Abstract: A housing for a device mountable on a mounting surface has a housing element provided with two mounting flanges each having a passage adapted to extend substantially perpendicularly to the mounting surface and formed to receive a mounting bolt, two bushings extending through the mounting flanges and surrounding the passages, the bushings being composed of metal and injection molded with a material of the housing element, each of the passages being formed as an elongated hole with a width adapted to correspond to a diameter of the bolts, the bushings corresponding to a contour of the passages and surrounding the passages with a radial distance therefrom, the bushings being provided with peripheral formations which are filled with the material of the housing element, and the bushings at an inner peripheral side being free from the material of the housing over a part of an axial length of the bushings and a lower side of the mounting flanges.

Abstract: A tubular fitting of sheet metal is formed in one piece of a container, for example, a bung container and an internally threaded bushing is press fitted into tubular fitting or is held therein by formations, texturing and/or adhesive and is braced axially against a bead formed on the free end of the tubular fitting.

Abstract: The present invention includes a system for storing and transporting a liquid in which a series of tank cars each have a hollow tank body with an inlet and an outlet supported on a frame with a plurality of wheels on the frame. In one embodiment, these cars are connected together with a sealable male fitting and female fitting which interengage to allow fluid flow between the cars. Using this valve arrangement, a series of cars hooked together may be filled from a single fill point or station. A method of storing and transporting a liquid involving these storage cars is also disclosed.

Abstract: An improved plugging system for plugging chamfered flow ports of small diameters in the core barrel of a pressurized water nuclear reactor is disclosed herein. The system is comprised of improved core barrel plugs that are telescopically contractible to facilitate installation, as well as a handling tool having a compact hydraulic ram and plug-holding cradle that is easily manipulable in the limited access space between the core barrel and thermal shield of the reactor for inserting and expanding the plugs into sealing engagement with the core barrel flow ports. The plugs of the system are formed from a generally cylindrical plug body that is radially expandible, and a retaining ring that is telescopically engaged around the plug body which allows it to be slid toward the middle of the plug prior to installation in order to minimize the overall length of the plug prior to the insertion operation.
