A module to be arranged within a hollow vessel for extracting fluid from the hollow vessel is provided, the module comprising a pumping device, at least one filtering device and at least one extension arm which has means enabling connection with the outside of the module. Also provided are a process for fixing such a module inside of a hollow vessel, a hollow vessel comprising such a module and a method for extracting fluid from a hollow vessel wherein the fluid is extracted by such a module.

Module for extracting fluid from a hollow vessel

The invention relates to a process for the manufacture of an article comprising a surface treatment step of at least part of the article in the substantial absence of oxygen; the surface of the article which is to be treated consists of a material which comprises at least one polyolefin and which contains less than 5 mg of oxygen per kg (no account being taken of the optional additives).

Process for the manufacture of an article comprising a surface treatment

The process involves the following steps:

Process for producing, by blow moulding, hollow bodies made of

A portion of a plastic tube (16) heated to a temperature at which stretching induces a molecular orientation, is clamped in a sleeve (14), a fluid under pressure is introduced into the portion of tube and the sleeve is moved along the portion of tube to cause its progressive radial expansion until it makes contact with a mould (1).

Process for the production of tubes of a molecularly oriented plastic

A hollow container of molecularly oriented thermoplastic material having a generally cylindrical form and provided with a base constituted by a series of annular toroidal sections of semicircular cross section and having alternating directions of curvature.

Hollow body made from a thermoplastic

Process for mould release of a hollow plastic body moulded by blowing by means of a nozzle in which after cooling the hollow body and opening the mould, a fluid under pressure is injected into the hollow body through the nozzle in the bottom region of the hollow body. The process may be completed by a mechanical ejector acting from the outside at the neck position of the hollow body after the nozzle has been removed from the mould.

Process for mould release of hollow plastic bodies moulded by blowing by

Apparatus for the continuous production of oriented hollow bodies from a thermoplastic, which includes a device for the production of a continous tubular parison from a thermoplastic. There is also a machine for blowing preforms which is fed with the continuous tubular parison and of which the molds, aligned end to end contiguously on a first rotary carrier, make it possible to produce separate preforms of which the neck is molded to its definitive or ultimate shape. A device is provided for deflashing the neck of the preforms, as is a device for thermal conditioning which brings the preforms to their optimum orientation temperature. A final blowing machine is used which includes a plurality of molds mounted on a second rotary carrier as is a transfer device which bring the preforms from the preform blowing machine to the final blowing machine while causing them to pass successively through the deflashing device and the thermal conditioning device. The preform transfer device includes an endless chain provided with carriers so arranged so as to support the preforms below their neck, which has already been molded.
