Patent EP-0474361-A1 (EP)
Inventor: HOLLEY ALISTAIR R
IPC: B62H1/12
Filed: 1991-08-02
Abstract: A retractable support 10 for a bicycle 1 comprises a prop 15 adapted to be coupled to the bicycle 1 to be displaceable from a rest position to an in-use position. The prop comprises an angled arm that terminates at one end in an axially rotatable wheel 23, the other end 25 of the arm being coupled to the bicycle 1. A spring 50 urges the prop 10 to the rest position. An abutment 18 is positioned between the ends of the arm, whereby in use, the prop 15 is engageable by the foot of the cyclist to displace the prop 15 against the spring 50 into the in use position where the wheel 23 engages the ground, and downward foot pressure on the abutment 18 holds the prop 15 in the in use position to stabilise the bicycle. Release of the foot pressure causes the prop 15 to be biased to the rest position.

Abstract: A method for preparing anhydrous ferric chloride from a hydrous solution containing ferric chloride that possibly contains organic substances and or ferrous chloride, comprises the steps of:
     a) removing water from a ferric-chloride water solution, or a solution in which at least a portion of the ferrous chloride has possibly been converted by oxidation into ferric chloride, by drying in an atmosphere containing hydrochloric acid; and   b) refining the anhydrous ferric chloride by sublimating it into the gas phase in a chlorine-containing atmosphere and by subliming it into pure crystalline ferric chloride.

Abstract: Dans une combinaison de véhicules comprenant un véhicule de remorquage (1) et une semi-remorque (2), le système de freinage du véhicule de remorquage (1) comporte une soupape (8) qui permet d'adapter la pression de freinage appliquée aux freins de la semi-remorque (3) à la pression de freinage appliquée aux freins du véhicule de remorquage (1). Cette adaptation s'effectue au moyen d'une unité de régulation électronique (16) dans laquelle la décélération effective de la combinaison des véhicules pendant une séquence de freinage donnée est comparée à une décélération anticipée. En cas d'écarts entre ces décélérations, une soupape de régulation (23) est activée, après quoi la soupape (8) reçoit un signal pneumatique grâce auquel la semi-remorque (2) reçoit une pression de freinage plus élevée ou plus basse par rapport à celle du véhicule de remorquage (1), selon que la décélération effective était plus basse ou plus élevée que la décélération anticipée.

Abstract: Bâti vibrant à régulation active (142) permettant de transmettre les forces statiques d'une machine (23) à un support en découplant la transmission des forces vibratoires dynamiques. Le bâti procure une réduction des pertes dynamiques entre une zone d'origine (152) et une zone d'application (130, 132), à l'effet de réguler de manière active les vibrations d'un élément vibrant (23). Ces pertes dynamiques sont rendues aussi faibles que possible en réduisant au minimum la masse et la vitesse du fluide pompé en faisant circuler ce dernier par des conduites courtes et de forte section (144, 146). Le dispositif est conçu de manière à ce que les forces soient dirigées vers l'élément vibrant (23) selon un seul axe (x) et à limiter l'application de forces dans des directions autres que celle selon laquelle il fait effet.

Abstract: Dans le procédé décrit, on procède à l'enrichissement d'un kaolin brut grâce à la technique qui utilise une phase de classification par voie humide pour produire une fraction de kaolin classée ayant une répartition granulométrique (PSD) telle qu'au moins 50% en poids de la fraction présente une dimension inférieure à 0,5 mum ESD et sensiblement 100% en poids de la fraction présente une dimension inférieure à 10 mum ESD; ainsi qu'une ou plusieurs phases dans lesquelles une boue aqueuse du kaolin classé est au moins partiellement égouttée par filtrage. L'amélioration apportée consiste à effectuer au moins l'une de ces phases de filtrage, en amenant la boue de kaolin aqueuse à s'écouler à travers une plaque de filtre en céramique qui se caractérise par une couche de support poreuse et par une couche supérieure de filtrage poreuse. Le rapport entre les porométries moyennes respectives du matériau de la couche de filtrage et du matériau de la couche de base est compris entre environ 2 et 50. La porométrie de la couche de filtrage est comprise entre environ 1 et 3 mum et la porométrie de la couche de base est comprise entre environ 4 et 50 mum. L'écoulement qui traverse la plaque de filtre s'effectue à partir de la couche de filtre en direction de la couche de base et il est produit par la création d'un différentiel de pression fluidique à travers la plaque de filtre.

Le contrôleur à interruptions (110) fournit un registre d'interruptions pour le contrôleur de péripheriques (103) et produit une interruption chaque fois qu'une ou plusieurs des unités commandées par le contrôleur de péripheriques (103) sont activées. Ledit contrôleur de péripheriques (103) entre en mode de faible consommation d'électricité si aucune interruption n'est détectée pendant un laps de temps prédéterminé. Lorsque le contrôleur à interruptions (110) génère une interruption, le contrôleur de périphériques est activé, et quitte le mode de faible consommation et dessert la ou les unité(s) qui ont provoqué l'interruption.

Abstract: In a motor drive (1) of this kind, the function cycles required for the switching-on movement and for the switching-off movement can be precisely matched to the associated requirements, and can also be controlled and monitored satisfactorily by the requisite control devices in a precisely monitored series with mutual blocking of the individual function steps, particularly also in respect of the required safety measures. Therefore, for switching the power circuit breaker on and off, in each case separate linkage arrangements, which are prestressed by an associated spring force accumulator (9, 10), a switching-on linkage (11) and a switching-off linkage (12) are provided which are prestressed together after each switching off process for subsequent switching-on and switching-off of the toggle lever (3) of the power circuit breaker, and, in the switching intervals, are held, by means of latches (14, 15) to be actuated separately in each case for each linkage arrangement, in stand-by position for subsequent switching-on or switching-off. <IMAGE>
Patent EP-0497384-A1 (EP)
Inventor: MALONE GILBERT R
IPC: G01N33/28
Filed: 1987-08-14
Abstract: A method which involves the isolation, analysis and characterization of dispersants present in motor oils is disclosed. The method is particularly useful in connection with the characterization of high molecular weight polybutenyl succinimide dispersants present in finished motor oils so as to provide detailed information with respect to the starting material reactants needed to synthesize such dispersants. The method involves breaking down complexation present in the oil followed by the isolation of the dispersant from the oil via dialysis. The isolated dispersant in the form of a dialysis residue is then acidified and passed through an ion exchange chromatographic column to adsorb acid materials away from the dispersant. Dispersant content and total carbonyl content can then be determined. The dispersant is then subjected to saponification with sodium hydroxide to provide a hydrocarbyl sodium succinate and a polyamine. The saponified material is subjected to further dialysis to separate it from remaining oil and then further acidified. The acidification results in the formation of a corresponding succinic acid and a dialkyl ester derivative. Procedures such as GPC and VPO determinations can then be carried out. Model reactant components can then be prepared and reacted to determine if the reaction product obtained matches the original dispersant being analyzed.
