IPC: H01M8/04223
Filed: 2001-10-30
Abstract: Die bei höherem Temperaturen über betriebene HT-PEM-Brennstoffzellen sind unempfindlicher gegen CO-Vergiftungen als die bei Normaltemperaturen betriebenen PEM-Brennstoffzellen. Gemäß der Erfindung wird zur Regenerierung etwaiger, durch das Starten der Brennstoffzelle verursachter CO-Vergiftungen vorgeschlagen, die HT-PEM-Brennstoffzellen beim Aufheizen oder im betriebswarmen Zustand für einen vorgegebenen Zeitraum im Pulsbetrieb zu betreiben. Damit kann eine Regenerierung von mit CO belegten Elektroden der Brennstoffzellen erreicht werden. Bei einer Brennstoffzellenanlage mit wenigstens einem Brenn-stoffzellenmodul aus einem Stapel von HT-PEM-Brennstoffzellen (Brennstoffzellenstack) und einer zugehörigen Steuer- und/oder Regeleinrichtung zur Prozessführung ist zur Ausführung des Regenierungsverfahrens der Steuer- und/oder Regeleinrichtung (120) eine Pulseinrichtung (125) zugeordnet, die in Abhängigkeit von vorgebbaren Parametern das Brennstoffzellenstack (110) zum Pulsbetrieb aktiviert.

Title: Low temperature deflashing of mouldings of resilient
Inventor: D JONES ROBERT
IPC: B24B31/02
Filed: 1968-12-30
Abstract: Articles moulded in resilient material are deflashed by placing the article in a tumbling chamber and introducing liquid gaseous material, e.g. liquid nitrogen, to cool the chamber to a temp. substantially below the moulding material embrittlement temperature, maintaining this temperature for a predetermined time while tumbling the articles to remove part of the flash.

Title: Press for compacting refuse for making compost - has transfer container between the storage silo and compacting press
Inventor: STODT EBERHARD
IPC: B30B15/30
Filed: 1973-11-09
Abstract: The compacted refuse bales are stacked and allowed to undergo biological processing in which the refuse is heated and bacteria are destroyed and compost is formed on further standing. Between the shredded refuse silo and the compacting press compacting box is arranged a sliding filling box which ensures speedy operation of the compacting system. The shredded material flows from the silo into the transfer box. This box is pushed along on top of the compacting ram. The compacting process takes place whilst the filling box is held in position and the filling box acts simultaneously as the pressing mould. The ram with the completed bale is withdrawn into the vertical channel whilst the filling box returns to the initial filling position. Subsequently the ram lifts the bale on the level of the transfer table and the bale is removed for stacking. Bales deviating from specified tolerances are separated from the material flow path automatically.
