A pressure vessel includes a liner including a cylindrical body and a dorm portion continuous with at least one end of the body in an axial direction and includes a reinforced fiber sheet covering an outer side of the liner and made of fabric. The reinforced fiber sheet includes first yarns arranged on the body and the dorm portion such that yarn main axes of the first yarns extend in the circumferential direction of the liner and second yarns arranged on the body and the dorm portion such that yarn main axes of the second yarns extend in the axial direction of the liner. A total number of the first yarns or the second yarns that exist per unit length in the axial direction of the liner is smaller in the dorm portion than in the body.

A system and method for capturing volatile organic components from a liner curing process for pipes. The system receives steam exhausted from the liner. The steam is used for curing a curable material in the liner, but volatilizes organic components in the resin carried along with the steam. The system removes some water and passes the remaining vaporized constituents through a filter selected to capture the particular volatile organic component from the steam.

A method for monitoring a curing process of a cured-in-place pipe is disclosed. The method includes affixing a plurality of sensors to a resin layer of a liner, and determining a curing profile corresponding to at least the resin layer, the curing profile including a threshold curing value. The method further includes sensing, using the plurality of sensors, real-time data indicative of at least one curing parameter. Additionally, the method includes comparing the real-time data from each sensor to the threshold curing value, and outputting an alert upon the real-time data meeting or exceeding the threshold curing value.

According to the utility model, there is provided a film laminator for cell phones, useful for film lamination on a surface of a cell phone, including: a cell phone fixing plate, on which a through hole for receiving the cell phone is established, and a top surface of which is a horizontal face; with at least one position limiting plate for abutting the cell phone within the through hole being also fixed on the top surface. The film laminator for cell phones further includes: a film laminating plate for fixing a cell phone film; one end of which is hinged to the cell phone fixing plate, and the other end of which is movable freely so that the film laminating plate is bonded with the top surface of the cell phone fixing plate. With respect to the film laminator for cell phones according to the utility model, because the position limiting plate is provided on the cell phone fixing plate, the surface of the cell phone to which a film is to be attached can handily be kept in flush with the top surface of the cell phone fixing plate. Upon film lamination, the film laminating plate can contact with the top surface of the cell phone fixing plate and the surface of the cell phone to which a film is to be attached at the same time, so that the stress that is laid on it in the course of film lamination is very even, and a good effect of film lamination is obtained.

An overlay applicator tray including a cradle including a device slot. The device slot is configured to securely hold an electronic device in the cradle. The overlay applicator tray also can include an overlay applicator. The overlay applicator can include an overlay layer and an adhesive release liner. The overlay layer can include a top side and a bottom side. The bottom side is configured to be adhered to a screen of the electronic device. The adhesive release liner is removably attached to the bottom side of the overlay layer. The overlay applicator tray additionally can include an alignment piece coupling the cradle to the overlay applicator. The alignment piece aligns the overlay layer of the overlay applicator with the screen as the overlay layer is applied to the screen when the electronic device is securely held in the device slot. The overlay applicator tray further can include a first pull tab on the adhesive release liner. The first pull tab is configured to be pulled to remove the adhesive release liner from the bottom side of the overlay layer and expose an adhesive of the overlay layer. Other embodiments are described.

An attaching apparatus includes a cover plate fixing part and two slideable press heads. The cover plate fixing part is configured to fix a curved cover plate. The two slideable press heads are arranged at a side, configured to fix the curved cover plate, of the cover plate fixing part. Each slideable press head includes an elastic cushion configured to support a flexible display panel. The two slideable press heads are configured to be capable of moving proximate to or far away from each other, and driving the flexible display panel to be pressed and attached to an attaching surface of the curved cover plate in a process that the two slideable press heads move far away from each other.

Disclosed are a film pasting method and apparatus. The method includes: providing a protective film sheet, an electronic device and a push mechanism; aligning the protective film sheet with a screen; moving the push mechanism from a first side to a second side so as to sequentially paste the protective film sheet on the screen correspondingly. During a process of film pasting, an area where the protective film sheet is pasted with the screen defines a contact boundary proximate to the second side, the protective film sheet enters an exhaust state when the contact boundary moves, a contact angle is formed between a connection face which is formed by the contact boundary and the second side, and the screen, the contact angle gradually decreases along a moving direction of the contact boundary.

A method for manufacturing an insulation member for an appliance includes the steps of forming a porous bag with a woven fabric, filling the porous bag with insulation materials, heat sealing the porous bag, vibrating the porous bag to define a pillow, compressing the pillow within a mold to define a compressed insulation member, and evacuating the compressed insulation member within an insulated structure to define a vacuum insulated structure.

A spiral pipe-forming apparatus includes a non-circular guide portion which is rotatable with respect to an apparatus frame around a rotary axis. The non-circular guide portion is configured to be applied to a peripheral surface of a preceding spiral pipe portion. An acting portion is configured to act such that the non-circular guide portion follows a peripheral surface of an existing pipe.

Devices, methods and systems disclosed herein relate to the application of a protective film on a surface of an electronic device that instantly reduces air bubbles and eliminates the waiting time usually required when using a wet fluid solution. In one embodiment, a roller device may include a carriage or housing and one or more rollers coupled or integrated with the housing, configured to apply a protective material to a surface of the electronic device in a first orientation, and configured to function as a device stand in a second orientation. In addition or alternatively, a roller guide apparatus and/or a wedge may be utilized to assist the roller device in applying the protective material to the surface of the electronic device.
