Abstract:
A weapons system with at least one fire control device and a launcher uses a remotely fragmentable projectile for defense against a missile or other movable target. Although the probability of a hit is increased with the use of a remotely fragmentable projectile, the system of the invention increases the success of the defense, which is nevertheless questionable because of the low density of the projectile fragments. The method utilizes a projectile, the fragments of which are concentrated in a ring, which spreads out in the shape of a conical envelope. The projectile is individualized at launch. Tracking of the target continues during the flight of the projectile, because of which the expected location at the pre-calculated time of impact becomes continuously better known. The fragmentation command is transmitted to the projectile as late as possible. It is always possible with a high degree of probability to score a hit. An increased chance of success of the defense is the result of the relatively great density of the fragments concentrated in the ring.
Abstract:
The improved bowling ball tool kit includes a tool having an elongated shaft with an expanded handle on one end and one of a number of bowling ball finger hole scrapers of differing diameters supplied by the kit. The scrapers are separately releasably attachable to the opposite end of the shaft of the tool. The scrapers are preferably formed of silicon carbide or another hard material which will readily ream, slice or abrade the plastic of a bowling ball to enlarge its finger holes. The kit also includes a connector, preferably in the form of a threaded connector bolt to releasably hold the scrapers in place by threading into the shaft end after passing through a central hole in the scraper. Each of the scrapers is frusto-conical disc and is mountable on the shaft end so that the sides of the disc taper down and away from the shaft. The tool and kit are simple, durable, small, portable, inexpensive and efficient to enlarge bowling ball finger holes so as to accommodate fingers with gradually increase in diameter as bowling is practiced.
