A method pertaining to a liquid supply system which supplies liquid to a feed device () via which liquid is supplied to at least one consumption point (): Determining presence of air supplied upstream to the feed device (), and, when presence of air is found, of reducing operating power of the feed device () compared with ordinary operation. Also a computer program product containing program code (P) for a computer () for implementing the method. Also a device and a motor vehicle () which is equipped with the device.

Method pertaining to air removal from a liquid supply system and a liquid supply system

A method for cooling a dosing unit () pertaining to an SCR system for exhaust cleaning, wherein after cessation of exhaust flow, cooling a reducing agent dosing unit () by a reducing agent supplied to it. Also running a feed device to supply the coolant reducing agent at reduced power, compared with ordinary operation. A computer program product containing program code (P) for a computer () implements a method of the invention. Also an SCR system and a motor vehicle which is equipped with the SCR system are disclosed.

Method and device pertaining to cooling of dosing units of SCR systems

A method pertaining to an SCR system for exhaust cleaning, includes deciding about a need, after cessation of an exhaust flow, to cool a reducing agent dosing unit () by a reducing agent supplied to it, and includes predicting a temperature pattern of the dosing unit () as a basis for deciding about the need and predicting whether a predetermined temperature of the dosing unit will be reached after cessation of exhaust flow. Also a computer program product containing program code (P) for implementing the method, an SCR system and a motor vehicle which is equipped with the SCR system are disclosed.

A method pertaining to an SCR system in which reducing agent in liquid form is supplied to a feed device () and via which feed device reducing agent is supplied to at least one consumption point () from a container (): the steps of continuously detecting the feed pressure (P) which the feed device () furnishes, and controlling the operation of the feed device () on the basis of changes (P') in the feed pressure (P), with the object of reducing the impact of unwanted air supply at the feed device (). Also pertaining to a computer program product containing program code (P) for a computer () for implementing a method according to the invention. Also an SCR system and a motor vehicle which is equipped with the SCR system are disclosed.

Method pertaining to air removal from a dosing system at an SCR system and a SCR system

Filing gauge for saw chains

A device for locating a desired information track on an information carrier, after an information transducer has been passed over the information tracks on the carrier in the transverse direction in response to a starting pulse, which utilizes a control signal that is derived from the alternating voltage thus obtained, to keep the relative velocity of the transducer relative to the information tracks constant.

Device for locating a desired information track

A device at an unfoldable escape-ladder, which is assembled of rungs (1), the ends (3) of which are attached between flexible lateral members (5), preferably steel wires, which rungs (1) are longish and made of plate-shaped material and can be stacked, the upper portion of the escape-ladder intended to be attached to a wall (6), a stay or the like, which escape ladder in folded state has the rungs (1) lying stacked and forming with each of the steel wires (5) a ring for each rung (1), which escape-ladder is provided with a means for releasing the ladder. According to the invention, two steel wires (4) or rods are provided which are located in parallel and rigidly mounted along the direction, which the ladder in unfolded state is desired to assume, which steel wires (4) or rods extend through the rings formed by the first-mentioned steel wires (5). As a result thereof, the last-mentioned steel wires (4) or rods in unfolded state of the ladder are wound about the first-mentioned steel wires (5) and thereby render the ladder extremely steady.

Device at unfoldable escape-ladder

A device at an unfoldable escape-ladder assembled of rungs (1), the ends of which are attached between flexible lateral members (2), preferably steel wires, said rungs (1) being longish and of plate-shaped material and capable to be stacked, the upper portion of the escape-ladder intended to be attached to a wall (4), a stay or the like, which escape-ladder in folded state having its rungs (1) lying stacked and each of the steel wires (2) forming a ring for each rung (1), which escape ladder is provided with a means for releasing the ladder. According to the invention, each rung (1 ) has substantially S-shaped cross-section, where the free ends of the S-shaped portion (7) are extended so as to form two parallel legs (8,9), and that the steel wires (2) are attached on the rungs (1) with their substantial longitudinal direction perpendicular to said legs. In unfolded state of the ladder and upper one (8) of said legs constitutes a tread and the lower one (9) constitutes a distance member for maintaining the ladder at a certain distance from a wall or the like, along which the ladder is unfolded.
