  • [专利] Piston-cylinder device and method for detecting axial position
    (NO20150912) The invention relates to a fluid media driven piston-cylinder device comprising a first assembly including a cylindrical barrel (22) with a front end cover (1 ) and a rear end cover (2), a second assembly including a piston (3) guided by the barrel (22) and a piston rod (4) fixed to the piston (3) and extending in an axial direction out through an opening (12) in the front end cover (1 ), and a contact arrangement providing an electrical contact between the first and second assembly. The contact arrangement comprises a electrical conductor device (5) having a variable length in the axial direction and being located within the cylindrical barrel (22), a rear contact surface (7) associated with the second assembly and arranged for establishing an electrical contact with a rear end portion of the electrical conductor device (5), and a front contact surface (6) associated with the first assembly for establishing an electrical contact with a front end portion of the electrical conductor device (5). The invention also pertains to a method for detecting an axial position of a piston of a fluid media driven piston-cylinder device relative to an at least partly electrically conducting external object. Using the invention, a contact arrangement including a spring loaded mechanism that slides along a piston rod surface in the piston-cylinder device can be avoided in crust breaker systems, which system comprises the piston-cylinder device and a smelting pot. In this way, the electrical conductor device is not subjected to wear, high friction and contamination. (From WO2014092635 A1)

The filter is preferably a diesel particulate filter like the ones used in automobiles and vans, i.e. a filter for trapping ash or soot carried by the exhaust gases of diesel internal combustion engines, comprising aluminium, magnesium, zinc and/or cadmium. Cleaning is effected after removing the filter from the vehicle, e.g. in a workshop or garage, by immersing it in the detergent solution, preferably for 10-14 hours at a temperature between 15 and 30oC.
