Title: Pressurisable tubing - has layer of rubber with reinforcing fibres oriented along tube, and with outer fibre-free boundary layer(s)
Inventor: SEMPF HORST DR
IPC: B29C48/10
Filed: 1989-04-08
Abstract: Pressurisable tube structure (I) comprises basically single layer of natural or synthetic rubber interspersed with longitudinal and transversely oriented reinforcing fibres; the  novelty is that (a) the tube wall contains 3-8 wt.% fibre w.r.t.  rubber, (b) the fibres are a mixt. of different  lengths of 2-10 mm, with the mixt. comprising definite lengths with no basic pref., (c) the fibres are incorporated basically randomly, so as to favour orientation along the tube rather than around its circumference and (d) the wall has an outer, and pref. also an inner, boundary layer free of fibres. Process for the prodn. of (I) is claimed, in which (a) the fibres are incorporated mainly longitudinally when producing the sheet rubber which is suppliled to the extruder, and thus pre-oriented in the longitudinal direction, (b) the rough sheet is plasticated by heating in the extruder and mixed further and (c) the outer layer of the mixt. is subjected to a sharp increase in temp. immediately before it enters the injection moulding die. USE/ADVANTAGE - (I) is useful as small-dia. reinforced  tubing, e.g. for applications in the motor vehicle industry.  Curved tubing of any form can be produced directly from the moulding die, and the tube does not suffer from the disadvantages of prior-art prods., esp. "drainage" or "channelling" due to high proportion of traverse fibres penetrating the thickness of the wall.

Title: Decontaminating waste water contg. cyanide using sodium hypochlorite - controlling feed time and rate of hypochlorite to limit concn. of chloro-cyan
Inventor: POHL KURT M DR ING
IPC: C02F1/76
Filed: 1989-10-30
Abstract: In decontamination of waste water contg. cyanide using  NaOCl, the water is heated to 30-80 deg.C and maintained at this temp., and NaOCl is fed into the reactor after the introduction of the water has started. The time delay is adjusted to give a definable limit to the concn. of CNCl formed, and the feed rate of NaOCl is controlled to limit this concn., pref. to not above 10 ppm by wt. If the limiting value is exceeded, the feed rate of NaOCl is lowered. The NaOCl feed is delayed after the end of the feed of waste water, and the ending of the NaOCl feed depends on the CNCl concn. The redox potential is used as actual value of the CNCl concn. The waste water is heated by a heat-exchanger (14) or by feeding steam into a condenser (40,41) or into the waste water feed line.  To control the temp., or for cooling at the end of the reaction, the waste water in the reactor (15) is led through a heat-exchanger. The process may be continuous. The temp. is 50 deg.C and the pH of the liq. in the reactor (15) is 10-12. ADVANTAGE - A high processing rate and efficiency are obtd., at a lower concn. of chlorocyan (CNCl) formed. Overheating is avoided, without slowing down the feed of NaOCl.
