Abstract: The elevator car includes a floor, a ceiling, and side walls connecting the floor and the ceiling. At least the inner surface of at least some of the side walls of the elevator car may be covered with sheets of board. The board includes a fire retardant plywood having a front surface and an opposite back surface. The front surface of the fire retardant plywood may be coated with a first material layer including a fire retardant laminate. The fire retardant laminate may be attached with heat resistant or fire retardant glue to the fire retardant plywood. The back surface of the fire retardant plywood may be coated with a second material layer having a same thickness and a same material properties as the laminate.

Abstract: A liquid separator removing a liquid from a sample of a breathing gas flowing through an airway adapter having a channel surrounded by a wall is disclosed herein. The separator includes a chamber receiving the sample, and a membrane having an outer surface exposed to the gas flow, the membrane at least partially surrounding the chamber, which membrane separates the liquid received by the chamber. The separator also includes a supporting structure for supporting the membrane, and a connector operationally attached to the supporting structure, the connector being connectable to the adapter. The connector comprises a cavity providing a flow path for the sample from the chamber through an opening of the cavity to a sample tube. The membrane branches from a central part of the channel into at least two different branches extending to different directions.

Abstract: A housing for a substance removing an undesired component of a respiratory gas is disclosed herein. The housing includes a first space for the substance and a first wall surrounding part of the first space. The housing also includes a first end, surrounding part of the first space, comprising a first opening for the gas communication with the first space, and a second end, surrounding part of the first space, comprising a second opening for the gas communication with the first space. The housing further includes a first channel between the first and the second end for the gas flow, the first channel comprising a first orifice at the first end and a second orifice at the second end. The first orifice, the first opening, the second orifice and the second opening are in flow communication with outside the housing.
