Title: Vacuum dilution extraction gas sampling system and method
Inventor: TRAINA JOHN E
IPC: G01N33/00
Filed: 1993-07-29
Abstract: ABSTRACT        A gas sampling system utilizing a pair of parallel sonic orifices.  One of the orifices is connected to a source of filtered, heated samples.  The second, larger orifice is connected to a source of dilution gas.  A vacuum pump maintains a substantial vacuum behind the orifices, thus assuring critical flow therethrough.  The sample and diffusion gas are mixed behind the orifices and transported under partial vacuum for analysis.  The dew point of the sample is affected by both the ratio of the diameter of orifices and the degree of vacuum transporting the gas mixture.  As such, the dew point can be varied indefinitely by any reasonable combination of orifice ratio and vacuum pump strength.

IPC: G10L15/14
Filed: 1993-08-27
Abstract: A facility is provided for allowing a caller to place a telephone call by merely uttering a label identifying a desired called destination and to charge the telephone call to a particular billing account by merely uttering a label identifying that account. Alternatively, the caller may place the call by dialing or uttering the telephone number of the called destination or by entering a speed dial code associated with that telephone number. The facility includes a speaker verification system which employs cohort normalized scoring. Cohort normalized scoring provides a dynamic threshold for the verification process making the process more robust to variation in training and verification utterences. Such variation may be caused by, e.g., changes in communication channel characteristics or speaker loudness level.

Title: Method of reducing the level of contaminant materials in produced subterranean reservoir fluids
Inventor: CLIFFORD DENNIS A
IPC: E21B43/38
Filed: 1993-03-16
Abstract: A method is provided for reducing the concentration of radioactive materials or other trace contaminants in fluids withdrawn from subterranean reservoirs. The method involves deposition of sorbent solids within the reservoir matrix surrounding a production well to act as an in-situ filter for dissolved radionuclides or other contaminants present in reservoir pore waters. For this purpose, the sorbent solid is either a) precipitated within the reservoir matrix by the reaction of two or more carrier solutions or b) directly introduced into the reservoir as a solid component of a solid-liquid slurry using high-pressure injection techniques.  Thereafter, fluids produced by the well contain significantly lower concentrations of contaminants which are removed from the inflowing reservoir fluids by means of ion exchange, adsorption, chelation, chemisorption, or coprecipitation with the in-situ filter medium.

Title: Resin Coated Fastener and Apparatus and Method for Manufacture of Same
Inventor: DUFFY RICHARD J
IPC: B05D7/00
Filed: 1994-12-13
Abstract: An apparatus and method for applying a resin coating to a plurality of discrete portions of a fastener, such as both internal and external threads. A conveyor supports a fastener. The fastener is first transported past a heater and then past a first powdered resin spray assembly. Powdered resin, supplied to the first spray assembly by a resin reservoir, is used to generate a first air-borne powdered resin stream which coats one set of threads with resin when the fastener traverses the resin stream.      The conveyor also transports a second resin spray assembly through the first air-borne powdered resin stream. The second spray assembly uses a resin receiver to aspirate the air-borne resin. The resin is then used to generate a second powdered resin stream which coats the other set of fastener threads.

Title: Nonextractive processes for producing high purity aromatics
Inventor: INNES ROBERT A
IPC: C07C7/148
Filed: 1993-06-16
Abstract: Novel nonextractive processes for producing high purity and chemical grade aromatics (e.g., benzene, toluene, xylene) from hydrocarbon streams are described. For aromatic feedstocks containing close-boiling nonaromatic components, the stream is contacted with an acidic catalyst. As a result, nonaromatic impurities having boiling points in the aromatic range are catalytically converted to other species having boiling points substantially outside the aromatic boiling range. The desired aromatics in the product may be separated by simple distillation. Nonextractive processes incorporating a dual catalyst treatment are also described. Naphtha feeds are aromatized in a first stage by contact with a nonacidic catalyst, producing a mixture of aromatics and nonaromatic impurities with boiling points in the aromatic range. In a second stage, the mixture is contacted with an acidic catalyst under conditions that produce an effluent substantially free of nonaromatic impurities having boiling points in the aromatic range. High purity aromatics may be obtained by performing a simple distillation of the product.

Title: Antenna array with a continuous transverse stub element
Inventor: MILROY WILLIAM W
IPC: H01Q21/00
Filed: 1994-09-19
Abstract: A dielectric material is formed into a structure having two parallel broad surfaces with one or more raised integral portions extending transversely across at least one of the broad surfaces. The exterior is uniformly conductively coated resulting in a parallel plate waveguide having a continuous transverse stub element disposed adjacent one plate thereof. Purely reactive elements are formed by leaving the conductive coating on the terminus of the stub element, or by narrowing the terminus of the stub element.  Radiating elements are formed when stub elements of moderate height are opened to free space. Radiating, coupling and/or reactive continuous transverse stub elements may be combined in a common parallel plate structure in order to form a variety of microwave, millimeter wave and quasi-optical component including integrated filters, couplers and antenna arrays. Fabrication of the dielectrically-loaded continuous transverse stub element can be efficiently accomplished by machining, extruding or molding the dielectric structure, followed by uniform conductive plating in order to form the parallel plate transmission line. In the case of antenna applications, machining or grinding is performed on the stub terminus to expose the dielectric material at the end of the stub element.

Inventor: FITZGERALD MAURICE J
IPC: C08F8/00
Filed: 1994-10-27
Abstract: A photoreactive binder that may be used to enhance photospeed in either conventional plates or on-press developable lithographic printing plates.  Briefly, a polymer of m-isopropenyl-.alpha., .alpha.-dimethylbenzyl isocyanate is derivatized for vinyl group reactivity by reacting the isocyanate groups thereof with hydroxyalkyl acrylate. The resulting photopolymeric binder provides significantly higher photospeed than the non-reactive binder currently utilized in the production of conventional printing plates. The resulting lithographic printing plate also shows better durability (as manifested by longer run-length) and is more easily developed by the microencapsulated developers utilized in the present invention. As to the preparation of the photoreactive binders, the application discloses a method of copolymerizing m-isopropenyl-.alpha., .alpha.- dimethylbenzyl isocyanate (m-TMI) through complexation with an electron-deficient monomer such as maleic anhdride to accelerate free radical copolymerization with other monomers, and thus, provides greater monomer-to-polymer conversion. Use of the resulting product in the photoresist of a lithographic printing plate improves its adhesion to an underlying substrate.
