Abstract: An air-driven hydraulic pump, comprising an air motor, and an oil pump, which is operatively connected with the air motor, wherein the air motor includes a cylinder element in which an air piston is arranged movable in a reciprocating manner along a centre axis. The air piston is connected with an oil piston of the oil pump for transmitting the reciprocating movement of the air piston to the oil piston. The air piston separates a first cylinder chamber from a second cylinder chamber within the cylinder element. A control valve element is arranged to control the application of pressurized air from a source of pressurized air to the cylinder element. At least one pressure control valve is arranged in the air motor, allowing an air flow from one of the cylinder chambers to the other cylinder chamber when the pressure difference between the two cylinder chambers exceeds a predetermined value.

Abstract: A contact element for making an electric contact to a contact member for enabling an electric current to flow between the contact element and the contact member. The contact element includes a body having at least one contact surface thereof coated with a contact layer to be applied against the contact member. The contact layer includes a nanocomposite film having a matrix and crystallites of nano-size embedded therein. Portions of the matrix separating adjacent the crystallites of the nanocomposite film have a thickness providing the matrix and hence the film with an electrical conductivity determined by a substantially two-dimensional character of the matrix.

The contact layer includes a nanocomposite film having a matrix of amorphous carbon and crystallites of nano-size, i.e. with dimensions in the range of 1-100 nm, of at least one metal carbide embedded therein.

Abstract: The method is for converting a vertically standing up-flow tower by inserting a freely insertable pipe into the conical part of the up-flow tower the tower is converted to a down-flow tower where the tower can easily be restored to the up-flow tower and optimized with regards to a minimized stagnation volume in the tower. The upper open end of the pipe is disposed at a first distance (A) from the lower part of the conical inlet part. The first distance (A) is less than the total vertical extension (B) of the conical inlet part. The cellulose pulp establishes a self-forming stagnation zone around the pipe at a lower part of the down-flow tower.

Abstract: The invention concerns an arrangement to counteract problems associated with mixing in steam into a pipe that is transferring a flow of pulp of medium consistency. The arrangement comprises a chamber (101) with a cross-sectional area (A3), and a pre-determined length (x). The chamber (101) is in connection, upstream to the flow of pulp, with a first throttle section (107) that has a cross-sectional area (A1). The addition of steam through supply means (105) takes place in the first throttle section (107). The chamber (101) is in connection, downstream to the flow of pulp, with a second throttle section (122) that has a cross-sectional area (A2). The cross-sectional area (A3) of the chamber is greater than the cross-sectional area (A1) of the first throttle section and the cross-sectional area (A2) of the second throttle section.

Abstract: This is a device and a method for withdrawing cellulose pulp with a pulp concentration of 8-14% from a cylindrical storage tower. The storage tower has a plane bottom and with a diameter that exceeds 3 meters. A pipe is arranged through the wall of the storage tower that is parallel to the bottom of the tower and directed towards the center of the tower. The pipe has at one of its ends an obliquely cut opening that faces upwards in the tower. The pipe is attached at its other end to an MC pump to be able to pump out cellulose pulp from the storage tower.
