Publication number: 20150044440Abstract: A process for the preparation of thermal insulation sheets fashioned from certain unseparated mixtures of post-consumer plastic articles and the article, itself, is disclosed. The mixtures of such articles contain polyethylene terephthalate (PET) and polystyrene (PS) and optionally also articles made of high density polyethylene (HDPE). An unseparated mixture of such articles is provided. This mixture is crushed and shredded to form plastic flakes, and these plastic flakes are then homogenized. Homogenization of the flakes can be carried out either by melt-blending them or by further comminution to produce very fine particles of the mixed plastics. The resulting homogenized mixture of plastic types is then compression molded into sheets ranging in thickness from about 3 to 10 mm.Type: ApplicationFiled: October 24, 2014Publication date: February 12, 2015Inventor: Fares D.

Publication number: 20140224760Abstract: A novel integrated container cover is described to be used as a cup and a cover. There is a need to make a useful integrated container cover that can be used as a cup for consuming the contents of the container. This is specifically very useful for medication intake, or a soft drink intake. This invention is useful for travel purposes wherein one does not have to take two different objects if they have to carry water for drinking purposes. Integrated container cover comprises of a container cover that is used as a lid for the container. In between the container cover and the extended cup there is a thinner stretchable material or elongation means made up of synthetic material to form a bigger cup like structure. Once used it may be compressed or folded to fit into the extended cup and used as a cover for the container.Type: ApplicationFiled: February 8, 2013Publication date: August 14, 2014Applicant: King Abdulaziz City for Science and Technology (KACST)Inventor: FARES D ALSEWAILEM
