into the air enters the vortex chamber 6<SP>1</SP> through a tangential inlet 28. The coarse and/or heavy particles are discharged through an aperture 9<SP>1</SP> into an annular passage 101 leading to a discharge pipe 30.
