Title: Liquid alkylated diphenylamine antioxidant
Inventor: LAI JOHN T
IPC: C10N30/10
Filed: 1997-05-29
Granted: 2006-02-21
Abstract: A process for monoalkylating diphenylamine using a clay catalyst is disclosed which results in a reaction product having substantial amounts of desirable monoalkylated diphenylamine and minimal amounts of less desirable disubstituted diphenylamine and unsubstituted diphenylamine. The disclosed process uses clay catalysts which favor monoalkylation over dialkylation and specific conditions such as reaction temperature, mole ratios of alkylating olefin to diphenylamine, reaction times, and catalyst amounts. Preferred olefins are diisobutylene and linear alpha olefins having from 6 or 8 to 18 carbon atoms. When more than 1 wt.% residual unreacted diphenylamine is present it may be converted to alkylated diphenylamine by reacting with styrene, alpha-methylstyrene or isobutylene.

Abstract: A process is disclosed for the shut-down of a membrane separation zone comprising a non-permeate side and a permeate side and processing a feed stream comprising a non-permeable component, a less-readily permeable, condensible component, and a readily permeable component. When the feed stream is not passed to the membrane separation zone, a purge stream is passed at a relatively higher pressure to the non-permeate side of the membrane separation zone to remove a residual gas stream and thereby prevent condensation of the less-readily permeable, condensible component upon depressurization and/or cooling of the membrane separation zone. The invention reduces the need for oversizing membrane system which reduces treating costs and prevents permeate damage to membrane surfaces caused by condensation of less-readily permeable, condensible components such as C6+  hydrocarbons.

Abstract: A scintillating optical fiber sensitive to low energy radiation has a clear, solid, elongated core with a thin cladding layer surrounding substantially all of the core along substantially all the length of the core and a dye dopant dispersed within the thin cladding layer. When a low energy radiation particle contacts the thin cladding layer, energy from the particle is transferred to photons having a radiant energy frequency determined by the dye dopant color, and a fraction of the photons are transmitted through the fiber by total internal reflection. A detector using the scintillating optical fiber is also disclosed having sensor means for detecting and indicating the presence of photons operatively connected to an end of at least one optical fiber, such that when the fraction of photons are transmitted through the fiber by total internal reflection to the end, the sensor means detects the photons and subsequently provides an indication that low energy radiation has been detected.

Abstract: A container assembly for housing liquid products and a prize therein which may be distributed with non-prize bearing containers comprising: a can for containing the liquid product in an interior chamber thereof, and a prize-holding subassembly positioned within the interior chamber for retaining a prize therein. The prize holding subassembly includes a tether (60) for supporting the prize assembly. The tether includes a hair-pin shaped spring portion (66) defining legs, and foot portions (64, 68) extending from those legs. A proximal end of the tether on one of the foot portions engages a gate (46) on the underside of the can closure, and compresses the spring portion into a cocked position. When the closure is opened, the gate releases the proximal end of the tether so that it may pop up through the open end of the can for gripping by the consumer. A distal end of the tether on the other end of the tether supports a prize container which is manually removable from the can with the tether.

Abstract: The present Invention is an improved method and tool for determining formation density by using an array of gamma-ray detectors. This invention can correct for large standoffs encountered in abnormally shaped boreholes and in particular for the increased standoffs typically encountered by mandrel tools. In this invention the collimated detectors have varying depths of investigation into the formation. At small standoffs a short spaced (SS) detector investigates mainly the mud and mudcake and a shallow layer of the formation. Unlike the SS a mid spaced (MS) detector has a deeper depth of investigation and is sensitive to borehole and formation even at increased standoffs. A long spaced (LS) detector is mainly sensitive to the formation density and its density reading is corrected by using the standoff information from the MS and SS detectors. In addition to measuring density this invention can measure the photo-electric factor (PEF) of the formation. Because photo-electric absorption preferentially removes low energy gamma-rays the tool housing needs to allow passage of low energy gamma-rays. This can be accomplished through the use of a window of a material with a low atomic number (Z) or through the use of a low-Z housing material like titanium. Typical window materials are beryllium and titanium. Housing materials can be titanium or for lower pressure requirements graphite or high-strength carbon compounds.

Abstract: This invention involves a new type of feedthrough-plug member for metal halide HID lamp using PCA envelopes. The construction of the lamp housing consists of a PCA envelope and specially designed radially graded alumina-metal cermet multilayers to eliminate cracking in cermet or PCA due to thermal stresses arising from thermal expansion mismatch. The fills are metal halides such as Na-Sc-I, rare earth halides, Hg, Sn, and inert gases. The PCA vessel and directly sealed cermet-feedthrough assemblies allow the metal halide lamps to operate at high wall temperatures with better lumen output, color temperature, and CRI.

Abstract: Features of subsurface earth reservoirs of interest are made available for analysis by forming three-dimensional, geologic block models (Fig. 4) based on field data. The field data include geological observations, such as lithofacies and porosity values (204) obtained from well data and other sources, as well as geophysical data, usually from seismic surveys. The geologic models representative of subsurface reservoirs so obtained are optimized to match as closely as feasible geologic constraints (116) known or derived from observed geologic data. The models also conform to geophysically based constraints indicated by seismic survey data. The modeled geologic lithofacies and porosity are converted into acoustic velocity and bulk density values, which are then formulated as a seismic response which is then compared with actual seismic data. A perturbation process (246) on lithofacies and porosity can be iteratively repeated until a representation of the reservoir is obtained which is within limits of accuracy or acceptability.

Abstract: A method for analysing a thermal paint includes the step of defining a colour space in at least two dimensions, the dimensions representing different colours and/or luminance values. The location of reference points, representing calibration data, is defined within the colour space for comparison with colour information relating to a part to be analysed. Each pixel of an image of the part to be analysed is given a location in colour space and the nearest calibration reference point is determined. In this way, the approximate temperature of that point can be established.

Abstract: A UV weatherable film (1) con-struction is provided which is capable of retaining its dimensional stability under extreme environmental temper-atures and humidities. The base film polymer, syndiotactic polystyrene (3), has characteristically low moisture ab-sorption, excellent thermal stability, and high transparency. When used in combination with a UV-blocking coating (5), the sPS film exhibits a degree of resistance to UV-induced discoloration and degradation that is substantially superior to unprotected sPS films or films based on sPS resins that are merely compounded with UV absorber. The sPS cover films of the present invention are useful as overlay films in signing (1) and other outdoor applications, are comparable to UV-absorber loaded acrylic films in UV blocking or resistance, and provide a cost competitive alternative to acrylic, polyester, and fluoropolymer overlay films.
