Abstract: A guardrail run with a rail is arranged along and substantially parallel to a roadway. The rail is made of consecutively arranged round timber sections with abutting end sections. Each round timber section includes a metal band disposed in a vertical groove extending along the bottom side. The timber sections are releasably attached to posts anchored alongside the roadway. A locking plate having a U-shape configuration with two legs connected by a web overlaps with the ends of the metal bands of two adjacent timber sections. The ends of the metal bands are received between the two legs of the locking plate, thereby coupling the metal bands with one another.

Abstract: A stirring plug for introducing gas into a mass of molten metal and a method of making the plug. The plug is of a generally frusto-conical shape having a central axis and includes plural elongated slots formed of generally smooth walls extending between the top and bottom ends of the plug and arranged in a frustum array. Each of the slots has a predetermined cross sectional area in any plane perpendicular to the central axis. The method comprises providing a member having a hollow frusto-conical shape cavity and inserting plural wax coated steel tapes or plastic tapes in a frustom array therein. The cavity is then filled with a refractory castable mix and it is allow to air set to form a frusto-conical body. That body is then heated to an elevated temperature to form a dense ceramic plug. In the case of the plastic tapes the heating of the mix causes the tapes to melt or sublime to form the slots.
