Abstract: The present invention provides an article comprising a curable resin and a filler associated with the resin. The incorporation of fillers into the casting materials of the present invention adds substantially to the strength of the cured casting material as well as to the handling properties of the uncured casting tape or bandage. The incorporation of fillers into the casting materials of the present invention also imparts air and vapor porosity to the cured casting materials. If desired articles of the present invention may also incorporate fibers (either individually, bundled, or in the form of a light-weight scrim) to provide increased cohesiveness to the uncured article. Extremely moldable casting tapes are also provided which comprise a highly-filled composite material coated on a light-weight scrim. The casting tapes of this embodiment handle like traditional plaster of Paris casts yet cure to a weight-bearing cast in less than one hour.

Abstract: Sheets to be coated with water-based coating material, for example a primer and a low adhesion backsize, are supplied from a feeder (1), in end-to-end overlapping relationship, to a dual coater (3) in which the sheets are coated individually on both sides. A sheet inserter (2) is provided, upstream of the dual coater, to insert sheets from a second supply into the sheets from the feeder (1). The dual coated sheets are dried as individual sheets or as a pseudo-web of overlapped sheets. The sheets are then overlapped, unless previously overlapped, and the direction of overlap changed, if necessary, to provide the trailing edge of each sheet on top of the leading edge of each succeeding sheet. The overlapped sheets are conveyed through an adhesive transfer station (7) where stripes (236) of at least partially dried adhesive are coated onto the dual coated sheets from a transfer belt (71).

Abstract: A valve diaphragm 14 is connected to a valve base 11 by locating the diaphragm on upstanding posts 18 which are formed integrally with the valve base, and then cutting and simultaneously deforming the posts to secure the diaphragm in position. The cutting/deforming operation involves: forming two longitudinal cuts in each post, defining a central section 21 and two outer deformable sections 22, 23; and bending the deformable sections outwards, away from the central section.

The compatibilizing layer provides an intermediate layer between the retroreflective layer and the flexible fabric material creating suitable bond strength between dissimilar polymers.

Abstract: An abrasive article back up pad having a resilient, open cell polyurethane foam formed as the reaction product of a polyether polyol and an aromatic polyisocyanate, such as an aromatic polyisocyanate including methylene diphenyl diisocyanate ("MDI"), and this foam is attached to the backside of an abrasive article.

Abstract: A system for substantially maintaining color density in liquid toners for electrographic printers is disclosed. The system includes means for substantially continuously supplying toner concentrate to a printer and means for substantially continuously withdrawing liquid toner from a printer into a waste flowstream. A method to achieve substantially consistent color density of liquid toner in an electrographic printing system is also disclosed.

Abstract: The present invention provides circuit articles which are damped and stiffened relative to resonant vibrations and shock. At least one vibration damping and stiffening member comprising a constraining member comprising a base having at least one projection and a layer(s) of vibration damping material is attached to the circuit article. These member(s) act to stiffen the circuit article and also add significant damping to the circuit article while potentially taking up only a relatively small circuit article surface area.

Abstract: A fluorescent ionophoric compound is disclosed that includes a complexing moiety, such as a cryptand or crown-ether portion, and a fluorescing moiety such as a coumarin portion. The coumarin portion may be substituted at the 3-position with an electron withdrawing or polarizable group such as a substituted aromatic group or a substituted heterocyclic group having a heteroatom in at least one of its alpha positions. The compound, which exhibits good photostability, can be incorporated into cation-sensing composite structures by means of convenient points of covalent attachment.

Abstract: Encapsulated electroluminescent phosphor particles and a method of making same. Each phosphor particle is encapsulated by a substantially transparent aluminum oxide-based multiple oxide coating. The encapsulated phosphors exhibit high initial luminescent brightness and high resistance to humidity-accelerated decay of luminescent brightness. The aluminum oxide-based coating provides reduced sensitivity to chemical degradation caused by exposure to condensed moisture or otherwise liquid water. The coating comprises the aluminum oxide and at least one other metal oxide.

Abstract: A spray assembly for mixing catalyst with a high viscosity material and applying thin coatings of that material to a substrate that is particularly useful for applying body putty to a surface. The spray assembly has first and second through air passageways between an inlet end portion and different portions of an outlet end. The through air passageways each have a straight central axis adjacent the outlet end, the extensions of which axes outside the spray nozzle intersect a short distance from the outlet end of the spray nozzle. A large suction tube for the larger first air passageway has an upper end positioned within a cylindrical portion of the first air passageway. Air streams propelled through the passageways draw high viscosity material through the larger suction tube and catalyst through a smaller suction tube into those air streams. Intersection of those air streams outside of the nozzle mixes the catalyst material with the high viscosity material.

The corrugated nonwoven web has a solidity of 0.1 or less and contains microfiber and crimped staple fibers that have a percent crimp of at least 15 percent.

Abstract: A method for attenuating sound waves passing from a source area to a receiving area comprises the steps of providing a nonwoven acoustical insulation web comprising thermoplastic fibers, the web having an average effective fiber diameter of less than about 15 microns, a density of less than about 50 kg/m.sup.3, and an air pressure drop across the web of at least about 1 Mm water at a flow rate of about 32 liters/min.; and positioning the web between the source area and the receiving area such that a major face of the web intercepts and thereby attenuates sound waves passing from the source area to the receiving area. Also, a laminate adapted to be applied to the inner panel of a vehicle door comprises the web and a second layer, such as a scrim, nonwoven fabric, film, or foil, laminated thereto. The laminate can be applied to the inner panel of a vehicle door so that the second layer provides water barrier protection and the web provides acoustical insulation.
