Принадлежит: Nike Inc

A manufacturing method, within a modularized manufacturing environment for stabilizing a phylon article that is produced utilizing a heat press, is provided. Initially, the method includes immersing a phylon article in a first tank, with a fluid disposed therein, and withdrawing the phylon article from exposure with the fluid. Typically, the midsole is heated from its production with the heat press when it is placed into the first tank. The immersion in the first tank acts to cool the phylon article, thereby stabilizing the heated phylon. The phylon article may be next placed in a second tank, with a fluid disposed therein, and withdrawn from exposure with the fluid. The fluid of the first tank may reside at a temperature comparable to or higher than the temperature of the fluid of the second tank. Recursively exposing the heated phylon article to the fluid of the tanks incrementally decreases the volume of the article.

For forming a clamping ring first the pipe is extruded. The extruded pipe is cut to form a pipe part. While extruding the pipe, its inner diameter is formed smaller than the outer diameter of a pipe onto which the clamping ring is positioned before making a pipe connection. The inner diameter of the pipe part is made larger by removing material from the inside of the pipe part but only over part of the length of the pipe part such that a stop edge is formed. The clamping ring is used on a pipe when making a pipe connection.

Supported hollow fiber membrane

Номер: US20120156485A1
Автор: Attila Palinkas, Marcell MARSCHALL, Robert Szabo
Принадлежит: General Electric Co

A hollow fiber membrane is made by covering a tubular supporting structure with a membrane dope and converting the membrane dope into a solid porous membrane wall. Optionally, a textile reinforcing structure in the form of a circular knit may be added around the supporting structure before it is covered in dope. The reinforcing structure thereby becomes embedded in the membrane wall. The supporting structure may be soluble in a non-solvent of the membrane wall, for example water, and may be removed from the membrane. Alternatively, the supporting structure may be porous. A porous supporting structure may be made by a non-woven textile process, a sintering process within an extrusion machine, or by extruding a polymer mixed with a second component. The second component may be a soluble solid or liquid, a super-critical gas, or a second polymer that does not react with the first polymer.

Incrementally Stretched Films with Increased Tear Resistance and Methods For Making The Same

Номер: US20130029066A1
Автор: Michael G. Borchardt
Принадлежит: Glad Products Co

Methods of incrementally stretching thermoplastic films in the machine direction include elongating the films in the machine direction without reducing the films' machine-direction tear resistance. In one or more implementations, methods of incrementally stretching thermoplastic films include reducing the gauge of the films without reducing the films' machine-direction tear resistance. The methods can involve cold stretching the films and imparting transverse-direction extending linear rib pattern into the film. The linear ribs can have alternating thick and thin gauges. Incrementally stretched thermoplastic films can have a machine-direction tear resistance that is approximately equal to or greater than the machine-direction tear resistance of the film prior to stretching.

An integrated process for making an inflatable laminated article comprises extruding a first film and a second film, followed by cooling the first film and the second film so that the films will not fuse to one another upon contact with each other. The films are then brought into contact with one another, and selected portions of one or both films are heated so that the films are heat sealed to one another in a selected area having a desired pattern. The unsealed area between the film provides inflatable chambers between the first film and the second film. An alternative process utilizes a film tubing in lay-flat configuration to produce a laminated inflatable article.

A laminated touch fastener is made in a continuous process on a mold roll. Flowable resin is pressed against the mold roll in limited areas to form projections extending from resin layers that are laminated to a flexible substrate while carried on the mold roll. In one example a continuous channel about the mold roll is positioned such that the resin at least partially fills the channel as the layers are formed, thereby forming in the channel a raised portion in which the resin layer is of a greater thickness than at a point between the projections and the raised portion. In another example, grooves in the mold roll receive ribs of a pressure applicator during forming of the layers, the ribs blocking lateral flow of the resin to form a desired edge profile.
