CONEX FIBER 

The Japanese fiber conex, which has been available from Teijin since at least

1972, is also poly. It is pro!ce on a relatively small scale as staple fiber of 1.",

#,$ an 9 tex. Teijin state that their process iffers from that !se by ! %ont, an

their patents s!&&est that it is man!fact!re as follows' isophthaloy l ichlorie an

m(phenyleneiamine are reacte in a polar non(basic solvent, s!ch as

tetrahyrof!ran, to pro!ce an insol!ble pre(conensate, which is then f!rther 

 poltymeri)e by ain& an a*!eo!s sol!tion of a wea+ base.

The soli polymer is separate an sl!rries in (methylpyrrolione, which it

is heate to pro!ce a sol!tion of abo!t 2- concentration. This ope is wet(sp!n

!pwars into a co(c!rrent stream of an a*!eo!s coa&!lant containin& abo!t #-

calci!m chlorie at a temperat!re of "-(1---/. The coa&!lant contains abo!t 1.$

 0% on enterin& the bath an abo!t on leavin& it, an methylene chlorie is

!se to extract the 0% form !se coa&!lant before recycle. The wet tow is rawn

in two sta&es, in boilin& water an then on a plate at --($--/, an after crimpin&

is relaxe at abo!t $--/ to improve its hi&h(temperat!re imensional stability.

The properties of /onex fiber are &enerally to those of omex fiber. Its en(

CATALYTIC

Catalytic cracking of gas oil is accomplished over hot micro-

spherical particles of silica alumina catalyst. The catalyst activity

rapidly drops with the deposition of carbon, and spent catalyst

continuously ows out of the bottom of the reactor.

 There are many catalytic reforming processes available

today for the octane upgrading and sulphur reduction of naphthas. The production of aromatics is a feature of most.

Platinum, moblybdenum, chromium oides and other catalysts are

employed in !ed, moving of uidi"ed beds.

 The recycle of produced hydrogen at high pressures prevents

ole!n and diole!n formation and constitutes a highly e#ective

form of chemical treating. $ll the process embody a heater

followed by the catalyst chambers with the facilities for

continuous or intermittent regeneration. The !nal product isisolated from a fractionation stage. %ecycle hydrogen is scrubbed

to remove hydrogen sulphide, from which sulphur or sulphric acid

is manufactured by oidation in a limited current of air.

$. &ake analysis of the sentence of the article and translated

according to eisting rules.

)he Artificial Ar

The scientists at Temple 6niversity in %hilaelphia, %ennsylvania, have

s!ccessf!lly teste a new electro(mechanical arm on a n!mber of patients. The

artificial arm approaches an ieal in the science of prosthetics beca!se it respons

to irections from the brain in m!ch the same way as oes a nat!ral limb, it

replaces the c!mbersome harness(an p!lley arran&ement common to other man(

mae prosthetic ais. The evice ma+es possible ei&ht ifferent limb movement,

ran&in& from elbow benin& to fin&er manip!lation.

To prepare a patient for the electro(mechanic alarm, the scientist mar+s the

location of the chest, sho!ler an bac+ m!scles which control arm movement an

then attaches electroes to the area esi&ne. Tiny electrical imp!lses &enerate by

the brain travel the spinal cor to the nerve enin&s in the m!scles.
