Method of making polyester elastomer compression spring and resulting product

To obtain a polyester elastomer compression spring which does not exhibit significant permanent set when compressed by more than ten per cent, a precompression force is applied to a moulded block of the elastomer sufficient to compress the block to an extent greater than thirty per cent of the original dimension of the block as measured parallel to the precompression force. The force is then removed. The block is moulded from pellets of the elastomer. While the block is solidifying, pressure is supplied to the central portion. The block is then subjected to heat treatment, before the precompression force is applied. The precompression force can be used to bond the block between two apertured end plates. ...

Methods for Producing Coaxial Structures Using a Microfluidic Jet

The object of the invention is the provision of methods for controlled production of continuous multi-component filaments or discreet structures using a multi-component liquid jet issuing from an orifice. A multi-component jet consists of two or more liquids. The liquids may be miscible or immiscible, and form a co-axially propagating flow along the central axis of a flow cell. The working distance between the exit orifice and a substrate can be as large as 50 mm, so that in-flight processing of the jet is possible. The coaxial flow consists of an outer sheath liquid and an inner sample liquid or composite of liquids. The flow cell and the exit channel of the deposition head are heated so that the pressurized sheath liquid temperature is raised to near or above the boiling point of the sheath liquid at the local atmospheric pressure. The jet exits the deposition head through the orifice, and the outer liquid is evaporated as the jet falls at atmospheric pressure. The sheath liquid is processed thermally, optically, or chemically during flight to form a protective or insulating layer for the inner liquid or liquids. The inner liquids may contrastingly consist of an ultraviolet (UV) curable ink that is processed in-flight or after deposition. Since UV curable inks contain no volatile components, the coaxial jetted filament can be processed without producing cracks or bubbles in the sheath layer. Line widths are produced in the range from approximately 1 to 1000 microns.

The method further comprises loading a metal insert with one or more elongate blade assemblies and disposing the metal insert in the housing such that the one or more blade assemblies extend between the opposing side walls of the housing. The present invention relates to a method of forming a functional razor cartridge using rapid prototyping, and a functional razor cartridge formed using rapid prototyping.Various forms of rapid prototyping are known for producing models or prototype parts. Rapid prototyping, or additive fabrication, takes virtual designs from e.g. computer aided design (CAD) programs and, using this data, builds a model of the design in a layered manner. One of the main advantages of using rapid prototyping/additive manufacturing is the ability to create almost any shape or geometric feature.As such, rapid prototyping is frequently used in the concept stage of products that are otherwise manufactured using more traditional molding techniques. As rapid prototype methods and materials have become more sophisticated, rapid prototyping is being used more often to make workable products, as opposed to making simply models.Rapid prototyping has been used in the fabrication of models of razor handles and cartridges for some time. However, these models have not had the requisite properties to enable them to be used for actual shaving, either because of inaccuracies in dimensions or because of the material that has been used. For example, materials used previously in the formation of model razor cartridges were unable to withstand exposure to hot water without changing in property. As a result, thus far razor cartridges made by rapid prototyping have been useful only for assessing the look, dimensions ...
