Abstract: An adapter device for attaching a vacuum cleaner bag to a retaining plate intended to be received in a vacuum cleaner bag retaining device of a vacuum cleaner and comprising a retaining plate through hole is described. The adapter device has a base element comprising a first surface and a second surface as well as a through hole which extends between the first and the second surface. The clamping arrangement comprises at least one deformable clamping element which is attached or can be attached to the base element and can be brought into a first and a second deformation state.

Abstract: A watering device for irrigation of non-circular areas is disclosed. The watering device comprises a deflector having an uneven curved surface designed to cause liquid meeting the deflector to reach a distance that changes respective of the uneven surface to cover an irrigation area; a spiral sector object connected to the deflector and providing an adjustable spray orifice for adjusting an irrigation pattern of the watering device; and a two-diameter tubular body connected to the spiral sector object and allowing the liquid to flow from a pipe to the uneven curved surface of the deflector.

Abstract: An irrigating device and a deflector for even spraying of liquid across non-circular areas are presented. The irrigating device includes a base comprising at least a groove; a cap; and a deflector including at least a butterfly ridge, a groove, and a plurality of hydrodynamic ribs, wherein the butterfly ridge is structured with a continuous series of angles to allow equal quantity of liquid per distance on the radius and diagonal, wherein the groove is structured to allow full liquid coverage at a zero point, and wherein the plurality of hydrodynamic ribs are structured to control at least the irrigated distance.

Abstract: An environmental cabinet including at least two opening leaves which have an insulating glazing unit composed of at least two glass sheets between which a vacuum has been created. The sheets are joined together around their periphery by an inorganic seal. The sealing between the two opening leaves is achieved by a vertical member which overlaps the edges of both opening leaves and is fixed to one of the edges.
