Abstract: A filter unit to be utilized in a continuous flow engine wherein the filter unit is adapted to filter a fluid stream, preferably a gas stream, wherein the filter unit provides a strainer part providing two strainer surfaces, wherein at least one of the two strainer surfaces is not planar. A kit contains a filter unit of this type and a counterpart adapted receive the filter unit, wherein the counterpart is adapted to be used as part of the continuous flow engine. A method utilizes such filter unit or kit.

Abstract: According to an aspect, there is provided an elevator car parking brake. An operating fork is configured to move within a housing in a direction perpendicular to an end surface of a guide rail in response to operating an actuator. When the actuator is operated to move the operating fork within the housing towards the guide rail to achieve a braking state, the operating fork is configured to push braking wedges towards side surfaces of the guide rail to contact the side surfaces. When the actuator is operated to move the operating fork within the housing away from the guide rail to achieve a brake release state, detaching means are configured to pull the braking wedges away from the side surfaces of the guide rail.

Abstract: The invention relates to rope gripping member for a rope gripping device, the rope gripping member comprising an elongated rope gripping face for being pressed against an elongated side face of an end section of a rope, the elongated rope gripping face having a longitudinal direction and a front edge and a rear edge; wherein tensile stiffness of the rope gripping member in longitudinal direction of the gripping face increases non-linearly with accelerating rate from the front edge towards the rear edge of the gripping face. The invention also relates to a rope gripping device, a rope terminal arrangement and a hoisting apparatus implementing the rope gripping member.

Abstract: A rope storage unit for storing an elevator rope during transportation and/or installation of the elevator rope includes a rope reel, formed by a rope wound in a spiral form and having a central axis; and a support frame provided with an inner space inside which the rope reel is positioned supported by the support frame such that it can in use be rotated in the inner space for unwinding the rope. The rope is a rod having a straight form when in rest state and elastically bendable away from the straight form, the rope being under substantial bending tension in the spiral form, and wherein the support frame comprises three or more rotatable support rollers delimiting the inner space and surrounding radially the rope reel. A method for installing an elevator rope implements the rope storage unit.
