| 221 | Mortar fuse with a rotatable fan | US09856619 | 2001-09-12 | US06481354B1 | 2002-11-19 | Rainer Heck; Reiner Hennig; Frank Kienzler; Detlef Pabst; Jürgen Voigt; Wolfgang Zehnder |
| A mortar fuse includes a fan wheel rotated in response to motion of the mortar fuse after the mortar has been launched. The fan wheel rotates a helix on which an activation wheel is mounted. The activation wheel moves in a path along the axis of the helix in response to rotation of the helix and eventually impacts against, and pierces, an acid container. Battery acid flows from the container and into battery cells, to energize the battery. The activation wheel includes a magnetic material. A coil is disposed along the path of travel of the activation wheel so that electric energy is generated in the coil as the magnetic activation wheel moves therepast. The electric energy operates a counter which controls a time function of the mortar fuse. | ||||||

| 225 | Acceleration sensor | US662089 | 1984-10-18 | US4638130A | 1987-01-20 | Peter Grossler; Norbert Nissl |
| An acceleration sensor comprises a housing formed with a hollow cavity deing a sensing direction. An acceleration sensing conductive mass is releasably mounted in the cavity. The mass is released by a cutting member which severs the releasable mounting of the acceleration sensing mass. A force applying assembly is activated to cause movement of the cutting member. Switch electrodes are arranged at the lower end of the housing cavity. The mass falls through a predetermined distance and bridges the switch electrodes. The sensing mass, when severed, may move in incremental steps due to the use of a two-stage releasing assembly. Sensing transducers may be located along the falling path of the acceleration sensing conductive mass. | ||||||
| 226 | High energy switching circuit for initiator means or the like and method therefor | US591202 | 1984-03-19 | US4559875A | 1985-12-24 | William F. Marshall |
| A high energy switching circuit for an initiator, for example, an exploding bridgewire (EBW) or slapper-type detonator, includes a charged capacitor which is placed across a pair of series diodes connected in a reverse standoff voltage mode with respect to the capacitive voltage in series with an EBW initiator circuit. A switching field effect transistor is connected in shunt across the lower diode. In the armed condition, the pair of diodes clamp the high energy capacitor voltage at their reverse avalanche voltage. Upon the activation of the switching transistor, the capacitor voltage is impressed across the upper diode and a high reverse current flows through the upper diode placing it in destructive conduction which immediately also forces the other diode into destructive conduction to complete the series circuit from the capacitor to the EBW or slapper detonator. The circuit comprises low cost components and features very good firing simultaneity between similar firing circuits. | ||||||

| 229 | Dual output simultaneous firing circuit | US941092 | 1978-09-08 | US4227461A | 1980-10-14 | Dale L. Beezley; Wolf Goodman |
| A dual output simultaneous firing circuit which provides a means for explng fuse wires with a simultaneity of 20 to 200 nanoseconds even though the breakdown voltages of the fuse safety gaps have a large disparity. A DC voltage charges high voltage capacitors. When the charge voltage reaches the lower breakdown voltage of one safety gap, that fuse explodes. A balancing transformer induces momentarily an equal voltage which adds to the existing voltage on the undischarged capacitor. The additional charge breaks down the other safety gap causing the other fuse to explode. | ||||||

| 234 | Impact discriminating apparatus for missiles and the like, and method for impact discrimination | US594903 | 1975-07-10 | US4019440A | 1977-04-26 | Robert Strike |
| Impact discriminating apparatus for missiles and the like comprises a plurality of impact sensors disposed in spaced relationship along the longitudinal axis, and near the nose, of the missile. Sensors, responsive to elastic domain impact stress or shock waves, are separately fed into pulse generators wherein output pulses of different widths are formed for each sensor, overlapping pulses associated with all the sensors being generated for rearwardly propagated shock waves caused by a direct hit, but not for forwardly propagated shock waves caused, for example, by a stabilizer fin striking tree branches or other non-target objects. The generated pulses are fed to a NAND gate which is activated to cause fusing or detonation of the missile only by the overlapping pulses respresentative of a direct hit. Blanking circuitry blanks out effects of rearwardly propagated shock waves which are merely reflections of forwardly propagated shock waves, in order to prevent unintentional fusing or detonation. Pulse height discrimination is also provided to prevent unintentional fusing or detonation by low impact direct contact with such objects as foliage or raindrops or by low impact, glancing hits against tree branches and the like. A corresponding impact discrimination method is provided. | ||||||

An electrostatic switch is disclosed as an example of the voltage-responsive switch. | ||||||

| 237 | Pneumatic fuze for safing and arming missiles | US563766 | 1975-03-31 | US3967556A | 1976-07-06 | Lloyd D. Post; William J. Holley; William K. Clark; Fredrick R. Hayward |
| A pneumatic point detonating fuze utilizes the environmental parameters ofhe setback acceleration and projectile to accomplish safing and arming functions. Launch acceleration is utilized to unlock a fluidic system and allow it to respond to the air stream velocity. Upon completion of the arming cycle the fluidic system enables a mechanical-electrical fuzing system by closing electrical contacts and rotating out-of-line detonators so that they are in-line with an explosive train. A setback magnetic pulse generator operates at launch to charge a firing capacitor in an electronic switching circuit. Piezoelectric elements operate in conjunction with a trigger circuit to provide a firing signal at impact. | ||||||

| This invention makes use of the gas that escapes past a shell as it emergesrom a gun barrel to provide a safety and arming device. This gas is electrically active and has the properties of a plasma. Electrical charge from this gas accumulates on the surface of the projectile as it exits from the barrel. This accumulation takes place at the muzzle of the gun tube since the projectile is effectively grounded as it travels up the tube. The invention utilizes a specifically adapted capacitor to accumulate this charge and arm the fuze. Arming is provided by detecting a particular threshold of the charge on the capacitor and utilizing a standard "AND", "OR", or "NOR" gate to make the decision whether or not to initiate a standard mechanical arming mechanism. | ||||||
