Abstract: The subject of this invention are native forms of fucoidan polysaccharide, desulfated fucoidan and derivatives obtained by processing to the level of fucose-oligosaccarides containing preferentially, but not exclusively less than 20 monosaccaride fucose units alpha-linked by a glycosidic bond, with an average molecular weight of preferentially less than 3 kDa. The poly- and oligosaccarides that are described according to the invention are natural and safe, and are used as a dietary supplement for the use in prevention and treatment of pathologies associated with Noroviruses or Rotaviruses, Salmonella sp. or Pseudomonas aeruginosa or Campylobacter jejuni and other enteroviruses and enteric pathogens that cause bacterial gastroenteritis, as well as in the food production process. The invention also relates to a method for the desulfation and fragmentation of fucoidans to generate desulfated poly- or oligo-fucoses.

Abstract: A switching device configurable as a grounding device, a disconnecting device, and a combined disconnecting/grounding device is disclosed. The switching device includes an encapsulating housing, a stationary grounding contact fixed to the housing, a stationary disconnector contact fixed to a first conductor, and a moveable contact that is movable along an axis and engagable with the grounding contact and the disconnector contact. A conductor tube is fixed to a second conductor and accommodates the moveable contact. A drive for driving the moveable contact has a retaining element that is movable along the axis and is guided in the conductor tube. The retaining element accommodates two contact tubes. A first contact tube forms a mating contact of a grounding device containing the stationary grounding contact. A second contact tube forms a mating contact of a disconnector containing the disconnector contact.

Abstract: The high-voltage switching device used in one installation position and has metallic encapsulation (10) a switching gap (4) and a particle trap (1) for holding foreign body particles (2), and is characterized in that in the one installation position, the particle trap (1) is arranged vertically underneath the switching gap (4), in the one installation position, an isolator part (8) is provided, which has a surface (8a) aligned essentially horizontally and faces the interior of the high-voltage switching device, with a metallic wall (9), which is higher than the particle trap (1; 1?), being arranged between the isolator part (8) and the particle trap (1; 1?). The particle trap (1) has a viewing window (3). If the high-voltage switching device is a disconnector, this viewing window (3) may be identical to the viewing window (3) for visual access to the visible disconnecting gap (4) of the disconnector.

Abstract: The switching device contains an encapsulating housing (1) filled with insulating gas. A grounding contact (14) and a disconnector contact (15) are held in stationary fashion in the interior of the housing (1). In addition, a moveable contact element (9), which can be displaced along an axis (8) and can be brought into or out of engagement with at least one of the two contacts (14, 15), is arranged in the housing interior. A drive (13), which is guided through the wall of the housing (1) and can have force applied to it from the outside, acts on the moveable contact element (9). This drive (13) has a retaining element (12), which can be displaced along the axis (8) and is guided radially in the conductor tube (11). The moveable contact element (9) comprises at least one of two contact tubes (9?, 9?), which can preferably be detachably connected to the retaining element (12).

Abstract: A compact earthing switch (1?) is provided by a mounting lid (10) of the gas-insulated switchgear assembly (15) having a concave physical volume (100) which extends the gas chamber (9) and by the earthing switch fixed contact (12) being mounted on an inner side (10e) of the mounting lid (10) and being arranged at least partially in the physical volume (100) of the mounting lid (10). Exemplary embodiments relate, inter alia, to: an essentially cylindrical mounting lid (10; 10a 10e); an earthing switch fixed contact (12) having a physical length (L) which is smaller than an axial physical depth (T) of the physical volume (100); and a large diameter (D) of the mounting lid (10) for simplified mounting and maintenance of active parts 7a, 7b) in the switchgear assembly (15).
