| 1 | Muzzle velocity measuring apparatus and method | EP13198302.5 | 2013-12-19 | EP2749889A1 | 2014-07-02 | Jung, Kyu-Chae; Son, De-Rac; Shin, Jun-Goo; Lee, Sung-Min; Kim, Jung-Yun |
The present invention relates to an apparatus for measuring a muzzle velocity of a fired bullet so that the bullet may explode at an accurate location. The muzzle velocity measuring apparatus includes a detector configured to comprise a pair of cores encircled by probe wound coils and installed in two separate positions in an adapter, and to output a muzzle velocity signal based on eddy current signals which are generated by the probe wound coils when a bullet fired from a bullet chamber passes through the adapter, a muzzle velocity calculator configured to calculate a flight speed of the fired bullet based on the muzzle velocity signal; and a transmitter configured to transmit the calculated flight speed to the bullet. The transmitted data may be used by a controller integrated in the bullet to correct the preset time of explosion. |

| A terraforming installation has a set of one or more bases to facilitate localized heating of a polar icecap in the presence of ambient flux of cosmic rays and muons. Each base includes equipment for deploying deuterium-containing particle fuel material over and onto the polar icecap, the material interacting with the ambient flux of cosmic rays and muons to generate kinetic-energy-containing products. The equipment may include any of one or more guns for projecting shells, orbital platforms releasing packages, and rovers dispersing the fuel material over designated areas of a polar ice cap. In one embodiment, a package of deuterium-containing particle fuel material is in the form of an artillery shell comprising a shell wall encasing the fuel material with a fuse and chemical explosive charge activated by the fuse to disperse the material at a targeted location and altitude. In another embodiment, local space heating units use micro-fusion reactions from disks coated with the particle fuel material to radiate thermal energy onto the icecap surface. | ||||||

| 20 | Apparatus for setting the ignition timing in projectile fuses | US118024 | 1987-11-06 | US4779533A | 1988-10-25 | Walter Winterhalter; Wolfgang Schillinger |
| In a fuse for projectiles, a timing ring is mounted rotatably around the longitudinal axis of the fuse, whereby the ignition time or the ignition delay time may be set. To resist rotation of the set timing ring, the timing ring is secured by means of a friction system comprising a friction ring with a friction nut abutting against it. By screwing-down the friction nut, a frustoconical outer surface of the friction nut bears against a frustoconical inner surface of the friction ring to increase the resistance to rotation of the friction ring and thus the timing ring. | ||||||
