  • Publication number: 20210398705
    Abstract: The invention provides a system for pyrolysing organic waste. The system comprises a conical housing (4) configured to temporarily, substantially hermetically, enclose the waste and a mixing device provided with a drive shaft rotatably mounted relative to the housing and a conical mixing body (25) configured inside the housing to fluidise the waste, which mixing body fixedly attached substantially does not touch the housing. The system further comprises heating means (24) for heating the side wall of the housing. This system makes it possible to carry out the processing of organic waste in a batch process. The mixing body prevents a portion of the waste from sticking together by fluidising the waste and keeping it fluidised, whereby the heat generated by the heating means can gradually spread through the waste inside the housing.

  • Publication number: 20080277079
    Abstract: The invention relates to an adapter rail to be disposed in a base frame of a profile rail system which has a section with which it can be fixed releaseably by force and/or form closure within a fitting region of the base frame the adapter rail having a push-in region in order to accommodate a tensible surface material. The force and/or form closure is established by the insertion of the tensible surface material into the push-in region between the section and the fitting region.

  • Patent number: 6924082
    Abstract: The present application describes a method for information storage and data processing comprising the steps of thermo inducing or photo inducing double-bond shifts (DBS) in substituted (4n)-annulenes thus generating transitions between two different conjugation states with at least one substituent. The two different conjugation states are the conjugation on-state and conjugation off-state of the annulene core ?-electrons with the substituent ?-electrons. The present invention is furthermore related to novel substituted (4n)-heptalenes being optically and/or thermally switchable, based on thermal or photochemical double-bond shifts (DBS) as well as methods for their preparation. The (4n)-heptalenes can be used for information storage and data processing devices.

  • Patent number: 5817838
    Abstract: A process for the manufacture of 4,4-disubstituted 5-methylene-1,3-dioxolan-2-ones ("cyclocarbonates") of the formula: ##STR1## wherein R.sup.1 and R.sup.2 each independently signify a saturated or olefinically-unsaturated aliphatic group or an aromatic group, or R.sup.1 and R.sup.2 together form tetra- or pentamethylene, by reacting a corresponding 3,3-disubstituted prop-1-yn-3-ol of the formula HC.tbd.C--C(R.sup.1)(R.sup.2)--OH (II) with carbon dioxide in the presence of a quaternary ammonium or phosphonium salt as the catalyst comprises using a silver salt as a further catalyst. An alkali metal or quaternary ammonium or phosphonium salt of a carboxylic acid can also be used to increase the catalytic performance of the silver salt catalyst. Moreover, the addition of triphenylphosphine serves to accelerate the reaction to some extent. The silver salts catalyze this process significantly better than the previously utilized copper salts.

  • Patent number: 4582641
    Abstract: Compounds of the formula ##STR1## wherein R.sup.1 -R.sup.4 is hydrogen or chlorine, R.sup.5 is --COOMe or --SO.sub.3 Me, Me is an alkali metal cation and X is oxygen, sulfur or selenium,photosensitizers for the conversion of tachysterol into previtamin D are described. The tachysterol content in mixtures of previtamin D and tachysterol can be greatly reduced by UV-irradiation in the presence of such photosensitizers.
