Abstract: The invention relates to a sample handling and storage system. The system is used for storing and handling samples, which may be cryogenic samples, that are arranged for use in charged particle microscopy, such as cryo-electron microscope samples for use in cryo-transmission electron microscopy. The system comprises a storage apparatus for storing a plurality of samples, and a Charged Particle Apparatus (CPA), such as a cryo-TEM, at a location remote from said storage apparatus. The system further comprises a transfer device that is releasably connectable to said storage apparatus, and that is releasably connectable to said CPA as well. As defined herein, said transfer device is arranged for acquiring a sample from said plurality of samples when connected to said storage apparatus, and arranged for transferring said sample from said transfer device to said CPA when connected to said CPA.

Abstract: A gas valve having a valve member disposed within a valve cavity, and an elastomeric valve seat extending from a valve cavity wall into the valve cavity. The valve member is movable between an open position in which the valve member does not engage the resilient valve seat thereby permitting gas to flow through the gas valve, and a closed position in which the valve member does engage the resilient valve seat thereby preventing gas to flow through the gas valve. In some embodiments, the elastomeric valve seat extends radially into the valve cavity from a groove formed in the valve cavity wall.

Abstract: A gas valve may include a valve body and a valve member disposed within the valve body. A resilient sealing ring may be disposed within the valve body such that the valve member achieves a closed position when the valve member contacts the resilient sealing ring. In some instances, a gas valve may include both an upper resilient sealing ring and a lower resilient sealing ring. The upper resilient sealing ring and the lower resilient sealing ring may both permit overtravel.

Abstract: A gas valve may include a valve body defining an upper valve seat region, and in some cases a lower valve seat region. A main valve that includes an upper main plate, and in some cases a lower main plate, may be disposed within the valve body. A control valve that includes an upper control plate, and in some cases, a lower control plate may be coaxially aligned with the main valve. The main valve may provide shut-off functionality while the control valve may provide flow control.

Abstract: Cellular foil (3) is unfolded between the surface of earth base course (1) and the first floor layer (5) during building the subsoil, which cellular foil (3) is poured over with fill (4) from loose material at least up to filling the compartments. A bedding (2) from loose material, optimally from sand, is created under the cellular foil (3). Geotextile (6) may be incorporated to the area under the cellular foil (3). Bedding (2) of lower grain size than that of the fill (4) is preferably used, wherein the fill (4) has optimal grain size of 8 to 63 mm. Compaction is done by at least eight travels of roller of 10 to 11 tons weight, also including vibrations when the height of fills is exceeding 25 cm above the cellular foil (3).
