Abstract: An ultrasonic welding assembly comprising a horn, an anvil and an anvil cover. The horn comprises a generally T-shaped flattening surface and a rail projecting forward of the flattening surface. The rail is shaped to serve as a dam for flowing thermoplastic zipper material during stomping of slider end stops. The horn further comprises a plurality of vertical energy directors designed to direct ultrasonic energy into the mass of zipper material and deflect flowing zipper material toward the dam. The horn further comprises first and second recesses located on opposite sides of a stem of the T-shaped flattening surface. The anvil cover overlies opposing portions of the anvil and comprises a T-shaped cutout. The T-shaped flattening surface of the horn fits in the T-shaped cutout of the anvil cover. The resulting zipper has slider end stops located at opposing ends.

Abstract: The present invention relates to quinolines, pharmaceutical compositions containing them and their use as antagonists of urotensin II.

Abstract: Water management is improved in solid polymer electrolyte fuel cells by employing capillary channels or wicks in the lands that separate the reactant distribution channels in the flow fields. Capillary action moves water within these micro-sized capillary channels or wicks. Appropriate designs can be used to assist in the removal of water from the cell and/or in the redistribution of water from relatively wet regions in the cell to relatively dry regions.

Abstract: An apparatus for closing a slider-operated zipper on a moving filled package, comprising means for performing the following steps: conveying a package forward in a straight line; guiding a slider on a zippered portion of the package through a channel as the package moves forward; blocking forward movement of the slider at a predetermined position inside the channel as the package continues to move forward; and releasing the slider when the force being exerted by the slider in the forward direction reaches a level substantially equal to a predetermined threshold. This apparatus can be employed in association with a continuous band sealing apparatus. The means for blocking forward movement of the slider at a predetermined position inside the channel are a pair of spring-loaded plungers, e.g., ball plungers. If the slider end stop is weak, the slider will be pulled off the advancing package and will fall onto an ejection ramp.

Abstract: The present invention relates to novel quinolones and their use as urotensin antagonists.

Abstract: A nutrient formulation including moisture, a coloring agent, a palatability modifier, and/or an adjuvant which is designed for use in poultry and other animals, and a method of feeding it which improves subsequent livability, cumulative feed efficiency, weight gain, and resistance to disease challenge or other stresses is disclosed.

Abstract: The electrochemical performance of an ion-exchange membrane in a fuel cell system may be improved by impregnating therein a perfluoroamine. The amine may be primary, secondary or tertiary. Further, the amine is preferably water insoluble or only slightly water soluble. For example, the amine may be perfluorotriamylamine or perfluorotributylamine. Use of such a membrane system within a fuel cell may allow high or low temperature operation (i.e. at temperatures greater than 100° C. or less than 0° C.) as well as operation at low relative humidity.

Abstract: The present invention relates to a method of antagonizing the Urotensin-II receptor by 2-(NH-substituted) quinolones.

Abstract: A device for retrieving snagged lures has a rigid loop of stiff rod or wire mounted on a pole. The loop is made up of several portions placed in the same plane with one another and connected to a support portion mounted in the pole. The loop has first and second portions that define an acute angle between them at a corner for reaching over and grasping a lure for pulling it upward. A crossover portion completing the loop extends over the first portion and provides a tip for engaging a line and guiding it through a gap and into the loop. Also disclosed is a weighted device which is not connected to a pole, but which includes a similar loop.

Abstract: A tooltip corresponding to an object on a display screen is displayed on the screen in response to a cursor image being positioned over the object. The tooltip continues to be displayed as the cursor moves from the object to the tooltip, and the tooltip is removed from the screen when the cursor moves off both the object and the tooltip. A portion of the tooltip overlaps the object, so that the cursor can be moved from the object to the overlapping portion of the tooltip, and from the overlapping to the non-overlapping portion of the tooltip. A hyperlink may appear in the tooltip, which can be activated by positioning the cursor over the hyperlink in the tooltip and activating a switch or a button on a pointing device, such a mouse or trackball.

Abstract: An electrochemical fuel cell stack includes a plurality of fuel cells. At least one of the fuel cells is a sensor cell. The sensor cell has at least one structural dissimilarity with respect to the remaining fuel cells of the plurality. The structural dissimilarity may include, for example, a reduced sensor cell electrochemically active area, reduced electrocatalyst loading, modified anode or cathode flow field, different electrocatalyst composition, or a modified coolant flow field configuration. The sensor cell operates under substantially the same conditions as the remaining cells in the stack. However, in response to a change in a particular stack operating condition, an electrical or thermal response, preferably a voltage change, is induced in the sensor cell which is not simultaneously induced in the remaining fuel cells. Thus, the sensor cell can detect undesirable conditions and its response can be used to initiate corrective action.

Abstract: An material level monitoring and reporting system uses special micropower impulse radar level sensing probes, with one such probe being inserted into each of a plurality of material containment structures, such as storage tanks. The micropower impulse radar probes use flexible waveguides which extend downward to the tank bottom such that micropower radar impulses travel to and from the liquid surface via a wave guide, with the lapse between emission and reception of the impulse indicating a distance from the probe, and thus a liquid level. Each level sensing probe is connected to a communication link which collects level and status information from the level sensing probes and transmits it to a monitoring site. The material level data may be collected from a plurality of intermediate monitoring sites by a central monitoring sites.

Abstract: Flexible zippers having sculpted slider end stops and reclosable packages incorporating such slider-operated zippers. In one embodiment, the flexible zipper comprises a joined end and a slider end stop that projects laterally beyond a side surface of the major portion of the zipper. The slider end stop is integrally formed with an adjoining portion of the joined end. In another embodiment, the flexible zipper comprises a joined end and a slider end stop that projects upward to an elevation higher than an elevation of a top surface of the major portion of the zipper and is laterally offset relative to a vertical midplane of the zipper. This slider end stop is also integrally formed with an adjoining portion of the joined end. These structures can be combined to form an end stop that projects upward and laterally outward. Each end stop is asymmetric relative to a vertical midplane of the zipper.

Abstract: A videoconference system uses an Internet Protocol (IP) based communication channel for a video portion of the videoconference and uses a Public Switched Telecommunication Network (PSTN) as an audio communication channel for an audio portion of the videoconference. The videoconference system uses a digital communication channel for a video portion of the videoconference and uses a Public Switched Telecommunication Network (PSTN) as an audio communication channel for an audio portion of the videoconference and the system integrates with an automatic call distribution system of a call center. The digital based communication channel may be used for data communication. The videoconference system may interface with a database that stores customer information.
