Abstract: An elliptical bicycle comprises a structural frame including two stringers in opposing arcs, one upper and the other lower, a front wheel and a rear wheel driven by a crankset from its support platforms, as well as a steering box formed by fork, steering tube and handlebar. The elliptical bicycle has multiple hinges. The structural frame is provided with a set of main hinges, each applied to a bipartite stringer having an articulation at an approximate angle of up to 170°. A secondary hinge is applied in a bipartite steering tube of the handlebar having an articulation at an approximate angle of up to 180°. A set of tertiary hinges is applied between a crankset and support platforms of the user's feet, each of them having an articulation at an approximate angle of up to 90° upwards.

Abstract: A bicycle with a rear drive assembly configured to allow pedal boards to be pivotable while moving in an elliptical trajectory and which allows a cyclist to ride in an erect position is disclosed. A front end of each of the pedal boards is pivotably connected to an end of a crank and each of the pedal boards is connected to or integral with a guide rod extending rearwardly from the pedal board. The guide rods are supported by a rear drive assembly comprising a transverse tube that is horizontally connected to a frame of the bicycle. A roller is mounted at each end of the transverse tube. Each roller has a groove which accommodates the cross-section of the guide rod.

Abstract: A modular electric power plant housed within a container equipped with a transformer for direct connection to an local power distribution system that can supply energy in remote areas is disclosed. The container provides noise control, and includes a set of units that are interconnected and are capable of generating medium-voltage electric power for supplying a local power distribution system. The units include generator units; a cooling unit; a distribution unit and transformer built-in to a tank for collecting spilled oil. The built-in tanks have double walls for collecting contaminated oil/water installed inside the container base, while air inlets for aiding cooling and at least one pair of fans are provided in the cooling unit compartment. The generator units are powered by gas, diesel, or biodiesel automotive engines. Each generator is connected to an exhaust pipe for gases that is installed on the container upper wall.

Abstract: Structural modules for layout of modular power plants are disclosed. The structural modules comprise a substation module and a power house module, basically formed by platforms having stringers and crossbars designed for the mounting of containment sheets. Both modules include interconnections including, for example, projecting tabs for the mechanical mounting of fixation elements enabling the connection between the modules and the mounting of columns, crossbars and lifting frame so as to form a structural skeleton suitable to contain the canopies, hinged doors and sliding doors and other mechanical structures making up the spatial areas designed for the installation of various equipment, such as a group of generators, fuel tanks and tanks for containment of liquids, motors, busbars. The substation module forms a support base whose stringers and crossbars are lined with containment sheets which, in turn, are secured by welds.

Abstract: “CONSTRUCTION DEVICE INTRODUCED INTO AN ELECTRICAL POWER PLANT MODULE”, more specifically relating to an electrical power plant module (1) of the type used for accessibility to electrical energy, primarily in remote areas such as isolated rural communities, mining camps, oil platforms, areas recently affected by storms, areas affected by earthquakes, offshore platforms, etc.

Abstract: “IMPROVEMENTS INTRODUCED IN AN ELLIPTICAL DRIVE MECHANISM AND A STEERING MECHANISM, APPLICABLE TO VELOCIPEDES IN GENERAL,” more specifically, it is about elliptical velocipedes (1) of the bicycle, tricycle, and scooter type, with said velocipedes having a tubular crossmember (2A) where the basic components are mounted, namely: fork (2b), handlebar mounting (2c), front wheel, rear wheel, center sprocket, and cranks, as well as an elliptical drive mechanism (M1) and a steering mechanism (M2). The structural frame (2) has a crossmember (2A), whose end is aligned with the imaginary center of the rear wheel, a tubular transverse shaft with tubular connections (3a) installed on its end portions, while a guide rod (3) that functions as a path for the sliding of the respective block (4) is attached to each of said connections.
