A mould assembly for a skimmer box lid includes a mould including a floor and a sidewall extending from the floor, the floor and sidewall defining a mould cavity into which a settable material can be introduced. The floor defines at least one aperture. The assembly includes at least one mould insert having a tubular body that is configured for attachment to the floor to extend from the floor to a height that is at least substantially equivalent to a height of the sidewall, the tubular body defining an elongate passage to be in register with a respective aperture such that, when the settable material is introduced into the mould cavity and subsequently sets, the mould body, the, or each, mould insert, and the settable material form the skimmer box lid with the, or each, passage extending through the skimmer box lid so that a suitable tool can be used to lift the skimmer box lid.

An extruded part is formed by extrusion of at least one polymer melt, wherein the polymer melt or polymer melts has/have two melt fronts, which form two material inner edges of the extruded part when the polymer melt or polymer melts is/are in the solidified state; —the two material inner edges are integrally bonded to each other and define a linear binding seam of the extruded part. The binding seam is situated in a connection region of the extruded part; and —the extruded part has at least one fiber grid, which is situated in the connection region of the extruded part and is connected to the extruded part such that the fiber grid bridges the two material inner edges. The extruded part may be a part of a battery housing for a traction battery.

The present invention relates to a method and to a mould system (70) for manufacturing a shear web for a wind turbine blade as well as to a backing plate (66) for such method and mould system. The method involves arranging one or more fibre layers on top of a web mould part (61), arranging backing plates (66) at each end to create a mould cavity between the first and second backing plate (66, 68) and the web mould part (61). Each backing plate (66, 68) comprises an inner moulding surface (80), outer surfaces (98, 100) and a channel (82) or groove (83) extending between at least one of the outer surfaces (98, 100) and the inner moulding surface (80). Resin is supplied to the mould cavity via each channel or groove of the first and second backing plate (66, 68), and subsequently the resin is cured or hardened to form the shear web.

Described herein are microplates having wells with ultra-thin walls and methods of forming thereof. The microplates can be made by thermoforming processes that use ultrasound, electricity, etc., to heat a thin polymer sheet or film prior to molding. Vacuum can be optionally applied to help form or shape the wells.

A cavity mold comprises two or more sub-molds; and one or more gasket disposed between two adjacent sub-molds; wherein the gasket seals heating and cooling mediums when the cavity mold is assembled; wherein each of the two or more sub-molds comprises an outer casing; an inner casing on which a molded item is formed, wherein the cavity mold is assembled, a cavity is formed in the space between the outer casing and the inner casing; at least one heating/cooling mediums input pipe that is fluidly coupled with heating and cooling medium sources and the cavity, wherein heating and cooling mediums are pumped or compressed via the at least one heating/cooling mediums input pipe into the cavity, thereby the heating and cooling mediums pass through the cavity of the cavity mold; and at least one heating/cooling mediums return pipe that is fluidly coupled with the heating and cooling medium sources and the cavity, wherein the heating and cooling mediums are pumped via the at least one heating/cooling mediums return pipe out of the cavity; and wherein at least one of the two or more sub-molds further comprises a feed channel being through the outer casing and the inner casing; wherein the feed channel allows molding materials to be fed into the inside of the inner casing. A cavity mold system employs the cavity mold.

In some embodiments, a method receives a plurality of swatch configurations that each define combinations for lightness values, saturation values, and hue values and receives information associated with a characteristic of an image. A swatch configuration is selected based on the information where the swatch configuration defines a plurality of combinations for lightness values, saturation values, and hue values. The method generates a plurality of colors using the plurality of combinations for lightness values, saturation values, and hue values by varying at least one of the saturation value, the lightness value, and the hue value for the plurality of colors. The plurality of colors are applied to an interface that is displaying the image.

A bladder mandrel package, used to manufacture a composite structure, includes a mandrel and a wrap ply, surrounding the mandrel to form a wrapped mandrel. The bladder mandrel package also includes a first radius filler, coupled to the wrap ply at a first radius of the wrapped mandrel, and a second radius filler coupled to the wrap ply at a second radius of the wrapped mandrel. The mandrel, the wrap ply, the first radius filler, and the second radius filler are consolidated to from the bladder mandrel package.

A method of producing an in-situ molded concrete object includes positioning a form on a substrate. The form can include a leg portion, a face portion, and a frangible portion. The frangible portion can connect the leg portion to the face portion. The method includes coupling the leg portion to the substrate to create a container open on at least one side. The method also includes pouring concrete into the container. The frangible portion can be fractured to separate the face portion from the leg portion.

A closure for sealingly closing a container neck having a tubular body with a top wall, an annular side wall, an intermediate wall joining the side wall to the top wall and an annular tamper evidence band frangibly connected to an open end described by the side wall. The band includes retaining cams protruding from its inner surface. Each cam has a lead-in ramp for engaging, in use, the flange of a container neck as the neck is introduced into the open end of the body and a stop for engaging the flange to separate the band from the body when the closure is subsequently removed from the neck. Each lead-in ramp has a central recess therein.

A system and method for fabricating large composite fuselages or other vehicle structures, in which the composite structure is fabricated and cured as on a tool, segmented and removed from the tool without disassembling the tool, and then reassembled off the tool to reform the large structure. The tool includes mandrel segments attached to a substructure. The attachments may be moveable to accommodate differential expansion and contraction during curing, and the tool may be rotatable to facilitate access. A composite material of resin and synthetic fibers is applied over the mandrel segments to fabricate the structure on the tool. Caul plates are secured over the composite material, and the composite material is cured on the tool. The resulting structure is cut into part segments which are then removed from the tool, and the part segments are joined to reassemble the large composite structure off the tool.
