Abstract:
A wall module (7) arranged to be used as at least a part of a wall in a building (8) and a building with such a wall module (7) is described. The wall module comprises at least two load bearing studs (11), at least one outer cover board (12) arranged on the outside of the load bearing studs (11) and at least one inner cover board (13) arranged on the inside of the load bearing studs (11). The cover boards (12, 13) span over the space between the load bearing studs (11). Insulation (14) in the form of cellular plastic is arranged between the load bearing studs (11) and between the cover boards (12, 13). At least one of the load bearing studs (11) comprises an inner beam (2), an outer beam (3), a block (4) of cellular plastic arranged between and glued to the inner beam (2) and the outer beam (3), and two beam boards (5, 6) which are arranged on each side of, span over and are glued to the inner beam (2), the block (4) of cellular plastic and the outer beam (3).
Abstract:
A tracked vehicle, especially a snow scooter, that has two laterally spaced-apart front drive-track assemblies (10), each of which is turnable around a substantially vertical axis and which are coupled for common turning. Each drive-track assembly is carried by a vehicle chassis (11) via a vertically movable link device, which in respect of vertical turning rests against the chassis via a spring-damper assembly (7), and the drive-track assemblies are mechanically coupled by a parallel steering mechanism (23-26), which is manoeuvrable by a driver of the vehicle.
Abstract:
A method and system for updating the available amount of a service to be used by a user in a communications system, wherein a requested amount of a requested service (100) is reserved (101,102) if it is available.
