Title: High solids lime as a caustic replacement
Inventor: HUEGE FRED R
IPC: C02F1/52
Filed: 1996-08-23
Granted: 2008-08-05
Abstract: A composition for a pumpable lime slurry which is adapted for use as a replacement for caustic solutions is formed by combining a dispersing agent in lime and water to form an aqueous slurry. The amount of lime used is between 35 to 55 % by weight of the slurry.  The dispersing agent, which is an anionic polyelectrolyte, such as polyacrylic, polycarboxylic acids and alkali metal salts thereof, is added in an amount between 0.1 to 3 % by weight of the lime. To this is added an alkali metal hydroxide of 0.1 to 1.5 % by weight of lime. The order of addition of the alkali metal hydroxide is important. The later addition of the alkali metal hydroxide results in a decreased viscosity so that a lower amount of dispersing agent is required.

Abstract: A tube heat exchanger intended to be used for the production of carbon black, comprises a cylindrical chamber (16) which is enclosed by a cylindrically shaped outer shell wall (14') and two end walls (17, 18), and a plurality of tubes (13') which extend through the entire cylindrically shaped chamber (16), from one end wall to the other. To the heat exchanger are provided an inlet (1') and an outlet (25) for gas intended to flow on the outside of the tubes (13'). Moreover, the heat exchanger comprises a further shell wall (23), which is cylindrical and placed inside and concentrically with the outer shell wall (14'), so that a cylindrically shaped gap space (29), which is open at both ends, is formed between the two shell walls. The gas entering through the inlet (1') passes this gap space (29) before it comes into contact with the tubes (13'). The advantage of this is that the outer shell wall is cooled and that the amount of carbon precipitations within the tubes diminishes.

Abstract: An automatic chemistry analyzer is provided having a high throughput and a high reliability. The analyzer uses nephelometric and turbimetric analyzers (68) to analyze a wide variety of parameters within liquid samples typically generated in, for example, a large medical testing laboratory. The machine employs a unique probe (84) and stirring rod (86) assembly (80) mounted at a slight angle (.alpha.) with one another using rack and pinion assemblies (106) so that the lower end of the probe (84) and the lower end of the stirring rod (86) are in very close proximity to one another. This feature allows the machine to be used in unusually small reaction cuvettes (54). The analysis machine also includes an onboard control sample (78) so that the machine can be programmed to periodically calibrate its analyzing equipment during the course of normal operation. The machine also includes a sample station carousel (24) having retainer clips (39) for retaining a sample container rack (30) which is constructed to retain a bar-coded card (37) containing information regarding reagents used in the machine. A bar code reader (47) located proximate to the sample carousel reads the bar-coded reagent information into the controller.      Also provided are a cuvette wash station (130) and a waste trap assembly (138).

Title: Automatic semiconductor wafer sorter/prober with extended optical inspection
Inventor: CHAPMAN ROBERT L
IPC: G01R31/01
Filed: 1997-07-07
Granted: 2004-01-06
Abstract: A method and apparatus (11) for visually inspecting and sorting semiconductor wafers (23a, 23b, 23c) and the individual microcircuits or chips thereon. The preferred embodiment employs a scanner (37) to obtain a virtual reality image of the wafer (23) and all chips are identified and sorted by applying high-speed image processing routines. The resulting wafer map provides unique image controlled chip coordinates making the chips identifiable even after the chips are diced apart. The wafer may contain different kinds of chips in irregular patterns. A gross-defect, visual inspection (17) sorts out defective chips based on image completeness maximizing the yield and throuthput. All inspections and identification are performed on the virtual wafer (23) or chip images scanned into a computer memory with full physical wafer correlation but without having to manipulate the wafer. The inspection time is, therefore, largely free due to overlapping it by regular transport operations.

Title: Method and apparatus for coupon management and redemption
Inventor: FAJKOWSKI PETER W
IPC: G06Q20/38
Filed: 1997-10-27
Granted: 2007-04-10
Abstract: The present invention provides a system for the electronic management and redemption of coupons. The system includes an integrated coupon card (1) comprising a memory means (22, 23), a scanner, and a communication port. The card is capable of scanning coupon bar codes and receiving data from a periphery device (27).

The system further includes one or more periphery devices (100), a communication port for communicating with coupon card and with a cash register. The periphery devices receive purchase data from a cash register and compare said data to coupon bar codes received from said card in order to determine which coupons are redeemable. The system also includes a server computer (200). The server will collect redeemed coupon information from the periphery devices and provide the periphery devices with redemption information. A clearing house will collect coupon redemption information from the system to create redemption reports.

Abstract: A system and method for creating and processing a unified stream of data that includes both temporal and non-temporal data, preferably in a compressed format. A scheduler (602) takes temporal data (e.g. sound data) and non-temporal data (e.g. image data) and interleaves them together to form a unified data stream (610). A processor is included that decompresses compressed image data and produces an output image from both decompressed image data and any uncompressed image data. The processor also plays the temporal data (604) while concurrently decompressing the compressed temporal data. Temporal data (604) may be in any format, including voice data and MIDI  files, as well as image data, including videos and still images. A computer slide show may be formed by scheduling and playing video and sound data (including MIDI and voice), in which the video and sound data are interleaved into a unified data stream (610).
