Abstract: A component for a gas turbine engine, including: at least one internal cavity extending through the component, the internal cavity having at least one inlet opening and at least one outlet opening each being in fluid communication with the at least one internal cavity; a plurality of cooling features extending from a surface of the at least one internal cavity, the plurality of cooling features are formed in accordance with at least one of the following groups: i) a plurality of airfoil shaped features that extend upwardly from the surface of the at least one internal cavity and a plurality of wedge shaped features each having a triangular base that has an upstream portion and a downstream portion, the upstream portion extending further from the surface than the downstream portion; ii) a plurality features having a curved or “J” shaped base that extends upwardly from the surface, a plurality features having a double curved or symmetrically “J” shaped base that extends upwardly from the surface, and a pluralit

Abstract: A gas turbine engine includes a turbine section that has a retainer ring, a first vane that bears against the retainer ring to prevent movement of the first vane in a first axial direction, a second vane axially spaced from the first vane, and a blade axially between the first vane and the second vane. A blade outer air seal is situated radially outwardly of the blade. The blade outer air seal includes a ceramic matrix composite body that defines a core gaspath side that faces the blade, a forward end, an aft end, and circumferential sides. There is a spring seal at the aft end of the blade outer air seal that seals against the second vane. The spring seal provides a preload that biases the blade outer air seal against the first vane and thereby biases the first vane against the retainer ring.

Abstract: A gas turbine engine includes a turbine section that has a ceramic matrix composite body that defines a core gaspath side that a row of blades, a forward end, an aft end, and circumferential sides. The forward end abuts at least one vane of a first row of vanes, and the aft end including a seal channel. A compliant seal is disposed in the seal channel and seals against at least one vane of a second row of vanes.

Abstract: A sustained-release, dental fluoride varnish material includes about 5 percent by weight of NaF; up to about 10 percent by weight of glycerin; up to about 5 percent by weight of fumed silica; and optionally, an amount of varnish additives selected from the group consisting of flavorants, rosins, gums and alcohols.

Abstract: A dental tooth whitening material sets to a rubber-like or elastomeric consistency. The material includes hydrogen peroxide. A method of whitening teeth employs such a material by placing it into a dental tray, a backing sheet or by placing the material directly onto a tooth. Once the material has set to its solid or semi-solid consistency, the dental tray, if employed, can be left in place or removed.

Abstract: A method, system, computer program product, and data structure for trading in which a standardized contract is traded. The contract obligates a buyer and a seller to settle the contract based on a price of the contract at a first effective date. The contract is traded through an exchange that guarantees payment to the buyer of any amount owed to the buyer from the seller as a result of the contract and that guarantees payment to the seller of any amount owed to the seller from the buyer as a result of the contract. The price of the contract is determined based on preselected notional cash flows discounted by at least one point on an interest rate swap curve obtained from a preselected swap rate source.

Abstract: An oral prophalaxis paste includes a preselected grade and amount of abrasive material such as pumice clay or diatimoceous earth. The abrasive material is moistened with water and a moisture retention agent such as glycerin is included. A curing system is employed, such as using sodium silicate and methyl salicylate. The formulation provides antimicrobial properties by the inclusion of triclosan.

Abstract: An improved electronic mass airflow sensor circuit and method for manufacturing that circuit are disclosed. The circuit includes primary and secondary sensor elements having non-zero temperature coefficients of resistance. The circuit further includes a thick film resistor electrically connected to the secondary sensor element to form a combination element such that resistance ratio of the primary sensor element to the combination element remains constant over varying temperatures. The method includes the steps of detecting the resistance of the primary and secondary sensor elements, generating primary and secondary electrical signals corresponding thereto, and placing the thick film resistor in electrical contact with the secondary sensor element to form the combination element.

Abstract: A mass air flow sensor is calibrated by exposing it to known air flow and measuring the input and output voltage to a calibratable output stage. In the absence of air flow, the output stage is then calibrated to produce a desired output voltage in response to an application of the measured input voltage.

Abstract: A method for calibrating the response time of a mass air flow sensor in which the sensors bridge offset voltage is measured and the constant C.sub.I is calculated from the initial value of the bridge offset voltage. C.sub.I is a constant of the heated resistor's resistance in the equation RH=C+(1/I.sub.H) C.sub.I. The response time of the mass air flow sensor is a function of C.sub.I. A bridge offset voltage required to give C.sub.I a desired value is calculated. A pair of biasing resistors are trimmed while monitoring the value of the bridge offset voltage until the monitored value of the bridge offset voltage is equal to the desired value.
