Abstract: There is provided a method for detecting failure of a gas-hydraulic damper for a rail vehicle, comprising: - receiving a first input signal (S1) indicative of a stroke related parameter of the gas-hydraulic damper determined at a first time instance, - determining a first stroke value, based on the first input signal (S1), - receiving, at least one second input signal (Si), wherein each subsequent signal (Si) is indicative of a respective stroke related parameter measured at a respective subsequent time instance, - determining a respective stroke value based on each of the second input signals (Si), - determining a stroke value over time based on the determined stroke values, and - determining that there is a failure of the gas-hydraulic damper if the stroke value over time, fulfils a first criterion. Also provided are a system, a gas-hydraulic damper and computer program product.

Abstract: The present invention relates to a damper for a rail vehicle, the damper comprising —a cylindrical housing (1) wherein a hollow piston (2) is received axially movable, —a working chamber (5) of variable volume in the housing, —a overflow chamber (4) of variable volume in the piston, the hydraulic overflow chamber (5) being connected to the hydraulic working chamber (5) via a throttle (8) that is in a flow passage between the working chamber (5) and the overflow chamber (4), —a spring chamber (3) of variable volume in the piston, the spring chamber (3) being configured to hold a gas volume for acting as a spring, and the spring chamber being separated from the hydraulic overflow chamber (4) by a separator piston (6) that is axially movable, and the damper further comprising a pressure detector (7) that is configured to detect a pressure in at least one of the spring chamber (3), the working chamber (5) and the overflow chamber (4).

Abstract: Compounds of formula (I) wherein R1, R3, R4, R5, R6, R7, and R10 are as defined in the specification, are described. The present invention also relates to pharmaceutical composition comprising said compounds and to the use of said compounds in therapy. The present invention further relates to processes for the preparation of said compounds and to new intermediates useful in the preparation thereof. Beside, the invention relates to salts and polymorphic forms of the new compounds as well as the preparation thereof.

Abstract: To measure the cross-section of an object in a contact-free manner (that is to say without contacting the object) use is made of an optical sensor system and means for causing relative movement of the sensor system and the object being measured, the sensor system comprising at least two emitters which emit respective scanning rays at an angle to one another and directed to respective receivers which supply signals to an evaluation unit upon interruption of each ray by the object and subsequent cessation of said interruption; at least two of said co-operating emitter-receiver pairs are so arranged that their scanning rays (or projections thereof on a common plane parallel to the scanning rays) cross one another and extend at angles to the direction of relative movement.

Abstract: A filter disc for a magnetic separator is formed of two wall discs having a layer of permanent magnets arranged between them and in contact with each other. The permanent magnets have holes therethrough and have cut-away corners. The magnets are adhered to the wall discs by glue which enters the openings between and within the permanent magnets.
