Title: Method and system for launching projectiles
Inventor: CULLINANE JAMES FARWELL
IPC: F42B10/26
Filed: 1968-12-11
Abstract: 1,213,389. Weapons; projectiles. FMC CORP. 11 Dec., 1968 [14 Dec., 1967], No. 58771/68. Headings F3A and F3C. A device for dispersing a plurality of projectiles 94 comprises means for releasably coupling the projectiles together, means for spinning the projectiles about a spin axis A while they are restrained from radial movement with respect to the spin axis such that, on release of the restraint the projectiles disperse. In the construction shown the straining means comprises a launching tube 27 which is mounted for rotation in a casing 21. The lower end of the tube 27 is closed by a base-plate 41 which is mounted for rotation in a pivotable breech plate 28. A solenoid-actuated firing pin 85 is located in the base-plate 41. The breech plate 28 is locked in its closed position by spring- urged fingers 34 of the plate co-operating with the head of a stud 31 of a mounting block 30 arranged on the casing. The launching tube 27 is rotated by an electric motor 42 through gearing and a driving band 53. The shaft 43 of the motor 42 can also be rotated manually through a handle 61. The projectiles are releasably coupled by a pin 96 arranged adjacent the periphery of one projectile co-operating with an open-ended slot( 97 of an adjacent projectile. The launching tube is loaded through the base thereof a stack of releasably coupled projectiles being mounted on a charge plate 75 secured in a tube 74 for this purpose. The charge plate 75 contains a primer 88 and a main charge 79, the latter being held in the charge plate 75 by an annular diaphragm 80. A cap 28 is placed on the stack of projectiles. The rotating projectiles 94, on being urged from the launching tube 27 by the explosion of the charge 79 and because their centres of gravity are displaced from the spin axis, pivot about pins 96 until the projectiles separate whence the projectiles begin to spin about their own axes again (Figs. 4 to 10, not shown). In a further embodiment (Fig. 1, not shown) the spinning projectiles are urged from the launching tube by a manually operated screw, an apertured, angularly adjustable face being provided at the upper end of the launching tube to determine the direction of projection of the projectiles. The motor may be omitted and the projectiles be caused to spin by rifling in a stationary launching tube. (Figs. 12, 13, not shown) or the launching tube may be provided with a concentric, spirally grooved axle which co-operates with an aperture in each projectile (Figs. 23, 24, not shown). These devices may be housed in a tank turret (Fig. 1, not shown). If, however, the device is required to project the projectiles downwardly, as from a helicopter (Fig. 14, not shown), a stack of releasably connected projectiles are mounted between an end plate and a jet spinner motor, the plate and motor being rotatably mounted about a tube. The motor is driven by an exploded charge and the charge for projecting the spinning assembly from the device comprises a delayed action charge (Figs. 15 to 21, not shown).

Filed: 1973-12-20
Abstract: 1422458 Measuring speed electrically VAPOR CORP 20 Dec 1973 [29 May 1973] 59019/73 Heading G1N A tachometer for use on an axle of a vehicle produces a pulse train whose frequency is proportional to angular velocity and is converted to an analog voltage. The pulse train induced in a pick-up coil 24 (Fig. 6) is squared at 50 to form pulse train 61 (Fig. 7) and fed to a monostable multi-vibrator 52 to form pulse train 62. Pulses 61, 62 control charge and discharge circuits 55, 53 via AND gate 51, whereby a capacitor in integrator 54 is quickly charged to a pre-set voltage via circuit 55 and then fed with a dischage current via circuit 53 for intervals determined by the durations of the pulses 61, 62, the resulting capacitor voltage being shown by curve 64. When discharge ceases, the capacitor voltage is indicative of the frequency of the pulse trains and is fed out via a memory device 57 for indication and control use. An acceleration signal is developed by a differentiator 59. The output signal voltage is indicative of the percentage divergence from a corresponding reference speed. To obtain a direct indication of the speed divergence, the duration of the pulses fed to the memory device 57 is controlled by a variable width pulse generator 60 in accordance with the output speed signal voltage. To emphasise this relationship the discharge current of circuit 53 is derived from the speed signal voltage.
