A method for plugging wells for use in connection with extraction of a fluid. Above a leakage site in the well, from which the fluid flows into the well from a subsurface formation surrounding the well, there is a set a seal (20), which seals the well, and on the bottom of which is a sensor device (22) for measuring well data. On the top of the seal (20) is a connecting part (24) which is connecte...

A method is disclosed for the use of a modified latex making it possible to provide a combination of hydrogene bonds and covalent bonds in fibrous products. A softener product is added to the binder solution before its application onto the fibrous product. The softener is a natural latex added to a latex binder contained in a water suspension. It has surprisingly shown that a product manufactured ...

Monoaxially oriented polypropylene is coated with a pigmented polymer dispersion which imparts good print quality, ink adhesion, and smudge resistance to the ultimate biaxially oriented film.

The present invention relates to a novel ethylene/pentene-1 copolymer whose molded film has a good balance between impact resistance and tear properties and high transparency, also is prominently reduced in a variation of the transparency even after subjected to a heat treatment, and further shows high blocking resistance, provided that the copolymer fulfills specific requisites. The invention als...

A monitoring and safety system for air-operated parking brakes and foot brakes on a vehicle employs electric contacts to provide alarms when movement of the actuators occurs in a manner indicative of failure or malfunction in the actuators or in the brakes themselves. The system also includes a number of air pressure sensors for monitoring and alarm functions. In addition, parking brake air pressu...

A handle with simplified safety actuation for doors of trucks, trailers or the like, comprising: a first box-like element (2), which is provided with means for fixing to the door and is provided with an engagement tooth (5) rigidly coupled to the bottom (3); a second box-like element (6), which is articulated along one side of the first element (2) and has means for the articulation of two seconda...

The present invention relates to a system and a procedure for distribution of a service request in a computer system based on a client-server architecture and comprising at least one client (1), which sends service requests to servers (2<1>, 2<2>, ..., 2); one or more servers (2<1>, 2<2>, ..., 2), which provide callable services for the client (1); and middleware means (3). According to the ...

A dielectric oil which is a mixture of benzyltoluenes and of benzylxylenes. This oil can be prepared by a Friedel and Crafts condensation of benzyl chloride with a mixture of toluene and xylene. The dielectric strength (breakdown voltage) of this oil has been measured.

Light brickwork mortar of at least class LM 21, especially in the form of a works fresh mortar product or a works dry mortar product which can be pumped after water addition, contains 30-75 (preferably 30-50) wt.% hydraulic binder in the form of cement, 5-15 wt.% hydraulic or latent hydraulic binder component, 5-60 (preferably 40-60) wt.% light aggregate in the form of round expanded clay granules...

This invention relates to a laminated material, more precisely to a thermobonded nonwoven material made from polyolefin fibers, and laminated with a thermoplastic film. According to this invention the properties of the laminate are improved by using a skin-core polyolefin fiber in the manufacturing of the nonwoven fabric. The laminate can be used in hygiene and medical applications, for example as...

Method and structure for collecting statistics for quantifying locality of data and thus selecting elements to be cached, and then calculating the overall cache hit rate as a function of cached elements. LRU stack distance has a straight-forward probabilistic interpretation and is part of statistics to quantify locality of data for each element considered for caching. Request rates for additional ...
