The invention relates to a yaw control device for an aircraft fitted with a supersonic nozzle having a rectangular or flat section comprising a supersonic throat extended by a diverging portion in which supersonic flow occurs. In order to enable the aircraft to be controlled in yaw in the absence of a vertical fin, the device of the invention makes use of jet control surfaces in the form of airfoils disposed in the diverging portion of the nozzle. The control surfaces are movable about respective pivot axes in order to generate a lateral force when in a deflected position, so as to enable the aircraft to turn about its yaw axis.

A solar panel interconnection system in which electrical interconnection distance is minimized irrespective of one of landscape or portrait panel orientation includes a first solar panel having first diagonally opposed corners, a first edge, a second edge and a tap to provide electrical connectivity thereto, and a second solar panel having second diagonally opposed corners, a first edge, a second edge and a tap to provide electrical connectivity thereto. The first edge and the second edge of the first solar panel extend from one of the first diagonally opposed corners and the tap on the first solar panel is disposed at the same corner thereof. The first edge and the second edge of the second solar panel extend from one of the second diagonally opposed corners and the tap on the second solar panel is disposed at the same corner thereof. The first solar panel and the second solar panel are disposed with either the first edge of each facing each other, such as in a landscape orientation, or the second edge of each facing each other, such as in a portrait orientation. In either event, the tap on each panel will be proximate each other to minimize electrical interconnection distance.

An engine unit for an aircraft including an engine, a device for hooking the engine, and a nacelle surrounding the engine and provided with fan cowls, the device for hooking including a rigid structure and a front aerodynamic structure whereon the fan cowls are articulated, the front aerodynamic structure including a cradle with a rear mechanism of hooking mounted on the rigid structure. The cradle also includes a front mechanism of hooking mounted on an air inlet of the nacelle.

The invention is directed toward an optical fiber that reduces the cladding mode coupling loss (CMCL) therein. The fiber includes a core, a cladding concentrically surrounding the core, and at least one lossy region concentrically surrounding the core. The lossy region is disposed within the cladding and is slightly displaced radially from the core.

A process for the production of a frozen vegetable or part thereof, wherein said process comprises the steps: (i) subjecting a vegetable or part thereof to a firming treatment selected from: a) immersing the vegetable or part thereof in a solution of a calcium salt. b) heating the vegetable or part thereof to a temperature in the range 50 to 70° C., and c) a combination of a) and b); (ii) under-cooling to a core temperature of less than or equal to -5° C.; (iii) reducing the temperature to less than or equal to -18° C. The frozen vegetables, when thawed, possess a texture and appearance which closely resembles that of fresh vegetables.

A method of partitioning involves a predetermined layout of parts that are to be cut out from a sheet of flexible material by moving at least one cutter tool along two directions in at least two distinct and determined cutting windows along which the material is advanced in succession. Starting from a predetermined layout of the parts in the material, the method comprises: automatically creating mutually distinct groups of parts by allocating each part to a single group of parts as a function of its geometrical position, each group of parts being associated, for cutting out, with a single cutter tool and with a single cutting window; and applying spacings between the various groups of parts.

The invention relates to a method and a device for the coating of running substrates (25) moving along a run direction through a treatment zone (6), in which the vapour of a coating material is generated in a chamber (5), this vapour passing through a treatment aperture towards the treatment zone (6) where the coating material condenses on the surface of the substrates (25). The vapour flow through the treatment aperture is controlled by adjusting the extent to which the treatment aperture is shut off by at least one shutter (13), between an open position, in which said vapour flows through the treatment aperture towards the treatment zone (6), and a closed position, in which the vapour is prevented from flowing towards the treatment zone (6) through the treatment aperture.

A rigid trash receptacle with retractable strap for receiving a trash can liner and securing it to the upper rim of a rigid trash receptacle in order to keep the trash can liner from falling into the rigid trash receptacle when it is being filled. Such a securing system includes a rigid trash receptacle with a protruding upper rim, a retractable strap and a rigid hook on the protruding end of a strap that is contained in a strap retractor mechanism which the strap can be spooled out of and retracted back into with the help of a torsion spring, and a pointed stake protruding from the outside of the rigid trash receptacle that is mounted close to the upper rim of the rigid trash receptacle enabling the retractable strap to wrap around the upper rim of the rigid trash receptacle and eventually be hooked onto the pointed stake pinning the open end of the trash can liner to the upper rim of the trash can.

The invention is directed to a process for recovering/purifying (meth)acrylic acid which does not use azeotropic solvent and is based on the use of two columns for purifying a reaction mixture comprising (meth)acrylic acid. The process according to the invention includes a dry vacuum pump condensation system, which makes it possible to reduce the amount of final aqueous discharges.

The invention relates to a method for reducing drastically and/or eliminating aflatoxins in feeds, thus enabling to produce meat and milk free from aflatoxins, by using specific lactic bacteria eliminating the presence of molds from feeds for cattle nutrition and the subsequent aflatoxin contamination of meats, milk and dairy products; the invention also provides a composition suitable to said purpose.

The invention relates to a device (1) for supplying at least one molding device (2) with a polymerizable mixture of at least two reactants.

According to the invention, said supply device comprises: a buffer tank (10) suitable for receiving said polymerizable mixture via an inlet (101) of said buffer tank, a supply circuit (11), looped with said buffer tank, to convey the polymerizable mixture to an inlet (110) of said at least one molding device and including, beyond said inlet of the molding device, a return pipe (115) connected to the inlet of the buffer tank for sending a portion of the polymerizable mixture from said return pipe, and a filling pipe (42) of said buffer tank, connected to said inlet of said buffer tank, separate from the return pipe, wherein said buffer tank is also suitable for receiving said polymerizable mixture or at least one of said reactants from said filling pipe.

The invention relates to a process for purifying an aqueous solution comprising ethanol, acetaldehyde and diethylacetal comprising: a step A) of countercurrent liquid-liquid extraction comprising an extraction section supplied at the top by said aqueous solution as a mixture with at least one fraction of the water/ethanol/acetaldehyde raffinate resulting from the back extraction step B), and at the bottom by an extraction solvent, and producing an extract at the top and a purified feedstock at the bottom; —a step B) of countercurrent liquid-liquid back extraction comprising a back extraction section supplied at the top by an acidic aqueous solution, the pH of which is between 0.5 and 5, and at the bottom by the extract resulting from step A), and producing an extract at the top and a water/ethanol/acetaldehyde raffinate at the bottom.
