System and method for converting plastic into diesel
Described is a system for producing primarily diesel with some heavy fuel oil from plastic feedstock. The feedstock is received into a pyrolizer. There are two zones in the pyrolizer—one where the temperature is elevated during conveyance, and a second where the temperature is maintained. A distillation vessel receives fuel oils from the pyrolizer and agitates the oils at high temperature. A hydrogenation vessel then mixes the fuel liquid with H2 at a high pressure while recirculating to and from an expansion vessel to create converted fuel oil. A diesel distillation tank receives the converted fuel oil and creates diesel gas, which is then condensed to form a usable diesel product. Any remaining fuel oil is sent the heavy fuel oil tank. |

Automotive laminate with superior camera window
The use of camera based safety systems is growing at a rapid rate in modern automobiles. As the industry moves for full autonomous capability, the number of cameras required is increasing. At the same time, windshields, where many of the cameras are mounted are becoming larger and more complex in shape. This presents problems in the area of camera optics. For one, the camera is looking out through at least two layers of bent glass bonded together by a third layer of plastic. Mismatches in the refractive index can result in a double image. The curvature of the glass turns the window into a lens and, in conjunction with the often low installation angle, can reduce the optical clarity of the camera field of view. The laminate of the invention has a cutout in the area of the camera(s) on the interior glass layer where the cameras are mounted. |
