Patent EP-0439918-A1 (EP)
Inventor: FLEMING JAMES WILLIAM JR
IPC: C03B29/02
Filed: 1990-11-23
Abstract: To attain high strength optical glass fibers, the glass preforms, from which the fibers are drawn, must generally be free of surface imperfections such as bubbles, and air lines. It has been discovered that these imperfections can be removed quickly and cleanly by contacting the preform surface with a substantial portion of the electrically conducting plasma region (the plasma fireball) extending from a plasma torch. Significantly, the surface material is substantially removed by vaporization, due to the extremely high plasma temperature (>9000°C at the plasma center) of the isothermal plasma torch. Though the temperatures in the tail of the plasma fireball are substantially less than at the plasma center, the temperatures are generally still several thousand degrees centigrade. These tail temperatures typically are sufficiently high to cause vaporization of most refractory dielectrics making the inventive method applicable to the fabrication of a wide variety of articles comprising refractory dielectric bodies. 
     Advantageously, selective etching, according to one aspect of the inventive method, is used to remove fiber preform eccentricity and to fabricate optical fiber preforms with non-circular cross-sections for such applications as fiber sensors. Selective etching can result by controlling the plasma fireball location, the rotation of the silica preform, and/or the travel of the fireball across the preform. Significantly, the fireball location is controlled, among other ways, by injecting into the torch an additional gas that has a high ionization threshold or by inserting a probe along the axis of the torch. In either case, a substantial portion of the plasma fireball is advantageously "pushed" outside the torch for ease of contact with the silica preform surface, or any other refractory dielectric being processed.

Abstract: A reference area 14 usable with a rectangular form 10 when the form is used with a computer controlled printer. The reference area 14 having a pattern 16,18 and a reference point 20. The pattern 16,18 allowing the location of a mark printed by the printer on the pattern to be readily identified on an equivalent reference area 24 displayed on a display monitor 23 for the computer. The reference point 20 is positioned so it will receive a reference mark when printed on the reference area 14 by the printer provided the form 10 is not misaligned in the printer. A reference mark received at the reference area 14 provides information relative to the reference point 20 that is a measure of the amount of vertical and horizontal misalignment of the form 10 in the printer. 
     This information, when placed in the computer, makes it possible for the computer to correct for any misalignment before any printing is done on the form 10.

Abstract: The invention relates to a packaging material in small pieces for filling cavities in solid packaging containers. The packaging material consists of an outer cover made of a coarse-pored, highly air-permeable, thin paper, such as e.g. baker's silk, which encloses a filling of paper waste (chips) from shredders or the like. The ball-like packaging containers of up to 10 cm diameter are folded or glued. The filling tends not to crumble, and all materials involved degrade easily. The packaging container is very elastic as a result of its air-permeability and adapts well to the hollow shapes to be filled.

Abstract: For placing an essentially vertical screen in the ground a trench is dug in the ground, a mixture such as a bentonite-water mixture or a bentonite-cement-water mixture which can form an impenetrable layer is fed in to said trench, a sheeting panel is connected to an insertion sheet, the insertion sheet with sheeting panel is moved downwards in the mixture in such a way that a vertical locking edge of said panel and a vertical locking edge of a panel already placed in the trench are slid into each other, the connection between the insertion sheet and the sheeting panel is broken, and the insertion sheet is pulled up, so that the next sheeting panel can be connected to said insertion sheet, which actions can be repeated until a tight wall of the desired length and shape is formed from the sheeting panels in the trench. In order to avoid problems during the placing of screens of great height (for example of about 30 metres) in the ground, each sheeting panel is fixed near the top edge of an insertion sheet to said sheet, the sheeting panel is taken into a vertically downward hanging position by pulling said sheet up out of the trench and, before the combination of sheet and sheeting panel connected to it are moved downwards in the trench, this combination is moved over approximately the width of a sheeting panel in the lengthwise direction of the trench.

Abstract: The superconductor magneto-resistive element 14 is installed in a center portion surrounded by two coils 15 and 16 which generate A.C. and D.C. bias magnetic fields respectively. The coils 15 and 16 are respectively connected to A.C. and D.C. power sources for applying A.C. and D.C. bias magnetic field to the element 14. 
     With the output signal of the element 14, the fundamental component having the frequency component same as that of the A.C. bias magnetic field and the quadratic harmonic component having the frequency component twice as that of the fundamental component are calculated using the Fourier transform. The calculated value of the fundamental component is divided by the value of the quadratic harmonic component, thereby removing the change of the output signal of the element 14 due to the fluctuation inherent in the element 14, enabling to measure an external magnetic field with high accuracy.

Each perforation through the separator plate is surrounded by a flattened manifold wet seal structure [46] [45] extending to contact the electrolytes on each face of the separator plate to form separator plate/electrolyte wet seals under cell operating conditions. Conduits through the extended manifold wet seal structure provides gas communication between one set of manifolds [24] and the anode chambers on one face of the separator plates, conduits through the extended manifold wet seal structure on the opposite face of the separator plates provides gas communication between a second set of the manifolds [25] and the cathode chambers on the other face of the separator plates, and conduits through the extended manifold structure of a reactant gas manifold [50] [51] provides communication to interspersed reforming chambers. Extended wet seal structures formed of thin plate metal provide limited flexibility and resiliency to assure good sealing. This structure provides fully internal manifolding of and separation of fuel and oxidant gases to each of the unit fuel cells in the fuel cell stack while providing reactant gas to reforming chambers interspersed along the cell axis to reform hydrocarbonaceous gas and supply enhanced hydrogen content to the fuel supply manifold.

Abstract: An optical fibre cable (6) for temperature detection comprises an optical fibre (13) and a temperature-responsive swellable body. The fibre (13) and the swellable body are held together by a helically-wound wire (14). The swellable body includes an elastic tube (11) which contains wax having a given melting point. When the wax melts, it expands in volume and causes the tube (11) to swell and therewith stretch the wire (14), resulting in the bending of the optical fibre (13). The fibre cable (6) is used in an OTDR-system. The propagation of light pulses (P) is measured and a heated section of the fibre cable (6) is detected through the detection of attenuated, reflected light pulses. A desired light attenuation in a range of from 0.01-0.1 Db/m can be obtained by appropriate selection of the parameter values of the fibre cable (6) for example the pitch (S) of the wire helix (14) and the volumetric expansion of the wax. This enables the locations of several heated sections along the fibre cable (6) to be established.
