Abstract: A housing (21) for holding a light consumable (22) or a mounting unit (42) on which the light consumable (22) is mounted. The housing includes at least one opening (23) for receiving the light consumable (22) and allowing transmission of light from the light consumable when mounted in the housing (21). An electrical connection means having first and second parts (29A) and (29B) provide the electric power to the mounted light consumable. A holding means further includes a first part of a magnetic means whereby a second part of the magnetic means mounted on an elongated arm which can be positioned adjacent the first part of the magnetic means and provide magnetic force at the opening so as to withdraw the light consumable or the unit on which the light consumable is mounted from within the housing.

Abstract: A conveyor for buffering products comprises at least first and second drivable curved conveyor parts, which are spaced from each other in horizontal direction. At least, the first conveyor part has at least an inner track and an outer track, wherein the outer track is adjacent to the inner track and disposed at the outside bend side of the inner track. The second conveyor part has at least a second conveyor part track, wherein one end of the outer track of the first conveyor part is coupled to one end of the second conveyor part track. An other end of the second conveyor part track is coupled to one end of the inner track of the first conveyor part. The first and second conveyor parts are at least partly helically-shaped.
