Abstract: One embodiment of the present invention includes: a step of setting a piece of a plant containing moisture inside a pressurizing apparatus and hermetically closing the internal space of the pressurizing apparatus; a step of applying a heat and a pressure to the piece of the plant; and a step of (i) enabling ventilation between the inside of the pressurizing apparatus and outside thereof after the piece of the plant reaches a predetermined molding temperature, (ii) retaining the pressure and the temperature for a predetermined period, (iii) cooling a molded article, and (iv) taking out the molded article from the pressurizing apparatus. This realizes a method for processing a plant which method makes it possible to mold a piece of a plant into a desired shape without reducing the piece of the plant into powder and without using an adhesive.

Abstract: A method for producing a pulp molded article (7) comprising the steps of supplying a pulp slurry into the cavity (1) of a mold (10) composed of a set of splits (3 and 4), the set of splits (3 and 4) being assembled together to form the cavity (1) with a prescribed configuration, to form a pulp deposited body (5), feeding a fluid into the cavity (1) to press the pulp deposited body (5) onto the inner wall of the cavity (1) for dewatering.

Abstract: A method and pulp press for recycling wood fiber products, and particularly newspaper-type pulp, into a new and useful molded product is disclosed. A quantity of paper to be recycled is mixed with sufficient water to form a viscous pulp or slurry by beating the pulp to a desired consistency for a given texture of the product to be made. The pulp press employed has a molding chamber with interior sidewalls comprised of a rigid screen through which water can pass and a rigid plate outboard from the screen. The rigid plate has channels formed therein facing the screen through which channels water can flow. One of the sidewalls is movable into the molding chamber to serve as a piston. Some means to drive the movable sidewall, such as an hydraulic jack, completes the press. The beaten pulp is poured into the molding chamber. The chamber is then closed, and the press operated by moving the movable sidewall into the chamber to compress the beaten pulp to a desired pressure and pulp density.

Abstract: Shaped ammunication for tubular weapons in the form of nitrocellulose-based combustible cartridge cases are continuously produced in a screw extruder from an aqueous suspension, stabilizers, flammable fibrous material, binders and optionally plasticizers being supplied to the suspension. The fibre-like constituents are matted in kneading and pressing zones, accompanied by the simultaneous squeezing out of the water, being shaped to an endless tubular structure, which is then cut to the length of the individual cartridge cases and is optionally also pressed to the desired dimensions and shape. Advantageously use is made of a double shaft screw extruder with kneading and pressing segments, as well as a water outlet, which is provided at its end with a tubular die. A following pressing and cutting to length means is arranged behind the extruder.

Abstract: Tubular filter elements are formed by first feeding a slurry into a tubular moulding space between a vertical core and a cylindrical fine mesh screen. Air pressure is applied to the slurry so that the liquid drains through the screen and through a screen at one base of the space, while a mass of microfibres builds up to be removed from the space for bonding by a synthetic resin. A reciprocable sleeve increases the effective height of the screen as the mass builds up. Layers of microfibres having different qualities can be assembled by using different core diameters in succession. Filter elements that need not necessarily be cylindrical can be formed by this or analogous pressure methods in which the majority of the microfibres are directed approximately parallel to one another, and/or in which one or each face of the filter element has moulded into it a perforated sheet of supporting material.
