Abstract: Processes and apparatus produce economically feasible biodiesel without subsidies. Toward that end, integrated small plants process materials containing lipids with anhydrous bioethanol as solvent and reactant, and sulfuric acid and potassium hydroxide mainly as catalysts to produce up to 3 million gallons of biodiesel per plant per year. The product is predominantly fatty acids ethyl esters (FAEE) and a chemically-enhanced organic fertilizer as byproduct. The raw material may include a wide variety of non-edible solid matter that contains lipids, which normally have from 0.5% to 80% by weight of free fatty acids in total oils. Multiple apparatus makes this process feasible. In addition to not competing with food production, since they supply fertilizer for small scale farmers, the processes and apparatus allow sustainable liquid fuel production.

Abstract: The invention relates to a method for thermally treating polyester pellets to obtain partial crystallization, whereby the polyester melt is supplied to an underwater granulating system and granulated; the thus obtained granulate are fed from the underwater granulating system into a water-solids separator. The dried granulate is then fed into a treatment device at a granulate temperature higher than 100 degrees C., without external energy or heat being supplied. The intrinsic heat of the granulate is used as the heat treatment leading to partial crystallization. The crystallization device is embodied as an at least lightly inclined reactor, into which granulate is fed at a temperature higher than 100 degrees C. The granulate passes through the reactor from the loading point to the discharge point under its own weight and exits the reactor with a temperature higher than 130 degrees C.

Abstract: Apparatus and method for reclaiming expanded synthetic resin wastes in a form suitable for subsequent injection molding. The apparatus includes a tank containing a solvent having a pump for pumping dissolved resin wastes to an evaporator. The evaporator comprises an endless belt on which dissolved resin waste is deposited and precipitates in the form of a thin film. A heater is disposed below the belt to expedite separation of solute and solvent by evaporation. A blower disposed within a housing enclosing the endless belt establishes air circulation over the belt, further promoting evaporation. The thin film is wound on a roller and subjected to a heated roller to fuse the many thin film strata into a solid, generally cylindrical mass. The solid mass is then comminuted by a granulator. Evaporated solvent is recovered in a condenser and is reused.

Abstract: The present invention describes a method and apparatus in which solid gelatin chunks are liquefied, tempered, and debubbled in a single operation. The debubbling step is accomplished by evacuating and sealing off the loaded solid reservoir and heat exchanger before initiating the liquefying step. After the vacuum is applied, the gelled chunks are pressed into the heat exchanger, where heat is applied to the gelled chunks of photographic material. This liquefies the gelled chunks of photographic material. When the liquefied product gives a positive pressure at the heat exchanger outlet, the liquefied product is allowed to flow from the heat exchanger. Liquefying and tempering are performed as the solid chunks are pushed through the heat exchanger by the reservoir piston.

Abstract: The present invention features a process and apparatus for fabricating ceramic substrates. The apparatus comprises an extruder of the ram or screw type for forcing the ceramic materials through a die to form a log. After leaving the extrusion die, the log enters a conveyor apparatus.

The conveyor apparatus features a support surface for carrying the ceramic materials. The support surface has a plurality of apertures through which the gaseous fluid (air) is directed for supporting the moving log. About the support surface is disposed a mantle for confining the gaseous fluid (air) about the rapidly drying ceramic log. The gaseous fluid (air) is maintained at a relative humidity of approximately between 85 to 97%, and preferably within an approximate range of between 90 and 95%.

Abstract: An apparatus is provided for the uniform and rapid heating of foodstuffs, usually for pasteurization and sterilization purposes, by means of microwave energy. The cross-sectional shape of the outlet of the wave guides through which the microwave energy is supplied is selected so as to be geometrically similar to that of the product to be treated. A spacing is maintained between the outlet aperture and the surface of the product, which spacing is not greater than the wavelength of the microwave energy be used. These features provide rapid and appropriate processing of a food product while, at the same time, preventing the harmful overheating of the edge regions of the product.
