Abstract: These devices are characterised by the use of mechanical and pneumatic members equipping the sheet-by-sheet press with different functions whether the sheet-by-sheet or continuous-web printing method is adopted. In another form of the invention, the toggle 14B, Figure 1, for operating the suckers 13, its axle 14A and the axle of the levers of the toggle 14B make it possible, in sheet-by-sheet printing, to extract the sheet from the stack 9 or, in continuous-web printing, by replacing the suckers 13 with the movable suction tube 31, Figure 2, to move the web 24 backwards in order to obtain its refeed between each printing cycle. A removable frame 34, Figure 2, works jointly with the pneumatic refeed devices and is located at the entrance of the press. A receiving table 45 of constant level consists of a parallelogram, the weight of which is compensated by a spring 47. The device processes equally continuous webs 24, Figure 2, for prefolded forms perforated with "Caroll" holes or a continuous web 24A, Figure 9, in the form of a reel 70 rewound 79 after printing.

Abstract: Un procédé de mise en oeuvre pour le test en fonctionnement d'un dispositif de visualisation d'informations radar, tel qu'un transformateur numérique d'images consiste essentiellement, dans un premier temps, à déterminer des zones où il n'existe pas d'écho pour un tour d'antenne donné puis, dans un second temps, connaissant les vitesses des objets visualisés, à déterminer une seconde zone où, de façon certaine, il n'existera pas d'écho au tour suivant. Dans une troisième étape, on insère dans la seconde zone une séquence de test; en sortie de la fonction sous test, les données correspondant à la séquence sont d'une part enregistrées et d'autre part occultées pour non-transmission au reste de la chaîne. La séquence de sortie enregistrée est ensuite comparée au résultat théorique attendu, comparaison d'où on déduit une information de bon ou mauvais fonctionnement.

Inventor: JACOBSEN STEPHEN C
IPC: G01R29/12
Filed: 1988-07-05
Abstract: Sensor systems and methods for detecting the position and/or movement of an object in multiple degrees of freedom. The sensor system of the present invention comprises at least one field-effect transistor (FET), the geometrical configuration of the FET being selected so as to provide the desired sensitivity. The FET is preferably provided with a conductive gate adjacent to but insulated from the channel region of the FET. An object whose position and/or movement is to be detected is prepared such that an electric field emanates from the object. The FET is brought into the vicinity of the object, and the electric field emanating from the object interacts with the gate and/or channel region of the FET so as to modify the magnitude of the electrical current flowing through the channel region. The current through the channel region is detected and is used to obtain information about the position and movement of the object relative to the channel region of the FET. By positioning a plurality of substantially coplanar FETs in the vicinity of the object, the position and/or movement of the object in any desired number of degrees of freedom can be detected and monitored.

Abstract: A process for producing molten stainless steel by continuously subjecting Cr materials such as Cr ores or Cr pellets to melt reduction and decarbonization in one vessel at high treating speeds, which comprises, in the melt reduction, blow­ing an inert gas or the like through a bottom-blown tuyere to form projections on the molten metal surface and blowing an inert gas or the like against the projections through a side-blown tuyere to diffuse the molten metal into a Cr material-­floating zone in the slag for accelerating the reduction of the Cr material with C contained in the molten metal and, on the other hand, blowing O₂ for decarbonization into the molten metal through a top-blown lance and O₂ for secondary com­bustion into the slag to form a secondary combustion zone mainly in the slag, and vigorously stirring the slag by the side-­blown gas to give a heat produced by the secondary combustion to the Cr ores with high efficiency while keeping a second combustion ratio at 0.3 or more for assuring high secondary combustion and, after the melt reduction, discharging the slag and top-blowing O₂ for decarbonization diluted with an inert gas and blowing an inert gas through the bottom-blown tuyere to vigorously stir the molten metal.   
     SUMMARY OF THE INVENTION 
     This invention relates to a method of producing stainless molten steel by a smelting reduction treatment - decarburization treatment of Cr raw materials such as Cr ores, Cr ore pellets and so on consecutively and at high treating speed in one container. In the smelting reduction, an inert gas is blown from bottom tuy­eres to form an upheaving part of the molten metal on its surface and the inert gas is blown to this upheaving part. The molten metal is thereby caused to disperse into a region of the slag where the Cr materials float, so that the reduction of Cr is accelerated by C. On the other hand, decarburizing O₂ is blown into the molten metal from a top lance, while O₂ for a post com­bustion is blown into the slag, so that a post combustion region is formed mainly in the slag, and the slag is forcibly agitated by blowing the gas from the side tuyere, so that a heat generated by the post combustion is caused to transfer to Cr ores at high heat transfer efficiency, and a high post combustion is secured, as maintaining the post combustion ratio to be more than 0.3. After having completed the smelting reduction, the slag is dis­charged. The molten metal is agitated complusively by blowing the decarburizing O₂ diluted with the inert gas from the top lance, and blowing the inert gas from the bottom tuyeres.

Abstract: Moderne Schaltnetzteile enthalten einen integrierten Baustein (IS), der die Ansteuerung des Schalters (7) übernimmt. Dieser Baustein (IS) wird häufig in seinem inaktiven Zustand über einen Anlaufwiderstand (14) und in seinem aktiven Zustand, in dem alle Arbeitspunkte eingeschaltet sind, von einer Transformatorwicklung (15) mit der erforderlichen Spannung (UV) versorgt. Liegt am Baustein (IS) ein Abschaltbefehl (UAB) an, so wird der Schalter (7) nicht eingeschaltet, mit der Folge, daß der Baustein (IS) in einen Abfragebetrieb übergeht, in dem er mit einer durch die Kapazität des Ladekondensators bestimmten Periode zwischen seinem inaktiven und aktiven Zustand pendelt. Um nun den Baustein (IS) bei Wegnahme des Abschaltbefehls (UAB) sofort in den aktiven Zustand zu bringen, wird vorgeschlagen, den aktiven Zustand bei Vorliegen eines Abschaltbefehls (UAB) zu blockieren. Dann kann nämlich der Kondensator (13) bei Wegfall des Abschaltbefehls (UAB) sofort die zum Aktivieren erforderliche Versorgungsspannung (UV) abgeben.

Abstract: A finger sensor for a pulse oximetry system comprising a body of flexible, resilient polymeric material formed as a pocket. On the inside walls of the pocket towards the closed end are situated a LED light source (18) and an opposing photodetector (22). The space within the pocket is divided into a central region (54) and lateral regions (30, 32). As a finger is inserted into the pocket with the fingertip between the LED and the photodetector, the central and lateral regions of the pocket expand, causing the walls of the pocket containing the LED and the photodetector to securely contact and retain the finger within the pocket. Due to the resilience of the material the pocket walls may expand and contract to engage fingers of varying sizes.
