A manufacturing method of filling a resin into a housing includes the steps of: providing a housing that has at least one recess, with the recess having first and second spaces, and the first space being disposed above the second space; inverting the housing; injecting a fluid into the recess to fill the first space, with the fluid having a viscosity coefficient and a surface tension less than those of water; and injecting a first resin into the recess, with the first resin having a specific gravity greater than that of the fluid, such that the first resin fills the first space and the fluid fills the second space.

The invention relates to novel multicolour, multitexture and multimaterial cosmetic products as well as to a method for hot casting cosmetic compositions containing fats, in particular an oil.

Said method advantageously renders a mold superfluous and allows the creation of products that include a plurality of compositions such as to produce highly original appearances. Said method also allows the production of products with a very irregular raised designs.

In one aspect, multi-layer tissue simulations are provided. In another aspect, male genitalia models are provided. In another aspect, abdominal surgical wall inserts are provided. Systems and methods associated with these devices are also provided.

A method of injecting a sealing gel into a recess of a work piece, comprising steps of: injecting the sealing gel into the recess and stopping the injection of the sealing gel when the sealing gel reaches a first depth less than the total depth of the recess; after the sealing gel has cooled and solidified, continuing the injection of the sealing gel into the recess and stopping the injection of the sealing gel when the sealing gel reaches another depth higher than the first depth; and repeatedly performing the previous step until the cooled and solidified sealing gel in the recess has a top surface beyond a sealing interface surface of the work piece.

A method, a dosing device and a system for manufacturing of a lipstick mine out of at least two pasty substances are described. The method comprises inserting of a first end portion of a dosing device into a form whereby the first end portion of the dosing device comprises at least one outlet nozzle, filling of the first end portion of the dosing device with a first pasty substance, increasing of the gas pressure in the first end portion of the dosing device whereby the first pasty substance through the pressure is pressed out of the at least one outlet nozzle, removing the first end portion of the dosing device out of the form and filling up the form with a second pasty substance.

The present application relates to a method of fast curing transparent casted substrate, usable for making optical articles such as ophthalmic lenses, which comprises the steps of:providing a fast room-temperature polymerizable composition:providing a catalyst composition;providing a casting mold assembly containing two unsealed molds each having an inside surface and an outside surface; and optionally providing a light filtering element placed or configured to be placed between the two moldsdepositing the catalyst composition:on the inside surfaces of at least one of the molds; and/oron at least one of the surfaces of the light filtering element which is thereafter positioned in the mold assembly;closing the casting mold assembly so that the inside surfaces of the molds form together the molding cavity:filling the fast room-temperature polymerizable composition in the molding cavity of the casting mold assembly already containing the catalyst composition deposited on the inside surface of at least one of the molds:curing the filled mold assembly to obtain a transparent solid substrate, said curing step comprising: a) a first step for polymerizing said composition at room temperature to obtain a gel; and b) a second step of post-curing the gel to obtain the transparent solid substrate; andrecovering the transparent solid substrate from the casting mold assembly.

A lens comprises an internal cavity structure formed by dissolution of a soluble insert material. The internal soluble material may dissolve through a body of a lens such as a contact lens in order to form the cavity within the contact lens. The cavity within the lens can be shaped in many ways, and corresponds to the shape of the dissolved material, such that many internal cavity shapes can be readily fabricated within the contact lens. The insert can be placed in a mold with a pre-polymer material, and the pre-polymer material cured with the insert placed in the mold to form the lens body. The polymerized polymer may comprise a low expansion polymer in order to inhibit expansion of the lens when hydrated. The polymer may comprise a hydrogel when hydrated. The soft contact lens material comprises a sufficient amount of cross-linking to provide structure to the lens and shape the cavity.

A method to manufacture optics and optical subsystems. In one aspect, a method to manufacture an optical-element in accordance with the present disclosure comprise the steps of: Printing at least a part of a mold with an additive manufacturing printer. Optically figuring the mold to the specifications of the desired optical-element. Printing a nanocomposite-ink into the mold. Selectively, curing the nanocomposite-ink. Repeating at least the steps of deposition of the nanocomposite-ink and selective curing, until the mold is sufficiently filled and cured. Optionally, releasing the optical-element from the mold.

The invention concerns a device and a method for producing a pipe lining in a pipe by introduction of a hardenable mass, wherein the mass is pumped through an outlet into an annular gap, which is formed by the pipe wall and the device arranged in the pipe. The device has a former, which is guided within the pipe in a predetermined spacing from the pipe wall along the pipe axis, so that the annular gap between the pipe wall and the former has a predetermined cross-section.
