  • Patent number: 10954579
    Abstract: The present invention relates to a method, and system for performing such method, for producing a press hardened part (2?) of heat treatable material having zones of different structure by partially heating a blank (2) before the blank is processed. The method (100) comprises the steps of arranging (104) the blank in a furnace (10) for heating the blank to a temperature equal to or above the austenitization temperature of the material of the blank to get the blank into an austenitic phase, in a IR heating station (10) partially heating (106), by means of IR radiation (24), at least one first zone (2a) of the blank thereby keeping the at least one first zone of the blank in the austenitic phase, and arranging (108) the blank in a processing unit (30) for forming and quenching the blank to a press hardened part.

  • Patent number: 7957376
    Abstract: The present invention relates to a method, signal and devices for facilitating distribution of multimedia broadcast multicast services, i.e. MBMS, in a telecommunications network by receiving an MBSM session start message from a broadcast/multicast service center; sending control traffic on a control network; sending as control traffic to a serving node an MBMS session start request message and including a common tunnel end-point identifier, i.e. common TEID, in the MBMS session start request message; receiving information from the serving node indicating the acceptance of using IP multicast; and sending media content on an IP multicast backbone to hosts that have joined the multicast group using the common TEID. If any part of the communication network does not accept the IP multicast backbone as distribution method tunnels will be used between the gateway and serving node and between the serving node and control node.

  • Patent number: 5634747
    Abstract: A spiral drill and a method to manufacture a spiral drill with two indexable inserts at different distances from the center line and two coolant channels, where the coolant channels (23,24) run parallel to the center line within the shank part, and where the spiral part has been twisted while heated to form spirally curved coolant channels (17,18), and where exit channels at the tip have been drilled after twisting, and where the exit openings (21,2) are located at different distances from the center line.

  • Patent number: 4219792
    Abstract: A device for effecting mechanical prestressing in a pair of substantially concentric cylinders, in which the inner cylinder is prestressed in compression and the outer cylinder is prestressed in tension by means of the device in the form of a hose or hoses disposed in a gap between the cylinders and being subjected internally to a pressure medium, the hose or hoses being arranged helically in such a manner that the sum of the moments of the forces thereby caused by the pressure forces between the cylinders and occurring about the central axis of the cylinders in a plane containing such axis, is substantially zero.
