Abstract: A manual device including a first portion and a second portion. The second portion being at least partially fitted into the first portion and being moveable in translation relative to the first portion. The first portion having a first distal end while the second portion has a second distal end opposite the first distal end. The second portion also includes a locking device designed to prevent the first portion from moving in translation relative to the second portion only when, considered in the direction of gravity. The first distal end is arranged above the second distal end, and the locking device includes a chamber and a ball or equivalent accommodated in the chamber. The chamber is provided only in the second portion.

Abstract: Writing instrument having a body, a clip, and a retractable eraser device movable between a first position and a second position, the clip forming a housing that is designed to receive all or part of a gripping portion of the eraser device in the first position.
Abstract: A manual device for applying a coating to a support by means of tape, in which a first angle formed between the median plane of the applicator tip and the half-line extending from the middle of the application edge of the applicator tip and passing through the point arranged at the intersection of the outer periphery of the first winding and the radius of the first winding perpendicular to the median plane, is between ?1° and 10°, whereas a second angle formed between the median plane and the half-line extending from the middle of the application edge and passing through the point arranged at the intersection of the outer periphery of the second winding and the radius of the second winding perpendicular to the median plane, is between 1° and 10°.
Abstract: A compensation membrane and a pen or the equivalent including a compensation membrane. The compensation membrane being configured for compensating a pressure difference between the outside and the inside of a free ink reservoir of a pen or the equivalent. The membrane including a first portion having a first rigidity and a second portion having a second rigidity, the first rigidity being less than the second rigidity.
Abstract: A nib for a valve-free free ink writing felt pen including a first end configured to deliver ink to a writing support and second end, opposite the first end, configured to be inserted in a nib receiving part of the valve-free free ink writing felt pen, the first end and the second end defining an axial direction of the nib, the nib including a main body made of porous hydrophilic material and including one or more insert made of porous hydrophobic material, the one or more insert being configured to allow intake of air from the outside of a free ink tank of the valve-free free ink writing felt pen into the free ink tank and avoid ink leakage outside the free ink tank. A valve-free free ink writing felt pen including a nib.
Abstract: A nib for a valve-free free ink writing felt pen including a first end configured to deliver ink to a writing support and second end, opposite the first end, configured to be inserted in a nib receiving part of the valve-free free ink writing felt pen, the first end and the second end defining an axial direction of the nib, the nib having an external surface configured to cooperate with an internal surface of the nib receiving part, the external surface being configured to allow intake of air from the outside of a free ink tank, the valve-free free ink writing felt pen into the free ink tank and avoid ink leakage outside the free ink tank when cooperating with the internal surface of the nib receiving part. A valve-free free ink writing felt pen including a nib.

The second portion being at least partially fitted into the first portion and being moveable in translation relative to the first portion. The first portion having a first distal end while the second portion has a second distal end opposite the first distal end. The second portion also includes a locking device designed to prevent the first portion from moving in translation relative to the second portion only when, considered in the direction of gravity. The first distal end is arranged above the second distal end, and the locking device includes a chamber and a ball or equivalent accommodated in the chamber. The chamber is provided only in the second portion.
Abstract: An applicator device for a product, said applicator device comprising a housing, a product carriage, for supporting the product, that is mobile within the housing between an extended state and a retracted position, and a retraction mechanism configured to move the product carriage into the retracted position after a predetermined period of time in the extended state. A glue stick comprising said applicator device and an adhesive product.
Abstract: A glue stick applicator comprising a casing receiving a glue stick, the glue stick being extendable through a mouth of the casing between a retracted position wherein the glue stick is entirely housed in the casing and an extended position wherein the glue stick extends at least in part from the mouth of the casing, and a grid fitted around the glue stick at least when the glue stick is in the extended position, the grid being made of a material having higher gluing capability than the material of the glue stick.
Abstract: A method of coextruding polymeric materials into multiple layers of desired thickness to form a tubular workpiece. The method includes conveying a first polymeric material through a main extruder and a second polymeric material through a coextruder. The second polymeric material has dispersed therein an amount of electrically conductive particles effective to impart electrical conductivity to the tubular workpiece. The method further includes simultaneously extruding the first polymeric material and the second polymeric material through a coextrusion die to form the tubular workpiece. The tubular workpiece is extruded in the form of one or more outer layers having the first polymeric material and one or more inner layers comprising the second polymeric material. A tubular workpiece prepared by the method of coextruding polymeric materials into multiple layers of desired thickness.
Abstract: A manual device for applying a coating on a substrate by means of a tape has an applicator endpiece assembled to a casing and projecting from the casing. The applicator endpiece extends along a longitudinal direction and a lateral direction. The applicator endpiece has an attachment portion for assembling it to the casing, an applicator portion for applying the coating on the substrate, and a stem extending along the longitudinal direction between the attachment portion and the applicator portion. The stem is elastically deformable in such a manner that the applicator portion is movable between a rest position and an application position. The stem is an iso-stress stem.
Abstract: A multifunction writing instrument comprising a body extending along an axial direction and housing at least two writing elements, each writing element comprising a writing tip, a selector device configured to select one writing element from among the at least two writing elements, a retraction device configured to move a selected writing element between a writing position in which the writing tip of the selected writing element projects from the body and a retracted position in which the writing tip of the selected writing element is retracted, and a return device configured to bring a writing element from the writing position to the retracted position when the selector device is activated while a writing element is in the writing position.
Abstract: A device configured to capture a first image and to project a second image, the device comprising a support; a camera configured to capture, or a first mirror configured to capture and reflect towards a camera, a first image of a work area, the camera or the first mirror being mounted on the support; and a projector configured to project, or a second mirror configured to reflect and project, a second image on the work area, the projector or the second mirror being mounted on the support.
