Patent EP-0472895-A1 (EP)
Inventor: BOHMANN DETLEF DIPL-ING
IPC: F24H9/20
Filed: 1991-07-20
Abstract: An apparatus for controlling the exhaust gas temperature in heating boilers (10) is proposed, in which boilers the exhaust gases are conducted to the outside by at least one exhaust gas flue (11 to 13) which is provided with heat exchange ribs (17) which cool the exhaust gases. A bypass pipe, which bridges at least a part of the at least one exhaust gas flue (13), is designed as a pipe (18) which can be inserted into this exhaust gas flue and the flow outlet end (20) of which bears an element (23, 24) which changes the flow cross-section depending upon the temperature. With decreasing output of the heating boiler, the exhaust gas temperature at the outlet would cool so that there is a danger of formation of condensates. This is prevented in that the element (23) opens in the event of cooling exhaust gas temperature at the outlet, so that the exhaust gases essentially flow through the pipe (18) with decreasing cooling. This pipe (18) for exhaust gas temperature control can be inserted into heating boilers simply and economically, even subsequently. <IMAGE>

Abstract: An electrophotographic toner for negative charging comprises a quaternary ammonium salt having an oxyacid anion as a charge-controlling assistant in combination with a charge-controlling agent for negative charging, a fixing resin and a colorant. The quaternary ammonium salt used as the assistant is incompatible with the fixing resin but dispersible therein. The toner provides a sharp distribution of the charge quantity so that formation of highly charged toner particles which do not contribute to development and of lowly charged toner particles which are easily scattered is effectively prevented.

Abstract: Conteneur de stockage d'éléments combustibles nucléaires épuisés dans des lieux d'emmagasinage intermédiaires. Un élément à boîtier tubulaire (2) comporte des plaques (6, 7) qui s'entrecroisent et créent un certain nombre de compartiments (8) devant contenir un élément chacun. Les plaques (6, 7) sont reliées les unes aux autres de manière fixe sur leurs parties terminales. Leurs parties centrales sont pourvues de fentes qui confèrent aux parois des compartiments (8) une élasticité perpendiculaire au plan des parois. Ceci réduit la résistance due au frottement entre un élément combustible et une paroi de compartiment lorsqu'on y introduit un élément comportant des déformations qui entreront en contact avec une paroi de compartiment. Comparé aux conteneurs de stockage des techniques antérieures, le compartiment a une section transversale réduite et permet d'obtenir une densité de stockage plus élevée.
