Title: A dry-pack method of recycling organic fibre and other polymeric materials into building blocks
Inventor: PLATTS ROBERT
IPC: E04B1/00
Filed: 1998-04-22
Abstract: Methods and apparatuses are disclosed by which "waste" organic fibre and other polymeric materials, chopped or shredded into strands, are oriented, packed together and tightly enclosed in strong mesh to form building blocks. The orientation of the strands and the friction between them creates a firm block structure which is particularly suited to serve as the stabilizing, shear-resisting, insulating core of stressed skin sandwich walls and other building components; methods of forming such components are disclosed. The process entails no chemical treatments or binders, and little energy, so offering a means of benign waste management and sustainable production of housing. The preferred or primary polymeric wastes are wood, cereal straw, bagasse, and other plentiful cellulose fibre materials mechanically prepared from construction wastes, tree canopy, mill wastes and agricultural wastes. A significant proportion of the block can, however, be comprised of shredded waste plastics without unduly degrading the block properties dependent upon friction between the strands.

Filed: 1998-12-18
Abstract: To facilitate saving of image data and movement of an image. An original image is displayed on a screen of a display device. An area to be extracted (cut out) from the displayed original image is designated by a mouse. Image data of an area other than the designated area is changed to image data representing a specified color. Pixel image data and coordinate data representing pixels in the (designated) area excluding the area of the specified color are produced.  Pairs of the pixel image data and the coordinate data is stored. Alternatively, a set of pixel image data and a set of coordinate data are respectively compressed, and compressed pixel image data and the compressed coordinate data are stored. To perform proper color correction (conversion) even when a user image is inlaid in a template image to produce a composite image. A position, in which the user image is to be inlaid, on the template image is defined by mask information. The template image and the mask information are correlated with each other. The user image is inlaid in the position, on the template image, defined by the mask information, to produce a composite image. Data representing the produced composite image and the corresponding mask information are transmitted from a client computer to an image synthesizer. In the image synthesizer, the mask information is referred to, to separate the template image and the user image from the composite image. The template image and the user image, which have been separated from each other, are individually subjected to color correction in the image synthesizer. The template image and the user image, which have been respectively subjected to the color correction, are resynthesized.
