A system is described, in particular for cleaning, comprising: a high-pressure pumping unit (1) suitable for pumping water or other similar fluids at a high output pressure; an electric motor (3) connected to the high pressure pumping unit (1) for its operation; a device (5) for regulating the speed of the pumping unit (1), connected to the motor (3) for its control and for regulating the pumping unit (1) so that it delivers water at variable pressure, i.e. from 0 to 500 bar, and a very low flow-rate, i.e. from 2 to 4 1/min, said device (5) consisting of at least one programmable and/or manually operated inverter capable of controlling the power absorption of said motor (3) in a gradual manner; and a lance (15) equipped with at least one remote control system.

A method and a thermal bypass system (1) are described to modulate the heat exchanges between a closed environment between walls (2) and roof (3), in particular a living environment, and the external environment, in order to increase comfort and reduce energy consumption; the system comprises: the walls (2) and the roof (3); a heat transfer fluid; a first heat exchanger (4) located in the internal environment; a second heat exchanger (5) located in the external environment; a plurality of pipes (6) or holes which pass through the wall (2) or the roof (3) and connect the first and second heat exchangers (4, 5) so that a heat transfer fluid can circulate in both heat exchangers (4, 5); a movement device (11) designed to cause the circulation of the heat transfer fluid between the two heat exchangers (4, 5); an electronic device designed to activate the movement device (11), depending on the detected temperatures; and a shading device (8).

Disclosed are a tab structure and a pouch cell comprising the tab structure. The tab structure comprises a conductive portion and a storage container, wherein the storage container is fixedly mounted at the bottom of the conductive portion, and the interior of the storage container is a cavity for storing electrolyte. The tab structure is provided with the storage container for storing electrolyte, and the electrolyte in the storage container replenishes the needs of a battery cell in a timely manner, thereby increasing the electrolyte retention of the pouch cell. In this way, the problem of insufficient electrolyte in the later stage of the pouch cell can be solved effectively, thereby improving the cycle performance of the cell and further increasing the service life of the pouch cell.

Disclosed is a pouch cell comprising a top cover assembly, an aluminum-plastic film and a core pack, wherein top cover assembly comprises an upper top cover and a lower top cover, the upper top cover comprises a top wall and a first side wall perpendicular to the top wall, the lower top cover comprises a bottom wall and a second side wall perpendicular to the bottom wall, an upper part of the aluminum-plastic film is fitted to the outside of the first side wall, a lower part of the aluminum-plastic film is fitted to the outside of the second side wall, the aluminum-plastic film constitutes a side of the pouch cell, core pack is arranged in a space formed by the upper top cover, the lower top cover and aluminum-plastic film, upper top cover is provided with a terminal post.

An array of antenna elements (103, 201, 503, 601) has a first set of antenna elements (103, 503) having extending legs (104, 504) and configured to operate at a wavelength of λ. A second set of antenna elements (201, 601) having extending legs (202, 602) is interspersed among the first set of antenna elements with a desired configuration. The second set of elements is shifted and rotated with respect to the first set of elements such that legs of elements in the second set are disposed between legs of elements in the first set. The spacing (303, 703) between elements of the first set and immediately adjacent elements of the second set is small, for example, between 0.3 λ and 1λ.

A conductive fabric with a honeycomb structure is described, comprising a synthetic fibre base and a plurality of conductive threads woven into the base in a hexagonal configuration, a honeycomb structure on one side of the fabric, and a capture structure on the opposite side that is designed to capture electrostatic charges and discharge them onto the honeycomb structure, thus forming a closed circuit that allows uniform dissipation of electrostatic charges in all directions; the fabric has an electrical resistivity in the order of 10<-9> Ω in all directions and limited air permeability, and is made of polyester with stainless steel conductive threads and has a weight between 350 and 400 g/m<2>. A process for producing such fabric is also described.

A device (20) for actuating windows and doors is described, comprising a fastening element (2) configured to be anchored to a window or door panel; a square shaft (1) rotating inside the fastening element (2); a trigger system (3) comprising an upper body (31, 41) integral with the square shaft (1) and a lower body (32) with a plurality of recesses (33); an elastic element (4) which pushes the lower body (32) against the upper body (31, 41), wherein the upper body (31, 41) has at least two protrusions (35) configured to fit into the recesses (33) made on the lower body (32) allowing a trigger movement during the rotation of the square shaft (1).

An improved sink system is described, comprising at least one sink body (1) designed to be placed in support of at least one laundry appliance.
