Apparatus and Method for In-Situ Fabrication of Bi-Layer Composite Pipe By Deformation Manufacture of Compression-Fit, Shape Memory Polymer Pipe (SMPP) Mechanically United With Host Pipe
20210048134 · 2021-02-18 ·

A method and apparatus for lining a host pipe with a shape memory polymer liner in which the liner is fed through a manufacturing assembly including a pipe tensioner, followed by a deformation tool, prior to entering the host pipe, the liner being pulled through the host pipe from a leading end, the component parts of the manufacturing assembly acting to temporarily reduce the liner outside diameter during the pulling operation, while allowing the liner to revert to at least the internal diameter of the host pipe upon removal of the pulling load. The liner being used is a shape memory polymer which exhibits the ability to return from a deformed shape to an original shape induced by an external stimulus.

20210083220 · 2021-03-18 ·

A window for a display device includes: a film having flexibility; and at least one coating layer disposed on the film. As tensile stress acting on the film increases, the film is elastically deformed in a first range of strains of the film and plastically deformed in a second range of strains of the film greater than the first range, the first and second ranges being defined by a relationship between the tensile stress and a strain of the film in accordance with the tensile stress. The film has a yield strain in a third range from about 1.9% to about 2.25%, and the yield strain is defined as the strain of the film when a yield stress of the relationship in the first range is applied to the film.

Rigid display shield
11059266 · 2021-07-13 · ·

A protective shield includes a rigid base layer, and a flexible outer cushioning layer formed from a flexible film material laminated to an outer surface of the base layer. The outer cushioning layer includes two or more layers of flexible film laminated together via an intermediary adhesive. The protective shield also has a mounting adhesive layer applied on the lower surface of the shield. The mounting adhesive allows the shield to be removably mounted to a display surface, such as a touch screen surface for an electronic device. When the shield is properly mounted to the display surface, the outer layer formed from flexible film material faces away from the display surface. The flexible cushioning layer on the outer surface of the shield allows the shield to protect the display surface such that the display surface can withstand higher levels of impacts without breaking or shattering.
