Abstract: The invention concerns a halogen-free polymeric blend capable of ionic conductivity comprising either one or more polyether-based polymers or copolymers that have favorable structures to facilitate polymer chain segmental motion and ion hopping environment, selected from the group of polyether-block-polymers and polyether-based polyurethanes, or said polyether based polymers or copolymers together with one or more ionomers formed by neutralization of ethylene acid co-polymers, as well as one or more specific halogen-free ionic complexes or salts comprising a weakly coordinating anion and a cation of an alkali metal or alkaline earth metal. Further, the invention concerns the use of said blend and a plastic material containing said blend as an additive.

Abstract: The present invention relates to an elevator and a method for measuring the load in an elevator, in which the elevator car is suspended on hoisting ropes with at least one upward-directed diverting pulley or diverting pulley pair, from which the elevator ropes go upwards on both sides, and at least one downward-directed diverting pulley or diverting pulley pair, from which the elevator ropes go downwards on both sides. In the elevator at least one upward-directed diverting pulley or diverting pulley pair and at least one downward-directed diverting pulley or diverting pulley pair is fixed to the elevator car with a shared supporting structure. In the method the tension information is measured from a supporting structure and a load-weighing signal is formed using the tension information obtained.

Abstract: The invention relates to distribution of IP traffic between more than one route between a node and an IP network. The invention is concerned with a new method for distribution of connections between a plurality of possible routes for transmission of IP packet traffic between a source node and end nodes, each of the routes being associated with a plurality of IP addresse. According to the invention, a route is selected for a new connection to be established between the source node and an end node for transmission of packet traffic, the selected route is taken into use by translating source IP addresses of packets transmitted from the source node to said end node to an IP address associated with the selected route, and said selection of a route is performed on the basis of predefined criteria. Preferably, the selection of the route is performed on the basis of round trip times measured by a new method using packet replication.

Abstract: A device for moving a pig through a conduit, such as a pipeline, is proposed, comprising at least one pulling element with at least one sealing means. The sealing means comprises a supporting structure with variable circumference with at least one sealing element disposed on the circumference of the supporting structure. In a preferred embodiment, the supporting structure comprises supporting arms disposed substantially radially and being pivotable about axes, each perpendicular to the longitudinal central axis of the pulling element, and is mounted to the pulling element via the supporting structure and a central sleeve which can be fixed to the pulling element.

Abstract: A device (1) for passing through pipes in the form of a pig (1) moving through the pipe and guided on the inner wall thereof has at least one pig body (16) and support elements (8a) on the outer periphery thereof for guidance within the pipe as well as drive elements (10a, 10b) in the form of collars for transport in the pipe. The device is distinguished by improved entrance into the pipe conduit in that at least one of the collars (10a, 10b) can be radially expanded.

Abstract: In order to facilitate introduction of an inspection pig through an introductory conduit having a smaller diameter and into a pipeline of large diameter and transporting a fluid, in particular gas or oil, the invention proposes a device for inspection of pipes having sensors disposed about an outer periphery thereof having radially expandable inspection units (6, 7), wherein, in particular, a front and a rear inspection unit (6, 7) having sensors (15; 15′) displaced with respect to each other in a peripheral sense can be moved axially towards each other.
