Title: Injection moulding process for plastics recycling - by injecting recycled plastics core into moulded plastics casing
Inventor: ZIMMERMANN WOLFGANG PROF DIPL
IPC: B29C44/10
Filed: 1990-06-27
Abstract: A plastics recycling process involves (i) injecting virgin plastics (thermoplastics) for partially filling an empty nest mould and then injecting a gas (N2) to press the plastics against the mould wall and cause it to solidify; (ii) relieving the gas pressure and opt. (partially) evacuating the gas; and (iii) injecting recycled plastics as core material, by means of a second plasticising cylinder, into the residual cavity to fill the cavity using one or more gas blasts which, after feeder blocking, subject the core material to post-compression so that sepn. of the core material from the outer skin is avoided. In a modified process, a propellant is included in the virgin plastics, resulting in complete filling of the mould with a foam into which the recycled plastics is injected. ADVANTAGE - The process produces integral mouldings in which the recycled plastics core is hidden and bubbles are avoided.
Patent DE-4021495-A1 (DE)
Inventor: HAERLE HANS A DIPL ING
IPC: F02B3/06
Filed: 1990-07-05
Abstract: An exhaust gas filter, such as a soot filter for a diesel engine, is provided with a filter body disposed in a housing. The exhaust gases flow through the filter body to be cleaned.

Title: Coulometric determn. of water content of plastics - by using humid carrier gas with constant water content to transfer water from oven to cell for reliability
Inventor: MUMCU SALIH DR
IPC: G01N27/42
Filed: 1990-07-25
Abstract: Coulometric determn. is carried out by heating and dehydrating plastics (I), in an oven; transferring the water expelled with a carrier gas (II) into an electrolytic cell, contg. an absorber (III) forming ions on absorption of water, in which the water is absorbed from (II) and decomposed electrolytically; and calculating the amt. of charge needed for electrolysis of the amt. of water expelled from (I). The novelty is that a constant stream of moist (II) is used, which has a constant content of over 5 micro-g water/g (II) (over 5ppm) before entering the oven. USE/ADVANTAGE - The technique is simple and reduces problems with the cell. Deactivation of the cell by impurities other than water is retarded considerably, allowing the cell to be used for many samples before it must be cleaned and regenerated. Electrolysis is continuous whilst the moist (II) stream is introduced, even when (I) samples are being changed and no samples are under test, which is better for cell operation than frequent interruptions. The water content of (II) provides a reliable check of the cell operation between samples, eliminating the need for the usual time-consuming control measurements.
