A force-attenuating system that is interposed between an exterior surface and an interior surface, either or both of which may be subjected to percussive forces. The system has a ceiling that is positioned proximate the exterior surface and one or more inverted hat-shaped force-attenuating units with sidewalls extending inwardly convergingly away from the ceiling. Some of the units have a floor that is positioned proximate the interior surface. Optionally the force-attenuating units may be configured as clover-leaf structures with a central region and hemi-pear-shaped lobes extending therefrom. Within the lobes is a floor that is positioned proximate the interior surface. The force-attenuating system may be deployed in an automotive or non-automotive environment.

Provided is a conductive polymer dispersion, including: a conductive composite containing a ?-conjugated conductive polymer and a polyanion; a vinyl versatate polymer; and a dispersion medium.

Disclosed herein is a polarized lens film production apparatus, which may include a cover part which is configured in a circular plate; a heater part which is disposed at an inner center part of the cover part; a body part which is formed in a cylindrical shape having an accommodation space; a center part which is disposed at an inner center portion of the body part; a plurality of connection pipe parts which are disposed at a side surface of the center part and are connected communicating with the center part; a plurality of dish-shaped forming frames which are disposed at the top of each of the connection pipe part; and a vacuum hole which is defined at a center portion of each of the dish-shaped forming frames and communicates with the connection pipe part, by means of which mass production is available.

The disclosure relates to forming shaped thermoplastic articles having smooth peripheries. Many thermoplastic articles have sharp edges formed upon molding or cutting the article from a feedstock sheet. Such sharp edges can damage thin plastic films or flesh which they contact, and smoothing the edges is desirable. Described herein are methods of forming a smooth periphery for such sharp-edged articles by rolling over the sharp edge. The smoothing operation is performed by forming a deflectable flange including a bend region separated from the potentially sharp peripheral edge by a spacer, deflecting a portion of the deflectable flange, and softening at least one bent portion of the deflectable flange to yield a smooth periphery upon cooling.

The present invention discloses a heating structure for an energy-saving hot bender, which comprises a heating chamber, a connecting rod, a drive mechanism and a hot bending mould moving passage, wherein the connecting rod is arranged on one side of the hot bending mould moving passage, the hot bending mould moving passage and the connecting rod pass through the heating chamber, the drive mechanism is connected with one side of the connecting rod and is capable of driving the connecting rod to rotate, the connecting rod is provided with a plurality of fastener groups, each of the fasteners group comprises two fasteners fixed at opposite positions, and the fasteners are sleeved on the connecting rod.

A package comprises an entirety of a tray (10) having an open side and a ring-shaped cover rim (20) which is located at the open side of the tray (10), at an outer circumferential rim (16) of the tray (10), and which is connected to the tray (10) through a relatively weak breaking portion (30). For the purpose of manufacturing the package, a mold (41) is provided. Also, a sheet (40) is provided and placed in the mold (41), wherein a movement of the sheet (40) is forced in two different directions. The cover rim (20) is formed with an inner ring (21) in which an inward bulge (28) is realized, along at least a portion of the circumference thereof, as an aids in establishing a clamping connection between the cover rim (20) and the tray (10) once the cover rim (20) has been broken away from the tray (10).

A method of forming a three-dimensional object 38 with a shape determined by model data defining a model 10 of the object, characterized by the steps of: a) splitting the model 10 into a high elevation/low resolution base part 18 and a low elevation/high resolution cover part 20; b) forming a base body 30 with a shape as determined by the base part 18 of the model; c) employing a 3D printing technique for printing a sheet-like cover body 34 with a shape as determined by the cover part 20 of the model; and d) matching the cover body 34 to the base body 30 by vacuum forming.
