Abstract: The present disclosure provides a sub-assembly of a medicament cassette unit, the sub-assembly including a tubular housing, a delivery member cover, and a cap. The tubular housing extends along a longitudinal axis between a proximal end and a distal end. The tubular housing is configured to receive a medicament container. The delivery member cover comprises a tubular section arranged telescopically relative to the proximal end of the tubular housing. The delivery member cover comprises a distally directed surface. The cap is releasably attached to the tubular section of the delivery member cover, and the cap comprises a proximally directed surface adjacent to the distally directed surface of the delivery member cover.

Abstract: The present disclosure provides a sub-assembly for a medicament delivery device. The sub-assembly includes a housing and a delivery member cover arranged in the housing and configured to move axially in the housing from an extended position towards a retracted position. The delivery member cover includes a radial wall provided with an axial through-opening. The sub-assembly further includes a removable cap assembly. The removable cap assembly includes a cap configured to be fitted to the delivery member cover and/or to the housing, a distal cap end, and a delivery member shield gripping sleeve having a radially flexible axially extending arm.

Abstract: The present disclosure provides a sub-assembly for a medicament delivery device configured to expel medicament from a medicament container. The sub-assembly comprises a housing and a medicament container carrier. The medicament container carrier comprises a carrier wall having an open proximal end, at least one slot, and at least a first leg portion and a second leg portion radially separated by the slot. The sub-assembly further comprises a first retaining structure of the housing, and a second retaining structure of the first and second leg portions. The first retaining structure exerts a force on the second retaining structure at least in the circumferential direction to prevent the first and second leg portions from moving radially outwards.

Abstract: A trimmer head (1) comprises a rotatable housing (12) connectable to a trimmer line spool (13) rotatably supported by said housing (12) and a locking mechanism (14) for locking the trimmer line spool (13) to the housing (12) with a locking force (FL). The locking mechanism (14) is arranged to be moved from a locked to an unlocked position when a rotation speed of the trimmer head (1) is increased above an operating speed. The increased rotation speed causes a releasing force (FR) greater than the locking force (FL). In the unlocked position, the locking mechanism (14) releases the trimmer line spool (13) from the housing (12) such that the trimmer line spool (13) is movable and a trimmer line (3) spooled around the spool (13) is released and pulled out by a centrifugal force (Fc) caused by the rotation of the trimmer head (1), allowing feed of the trimmer line (3).

Abstract: A power tool (1) is disclosed comprising an electric motor (3) configured to power a tool (5) of the power tool (1), a power supply arrangement (7, 9) configured to supply electricity to the electric motor (3), and an air-cooling path (11, 11?) extending past at least portions of the electric motor (3) and the power supply arrangement (7, 9) so as to cool the electric motor (3) and the power supply arrangement (7, 9) when air is flowing through the air-cooling path (11, 11?). The power tool (1) further comprises a fan (13) arranged in the air-cooling path (11, 11?) between the electric motor (3) and the power supply arrangement (7, 9). The fan (13) is configured to generate an air flow through the air-cooling path (11, 11?) in a flow direction (d) from the electric motor (3) towards the power supply arrangement (7, 9).

Abstract: A method of controlling operation of a hand held power tool may include receiving information indicative of a type of cutting equipment attached to the hand held power tool (100) based on operation of a working assembly (130) in a selected direction of rotation. The working assembly (130) may be configured to be bi-directionally rotatable to perform a cutting function using cutting equipment attachable to the hand held power tool (100). The method may further include determining the type of cutting equipment attached based on the received information, and selectively inserting an operational constraint on the working assembly based on the type of cutting equipment and a selected direction of rotation for the working assembly.
