Abstract: Liquid cooling station comprises at least one pump and at least one motor connected to the pump for operating the pump to circulate cooling liquid between the cooling station and an object to be cooled, a first cooling liquid outlet port for supplying the cooling liquid towards the object to be cooled and a first cooling liquid inlet port for receiving the cooling liquid from the object to be cooled. The liquid cooling station further comprises at least one connection block, which comprises at least one first cavity for receiving an operating part of the pump, at least one second cavity for an additional operational part, the first cooling liquid inlet and outlet ports and an internal channel system connecting the first cavity to the first cooling liquid inlet and outlet ports.

Abstract: An arrangement and a method are provided for cooling liquid-cooled electronics. The arrangement includes a pipe system, said pipe system including receiving and exit coolant flow pipes for connecting the arrangement to a liquid-cooling system of said liquid-cooled electronics, inlet and outlet coolant flow pipes for connecting the arrangement to a heat exchanger arrangement, and an expansion tank connected to the coolant flow pipes. The arrangement further includes a coolant level transmitter arranged to detect the amount of the coolant in the expansion tank, a temperature measure arrangement arranged for measuring temperature of the coolant in the arrangement, and a leakage control system. The leakage control system includes a calculator for calculating a temperature corrected reference value for the amount of the coolant in the expansion tank and for calculating a temperature corrected coolant volume by using said temperature corrected reference value.

Abstract: Input water is preheated in a heat exchanger (2), pumped (4) through another heat exchanger (5) into a heating unit (6). The heating unit heats the water to a temperature of above 100° C., preferably 140-150° C., while maintaining the water in a liquid state without vaporization. A pump (8) feeds the heated water under sufficient pressure to prevent vaporization to at least one crossflow filtration unit (9). A portion of the heated water passes through a thermally stable filtration material having a pore size of 1-20 nanometers for filtering endotoxins and pyrogens, 4-10 nanometers for filtering viruses, or 100 nanometers−30 &mgr;m for filtering bacteria. Heated water which has passed through the filtration material is fed through a pure water product outlet of the filtration unit to a pure water outlet (16). A retenate portion of the heated water flows past the filtration material to carry filtered impurities through a retenate output line (10).

Abstract: A method for forming a joint between a product formed of composite material including reinforcing fibers and a connecting piece includes forming the connecting piece with a shoulder within a joint region thereof and during the formation of the product, guiding the longitudinally extending reinforcing fibers of the composite material as continuous, unitary fibers through a first path within the joint region of the connecting piece toward the connecting piece shoulder, around the shoulder of the connecting piece, and then in a substantially opposite direction through a second path within the joint region of the connecting piece to return to the composite material of the product, whereby both the product of composite material and the joint between the product and the connecting piece are formed simultaneously.

Abstract: Method and device for collecting objects pointing out of the bottom level of seas or corresponding water areas so that the objects are carried from the bottom by using waterflow through an intake opening of the collecting device moving on the bottom of the sea. The objects are removed from the bottom by a removing device. The lowermost part of the removing device moves at the same level with the bottom of the water area or above it. The most suitable way of removing the objects from the bottom is by using water spray, the flow power of which is controlled separately from the flow power of the water in the conveying channel.
