Abstract: There is disclosed a water-reducible, chrome-free coating composition for providing corrosion protection to a substrate, such as a metal substrate. The deposited coating film is corrosion-resistant and, for coated articles which are threaded, e.g., steel fasteners, the coating provides a non-thread-filling coating. The coating composition contains particulate metal, such as particulate zinc or aluminum. Although substituents can be separately packaged, the composition is virtually always a one-package coating composition. The composition is water-based, while also containing low-boiling organic liquid. The composition also contains water-reducible organofunctional silane, particularly an epoxy functional silane, as a binding agent. The composition has highly desirable, extended shelf life. The composition can be easily applied in usual manner, such as dip-drain or dip-spin technique, and readily cures at elevated temperature.

Title: High fiber count, compact, loose tube optical fiber cable employing ribbon units and flexible buffer tubes
Inventor: CHAMBERLAIN RICHARD
IPC: G02B6/44
Filed: 2000-10-20
Granted: 2008-10-14
Abstract: An optical fiber cable has a longitudinally extending central strength member and at least one substantially fluid impervious, flexible plastic buffer tube S-Z wound around said central member in an alternating hand helix, said alternating hand helix having a lay length of from about 400 mm to about 600 mm. Superimposed ribbon units in stack are loosely received in the tube, each ribbon unit comprising optical fibers held together in side-to-side relation in a non--conductive material. The stack of superimposed ribbon units has an axial length from about 0.1% greater than to about 0.2% less than the axial length of the tube and has a width transverse to the stack axis and a thickness transverse to the stack width. The ribbon units are helically twisted around the axis of the stack with a pitch of from about 250 mm to about 1000 mm in the tube. The ratio of the pitch of the superimposed ribbon units to the lay length of the tube is from about 0.5 to about 1.2. There is a clearance C between the superimposed ribbon units and the inner diameter of the tube wall between about 1 mm and about 2 mm with the relation; C = (T I2 - W R2)1/2 -H R where T I is the inner diameter of said tube, W R is the width of said stack and H R is a thickness of said stack. A sheath of plastic material encircles the central strength member and the tube wound around the central member. The ratio of the ribbon pitch to the tube lay length, the clearance and the axial length of the stack are selected to provide optical signal attenuation in the optical fibers of less than 0.30 average dB/km at a 1550 nm wavelength.

Title: Apparatus and method for preparative supercritical fluid chromatography
Inventor: NICKERSON MARK
IPC: B01J3/00
Filed: 2001-05-14
Granted: 2005-08-09
Abstract: A fractionated sample collection process and device having at least one pressurized chamber used to gather and store liquid samples generated from a flow stream containing a mixture of highly compressed gas, compressible liquid, or supercritical fluid and a relatively incompressible liquid. A bank of multiple collection chambers is secured together in a frame to form a cassette unit. Each collection chamber may house a replaceable liner such as a test tube vial, to hold a fractionated liquid phase sample. After filling with sample, a collection chamber is returned to a clean state and ready for refilling with a new sample by manually or automatically replacing the liner. The separation and collection process partitions the liquid phase, containing modifier and dissolved sample components from the gaseous phase components upstream of the collection chamber so that liquid phase has controlled discharge into the collection chamber. Movement and replacement of collection chamber liners to capture liquid fractions can be manually or robotically controlled. Automatic replacement of liners increases the speed of production as well as quality control by preventing drips and spills and possible carryover contamination of samples. The system provides extremely efficient and controllable gas and liquid phase separation, thereby effecting up to 98% injection recovery. The collection process is environmentally friendly and economical because it eliminates additional uses of solvents to collect, trap, or recover fractions. In addition, the process eliminates any additional cleaning solvents associated with mechanical phase-separation devices. The invention promotes high speed, high volume, and high quality fractionated SFC sample production.

Such Fc receptors can easily be obtained by expressing respective nucleic acids in prokaryotic host cells and renaturation of the obtained inclusion bodies, which procedure leads to a very homogenous and pure product. The products can be used for diagnostic as well as pharmaceutical applications and also for the generation of crystal structure data. Such crystal structure data can be used for the modelling of artificial molecules.  A further embodiment comprises coupling the Fc receptors according to the invention to solid materials like chromatography materials that can be used to separate and/or enrich antibodies.

Title: Acoustic correction apparatus
Inventor: YUEN THOMAS C K
IPC: H04S1/00
Filed: 2000-10-04
Granted: 2010-08-10
Abstract: An acoustic correction apparatus (120) processes a pair of left and right input signals (126, 128) to compensate for spatial distortion as a function of frequency when said input signals (126, 128) are reproduced through loudspeakers (246, 247) in a sound system. The sound-energy of the left and right input signals (126, 128) is separated and corrected in a first low-frequency range and a second high-frequency range. The resultant signals are recombined to create image-corrected audio signals (130, 132) having a desired sound-pressure response when reproduced by the loudspeakers (246, 247) in the sound system. The desired sound-pressure response creates an apparent sound image location with respect to a listener (250). The image-corrected signals (130, 132) can also be spatially-enhanced to broaden the apparent sound image and improve the low frequency characteristics of the sound when played on small loudspeakers.

The first segment size represents a minimum segment size that can be transmitted. The second segment size represents a maximum segment size that can be transmitted. A segment is created and transmitted whenever a quantity of time-sensitive information available for transmission allows a segment to be constructed having a segment size between the minimum segment size and the maximum segment size.  A segment of any size up to the maximum segment size is also created and transmitted whenever any time-sensitive information is available for transmission and an acknowledgement message is received by the transmitter.

Abstract: The present invention provides an adjustable frame member (44) for a chair seat frame (66) and a lockable alignment tool (300) which is implemented between the chair seat frame (66) and an attachable seat back (68). Initially, the chair seat frame (66) is pre-assembled such that the adjustable frame member (44) is in a non-rigid state, therefore allowing for side to side skewing motion of the chair seat frame (66). The lockable alignment tool (300) is mounted onto the seat back (68), in its unlocked position. Once the lockable alignment tool (300) is mounted to the seat back (68), it is locked such that its length is fixed. The lockable alignment tool (300) is then removed from the seat back (68) and mounted onto the seat frame (14). As the lockable alignment tool (300) is mounted onto the seat frame (14), skewing motion of the seat frame (14) is caused as the seat frame (14) aligns with the lockable alignment tool (300). Once the lockable alignment tool (300) has been fully mounted to the chair frame (14), screws are used to lock the adjustable frame member (44). As such, the adjustable frame member (44) becomes a rigid structure. The lockable alignment tool (300) is then removed and overall assembly may be completed with proper alignment between the chair seat frame (14) and back (68) ensured.
