Abstract:
A computer-based system and method calculates and facilitates revenue accrual, for making larger, less frequent payments of estimated taxes or other obligations. Payer preferences are applied to satisfy variable payment intervals, amounts, and available resources. The obligation, required payments, and set-aside schedules are recalculated as needed, under payer and/or system control. Excess accruals are minimized; set-aside schedules are configurable. The system may be self-contained, handheld, or accessed remotely. Automatic datalinks move information and command fund transfers from the payer's bank, to accrue funds and make payments to other accounts. A service host may support a plurality of payers to make set-asides and payments at various levels as needed, on an individual or batch basis, including individual taxpayer enrollment for batch file tax payments by service providers. Some embodiments can be embedded to enhance the capabilities of other systems.
Abstract:
A light source incorporates phosphor-based white light emitting diodes (LEDs). The LEDs may be raised off the floor of the optical cavity to permit light to be emitted from the base of the LED. Additionally, a reflective protrusion may be placed beneath the raised LED to aid in redirecting light forward. The LEDs may be skewed in relation to adjacent LEDs to reduce interference. Non-white LEDs may be incorporated into the light source to permit for selective color tuning. Fluorescent lamps may also be implemented in combination with the LEDs to form a hybrid light source. The light source may be used as a backlight for a liquid crystal display assembly.
Abstract:
Provided are a method, system, and program for archiving files. A hierarchical file system having directories is provided. An archival retention policy is associated with at least one of the directories in the hierarchical file system, wherein the retention policy applies to files included in the associated directory, and wherein the retention policy specifies a retention time indicating a time period during which a file is subject to the retention policy.
Abstract:
A sulfate process for producing titania from a titaniferous material is disclosed. The process includes leaching the titaniferous material and producing a leach liquor, separating titanyl sulfate from leach liquor, hydrolysis of the extracted titanyl sulfate, and thereafter calcining the solid phase produced in the hydrolysis step. The process is characterised by multiple stage leaching of the titaniferous material.
Abstract:
A sulfate process for producing titania from a titaniferous material is disclosed. The process includes leaching the titaniferous material and producing a leach liquor, precipitating iron sulfate from the leach liquor, solvent extraction of titanyl sulfate from leach liquor, hydrolysis of the extracted titanyl sulfate, and thereafter calcining the solid phase produced in the hydrolysis step. The process is characterised by using at least part of the raffinate from the solvent extraction step as at least part of the leach solution in the initial leach step.
Abstract:
A sulfate process for producing titania from a titaniferous material is disclosed. The process includes leaching the titaniferous material and producing a leach liquor, separating titanyl sulfate from leach liquor, hydrolysis of the extracted titanyl sulfate, and thereafter calcining the solid phase produced in the hydrolysis step. The process is characterised by controlling the hydrolysis step and forming a selected particle size distribution of hydrated titanium oxides from titanyl sulfate.
Abstract:
A lamp includes an enclosure with partitions defining a channel having channel segments and/or providing multiple paths for an electrical arc to travel. The channel segments can be implemented by adding additional electrodes in the channel formed by the partitions, by forming a channel where the arc may travel in multiple directions, or by a combination of these methods. The channel segments and multiple directions of arc travel tend to reduce the voltage required to start the lamp.
Abstract:
Provided are a method, system, and program for receiving a request to remove a record. A determination is made as to whether a state associated with the record includes at least one hold state and whether the state associated with the record includes at least a retention period that has not expired. The request to remove the record is denied in response to determining that the state associated with the record includes at least one of at least one hold state and one retention period that has not expired.
Abstract:
A process for upgrading brown coal is disclosed, including providing at least two converging surfaces defining a nip, wherein at least one of the surfaces is rollable in a direction toward the nip; feeding the brown coal to the nip where, by the rolling action of the rollable surface, the brown coal is subjected to shearing stresses, causing attritioning of the microporous structure of the brown coal and the release of water contained in the micropores; and continuing the shearing attritioning until the brown coal forms into a plastic mass. Processes for the production of char are also disclosed utilizing as feed material pellets formed from the upgraded brown coal produced by the above process, as well as a process for recovering metal from a metal containing material.
