A system and method for accumulating pressurized liquefied gas or cryogenic fluids in which a source supply of liquefied gas or cryogenic fluid is fed to a pump which pressurizes the fluid and feeds it to a liquid accumulator. The invention is in particular useful for producing digitised film representing an object rotating about its centre of rotation. The connecting strips are attached by outer edges to the profile elements through very thin neck portions that keep the elements together during the pouring of the slab. The reflector defines several light transmission holes.
