Title: Cryogenic rectification method and apparatus
Inventor: ROBERT A MOSTELLO
IPC: B01D3/14
Filed: 1995-06-01
Granted: 1995-12-01
Abstract: A cryogenic rectification method for producing a product stream from a gaseous mixture having higher and lower volatility components and heavy impurities. In accordance with the method, the mixture is separated by a cryogenic rectification process employing one or more columns having plates, trays or packing for intimately contacting ascending vapor and descending liquid streams within the column. The mixture to be separated after having been compressed is combined with the recycle stream to produce a combined stream which is purified in a prepurification unit that is designed to remove the heavy contaminants. The combined steam is divided into major and minor streams. The majorstream is then cooled and separated into liquid and vapor phases. Heavy impurities concentrate in the liquid phase taken as the recycle stream, which is then pumped to a high enough pressure for vaporization of the impurities. The resulting vapor is then reduced in pressure and combined with the incoming gaseous mixture. The concentration of heavy impurities in the vapor phase is reduced to a sufficient extent such that a product stream concentrated in the lower volatility component will have a reduction in its heavy impurity concentration. The product stream is pumped to pressure and vaporized against a portion of mixture using a boosted pressure subsidiary stream made up of a minor portion of the gaseous mixture.

IPC: G02F3/02
Filed: 1996-06-15
Granted: 2002-02-01
Abstract: A light control substance having a negative input-output characteristic is used to invert optical signals. The light control substance is an absorbing substance and has a multi-level energy structure such that ground state absorption occurs between a ground level (E1) and a level (E3) higher than the ground level (E1) and excited state absorption occurs between an excited level (E2) and a level (E4) higher than the excited level (E2). At a specific wavelength, a variation Δ Iout in the intensity of output light and a variation Δ Iin in the intensity of input light satisfy the following equations: Δ Iout = [1-Α1(1+Α2γ)]Δ Iin (1); Α1(1+Α2γ) > 1 (2), where Α1 is an absorbance of the ground state absorption, Α2 is an absorbance of the excited state absorption, and γ is a ratio of electrons relaxing from the level (E3) higher than the ground level (E1) to the exited level (E2). As a result, the value of Δ Iout/Δ Iin becomes negative.

Title: Method and system for three-dimensional compression of digital video signals
Inventor: NIESEN JOSEPH W
IPC: G06T9/00
Filed: 1997-01-11
Granted: 1999-07-11
Abstract: Methods for compressing digital video signals that fully utilize temporal compression techniques. Each of the methods disclosed compresses digital video signals not only in the spatial domain, as with current implemented MPED compression methods, but also in the temporal domain. A group of video signals is input to a signal compressor (16). The signal compressor (16) performs discrete cosine transforms in both the spatial and temporal domain. The transformed data is then input into a three-dimensional quantization matrix (18), where rate and distortion optimization parameters are calculated for compression purpose. In a first method, rate-distortion performance and transmission order are optimized for the quantized, three-dimensional transform coefficients. In a second method, rate-distortion performance is optimized for the quantized, three-dimensional transform coefficients. Temporal dequantization and inverse transform are performed before transmitting the two dimensional coefficients in MPEG-compatible intraframe format. The data is transmitted to a signal decompressor (40).
