- Méthode et dispositif pour évaluer dans le même temps et avec le même appareillage, des paramètres physiques tels que la perméabilité absolue et la porosité, de fragments extraits d'un milieu poreux naturel ou artificiel fragmenté. - On mesure la porosité des fragments au moyen de tests de pression à l'hélium ou tout autre gaz, suivant un protocole connu en soi. L'enceinte qui les contient, est ...

A method and a control system for positioning a mine vehicle. Measurement of a distance travelled by the mine vehicle is based on monitoring rotation of a wheel. In the invention, an error caused in the distance measurement by wear of the wheel is compensated for automatically when the distance value obtained from monitoring is corrected by a correction factor. The value of the correction factor i...

A method of initializing the position and direction of a mining vehicle, and a mining vehicle. An environmental model and route points are stored in a control system of the vehicle. The environment of the vehicle is scanned, and scanned points are generated based on obstacles observed. The control system is arranged to determine coordinates of the scanned points by using the position of the route ...

A method for automatically guiding a mining machine ( 14 ) provided with a route determined as successive route determined as successive route points in the mine. In the method, data relating to the successive points are used for determining additional route between the successive route points for guiding the mining machine ( 14 ).

A mine vehicle and a method of preventing a mine vehicle from colliding. The mine vehicle (1) includes at least one scanner (13, 14) to scan the environment in front of the vehicle. On the basis of the scanning, an obstacle-free route is determined whose outermost points in a sideward direction are stored as memory points (21). At least one sideward safe area (15b) has been predetermined around th...

A method for automatically controlling a mining machine. In the method a route is determined for a mining machine (14) in the form of successive, interconnected segments in a coordinate system fixed in a relation to the mine, the segments in turn being determined as successive points located at a distance from one another. The location of each point is determined in the coordinate system fixed in ...

The invention relates to a method for manufacturing a heat-resistant and heat-insulating structure. According to the invention, a dry matter composition is formed containing 10-60 w-% fine fraction the particle size of which is < 0.1 mm and which includes a dry component that binds air bubbles, and 40-90 w-% coarse fraction the particle size of which is > 0.1 mm, and 5-20 w-% water is mixed into t...

The invention relates to an adhesive comprising (a) 25 to 45% by weight of a polymer composed of (a1) from 30 to 60% by weight of acrylic acid, from 30 to 60% by weight of butyl acrylate, from 0 to 40% by weight of ethylhexyl acrylate and from 0 to 10% by weight of a vinyl monomer; or (a2) from 50 to 90% by weight of acrylic acid, from 10 to 50% by weight of butyl acrylate and from 0 to 10% by wei...

The invention provides a liquid container for storing liquid to be supplied to a liquid consuming apparatus. The liquid container is constructed such that pressurized fluid is sent to its inside so that the liquid in the inside is delivered to the outside. The liquid container includes a container body which stores the liquid in its inside. The container body includes a pressurized fluid introduct...

A method for reducing the formation of combustion chamber deposits in an engine using a friction modifier for combustible fuels is provided. The friction modifier is prepared by combining a saturated carboxylic acid and an alkylated or alkoxylated amine. The particular selection of friction modifier enables a stable additive concentrate to be formulated providing a significant decrease in CCD with...

An electrode material for a lithium secondary battery having alloy particles including a silicon phase and at least one intermetallic compound containing at least one element selected from the group consisting of aluminum, zinc, indium, antimony, bismuth and lead, which is dispersed in the silicon phase, wherein the alloy particles have an average particle diameter of 0.02 µm to 5 µm, the crystall...

Methods, systems, and computer program products that reduce buffer requirements in a messaging system so that the messaging system can send or receive relatively larger messages using a given buffer size. Message handlers are provided, each identifying a corresponding processing operation to perform on a message object having a streamed portion with a stream oriented interface. Pipelines comprisin...

A cover for a child seat in the form of a pad with slots through the pad that facilitate simple removal and reinstallation of the cover. Some of the slats accommodate the seat safety harness and merge with side slots that are held closed by mating separable fastening elements. The side slots extend at least partially along the junction between the backrest portion and the side bolster portions of ...

Ep-CAM is a tumor-associated antigen overexpressed in many solid tumors but shows limited expression in normal epithelial tissues. To exploit this favorable expression pattern for targeted cancer therapy an Ep-CAM-specific recombinant immunotoxin was developed and its antitumor activity investigated. The immunotoxin 4D5MOCB-ETA was developed by genetically fusing a truncated form of ETA (ETA252-60...
