Patent DE-4333592-A1 (DE)
Title: Lifting valve with an additional disc
Inventor: TEICHMANN RUEDIGER DR
IPC: F01L1/28
Filed: 1993-10-01
Abstract: In addition to the valve disc, an inlet valve, in particular, of an internal combustion engine has an additional disc displaceably guided along the valve stem, which disc is held at an interval from the valve disc by a spring element. In a known manner the said additional disc acts as non-return valve. A return flow of residual gas into the inlet port is particularly desirable on the other hand during the valve overlap. The additional disc is then fixed in the position close to the valve disc by a locking device. This is achieved by two balls supported in the valve stem which, by suitable means, are pressed slightly outwards and in so doing engage in recesses in the guide part of the additional disc.

Patent DE-4345004-A1 (DE)
Title: Multi-hole injection nozzle with at least two fuel streams for IC engine
Inventor: KRAYSS EBERHARD
IPC: F02M61/18
Filed: 1993-12-30
Abstract: The injection nozzle has at least two fuel streams. These fuel streams have a flow path which crosses the flow path of other flow streams, rather than being directed separately and radially outwards. The fuel is thereby scattered very intensively in the combustion chamber, and this scattering can also be achieved at a lower pressure. Intensive scattering with smaller fuel droplet size also leads to a shorter duration ignition process and slower pressure increase.
Patent DE-4401781-A1 (DE)
Title: Wing for STOL aircraft
Inventor: BENKER GERHARD
IPC: B64C9/18
Filed: 1994-01-21
Abstract: The main wing (2) has a shaped recess (10) under the rear profile into which the secondary wing profile is located during normal flight, to form a complete wing profile with the main wing. For take-off and landing this secondary wing is extended away from the main wing by two support struts (5) hinged between the wings i.e. the wing shape becomes a biplane. The support struts are fitted with servo cylinders at each end to control the extension and to control the relative pitch of the two wings. Additional adjustable flaps (3, 7) at the trailing edges of the two wings enable the aircraft to be trimmed. The extended wing setting can also be used to improve slow speed manoeuvrability.

Abstract: L'invention a pour objet un procede pour allumer un melange de frittage, compose d'un combustible solide et d'un materiau a fritter, dans une machine a fritter dans laquelle le melange est introduit dans un four d'allumage comportant des parois frontale et laterale fermees et un couvercle ferme. Des gaz tres chauds engendres dans le four au-dessus du materiau a fritter chauffent et allument la surface superieure de celui-ci par rayonnement et convexion. On obtient un allumage rapide, uniforme et economique par le fait que des gaz provenant de bruleurs fonctionnant de maniere approximativement stoechiometrique sont introduits dans la partie superieure du four et par le fait que des gaz comportant une proportion elevee d'oxygene sont introduits dans la partie inferieure, le tout de maniere qu'il se forme une atmosphere chaude et pauvre en oxygene dans la partie superieure du four, froide et riche en oxygene dans la partie inferieure. Dans une variante on obtient une amelioration du processus d'allumage en utilisant pour le four une calotte isolee thermiquement. En outre des dispositifs pour la mise en oeuvre du procede sont decrits.
