| Number | Title | Issue Date |
| 7367268 | Safety and arming device for a spinning projectile fuze A safety and arming device (10) for a spinning projectile fuze, which has a fuze housing (12), which is in the form of a pot, and a bearing body (14) with a booster charge (16). A spherical rotor (42) with a detonator (44) i... | 05/06/2008 |
| 7013809 | Mecanotronic fuses for hand grenades The improvements are applicable to fuses provided with a container (9) inside which may move axially a slider (10) having an electrical generator (1), the activation of which provides the electrical energy required for the operation of the fuse,... | 03/21/2006 |
| 6142080 | Spin-decay self-destruct fuze Apparatus mountable in a projectile for utilization with a rotor-type safing and arming mechanism for post-launch self-neutralization of a spinning projectile having a fused warhead and a stab detonator, including a launch-activated battery, an electric d... | 11/07/2000 |
| 5355801 | Small caliber fuze with arming delay, second impact and graze sensitivity The objectives of these inventions are to provide simple, reliable, and low-cost mechanical means to obtain (1) second impact detonation and (2) substantial safe arming separation from the gun for point detonating fuzes for small caliber spin stabilized s... | 10/18/1994 |
| 4969397 | Grenade-type projectile A grenade projectile has a projectile housing having a fragmentation length portion; an explosive charge accommodated in the projectile housing and being surrounded by the fragmentation length portion; a forwardly acting shaped charge liner bounding the e... | 11/13/1990 |
| 4694752 | Fuze actuating method having an adaptive time delay This is a method for an adaptive delay time after impact of a projectile by determining the spin rate of the projectile using spin switches to set a time delay which may then be updated using a time of flight counter. This method may be used on artillery ... | 09/22/1987 |
| 4620483 | Missile safe and arm system A missile safe and arm system incorporates an electrically triggered explosive train that extends from the missile body to an extendable probe and back to the missile body. When the probe is in its retracted position, the explosive train, and electrical t... | 11/04/1986 |
| 4464992 | Sector type initiator for artillery projectiles Impact with a resistant media at adequate forward velocity and rate of rotation causes a pivoted sector weight to shear a retaining shear pin and rotate quickly, bringing a firing pin on the sector weight into violent contact with a percussion primer and ... | 08/14/1984 |
| 4378740 | Munition fuse system having out-of-line safety device An out-of-line fuse for primarily ring-type, multiple point concurrent initiation, projectiles is disclosed. In the unarmed state, the detonator and booster charges are angularly displaced while located at the same radial distance from the projectile axis... | 04/05/1983 |
| 4213395 | Ball rotor safety and arming delay device The ball rotor safety and arming device of this invention includes means for rendering the friction forces which effect the alignment time of the ball rotor more reproducible and controllable reducing the dispersion of arming distances of the device and i... | 07/22/1980 |
| 4004521 | Projectile fuze A graze sensitive and self destruct fuze arrangement for a point detonating pin stabilized projectile in which assured detonation is achieved by nose or point impact with a target, by graze impact with a target, or by self destruction capability upon failu... | 01/25/1977 |
| 3995557 | Base fuze for a spinning projectile A base fuze for a spinning projectile comprising a firing pin for piercing a detonator cap, a hammer sleeve secured to the firing pin, a self-destruction spring by means of which the hammer sleeve together with the firing pin can be displaced towards the ... | 12/07/1976 |
| 3994230 | Self-destruction type nose impact fuze for spinning projectiles A self-destruction-type nose impact fuze for spinning projectiles comprising an axially displaceable firing pin which can be brought to bear at an axially displaceable impact body against the force of a self-destruction spring through the agency of centri... | 11/30/1976 |
| 3949675 | Projectile A point detonating, high explosive incendiary projectile having a safe self estruct fuze that is operative only after setback and spin forces have been imparted to the launched projectile. The fuze includes a rotor housing that is slidable in and spring bi... | 04/13/1976 |
