Abstract: A dry erase ink for a writing instrument. The dry erase ink includes, as the main organic solvent, a solvent selected from the group consisting of n-propyl acetate, isopropyl acetate, or mixtures thereof.

Abstract: A clothing article having a support member is provided. The clothing article includes an outer shell, a portion of the outer shell being dimensioned to fit loosely on a body of a wearer. A support structure has a support member supporting the body of the wearer when positioned thereon, and fits snugly on the body of the wearer, At least one tether portion extends between the support member and at least one connection region that is secured to the outer shell. At least a part of the at least one tether portion is dimensioned to enable the outer shell to move substantially freely relative to the support member when the clothing article is worn by the wearer.

Abstract: A new spray process allows for deposition below a critical velocity limit of cold spray, while providing adhesion. Post deposition heat treatment has shown excellent coating strength. A wide variety of materials can be deposited. The spray process is based on ShockWave Induced Spraying (SWIS) but with much slower spray jet projection velocities. High porosity, pore size control, and porosity control are demonstrated to be controllable. Preheating of feedstock and uniform temperature of the SWIS delivery allow for the deposition below critical velocity.

Abstract: A display, securing and transporting device can be used with many types of footwear, including boots, dress shoes, sandals, cleats, high heeled shoes and casual shoes. The device comprises a first elastic body adapted to retainingly and releasably engage a perimeter of a first one of a pair of footwear. The first elastic body defines a toe receiving portion and a heel receiving portion; and a lateral band connects the toe receiving portion and the heel receiving portion. A second elastic body is adapted to retaining and releasably engage a perimeter of a second one of a pair of footwear. The first elastic body and the second elastic body are coaligned and attached to one another at their respective lateral bands. A mounting means is provided on the device to receive a hanger.

Abstract: An alcohol-based dry-erasable ink for a writing instrument including, as separation agent, a mixture of glycerol, glycol and pentaerythritol ester.

Abstract: A pencil lead and a pencil containing the pencil lead wherein the pencil lead is polymer-based, extrudable, non-expanded, non-calcined and comprises graphite, of which 25% to 100% by weight or 50% to 100% by weight of the graphite, in relation to the total weight of the graphite, is expanded graphite.

Abstract: The invention relates to a laser nozzle that can be used in laser cutting, notably with a fibre or disc laser, comprising a nozzle body comprising an axial housing passing axially through said nozzle body and comprising a first outlet orifice situated at the front face of the nozzle body, and a movable element comprising a skirt-forming front part arranged in the axial housing of the nozzle body, said movable element being capable of translational movement in the axial housing of the nozzle body and comprising an axial passage with a second outlet orifice opening onto the skirt-forming front part.

Abstract: A writing or coloring pencil has three layers obtained by co-extrusion, including an unexpanded polymer-based lead, an unexpanded intermediate protective layer surrounding the lead and comprising an ethylene (C1-C4 alkyl) acrylate copolymer, alone or as a blend with a styrene polymer, and an expanded styrene polymer-based synthetic wood material surrounding the intermediate protective layer.

Abstract: The invention relates to a laser nozzle that can be used in laser cutting, notably with a fibre or disc laser, comprising a nozzle body comprising an axial housing passing axially through said nozzle body and comprising a first outlet orifice situated at the front face of the nozzle body, and a movable element comprising a skirt-forming front part arranged in the axial housing of the nozzle body, said movable element being capable of translational movement in the axial housing of the nozzle body and comprising an axial passage with a second outlet orifice opening onto the skirt-forming front part.

Abstract: A wax-based coloring crayon for a porous surface and for a non-porous surface includes at least one wax, an ethoxylated fatty alcohol, stearin, a filler, at least one pigment, and optionally an additive.

Abstract: The present invention thus relates to a writing or color pencil comprising the following 3 layers obtained by coextrusion a polyolefin-based non-expanded lead, a non-expanded protective intermediate layer surrounding the lead and comprising a mixture of polystyrene and EVA, and an expanded synthetic wood material based on a styrene polymer surrounding the protective intermediate layer, the protective intermediate layer thickness/lead radius ratio being between 0.05 and 0.17, advantageously between 0.07 and 0.15.

Abstract: The present invention concerns an extrudable, unexpanded paper pencil lead, comprising, by weight relative to the total weight of the lead, between 40 and 60%, and advantageously between 44 and 50%, of graphite; between 15 and 40%, and advantageously between 20 and 35%, of a polyolefin; between 5 and 15%, and advantageously between 6 and 10%, of a colorless mineral filler; between 5 and 20%, and advantageously between 5 and 15%, of carbon black coated with or mixed with a polyolefin wax or a polyolefin; between 0 and 16%, and advantageously between 5 and 15%, of an additive. It further concerns the paper pencil comprising a lead according to the invention.
