A hight-pressure composite vessel comprising a casing fabricated through blow-moulding a preform of thermoplastic, a connection pipe fitting. In the connection connection pipe fitting (3) with a retaining collar (7), opposite to a sealing groove (9) designed for an o-ring seal, there is a groove (10) for a seeger to mount a non-detachable collar (11a) of the preform (11) by way of the seeger (10a). A method of manufacturing the high-pressure composite vessel under which the casing of the vessel is fabricated of a perform that is blow-moulded so as to obtain the required dimensions thereof, whereas the preform of a thermoplastic material is fabricated using any technology; and the casing of the vessel is connected with the connection pipe fitting, and the external surface of the vessel re reinforced by a special composite layer. The preform (11) first undergoes a process of controlled crystallization and, then, the ring-shaped groove (11b) is made in the collar (11a) of the preform (11).

A process and a system are provided for controlling an addition of water to a rubber mixture during a mixing cycle in which the mixture is transported as a continuous sheet. The process includes obtaining data for the mixture, including a predetermined water flow rate, a predetermined air flow rate, and a target temperature and a target water content for the mixture; adding water to the continuous sheet during the mixing cycle; detecting an amount of water added at an elapsed time during the mixing cycle; determining, using a detection result, a predicted temperature and a predicted water content for the mixture at an end of the mixing cycle; comparing the target temperature with the predicted temperature, and the target water content with the predicted water content; and, before a next mixing cycle, adjusting an actual water flow rate when a comparison result indicates non-equivalence.

In a blow-molding apparatus, a cooling device and a heating device are each driven by being supplied with electricity of a predetermined voltage from a supply power source. The blow-molding apparatus comprises: a monitoring device configured to constantly monitor fluctuation of the predetermined voltage; and an output automatic control mechanism configured to, in a case where the predetermined voltage monitored by the monitoring device fluctuates beyond a normal range, automatically fluctuate an output of at least one of the heating device and the cooling device to keep the output in a certain range, thereby adjusting at least one of the preform temperature and the ambient temperature to fall within a normal temperature range.

Methods of making oxidation and wear resistant polymeric materials using peroxide cross-linking and high temperature melting process are disclosed. A multiple step procedure for enabling the manufacturing of such material without size limitations is also disclosed.

In the field of tire production, systems and methods utilize a feed belt (150) for directing a rubber mixture from an initial mixing installation (20) toward at least one of two mixing and cooling installations (100, 100). It is possible to selectively carry out monopassage and multipassage rubber production sequences in a common rubber production facility. A tire is formed according to the methods described.
