The present invention relates to a method and an apparatus for carrying out production logs in an eruptive well. The apparatus is characterised in that it comprises sealing means (9), measuring means designed for processing at least part of the upstream flow and/or of the downstream flow in relation to said sealing means (9), and means (10A, 10B, 19, 33) for controlling the pressure difference on ...

L'invention concerne un film pour paroi en résine de polyoléfine comprenant une résine de polyoléfine, un composé aminé à empêchement stérique, un composé de type hydrotalcite et un agent absorbant les UV qui est utilisé pour constituer les parois d'une serre ou d'un tunnel pour horticulture protégée et qui n'est pas détérioré par un agent soufré inorganique appliqué dans la serre ou dans tunne...

At least one layer of a mono- or multilayered, bioriented film contains as film-forming polymers (A) from 75 to 100 percent of a linear ethylene/alpha-olefin copolymer having a density of from 0.890 g/cm<3> to 0.930 g/cm<3> and (B) from 25 to 0 percent of a high density linear polyethylene having a density of from 0.935 g/cm<3> to 0.960 g/cm<3>. All percentages are based on the total weight of (A)...

A composition which is a uniform blend of 50-90 weight % of a polyamide melt-processable within the temperature range of 180 DEG -210 DEG C. and 50-10 weight % of recovered plasticized polyvinylbutyral, optionally also containing a small amount of an elastomeric ethylene copolymer carrying pendant succinic anhydride groups, has high impact strength and good flexural modulus. The polyamide in thes...

In fluidized catalytic cracking, enhanced efficiency is produced through the use of a spray nozzle having two transversely elongated discharge orifices for effecting fine atomization of liquid hydrocarbon feed as the latter is sprayed from the nozzle. The orifices preferably are inclined so as to produce a converging spray but can be inclined to produce a diverging spray or a substantially flat sp...

The present invention relates to an electric plug comprising a base which carries the electric connection pins, any electric supply cable of which the electric wires are connected to the electric connection pins and comprising a U-shaped linking element fixed by shape complementarity to the base straddling the electric supply cable by being applied against the latter in order to press it against t...

A method and apparatus for verifying that a CAS (Customer Premises Equipment Alerting Signal) detect signal, which indicates the presence of a CAS on a transmission channel, is a valid detect signal, includes structure and process steps for suppressing a signal originating at a local telephone in response to the CAS detect signal. A determination is made whether the CAS detect signal remains in a ...

The present invention provides a eeth-coating liquid comprising a color pigment represented by titanium oxide and a pearl pigment or an extender pigment represented by tricalcium phosphate, dispersed singly or in combination thereof in an alcohol series solvent, mainly ethanol with an N-methacryloylethyl-N,N-dimethylammonium. alpha -N-methylcarboxybetaine.butyl methacrylate copolymer, and an appli...

The clamp includes the sprung strip (6) which may be fixed in a channel (43) in the block (7) or alternatively the two components may be a single piece. The block has a hole for a fixing screw and the strip extends to meet it at a semi-circular cut. The action of screwing down the block tilts it about a recessed edge. An electrical insulator (4) with good thermal conductivity separates the compone...

The prosthesis consists of a socket (1) to receive the femoral head (2), both of which are made from a hard material - a metal or ceramic - and their shape and dimensions are such that a gap (9) is created between them. The gap allows the formation of a laminar film of synovial liquid resulting from the combination of suction and pressure phases in the acetabulum and acting as a lubricant between ...

Disclosed are peptide-based compositions and methods for inhibiting and modulating the actions of CXC intercrine molecules. The antileukinate peptides described inhibit IL-8, GRO and MIP2 beta binding to neutrophils and neutrophil activation. The peptides are particularly advantageous as they inhibit IL-8-induced enzyme release at a 25 fold lower concentration than is required to inhibit chemotax...
