Abstract: The present disclosure relates to a hydraulic mining shovel. The shovel may comprise a main frame, a power module and a counterweight module. The shovel may further comprise a first exhaust aftertreatment module and a second exhaust aftertreatment module, each being mounted onto the counterweight module and each including a reductant tank and pump unit and a selective catalytic reduction unit. The first exhaust aftertreatment module and the second exhaust aftertreatment module may be configured and arranged substantially mirror-symmetrically at opposing sides of the counterweight module with respect to a central longitudinal axis of the main frame.

Abstract: The invention relates to a rail attachment system (1) for attaching a rail (2) to a concrete support slab (3a) or a concrete sleeper (3b) or to a steel structure comprising an intermediate plate (4), a rail attachment plate (5) with angle guide plates (6, 6b) arranged thereon, at least two first tensioning clamps (7a) for clamping the rail foot (2a) to the rail attachment plate (5) as well as screws (9) and/or ankle bolts (10) and at least two second tensioning clamps for screwing the rail attachment system (1) to the underlying surface, characterized in that an elastic intermediate layer (8) is arranged between the rail (2) and the rail attachment plate (5), and the intermediate plate (4) is composed of a highly elastic material and/or comprises a steel plate (4), at least two second tensioning clamps (7b) for clamping the rail attachment plate (5) to the substructure, preferably via the intermediate plate (4), wherein the first and second tensioning clamps (7a, 7b) are embodied in a highly elastic fashion w

Abstract: Rail-fastening system for the non-positive resilient fastening of a rail (2) on a sleeper (1) of a railway track installation, comprising at least one angle guide plate (5), which can be fixed to the sleeper (1) with at least one screw (4), and at least one clamp (3), characterized in that the bending radii of the clamp arms (3a, 3b) of the clamp (3) preferably lie in the range from 18-70 mm, wherein the ratio of mutually adjacent bending radii within each clamping arm is ?1.9 and the ratio of the greatest to the smallest bending radius thereof is ?3.8, and in that the ratio of weight to width of the angle guide plate is <1.3 g/mm, preferably about 1.25 g/mm.

Abstract: A method and apparatus for accumulation of hyperpolarized .sup.129 Xe is disclosed. The method and apparatus of the invention enable the continuous or episodic accumulation of flowing hyperpolarized .sup.129 Xe in frozen form. The method also permits the accumulation of hyperpolarized .sup.129 Xe to the substantial exclusion of other gases, thereby enabling the purification of hyperpolarized .sup.129 Xe. The invention further includes .sup.129 Xe accumulation means which is integrated with .sup.129 Xe hyperpolarization means in a continuous or pulsed flow arrangement. The method and apparatus enable large scale production, storage, and usage of hyperpolarized .sup.129 Xe for numerous purposes, including imaging of human and animal subjects through magnetic resonance imaging (MRI) techniques.

Abstract: A method and apparatus for hyperpolarization of flowing noble gases is disclosed, including means for hyperpolarization of noble gases in a continuous flow arrangement. Noble gases such as xenon-129 and helium-3 can be hyperpolarized using the disclosed method and apparatus. Preferably, the noble gas is hyperpolarized via spin exchange between atoms of the noble gas and an alkali metal such as rubidium. Also, a method and apparatus for accumulation and/or storage of hyperpolarized noble gases in a continuous flow arrangement is provided. The method and apparatus enable large scale production, storage, and usage of hyperpolarized noble gases for numerous purposes, including imaging of human and animal subjects through magnetic resonance imaging (MRI) techniques.
