10870217 · 2020-12-22 ·

The present invention includes an insulating panel for building structures, a printing device for making an insulating panel for building structures, and a method for the manufacturing of an insulating panel for building structures. The insulating panel resulting from the printing device comprises a multi-layered basalt sandwich wall that is made of external layers on either side of a middle layer. The external layers comprise a load-bearing coating made from basalt, and the middle layer comprises a heat insulating material made from basalt (basalt wool or foamed basalt). As a result, a specific sandwich-panel is manufactured from one local raw material (basalt), which possesses high mechanical and heat insulating properties. Such technology can be used for erecting comfortable buildings for colonists for long term use even under severe climatic conditions of solar system planets and satellites where appropriate raw materials exist.

CASTING APPARATUS FOR MANUFACTURING POLYMER FILM

A film casting apparatus includes a die which has a non-zero angled discharge direction relative to a horizontal plane. A chill roll is positioned downstream of the die. A film displacement device is positioned proximate to the chill roll and is configured to position the molten polymer on the chill roll and establish the thickness of the film. The non-zero discharge angle is of a predetermined magnitude to gravity assist delivery of the molten polymer to the chill roll. The chill roll is positioned to gravity support the polymer film along a first length of a first side of the polymer film. A first polishing roll is positioned downstream of the chill roll and engages and cools a second length of a second side of the polymer film which is opposite the first side. The first length is substantially equal to the second length.

A method and apparatus for manufacturing a duct bank comprising the steps of loading a frame with a series of templates, positioning the frame adjacent a pipe extruder, aligning a set of a plurality of holes with a die of the pipe extruder, extruding a pipe of a first length into the set of holes, repeating the steps of aligning and extruding for each set of holes, thereby forming the duct bank, banding the duct bank, and removing the duct bank from the frame.

Electrospinning aramid nanofibers

Example methods and articles of manufacture related to electrospun aramid nanofibers are provided. One example method may include forming a resultant solution by reacting a solution of aramids dissolved in a solvent with an electrophile. In this regard, the electrophile may perform a side chain substitution on the dissolved aramids. The example method may further include electrospinning the resultant solution to form an aramid nanofiber.

Device and method for processing thermoplastic plastic having a blowing device for a conveying screw

A device for processing thermoplastic plastic includes a storage container for receiving pieces of plastic particles or a conveying line for conveying the pieces of plastic particles, and a conveying screw following the storage container/the conveying line at a transfer opening. The device also includes an extruder following the conveying screw and an air outlet arranged opposite the transfer opening and directed at this opening. In a method for operating the device, an air stream is aligned with the transfer opening. The strength and/or the direction of the air stream is adjusted or controlled as a function of a load on the extruder.

FORMATION OF THREE DIMENSIONAL OBJECTS INCLUDING MAGNETIC MATERIAL

Implementations described herein are directed to forming objects including one or more layers of a polymeric material that include a magnetic material. The objects can be produced by forming one or more first layers that include a first polymeric material. The one or more first layers can be free of a magnetic material. Additionally, the object can be produced by forming one or more second layers that include a second polymeric material having a magnetic material. For example, the one or more second layers can include a polymeric material embedded with magnetic particles. The one or more first layers and the one or more second layers can be formed by extruding the first polymeric material and the second polymeric material onto a substrate according to a pattern. A magnetizing device can be used to magnetize the magnetic material included in the one or more second layers.
