Abstract: This new type of transformer comprises a ferromagnetic drum-type core characterized in that the drum core has a plurality of holes or windows parallel to the drum longitudinal shaft to place the windings being the windows arranged close to the periphery of the drum symmetrically distributed at 360° of the circumference, each winding being parallel to the longitudinal shaft of the drum and each one of the windings crossing said longitudinal shaft. The core comprises two main components: a central body and an air gap filling system. The central body is formed by a plurality of silicon steel sheets, stacked one over the other, each of them has slots or spaces on its periphery thereof to place the windings and with an air gap filling system. Said filling system can be: wedge-shaped sheets, set of sheets extending parallel to the shaft of the core or a metal sheet wound around the central body.

Abstract: Equipment for the comprehensive care of critical neonates that ventilates, incubates, monitors and facilitates medical procedures. This equipment includes a thermal ring keeping the neonatal bubble tempered, and that slides longitudinally through its axis to leave exposed the neonate during its care. The inside of the thermal ring includes circular heaters surrounding said ring. Inside the cabin there is a closed recipient with water that takes advantage of the heat of said bubble to humidify air passing through the inlet door and outlet pipeline, which carry humidified and hot air to neonate. Furthermore, the equipment includes a water container, open at its upper part and placed out of the bubble, that allows simultaneously limiting the gas pressure of inspiration and expiration and the gas pressure of the neonate through two pipes.

Abstract: A method to linearly measure the flow of a gas in ducts, and a gas flow sensor using such a method are disclosed. In order to obtain a linear ratio between the differential pressure and the volumetric flow of a gas, a rectangular section elbow and a rectangular flexible plate located inside the elbow are used. When the flow goes through the duct linearization is obtained by combining the resistance of the duct and a variable-area obstruction caused by the plate. With linearization, it is possible to expand the measurement range of the gas flow in one duct. The sensor developed is used especially for the measurement of respiratory flow in medical applications.
