Publication number: 20140147619Abstract: The present invention relates to a composite article 801, wherein the article has a longitudinal direction L and a transversal direction T, the article 80 comprises a stack of plies wherein one ply is a bottom ply and one ply is a top ply, most of or all of the plies comprise fibres, and the article comprises a plurality of plies having fibres substantially in the orthogonal direction 810 to the longitudinal direction L of the article 801 and the stack further comprises a plurality of plies having fibres substantially in the same direction 811 as the longitudinally direction L of the article 801 and/or a plurality of plies having fibres in the diagonal direction (812, 813, 815, 816, 817, 818) of the longitudinal direction (L) of the article (801), wherein at least one of the ply/plies having fibres substantially in the orthogonal direction 810 to the longitudinal direction L of the article 801 comprise fibres that are stiffer than the fibres in the other plies which have less stiff fibres.Type: ApplicationFiled: January 21, 2011Publication date: May 29, 2014Applicant: SAAB ABInventors: Tommy Grankaell, Per Hallander, Anders Lundberg, Tonny Nyman, Bjoern Weidmann, Mikael Petersson

Publication number: 20120256076Abstract: A method of producing a forming tool and a forming tool for forming an article. The forming tool includes a composite face sheet having a forming surface and an inner surface opposite the forming surface. A support structure is attached to the inner surface of the composite face sheet. The support structure includes a support shell of composite having a first surface facing the inner surface of the composite face sheet and having a second surface opposite the first surface. The support structure further includes distance members. The support shell is fixed at a distance from the composite face sheet by the distance members.Type: ApplicationFiled: November 17, 2009Publication date: October 11, 2012Inventors: Tommy Grankall, Anders Lundberg, Jan Andersson, Mikael Petersson, Björn Weidmann, Jan Waara, Per Hallander

Patent number: 7136583Abstract: Devices (13.1, 31.1) communicate with each other on a wavelength channel using wavelength specific signals on a working WDM fiber (21) having a parallel protection WDM fiber (23). An SDH system (13.S, 31.S) uses one channel of the WDM system of the fibers as one of the fibers of the working pair of the SDH system and has a separate fiber (37) constituting that fiber of the protecting fiber pair for the SDH-system. To provide an unambiguous or predictable protection behaviour for the SDH system for the case of the working WDM fiber being cut the RETs (29.1, . . . , 29.S) have two modes. In the first mode a RET will be on and always carry traffic when the input power is high enough. In the second mode a RET they will not automatically turn on again after it has first lost the input signal and thereupon the input signal has returned. The RET can then be manually restarted or restarted after some suitable delay. Then the sequence of events will always be unambiguously defined.Type: GrantFiled: December 28, 2000Date of Patent: November 14, 2006Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Magnus Oberg, Anders Lundberg

Publication number: 20030123876Abstract: The present invention is a method to protect a cross-connect OXC/OEXC used to forward at least one signal AB from a main input IN to a main output OUT. Said method comprises the following step: dividing the at least one signal AB into two substantially identical signal parts, a first signal part A and a corresponding signal part B; routing the at least one first signal part A through a first cross-connect OXC1/OEXC1, from the input IN to the output OUT; detection of a failure affecting the at least one first signal part A; interruption of the routing path for the at least one first signal part A; routing the at least one corresponding signal part B through a second cross-connect OXC2/OEXC2, from the input IN to the output (OUT).Type: ApplicationFiled: October 8, 2002Publication date: July 3, 2003Inventors: Erland Almstrom, Simon Storm, Magnus Oberg, Anders Lundberg

Patent number: 4684330Abstract: A compressor of the rotary type is driven by a motor via a gear wheel arranged on the shaft of the compressor and cooperating with a gear wheel arranged on the shaft of the motor, the gear wheels and the shafts being enclosed in a gear housing. The motor is fastened to a detachable wall part of the gear housing, and the motor shaft is journalled solely in the bearings of the motor and protrudes into the gear housing through an opening in the wall part. The opening is provided with sealing means which prevent a medium from forcing its way out of the gear housing. The gear wheels are accessible for dismantling and assembly when the wall part together with the motor is detached from the rest of the gear housing.Type: GrantFiled: August 24, 1981Date of Patent: August 4, 1987Assignee: Stal Refrigeration ABInventors: Lars Andersson, Rune Glanvall, Kjell Ericson, Anders Lundberg

Patent number: 4227755Abstract: A slide bearing journals the rotor shaft in the compressor housing with a clearance radially of the shaft; and an anti-friction bearing mounted on the shaft journals it axially thereof, the housing having a fixed support surface against which the anti-friction bearing abuts axially in one direction and which allows radial movement thereof. Yielding means are provided to press the anti-friction bearing against the support surface with a predetermined precise force.Type: GrantFiled: October 19, 1978Date of Patent: October 14, 1980Assignee: Stal Refrigeration ABInventor: Anders Lundberg
