  • Patent number: 6627007
    Abstract: A method has been developed for surface modifications of high temperature resistant alloys, such as FeCrAl alloys, in order to increase their resistance to corrosion at high temperatures. Coating it with a Ca-containing compound before heat-treating builds a continuos uniform and adherent layer on the surface of the alloy, that the aluminum depletion of the FeCrAl alloy is reduced under cyclic thermal stress. By this surface modification the resistance to high temperature corrosion of the FeCrAl alloy and its lifetime are significantly increased.

  • Publication number: 20030127446
    Abstract: The present invention is for a method for heating of blanks and other heating of metallic materials in a furnace before working where heat is transferred to a blank in the furnace by radiation. According to the method of the invention an important part of the radiation hits the walls of the furnace and are reflected there before it is transferred to the blank. Preferably the furnace is designed so that heat radiation is reflected also at the bottom of the furnace. At least 50% of the radiation which reaches the blank ought to be reflected radiation. The invention is also for a furnace for beating of blanks and other comprising at least one furnace bottom part (1) and at least one furnace top part (4) having side walls (5, 6, 7, 8) where at least parts of the side walls of the top parts are inclined so that opposite walls are inclined towards each other.

  • Publication number: 20030054819
    Abstract: Apparatus and methods for managing the operation of wireless communication systems are described for transferring inter-exchange information. Interdepending data pertaining to inter-exchange traffic handling events is transferred from the exchange where the data was entered in man-machine-language (MML) by a human operator to other applicable exchanges where the data is automatically entered base upon a subscription between the serving exchange and the target exchange.

  • Publication number: 20030046256
    Abstract: A system for information management comprises a look-up unit (4), in which are stored particulars about a plurality of regions (5′), each of which represents an area on at least one imaginary surface (5) and is allocated an address. A user unit (2) records electronically information which comprises one or more positions on the imaginary surface (5) and sends all or parts of the recorded information to the look-up unit (4). When the look-up unit (4) receives the recorded information, it identifies, based on the position content of the recorded information, a region (5′) on the imaginary surface (5) and sends the address which is allocated to the identified region to the user unit (2).

  • Patent number: 6506596
    Abstract: The present invention relates to a method of of transferring genomic DNA from apoptotic bodies to engulfing cells, wherein DNA is transferred from a donor cell to a recipient cell. More specifically the method includes providing somatic donor cells comprising desired DNA; generating apoptotic bodies of said donor cells; incubation of the apoptotic bodies with engulfing recipient cells under biological conditions allowing uptake of DNA from the apoptotic bodies by said recipient cells; and optionally selecting recipient cells which have integrated DNA from the apoptotic bodies. The present method is useful in various pharmaceutical applications, such as in vaccine preparations and gene identification procedures.

  • Publication number: 20020053596
    Abstract: A business card and a pen, which is adapted to detect a position-coding pattern on the business card and calculate a coordinate by means of the pattern. When activating a send box by means of the pen, a computer sends a .vcf file containing the card holder's particulars to a card recipient belonging to the pen holder. When using an optional pen, the .vcf file is sent to a recipient indicated on the keypad of a mobile phone or written on the business card in associated fields or marked in other manners. The pen communicates with a computer wirelessly, for instance via Bluetooth, mobile phone and the Internet. Additional information can be drawn on the back of the business card and be attached to the transmission, such as date and time for the next meeting, a small drawing or sketch etc.
