Abstract: A filter unit is provided for filtering a liquid. The filter unit is intended to be connected to a cap including a first liquid passage and a second liquid passage 114. The filer unit includes: a canister; and a filter cartridge rotatably arranged within the canister, the filter cartridge includes a first filter connection for liquid to pass through, the first filter connection is intended to be connected to the first liquid passage in the cap, wherein the canister is intended to be rotatably attachable to the cap such that, when the canister is attached to the cap by a rotating action, the filter cartridge is stationary to the cap.

Abstract: The present invention relates to a wheelchair wheel attachment and gear change adaptor unit for a geared wheelchair wheel having a hub which comprises an attachment shaft protruding to one side thereof, and where gear change is actuated by axial manipulation of a rod running within the shaft in a cylindrical bore which is concentric with the shaft. An adaptor housing (1) is designed to receive and support the shaft in an opening (19). Locking means are provided for releasably locking the shaft to the adaptor housing (1) such that the shaft cannot move out from the adaptor housing (1) until the locking means are released. A gear shift plunger (5) is arranged for hydraulic activation within the adaptor housing (1) such as to, upon activation when the wheelchair wheel is attached to the adaptor unit, push the rod outwards of the adaptor housing (1) towards the hub for effecting gear change in the hub.

Abstract: An applicator adapted for applying a liquid from a source of liquid to the skin of an individual subject. The applicator includes a housing delimiting a chamber, and a roller rotatably mounted in the housing with an adhesion side extending into the chamber and a transfer side extending out of the chamber. A cylinder is attached to the housing, at least one outlet and one through hole which are formed in the wall of the cylinder, is connecting the cylinder to the source of liquid and to the chamber, respectively, with the through holes axially and angularly displaced in relation to each other. A slider is arranged for sliding between first and second positions in the cylinder, a recess is formed in the slider, and the recess communicates with the source of liquid in the first position of the slider via the at least one first through hole and with the chamber in the second position of the slider via the at least one second through hole.
