摘要:
Low viscosity, radiation curable fluid formulations that can be used advantageously as radiation curable, inks. The formulations are easily prepared for use in ink jet systems. The viscosity of the compositions is low enough so that conventional solvent is not required in order to satisfy the requisite low ink jet viscosity specifications. After curing, the compositions form durable, weatherable, abrasion resistant, printed images on a wide variety of porous and nonporous substrates. The formulations are very suitable for outdoor printing applications, especially for printing outdoor graphics onto a variety of surfaces, including vinyl or other polymer films commonly used for signage, retroreflective signage or other retroreflective items.

An adhesive composition includes a polymer adhesive material and a thickener. The adhesive composition has a stringing length of 9 cm or less and a phase lag of 45 degrees or less or a sag distance of 5 mm or less. The adhesive can be formed by combining a vinyl acetate polymer, an alkali swellable thickener, an alkali material, and water.

摘要:
In a disk storage device dedicated servo system, a reference track is written in the outer guardband of the servo surface and each of the data surfaces. Supplemental position error signal (PES) values are obtained from the difference of servo and data surface samples at a plurality of locations around the disk and stored for access during read/write operations. The supplemental PES values are combined with the dedicated surface PES values to yield a composite PES that more accurately follows the data track centerline of the disk surface being addressed. The supplemental PES values are also periodically updated. To provide a more accurate correction of the composite PES, two consecutive supplemental values are used and an interpolation is calculated to provide a continuously changing supplemental PES value for modification of each sector actuator drive pulse between the two current supplemental PES values. Provision is also made in the apparatus to make the correction technique tolerant of tangential skew that may make tracks unreadable because of early or late timing through the provision of sequences of alternative early and later sample sector sequences.

A slide garment for use in athletic activities and particularly for use by baseball players in which an apron or a separate material flap is secured to the jersey or shirt of the uniform in an area such that the upper edge of the apron will extend above the belt line or waistband of the pants of the uniform when the jersey is tucked within the pants and wherein the apron extends downwardly over the belt or waistband of the uniform and includes fastening elements for securing the lower portion of the apron to the upper portion of the pants to thereby prevent dirt and debris from entering between the pants and the jersey. In one embodiment, a simulated belt or waistband may be provided across the front surface of the apron.

A method is disclosed. The method comprises combining at least a polymer adhesive material, a thickener, and water to form adhesive compositions having a pH of 4 to 10, and identifying the adhesive compositions having a stringing length of 9 cm or less and one or more of the following properties: a set time of 180 seconds or less, a phase lag of 45 degrees or less, a viscosity of 3,000 to 50,000 cP, a complex shear modulus of 50 to 1000 Pa, and a sag distance of 10 mm or less.

A system and method for adaptively selecting content items to be displayed to users visiting a web portal. A system is disclosed that includes a content selection system for selecting a content item from a set of content items to display to a user based on a profile of the user and a set of business value scores associated with the set of content items; a data collection system for collecting performance metrics for users presented with the content items; an initialization system for generating an initial set of business value scores; and a business value generator for adaptively modifying the set of business value scores over time based on the performance metrics.
摘要:
Inkjet printing apparatus for use with radiation curable ink includes a sensor for sensing the amount of radiation emitted by a source of radiation. A controller is connected to the sensor and is operable to vary the amount of radiation emitted by the radiation source in accordance with a signal received from the sensor. A drive mechanism moves the source of radiation to a location laterally offset from the substrate where the sensor is positioned.
