The invention concerns a method for treating bivalves such as oysters (4), clams and the like, consisting in cracking the bivalve open during or at the end of the culture cycle, by soaking them in an appropriate solution, then in inserting between the two valves means for sectioning the adductor, said means capable of being actuated outside the bivalve. The invention is characterised in that it co...

A method and apparatus for the production of iron carbide in a shaft furnace, by reacting a carbon containing reducing gas as the process gas with particulate metal oxide material for an extended residence time at low temperature.

The mold employs an insert with two types of section, one forming a support, another keying with it. When positioned on a section of the tire mold, the support projects from it. When located for molding, each key is assembled in its support. The mold is closed and the tread is molded. The keys are then extracted from the support(s). Finally, mold sections are retracted to the open position to extr...

The container has a top (E) with an inner duct (1) linked to the container at one end and to an outlet (10) at the other. The duct is at least partially closed by an insert (2) with a selective porosity which permits a controlled flow of the product outwards on the one hand and a filtration of indrawn air on the other, holding back contaminants and/or biological pollutants. The top is covered by a...

The system consists in the following formula: CaO + H2O = Ca(OH)2 + 15,100cal. with an adequate addition of quantity of contaminated toxic and noxious waters also from metals in solution, with acceptable costs on the market and without contaminated residual reworks as the contaminated waters are transformed by liquids in insoluble solids incorporated in the lime without causing damage to the ambie...

A device (6) which is activated by a user (1) and connects the user's unit (8) to a computer network (4) by means of a server (5) of a service provider which can also be a network access provider. The connection by means of the device (6) allows one to connect to the network (4) while nondeletable messages, such as advertising, are sent, by means of the software of the server (5) of the service pr...

The invention relates to a method for forming a simulation model of two-phase flow in pipelines and notably in pipelines carrying hydrocarbons. The method comprises solving mass conservation equations for each of the phases and an equation of momentum conservation of the flow, while complying with closing relations. An explicit solution is used on slow waves (corresponding to the propagation of a ...

The invention provides a model representative of steady and transient flows, in a pipe, of a mixture of multiphase fluids, which takes account a set of variables defining the properties of the fluids and of the flow modes having separate phases which are dispersed and intermittent, and the dimensions and slope of the pipes. The modeled quantities characterizing the flow are determined by solving a...

A power train in a motor vehicle has an automated clutch which is operated by a control unit by way of an actuator. The control unit receives signals from various parts of the engine, from the brake or brakes and from the transmission; such signals are processed and transmitted to the clutch by way of the actuator so that, when the vehicle is to carry out a crawling movement, the torque being tran...

Torque which is being transmitted by a clutch in the power train of a motor vehicle is regulated in response to processed signals from a control unit which receives signals denoting the driver's desire concerning the acceleration of the vehicle as well as numerous other variables including the position of the gas pedal, the RPM of the engine, the input and/or the output RPM of the transmission and...

The procedure uses a thermal engine (7) and a gearbox mechanism (8) which responds to the position of the accelerator pedal. The engine and gearbox receive respectively a signal of load ( alpha ) and a signal of transmission ( OMICRON ). These are established on the base of single signal of power (P) established from the position of the accelerator pedal (p);

A transmission for a vehicle has input and output shafts, a layshaft and a set of meshing gears and control clutches. At least one of the control clutches is designed to transmit high torque and its action is linked to the drive clutch. The load clutch is operated when the drive clutch is fully, or partially engaged and effectively provides a gear-change under torque. The drive clutch can be a hyd...

The detection monitors instantaneous road conditions by measuring a parameter that can indicate presence or absence of slippery road conditions. This information is recorded to record the change in conditions over time, and a value produced from this which is compared to a threshold value. The result of the comparison decides whether or not the current conditions indicate a slippery surface.; <...
