Title: Process for increasing the efficiency of a pre-polymerized catalyst
Inventor: EWEN JOHN A
IPC: C08F4/60
Filed: 1987-10-12
Granted: 1995-07-25
Abstract: The invention provides a process for pre-polymerizing olefin polymerization catalysts and a process for increasing the efficiency of pre-polymerized olefin polymerization catalysts. In one process of this invention an olefin monomer is added to a fluid carrier stream containing an olefin polymerization catalyst. The carrier stream containing the monomer and the catalyst is passed through an elongated tubular reactor at a flow rate sufficient to provide a residence time in the tubular reactor of less than 1 minute and under temperature conditions to pre-polymerize the catalyst within the tubular reactor without plugging of the reactor. In another process of this invention a pre-polymerized catalyst is contacted with a cocatalyst or a mixture of cocatalyst and an electron donor prior to introducing the catalyst into a polymerization reaction zone. <IMAGE>

Title: Method for calibrating appliances for the measurement of force or moment and appliances relating to the method
Inventor: SARRAZIN MICHEL
IPC: G01L25/00
Filed: 1988-11-19
Granted: 1992-08-06
Abstract: In order to calibrate an appliance for measuring force or moment, the measuring element (l) carries a strain gage bridge (R1, R2, R3, R4) for delivering a signal which is mainly sensitive to the force or to the moment to be measured and is provided at the time of manufacture with two other strain-gage bridges (R5, R6, R7, R8); (R9, R10, R11, R12) for delivering signals which are mainly sensitive to two parasitic stresses other than the force or the moment to be measured. In a first stage, the method consists in measuring the signals delivered by the three strain-gage bridges in the absence of any load applied on the measuring element, then under a number of known reference loads chosen from among those to which each strain-gage bridge is the most sensitive. In a second stage, the reference measurements are used as a basis for calculating the parameters of sensitivity according to which each of the signals delivered by the measuring bridges is a function of the applied loads. In a third stage, these parameters of sensitivity are used as a basis for calculating the correction to be made in the force or the moment measured by the first strain-gage bridge (R1, R2, R3, R4).

Abstract: Nonwoven wiper having improved absorbency characteristics and streak-free wiping properties having a laminate construction including a relatively high basis weight middle layer of meltblown thermoplastic microfibers with fibers added and, on one side, a lightweight layer of generally continuous filament thermoplastic fibers having a larger average diameter with a microfiber layer on the other side. These wipers are strong, fabric-like, and are useful for a wide variety of applications including industrial uses, food services, as well as many others. The continuous filament layers provide strength and low lint properties while the combination exhibits improved wiping characteristics. The laminate is preferably bonded by application of heat and pressure and the individual compounents are preferably treated with a surfactant. The preferred combination of a layer of meltblown polypropylene microfibers with fibers added having on one side a spunbonded polypropylene filament layer and on the other a microfiber layer is particularly effective as an all-purpose wiper.

     이와같이 얻어진 중합형 수지는 전기 절연물(특히 인쇄 회로 기판용), 항공기 구조물(구조물 지지용), 접착제로서, 더나아가 난연성 수지가 필요한 어느 경우에나 사용될 수 있다.
Patent KR-100228606-B1 (KR)
Title: Chemical synthesis of oligonucleotides
Inventor: PFLEIDERER WOLFGANG
IPC: C07H19/16
Filed: 1991-09-13
Granted: 1999-11-01
Abstract: The use of a dansylethoxycarbonyl group as base-labile 5'-hydroxy protective group in the chemical synthesis of DNA and RNA and suitable synthetic processes. The ease of detection of the dansyl protective group and the ease of elimination from the sugar residue of the nucleotide without side reactions make it possible to synthesise oligonucleotides in minute amounts with high yields.
Patent KR-950006474-B1 (KR)
Title: Arranging method of word line
Inventor: DO JAE-IK
IPC: H01L27/108
Filed: 1991-12-17
Granted: 1995-06-15
Abstract: The method includes aligning metal layers (M1-Mn) at predetermined intervals, forming contact regions (10) on pairs of the neighboring metal layers (M1,M2 ; M5,M6) in a first area (300), and forming contact regions (10) on the other neighboring metal layer pairs (M3,M4 ; M7,M8) in second and third areas (300', 300") to align the pitch of contact regions at two word lines intervals, thereby reducing the number of poor processes to reduce the chip size.
Patent KR-940008206-B1 (KR)
Title: High voltage switch circuit
Inventor: LEE UNG-MU
IPC: H03K17/10
Filed: 1991-12-28
Granted: 1994-09-08
Abstract: The high voltage switch circuit includes a decoupling circuit having an enhancement transistor and a depletion transistor having respective channels serially connected between an output terminal of a buffer circuit and an input terminal of a high voltage pump circuit and having respective gates commonly connected to a power voltage terminal, thereby highly integrating a semiconductor memory device.
