Abstract: Compounds of Formula (I), wherein R1, R2, R3, R4, R5, R6, T, W, X, Y and Z are as defined herein are provided, together with pharmaceutically acceptable salt, hydrates and/or prodrugs thereof.

Abstract: A transporting and feeding package for a coil of welding wire comprising a wire receiving container with a vertical wall having a lateral shape and defining an opened top of the container, a wire feeding hat with a wire outlet and a downwardly extending skirt having a lower end with an opening and having a shape matching, but slightly larger than, said lateral shape so the skirt can move vertically along the vertical wall between a lowered transporting position and a raised feeding position while extending over said opened top of the container.

Abstract: An interactive, multi-media game system and method is provided. In a preferred embodiment, an audio and/or visual playback system contains portions of a prerecorded narrative stored therein. Teams of players cooperatively solve puzzles, obtain information fragments and directional clues, and ultimately solve an overall meta-puzzle that can be in the context of the narrative. The players move between the portions of the prerecorded narrative and the puzzles that are positioned at selected locations in a defined space. The players solve threshold puzzles to permit them to access, or reaccess, selected portions of the narrative on the audio and/or visual playback device. The players gather sets of information fragments to solve a global meta-puzzle.

Abstract: An apparatus (10) of the type for applying an elastic ribbon (18) onto the surface of a moving web (12) in curved line path relative to the longitudinal centerline (14) of the web (12) includes a nip roll (16) for directly rolling the elastic ribbon (18) into engagement with the moving web (12) and an oscillating roll (20) adjacent to and spaced from the nip roll (16) for oscillatiang the elastic ribbon (18) in a direction transverse the centerline of the web (12) and applying the elastic ribbon (18) to the nip roll (16) in the curved line path. A guide roll (22) guides the elastic ribbon (18) to wrap around the oscillating roll (20) and tension the elastic ribbon sufficiently for tracking and holding the lateral position of the elastic ribbon (18) on the nip roll (16) to be applied to the moving web (12) in the curved line path.

Abstract: A disposable absorbent article, such as a diaper, having a liquid impervious backsheet, a urine pervious liner, and absorbent core intermediate the backsheet and liner is disclosed. The liner has a passageway to allow communication of solid waste materials to the core, thereby isolating such waste from the skin of the wearer. The liner is longitudinally contracted by elastic strands disposed longitudinally nonadjacent the passageway, improving the fit of the article to the wearer without sacrificing leakage protection and allowing various sections of the article to assume independent functions.

Abstract: A closed cell, rigid, polymer foam containing as filler at least about 2 percent by weight of carbon black, based on the weight of the polymer in the foam, the carbon black being uniformly dispersed throughout the foam so that there is present in the cell walls of the foam an amount of carbon black which reduces the aged k-factor of the foam to below the aged k-factor of the corresponding unfilled foam.

Abstract: An apparatus and method is disclosed for attaching a continuously moving elastic ribbon to a continuously moving web such that only selected discrete areas of a finished conformable garment fabricated from the web are elasticized. The web is moved into engagement with a continuously moving first conveyor means having a plurality of spaced apart gaps in its surface and the first conveyor means travels along an inclined guide means toward a second conveyor means traveling opposite to and in the same direction as the first conveyor means. The second conveyor means carries a plurality of spaced apart web tucking means which are moved by the second conveyor means into registry with the gaps in the first conveyor means. As each of the web tuck means move in registry with the gaps, the web tuck means are inserted into the gaps to form tucks in the web due to the movement of the first conveyor means toward the second conveyor means.

Abstract: A method and apparatus for elasticizing the leg areas of disposable diapers is disclosed. Portions of a continuously moving elastic ribbon are attached to a continuously moving web at spaced apart locations along the length of the web corresponding to the leg areas of a finished diapers. The web is moved over at least one arcuate surface and the portions of the ribbon that are not attached to the web are drawn through a slot in the surface so that the unattached ribbon portions separate from the web and travel a shorter path than the web. While the unattached portions of the ribbon are passing through the slot, they are clamped intermediate their ends by clamping means. While the unattached ribbon portions are held clamped, they are cut at their ends by cutting means.

Abstract: A flame detector device for use with boiler systems has been devised wherein a radiation sensitive means responds when energized by incident radiation of the selective frequency bandwidth to produce a signal indicative of the existence of a flame. A light pipe means includes a lens system for collecting incident radiation in a selected combustion zone of the flame and a flexible tube couples the radiation sensitive means and the lens system. A fiber optics bundle conveys the collected incident radiation from the lens system to the detector and is of an extruded high purity unclad quartz material thereof.

Abstract: An arrangement of modular elements comprising a balance beam having a narrow top rail and trapezoidal base with steep sides giving the illusion of shallowness adapted by connecting means to be used together with one or more cylindrical pedestals each having a well and a recessed disc seated in said well which serves to carry a message and acts as the target or destination of a child walking the rail along a roughened strip longitudinally extending the length thereof, the child sensing the strip by the sense of touch through the bottom of his feet.

Abstract: A solid state detector for use in detecting submillimeter and millimeter wave radiation. The solid state detector comprises a semiconductor superlattice of alternating thin epitaxial layers of GaAs and AlGaAs doped with impurities having the same conductivity type. Because of the transfer of charge carriers in order to obtain thermal equilibrium, the charge carriers in the higher energy doped layer transfer to the adjacent lower energy doped layer and form a predetermined number of either D.sup.- or A.sup.+ centers in this layer. This D.sup.- or A.sup.+ center formation is obtained without the use of an optical bias. The ionization energy for these D.sup.- or A.sup.+ centers is small enough that photons from millimeter or submillimeter wave radiation is sufficient to ionize these carriers and yield a measurable conductivity in the device.
