Abstract: A swimming pool cleaning assembly that has at least one ultrasonic generator, a swimming pool cleaning machine including a support frame, a housing shell provided with a bottom wall and arranged around the support frame, a driver located in the housing shell, advancer supported by the frame and arranged to be place, in use, on a surface to be cleaned of a swimming pool and driven, at least one water suction opening provided in the bottom surface of the housing shell, which is designed to be put in fluid communication with water suction, driver being tightly sealed in the housing shell and electrically connectable to the supply, the ultrasonic generator being arranged at the bottom wall facing, in use, the surface to be cleaned.

Abstract: The present invention relates to a swimming pool cleaning assembly comprising at least one ultrasonic generating means (10; 46b). Advantageously the swimming pool cleaning assembly comprises a swimming pool cleaning machine including a support frame (4), a housing shell (2) provided with a bottom wall (8) and arranged around the support frame (4), driving means (3) located in said housing shell (2), advancing means (5) supported by said frame (4) and arranged to be placed, in use, on a surface to be cleaned (6, 6a) of a swimming pool (7) and driven by said driving means (3), at least one water suction opening (9) provided in the bottom surface (8) of said housing shell (2), which is designed to be put in fluid communication with water suction means, said driving means (3) being tight sealed in the housing shell (2) and electrically connectable to supply means, said ultrasonic generating means (10) being arranged at said bottom wall (8) facing, in use, said surface to be cleaned (6, 6a).

Abstract: A device for monetary transactions between magnetic media provided with rewritable permanent memory, comprising, within a containment and support structure, a control and identification unit (13), which is associated with two or more devices (14, 15) for reading/writing magnetic media having one or more rewritable permanent memories. with one or more transfer memories (17) for the two or more media, and with input/output 10 interfacing means (18) which are available to the action or perception of the user. The two or more reading/writing devices are adapted, in cooperation with the two or more memories, if enabled by the control and under the control of the interfacial means to define changes to the state of the memories of the two or more media which are equivalent to monetary transactions.

Abstract: The invention relates to a bearing structure for civil construction wherein light weight, longitudinally elongated bodies comprise an external layer of carbon fiber impregnated with epoxy; the bodies resin have a porous plastic core and are magnetically coupled to cooperating pairs of male and female constraining elements.

Abstract: A machine tool for working stones and agglomerates of inert materials having a support for the abrasive or, respectively, cutting material to contact the stone during working and a connecting part for connecting the tool to the machine which generates and transmits to the tool the movement that the tool performs during working; the support and the connecting part are fastened to each other, in a detachable manner, by way of removable locking elements. Between the support and the connecting part a layer is interposed, made of a material which is suitable to damp the mechanical vibrations of the machine, reducing their transmission from the connecting part to the support, and suitable to damp the vibrations that occur in the support during working, and reducing further their transmission from the support to the connecting part.

Abstract: The present invention concerns components for friction brakes, more particularly, vehicle braking components comprising a holding bracket characterized by plural carbon fiber layers.
