Abstract: A data word is divided with two words. They are input into an encoder. And parities are generated by input of encoder. However, frequencies of k/2-multiplier are only input in the encoder circuit. Therefore the method of parity generation is conveniently provided. Encoder circuits (EN1) and (EN2) that consist of multiplexer or EXOR gate or register are connected in parallel. Data word is divided with DW1 and DW2. DW1 inputs sequence of higher numerical index and DW2 inputs sequence of lower numerical index. Code word C(x) generates parity P(x).

Title: Apparatus for transferring particles from one zone to another
Inventor: GREENWOOD ARTHUR R
IPC: B01J38/42
Filed: 1986-01-27
Granted: 1989-09-21
Abstract: The catalyst regenerator comprises an upper zone wherein catalyst particles are subject to regeneration by a gas stream flowing radially therethrough, and a lower zone wherein the particles are subject to a gas stream flowing upwardly.  There being gravity flow of particles from the upper zone to the lower zone, sampling of the catalyst particles to determine their level of regeneration is performed in an annular transistor zone located between the upper zone and the lower zone.  The transition zone isolates the upwardly- flowing gas stream from contacting the catalyst particles in the upper zone.

Abstract: The water dispersed resin of acrylated urethane graft copolymer is prepared by synthesizing mono acrylated diisocyanate from cycloaliphatic or aliphatic diisocyanate and acrylic monomers in an egv. ratio of 5:1-30:1; preparing mono acrylated urethane prepolymer from mono acrylated diisocyanate, polyol and bifunctional carboxyl acid with the eq . ratio of NCO to OH is 1.2:1-5.5:1 and neutralizing the unreacted carboxyl acid with amine; making urea bonds by reacting a chain extender with excess NCO groups in prepolymer and dispersion of prepolymer by adding separately or mixedly anionic and nonionic emulsifying agent; reacting the dispersed prepolymer with acrylic monomer in 0.05-5.0% initiator by three steps of pre-emulsion to form seed latex and feed-addition to add monomer and formation of final particle of shell.

Abstract: 본 발명은 능동 전력필터의 보상전류 검출회로 및 그 검출방법에 관한 것으로, 종래의 능동 전력필터는 d-q축의 부하 보상전류값을 구하기 위해서는 전압에 의한 나눗셈을 해야하므로 이 나눗셈에 의한 계산시간이 지연되므로 고조파 보상과 변동하는 부하특성에 따른 보상을 하는데 보상지연이 생기게 된다.  따라서 신속하고 정확한 순시 부하전류 보상을 하기 힘들고 또한 검출부는 고조파 억제, 역률보상, 플리커 제어, 불평형 전류제거 및 전압 변동억제등의 다양한 기능을 하기 위해서는 하드웨어를 수정해야 하는 문제점이 있다. 
     이와같은 종래의 결함을 감안하여 본 발명은 나눗셈을 하지 않고 보상전류를 먼저 D-Q 변환을 행한 다음 위상추적의 위상을 마이크로프로세서를 이용하여 보상전류를 구할 수 있도록함으로써 계산지연 및 보상지연이 생기지 않도록 함과 아울러 신속하고 정확한 순시부하 전류를 보상하도록 한 효과가 있다.
