Abstract: The invention relates to a conveying system for moving containers (14), the conveying system (4) comprising an inclined track (8) and a conveying device (24), where the track (8) has an container inlet (11) at the bottom (12) and an container outlet (15) at the top (16) and where the conveying device (24) is arranged to travel down (R) the track (8) and comprises a container moving unit (54) which after passage below a container (14) moves the container (14) one step up (L) the track (8), the conveying device (24) thus moving one container (14) at a time one step up (L) the track (8) during the downward (R) travel of the conveying device (24). The invention also relates to a tower structure (2) comprising a container conveying system (4), and a method for conveying containers (14) with a conveying system (4).

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 is reserved if it is available. It is detected if a valid delivery of the requested service has been performed, if so, the delivered amount of said requested service is accumulated; and available amount is updated in dependence of the delivered amount.

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 maneuverable by a driver of the vehicle.
