Abstract: Uniformly sized granules are formed using the present extruder and granulation process. The extruder contains a spiral worm screw for guiding a granulation material to an apertured plate. The spiral worm screw is rotated within a chamber and is formed from a guiding slant which terminates at a blunt edge near the apertured plate. The blunt edge rubs the granulation material against the apertured plate which softens the material foming a semi-solid material. The semi-solid material is then gently pushed through the apertured plate using just the required pressure. The granules are formed when the semi-solid material hardens after exiting the apertured plate.

Abstract: Method of, and apparatus for, treating concrete blocks (10) in order to carry out an artificial aging process. For the mechanical treatment of the concrete blocks (10), the latter are positioned in a desired formation on a table top (14). Treatment bodies (17) are moved over the top side of the concrete blocks (10) with the table top (14) inclined. In this case, the concrete blocks (10) are arranged obliquely relative to one another, with the result that projecting edges and corners are partially removed.

Abstract: This invention relates to methods for manufacturing large PTFE parts by compression molding followed by sintering. The method comprises layering modified and unmodified PTFE in a mold, and compressing the layers to form a preform part. Once the preform parts are formed, they are assembled such that the areas of preform parts which are to be bonded together are the modified PTFE sections. The parts are then sintered and the modified PTFE sections bond together creating a strong, durable, bond.

Abstract: A method of installing a refractory lining in a coreless or channel electric induction furnace. For installation of a refractory lining in a furnace wall, the method comprises the steps of providing a dry refractory material between a liner form placed within the furnace and a furnace wall, placing at least one variable frequency/amplitude electric vibrator in operational communication with an element selected from a structural member of the furnace, the liner form, and a vibrator rig placed within the furnace, inducing flow of the dry refractory material by operating at least one variable frequency/amplitude vibrator in a first operational mode having a high amplitude, low frequency vibration, and compacting the dry refractory material by operating at least one variable frequency/amplitude vibrator in a second operational mode having low amplitude, high frequency vibration after inducing flow of the dry refractory material.

Abstract: A vibratory apparatus and method for agglomerating chopped bundles of wet fiberglass strands into uniform segments includes a container having a curved inner surface disposed about a generally horizontal axis where the container is mounted on a plurality of springs. The chopped bundles of wet fiberglass strands to be agglomerated are placed onto the curved inner surface at an input end of the container. A vibratory force is produced to cause the chopped bundles of wet fiberglass strands to be moved from the input end toward an output end of the container. The vibratory force causes the chopped bundles of wet fiberglass strands to be directed in a rising and falling path of rolling movement within the container. As a result of the rolling movement of the chopped bundles within the container which is produced by the vibratory force, the chopped bundles of wet fiberglass strands are converted into uniform segments by reason of agglomeration of the wet fiberglass strands.

Abstract: A method and system for pressing lignocellulosic and/or cellulosic materials to produce composite products such as medium density fiberboard subjects a mat of material to a alternating or vibratory force normal to the top face of the mat. The frequency of the alternating forces may be between 0.2 Hz and 2 Hz. This vibratory pressing action serves to cause heat to be transferred more quickly to the core of the mat from the surface, and reduces the pressing time required for thermosetting resins within the mat to cure. The system has a press for accepting the mat; a temperature sensor for sensing the temperature of the core of the mat; a control system for accepting a first signal from the temperature sensor and in response to that signal causing the press to apply vibratory forces to the mat normal to the surface of the mat when the core of the mat is below a predetermined temperature.
