  • Publication number: 20090223496
    Abstract: This document describes a device for cleaning of crankcase gases from a combustion engine, and a combustion engine having such a device. An inlet conduit is connected to a crankcase of the combustion engine. A centrifugal separator receives a flow of crankcase gases from the crankcase via the inlet conduit and comprises a routable centrifuge rotor for centrifuging the crankcase gases. A drive device drives the centrifuge rotor. An outlet conduit discharges cleaned crankcase gases from the centrifugal separator. The rotary speed of the drive device, and thus the rotary speed of the centrifuge rotor, is controllable depending on the gas pressure in the crankcase. An export conduit may be connected to the inlet conduit and adapted to enable discharge of a flow of crankcase gases from the crankcase by-passing the centrifugal separator depending on the gas pressure in the crankcase.

  • Publication number: 20090000258
    Abstract: In a centrifugal separator for cleaning a gas comprising liquid impurities, a stationary casing encloses a separation space having an inner wall surface. The separator comprises an inlet for the gas. A rotating member rotates around and brings the gas to rotation for separation of at least a main part of the liquid impurities from the gas. A gas outlet is provided downstream the rotating member for discharge of the cleaned gas. A first liquid outlet discharges the liquid impurities and comprises an outlet hole. An annular surface extends inwardly from the wall surface and is located downstream the outlet hole. The first liquid outlet comprises an annular shield element extending from the annular surface at a distance and radially inside the outlet hole.

  • Publication number: 20070249613
    Abstract: The use of tetrahydrofolate, methylene-tetrahydrofolate and/or methyl-tetrahydrofolate, and at least one multi-targeting antifolate, for the manufacture of a pharmaceutical composition for the treatment of cancer is disclosed. By combining the multi-targeting anti-folate with tetrahydrofolate, methylene-tetrahydrofolate and/or methyl-tetrahydrofolate, it is possible to remarkably reduce toxic side-effects without diminishing the anti-tumour action of the drugs. A pharmaceutical composition, a kit comprising the pharmaceutical composition as well as a method for the treatment of cancer are also disclosed.

  • Patent number: 7152589
    Abstract: Upon cleaning of crankcase gas generated during operation of an internal combustion engine in its crankcase, a centrifugal separator is used, which includes a rotor arranged for rotation by means of a driving motor and arranged by its rotation suck crankcase gas from the crankcase through a conduit to the centrifugal separator. During operation of the combustion engine a parameter, e.g. a measurement of the load on the combustion engine is sensed, the magnitude of said parameter being related to the amount of crankcase gas generated per unit of time in the crankcase. Depending upon a sensed change of the sensed parameter the rotational speed of the rotor of the centrifugal separator is changed in a way such that the gas pressure in the crankcase is maintained at a predetermined value, or within a predetermined pressure interval, during the operation of the combustion engine.

  • Patent number: 7056363
    Abstract: A centrifugal separator for cleaning of a gas from solid and/or liquid particles suspended therein, includes a stationary housing and a rotor arranged therein. The rotor at its one axial end has a central inlet for gas to be cleaned and delimits a central space communicating with the inlet. Around the central space a stack of conical separation discs is arranged in the rotor. These discs form between themselves several through flow passages which at their one ends communicate with the central space in the rotor and at their other ends communicate directly with a receiving chamber surrounding the rotor in the stationary housing. The rotor supports several turbine blades, which are arranged in a ring around the central inlet of the rotor, and at least one nozzle is adapted to direct a gaseous driving fluid towards the turbine blades for the rotor rotation.

  • Patent number: 7022150
    Abstract: In a centrifugal separator, the rotor of which is adapted to be driven by means of a gaseous driving fluid, the rotor itself supports a ring of turbine blades extending around the rotational axis of the rotor. A stationary nozzle is adapted to direct a flow of the driving fluid towards the ring of turbine members. After the driving fluid has passed between the turbine blades and has influenced them for driving of the centrifugal rotor, it enters a reversing chamber formed by a stationary reversing member. In the reversing chamber the driving fluid is caused to change its direction and is then conducted again towards the ring of turbine members in order to be utilized a second time for driving of the centrifugal rotor.

  • Patent number: 6821319
    Abstract: In connection with cleaning of gas from particles suspended therein and being heavier than the gas the gas is caused to rotate in a chamber delimited in a stationary housing, so that the particles by centrifugal force are separated from the gas and are thrown towards a stationary housing. The rotation of the gas is accomplished by means of a rotor, which includes a stack of conical separation discs arranged coaxially with each other and concentrically with the rotational axis of the rotor. The gas to be cleaned is caused to flow through interspaces between the separation discs, while they are rotating, the particles by the centrifugal force being brought into contact with the insides of the separation discs. In contact with the insides of the separation discs the particles first move along the generatrices of the separation discs and then move along inclined guiding members, which are arranged in contact with said insides.
