Title: Improvements Relating to Gun Sights
IPC: F41G1/393
Filed: 1980-11-06
Abstract: On the body 7 of a tank are mounted a gun 5 which pivots about axis 1 and a sight 8 which pivots about an axis 2. To ensure that the sight 8 is aligned with the gun 5 for all angles of elevation the sight 8 and gun 5 are joined by a link 13. Adjustments must be made to ensure that the axes 1, 2, 3 and 4 lie at the corners of a parallelogram. This is done by setting the gun at midrange and adjusting turnbuckle 13A until the sight is aligned with it. The gun is then lowered to a given elevation and the error in the elevation of the sight is noted. The gun is then raised to another elevation and the error in the elevation of the sight again noted. From the two error values the adjustment required to the distance between axes 2 and 3 and the distance between axes 3 and 4 can be calculated. A special adjusting mechanism (Fig. 2: not shown) is used to carry out these adjustments, and moves the axis 3 in two orthogonal directions. <IMAGE>

Title: Method of making molds
Inventor: UZAKI NAGATO
IPC: B22C9/12
Filed: 1982-04-29
Abstract: Molding sand (9) containing a predetermined amount of water, e.g. 2-5 weight % water, is charged into a metal mold box (2). The inner surfaces of the mold box are cooled by refrigerant, preferably prior to charging the box with the sand, to a temperature in the region of -10 DEG C to -50 DEG C.

The mold is then removed from the mold box and the entire mold is frozen and hardened by cooling with refrigerant. Alternatively, the sand may be charged into a pattern plate and molding flask assembly. Either the pattern plate only is cooled in which case the pattern plate is removed after the surface in contact with the mold has frozen and hardened and before the entire mold whilst accommodated in the molding flask is frozen and hardened by cooling, or the pattern plate and molding flask are both cooled in which case the pattern plate is removed and the mold is stripped from the molding flask before the entire mold is frozen and hardened by cooling. <IMAGE>
