Abstract: Pigmented inks are disclosed comprising an aqueous medium, a pigment, a dispersant, and a humectant. Inks are disclosed where the humectant is a sulfonated polyethylene oxide which provides long decap times and fast drying of the printed image. Inks are further disclosed where the dispersant is an alkyl(sulfophenoxy)benzenesulfonic acid or its salt. Such dispersants reduce the agglomeration of pigment particles and reduce or eliminate the deposition of foreign substances on heater elements during the jetting process. A variety of pigments, dispersants, humectants, and aqueous media can be used. Combinations of a sulfonated polyethylene oxide humectant and an alkyl(sulfophenoxy)benzenesulfonic acid (salt) dispersant provide inks with good stability, few kogation problems, long decap times and relatively fast drying times.

The complexes are useful in systems for initiating the polymerization of acrylic monomer, which systems further include an amine reactive compound. Polymerizable acrylic monomer compositions useful as adhesives can be prepared.

Abstract: A dental impression tray has wall portions defining at least one channel for receiving a quantity of photocurable dental impression material. At least one of the wall portions is located next to the chamber and is made of a material that transmits electromagnetic actinic radiation. The tray also includes a chamber for receiving a chemiluminescent composition. Light emitted from the chemiluminescent composition induces the curing of the impression material in a uniform manner along the length of the channel.

Abstract: A personal, biometric authentication system is disclosed. The system can be used for controlling access to equipment or physical facilities. The system employs the combination of a unique, inherently specific biometric parameter recognized and compared with stored data and at least one non-specific biometric parameter of a physiological characteristic recognized and compared with physiological norms. Positive comparison results in authentication of an individual that is not incapacitated, dismembered, or deceased.

Abstract: The present invention provides an article including 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: A high speed connector allows the conductors of a cable to be connected directly to the circuit traces of a printed circuit board by providing a plug having an end where the conductors terminate and a housing for the plug which cooperatively urges the conductors toward the circuit board.

Abstract: An article is held in a complementally-shaped receptacle of a resilient holder while a process operation is carried out on a surface of the article. After the process operation has been completed, the holder is bent in order to facilitate release of the article from the receptacle. The method is particularly useful for performing a process operation such as sandblasting, etching or otherwise treating an inner surface of a hollow article such as an orthodontic band or dental crown while a portion of the holder masks and thus protects its outer surface.

Abstract: A cable end seal for a multiple-conductor oil filled cable includes an inner sealing boot adjacent the cable and filled with an oil restraint material for the temporary restraint of cable oil and an outer boot and cylindrical mold filled with hardenable material for the permanent containment of the cable oil. The inner boot and oil restraint material prevents contact between the oil and the material at least until the material has hardened.

Abstract: A system and method for spraying single or multiple component fluid systems onto a surface. The spray applicator utilizes a venturi effect to independently draw fluids from separate containers, atomize the fluids and spray the fluids in a desired pattern onto a surface. The atomized streams generally overlap so that the fluids mix prior to contacting the target surface. In one embodiment, the fluids are retained in flexible containers separately connected to a spray applicator by flexible tubes. The flexible containers include a fitting for receiving a fluid draw tube and a releasable closure for expelling excess pressure within the container.
