Abstract: A roof design has an external sheet covering (1), an insulating layer (3) provided beneath the sheet covering (1) and a load carrying structure (10) that supports the insulating layer (3). It is significant of the roof design that elements (7) for transporting an energy absorbing medium is provided in the insulating layer (3).

Abstract: A method for estimating the resemblance of various objects comprises the step of recording (40) data of a real object using a communication device. Furthermore the following steps are included: transferring (41) said recorded data to a service server, extracting (42) a comparison object from said recorded data, making (43) a resemblance analysis between the comparison object and a previously stored object, and transferring (44) result data containing information about the resemblance analysis to a result unit.

Abstract: An initiating element of non-primary explosive type comprising a confinement containing secondary explosive, having a first end adapted for ignition of the secondary explosive by igniting means, optionally via delay and flame-conducting pyrotechnic compositions, a second end adapted for delivering a detonation impuls and a intermediate portion in which the secondary explosive upon ignition is able to undergo a deflagration to detonation transition. At least a part of the secondary explosive is modified to give increased reaction rates at low pressures.

Abstract: A block for enclosing, holding or connecting in a signalling pyrotecnical network exploding pyrotecnic ignition devices, such as cords or detonators. The block comprises, in sequence from a centrally arranged ignition device (9), an inner wall (2) substantially surrounding at least an axial part of the ignition device, an empty space (7), or a material of lower density than in the inner wall, substantially surrounding the inner wall, an outer wall (1) substantially surrounding the inner wall and the space and fixation means (6, 8, 12) for keeping the ignition device, the walls and space in said positions. The block may have an annular inner space (65) or channel spaces between the ignition device and the inner wall and fixation means (35,66,69) for keeping the ignition device, the walls and space in the stated positions, whereby the inner wall is axially slitted (33,64).
