Abstract:
Variable nozzle (10) for a gas turbine fixed to a shaft (11) equipped with a pressurized upper surface (12) and a depressurized lower surface opposite to the upper surface (12), the variable nozzle comprises a series of substantially "C"-shaped sections, each having a first rounded end and a second rounded end each section of the series of sections also having the concavity facing upwards with respect to a base (90) and arranged one after another continuously, in the direction of an axis of the shaft (11) along a curved line (60), the at least second degree curved line (60) lies on a surface (70) having an axis orthogonal to the axis of the shaft (11) and also tilted with respect to the base (90) by an angle (80).
Abstract:
Control and regulation system of a combustion unit (10) of the type comprising a combustion chamber (11) and a catalyst (40), the control and regulation system comprising: - an acquisition device of signals proportional to functioning parameters characteristic of the functioning state of the combustion unit (10 ), an electronic data processing unit (30) connected to the signal acquisition device from which it receives signals, a control and regulation program associated with said electronic data processing unit (30), a first fuel distribution valve (20), a second air distribution valve (21), a data base associated with said electronic data processing unit (30), the electronic data processing unit (30) receives signals from the signal acquisition device, processes them and regulates the opening of the first valve (20) and second valve (21) to minimize the polluting emissions of CO and Nox of the combustion unit (10).
Abstract:
The present invention relates to a rodenticidal composition in the form of fresh paste for enticing mice and rats wherein the flour used is mainly of a vegetable origin and the fatty matter incorporated essentially consists of palm oil.
Abstract:
An improved assembly (110) consisting of internal casing (112) and support device (114) for nozzles in a gas turbine stage, these nozzles being grouped together in sectors and each of these sectors being connected externally to an external casing of the gas turbine by means of the support device (114), this support device (114) being kept in position by the internal casing (112), there also being formed first cooling holes (122) on the internal casing (112) and second cooling holes (124) on the support device (114); the first cooling holes (122) of the internal casing (112) have an extension substantially parallel to the axis of the gas turbine.
Abstract:
An aqueous composition for the chemical removal of metallic surfacing present on the blades of turbines, preferably gas turbines, comprises at least hexafluorosilicic acid and phosphoric acid.
Abstract:
A reduced-wear sealing element (10, 30, 40, 50, 60), in particular for cylinders and pistons for reciprocating compressors, made at least in part from a self-lubricating plastics material; such a material comprises a wear-resistant polymer matrix (11), in which are dispersed microcapsules (12) containing a lubricating agent.
Abstract:
The present invention relates to a method for producing a self-lubricating plastics material in which a polymer material is first cooled to cryogenic temperatures with liquid nitrogen to give rise to a crumbly, frozen polymer material which, once crushed, is mixed with microcapsules containing a lubricating fluid before then being compression moulded to yield a plastics material with lubricating microcapsules incorporated into the polymer matrix. The resultant self-lubricating plastics material is suitable for the production of sealing elements for reciprocating compressors.
Abstract:
Medical surgery, and in particular, dental surgery, comprising new or column type equipment that contain all the instruments needed by the dentist, and that can be moved so that work conditions are as ergonomic as possible. The column contains all the energy sources necessary for instrument function. These instruments are also equipped with rapid connection systems to the supply sources to ensure the sterility of the part of the instrument with which the dentist and each patient are in contact. This system is designed so that the doctor can work with perfectly sterile instruments that remain sterile for each patient and for the whole work life in order to eliminate the risk of transferred infection.
Abstract:
A system for selecting the stitch forming organs for textile machines; in particular for circular machines for knitwear, contemplates software management such as to update the status of each individual lever (28) of an activator (20), as well as in predetermined time intervals corresponding to the angular positions that occur every K needles (10) or sinkers (26), where K is the number of levers (28) in line of the activator (20), also in other time intervals corresponding to intermediate angular positions includes between 1 and K; the correct value of these angular positions is determined by the profile of the lever (28) of the activator (20).
