Appl.No 17566078 Applicant COMMISSARIAT À L'ENERGIE ATOMIQUE ET AUX ENERGIES ALTERNATIVES Inventor Hicham MASKROT

A manufacturing method enabling the obtainment of a functional part essentially formed in a metallic material, all or part of the functional part delimiting a filtering medium permeable to a fluid and delimiting first and second main faces for a preferred circulation of the gas through the filtering medium. The method includes a main phase consisting of an additive manufacturing method in successive passes from a support tray. Each pass includes the deposition of at least one layer of the metallic material, the deposited material adhering to the metallic material deposited before. The deposition is controlled at each pass so the stack of metallic material constitutes the functional part. The filtering medium includes a coalescent network of connecting strands interconnected according to a three-dimensional spatial distribution between the faces, the connecting strands of the network delimiting therebetween pores spatially distributed within the filtering medium in three dimensions between the faces.

A macro electrically active mask includes two conductive layers separated by at least one filtering and insulating layer. The conductive layers are connected to each other by a power source. The power source includes an oscillator and a high voltage transformer. The power source generates a periodic voltage with a fundamental frequency and multiple harmonic frequencies. The power source is connected between the two conductive layers and the periodic voltage generates a periodic electric field between the two conductive layers. The fundamental frequency, the duty cycle, and the amplitude of the periodic voltage are configured to inactivate the microorganism that pass through the electric field.

A respirator mask 10 comprising a chassis, seal, formed filter sheet comprising multiple sheets, elastic headbands 25 and clasps 28. The chassis provides a substantially circular framework 22 with a pair of ribs 26 that may be in an X shape. The filter is attached to the exterior of the chassis and supported by the ribs to form a dome- or cup-shaped pocket. The seal is attached to the framework to provide a face seal such that the cup portion can provide an air pocket. Two clasps 27 may be arranged on either side of the framework aligned at approximately 40° to each other. The headband may be adjusted by a hinge mechanism. A method of making a cup-shaped filter for a mask comprising placing multiple filter sheets into a cavity cast with a crease forming plunger frame and applying a cup-shaped plunger to provide an evenly creased filter sheet.

Disclosed is a mask having a face contact function, wherein a structure of a mask body can be directly changed by a wearer so that the mask body does not lift off the face regardless of the structure or size of the wearer's face. To this end, the mask body comprises a close-contact member including: a first cut line which is provided in the upper portion of the left end thereof and forms a first fastening protrusion according to an external force; a cut line for the first fastening protrusion, which is provided in the lower portion of the left end thereof and provides a space in which the first fastening protrusion is to be fitted so that the upper portion is maintained in a close contact with the lower portion; a second cut line which is provided in the upper portion of the right end thereof and forms a second fastening protrusion according to the external force; and a cut line for the second fastening protrusion, which is provided in the lower portion of the right end thereof and provides a space in which the second fastening protrusion is to be fitted so that the upper portion of the right end is maintained in close contact with the lower portion of the right end. According to the present invention, even when the mask body that is in contact with the curved contour of the cheeks lifts off due to the size or curve of the wearer's face, the mask body may easily come back into contact with the wearer's cheeks. In addition, when the wearer intensely moves and an external force is applied to the mask body, the contact-close state with the cheeks can be stably maintained.
