Abstract: A control system for an aircraft includes a hydraulic pump, first hydraulic line, second hydraulic line, a first actuator coupled with a first control surface, a second actuator coupled with a second control surface, and a third actuator coupled with a third control surface. The first control surface and the second control surface are at a distance to each other and symmetrically relative to a symmetry axis. The third control surface is substantially on the symmetry axis, and the first hydraulic line and the second hydraulic line are connected to the hydraulic pump. The first actuator is connected to the first hydraulic line, and the second actuator is connected to the second hydraulic line. The third actuator is connected to the first hydraulic line downstream of the first actuator at a junction point, and the first hydraulic line at least partially includes a larger diameter than the second hydraulic line.

Abstract: A crocodile-type flight control surface comprising an upper foil flap, a lower foil flap, an actuating mechanism which guarantees the rotational displacement of each foil flap about a joint axis, either in the same direction or in different directions, and a locking mechanism alternatively adopting a locking position in which the upper foil flap and the lower foil flap are fixed with respect to each other and an unlocking position in which the upper foil flap and the lower foil flap are free with respect to the other. A crocodile-type flight control surface of this kind is therefore stiffened by the locking mechanism that joins the two foil flaps.

Abstract: An aircraft comprising an air conditioning system for a cabin of the aircraft. The system comprises a mixer unit capable of mixing air that has already circulated in the cabin and fresh air from the engines of the aircraft. The air mixed in this way is then channeled towards the cabin to ventilate it. The aircraft has an airtight bulkhead allowing the cabin to be separated from a rear compartment, in such a manner as to prevent any direct exchange of air between said cabin and said compartment. This airtight bulkhead constitutes a wall delimiting the mixer unit, at least in part.

Abstract: The invention relates to an angle measurement probe on board an aircraft, which comprises a fin, which can move in rotation about an axis, at least one first optical encoder and one second optical encoder, each comprising at least one disk, each disk being fixed at right angles to the central axis and being provided with at least two circular tracks, each track being provided with alternate opaque and transparent zones, means for processing the output signal from each encoder.

Abstract: A subsoil applicator has an upright shank provided with a leading soil-slicing edge and a pair of opposite sides. At the bottom of the shank, a pair of soil lifting wings are provided, presenting a pair of outermost wing edges that diverge rearwardly from the lowermost and forwardmost point of the shank to the rear extremity of the applicator. The wings are generally relatively thin and flat except for a thickened portion across their rear extremity making an upright, rearwardly facing rear wall. A pair of laterally spaced discharge outlets are located in the rear wall and communicate with an internal tubular passage within the shank for delivering substance down into the soil behind the wall as the applicator advances through the soil. The discharge outlets are located in undercut portions of the rear wall, while top, upwardly facing surfaces of the thickened portion are convexly curved to improve soil flow and provide extra protection against premature wear for the internal substance passageways.

Abstract: The present disclosure relates to a cutting tooth for a trencher chain. The tooth includes a base portion aligned along a first plane. The base portion includes structure for allowing the cutting tooth to be connected to the trencher chain. The tooth also includes a distal portion that is generally obliquely aligned with respect to the first plane. A curved transition is located between the distal portion and the base portion. The curved transition curves away from the first plane and at least partially forms a cupped portion that extends from a leading end to a trailing end of the cutting tooth. The tooth also includes a hardened tip positioned at a region of the leading end that is located farthest from the first plane. The leading edge includes more than one effective configuration.

The base portion also includes a recess into which the mounting hardware can fit, to protect the mounting hardware from wear.

Abstract: A vibratory or static plow blade assembly including a blade for opening a slit in the ground, a chute assembly operably attached to the blade for being pulled through the slit in the ground and wherein the chute assembly includes a top opening for allowing an elongated product such as a utility line to be installed in the ground by being inserted into the chute assembly. A product exit point in the chute assembly is disposed below the top opening and internal guides are provided for directing the product to the exit point. At least one nozzle is provided adjacent the exit point for transferring a pressurized material into a desired contact with the product being installed in the ground. Conduits for transferring the pressurized material from above the ground to the nozzles are disposed within the chute assembly.

Abstract: The invention concerns a refrigerating fluid circuit capable of operating in three fluid circulation modes, namely an air conditioning mode whereby the fluid circulates successively in the evaporator where it is evaporated by receiving the heat of the air flow to be treated, in the compressor, in the condenser where it is condensed by yielding the heat to another medium and in a pressure reducing valve; a supplementary heating mode whereby the fluid circulates in gaseous state between the evaporator where it yields heat to the air flow and the compressor, without passing through the condenser, and an inoperative mode whereby the fluid does not circulate in the evaporator. The invention is characterized in that the circulation mode is determined taking into account not only the user's choice but also the possible presence of mist on the windscreen, detected by a sensor, so as to promote demisting while optimizing comfort and energy conservation.

Abstract: Two stop valves, associated with bypass ducts containing energy absorbing devices, enable an adjustable fraction of the hot fluid to be diverted past left and right hand heating radiators, so that any change in the adjustment of the fluid flow in either of the radiators has no effect on the fluid flow in the other radiator.
