An aircraft window assembly (10) includes a first panel (12) having a first surface (14) and a second surface (16). In a first state in which there is no pressure difference between the first surface (14) and the second surface (16), the first panel (12) has a cross-sectional shape selected from planar, outwardly convex, or inwardly convex. In a second state in which there is a pressure difference between first surface (14) and the second surface (16), the first panel (12) has an outwardly convex cross-sectional shape.

A heating device to heat a molding face, particularly a large molding face. The heating device includes a metal sheet having a ferromagnetic layer, and a part formed into a shape that defines the molding face and a forming plane. A base of the heating device supports the metal sheet. An inductor of the heating device provides the induction heating of the metal sheet.

According to some aspects, a method is provided of casting an object from a mold, the method comprising obtaining a mold comprising a hollow shell of rigid material, the material comprising a thermoset polymer having a plurality of pores formed therein, providing a metal and/or ceramic slurry into an interior of the mold, exposing at least part of the mold to a low pressure environment so that a net flow of gas is produced from the interior of the mold into the low pressure environment. According to some aspects, a method of forming a porous mold is provided. According to some aspects, a photocurable liquid composition is provided, comprising a liquid photopolymer resin, particles of a solid material, in an amount between 30% and 60% by volume of the composition, and a water-soluble liquid.

An insulated high-temperature transport conduit for use in undersea environments. The conduit comprises a continuous steel pipe having at least a first layer of thermal insulation provided over its outer surface. The first layer of thermal insulation comprises a polymer composition having a thermal conductivity of less than about 0.40 W/mK and long-term heat resistance at continuous operating temperatures within the range from about 150? C. to above about 205? C. The first thermal insulation layer comprises a polymer composition comprising a polymer selected from the group consisting of one or more fluoropolymers, hydrogenated nitrile butadiene rubber (HNBR), and a blend of one or more fluoropolymers with HNBR. The conduit may further comprise second and third layers of insulation on top of the first layer, along with a corrosion protection coating underlying the first thermal insulation layer.

A fixing device for securing a thin-walled component according to an embodiment includes: a support; a pressing portion provided on the support and including: a pressure generator located at a center of the support; and a plurality of pressure transmitters arranged around the pressure generator and extending in a radial direction of the thin-walled component; and a plurality of elastic members connected to the plurality of pressure transmitters, wherein the plurality of pressure transmitters are configured to move the plurality of elastic members in the radial direction.

Present invention refers to a cylindrical mold with interchangeable volume wherein the inner volume of the mold can be modified by substituting the circumferential wall of said mold, re-usable and with the possibility of being able to add inserts into the mentioned walls which represent a cavity intended for either electric and/or gas type water heaters, through which the effectiveness of the development of polyurethane systems for this final application is increased.

A press tool for a press assembly includes an additive manufactured body including a plurality of stacked layers of additive manufacturable material extending between an interior side and an exterior side. The interior side has a part forming surface including a surface profile for forming a part. The exterior side has a plurality of hollow cores defined by longitudinal walls and lateral walls meeting at joints. Press inserts are coupled to the longitudinal walls and the lateral walls at the exterior side. The press inserts are configured to be pressed inward by a pressing load during a pressing operation for forming the part. The press inserts distribute the pressing load along the longitudinal and lateral walls.

The following invention is used to recycle broken pieces of crayons, A crayon package comprises a portion of the box which can be placed in an oven, said portion of the box being detachable from the package, said portion of the box is designed as a crayon recycling cartridge, the crayon recycling cartridge comprises slots, the edges of the slots are provided with guide slopes, the bottom of the guide slope is connected to the edge of the slot and the slot is expanded outward, which increases the volume of the slot. The used crayons will be placed into the slots, melted and re-casted into new crayons. And if too much used crayons are placed above the edge of the slots, when the crayon melts, the guide slope will catch the melted crayons, sending it back down into the slots, fitting to the volume of the slots.

A setup device for manufacturing a fuselage barrel, made of a fiber composite material, for an aircraft is provided. The setup device for the purpose of reinforcement includes several stringers arranged so as to be spaced apart from each other. The stringers include a base structure to form a load-bearing rigid substructure that is connected to an outwardly curved supporting surface that can be adjusted by means of actuators for the positive setup of the fuselage barrel to be manufactured with the help of form channels for accommodating the stringers. The actuators, designed as pressure-means cylinders, move one or several form channels in radial direction. The form channels are interconnected longitudinally by means of a flexible intermediate element for forming a ring-shaped supporting surface that is closed in a vacuum-tight manner and that overall is able to adjust itself in radial direction.
