Patent CA-2009437-A1 (CA)
Title: Improved compost bin
Inventor: BARCLAY JOHN L
IPC: C05F9/02
Filed: 1990-02-06
Abstract: A compost bin, according to the present invention, comprises sidewalls and a lid which when assembled and placed on the ground, defines a closed enclosure for receiving organic material which is to be converted into compost. The sidewalls are divided into a lower section and an upper section. The lower section has a number of air entry ports for providing air to the compost material adjacent the bottom of the bin, which material is undergoing decomposition at an accelerated rate relative to organic material thereabove.      The upper section of the sidewalls are closed and cooperate with the lid to act as a barrier to the entry of air into the bin and to retain heat generated by the compost reaction as well as serving to retain moisture driven from the material during the composting process. The moisture in the air is retained in the upper section of the compost bin and will condense on the surfaces of the lid and sidewalls of the compost bin when they are cooled, such as at night, to return the moisture to the material. The compost bin can further be improved by manufacturing the bin of a black material, preferably by adding carbon black to recycled polyethylene.

Title: Preparation and reproduction of filters and preparation of filter photographic materials
Inventor: TANIGUCHI YUKIO
IPC: G02B5/20
Filed: 1990-03-15
Abstract: ABSTRACT     The preparation of a filter comprises illuminating a photographic material and a mask located at a given distance therefrom with light from the opposite directions to make a hologram and then reproducing an reproduced image of said hologram in the photographic material, thus making it possible to prepare a precise color filter with no need of any close contact of the mask with the photographic material and without causing the mask image to shade off. According to the reproduction of a hologram applicable as a color filter, a master hologram having recorded red, green and blue stripes is located in opposition to a photographic material, and then illuminated with light obtained by mixing the three colors from the photographic material, thus making it possible to reproduce the reproduced image in the photographic material at one exposure operation, while dispensing with a photolithographic step, precise alignment or registration, etc. The process for making a filter photographic material involves laminating together, in opposite relation, a first laminate obtained by laminating a filter layer and an adhesive layer successively on a support and a second laminate obtained by laminating a photoconductive layer and an transparent electrode layer successively on a carrier film through a release layer, followed by removal of the carrier film, thus rendering it possible to prevent the discoloration, fading, etc. of the filter layer and making its preparation more efficient.
