Title: Recycling polymeric material - by splitting into low mol. wt. cpds. in a melt and forming halide(s) from halogen(s) present
Inventor: MENGES GEORG PROF DR ING
IPC: C10B53/07
Filed: 1992-02-04
Abstract: Recycling of polymeric material (I) comprises adding the material to a melt whose temp. is high enough to split the material into low molecular wt. cpds. and the halogens in the material form halogenides with components in the melt whose b.pt. are higher than the temp. of the melt. The melt comprises metal, metal oxides or chemical cpds. with m.pts. below 600 deg.C. The halogen cpds. in (I) which do not form volatile materials at the temp. of the melt or react with components in the melt to form halogenides which decompose at this temp., remain in the melt or pref. easily removable in the slag. The material and its temp. are selected in such a way that the temp. is lower than the m.pt. of the halogenides. ADVANTAGE - The halogen-content of the melt is reduced considerably
Patent DE-4205793-A1 (DE)
Title: Taking samples esp. for waste gas contg. moderately or difficulty volatile cpds. - esp. poly-chloro-dibenzo(p) di:oxine(s) and poly-chloro-benzofuran(s) by sepg. partial stream, passing through dust filter and adsorbent resin and analysing adsorbed material
IPC: G01N1/34
Filed: 1992-02-26
Abstract: Taking samples, esp. of waste gases, contg. moderated or difficultly volatile substances in a gaseous or aerosol phase, involves (a) withdrawing a partial stream, cooling and filtering if necessary, and leading into a sepn. zone in which the substances to be investigated are sepd. and fixed as dust or in the condensate, and (b) after taking of samples is finished, extracting the sepd. substances and passing to an analyser. The novelty is that in analysing organic substances, esp. polychlorinated dibenzo(p)dioxines (PCDD) and polychlorinated dibenzofurans (PCDF), samples of the partial streams are subjected to only a 2-stage sepn., i.e. (c) passage through an inert dust filter, (d) passage through a zone charged with an adsorber (e.g. a synthetic resin adsorber with multi-reticular structure), without previous removal of gaseous water in the waste gas, and (e) finally analysis of organic substances adsorbed in the dust filter and the adsorbent. USE/ADVANTAGE - Appln. is esp. to analysis of waste gas from furnaces, esp. determn. of polychloro-benzene, polychloro-phenols, polychloro-biphenyls, PCDD, PCDF, polybromo- dibenzo(p)dioxines, polybromo-dibenzofurans, polybromo- and polychloro-dibenzo(p)dioxines and -dibenzofurans, and polycyclic aromatic hydrocarbons. The process is independent of the temp. of the waste gas (0-1000 deg.C), the water content (up to above 300 g/cubic m), and the dust content (up to above 1 g/cubic m), and may be continuous or carried on for long periods. The appts. is simple and avoids sec. contamination. The probe and the cartridge contg. dust filter and adsorbent can be replaced in a few mins., and tedious cleaning of the appts. is avoided.

Patent DE-4208743-A1 (DE)
Title: Automatic back-flushing filter esp. for high pressure applications - in which filter elements are back-flushed by rotating nozzles with flow to nozzles via openings in asynchronously rotating control pipe
Inventor: BUEHLING FRANK DIPL ING
IPC: B01D29/11
Filed: 1992-03-16
Abstract: A back-flushing filter consists of a housing or housings with filtrate inlet and outlet and sludge removal connections. One compact nozzle, or multiple coaxial nozzles, rotate inside the filter inserts, which are preferably cylindrical in shape. The nozzles have single or multiple nozzle chambers, and are inclined at an angle Alpha to the hollow nozzle drive shaft. Back-flushing fluid is fed to these nozzles via a control pipe which also rotates and which is connected to the sludge outlet. Making use of the relative velocity of the control pipe with respect to the nozzles, openings (8) in the control pipe slowly and continuously activate the nozzles or nozzle chambers (9) in the filter element (7) which is to be back-flushed. At the same time the previously active nozzles or nozzle chambers are closed, and the flushing process is in this way continued until all the nozzle chambers serving the filter element (7) have become active. If there is more than one filter element, this procedure is repeated cyclically until all of the elements have been cleaned. USE/ADVANTAGE - Especially for automatic back-flushing filters working at high pressure, for example in the cleaning of fuels or lubricants. The pressure drop which takes place during back-flushing, and the rate at which it occurs, are greatly reduced. The efficiency of operation of the filter is consequently improved.

In addition, on both the inlet and outlet side of the plug there are sealing strips each side of the bore of the same material at right angles to the rings, and also bridging the gap. The rings and strips can fit in grooves in the plug or mounting. Both the rings and strips are made of engineering ceramics, metal, graphite or reinforced graphite. ADVANTAGE - Reliability, good sealing, and requires little effort to operate, being particularly for high rates of flow and where the fluid is turbulent and laden with solids.

Abstract: In the production of anionic tenside-containing washing and cleaning agents by granulation in a mixer into which a solid is inserted, undesired reaction heat, discoloration and softening of the mixture can occur if the solid is alkaline and an anionic tenside in acive form is added thereto. These drawbacks can be prevented by (a) the separate production of an anionic tenside-containing mixture which will flow and can be pumped at down to at least 20  DEG C by the partial to complete neutralisation of one or more anionic tensides in their acid form with a basically acting inorganic or organic neutralising agent, (b) adding this anionic tenside-containing mixture to a solid or mixture of solids inserted in a mixer and (c) granulating the components to form a pourable granulate. With full neutralisation in step (a), an organic neutralising medium is added, with partial neutralisation in step (a), an inorganic or organic neutralising medium is added and the solid added in step (b) is, in the case of partial neutralisation in step (a), a basically acting solid or the solid mixture in step (b) contains one or more basically acting solids and the basically acting solid or solids are present at least in such quantities as to ensure the complete neutralisation of the anionic tensides in their acid form.

The polymer has a density which is equal to or greater than 1.260 grm. per CC. and its physical properties are defined by the equations which define flexural strength and fatigue flexural strength. A is equal to or greater than B which is equal to or greater than 23 kg per sq. mm. and B/A is equal to or greater than 0.85 where A is the initial flexural strength and B is the flexural strength after a 90 day immersion of the pin in a phosphate buffer solution at 37 deg.
