Abstract: A method to be utilized in cell reselection in a mobile communication network offers a cell reselection mechanism based on absolute priorities. The mobile terminal measures several characteristics of a radio channel. The mobile terminal is configured to determine for each of the cells if the characteristics of the radio channel meet corresponding predetermined criteria compared to the received threshold values, and in response to outcome of the comparison determining at least one radio channel for reselection of a cell. A mobile terminal and a system for implementing the method are also described.

Abstract: A composite cast tool is cast in one continuous piece, partly of steel and partly of grey iron, so that an interconnection zone is formed between the steel and the grey iron. The steel portion forms the working component of the tool, for example a cutting edge, and the grey iron portion forms the body component of the tool. The steel portion and the grey iron portion have projections or walls extending towards one another. The interconnection zone is located in the region of union between these walls and is planar.

Abstract: A method of one-piece casting of a tool with a working component of steel and a body of grey iron, and an interconnection zone therebetween is carried out in a single mold which is kept closed and unchanged during the casting. The steel is cast first from beneath and upwards, whereafter a pause is made. The casting of the grey iron is only carried out when the temperature of the steel in the intended interconnection zone has fallen to a temperature corresponding to the liquidus temperature of the steel minus approx. 30° to 150° C.

Abstract: A mould for one piece casting of a tool, which has a working component of steel and a body of grey iron has a first mould cavity section for the steel and a second mould cavity section for the grey iron, with an interconnection zone therebetween. A dividing plane between the sections is planar and horizontal and located at the interconnection zone. A duct leads from the first section to an accommodation space for possible surplus of steel. In a method for one piece casting of a tool, which has a working component of steel and a body of grey iron with an interconnection zone therebetween, the steel is cast in a first mould cavity section and the grey iron in a second mould cavity section. A dividing plane between the mould cavity sections is planar and horizontal. An accommodation space for surplus of steel is provided to permit steel to flow from the first mould cavity section at the level of the dividing plane into the accommodation space.

Abstract: A mold for casting in one piece of a tool with a working component of steel and a body of grey iron with an interconnection zone there between has a first model section corresponding to the working component and a second model section corresponding to the body. The model sections are in contact with one another along a contact plane which is horizontal and planar and which represents the interconnection zone. In a method for producing a mold for one piece casting of a tool with a working component of steel and a body of grey iron with an interconnection zone therebetween; a first model section is produced corresponding to the steel and a second model section corresponding to the grey iron. The model sections are brought into contact with one another with the contact surface horizontally aligned and with the first model section lowermost.

Abstract: The hydroforming tool of the present invention comprises a pair of upper and lower tool inserts having open axial ends and defining an elongated cavity there between when the tool inserts are forced together. The upper and/or lower tool inserts are composed of segments that are attached to the upper and a lower base plates, by bolts. Retaining elements, such as pins, are introduced into holes in the base plates and continues into cavities formed in the segmented inserts. This prevents the insert segments from moving during the forming operation. In this way the use of base blocks may be omitted. Sometimes the friction force acting between the base plate and segmented inserts, caused by the high pressure applied to the tool surfaces, is sufficient to prevent the separation of the segments, whereby the segments are kept in place without the use of retaining elements.

Abstract: The hydroforming tool of the present invention comprises a pair of upper and lower tool inserts (B) having open axial ends and defining an elongated cavity there between when said tool inserts are forced together. The upper and/or lower tool inserts are composed of segments that are attached to the upper and a lower base plates, (A), by bolts. Retaining elements, such as pins, are introduced into holes in the base plates and continues into cavities (D) formed in the segmented inserts. This prevents the insert segments from moving during the forming operation. In this way the use of base blocks may be omitted. Sometimes the friction force acting between the base plate and segmented inserts, caused by the high pressure applied to the tool surfaces, is sufficient to prevent the separation of the segments, whereby the segments are kept in place without the use of retaining elements.

Abstract: A method and device for determining abrasive forces is disclosed. In order to determine the forces, at least two removable and distinguishable layers are applied on top of each other to a substrate or base so as to cover one another. Each layer requires a predetermined abrasive force for penetrating and removing the layer by scraping. The strength or force that is required is smaller the closer to the surface the layer is positioned. When the layers are subjected to abrasive forces, parts of the applied layers are scraped off, starting from the outermost layer and further downwards into the underlying layers. In this manner, one of the layers is exposed at each point, thereby indicating the abrasive force at that point. The exposed surface of each layer may then be identified. The method and device are particularly suitable in car-crash testing in order to assess the abrasive forces arising from airbags.

Abstract: A method is described for the in vitro determination of hypersensitivity to an allergen. The method consists of adding the allergen to a sample containing basophilic leucocytes from the blood of a patient, and then measuring the amount of degranulation of the leucocytes. The allergen is added slowly and continuously, such that the threshold concentration needed to cause degranulation of sensitized leucocytes is reached sometime during the addition step and is present for a long enough period of time to allow degranulation to occur.
