Patent EP-0530341-A1 (EP)
Inventor: PFALZGRAF BERNHARD
IPC: F02P5/152
Filed: 1992-03-18
Abstract: L'invention concerne la régulation des détonations d'un moteur à combustion interne à allumage par étincelles, ladite régulation s'opérant sur une courte durée et avec une action de régulation relativement grande (périodes a, b, c, f). Lorsque les autodétonations se produisent, la valeur d'un point d'allumage réel est réculée à partir d'une valeur prédéterminée du diagramme caractéristique (alphaV) dans le sens de l'allumage retardé (SK1). Lorsqu'il ne se produit plus le phénomène d'autodétonation, on ramène le point d'allumage réel vers une position d'allumage avancée pour reprendre la valeur prédéterminée du diagramme caractéristique (RK1). Selon l'invention, on effectue une adaptation à long terme de manière que la valeur prédéterminée du diagramme caractéristique (alphav) soit reculée de la limite de résistance à l'autodétonation par une valeur d'adaptation (LZ) ou modifiée lorsque des phénomènes d'autodétonation (K) se produisent, de sorte que la régulation à court terme soit liée à une nouvelle valeur de point d'allumage prédéterminée ou à un autre niveau (alphaLZ). Un changement vers une action de régulation plus faible (période e; SK2, RK2) a lieu après l'adaptation et après un nombre minimum d'allumages sans autodétonation (zone d). Un angle d'allumage plus avancé et une efficacité accrue du moteur à combustion interne sont ainsi normalement obtenus.

IPC: A61M5/31
Filed: 1992-02-27
Abstract: A safety syringe of the type having a needle shield that is slidable between a needle exposing retracted position and a needle protecting extended position and wherein the needle shield is rotatable in the extended position to a locked and extended position. The safety syringe includes a collar mounted on the distal end of the syringe and a plurality of elongate keys on the interior surface of the needle shield. The keys are slidably received in various protrusions and slots on the collar to releasably retain the needle shield in the retracted and extended positions and to retain the needle shield in the locked and extended position. A needle sheath is also removably mounted on the distal end of the needle shield to cover the needle of the syringe when the needle shield is in the initial retracted position.

IPC: G01N21/27
Filed: 1992-01-24
Abstract: A species-specific metal clad segment on a waveguide, including a planar waveguide, allows controlled light leakage of light propagating through the waveguide by total internal reflection, to measure refractive index and identify chemical species. A waveguide sensor is designed for a particular chemical species by selecting a metal clad with an affinity for the species and by matching the refractive indices of the waveguide body, clad, metal clad segment and chemical species. Dual or multiple measurement methods use a pair or multiple metal clad segments of different specificity. The metal clad segment may include another material to provide a suitable refractive index while having the desired affinity for the chemical species or to provide a catalyst to react the species to form a reaction product which is more readily detected.

Abstract: On décrit un procédé concernant la production en continu d'acide 2,6-naphtalènedicarboxylique par oxydation en phase liquide de 2,6-diméthylnaphtalène. Il convient d'ajouter en continu dans une zone de réaction des composants de réaction d'oxydation qui comprennent du 2,6-diméthylnaphtalène, une source d'oxygène moléculaire, un solvant contenant un acide monocarboxylique aliphatique, ainsi qu'un catalyseur contenant des composants à base de cobalt, manganèse et brome, où le rapport entre les atomes de manganèse et de cobalt est d'environ 5:1 à environ 0,3:1, ces deux éléments représentant au moins environ 0,4 % en poids par rapport au poids du solvant. Il convient ensuite de maintenir le contenu de la zone de réaction à une température d'environ 370 à environ 420 °F à une pression suffisante pour maintenir au moins une partie de l'acide monocarboxylique en phase liquide, ce qui permet d'oxyder le 2,6-diméthylnaphtalène en acide 2,6-naphtalènedicarboxylique. En respectant le procédé inventé, on peut produire en continu et à haut rendement cet acide 2,6-naphtalènedicarboxylique avec de faibles niveaux d'impuretés.

Abstract: A high speed anti-friction bearing includes an internal impeller mechanism to provide improved high speed lubrication for the anti-friction elements (15). At high bearing speeds the impeller mechanism (33) scoops liquid lubricant from a liquid annulus centrifugally generated on the outer wall (11) of the bearing. The scooped liquid is hurled inwardly onto the anti-friction elements (15) as a fine mist. The bearing lubrication process is achieved with minimum heat generation and minimum energy loss insofar as the anti-friction elements do not plow through large masses of lubricant.

Abstract: Radio alarm systems having a multiplicity of information channels for transmitting signals (messages, information) between glass break detector, break (opening) detector and the like, and a microprocessor-controlled central unit are known. The individual information channels are in this case formed in accordance with the time-division-multiplexing method or by using the frequency-division-multiplexing method. To increase in a simple manner the interference immunity and to permit signals to be transmitted simultaneously and in an interference-free manner via the different information channels, the information channels are formed, in the transmission direction from the detectors to the central unit, by using the code-division-multiplexing method. The spread information channels thus formed are then superimposed on each other and converted to a single carrier frequency. <IMAGE>
