Abstract: The present invention relates to radically curable compositions for curing on a surface comprising a radically curable component, and an initiator component capable of initiating cure of the radically curable component. The initiator comprises at least one metal salt and a free radical generating component. The metal salt of the composition is chosen so that it is reduced at the surface, where the standard reduction potential of the metal salt is greater than the standard reduction potential of the surface, and where when the composition is placed in contact with the surface, the metal salt is reduced at the surface, and interacts with the free radical generating component, thereby initiating cure of the radically curable component of the composition. No catalytic component is required in the composition for efficient curing.

Abstract: The present invention relates to cationically curable compositions for curing on a surface comprising a cationically curable component, and an initiator component capable of initiating cure of the cationically curable component. The initiator comprises at least one metal salt, which is chosen so that it is reduced at the surface, and where the standard reduction potential of the initiator component is greater than the standard reduction potential of the surface, and where when the composition is placed in contact with the surface, the metal salt of the initiator component of the composition is reduced at the surface, thereby initiating cure of the cationically curable component of the composition. No catalytic component is required in the composition for efficient cure.

Abstract: Methods for digitizing complex surfaces of dental objects such as impressions of dental surfaces and shapes. While an impression mold is being scanned by translation along a known trajectory, typically in a plane, the line of sight of a distance probe is directed toward successive positions on the surface of the impression mold, such as by a periodic series of reflecting surfaces characterized by normal vectors at distinct non-orthogonal angles with respect to their axis of symmetry. One or more reference objects are scanned using the same translation and mirror positioning systems. Gathered coordinate data are processed to apply angular corrections and combined to form a single distortion-corrected image of the impression mold. An apparatus and methods are provided for measuring both sides of a dental object separately, and then registering the two sides relative to each other in a digital representation of the object.

Abstract: A drum assembly for use with a coupling arrangement includes an outer member and an inner member that is mountable on the outer member. The outer member includes first and second annular portions and an intermediate portion extending between the annular portions. The first annular portion has a first mating surface that defines a first opening having a first diameter, the second annular portion defines a second opening having a second diameter that is smaller than the first diameter, and the intermediate portion defines a shoulder. The inner member includes a generally radially extending portion having a generally axially facing surface and a second mating surface that is engageable with the first mating surface to interlock the inner and outer members together. When the inner member is mounted on the outer member, the radially extending portion extends into the first opening, and the generally axially facing surface engages the shoulder.

Abstract: A drum assembly for use with a coupling arrangement includes an outer member and an inner member that is mountable on the outer member. The outer member includes first and second annular portions connected together. The first annular portion has a first mating surface that defines a first opening having a first diameter, and the second annular portion defining a second opening having a second diameter that is smaller than the first diameter. The inner member includes a generally radially extending portion and a flange portion extending generally axially from the radially extending portion. The radially extending portion includes a second mating surface that is engageable with the first mating surface to interlock the inner and outer members together. When the inner member is mounted on the outer member, the radially extending portion extends into the first opening, and the flange portion extends into the second opening.

Abstract: A method for provisioning audiovisual works to a client includes maintaining categorization information specifying, for each of multiple audiovisual works, one or more of multiple categories. One or more of the categories are associated with each of multiple delivery slots in response to input from a client. For each of the delivery slots, a first audiovisual work from one of the categories associated with the respective delivery slot is provisioned for delivery to a location associated with the client.

Abstract: A coupling assembly includes a housing disposed about an axis and having a retainer. The assembly further includes a coupling pack disposed about the axis, and an actuator lever having an end engaged with the retainer of the housing such that the actuator lever is pivotable with respect to the housing for applying an axial force on the coupling pack. Moreover, the retainer inhibits axial movement of the end of the actuator lever.

Abstract: A system for cleaning totes is disclosed in which each tote has a fill opening at its top and a dispensing valve, both of which are open to an interior chamber of the tote. The system includes a conveyor line having a receiving end and a discharge end and which is adapted to transport the totes from the receiving and to the discharge end. At a first station along the conveyor, the tote is initially drained of any remaining fluid within its interior and the tote is then moved to a second station. At the second station, a wash solution is cycled through the tote in order to clean the interior of the tote. The wash solution is recycled and appropriate fillers are used to remove the impurities from the wash solution. The tote then progressively moves through three rinse stations along the conveyor line in which each rinse station includes a lid attachable to the fill opening of the tote and which progressively rinses the interior of the tote.

Abstract: This invention concerns itself with improvements to cubical quad antennas. The chief disadvantage to cubical quad antennas is their relative lack of strength and vulnerability to high winds and icing conditions. The present invention provides for a spreader reinforced crossarm system that adds appreciably to the strength of these antennas. There is also the added advantage that additional elements can be added and supported by the aforementioned guy line support system, thus alleviating the necessity for a crossarm assembly for each element. The one additional advantage of the invention is that elements can be supported by the ends of the spreaders themselves, thus affording a greater distance between elements than would be possible with just the boom and no spreaders with the effect of increasing the gain of the antenna array.
