Abstract: A foldable feed rail for a rock drill is composed of two segments, a first beam defining a first rail segment and a second beam defining a second rail segment. The second beam may be pivotally connected to the first beam with a hinge to enable the second beam to be folded relative to the first beam. Alternatively, the second beam can be detachably connected to the first beam so that the second beam can be removed altogether from the first beam. This invention enables the feed rail to be shortened, thereby making the feed rail much easier to manoeuvre in mines.

Abstract: A mink/fox transportation system (2) for individual transport in connection with the production of mink/fox furs, for example, the transport of upright-standing expansion pelt boards (4), with or without tanned, or tanned and dried pelts, to one or more relevant receiving stations (170, 172), has at least one, preferably a plurality, of self-driven traction units/carriages (10) driven along a predetermined transport path in the form of a track (6) which is formed of track elements (8,8?,8?,8??) that have been assembled together configured to the arrangement of the particular production facility. The traction units/carriages (10) have a housing (12) with an upwardly-facing side (20) in which an opening (14) is formed for receiving a blunt part (18) extending from the foot end (16) of the pelt board, or surrounds a smaller part of the whole of the foot end of a pelt board.

Abstract: A flexible track system includes at least one track section that includes a main body comprising two opposed side portions and a running surface extending between the two opposed side portions. The two opposed side portions extend at an angle from the running surface. Grooves are formed within the main body to allow flexion of the main body. One or more sets of a plurality of members are formed on, protrude from, and extend in a lengthwise direction along the main body. A constraining section engages a corresponding set of the members. End stops may secure the constraining sections to the main body of the track section. Force is applied to the track section to achieve a desired form or position. The grooves expand or contract in accordance with the applied force, and the constraining sections conform to and retain the applied position even after removal of the force.

Abstract: Provided is a grooved rail for rail vehicles having flanged wheels, the grooved rail including a rail head provided with a running rail, a flange groove, and a counterrail, in addition to a rail web, a rail base, and lateral rail chambers extending between the rail head and the rail base. The running rail includes an asymmetrically-arranged vehicle-guiding flange, extending towards the flange groove, the asymmetrically-arranged flange formed in such a way that the width part of the rail base, on the side of the running rail, is larger than the width part on the side of the counterrail by a factor of at least 1.2. When the depth of the flange groove is >20 mm, the flange has a flange inclination of >78° with respect to an essentially horizontal axis of the rail web.

Abstract: A magnetized rail for improving the adhesion between the rail and the steel wheels of a rail car will help prevent skidding of the rail car when decelerating from a high speed. The rail is split with an air gap in the rail head and a electromagnet coupled between the split webs of the rail.
