Abstract: The diameter of a segment of a peripheral rod in a fuel assembly is measured between two successive spacer grids. A measuring tool is positioned at a level situated between the two successive spacer grids, the tool comprising two measuring fingers that are free to move relative to each other in a first horizontal direction and that are urged towards each other by a resilient return arrangement, and that extend in a second horizontal direction perpendicular to the first horizontal direction. The measuring fingers are moved in the second horizontal direction towards a rod so as to put two contact pieces of the measuring fingers into contact with two zones of the rod segment. The measuring fingers are moved in the vertical axial direction of the rod along its segment situated between the two spacer grids and an electromagnetic sensor is used to measure the distance between the measuring fingers in the first horizontal direction while the measuring fingers are being moved axially.

Abstract: A connecting device for a weapon accessory has a seat having a sliding rack that removably connects the longitudinal groove of a weapon, and one or more gripping blocks disposed adjacent corresponding side walls of the seat. The gripping block assumes a first position where the gripping block extends inwardly towards the sliding rack to engage a selected transverse groove of the weapon, and a second position where the gripping block extends outwardly away from the respective side wall of the seat to release the longitudinal groove of the weapon. The connecting device also includes a control mechanism operatively coupled to the gripping block. The control mechanism assumes a normal position with the control mechanism controlling the gripping block to maintain the gripping block in the first position, and actuation of the control mechanism causes the gripping block to assume the second position.

Abstract: The present invention is a modular stock system for rifles. The system replaces the rifle's buffer tube with a modified one containing a mount for a constant cheek weld and a rail track for adjustment. A stock module then mounts on the replacement buffer tube. The stock module is interchangeable depending on the user's needs. Various configurations of the stock module are discussed, including adjustable stocks, fixed stocks, and specialized stocks. The stock module may be made even further modular by the addition of rail system.

Abstract: An L-shaped tube has a horizontal member that fits into a trailer hitch, and a vertical member. A platform is secured to a post that fits into the vertical member. The platform has bolt holes arranged to engage a variety of commercial clay target throwers and a gun/pistol rest. A threaded dowel is inserted through the a 180 degree horizontal slot in the vertical member, and screwed into a threaded hole in the post, thereby limiting the range the platform post can swivel within the vertical member. The dowel can be tightened to lock the post between zero and one-hundred-eighty degrees. A tension cable secures the vertical member to the vehicle to attenuate vibrations. A gun/pistol rest configured to mount from the platform has a forward cradle for a gun stock or barrel, and rear mount that variously functions as a rifle-butt cradle or a pistol-butt support.

Abstract: The firearm device for disabling a firearm for dry fire practice. A bushing is inserted in the firearm having a diameter of a cartridge. The bushing includes a through bore which receives a length of flexible material. One end of the flexible material is enlarged, so that is stops when it is pulled against the surface of the bushing. The length of flexible material extends through the barrel and is visible to users of the device. The length of the bushing and enlarged end of the flexible material is established so that the rear surface of the enlarged end is positioned to be struck by the firearm firing pin when the hammer is released. The device prevent and round from accidentally being introduced into the chamber, as well as indicates to users that the device has been safely rendered inoperative for dry fire practice.

Abstract: The method involves measuring hydrogen permeation in the tubes by mass spectrometry, wherein the tube is inserted into a high or ultrahigh vacuum device in which a mass spectrometer and a total pressure gauge are located. H2 or H2 and inert gas mixtures are circulated inside the tube at the required partial pressure. The tube is then heated and the appearance of H2 outside the tube is observed. The flow thereof inside the tube and emergence time, called permeation time, are determined based on permeation curves. The emergence time of the first microcrack is also determined.
