Title: Method of manufacturing toric single vision, spherical or aspheric bifocal, multifocal or progressive contact lenses
Inventor: BLUM RONALD D
IPC: B29D11/00
Filed: 1993-11-23
Granted: 1999-05-25
Abstract: A method for making a finished aspheric single vision, spherical or aspheric bifocal, multifocal or progressive addition contact lens includes the step of fitting a patient requiring a near correction with a single vision spherical or aspheric contact lens for optimal distance vision and comfortable fit. The patient is then over-refracted to determine the required near correction to be embodied in the contact lens. A portion of the optic corresponding to the center location of the pupil is marked on the convex side of the optic to form an optical preform. The optical preform is removed from the eye of the patient and the concave side of the optical preform is marked at a position corresponding to the mark on the convex side that denotes the center of the pupil. The mark disposed on the convex side of the optical preform is removed. A specified volume of polymerizable resin is placed in a mold embodying the required correction, which includes an add power zone so that the resin fill s the intervening space between the mold and the optical preform. The add power zone is aligned on the optical preform to a predetermined position with respect to the mark on the optical preform designating the center of the pupil. The resin is then polymerized, the optical preform is demolded to obtain the finished contact lens having the required correction.

Title: Fluid extraction of metals and/or metalloids
Inventor: WAI CHIEN M
IPC: C01F17/276
Filed: 1994-06-09
Granted: 2001-06-05
Abstract: A method of extracting metalloid and metal species from a solid or liquid material by exposing the material to a supercritical fluid sol-vent containing a chelating agent is described. The chelating agent forms chelates that are solu-ble in the supercritical fluid to allow removal of the species from the material. In preferred em-bodiments, the extraction solvent is supercritical carbon dioxide and the chelating agent is a fluo-rinated .beta.-diketone. In especially preferred em-bodiments the extraction solvent is supercritical carbon dioxide, and the chelating agent com-prises a fluorinated .beta.-diketone and a trialkyl phosphate, or a fluorinated .beta.-diketone and a tri-alkylphosphine oxide. Although a trialkyl phos-phate can extract lanthanides and actinides from acidic solutions, a binary mixture comprising a fluorinated .beta.-diketone and a trialkyl phosphate or a trialkylphosphine oxide tends to enhance the extraction efficiencies for actinides and lan-thanides. The method provides an environmen-tally benign process for removing contaminants from industrial waste without using acids or bi-ologically harmful solvents. The method is par-ticularly useful for extracting actinides and lan-tanides from acidic solutions. The chelate and supercritical fluid can be regenerated, and the contaminant species recovered, to provide an economic, efficient process.

Title: Method and apparatus for providing print job buffering for a printer on a fast data path
Inventor: BENDER MICHAEL DONALD
IPC: G06F3/12
Filed: 1997-02-12
Granted: 2003-04-29
Abstract: An improved printer is provided that improves the response time before jobs are printer by providing a "fast data path" for certain print jobs while also storing on a hard disk all incoming print job data. This "fast data path" is especially useful in situations where the incoming print job lacks an "end of file" code, which couldotherwise hold up the processing of either this print job or later print jobs. Once the printer becomes relatively busy, and begins to accumulate a "queue" of print jobs waiting to be processed and printed, the printer will automatically store all of the print job data on the non-volatile memory (e.g., a hard disk) before that same data is sent to the processing circuitry. Since it is important to utilize the printer's capabilities efficiently, the printer can allow a "small" print job to be processed and printed after being received from one input port of the printer, while a much larger print job is still being accumulated from a second input port, even though the larger job began to be received first. Since all print job data received by the printer of the present invention is stored in a non-volatile memory, the capability exists for recovering such print jobs after the occurrence of a power failure. Upon power restoration, a "Header File" that contains status information about stored print jobs will be inspected, and if a print job was never completely printed, the printer will now begin printing the entire job. In this manner, the printer can guarantee that the entire job will be printed in one intact grouping of sheets of paper.

Title: Bandpass woofer and method
Inventor: POLK MATTHEW S JR
IPC: H04R1/28
Filed: 1995-08-09
Granted: 1999-09-21
Abstract: A single-vented bandpass woofer loudspeaker system design and method for enabling operation in smaller enclosure volumes with only moderate loss of efficiency. The bandpass system has an enclosure (11) with a partition (14) dividing it into a first sealed chamber (12) and a second chamber (13) having a passive radiating port (18) communicating with air outside the enclosure. A driver (16, 17) is mounted in the partition. Novel, empirically determined tuning ratios which depend upon system variables are defined. By adjusting the system variables to keep the tuning ratios within empirically determined values, a good relationship between flat response, bandwith and efficiency is achieved. Unexpectedly, using a higher than normal moving mass of the driver leads to an acceptable system with a very small enclosure volume.
