Abstract: The invention relates to a rotary device (101) for a down-the-hole hammer (1), which rotary device is accommodated in a rotation motor housing (3) and mounted behind a drill housing (2) for transferring a torque to a drill bit (8) and a pressurized drive fluid (22) to a striking mechanism (4) for the drill bit. The rotary device includes a cam curve with a plurality of drive lobes (28:1-28:3) and working chambers (30:1, 30:2, 30:3) along a circumference in the rotation motor housing (3), a rotor disc (38) carrying a plurality of radially movable vanes (40:1-40:12), which are accommodated in piston tracks (41:1-41:12) in the rotor disc.

Abstract: An armrest for a vehicle seat includes a seat cushion and a backrest. The armrest is intended to be turned around a pivot axis between a first active position and a second folded-away position. The armrest includes an upper part, which in the active position is positioned with its longitudinal axis substantially parallel to a substantially vertical plane through a side surface constituting an outer edge surface of the vehicle seat and intended to support a user's forearm, and at least one lower part provided with a fixing device for attaching the upper part to the vehicle seat. The lower part includes a linking mechanism arranged for setting the upper part in a transverse direction between a first position outside the side surface and an adjustable second position, and a locking device that is arranged to activate a catch that locks the upper part in a set position after it has been moved to the second position. A vehicle seat provided with an armrest and to a vehicle including an armrest are also provided.

Abstract: An armrest for a vehicle seat includes a seat cushion and a backrest. The armrest is intended to be turned around a pivot axis between a first active position and a second folded-away position. The armrest includes an upper part, which in the active position is positioned with its longitudinal axis essentially parallel to an essentially vertical plane through a side surface constituting an outer edge surface of the vehicle seat and intended to support a user's forearm, and at least one lower part provided with a fixing device for attaching the upper part to the vehicle seat. The lower part includes a linking mechanism arranged for setting the upper part in a transverse direction between a first position outside the side surface and an adjustable second position, and a locking device that is arranged to activate a catch that locks the upper part in a set position after it has been moved to the second position.

Abstract: A method improves the performance of a jetting assembly in an apparatus for jetting droplets of viscous medium on the fly onto a substrate. The jetting assembly is releasably mounted in the apparatus and includes a nozzle, an ejection mechanism connected to the nozzle, and a viscous medium container connected to the eject mechanism. Information relating to an XY-position and a Z-position is obtained together with information regarding the exit velocity a droplet of viscous medium has when it exits the nozzle. The information is used as a basis for adjusting a trigger position of the nozzle for the subsequent jetting of droplets. A jetting assembly also includes a storage device arranged to receive and hold calibration information of properties of the assembly obtained during calibration measurements.
