An energy absorbing barrier system comprises a plurality of composite concrete barriers, each barrier including a reinforced concrete section having a back wall upon a support base. The support base is connected to a concrete veneer face section having an upper portion and a lower portion. The face section forwardly slopes from the support base to form an obtuse angle therewith such that the upper...

The present invention relates to a method of splicing the expiring end of a board ply (3) or similar web being paid off from a roll (1) with the starting end of another ply to be paid off from a new roll (2). In the method, the starting end of the new ply is passed close to the path of the expiring ply oriented toward the incoming direction of the tail of the expiring ply. In this position, the en...

Method of producing a nonwoven material by hydroentangling a fiber mixture containing continuous filaments, e g meltblown and/or spunbond fibers, and natural fibers and/or synthetic staple fibers. The method is characterized by foamforming a fibrous web (14) of natural fibers and/or synthetic staple fibers and hydroentangling together the foamed fiber dispersion with the continuous filaments (11) ...

The invention concerns an improved automatic mechanical valve for buoyancy control devices (BCD) comprising a main body (4), connected to a first not compensated stage (2) of a dispenser so that low pressure air is received, about 10/11 bar, said main body (4) providing first (7), second (8) and a third (9) chamber, each one of said chambers (7, 8, 9) providing a piston (11), movable within a cyli...

An angular positioning and retention device (1) particularly for a windscreen wiper lever (2) of a switch control unit for vehicles is provided with a cam body (3) defining a plurality of seats (12) and a detent element (15) which can be coupled to the windscreen wiper lever (2) turnable about a pivot axis (10) to selectively engage the seats (12); at least one of the cam body (3) and the detent e...

A control device (1) has first and second input terminals (2, 4) which can be connected in use to an electrical energy source (5), typically the battery of the vehicle, and an output terminal (6) providing a control signal for the actuator (7). The control device (1) includes resistive potential divider means (10) connected between the first and second input terminals (2, 4) and having a plurality...

A control method comprises the steps of: selectively supplying fuel gas to some cylinders (4) of an engine (2) on the basis of the power required from it; selecting the quantity of fuel gas supplied to each of the cylinders (4); and selecting, in successive engines cycles, different cylinders (4) to supply with fuel gas according to a predetermined scheme of rotation.
