Abstract: An irrigation device includes a hollow element having an at least partially closable opening and having a substantially open and optionally closable annular shape, one end of the hollow element having, at the opening, an outward radial extension to form a counter-curve defining a guiding section with a concavity different from the concavity of the remaining annular element. The device further includes a tubular element inserted or insertable in the hollow part of the annular element and provided with a plurality of openings to enable the dripping of a liquid when such liquid is introduced at one end of the tubular element, the opposite end being closed or closable with a plug or connectable to the first end with a connector.

Abstract: A sprinkler pipe includes an elongated pipe element having at least one longitudinal row of dispensing holes distributed at predefined distances, each of the holes communicating with a drip unit provided inside the pipe and having at least one inlet communicating with the inside of the pipe and at least one outlet communicating with at least one dispensing hole.

Abstract: A device for holding a bend area of an elongated flexible element, such as an electric cable, a rope, a plastic tube or the like has two through-holes placed side by side in a shaped body. At least one of the two holes has a side opening extending to the corresponding peripheral edge of the shaped body, thereby making the hole accessible from the outside.

Abstract: A self-compensated, adjustable fluid emitter includes a casing externally delimiting a volume, which is divided into a first chamber and into a second chamber by a fixed membrane that can be elastically deformed. An inlet communicates with the first chamber and an outlet communicating with the second chamber, causing the first and the second chambers to be in communication one with the other through a communicating duct. In operation, the membrane becomes deformed such that at least a portion thereof changes its position with respect to the outlet, modifying the flow rate of the fluid through the outlet depending on the pressure difference. Therefore, the flow rate of the fluid through the outlet is controlled and kept constant by the membrane in spite of changes in fluid pressure at least at the inlet or the outlet.

Abstract: Irrigation pipe including a pipe having at least a longitudinal row of delivery holes arranged at predetermined distances and communicating with a dripping unit provided inside the pipe, and further having an inlet communicating with the inside of the pipe and an outlet communicating with at least one delivery hole. The inlets or outlets of some or all of the dripping units communicate with the inner space of the pipe or with some or all of the delivery holes through an inlet collecting channel or an outlet collecting channel or segments thereof.

Abstract: The invention relates to a self-compensating drip irrigation emitter. A plurality of novel embodiments are provided, wherein the emitter of the invention is capable of always supplying a substantially constant flow within a range of pressures of a fluid flowing in a pipe (3), from very low to very high pressures. Furthermore, the emitter of the invention has such characteristics as to prevent any accidental and undesired clogging thereof by sediments or debris.

Abstract: The invention relates to a method for fabricating a drip irrigation pipe, comprising a pipe (5) wherein a plurality of dripping elements (4) are bound, communicating with the outside through holes formed in the pipe wall. The method according to the invention provides that the pipe (5) is extruded and the individual dripping elements (4) are bound therein by consecutively feeding the dripping elements (4) inside the pipe through the extruding head (1). The speed of the dripping elements (4) is higher than that of the pipe upon extrusion at least in the area of first contact between the pipe and the dripping elements (4). The invention also relates to a plant for implementing said method.

Abstract: A pipe fitting element comprises a tubular fit-in sleeve (1) which can be fitted into an end of a pipe (2) to be connected, and a clamping ring nut (10), coaxial to the sleeve (1). The pipe (2) is arranged to be clamped by tightening the ring nut (10) on the sleeve (1) and translating it towards the pipe (2) while drawing two clamping surfaces (5, 13) mutually closer. One of the surfaces is situated on the outer surface of the sleeve (1) and the other situated on the inner surface of the ring nut (10). These clamping surfaces (5, 13) consist of progressive widening (105, 113) of the outside diameter of the sleeve (1) and of the inside diameter of the end of the ring nut (10) turned towards the pipe (2). A pipe joint, which has at each end a pipe fitting element of the above described type is also provided.

Abstract: Threaded connection device for pipes including a cylindrical sleeve having, at both its ends, fasteners for the connection with a flexible pipe, two internally threaded rings each one screwing on one end of the sleeve. These said rings have a circular rim for the seaming and the compression of the pipe around the sleeve fasteners. The sleeve, in connection with the ring thread, has a thread part having a pitch multiple as to the thread pitch of the ring itself.

Abstract: A gunslight aiming device which employs various methods of image transmission to allow the user of a weapon to be positioned at various locations spaced from the weapon thereby permitting a wider variety firing positions, faster aiming between firing, and accurate aiming regardless of the relationship between head and aiming eye(s) and weapon. The arrangement provides a transmission mechanism preferably in the form of a flexible fiber optic cable which is coupled to a standard optical sight by a coupling mechanism which conditions the signal for transmission by the flexible optic trunk. The image is again conditioned at a second coupling arrangement for viewing by the user.
