Patent DE-4334571-A1 (DE)
Title: Overrun cut-off device in a motor vehicle internal combustion engine
Inventor: ROSE AXEL
IPC: F02D41/12
Filed: 1993-10-11
Abstract: In an overrun cut-off device in a motor vehicle internal combustion engine in which, on resumption of combustion following an overrun cut-off phase, the ignition timing is advanced from initial "retard" to the required firing point, from the start of the overrun cut-off the quantities of fresh air passing into the exhaust system per power stroke are added up or integrated in order to determine the total quantity of fresh air. The advancing of the ignition timing from initial "retard" to the required firing point proposed on resumption of combustion then occurs at a rate dependent on the total quantity of fresh air in the exhaust system.
Patent DE-4335117-A1 (DE)
Title: Method and apparatus for removing traces of oil from traffic surfaces, in particular roads or the like
Inventor: DIETRICH THOMAS
IPC: E01H1/00
Filed: 1993-10-15
Abstract: In order to enable rapid and optimal removal of oil traces, a liquid chemical binder is applied to the traffic surface. Fresh water is fed to the applied binder, the binder/water combination being worked in on the traffic surface and then fed to a suction device. During the removal by suction, the oil/binder/water combination is fed to a dirty-water tank in which, via a capillary system, the binder/water combination is separated from the oil and is fed to a fresh-water tank.

IPC: F04B1/04
Filed: 1994-03-02
Abstract: The hydraulic piston pump assembly, and especially a high pressure piston pump, has a sliding layer (26) at one sliding section (19, 21) as a solid suspension, with very small particles such as of MoS2, graphite or Teflon (RTM) in an inorganic or organic bonding agent.
Patent DE-4412191-A1 (DE)
Title: Diagnostic device for an exhaust purification system
Inventor: TAKAKU YUTAKA
IPC: F02D35/00
Filed: 1994-04-08
Abstract: A diagnostic device for an exhaust purification system is installed for an engine and comprises a misfire detection device (9 in Fig. 1) which detects a misfire of the engine (1), and a detection device (10) for a malfunction of the secondary air system, which detects a malfunction of the secondary air system (6). An index correction device (13) corrects a deterioration index calculated by a deterioration-index calculation device (11) in accordance with the result detected by the detection device (9 or 10). A deterioration decision unit (12) determines, by using the corrected deterioration index, whether there is a malfunction in the diagnostic device. If the extent of misfiring or the like is considerable, a decision abort unit (14) aborts the decision-making of the deterioration decision unit (12). Thus even if a misfire of the engine (1) or a malfunction in the secondary air system (6) occur, the detection of the deterioration of a catalytic converter (5) is not defective. This avoids mistaken replacement of the catalytic converter (5) which has not yet deteriorated and operation of the engine (1) despite deterioration of the catalytic converter (5). <IMAGE>

Patent DE-4421408-A1 (DE)
Title: IC engine valve spring retainer plate
Inventor: SAILER PETER
IPC: F01L3/10
Filed: 1994-06-18
Abstract: The valve spring retainer plate (1) is punched out (3) and perforated either singly or together on the cone boss (2) and/or the spring (4). Stiffening shoulders are moulded axially and radially onto the retainer plate and where the plate has two springs these are axially and radially offset from one another. The punched holes are curved and lie concentric to the centre of the plate, using alternating punched holes and perforations for preference. Thus in a cast or extruded design, the plate has holes extending from the rim or a punched hole or pleat to limited depth from one side. Pleat or punched holes are in the endface of the spring assembly which is raised on the underside and the hole running from the outside rim of the spring plate is concave in shape so as to form several spring arms as adjoined positively by the retainer plate.

Title: Procede et dispositif de recuperation d'amines et utilisation des residus ainsi obtenus
Inventor: GIEBELER EBERHARD
IPC: C07C209/86
Filed: 1995-05-03
Abstract: L'invention concerne un procédé de récupération d'amines provenant de solutions acides de sel d'amine, par adjonction de bases et évaporation de la solution à un pH compris entre 11 et 13, dans un sécheur malaxeur, jusqu'à obtention d'un solide utilisable, sous forme de résidu de distillation. L'invention concerne également un dispositif de réduction de boues et de suspensions en un solide et une pluralité de fractions liquides séparées en fonction du point d'ébullition. La phase d'amine pauvre en eau séparée par distillation est déshydratée avec de l'oxyde de calcium ou de l'hydroxyde de potassium et est ensuite séparée par rectification en fractions d'amine pures. Ce procédé permet d'utiliser tous les flux secondaires et de recycler complètement les amines et l'absorbant (l'acide sulfurique). Les flux utilisés dans le processus de recyclage sont des acides de lavage chargés en amines, issus d'absorbants, obtenus pendant l'épuration de l'air d'évacuation contenant des amines, produit par ex. lors du processus cold-box utilisé pour le durcissement de sable à noyaux dans les fonderies.
