Abstract: Display elements of computer screens and other information displays are printed using conservative printing techniques. Contemplated electronic components that can be conservatively printed at the display element level include switches, transistors, capacitors, memory elements, and actuators. Contemplated light path components that can be conservatively printed at the display element level include light pipes or other optical wave guides, mirrors, light emitting diodes, liquid crystals, and actuators. The conservatively printed components may advantageously be produced by a process that includes depositing a precursor onto the substrate in a desired pattern, depositing an appropriate ligand onto the substrate, and applying sufficient energy to transfer electrons from the ligand to the precursor, thereby decomposing the precursor to form a precipitate. In an especially preferred class of embodiments, light emission at individual display elements is controlled by a conservatively printed moving actuator.

Abstract: Apparatus and methods are provided in which software resident on a user's computer interfaces with software and/or supplemental information resident on a provider's computer via a transmission line to manipulate a batch of data from a plurality of records extracted from a user's mailing list. In a preferred embodiment, the user resident software directs the user's computer to extract data from multiple records within the user's mailing list. The user resident software then batches the extracted information, and transmits it across a transmission line to the provider's computer.

The provider's computer then either transmits updated, sorted or otherwise modified data back to the user's computer for reintegration into the user's mailing list, print labels, reports or produce other output at the provider's location, or performs some other function with the data.

Abstract: Methods and compositions are provided which decrease the risk and spillage associated with discharging coke from a coking vessel. The risk to workers is decreased by eliminating the need for workers to be near the coking vessel while the head is being removed. The spillage is decreased by modifying the effective diameter of the coke chute inlet in a manner which allows it to catch any materials discharged from the coking vessel both during and after the opening of the bottom head. The process can enhance drum draining and further eliminate the need for process piping to facilitate the draining of water from the coking vessel.

Abstract: An oil drain valve consisting of a drain fitting and a removable actuator. The drain fitting is substantially the size and shape of a standard oil, is axially hollowed, and is perforated in the walls thereof to form a passageway to drain oil from the oil pan. The passageway contains a spring-loaded ball valve. The drain fitting is internally threaded on its bolt end to accommodate the external threads of the actuator. A mechanically advantaged lever is positioned within the actuator such that tightening and loosening of the actuator within the drain fitting causes the opening and shutting of the ball valve. The actuator may be fitted to a hose and optional pump for disposal of the oil. A protective cap is mounted within the head end of the drain fitting when the fitting is not in use.
