Title: Method and apparatus for engraving a mark on plane of curved surfaces
Inventor: WYSSEN HANS
IPC: B44B3/06
Filed: 1994-01-21
Abstract: METHOD AND APPARATUS FOR ENGRAVING A MARK ON PLANE     OR CURVED SURFACES            Abstract: An apparatus and method for engraving selected indicia into surfaces of structures (18) for identification purposes comprising a stencil (9) , and a scribe (16) with a hard point . The stencil consists of a stencil body (10) made of a durable, flexible material having a pressure sensitive adhesive backing (14) for the purpose of securing the stencil to the surface to be marked during the engraving operation. After the stencil (9) is affixed to the surface to be marked (18), the engraving is accomplished by manually moving the tip of the engraving scribe (16) within the indicia apertures (12) of the stencil, thereby engraving the surface with marks corresponding to the indicia apertures.

Inventor: SASAKI HIROSHI
IPC: G03G9/08
Filed: 1994-02-08
Abstract: A toner has a narrow toner particle size distribution and particles of deformed spherical shape. There is also a simple manufacturing method for the toner and an imaging apparatus using the same. The toner particles are characterized in having an average diameter of d (d is in a range of 4-15 µm), and that the volumetric fraction of the particles having a diameter in a range of d ~ 0.2d is equal to or exceeds 90% of the total volume of the particles. Further, when the specific surface area of the toner per 1 cm3 determined by the BET method is expressed by A (m2/g) and the specific gravity of the particles is expressed by D (g/cm3), the A of the particles is in a range expressed by the equation, 7/(D~d) ~ A ~ 10/(D~d).      The toner provides improved resolution of the image.

Title: Helicopter integrated fire and flight control having constraint limiting control
Inventor: FOWLER DONALD W
IPC: F41G3/12
Filed: 1993-04-26
Abstract: During operation of an integrated fire and flight control (IFFC) system in a coupled aiming mode, the occurrence of a weapon (172), weapon mount (145) or sensor (146) reaching a constraint limit (210) induces a fade-in of a constraint limiting axis command signal (140) for a respective attitude axis as the aircraft attitude reference, replacing the flight control system attitude feedback error signal (111) for the respective attitude axis. The constraint limiting axis command signals provide the aircraft attitude reference only while the pilot manually depresses and holds an enable switch (920). The pilot command stick input (90) remains the primary input to the IFFC system to thereby provide override capability for pilot command maneuvers.

Title: Evaporation vessel and electrode arrangement for an electrode evaporator
Inventor: GRIEDER HEINER
IPC: F22B1/30
Filed: 1994-03-22
Abstract: Abstract A  refinement  of  an  evaporation  vessel  and electrode arrangement is proposed which allows a large range of different apparatus types to be provided, of variable construction, using a small number of different components. For this purpose, an arrangement of a plura-lity of bushings (16.1, 16.2) is provided in the wall of the evaporation vessel  (2,  6,  10),  in which bushings (16.1, 16.2) electrodes (20) can be held by means of a plug-in part (18). The plug-in part (18) is provided with an automatic latching device  (38,  40)  which holds it firmly after simple insertion into one of the bushings (16.1, 16.2) and which can be released again by hand, if required, in order to remove the plug-in part. Electrodes can thus be installed at various positions and in dif-ferent orientations in a simple manner, depending on the desired design of the electrode evaporater. It is fur-thermore proposed to include in the electrode arrangement a dummy electrode which is electrically not connected or is connected to a neutral conductor. Using such a dummy electrode,  the  behaviour  of  the  electric  field  can additionally be controlled, so that the other (active) electrodes require less matching to different apparatus designs, or do not need any matching at all.

Inventor: RICCARDI GUY
IPC: H03D3/00
Filed: 1992-09-04
Abstract: 2120344 9307676 PCTABS00162 L'invention concerne les procédés qui permettent de démoduler de manière numérique une modulation complexe permettant de transmettre des paramètres différents. Elle consiste à effectuer un filtrage en bande de base (201) du signal d'entrée, une démodulation complexe (202) d'une première sous-porteuse à la fréquence Fp pour obtenir après élévation au carré (207) un signal de correction. On démodule ensuite le signal d'entrée autour d'une fréquence exactement égale au double de la fréquence de la première démodulation pour obtenir des signaux de sortie présentant une erreur de fréquence par rapport à 2Fp. Cette erreur de fréquence est corrigée par multiplication (213) avec le signal de correction de fréquence élaboré précédemment. On filtre ensuite (214, 215) à une fréquence inférieure à 1 Hz le signal ainsi corrigé pour obtenir un signal donnant l'erreur de phase à la fréquence 0, c'est-à-dire celle de la sous-porteuse à 2Fp. Ce signal permet de corriger en phase les signaux préalablement corrigés en fréquence pour obtenir deux signaux complémentaires l'un de l'autre et transmis par modulation en quadrature autour de la fréquence 2Fp. Elle permet de démoduler les signaux omnidirectionnels et dipolaires provenant d'une bouée d'écoute sous-marine.

Title: Absorbent material and method of making same
Inventor: BRASSINGTON NIGEL J
IPC: D04H1/485
Filed: 1993-04-29
Abstract: An absorbent material suitable for use as a medical or hygienic absorbent and comprises a non-woven fibre sheet having dense surface layers (10) and between these layers a less dense region where most of the fibres extend in the plane of the sheet.  Transversely extending fibres (16) help to bind the material, the fibres also being bonded to some extent by a hot melt bonding material, e.g. core/sheath-type bi-component fibres. The material is made by forming a blend of fibres, including a minor weight of hot melt fibres, by cross-lapping a plurality of layers (14) to form a web, subjecting the web to needling at low punch density with penetration through the web, thereafter subjecting surface regions (10) of the web to higher punch density needling to form the dense surface layer (10) at each face from the web. The web is then heated, e.g. by high temperature air, to soften the hot melt material and to cause it to bond adjacent fibres while retaining its fibrous form and without significant shrinkage of the web as a whole.

Abstract: Improved asymmetrical microporous hollow fibers incorporating a low molecular weight surfactant and the process for the production of the hollow fibers are disclosed. The hollow fibers have significantly improved flux and rewetting characteristics. The process involves passing a polymeric solution through an outer annulus of die to create an annular stream and a precipitating fluid through the inner orifice of the die creating a stream within the annular stream resulting in hollow fiber formation. The pro-cess further involves incorporating a low molecular weight surfactant into the hollow fibers at any one of several stages during the process.
