Abstract: A liquid-paint painting booth (10) comprises a painting chamber (11) inside which the liquid paint is sprayed and which is provided with a grille-lined floor (15) for sucking from the chamber an air flow which is then conveyed to a filter unit (20, 26) for filtering the air and separating the overspray with the aid of neutralizing powders which are introduced into the air flow up-stream of the filter unit. The air flow is sucked from the chamber through at least one conduit (17), the inlet of which is close to and underneath the grille-lined floor, whereby outlet mouths (23) for a laminar flow of powder transverse to the inlet and substantially parallel to the grille-lined floor of the chamber are provided in the vicinity of the sides of the conduit inlet, so that the laminar flow is passed through by the said air flow leaving the chamber via the conduit.

Abstract: An improved handling device for driving, immersing/removing and rotating motor vehicle, truck cabin, van and metal article vessel bodyworks into/from processing basins is characterized in that said device comprises a sliding frame designed for sliding on sliding rails, driven by one or two driving chains, and supporting a pair of arms bearing, at their free end portion, a swinging platform, in turn adapted to bear a skid for supporting a bodywork, the sliding frame comprising one or two winch assemblies driving respective pulleys thereon are entrained ropes, belts, chains or the like, and being associated with a respective arm at a swinging shaft, said sliding frame comprising moreover two rack assemblies, therealong slide respective end portions of the arms coupled to the frame, said swinging platform being driven by a chain driving system.

Abstract: An elevator mechanical timing connection free automatic system for immersion processing vehicle bodyworks comprises a plurality of modular processing basins (6) with four lowering devices (13-15) for each basin, operated by independent motors coupled, by pairs, to an electric control system for holding in a timed relationship the raising and lowering movement of pairs of pendulum elements (15), of an independent movement type, thereon a skid-bodywork assembly (1, 5) is loaded.

Abstract: A device for driving, dipping and turning bodyworks of motor vehicles, vans, truck cabs and metal article vessels, into processing basin, and for withdrawing the above elements from the processing basins, comprises a slidable framework, which can slide on sliding rails, supporting a pair of arms bearing, at free end portions thereof, a swinging shaft adapted to bear a supporting skid for supporting a bodywork, the sliding framework comprising at least a winch driving a drum, for winding a rope coupled to a respective arm at the swinging shaft, the slidable framework further comprises at least a rack, therealong an end portion of the respective arms coupled to framework slides.

Abstract: A device for conveying powders through pipelines including at least one pumping device which in turn includes a suction inlet and a delivery outlet and a tubular chamber with opposite ends connected respectively to the suction inlet through an input valve and to the delivery outlet through an output valve. A vacuum source and a pressure source are connected upon command to the chamber in axially distanced positions to create a vacuum respectively and alternatively in the chamber in relation to the environment upstream of the device and a pressure in relation to the environment downstream of the device.
