A method of treating sludge comprises the stages of promoting the continuous advancement and compaction of sludge inside a compression chamber between the anode and the cathode, and establishing a difference in potential in order to subject the sludge to be treated to an electrical field.
Abstract:
A kiln for slabs made of a ceramic material, comprises a support structure (2) defining a longitudinal conduit (3) developing along a prevalent development direction (A), a firing station (12) internal of the conduit (3) in which a slab (4) remains at a predetermined firing temperature for a predetermined period of time and a preliminary cooling station (13) internal of the conduit (3) and operatively located downstream of the firing station (12). A plurality of rollers (5) located side-by-side and parallel along the prevalent development direction (A) is connected to the support structure (2) and defines a sliding surface (B) of the slab (4), movement means (6) of the rollers enable transport of the slab (4) from the firing station (12) to the preliminary cooling station (13). The rollers (5) arranged in the preliminary cooling station (13) each exhibit an end (5a) which is connected to the drive means (6) via an elastic joint (7) and the preliminary cooling station (13) further exhibits a succession of electric heating resistance elements arranged along the prevalent development direction (A) below the rollers (5).
Abstract:
A process for manufacturing photovoltaic panels, comprising: predisposing a ceramic support or backsheet (1) which is located on a rest (2); making through-holes (10) in the backsheet, predisposed for the passage of electrical conductors; meticulous cleaning of the ceramic support or backsheet (1); realising an electrical circuit or bussing (3) by superposition thereof on an upwards - facing surface of the backsheet (1); covering the bussing (3) with a layer of insulating material (4) superposed such as not to cover predetermined points or zones (30) for a subsequent electrical connection; laying or arranging a first layer of wrapping (5) over the whole surface of the backsheet (1); the laying not including the zones exhibiting the predetermined points (30) laying strings of photovoltaic cells (6) such that tab ribbons (60) thereof overlap with the points or zones (30) previously arranged and left accessible or uncovered, for electric connection thereto; welding the tab ribbons (60) to the bussing (3) laying a second layer of continuous wrapping (7); superposing a protective layer of frontsheet (8); vacuum hot-pressing; cooling down to ambient temperature; electrically connecting the bussing (3) to junction boxes (9) via the through-holes (10).
Abstract:
A process for production of a self-adhesive sheet, comprising following stages: predisposing a front layer and a support layer; spreading silicone on an upper surface of the support layer,- polymerizing the silicone; applying the front layer to the upper surface of the support layer, interposing an adhesive substance between the layers; characterised in that the support layer is made of polypropylene.
Abstract:
The power take-off (10) applied on industrial vehicles eliminates noisiness generated by play between cogs of transmission cogwheels (14, 19) when the p.t.o is functioning non-operatively. Thanks to a special geometry of the cog directions of the cogwheels (19, 14) in the transmission gearings, play between cogs is eliminated when there is no power transmission. The play is re-established when the p.t.o. is functioning operatively, by overcoming elastic (21) means acting axially on the gearings (14) , and by thus returning the gearings (14) into a normal operative position.
