Abstract: Various methods and devices are provided for allowing multiple surgical instruments to be inserted into sealing elements of a single surgical access device. The sealing elements can be movable along predefined pathways within the device to allow surgical instruments inserted through the sealing elements to be moved laterally, rotationally, angularly, and vertically relative to a central longitudinal axis of the device for ease of manipulation within a patient's body while maintaining insufflation.

Abstract: A system and method for generating visual or multimedia search results in response to an Internet document search query. HTML documents are retrieved from the Internet and keywords are extracted from the HTML documents based on the structure of the HTML documents and the HTML documents' metatags. The HTML documents are scanned for representative non-textual content such as images or audio files. The HTML documents' locations, extracted keywords, and representative non-textual content are stored in data records in a database for future use. The database is used to create a search result HTML document containing the representative non-textual content.

Abstract: A combine grain bin monitoring system includes a pair of detectors mounted on the upper edges of opposing side walls of a combine grain bin, for detecting the presence of grain. A visual display module mounted outside of the bin has a visual indicator which is operable in response to a signal received from either of the detectors. A third detector is preferably mounted on the upper end of a support located generally centrally within the bin, and is also electrically connected to the visual indicator such that the visual indicator will operate in response to a signal from either of the side wall detectors or the central detector. Additional detectors may be added to the central support to signal the level of grain within the bin. A visual alert device is electrically connected to the visual display module but spaced remote therefrom. The visual alert device is operable in response to the illumination of a lamp on the visual indicator.

Abstract: A method for automatically updating a speed calling data base in a telecommunications network entails tagging an outgoing speed call with a speed calling tag, identifying the telephone number of a speed call as being non-working, retrieving the updated telephone number, and replacing the non-working number in the speed calling data base with the updated number based on update options selected by the calling party. All occurrences of the non-working number could be replaced depending upon options selected by subscribers being served from the speed calling data base.

Abstract: An optical inspection system and method for detecting flaws on a diffractive surface such as a reticle or wafer, includes illuminating a surface to be inspected to generate a first scattered energy angular distribution in response to a flaw on the surface and a second scattered energy angular distribution in response to an unflawed surface; the first and second energy distributions are sensed and the minimum energy detection energy level is established; determining whether the minimum detected energy level is in a first or second predetermined energy range and indicating that no flaw is present when the minimum detected energy level is in the first range and a flaw is present when the minimum detected energy level is in the second range.

Abstract: A breeder reactor fuel element having a tandem arrangement of fissile and fertile fuel with a getter for fission product cesium disposed between the fissile and fertile sections. The getter is effective at reactor operating temperatures to isolate the cesium generated by the fissile material from reacting with the fertile fuel section.

Abstract: Process for the production of undegraded alkylated aromatic compounds by alkylating an aromatic compound with a C.sub.3 or higher olefin polymer having terminal ethylene units.

Abstract: A nuclear reactor fuel element is described which has an outer cladding, a central core of fissionable or mixed fissionable and fertile fuel material and a layer of oxygen gettering material on the inner surface of the cladding. The gettering material reacts with oxygen released by the fissionable material during irradiation of the core thereby preventing the oxygen from reacting with and corroding the cladding. Also described is an improved method for coating the inner surface of the cladding with a layer of gettering material.

Abstract: The addition of a small quantity of barium to liquid metal NaK or sodium has been found to promote foam formation and improve bubble retention in the liquid metal. A stable liquid metal foam will provide a more homogeneous liquid metal flow through the channel of a two-phase liquid metal MHD power generator to improve operating efficiency.

Abstract: A process of preparing an alkylated phenol which is substantially monoalkylated and para oriented which comprises reacting phenol with a C.sub.4 -C.sub.9 olefin and wherein said olefin is utilized in about 5-10% stoichiometric excess. The broad reaction temperature utilized is about 60.degree.-105.degree. C and the time of reaction is at least 30 minutes. The catalyst utilized is anhydrous H.sub.3 PO.sub.4 which is used in a value of at least 8% based upon the weight of reactant phenol. The preferred products are p-t-amylphenol and p-t-butylphenol, and in the process of preparing these preferred phenols, the olefin may be reacted in 5-8% stoichiometric excess and the reaction temperature utilized may be 95.degree.-115.degree. C. An additional preferred product is p-nonylphenol derived from a branched propylene trimer.

Abstract: A nuclear reactor fuel element is described which has an outer cladding, a central core of fissionable or mixed fissionable and fertile fuel material and a layer of vanadium as an oxygen getter on the inner surface of the cladding. The vanadium reacts with oxygen released by the fissionable material during irradiation of the core to prevent the oxygen from reacting with and corroding the cladding. Also described is a method for coating the inner surface of small diameter tubes of cladding with a layer of vanadium.

Abstract: In the alkylation of naphthalene using an alkene reactant to produce monoalkyl naphthalene, the inhibition of polyalkyl and specially dialkyl naphthalenes by the use of a mixed protonic acid catalyst consisting of methane sulfonic acid and an active P.sub.2 O.sub.5 containing acid, utilized in about a 2:1 to 1:2 ratio with an optimum ratio of about 1:1. The reaction is carried out preferably under anhydrous conditions with respect to the mixed catalyst, and the products show present utility as emulsion breakers in petroleum chemistry as well as other surface active agents.

Abstract: A breeder material for use in a breeder blanket of a nuclear reactor is disclosed. The breeder material comprises a core material of lithium containing ceramic particles which has been coated with a neutron multiplier such as Be or BeO, which coating has a higher thermal conductivity than the core material.
