A method of manufacturing a composite material that is formed to include an aperture is provided. The method includes disposing a plurality of woven substances including reinforcement fibers on a jig having a protrusion to fit the woven substances on the protrusion and thus provide the aperture. Additionally, the method includes integrally mounting the jig and a plurality of the woven substances in a mold, and adding a resin to the mold to immerse the plurality of the woven substances with the resin.

Spraying head having a head body forming a housing having an axis X defining an insertion opening and a substantially flat internal wall through which a central spraying opening extends and a spray nozzle, substantially tubular in shape and axially engaged in the housing of the head body via the insertion opening, the spray nozzle having an inlet that opens into a central internal duct and an external wall defining a central cavity centred on the central spraying opening and a plurality of swirl channels that open tangentially into the central cavity and communicate with the central internal duct. The swirl channels extend axially beneath the central cavity as far as the central internal duct, so as to be in direction communication therewith.

A tray having: an annular sidewall having upper and lower annular peripheral edges, an upper annular peripheral rim which is integral with the upper annular peripheral edge, and a base having an annular peripheral edge which is integral with the lower annular peripheral edge of the sidewall, wherein the rim, the sidewall and the base are composed of a thermoplastic polymer and the sidewall and the base define a central concavity for packaging a product, wherein the base has a lattice structure of elongate foam ribs interconnected by foam junctions, wherein each foam rib has opposite ends, and each end is integrally connected to either the annular peripheral edge of the base or one of the foam junctions, wherein each foam rib and each foam junction has opposed upper and lower unfoamed solid skins of the thermoplastic polymer on opposite sides of a central cellular foam core of the thermoplastic polymer.

A method of making a blind hole in a wall of a multi-section tank during manufacture includes inserting a thin, flexible composite spacer ring in a hole in a composite material between mating parts of a soluble tool. The composite spacer ring is cured to the composite material during curing and maintains the hole between sections of the tank once completed.

In one example, a process for making a micro device assembly includes placing a micro device on a front part of a printed circuit board, molding a molding on the printed circuit board surrounding the micro device, and then forming a channel to the micro device in a back part of the printed circuit board.

A container having an annular sidewall with upper and lower annular peripheral edges and a lattice structure of elongate ribs interconnecting the upper and lower annular peripheral edges, wherein the lattice structure is an open framework defining a plurality of sidewall openings, and a base having an annular peripheral edge which is integral with the lower annular peripheral edge of the sidewall, the annular peripheral edge of the base surrounding a base wall structure which is integral therewith, the base wall structure having at least one injection moulding sprue at a central region of the base wall structure, wherein the at least one injection moulding sprue is connected to the upper annular peripheral edge of the annular sidewall by the base wall structure, the annular peripheral edge of the base, the lower annular peripheral edge of the sidewall and the lattice structure of the sidewall, wherein the sidewall and the base are composed of a thermoplastic polymer and define a central concavity for packaging a product, and wherein the container further has a flexible sheet which is bonded to the lattice structure to cover the sidewall openings and form a sealed sidewall surface of the container.

A compression molding tool comprises a cavity member (101), a core member (102), and a compression system (103) for moving the core member towards the cavity member from a first position to a second position where the cavity and core members define a shape of an element produced by compression molding. The cavity member comprises a first projection (105) having a first side surface (106), and the core member comprises a second projection (107) having a second side surface (108) parallel to the first side surface. The first and second side surfaces are against or near each other when the core member is in the second position. Thus, a through hole, or a thin wall that can be punctured to form a through hole, is formed between cavities formed by the first and second projections in the element produced by compression molding.

A method of manufacturing an optical spacer includes dispensing thermal glue within a mold; pressing the thermal glue using an optical spacer substrate to generate an optical spacer including an aperture; and, releasing the mold from the optical spacer. The thermal glue may be cured prior to releasing the mold from the optical spacer.

A fluid transfer assembly includes one or more fluid conduit and a body portion. The body portion defines a fluid channel within the body portion that is in fluid communication which each of the one or more fluid conduits when the body portion is in an elongated state. The body portion has an elongated stat in which the body portion is configured to elongate in a range of 150 percent to 1500 percent from the unelongated state without breaking to facilitate removal of a mandrel from the fluid conduit.

An assembly to form a seal around a conduit. The assembly includes a mold with multiple sections that mate together to form a cavity that extends around the conduit. A retaining plate is configured to mount to the conduit and positioned in contact with the mold. A knuckle has a clamshell configuration with a first jaw and a second jaw that are pivotally connected together by a connector and movable between an open position and a closed position. A spring clip is positioned between the knuckle and the retaining plate with the spring clip configured to apply a force to maintain the retaining plate in contact with the mold.
