A package has a container formed with a dispensing opening and a supply of nonwoven disinfecting wipes in the container. The wipes are made of fibers containing lignin and impregnated with a disinfectant solution having at least two liquid components. A lignin content of the nonwoven wipes is between 0.02 g/m2 and 1 g/m2 and/or the disinfectant solution contains a dye. Thus if at least a part of one of the wipes is overexposed to air, it will change color as oxidized lignin and/or dye collects in it.
摘要:
The invention relates to a method for examining the resistance of a connection between two bodies, whereby one of the bodies only has a small mass. A correspondingly directed force is exerted upon the connection until disconnection thereof. The force used is the centrifugal force which acts at a distance from a rotational axis in a concentric manner about said rotated connection. Said method is particularly advantageous if the body having a small mass is a coating which is applied to the other body. In order to obtain a sufficiently high centrifugal force, an examining stamp is applied to the body having the small mass and/or the coating on the side oriented away from the connection. The adhesion between the body and/or the coating and the examining stamp is greater than between both of the bodies and/or the coating and the other body.
摘要:
An apparatus for three-dimensional single-channel seismic measurements, wherein at least one seismic source (1; 1′, 1″) and hydrophone devices (2) are towed behind a vessel (3), and wherein a pair of deflectors (4, 5) are used that are submerged in the sea (6) and which, as the vessel moves, seek to move in a direction transverse to the vessel's direction of travel. Fastened between the deflectors (4, 5) is a wire (7) which limits the spacing between the deflectors (4, 5). Along the wire (7) there are also mounted thereon hydrophone devices (2) which in relation to the spacing (d3) of the devices have a short lengthwise extent (d4). The devices (2) are connected together by a hydrophone signal cable (8). An additional signal cable (12) connects the cable (8) to the signal processing equipment (10) on the vessel (3). The seismic source (1) may be connected to signal equipment (10) on the vessel (3) and located in an area between the vessel (3) and said wire (7), or at least one of the deflectors (4, 5) may be equipped with a seismic source (1, 1′, 1″).
