Abstract:
A garden hose connector arrangement comprising a hose connection portion 1 for accepting the end of a garden hose. The hose connection portion comprises a hose receiving portion 32 in which is disposed a spigot 33 for receiving the end of a length of hose and a clamping arrangement comprising a locking nut 41 and a plurality of deformable claws 52 which surround the spigot 33 and are arranged to be driven into contact with hose H carried on the spigot 33 under action of the locking nut 41. In some embodiments the claws 52 are arranged so that they extend axially inwardly into the hose receiving portion 32. In some embodiments a skirt portion S is provided around the spigot 33 so as to define a hose receiving region R between the skirt portion S and the spigot 33, and an inspection window W is provided in the skirt portion S to enable viewing of a hose end when introduced onto the spigot 33 and into the hose receiving region R.

The root crop harvesting machine comprises an applicator (40) device adapted to apply an agent (52) to the root crop.
Abstract:
The present invention relates to a system of articulated fins for a boat (1) having a hull (2), the system of fins comprising at least two fins (10) having a respective end fastened to an element of the hull (2) of the boat (1), the two fins (10) being situated one on each side of a longitudinal axis of the boat (1), each fin (10) being intended to be completely submerged in a deployed position of the fin, each fin (10) also having a folded position in which the fin (10) is intended to come up against the hull (2) of the boat (1), and each fin (10) having operating means configured to move the fin (10) between the folded position and the deployed position, and vice versa. The fin (10) has a web and a working portion fastened to the web.
Abstract:
The invention relates to an agricultural machine for spraying a phytosanitary liquid over cultivated land, said machine comprising means for moving the machine, a spray boom having at least one arm, a mechanism for inclining the boom and/or at least one of the arms in relation to a frame of the machine and vertically when the machine is on a flat and horizontal surface, and a mechanism for raising/lowering the boom along an axis fixed in relation to the frame of the machine. At least one of the arms is provided with at least one sensor, each sensor measuring a distance between the surface of the land and said sensor or, if necessary, between the crop and the sensor. The control unit is connected to each sensor, provided with a memory for storing information provided by each sensor, and able to control the raising/lowering mechanism according to information stored in the memory.
Abstract:
The invention relates to an agricultural machine for spraying a phytosanitary liquid over a crop planted in a section of land, comprising a spray boom having at least one arm, a mechanism for raising/lowering the boom and, for each arm, a mechanism for inclining the arm, a manual system for controlling each inclining body, and a receiver for communicating with a geolocalisation system and a control unit. Each arm is provided with at least one sensor measuring a distance between said sensor and the surface of the land or vegetation planted in the land, and an element for measuring a datum relating to the incline of the arm. The control unit is connected to each sensor, to the receiver and to the measuring element, is provided with a storage memory, and is able to control each inclining mechanism and the raising/lowering mechanism according to the information stored in the memory.
