Abstract: Procédé de traitement de données et d'optimalisation d'un réseau neuronal permettant de déterminer des données relatives aux caractéristiques physiques de produits à base d'hydrocarbure à partir d'absorbances spectrales dans (le proche) infrarouge (P)IR. Ce procédé consiste à: a) mesurer les spectres (P)IR d'un grand ensemble d'échantillons de produits d'hydrocarbures provenant d'une grande variété de sources; b) choisir une région de l'harmonique supérieure de ces spectres (P)IR ainsi obtenus; c) sélectionner un certain nombre de longueurs d'onde discrètes dans chaque spectre (P)IR, convertir un certain nombre desdites longueurs d'onde en données d'absorption, et utiliser ces dernières comme entrées dans un réseau neuronal; d) effectuer l'apprentissage du réseau neuronal pour tout l'ensemble de données par la présentation répétée d'entrées et de sorties connues, en d'autres termes les données de proche-infrarouge relatives au produit d'hydrocarbure et des données de caractéristiques physiques pertinentes de ce produit, afin que ce réseau apprenne le rapport entre les deux, et surveiller les performances de ses prédictions par rapport aux données de caractéristiques physiques réelles telles que mesurées selon des procédés standards pour les données d'apprentissage, ce qui permet de corréler les valeurs d'absorbances avec lesdites caractéristiques physiques pertinentes; e) générer un ensemble de valeurs pour les distorsions et les pondérations d'interconnexion du réseau, telles qu'ajustées après la période d'apprentissage (d); et f) appliquer ces valeurs ajustées, à l'aide de l'algorithme du réseau, aux spectres du (proche) infrarouge, obtenus dans les mêmes conditions, pour des produits d'hydrocarbure présentant des données de caractéristiques physiques inconnues.

Abstract: The invention relates to a paper roll holder with brake for dispensing use of paper rolls or the like. The paper roll holder comprises a heavy base (1) to which two column-like parts (2a) and (2b) are fixed, against which the paper roll rests and in between which the paper runs and which at their ends have suitably shaped cutting edges or serration, if the paper web is not perforated. A ring and wedge-shaped part (3) as well as a cover (5) with a spring (7) fixed to it are mounted in bearings to parts (2a) and (2b) and a spring (9) fixed to the base are all pressing the paper roll against the column-like parts (2a) and (2b). The form, roughness and weight of parts (3) and (5) and the spring forces of springs (7) and (9) are chosen so that by pulling the paper it easily unwinds but the paper breaks off with a little jerk using only one hand. In the roll holder also rolls without core can be used and then springs are not needed, or the holder can be built without the ring-shaped part (3), in which case only springs (7) and (9) press the paper roll against parts (2a) and (2b). The holder is normally placed on the table but can also by transforming the base be fixed to the wall.

Abstract: Une fraction d'hydrocarbures lourds provenant du craquage en présence d'hydrogène de carburants ayant des températures d'ébullition dépassant environ 316 °C (600 °F) et contenant au moins environ 10 % en poids d'hydrocarbures aromatiques est convertie en un produit de base d'huile lubrifiante à teneur diminuée en hydrocarbures aromatiques sur un catalyseur contenant une matière cristalline qui a une capacité de sorption particulièrement élevée, par exemple supérieure à environ 15 g de benzène pour 100 grammes de cristaux anhydres à 7 kPa (50 torr) et 25 °C et un agent actif pour les réactions d'hydrogénation/de déshydrogénation, de préférence le palladium. La réaction s'effectue dans des conditions de pression élevée permettant de réduire la teneur en hydrocarbures aromatiques à environ 10 % en poids. La fraction lourde est déparaffinée avant l'hydrogénation à haute pression sur un catalyseur contenant la zéolithe HZSM-5, pour diminuer le point d'écoulement de la fraction à -7 °C (environ 20 °F). Normalement, la fraction lourde est produite dans un procédé de craquage en présence d'hydrogène de carburants sous une pression modérée, utilisant un catalyseur bifonctionnel amorphe.

Abstract: Improved cleaners for hard surfaces, cooking utensils, laundry and other substrates that can accumulate fatty soils can be cleaned using an aqueous cleaner made from a cast solid cleaning system. The cast solid system contains a carefully balanced formulation of cleaning ingredients that provide surprising animal or vegetable fat removing properties. The cleaning system can be manufactured in the form of a large bulk cast block. Such blocks are dispensed by spraying a dispensing spray of water onto the surface of the block creating an aqueous concentrate that can be directed to a cleaning site. The solid composition contains a unique blend of a specific amine oxide combined with anionic sulfonates in a solvent containing mass. These unique components cooperate to prove a substantial level of animal or vegetable fat removal in preferred cleaning protocols.

Abstract: An edge of a cylinder bore hole of a base plate is folded back on the base plate to form a double-layer folded portion, and a soft member is held in the inside of the folded portion. Folded portions are also formed by folding an outer peripheral edge of the base plate at positions along a straight line which passes through center points of bolt holes which are located at each side of a reference line passing through center points of cylinder bore holes. The straight line is parallel with the reference line. Further folded portions are formed by folding the outer peripheral edge of the base plate at positions along a further straight line which passes through center points of bolt holes which are located at both sides of the reference line so that the further straight line is orthogonal to the the reference line. Rubber beads made of silicon rubber are formed on both joining surfaces of the base plate to bound each of the cylinder bore holes and the bolt holes.

Abstract: To allocate time slots to terminal stations (T1 ... Ti ... Tn) for transmission of upstream burst (UB) in a network system wherein a central station (CS) is coupled to a plurality of terminal stations (T1 ... Ti ... Tn), the central station (CS) downstream transmits access grant information (AGI) which forms part of downstream frames (DF). 
     Each terminal station (Ti) is equipped with a cyclic local grant counter (LGC) which generates a local grant counter value between zero and a predetermined limit, and which is synchronized with a cyclic master grant counter (MGC) included in the central station (CS). The upstream time slots are bounded by two zero crossings of the cyclic local grant counter (LGC) and a terminal station (Ti) is allowed to transfer an upstream burst (UB) in such a time slot provided that this time slot is allocated to the terminal station (Ti) via previously received access grant information (AGI).
