摘要： The present invention relates to the field of power electronics and electric engines, and describes a harmonic content correction system in power systems. The invention solves the space and weight problem associated with the core of a harmonic content correction inductor, also providing performance advantages of electric engines, such as higher available voltage at full load and higher rotational speed at full load. The invention is particularly useful in refrigeration compressors comprising a switching device my associated with a reactive element.

摘要： The present invention refers to a system and method for checking the operational status of alternative compressor valve and more particularly for checking operational status of electrically commanded valves, provided in alternative compressors used in refrigeration systems. In accordance with the present invention, said operational checking system of alternative compressor valve comprises a data processing core (5) capable of estimating one among two possible operations statuses of said metal valve (1) by varying at least one electric parameter provided by said sensor (4), wherein said step of estimating one among two possible operational statuses of said metal valve (1) is effected on the basis of the results from the comparison between said signal of electric parameter from sensor (4) and the predetermined range of data analogous to the electric parameter.

摘要： The present invention refers to a method for actuating semi-controlled valve that acts in synchronism with the compression cycles of an alternative compressor and to a system for actuating a multi-suction alternative compressor semi-controlled valve. Said method comprises at least a step of detecting at least one compression peak (1) in the course of at least one mechanical cycle (2) of the alternative compressor; and at least a step of switching the functional status of at least an alternative compressor semi-controlled valve (3) based on detecting at least one compression peak (1) in the course of at least one mechanical cycle (2) of the alternative compressor (5).

摘要： The present invention lies in the fields of chemistry and materials engineering. More specifically, the present invention describes a process of heat treatment of polymeric precursors including as active phases particle charge or a mixture of active phases with inert phases called “fillers”. It is also described a surface including ceramic polymer obtained by said process. The volumetric positive variation resulting from the formation of new phases, which for their formation, incorporate atoms from the gaseous phase, contributes to a minor shrinkage of the composition during the heat treatment process. The process of the present invention allows obtaining the desired phases in smaller treatment times and lower temperatures, when compared to a thermal treatment process as conventional pyrolysis (PC) due to the presence of highly reactive species, as for example atomic nitrogen produced by the dissociation of nitrogen molecules in the plasma environment.

摘要： The present invention relates to the compressors technological field used preferentially in cooling systems. Problem to be solved: Difficulty in detecting improper opening of the high pressure suction valve in multiple suction reciprocating compressor and, in more severe cases, interrupts operation of low pressure line(s). Problem resolution: Implementation of method which monitors at least one variable proportional to electrical engine torque, and based on detection of at least on positive peak of said variable proportional to torque of said electrical engine, identify and/or detects—in real time—improper opening of the valve.

摘要： The compressor comprises a movable assembly carrying a suction muffler and formed by: a piston (10) having a skirt (11) with an open rear end (11a) and a closed front end (11b) which carries a suction valve (50); and an actuator. The suction muffler comprises: a first and a second tubular insert (61, 62) defining a first and a second chamber (C1, C2) and having confronting open ends (61a, 62a) spaced from each other, and closed opposite ends (61b, 62b) respectively affixed to a top wall (12) of the piston (10) and to the actuator; a third tubular insert (63) internally lining the skirt (11); and an annular passage (15), between the third and the second tubular inserts (63, 62), open to the first and second chambers (C1, C2), and communicating the open rear end (11a) of the skirt (11) with the suction valve (50).

摘要： The present invention relates to a coupling system for fitting and attaching of a removable internal basket for a washing machine. The washing machine comprises a removable washing compartment configured to be mounted in the washing machine. The washing machine includes at least one convex protrusion or at least one concave groove across a portion of an inner side surface, and the removable washing compartment includes the other of at least one convex protrusion or at least one concave groove across a portion of an outer side surface. The balancing device includes a smooth surface portion across a portion of the inner side wall and the removable washing compartment includes a complimentary smooth surface portion across a portion of an outer side surface. When the removable washing compartment is mounted in the washing machine, the smooth surface portion on the inner side wall aligns with the smooth surface portion on the outer surface of the removable washing compartment and the at least one convex protrusion nests with the at least one concave groove such that the surface of the convex protrusion contacts the surface of the concave groove.
