Abstract: The invention relates to a method for recovering of fluorescent material from faulty glass bodies (1) of discharge lamps by crushing (11) the lamps, separating and recovering the fluorescent components thereof. The method comprises the steps of breaking the faulty glass bodies (1) in a crusher, removing all metallic component parts if present in the glass bodies (1) by means of electromagnetic separation (13), separating a remaining fraction forming a reusable waste from the broken scrap including glass particles and fluorescent material particles by sieving (15), separating the fluorescent material from the surface of the glass particles in a liquid by washing (19), and obtaining a reusable fluorescent material from the liquid suspension by means of at least one sedimentary deposition (21). The method comprises the step of treating of the remaining fraction by heat for removing the binding material from the fluorescent material if it is necessary.

Abstract: The invention relates to a process for the preparation and use of antidote-carrying maize plant parts which are useful for lowering the cultivated plant-damaging effect of thiolcarbamates and chloroacetanilides, which comprises treating native or artificially genmanipulated macroorganisms living in the soil or on the soil surface by the thiolcarbamate and chloroacetanilides compounds and using the living organisms thus made antidote-carrying for the treatment of field soils in a fresh state or after preservation by lyophilization or by application onto a carrier in their original state or after working up them by crushing, pulverisation, extraction or drying, before or simultaneously with or after the treatment with the herbicides, in any time until the germination of the cultivated plant, whereby the selectivity of thiolcarbamates of the formula (I) and chloroacetanilides against cultivated plants, preferably against the maize is increased.

Abstract: The invention relates to new 4-aryl-2-methyl-1,2,3,4-tetrahydro-isoquinoline derivatives of the general Formula I ##STR1## and salts thereof whereinR stands for hydrogen, lower alkyl or halogen andX represents a group of the general Formula --(CH.sub.2).sub.n --NR.sup.1 R.sup.2, --NH--R.sup.3 or --OR.sup.4, in whichR.sup.1 and R.sup.2 may be the same or different and stand for hydrogen or lower alkyl or R.sup.1 and R.sup.2 together with the adjacent nitrogen atom, they are attached to, form a 5- or 6-membered saturated heterocyclic ring which may optionally contain a further oxygen or sulfur atom or an optionally lower alkyl substituted imino group;n is an integral number 1, 2, 3 or 4;R.sup.3 stands for lower alkyl or optionally substituted phenyl andR.sup.4 is lower alkyl, halogeno lower alkyl, or phenyl lower alkyl.The compounds of the general Formula I are useful as antidepressants and antiparkinsone agents.The compounds of the general Formula I can be prepared by methods known per se.
