Afin de contrer une inondation, l'opération typique et la plus efficace consiste à la construction d'une digue en empilant des sacs remplis de sable. La présente invention apporte un nouveau concept de sacs réutilisables afin d'améliorer la logistique et de diminuer les coûts.

An air filter for effectively filtering bacteria, fungi and viruses from the air. The air filter comprising of a carrier substrate impregnated with iodine resins effectively immobilizes and attenuates bacteria, fungi and viruses contained in passing air. The air filter may be employed in combination with a multi-layered air filter to provide a filter which effectively purifies passing air of a var...

At least one connector (18, 19) is mounted on the circuit board part (12) of the battery so that they lie within the outer contours of the board, and then these connectors are linked to the printed circuit. The circuit board is placed inside the battery casing (30), followed by the battery cell (20), so that the pole tabs (21, 22) overlap with the connectors. These tabs are then spot-welded to the...

A sound attenuating wall or ceiling assembly includes: a plurality of wall or ceiling boards; a series of parallel spaced apart, elongated framing members; and a series of elongated sound attenuating members extending along the length of the framing members, secured to the framing members and securing the boards to the framing members. Each of the sound attenuating members has a resilient cantilev...

Granules based on titanium dioxide with the characteristics: Average particle diameter: 10 to 150.mu.m BET surface area: 25 to 100 m2/g PH 3 to 6 Compacted density: 400 to 1,200 g/1 They are prepared by dispersing titanium dioxide in water and spray-drying and silanisin. In the silanised form, the granules have the following characteristics: Average particle diameter: 10 to 160.mu.m BET surface ar...

L'invention concerne une installation d'analyse de la teneur en au moins un élément de l'atmosphère d'une enceinte de brasage ou étamage à l'aide d'un alliage métallique, comportant les éléments suivants: - au moins une ligne (1) de prélèvement d'un échantillon de gaz de l'enceinte, - au moins un analyseur (2) apte à analyser ledit élément, - au moins un filtre (3, 4) à coalescence situé sur la li...

The matched nodes provide protection for a failure in the connection between two bidirectional line switched rings. They use a secondary path in case of a primary path failure. The secondary path is set aside in either the working or protection bandwidth of the rings, thus wasting resources. The invention uses inter-ring protection mechanisms which do away with a specifically set aside secondary p...

A device, potentially implantable in a living organism, intended to utilize at least a part of the hydraulic energy generated by the heart (10)-the primary unit-at the natural phases of work when the cavities of the heart (11, 12 and 16, 17) are filed with blood. The device includes at least one secondary unit (24), which is connectable to the cardiovascular system of the organism and arranged to ...

A photocatalytic substance having the properties of an n-type semiconductor is deposited on a surface of a metal base made of a stainless steel or Inconel. When necessary, the hydrogen concentration of the reactor water is increased. A current produced by the photocatalytic substance when the same is irradiated with light or radioactive rays in a nuclear reactor flows through the metal base to red...

It has been found that a cut tree trunk that has a front and a rear major cut surface and possibly also other cut surfaces at which branches have been cut from the trunk can be dried by creating a pressure difference between two of said cut surfaces. Liquid contained in the trunk is tapped-off at a cut surface which is subjected to a pressure that is lower than the pressure at the cut surface to w...
