Filed: 1998-04-09
Abstract: A color translating UV microscope for research and clinical applications involving imaging of living or dynamic samples in real time and providing several novel techniques for image creation, optical sectioning, dynamic motion tracking and contrast enhancement comprises a light source emitting UV light, and visible and IR light if desired. This light is directed to the condenser via a means of selecting monochromatic, bandpass, shortpass, longpass or notch limited light. The condenser can be a brightfield, darkfield, phase contrast or DIC. The slide is mounted in a stage capable of high speed movements in the X, Y and Z  dimensions. The microscope uses broadband, narrowband or monochromat optimized objectives to direct the image of the sample to an image intensifier or UV sensitive video system. When an image intensifier is used it is either followed by a video camera, or in the simple version, by a synchronized set of filters which translate the image to a color image and deliver it to an eyepiece for viewing by the microscopist. Between the objective and the image intensifier there can be a selection of static or dynamic switchable filters. The video camera, if used, produces an image which is digitized by an image capture board in a computer.  The image is then reassembled by an overlay process called color translation and the computer uses a combination of feedback from the information in the image and operator control to perform various tasks such as optical sectioning and three dimensional reconstruction, coordination of the monochromater while collecting multiple images sets called image planes, tracking dynamic sample elements in three space, control of the environment of the slide including electric, magnetic, acoustic, temperature, pressure and light levels, color filters and optics, control for microscope mode switching between transmitted, reflected, fluorescent, Raman, scanning, confocal, area limited, autofluorescent, acousto-optical and other modes.

Abstract: The invention relates to a device comprising at least one safety shut-off control valve. A safety valve is optionally connected to said safety shut-off control valve, connected in series in the fluid flow path. In the safety shut-off control valve, a sealing valve is returned to a sealing position against a seat by means of a return spring, and is controlled by a linear actuator and a connecting rod for continuous adjustment of the valve opening. The connecting rod comprises two independent segments which are at least partially made from a ferromagnetic material and which are magnetically coupled to a magnetic coupling circuit that is activated by a coil. While electric power is being supplied to the coil, the magnetic field that said coil creates maintains the linking rod segments coupled to one another, such that the linear actuator can control the sealing valve. Once the power being supplied to the operating coil is interrupted, the segments separate and the sealing valve returns to said sealing position regardless of the position of the linear actuator. At the same time, the check valve of the safety valve is pushed back to the sealing position by a return spring. In this way, a continuous control valve with a double safety system is produced.

Filed: 2002-05-31
Abstract: A method and an apparatus for advantageously introducing a flame and a high velocity oxidizing gas into a furnace for metal melting, refining and processing, particularly steel making in an electric arc furnace. The steel making process of an electric arc furnace is made more efficient by shortening the time of the scrap melting phase and introducing an effective high velocity oxidizing gas stream into the process sooner to decarburize the melted metal.  In one implementation of an apparatus, improved efficiency is obtained by mounting a fixed burner/lance closer to the hot face of the furnace refractory at an effective injection angle. This mounting technique shortens the distance that the flame of the burner has to melt through the scrap to clear a path to the molten metal and shortens the distance the high velocity oxygen from the lance travels to the slag-metal interface thereby increasing its penetrating power. The method additionally includes supplying a plurality of reaction zones with the high velocity oxidizing gas to decarburize the melted metal.  The plurality of reaction zones increases the surface area available for the reaction thereby allowing a more rapid rate of decarburization and a more homogenous metal bath. The reaction zones are supplied with the high velocity oxidizing gas according to an oxygen supply profile which is related to the carbon content of the metal bath. In this manner an optimal amount of oxygen can be introduced into the metal bath to shorten the decarburization process without producing excessive oxidation of the metal bath and excessive free oxygen in the furnace.
