Title: Method for Producing Biodegradable Products
Creator: Shutov, Fyodor, Ivanov, George, Arastoopour, Hamid
Date: 2009-05-11, 1997-11-18
Description: A method of making a molded biodegradable food receptacle product including the steps of grinding up non-toxic agricultural waste plant...
Show moreA method of making a molded biodegradable food receptacle product including the steps of grinding up non-toxic agricultural waste plant material like soy, rice, oat and wheat hulls into particles having a range of sizes so that, if compressed in a mold, the smaller particles substantially fill the spaces between the much larger ones. Where necessary, there is added to the particles a natural and biodegradable binder-forming material, like an edible vegetable oil which will bind like a food receptacle the particles together to form a leak-proof receptacle, when inserted into a mold and compressed by the mold walls at elevated temperatures will produce compact well bound together particles. Without any chemical or physical pretreatment of the ground particles and particle-binder feed mix, the unpretreated mix, with or without small amounts of coloring, aromatic or foaming agents, is fed into a pressure-applying mold. The initial pressure and temperature preferably squeezes inherent binding-forming oils from the preferably seed hulls which freely flow through the mix. The high pressure is then partially reduced and the mold temperature is elevated to maximize the binding action of the binder materials as they solidify.

Show moreAn apparatus for generating odor upon electronic signal demand using a disk having an aroma-impregnated adsorbent and a substrate. The disk is inserted into a disk drive that receives signals from a user and/or a server computer. A controller within the disk drive supplies an electric, mechanical or thermal signal to the disk, resulting in the heating of the adsorbent. The controller may also activate a blower to distribute the scent produced by the heated adsorbent and to cool the adsorbent at the end of the scent distribution cycle.
