Abstract: 1428979 Projectile fuzes JUNGHANS GmbH Gebr 21 Sept 1972 [14 Oct 1971] 43824/72 Heading F3A An electric fuse, e.g. for a mortar shell, comprises an electric ignition element energizable from a storage capacitor, connection of the capacitor to the element being effected by a pulse-controlled electronic circuit. In one embodiment (Fig. 1, not shown) an ignition capacitor (11) is chargeable via terminals (19, 20) and, when connected to the ignition element (10) either via an inertia switch (13) or a safety switch (14) will ignite the element if outputs from a triggering stage (II) are delivered via terminals (24, 25). The triggering stage (II) comprises a Schmitt trigger circuit activatable through a Zener diode (ZD) the effective time-constant being determined by a capacitor (15) and variable resistor (16) in an input stage (I) and a resistor (RE). Pulses are supplied to terminals (18, 19) of the input stage (I) periodically to render conductive a switching transistor (17) causing discharge of the capacitor (15) until, when its voltage reaches the limit value of the input to the triggering stage (II), the latter is actuated. In another embodiment (Fig. 2, not shown) the triggering stage (II) comprises a differential amplifier (V). In other embodiments (Figs. 3 and 4, not shown) having modified input stages, a flip-flop circuit (FF) associated with a differential amplifier (V); and an 8-bit binary counter (B 1 , B 2 ) comprise the respective triggering stages. Various forms of pulse-generator are described. In one (Fig. 5, not shown) an escapement mechanism (37-39) controls oscillations of a balance wheel comprising two discs (31, 32) mounting magnets (33, 34) which produce pulses in a fixed coil (40). The balance wheel normally is restrained from oscillation by an arm (28) projecting from a starting device (26) which is retained in an inactive state by a pin (29). The pin (29) forms part of a known safety device which may be actuable by acceleration or centrifugal forces. Upon release by the pin (29) the starting device (26) pivots to release the balance wheel and simultaneously closes the ignition circuit safety switch (14). In another form (Fig. 6, not shown) pulses are derived from a simple multivibrator circuit once this is enabled by the starting device (26). In other forms (Figs. 7 and 8, not shown) escapement mechanisms control movements of leaf springs mounting either magnets which co-operate with a coil; or piezoelectric elements for generating pulses.

A navigational calculating device for use in aircraft comprises a first disc 10 having a compass scale marked round its periphery and a polar grid marked in the centre thereof, the grid comprising intersecting lines 16 radiating from a remote point and arcuate lines 17 centred on the same remote point, and a second disc 11 concentric with the first and rotatable relative thereto about a pivot 12, the disc 11 having a compass scale round its periphery co-operating with the scale round the disc 10 parts of the centre of the disc 11 being cut away to expose the polar grid, but leaving a radial strip 31 with an edge 29 radial to the pivot 12 having a linear scale 33 marked thereon the graduations of which bear a direct relationship to the spacing between adjacent arcuate lines 17 on the grid. The compass markings on the disc 10 are used to represent heading whilst those on the disc 11 represent wind direction, the scale 33 being marked for wind speed. The lines 16 of the grid are used to represent true course as an error to be algebraically summed to the heading value, the division between the positive and negative error values being the line 16 passing through the pivot 12. Similarly the lines 17 represent true air speed also as an error value, to the ground speed value, the line 17 passing through the pivot 12 again dividing positive and negative error values. By setting known heading and wind direction values to correspond on the two compass scales and knowing wind speed, against the wind speed value mark on the scale 33 can be read error values to enable true course and true air speed to be determined. Similarly knowing air speed, true course and heading, wind speed and direction can be determined. Other calculations are also possible. The two discs may be made of plastics, metal or cardboard.
