A procedure to determine the inflow of oil and/or gas from an oil and/or gas reservoir under the surface of the Earth into a wellbore in the reservoir. Traceable material with different identifying characteristics, e.g. different radioactive isotopes, is separately inserted or arranged in connection with different zones, places or regions along the length of the well. During production of oil and/...

A unitary plastic appliance door is produced by thermoforming an outer door panel and an inner door liner and joining them together in a unitary apparatus. The inner door liner is formed of sheet plastic on a male mold member and is then positioned over a female mold member mounted alongside the male mold member. The outer door panel is formed from a second sheet of plastic in the female mold memb...

For future digital television broadcasting and the interactive communications services associated therewith, video data must be greatly reduced in terms of their volume of data by means of suitable coding devices. One coding method provided for this is the MPEG2 standard. If, during the coding, a change in the picture scene occurs within successive Groups of Pictures, no rational basis for the pre...

A fibre product manufactured of flax or a corresponding stem fibre plant constitutes a structural element containing both actual fibres (1) of the stalk and wood splinters or shives (2) originating from the same plant raw material and incorporated in the product by crushing the structure of the stalk to a sufficient degree. The product can be a pressed-to-shape structural element or a porous produ...

Peptide ligands which bind to thrombin and prothrombin are disclosed. The sequences of these peptides are Gln-Leu-Trp-Gly-Ser-His, Arg-Gln-Leu-Trp-Gly-Ser-His, His-Gln-Leu-Trp-Gly-Ser-His, and Tyr-Phe-Pro-Gly-Pro-Tyr-Leu. The preferred peptides have the sequence Gln-Leu-Trp-Gly-Ser-His or Tyr-Phe-Pro-Gly-Pro-Tyr-Leu. A method of using these peptides in an affinity chromatography process to purify ...

A system for separation of fluids and drill cuttings received-from a borehole during an under-balanced drilling procedure. The system is designed to cope with significantly varied pressures and flow rates, particularly in relation to gas content of drill fluids returned to the surface during the drilling process in a production zones and to provide effective separation and to reduce the detrimenta...

Apparatus and methods are presented for forming coils that are used for the winding of a stator of a dynamo-electric machine and for inserting those coils into slots of the stator. The apparatus includes a plurality of coiling stations that operate in a synchronously staggered manner and an inserting station. The coiling and inserting stations are equiangularly spaced apart from each other around ...

Apparatus and methods are presented for forming and inserting multi-lobed coils into slots of a stator for an alternator, the coils constituting the winding of the stator. The apparatus includes first and second coiling stations and a coil inserting station. The first and second coiling stations form and load, either sequentially or independently, a coil-inserting tool with first and second multi-...

This is a surgical device. In particular, it is a guidewire having a metalli c core and specifically having a distal section comprising a number of fibers. Thefibered distal tip is shapeable using, e.g., steam o r hot air, and causes much less trauma than would a coil of similar capabilities.; This is a surgical device. In particular, it is a guidewire having a metallic core and specifically havi...

Ce support de disque de polissage est constitué d'un corps (1) ayant un trou de centrage (4) au centre de l'une des faces et un trou d'entraînement (5) excentré dans cette même face. Un revêtement (6) en matière plus tendre que celle du corps (1) est appliqué sur l'autre face (3).; A polishing disc support, designed to receive a layer of a fine abrasive paper or cloth used e.g. for finishing elect...

An arrangement in connection with a spooler which is arranged to wind a reel arranged in the spooler when a fibrous or a ribbon-like material is wound off the reel for a treatment process of the fibre or the ribbon or when a fibrous or a ribbon-like material is wound on the reel, for preventing tangling. The arrangement includes a gripping and cutting mechanism that rotates along with the reel and...

The invention provides a screwscrip comprising a holding strap carrying scre ws with the holding strap being curved in a plane containing the axes of all th e screws.

The solar panel has a framework, a reflector, an insulating layer and a fluid conducting system. The solar panel is coupled to an accumulator (8) and a conduit system (13) for distribution of the recovered energy. The accumulator stores so-called excess energy, especially during the Summer period and light-intensive days, for further distribution during the Autumn and Winter months. - It can prefe...

An air intake manifold for use with an internal combustion engine is provided with a labyrinth configuration in order to reduce the amount of space consumed by the manifold. The manifold is preferably made from a plastic material for reducing the weight of the manifold and for providing an inexpensive and relatively simple molding process.

A system and method for modification of the visual characteristics of digital 3D objects includes a shading buffer wherein parameters relating to the visual characteristics of a rendered 3D object are stored. When a texture applied to th e 3D object is selected for modification, a pre-rendering step is performed and a shading bu ffer constructed. The shading buffer includes pre-computed components...

Audiovisual programs are transmitted over a low-bandwidth network in a compressed form in which the number of video frames has been reduced by selecting "significant" frames. The user sees a series of still images accompanying an apparently full audio channel. If a particular frame is advertising, then the user is identified, and depending on the user's demographic or psychographic profile, anadve...

An attenuator capable of controllably attenuating at least two wavelengths o f light is configured to have an optical waveguide section having at least two Bragg gratings disposed therein in series. The Bragg gratings have a sloped reflectivity response within a predetermined wavelength range. The sloped response is a function of refractive index variations within each of the grating elements. By ...
