Title: High firing rate,light gas hypervelocity gun and ammunition therefor
IPC: F41F1/00
Filed: 1968-08-31
Abstract: A hypervelocity gun for firing primary ammunition rounds 32 each containing a propellant 38 and a piston 36 and secondary ammunition rounds 40 each containing only a projectile, comprises a barrel 12 having a bore 14 and breech means, e.g. two breech mechanisms 16, 18, for transporting the primary rounds 32 in succession to a primary firing position at the breech end of the barrel 12 and the secondary ammunition rounds 40 in succession to a secondary firing position forwardly of the breech end of the barrel, the rounds 32, 40 in their respective firing positions being co-axial with the bore of the barrel. A pressurizing means, e.g. a pressure vessel 68, is provided for introducing gas under pressure into the bore 14 between the firing positions. When the gun is loaded the projectile 44 of the secondary ammunition round is yieldably restrained by a sleeve 46 which abuts the barrel at the forward end of the secondary breech mechanism 18 so that, on firing of the primary ammunition round 32 by an electrical firing means 50, the gas introduced between the firing positions is further compressed by passage of the piston 36 through the bore of the barrel until the projectile is squeezed through the bore of the sleeve 46 to be urged outwardly of the barrel, the piston being then retained in the secondary firing position. Although the weapon may have any kind of primary and secondary breech mechanisms, i.e. that is both the same kind or they may be different, the breech mechanisms 16, 18 shown are rotatable cylinders having open chambers, the open chambers passing through infeed, firing and ejection stations. The chambers are fed from hoppers (Fig. 1, not shown) and the cylinders are driven by a motor 58 through a Geneva mechanism so that the chambers are halted in their stations (Fig. 5, not shown). Cam operated switches control the gas release into the bore of the barrel and the firing of the primary ammunition round (Fig. 5). The gun shown has a single, fixed barrel, but a group of rotatable barrels may be used. Different ammunition as disclosed in Specifications 1,247,871 and 1,247,872 may be used as the primary ammunition.

Title: Method and apparatus for a nuclear reactor for increasing reliability to scram control elements
IPC: G21C19/105
Filed: 1975-05-19
Abstract: A method and apparatus for increasing the reliability of linear drive devices of a nuclear reactor to scram the control elements held in a raised position thereby. Each of the plurality of linear drive devices includes a first type of holding means associated with the drive means of the linear drive device and a second type of holding means distinct and operatively dissimilar from the first type. The system of linear drive devices having both types of holding means are operated in such a manner that the control elements of a portion of the linear drive devices are only held in a raised position by the first holding means and the control elements of the remaining portion of linear drive devices are held in a raised position by only the second type of holding means. Since the two types of holding means are distinct from one another and are operatively dissimilar, the probability of failure of both systems to scram as a result of common mode failure will be minimized. Means may be provided to positively detect disengagement of the first type of holding means and engagement of the second type of holding means for those linear drive devices being operative to hold the control elements in a raised position with the second type of holding means.

Title: Semi-automatic gun
IPC: F41A5/00
Filed: 1976-10-29
Abstract: A semi-automatic gun having a gas operated device for actuating a reloading mechanism thereof. The reloading mechanism includes a cartridge magazine which extends parallel to the gun and the actuating device includes an annular piston sliding over the cartridge magazine in an annular chamber defined between the cartridge magazine and a cylinder, closed at one end, which surrounds a portion of the cartridge magazine. Gas transfer ducts convey gas from the interior of the barrel of the gun, through the wall of the cylinder into the annular chamber defined thereby. The annular piston has a peripheral groove therein at a position adjacent the gas transfer ducts so that gas entering the annular chamber impinges on the piston and not on the wall of the cartridge magazine subsequently these gases transfer to a lower chamber between the end of the piston and the closed end of the annular chamber along a passage between the piston and the wall of the chamber itself.

Patent ES-472630-A1 (ES)
Title: Dummy bar head for continuous casting and method of starting a continuously cast strand
IPC: B22D11/08
Filed: 1978-07-27
Abstract: A dummy or starter bar for starting a strand in a continuous casting installation having an open-ended mold is provided with a head which is receivable in the mold. The dummy bar head has a peripheral surface which faces the inner surface of the mold. The dummy bar head further has an end face at least part of which is inclined with respect to the peripheral surface. The end face is directed towards the inlet end of the mold. The dummy bar head is provided with a dovetail-like recess which opens to the inclined part of the end face. The recess enables the strand to become coupled to the dummy bar head and is arranged so that coupling occurs in a manner which permits the strand and the dummy bar head to become detached by relative movement thereof in a direction transverse to the longitudinal axis of the strand. The recess is bounded so as to prevent penetration thereof into the peripheral surface of the dummy bar head and this, in conjunction with the inclination provided for the end face of the dummy bar head, enables the dummy bar head to be readily sealed in the mold. A method of starting the strand involves placing bars of chill material in the recess in such a manner that they are inclined with respect to the inner surface of the mold and that the ends thereof are located in the undercut section of the recess. The molten material introduced into the recess solidifies about the chill bars. The latter serve as an anchor within the solidifying mass thus providing an enhanced connection between the dummy bar head and the strand in the first few critical moments of withdrawal of the strand from the mold.

Title: Process for bonding workpieces of aluminium-base alloys and steel.
IPC: B23K20/00
Filed: 1978-12-06
Abstract: The invention concerns a process for assembling aluminum-based members and steel members.
