en studie om mervärdet av Mäster Gröns co-branding med Svenskt Sigill
… out what added value Mäster Grön gets from their co-branding with the Swedish Seal of quality. The main topic of discussion was; how much value added does this co-branding give to Mäster Gröns pot plants? Are there differences from a customer point of view in value added between …
… about the experiments with mixing of the separated water and the vacuum pump seal water at Hellisheiði power plant. This is done to prevent silica scaling and clogging in pipes and reinjection wells as well as eliminating vacuum pump seal water from the plant. The experiments …
… this work should develop a machine to perform tests on a new type of piston seal that hopefully could be used in the future. The steam engines will be both volumetric and energy compact, around 1600 hp/literof cylinder volume, and it will have a lot of practical applications …
The background for this degree thesis is a need to replace the existing seal used to protect equipment containing secret or sensitive equipment used by Swedish Defence. The target design should satisfy both the need for tamper evidence and reduce Life Cycle Cost. In developing a …
… concerning a few different faults. Based on this investigation a choice on seal box condition and water leakage is made as problem for a more thorough examination, in which it is concluded that the turbine water leakage is larger when the turbine is put into operation. The …
This thesis has the overall objective to develop the optimum sealing system between the retarder and transmission. Today, there is a pressure-relief and two radial seals separation between the retarder and transmission. It has been found that carbon residue formation may occur …

… one placed spruce twigs and on top of the spruce twigs soil was shovelled to seal out air. The pine timber was then lit, and the timber was left to release its tar in to a barrel at the bottom of the trench. Pot ash is the ash one get when beech or other hardwoods with high …
… of fibers increases until the rotation of the impeller is disturbed or the sealing malfunctions. Two concepts are recommended for further development. They are called ”Vågen” (?The Wave?) and ”Tätningshylsan” (”The Sealing Cartridge”). Vågen has got two wave shaped flanges that …
