Abstract: Arrangement for accumulation and evacuation of water such as defrosting and condensation water from refrigeration units, the system including a piping arrangement with a vertical pipe section extending from a water evacuation unit provided in conjunction with the respective refrigeration unit; discharge valves, one for each unit; one or more liquid reservoir for each unit; one or more vacuum pumps; air inlet nozzles; a control unit; one or more level switches and air conduit inlet opening for each vertical pipe. Each of the water evacuation units includes a docking station and a water collection tray preferably to be slideably provided within the docking station, whereby each unit is custom made to fit between the refrigeration unit and floor where the refrigeration units are placed.

Abstract: Liquid ring screw pump (1) including a housing (2) with a suction inlet section (4) and a pressure outlet section (3) and within the housing (2) rotatably provided Archimedes screw rotor driven by a motor (6) via a shaft, the inlet section (4) and outlet section (3) each provided with connecting means for suction and pressure piping respectively. The pump and motor is constructed with a single leg or support or single pair of legs or supports (10) provided preferably at a weight balance point between the motor (6) and pump (1).

Abstract: The present invention relates to a mobile joint (1) with spring resistance, suitable for a sitting device, comprising a first and a second joint element (10, 20), which are pivotally connected by a shaft (3), to allow tilting of the sitting device caused by the displacement of the users weight, comprising a first and a second parallel plate spring (18, 19) with first and second ends, with an intermediate blocking element (11), wherein each plate spring (18, 19) in the first end are connected to the first joint element (10), and in the second end are glidingly abutting the second joint element (20), the first and second plate spring (18, 19) each having an axis of rotation that is displaced in relation to each other and the shaft (3).
