The method involves determining a composition of a fuel mixture from a signal differently based on components of exhaust gas for pumping current (60) or a pumping current variation of a pumping cell of an exhaust gas probe (10) e.g. broadband lambda probe, of an internal combustion engine. The exhaust gas probe is installed in an exhaust gas channel of the engine. A defined mixture enriched fuel i...

A catalytic device (1) comprising a device body (2) that can be inserted axially in a duct (3) that is designed to be crossed by a stream of reagents. The device body forms at least one active surface, which can be struck by the flow of reagents and is affected by a material that is a catalyst for the reaction among the reagents. The device body (2) has, at least partially, a substantially tubular...

Heel piece for ski mountaineering bindings, comprising a base piece (10) fixed to the ski, a slide (20) joined to said base piece and displaceable relative thereto in the longitudinal direction (X-X), said slide having, formed thereon, a body (24) which contains the means (30) for resilient reaction of the heel piece and which has, pivotably mounted thereon, a bracket (130) having, rotationally co...

There is described a process for colouring elements made of polymeric material, in particular yarns produced selectively in polyethylene (PE), in ultra high molecular weight polyethylene (UHMW-PE) and derivatives thereof, such as HSHM-PE, comprising a step of immersing the elements (10) in a liquid colourant (1) comprising at least: water (2); pigments (3) chosen from anthraquinone colorants, azo ...

A device ( 10) for generating oscillating motion, comprising a pivot (2) that is adapted to be mated rotatably and eccentrically to a shaft (1) which in turn rotates, the pivot (2) ending at the output with eccentric means (3) that are adapted to allow mating with an element that is retained so as to slide in a single direction, the rotation of the pivot (2) within the rotating shaft (1) producing...

A level sensor (10) particularly for liquids comprising at least two capacitors (12, 13) arranged side by side, to be immersed in the same liquid (14) whose level is to be measured and having the same capacitance (C, C1) when they are immersed in the liquid (14) but a different geometry (S, S1, D, D1), both capacitors being connected to a control unit (15) that is designed to compare the signals t...

A return and damping device for sliding doors, drawers and the like comprising a sliding rail or profile for sliding shutters 204 and a shutter 200, between which the device is interposed to accompany the shutter or door to be received at the full opening or closing stop position of the shutter. Said damping device 1 comprises a shock absorber 4 of the piston type, connected by a first end 42 to t...

An electrical household appliance for washing and/or drying textile articles comprises: - a first compartment (32) for washing and/or drying, designed to accommodate the textile articles during the washing and/or drying treatment; -an enclosure (2) at least partly delimiting a second compartment (3) having an opening (31) for containing objects; -a panel (4) giving access to the second compartment...
