Abstract: A transfer device for moving a poison rod assembly between fuel cells in a nuclear fuel storage facility coupleable to an overhead crane. The poison rod assembly has a plurality of poison rods disposed in rows. The device includes an elongated outer member, an inner member, and a gripper assembly supported by the inner member. The inner member is slidably disposed within the elongated outer member. The overhead crane is coupled to the inner member for sliding said inner member between an upper position and a lower position. An interlock assembly selectively couples the inner member and elongated outer member. Thus, moving the crane, which is coupled to the inner member either moves the inner member relative to the elongated outer member when the interlock is not engaged, or, moves both the inner member and the elongated outer member when the interlock is engaged.

Abstract: The present invention relates to a fuel assembly (1) and a method therefor. The fuel assembly is intended for a light-water cooled nuclear reactor and comprises a first and a second locking member (9a, 9b, 10), a plurality of elongated elements (3, 3a) wherein each of the lower ends of the elongated elements is provided with an end plug (3b). The end plug (3b) is arranged guided or locked in an end plate (6) which comprises at least two adjacently disposed plug holes (6b) for receiving one end plug (3b) each. The first locking member (9a, 9b) is made in an end plug (3b) and has a concave shape and the second locking member (10) is arranged slidable in a locking hole (6c) which is adapted to extend between the two adjacently disposed plug holes (6b) and opening out into these. The second locking member (10) is made with a length exceeding the length of the locking hole (6c) and has end surfaces with shapes intended for cooperation with the concave surface of the first locking member (9a, 9b).

Abstract: A nuclear reactor plant with a light water reactor comprises a containment (1) having an upper space (2) and a lower space (3). The lower space is separated from the upper space by a separating member (4) and arranged to house a cooling medium (16). Furthermore, the plant comprises a reactor vessel (9) housing a reactor core (10) and provided in the upper space (2). The separating member (4) comprises a portion (7) which is arranged to be located at such a position that the surface portion (7) facing the lower space (3) is in contact with the cooling medium (16). The reactor vessel is provided above the portion (7).

Abstract: Gun support devices and assemblies for securing a gun, such as a rifle or a shotgun, in a fixed position relative to the ground. The gun support device has an elongate channel defined by a central portion and left and right sidewalls extending laterally from the central portion. The elongate channel is shaped to receive at least a portion of a region of a gun that extends between the forearm and the trigger of the gun. The central portion generally supports the gun, while the left and the right sidewalls generally restrain longitudinal motion of the gun with respect to the gun support device. An opening extends through the central portion at a position to permit at least a portion of the trigger of the gun to extend therethrough, thereby making the trigger accessible while the gun is received in the elongate channel. The gun support device further has an attachment mechanism for attaching the gun support device to a tripod or another support structure.

Abstract: Apparatus for converting a semi-automatic weapon into a single shot weapon. In one embodiment, the lower receiver of the weapon is replaced by a lower receiver that has no magazine well. The replacement receiver contains a loading block that can be loaded through the ejection chamber of the weapon. A spring biased plunger is provided in the replacement receiver for moving the bolt catch into a holding position when the bolt is moved into a battery position. In a second embodiment of the invention a dummy magazine is permanently secured in the magazine well and contains a loading block that can be loaded with a cartridge through the ejection port of the weapon. A spring biased plunger is mounted in the dummy magazine behind the loading block that is arranged to bias the bolt catch of the weapon into a bolt retaining position when the bolt is in a battery position.

Abstract: Incandescent reflector lamps of the R and ER type having a metallic light-reflecting coating inside exhibit a pleasing soft white appearance with substantially diminished glare and filament hot spots when the forward, light-projecting portion of the lamp envelope is coated with a coating comprising a silicone containing untreated titanium dioxide particles of a relatively coarse or large size.

Abstract: An image signal interpolating circuit including a plurality of integrated circuits 31, each integrated circuit 31 including therein memories 40 to 43 for holding respective pixel data of 2.times.2 dots, operational or computational elements 44 to 47 for calculating interpolated values on the basis of respective pixel data of 2.times.2 dots, and an input/output control section 36. The plurality of integrated circuits are arrayed to calculate interpolated value between respective pixels of a pixel block of 2n.times.2m dots.
