Abstract: An improved inertial projectile arrangement including a subcaliber projectile penetrator which is composed of a prepenetrator portion with a nose point and a main penetrator portion. The penetrator has a large length/diameter ratio and a high density. A sabot, composed of at least two segments, encompasses a part of the prepenetrator portion. The periphery of the encompassed prepenetrator and the sabot being joined to each other by form-locking means. The sabot segments separate from the penetrator upon exiting from the muzzle of the gun barrel from which the projectile is fired. The form-locking means are at least partially formed of irregularities or unevenesses on the periphery of the encompassed prepenetrator portion and the interior periphery of the sabot. A plurality of fracture zones and a transfer frusto-conical portion are disposed on the prepenetrator. The fracture zones achieve an intended breakup of the prepenetrator upon impact.

Abstract: The present invention relates to a high-temperature slide valve, especially hot-blast slide valve, comprising a water-cooled valve casing at least partially lined with refractory material and provided with a pair of end flanges, said casing including coolant passages or channels and, preferably water-cooled, sealing strips or bars as well as a chamber positioned transversely of the longitudinal axis of the flow cross-section of the gas conduit, which chamber has guided therein a slide valve plate for closing and opening said flow cross-section, with an actuating device being removably attached to the one end of said chamber, with the present improvement comprising that the entire center portion of said valve casing enclosing said chamber for said valve plate is formed at all sides thereof with a rectangular configuration and provided with an end wall at the end face opposite the attachment side for said actuating device.
