  • Patent number: 7076249
    Abstract: Management information is determined for both non-drifting and drifting mobile radios being serviced by a cell and/or by an RNC and reported to a management system for further processing. A distribution of drifting mobile radios to non-drifting mobile radios in a particular cell (or for all cells controlled by another RNC) is determined using the number of established radio links in the cell (or cells) for both drifting and non-drifting mobile radios. The distribution along with management information detected for non-drifting mobile radios are used to estimate corresponding management information for drifting mobile radios. In this way, management information for both drifting and non-drifting mobile radios is reported to the management system using existing formats, protocols, and procedures in both the traffic and management systems.

  • Patent number: 5520970
    Abstract: A packaging laminate for a liquid-tight, configurationally stable packaging container possessing good fat resistance properties.The packaging laminate (10) has a core layer (11) of paper or paperboard and outer liquid-tight films or coatings (12 and 13) of thermoplastic, preferably polyethylene.Between the core layer (11 ) and the one outer thermoplastic film (12), there is a layer (14) of greaseproof paper which is bonded to the core layer (11) via an interjacent layer (15) of binder or sealant plastic in order to impart fat resistance to the packaging laminate.Between the core layer (11) and the second outer thermoplastic film (13), there is an aluminium foil (16) which is bonded to the core layer (11) via an interjacent layer (17) of binder or sealant plastic, whereby the packaging laminate is given excellent oxygen gas barrier properties.

  • Patent number: 4635714
    Abstract: The invention relates to a packing groove in a plate member for a heat exchanger, especially to a packing groove at the inlet and outlet portions of the plate member. The bottom of the packing groove includes according to the invention strengthening bars, which are embossed in the bottom of the packing groove and extend substantially along the groove.

  • Patent number: 4579172
    Abstract: The invention relates to a plate heat exchanger of the type provided with plates (1,1) attached in pairs sealingly to each other, between which pairs of plates in the assembled state of the heat exchanger, gaskets (6) extend in grooves (3,4) embossed in the plates. The plates (1,1) attached in pairs to each other are connected to each other in the edge areas to be connected by a sealing folding (5,7), which extends inward between the individual plates and in between the embossings facing toward each other in the two plates and forming the grooves (3).

  • Patent number: 4482089
    Abstract: The invention relates to a method of lining a connection opening for fluid in a frame plate of a plate heat exchanger. A pipe socket with a diameter corresponding to the diameter of the opening is provided with a flange and placed in the opening, and the flange abutting the undepressed area about the opening on the inside of the plate has a thickness not exceeding 1 mm. On the outside of the plate the portion of the socket projecting there is provided with a flange to abut the undepressed area about the opening on the other side of the plate.
