| 6937792 | Method and apparatus for wavelength switching of a laser source A method and apparatus for wavelength switching a laser source. An external cavity (2) having a Bragg grating (5) is provided in an optical fiber (4). Space division switching is performed in the external cavity between a plurality of optical fi... | 08/30/2005 |
| 6079647 | Plant material processing system A system for processing plant material is provided which separates plant fibers from the woody portions of the material to produce a commercially desirable length of fiber and to grind the shorter woody portions that have been separated from the longer fi... | 06/27/2000 |
| 5970582 | Method for separating kenaf into core and fiber A method and apparatus for separating kenaf into fiber and core uses a modified stick machine conventionally used in the cotton industry for removing trash from unginned cotton. Lengths of kenaf are delivered onto the periphery of a saw cylinder so the to... | 10/26/1999 |
| 5906030 | Apparatus for decorticating plant material A method for separating woody material from plant fibers is disclosed which includes the provision of a plurality of woody material bending regions with the plant material being fed to a first and then a second one of the bending regions as bending and pu... | 05/25/1999 |
| 5870890 | Method and apparatus for detecting the mass of fiber material in a spinning machine The invention relates to a method and device for detecting the mass of fiber material (5) which is processed in a rotor spinning machine to form yarn. In order to obtain a measurement signal which is a function of the mass of fiber material and which can ... | 02/16/1999 |
| 5720083 | Method for decorticating plant material A method for separating woody material from plant fibers is disclosed which includes the provision of a plurality of woody material bending regions with the plant material being fed to a first and then a second one of the bending regions as bending and pu... | 02/24/1998 |
| 5465464 | Decorticating machine with variable speed feed and beater rollers A decortication machine for loosening and separating the core of kenaf or similar stalks from the outer fiber. The machine includes first and second sets of bladed feed rollers which have blades which intermesh to crush and split the bast fiber bark longi... | 11/14/1995 |
| 5343596 | Inclined rotatable drums and method for grading fibrous material A separator for the separation of fibrous bark from core material of chopped or crushed stalks of a crop such as Kenaf having two or more hollow bodies for rotation on inclined axes, each having a perforated wall and upper inlet and lower outlet ends. Wit... | 09/06/1994 |
| 5233727 | Device for measuring the thickness and/or unevenness of webs or wadding on spinning preparation machines. In a textile fiber preparation machine, thickness and/or unevenness characteristics of a lap (W) formed by a web or wadding of textile fibers being fed in the machine are determined for individual longitudinal strips spaced across the width of the lap. A ... | 08/10/1993 |
| 4231136 | Bagasse depithing The pith removal from bagasse fiber is significantly enhanced by the flow of fiber directly from one depithing zone to a second depithing zone without any intermediate settling or pilings of the fiber. The fiber is maintained in a separated condition duri... | 11/04/1980 |
| 4095063 | Detection device for paper or film in web form The device for detecting local thickening in webs of paper or film is based on the fact that the thickenings are first mechanically sensed and the mechanical sensing is converted by simple means into an electrical signal. The arrangement consists basicall... | 06/13/1978 |
