Abstract: A device for adjusting the clamping pressure in applicators for clamping terminals onto electrical cables comprising a composite pivot interposed between an actuation hammer and a supporting element to which the tools for clamping the terminal respectively onto the insulation and onto the core of the conductor are slidingly coupled in a mutually parallel arrangement; the thrust of the hammer acts on the heads of the tools, and the pivot is rigidly coupled to the hammer or to the supporting element. The pivot has coaxial threaded regions on which respective wheels are engaged. Screwing/unscrewing of the wheels varies axial distance, with respect to the hammer, of either the tools or only of the insulation clamping tool.

Abstract: A frame particularly usable for in-line or ice skates, comprising two mutually facing approximately vertical walls, transversely to which there are, along the same longitudinal axis, multiple holes for placing the hubs of respective wheels. The frame has, in a transverse cross-section, an oval shape which is closed in the interspace between at least two adjacent wheels.

Abstract: The bag is made from a polyethylene sheet and has a mouth with at least one sheath along its edge, the sheath containing an inextensible ribbon which is graspable from outside through a hole cut in the sheath, in order to close the bag after filling. An elastically extensible ribbon is fastened at its opposite ends to the material of the bag. When the bag is received in a rigid bin with its upper margin overturned over the bin rim, the elastic ribbon is pulled radially, looped and released around the overturn of the bag to clamp it around the bin.

Abstract: A luminaire, of the ceiling-mounted type or of the type for recessed fitting in ceilings and walls for interior lighting, comprising a hollow body which is shaped like a paraboloid and forms a back on an upper part and an opening on a lower part, the body accommodating a light source in its internal cavity; the internal surface of the body is divided into sectors which form receptacles that can be engaged detachably by a plurality of reflective laminar elements in order to form various hues, chromatic compositions and/or light distributions.

Abstract: An apparatus for manufacturing threaded caps comprises a plurality of compression molding assemblies which are arranged on a rotating carousel and comprise an upper male mold half and a lower female mold half. The male mold half comprises a tubular element, a sleeve guided coaxially to said tubular element, and a punch guided in the tubular element and having a helical slot for forming the thread of the cap. The punch enters the female mold half and produces, together with it, the cap through compression of a dose of plastic material deposited in the female mold half. After the spacing of the punch from the female mold half, the removal of the cap from the punch occurs by way of a removal device, which comprises a ring gear associated with the sleeve and provided with a collar in sliding contact on the punch, a rod which can slide axially in a seat of the carousel and supports a gear meshing with the ring gear and connected to a motor drive mechanism.

Abstract: An actuation and control device for opening and/or closing high- and medium-voltage circuit breakers having at least one fixed contact and at least one moving contact, comprising actuation means which are operatively connected to the moving contact and supply the energy for performing the opening/closure movement, the particularity of which consists of the fact that the actuation means comprise a servomotor, an electronic control and power supply unit, and elements for transmitting motion, and that the actuation means and/or the coupling between the fixed contact and the moving contact are such as to achieve a desired speed of the moving contact at the instant in which it separates from the fixed contact.
