The tripod includes a spider for the articulation of the legs and a support mounted in the spider with a first seat coaxial with the principal axis of the tripod and a second seat with an axis substantially perpendicular to the first seat so that a column of the tripod can be housed alternatively and removably either in the first seat or in the second seat.

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.

A horn with a piezoelectric membrane including a ceramic disk adhered to a rectangular plate. A slotted ring made of light metal is rigidly attached to the edge of the plate and comprises sixteen radial projections uniformly distributed around its circumference. Each projection has an axially facing boss forming a stiffener. The membrane assembly is attached to a molded rubber membrane that is circular to make mounting easier. The membrane comprises a flexible wavy portion enabling free movement...

A luminometer includes a chassis protected by a cover whose interior is accessible past a closure flap, a detector for measuring photons with a measuring window, a platform for supporting specimen plates, fixed or able to be displaced along a system of orthogonal axes X, Y and Z, along at least one of the axes of the plane X or Y, and an electronic module for amplification and digitizing of data and an electronic module for processing these data, with the measuring detector being movable and the...

A braking device for skates including an item of footgear composed of a quarter articulated to a shell in turn associated with a supporting frame for one or more wheels. A rod member is articulated to a plate having a slot for the sliding and pivoting of rods which clamp a pair of disks laterally associated with one of the wheels, when the quarter is tilted back by the user.

An elongated semi-product from which a clasp can be formed includes at each end at least one through-penetrating hole wherein when bent to form said clasp the semi-product forms a generally closed cavity with the mutually opposite ends of said product forming overlapping legs and the openings at the ends of said semi-product being intended to coincide in one position of the legs to enable said stem-part to be inserted easily through the two holes in said legs, wherein in another position of said...

A cover for cultivating bananas or other plants includes a plastic film having three layers. A central one of the layers is made of an ethylene and vinyl acetate copolymer, and at least one of the layers includes a UV absorber.

A container, particularly for drinks, comprising an end (5) in which a closed line of weakening (6) is formed defining the outline of a lid (7) and of a corresponding hole (8), and a lever (10) associated with the lid (7) and operable manually in order to tear the wall (5) along the line of weakening (6) and remove the lid (7) from the container wall is characterized in that it comprises a flexible tongue (9) which normally bears on the outer face of the end wall (5) and has one end (9a) fixed t...

Braking device, particularly for skates that comprise a shoe composed of a quarter articulated to a shell associated with a frame whereto two or more wheels are pivoted. A rod member is connected to the quarter and is slidingly associated at a seat that acts as a guide and is formed on a support associated with the frame.

A fixing bracket for fixing to a support a box-like structure which contains electrical components, such as a transformer, and has an external electrical wiring region, the bracket comprising a base with fastening elements for fastening the base to the support, an elastic coupling element for quick coupling of the box-like structure to the base, a box-like extension protruding from the base and which is partially open for receiving the wiring region, a sealing gasket arranged at the partially op...
