Abstract:
Shielding apparatus has a number of shielding units 1. Each shielding unit (1) includes two planar sheet members (2, 3). The sheet members (2, 3) are arranged such that a planar surface of one of the sheet members (2) covers a planar surface of the other of the sheet members (3). The planar surfaces of the sheet members (2, 3) are of substantially the same dimensions and the sheet members are mutually offset (6) from each other so that a portion of the planar surface of each sheet member (2) is not covered by the other sheet member (3).
Abstract:
A building material guarding against a sick house (indoor air pollution) and using coffee grounds after drinking as a recycled resource, and an installation method thereof. A building material giving combined performance effects including sound-proofing/vibration controlling performances added by further mixing into the above building material the shreds or powder of discarded used tires. The building material consisting of recycled resources, characterized by comprising a laminate and a platy material covering the laminate thereinside, the laminate being formed by consolidating with a plaster material a raw material obtained by drying coffee grounds after drinking coffee (made by roasting and grinding coffee beans) or obtained by further roasting the dried coffee grounds; and the building material consisting of recycled resources, characterized by comprising a laminate and a platy material covering the laminate thereinside, the laminate being formed by mixing into the raw material consisting of coffee grounds shreds and/or powder obtained by shredding used tires and further mixing the resultant material into a plaster material for consolidating.
Abstract:
The invention relates to a method for attenuating magnetic interference in a test room (1, 2, 8, 9) equipped with a shield of ferromagnetic material, in which method the interfering magnetic field is measured and a compensating field is generated on the basis of the measurement result. According to the invention, the interfering field to be measured is resolved in three magnetic field components oriented in different directions, each one of said magnetic field components (x, y, z) is measured with the help of coils (3, 4, 5, 6) wound about the wall elements (1, 2, 8, 9) made from said ferromagnetic material in a manner wherein a flux component passing through at least one of the wall element (1, 2, 8, 9) made from said ferromagnetic material that is oriented parallel to one of said magnetic field components (x, y, z) is measured with the help of coils wound about said wall element.
Abstract:
A field erectable nonflammable radio wave absorber which comprises a main radio wave absorbing member fixed to a wall surface, a ceiling surface or a floor surface of a radio wave darkroom, and a cap put on the main radio wave absorbing member, and which is formed by combining in a construction field a radio wave absorber-assembling board, which has foldable portions and/or portions to be bonded, and which can be assembled into a hollow pyramidal, wedge-shaped, polygonal or wavy body in a construction field, with a carbon-containing inorganic short fiber board or an organic foam board so as to form a hollow pyramidal, wedge-shaped, polygonal or wavy body.
Abstract:
An ember-blocking vent screen for covering a roof vent comprises a screen section and at least two strips of pressure sensitive adhesive (PSA) heavy duty tape attached at opposite edges of the screen section such that deployment portions of the tape strips overlap and extend transversely beyond their respective screen edges. The screen section is made of stainless steel or aluminum wire, has interstices sufficiently small to block passage of small minimum diameter embers therethrough, is lightweight, and is sufficiently malleable to be capable of conforming to the contour of the vent being covered. The deployment portion of the tape strips is such that deployment portions of the tape extend transversely (i.e., widthwise) beyond respective screen edges covered with a release liner that is removable for installation of the screen
Abstract:
A shielding system includes a plurality of transportable modules, wall panels, or pods that are connectable to form a containment area and to define a radiation barrier. Each of the plurality of transportable modules has a first radiation wall defining the containment area, a second radiation wall spaced apart from the second wall, and a radiation shielding fill material positioned between the first radiation shielding wall and the second radiation shielding wall. The radiation shielding fill material includes one of a superabsorbent polymer (SAP) filling a portion of a void between the first radiation wall and the second radiation wall, or a non-Newtonian fluid completely filling the void between the first radiation wall and the second radiation wall. A quantity of the radiation shielding fill material is sufficient to substantially reduce measurable radiation level outside the containment area.
Abstract:
Заявлено устройство для защиты от флюидного воздействия, которое может быть применимо для защиты стационарных объектов (небоскребы, горные станции, дирижабли, здания и другие) в случаях экстремальных природных явлений или для устранения лобового сопротивления транспортных средств. Устройство предназначено для установки в тело защищаемого объекта и состоит из одной или нескольких камер захвата, к каждой из которых подсоединен впуск флюидного провода дугообразной формы, вдоль которого расположены один или нескольких вертикальных разделительных барьеров. Буферная панель соединена с выходом флюидного провода, а между выходным отверстием флюидного провода и буферной панелью расположена выпускная шахта.
