    摘要： A refractory brick wall system for towers and the like which includes an outside casing and a plurality of bricks laid up in a pattern on the inside of the casing. Tie-back devices secure the bricks to the casing and allow for relative horizontal and relative vertical movement between the bricks and the casing. A plurality of shelves are fixed to the inside of the casing at vertically spaced intervals to provide support for the bricks in vertical sections thereof. A lightweight, insulating refractory material is cast between the casing and the bricks. The bricks themselves are shaped with ring and groove sides for interlocking of the bricks in a laid-up wall construction thereof.

    摘要： A firearm (10) constructed in accordance with the principles of a preferred embodiment of the present invention and configured for firing large caliber ammunition at precisely defined targets at long range is disclosed. The firearm (10) broadly includes a stock (12), a receiver (14) supported in the stock (12), a barrel (14a) threadably coupled to the receiver (14), hardware (16) associated with the receiver (14) for firing ammunition through the barrel (14a), a scope (18), and a scope-mounting base (20) coupled to the receiver (14) for mounting the scope (18) thereto in the line of sight. The base (20) includes a mount (24) adapted to be fixed to the receiver (14), an adjustable recoil lug (26) for anchoring the base (20) relative to the receiver (14), and a pair of ring clamps (28 and 30) for coupling the scope (18) to the base (20). The adjustable recoil lug (26) prevents undesired movement of the base (20) relative to the firearm (10) when the firearm (10) is fired and enables the lug (26) to be used on virtually any base with any firearm having an ejection port without the need to specially manufacture the lug (26) for the particular firearm. In a preferred embodiment, the mount (24) includes a recessed groove (44) operable to receive epoxy that enables a secure and level mounting on virtually any type of firearm. In the preferred embodiment, the improved ring clamps (28,30) include arcuate engagement surfaces (88, 90, 92) that enable a consistently uniform and optimized torque applied between the ring clamps (28,30) and the mount (24). An alternative embodiment is also disclosed wherein the firearm (200) includes a recoil-reduction device (202) and the scope-mounting base (204) includes both front and rear adjustable recoil lugs (206, 208).
