Abstract: There is described a shower spray device including a lower plate with a plurality of nozzles and an upper plate with an inlet for the water supply. An elastic sealing element is interposed between the two plates to delimit therewith a chamber for distributing water to the nozzles. To maintain the correct pressure of the two plates, clamping screws are used also having the function of delivery nozzles, i.e. screws formed by threaded pins having an axial duct, with an outlet open towards the outside to allow water delivery, and at least one transverse duct to place the distribution chamber in fluid communication with the axial duct for water delivery.

Abstract: A shower spray device is described in which the side wall of the water distribution chamber consists of a sealing element.

Abstract: The invention refers to the field of self-locking safety disposable syringes with needle protection after use. The syringe comprises a hollow barrel (1) ending on its lower side with an internal seat (2) adapted to receive a hub (3) carrying a cannula (4). A hollow driving rod (5) adapted to house a spring (6) is inserted in the hollow barrel. Such rod is closed at its lower end by an extracting element (8) that can slide into the hollow driving rod. The extracting element has an annular notch (9) in which a sealing ring rubber gasket (10) is housed that seals the internal wall of the hollow barrel (1). The extracting element (8) with related sealing ring gasket (10) form a liquid sucking and compressing plunger.

Abstract: An apparatus for processing wire or rods includes a plurality of driven fixed rollers for feeding the wire or rod through the apparatus, each fixed roller having an axis of rotation normal to the central access of the wire rod. A plurality of adjustable rollers is provided for engaging the wire rod and imparting a plastic deformation thereto. Each adjustable roller has an axis of rotation and the adjustable rollers are offset from the fixed rollers. A device is provided for moving the adjustable rollers from a position out of engagement with the wire rod to a position engaging the wire rod. A device is also provided for independently adjusting the adjustable rollers so that the planes defined by the axis of rotation of the adjustable rollers are set at an adjustable angle to the central axis of the wire rod so that a desired torsion can be applied to the wire rod. A wire bending device is also provided for bending the wire or rod, and a cutter is provided for cutting the wire or rod.
