Abstract: “AIR CHAMBER FOR APPLYING AEROSOL DRUGS WITH GEOMETRIC VALVE” particularly an air chamber (A) indicated for aerosol drug application that stands out for having a geometric valve (1) of variable cross-section, optimized constructive layout consisting of two parts (2), forming an aerosol deceleration sub-chamber (3) and another mix sub-chamber (4), in addition to a sealed compartment (C) for receiving the aerosol container (5) run by a driving shield (6) coupled to the main assembly.

Abstract: An air duct arrangement for a refrigerator with forced air circulation of the type that comprises a refrigerating compartment (20) provided with a diffusing duct (23) receiving a refrigerated forced airflow from an air cooling compartment (40). The arrangement comprises at least one distributing duct (60) disposed in the upper portion of a space (V) defined below at least one of the shelves (22). The distributing duct (60) presents a rear end (61) opened to the inside of the diffusing duct (23) and a front end (62) opened to the front region of said space (V) adjacent to the front door (21) of the refrigerating compartment (20) and provided with a plurality of front openings (64, 65, 66) turned to the front region of said space.

Abstract: An evaporator for a refrigeration system, comprising a tube provided with fins and mounted in the form of a coil, conducting a refrigerating fluid therewithin and comprising tube portions (20a) arranged parallel to each other and which are transversal to the direction of a forced airflow (F) that passes externally through the evaporator (10), from a first end region (11) of air ad to a second end region (12) of air outlet of the evaporator (10). The tube portions (20a) are arranged in the form of at l (S), having an inlet end (21) provided in the second end region (12) of the evaporator (10) and an outlet end (22) prov first end region (11) of the evaporator (10), so that the refrigerating fluid flows through the coil (S) in counterflow in relation forced airflow (F).

Abstract: The present invention mentions a system that allows a user of the wireless mobile system to have access to the PSTN. Using its mobile device (9) connected to a concentrator (1), through an mobile radio interface, when the user will be located in the neighborhoods of the concentrator, also he allows the mobile terminal (9) to have access the mobile network when the user leaves the area of covering of the mentioned concentrator. The system is composed of a mobile device (9) with capacity of access to the wireless mobile system, a concentrator (1) that it includes an adapting module of wireless access (2), that it is added to the module of access to a fixed network. The submodule of access to the analogical line (11) can be connected to a MUX/DEMUX pair (13). This pair Mux/DEMUX (13) is used to combine the users pertinent to the area of covering of the concentrator in an only analogical line.

Abstract: A system and a method of automatic defrost for a refrigeration appliance, including a hermetic compressor driven by an electric motor (1); a control unit (2); a thermal switch means (10) having a first and a second turn on condition and a turn off condition and another turn off condition of the electric motor (1); a timer (20), which measures the periods of time in the turn on and turn off conditions of the electric motor (1); a switch means (40), which selectively interrupts the energization of the electric motor (1), by instruction of the control unit (2); and a cycle counting means (30), which counts each first and second turn on conditions of the electric motor (1), the control unit (2) selectively activating the thermal switch means (10) to operate in determined turn on and turn off conditions of the electric motor (1).

Abstract: A device for indicating the formation of ice in refrigeration appliances, such as the refrigerators of domestic use, comprising a display, which is mounted inside the refrigeration cabinet and formed by a demarcated region, defined by a heat sensitive element, whose color is enhanced and distinguished when submitted to a determined temperature condition that is reached when said demarcated region is contacted by the layer of ice accumulated on the evaporator.

Abstract: A device for indicating the formation of ice in refrigeration appliances, such as the refrigerators of domestic use, comprising a display (50), which is mounted inside the refrigeration cabinet (10) and formed by a demarcated region (51), defined by a heat sensitive element, whose color is enhanced and distinguished when submitted to a determined temperature condition that is reached when said demarcated region (51) is contacted by the layer of ice (G) accumulated on the evaporator (30).
