摘要:
A sliding door assembly is provided comprising a first door having a tortuous leading edge, a door frame, a guide track, and a member having a complementary tortuous edge to that of the door. The drive assembly includes magnets to drive the door between open and closed positions. Radiation therapy facilities, especially those involving high energy X radiation or neutron radiation, require particularly thick walls, doors, and barriers.
摘要:
Biomass (e.g., plant biomass, animal biomass, and municipal waste biomass) is processed to produce useful intermediates and products, such as energy, fuels, foods or materials. Systems, methods and equipment are described for upgrading process streams using electrodialysis or electrodialysis reversal.
摘要:
The present invention relates to a building complex (100) of the type containing eight construction elements (2) for residential use, situated at a suitable relative distance so as not to create visible interference with each other. Each construction element (2) for living purposes has a square plan base (3), at least an internal patio element (4) , and at least one entrance faςade (5). Each construction element (2) for residential use comprises a series of carrying building structures (6) situated along the perimeter of each construction element (2) for residential use.
摘要:
The present invention is directed to interlocking building block with continuously curved surface profiles suitable for general wall construction, and, when using desireably dense materials, particularly suitable for constructing walls capable of significantly blocking electromagnetic radiation, such as photon, gamma, and neutron radiation.
摘要:
Es wird eine Vorrichtung zur Abschirmung eines Flächenbereiches mit einer Sperrschicht. insbesondere zur Abschirmung von Bauwerken gegen ein Eindringen von Radonstrahlung und/oder Feuchtigkeit beschrieben. Als Sperrschicht ist dabei ein als Schicht-Verbundwerkstoff aus unterschiedlichen Abschirmmaterialien ausgebildetes Flächengebilde vorgesehen. Hierbei ist vorteilhaft, dass durch die dadurch erzielte Kombination unterschiedlicher Abschirmmaterialen, die jeweils für sich genommen bereits gute Sperrwirkungseigenschaften haben, synergetische Effekte erzielt werden können, durch die die Abschirmwirkung gegenüber bekannten Sperrschichten entscheidend verbessert werden kann. Vorzugsweise weist der Schicht-Verbundwerkstoff Abschirmmaterialien (1, 3, 4) auf der Basis von Polyethylenterephthalat (PET) und/oder auf der Basis von Aluminium und/oder auf der Basis von Polyethylen auf.
摘要:
Device for partitioning and closures of vertical type, which comprises a series of reinforcements of board form consisting of a panel (1) or various contiguous panels, totally or partially surrounded with profiling (2-4), which have, on their faces, a plurality of channels (11) made in their surface and forming a relief that serves as a key for cement or mortar or plaster (6), and, depending on the panels used, this element may serve as thermal, acoustic or electromagnetic insulation, as shielding or as protection against radiation of any type.
