Granted: 1993-03-23
Abstract: RESISTING THE EFFECTS OF CHANNEL NOISE IN DIGITAL TRANSMISSION OF INFORMATION            Abstract A method for resisting the effects of channel noise in the digital transmission of information by means of the technique known as vector quantization, in which the codebook for binary index code assignment is generated by picking a vector quantized codeword with high probability and low perceptually-related distance from a required group of nearest neighbors, assigning that codeword and those neighbors binary index codes differing only in one bit, repeating the steps just outlined for assigned binary index codes to residual codewords until the lasts assignments must be made arbitrarily. Applications include transmission of speech by coded LPC parameters and transmission of image intensity or chrominance blocks for visual images. Such systems also make possible and are attractive for memory-efficient storage of such signals.

Abstract: DIGITAL PHASE LOCKED LOOP CLOCK RECOVERY SCHEME Abstract A digital clock recovery scheme is disclosed. A reference clock, is used to provide a plurality of N signals with different clock phases. The incoming data stream is sampled and clocked with the reference clock to generate a plurality of M samples for each data bit. The logic values of the M samples are then analyzed to determine the relationship between the current clock phase and the data bit transition. In particular, if all samples agree, the clock phase is correctly aligned with the data. If the clock phase is either leading or lagging the data,various samples will disagree. In the latter situation, the clock phase is adjusted until all samples agree, the particular clock which provides this state thus being defined as the recovered clock signal.

Title: Method for the recovery of mercury from mercury-  containing material
Inventor: BALL DONALD L
IPC: C22B43/00
Filed: 1989-08-25
Granted: 1996-07-23
Abstract: Insoluble   mercury   salts   and   any   mercury    in mercury-containing material are converted into a soluble form by controlled chlorination.  The  soluble  forms  of mercury in the chlorination solution are reduced with iron, preferably  iron  powder,  to  elemental  mercury.  After separation from the reduced solution, the solids from the reduction containing entrained mercury, are subjected to a separation   for   the   separation   and   substantially quantitative  recovery  of  substantially  pure  mercury.          Separation by elutriation through a body of mercury is preferred. Prior to separation, the reduction solids may be kneaded for coalescense of fine mercury   particles, followed   by  slurrying  of  the  kneaded  material.  Any selenium in the  reduced solution may be recovered in a reduction with a suitable  reductant, preferably by adding strong  sulfuric  acid  in  the  presence  of  the  ferrous chloride formed in the preceding reduction, and   excess sulfur dioxide.  The process is carried out at ambient conditions, and the amount of liquid in the  process is controlled. Substantially  no  mercury  is discharged from the process in residues, or residual liquid.

Abstract: Bleaching of a mechanical pulp, such as chemimechanical pulp (CMP), chemithermomechanical pulp (CTMP), and the like, achieves high brightness. A lignocellulose mechanical pulp is subjected to two different peroxide (P) stages (12, 18), and a hydrosulfite (dithionite) (T) stage (20). A P-P-T sequence is preferred (although a P-T-P sequence also produces good results). Bleaching is typically accomplished in all stages at a consistency of between about 8-30%. Between the peroxide stages, the pulp is preferably pressed (19). Between a peroxide stage and a subsequent hydrosulfite stage the pulp is preferably pressed (19 min ), and the pH reduced to between about 5.5-6.0 when diluting with SO2 water (26). The P-P-T bleaching sequence results in pulp with unexpectedly high brightness, brightness levels of about 83% ISO, and greater, being possible.
