Abstract: METAL VAPOR ARC LAMP HAVING THERMAL LINK DIMINISHABLE IN HEAT CONDUCTION     ABSTRACT OF THE DISCLOSURE         A high pressure metal (sodium) vapor lamp comprises an outer vitreous envelope and an inner ceramic arc tube supported within it.  The arc tube contains vaporizable metal in excess of the quantity vaporized in operation and the heat balance determines a cold spot whereat excess metal collects.  The tem-perature of the cold spot determines the metal vapor pressure and the voltage drop across the lamp which must lie between specified limits.  A thermal link is provided to a metal member such as the exhaust tube the heat loss from which influences significantly the temperature of the cold spot. In completed lamps measuring too low in voltage, such thermal link may be partly severed without breaking open the outer envelope in order to raise the voltage.  One convenient way utilizes an auxiliary wire which is cut by aiming a laser beam at it.

Abstract: ABSTRACT     A stud arrangement on casehardened studded chains for motor vehicles, wherein the studs consist of a steel body which is permanently welded to a chain link and provided with a centrally disposed hard metal pin.  The hard metal pin is inserted into the steel body such that it is covered on all sides by steel material of a thickness which at least corresponds to the casehardening penetration depth.  In a method for producing such studded chains, an inwardly converging blind hole is cut out from one end of the steel body.          The hard metal pin, of a shape corresponding to the conical hole, is forced into the hole.  The pin is shorter than the blind hole so that a skirt is formed outside the pin.  The edge of the skirt is beveled, and the steel body with the hard metal pin is joined to the chain by resistance welding in a machine for welding studs onto chain links.  The body with the pin is moved gradually toward the chain link as the beveled edge melts and flows radially outwards during welding.  The studded chain is then case-hardened.

Granted: 1982-11-02
Abstract: ABSTRACT OF THE INVENTION        In the method of making a preform for a high numerical aperture gradient index optical waveguide, the concentration of two dopant constituents is changed during fabrication.  Concentration of the first dopant, G?O2 is changed radially as the preform is built up in order to produce the desired radial refractive index gradient.  The concentration of the second dopant, B2O3 is changed radially to compensate for the radical change in thermal expansion coefficient caused by the varying GeO2 concentration.  B2O3 is added to the cladding layer to make the thermal expansion coefficient of the cladding equal to or greater than the composite thermal expansion coefficient of the core.  The magnitude of residual tension at the inner surface caused by thermal expansion gradients is reduced and premature cracking of the preform is eliminated.

Abstract: ABSTRACT OF THE DISCLOSURE     A method and an optical sensing apparatus (1) are disclosed for measuring the polarization properties of light being scattered in the sky to obtain an accurate indication of visibility.  The intensities (I1 and I2) of two linearly polarized components of the daylight are measured, so that a polarization ratio (P) can be calculated to provide a visibility index by which visual quality and visual range can be determined.  The present method and apparatus may be extended to determine plume blight by comparing the polarization properties of light scattered by the plume with the polarization properties of the background sky, whereby theoretical visibility models may be validated.  In an alternate embodiment, another apparatus (30) may be utilized with a sensing system (46) that employs polarization modulation techniques, so that the polarization properties of the entire sky can be measured in the ultra-violet and infrared regions of the electromagnetic spectrum.          Accordingly, indications of both gas phase and particulate pollutant distributions in the atmosphere can be simultane-ously determined depending upon the magnitude of the polarization ratio (P) in regions of atmospheric pollutant absorption.

Abstract: FLOWLINE DEGASER     ABSTRACT    A Flowline Degaser (10) is provided which is positioned in a drilling operation between the bell nipple (24) and the shale shaker (34) and mud tanks (37).          The degaser (10) includes a structure defining a downwardly inclined surface (62) for dispersing drilling mud flowing thereover to remove gas.  The inclined surface also includes baffles (64) for agitating the drilling mud to remove additional gas.  The gas is removed through vent ports (68, 70) and into an upper expansion chamber (763 for disposal.  Blowers (82, 84) are positioned on the degaser for drawing a vacuum within the upper expansion chamber (76) and space (66) within the tank above the inclined surface to drive gas from the mud.  The vacuum is sufficient to affect the mud at the bell nipple to prevent accumulation of gas about the bell nipple.          This forms a significant safety factor in removing potentially explosive gas from the rig above the bell nipple.  If the drilling operation employs a blowout preventor, the vent line may also enter the degaser (10) for degasing of mud flowing therethrough.
