Title: Alkali-free demercaptanization catalyst for hydrocarbon compositions
Inventor: KONOVALOV ALEXEI
IPC: B01J23/70
Filed: 2001-03-29
Granted: 2010-10-19
Abstract: A catalyst is intended for the oxidative demercaptanization (sweetening) of hydrocarbons compositions including petroleum, petroleum distillates, gasolines, kerosenes, jet fuels, diesel fuels and heating oils, natural-gas liquids, etc. It may be used in a fixed-bed or fluidized-bed process. A  catalyst consist of an active part and an inert component. The active part contains an oxide of a transition metal of Groups Ib, V-VIIb of the Periodic Table, either Ni or Co oxide, or mixture of oxides of the indicated elements, and transition metal salts, and nitrogen-containing organics. The inert component is an oxide of an element of Groups IIa, III, IV, or Fe oxide, or chemical compound including not less than 95 % oxides of indicated elements, or mixture of the above compounds. A method for a preparation of the catalyst is following: the inert compound is impregnated with aqueous solution of transition metal salt, the resulting product is calcined in air flow for metal oxide formation, and transition metal salt and nitrogen containing organics are deposed from their solution in organic solvent. An application of the catalyst for the oxidative demercaptanisation of hydrocarbon compositions includes passing the latter through the fixed bed or flow bed of a catalyst at 10-80~C, at pressure 1-10 at. The demercaptanisation proceeds in the presence of air or oxygen, or gas, containing not less than 5 % of oxygen.

Abstract: A folding sectional table assembly includes a pair of table sections, each of which includes a frame assembly and a table top. Each frame assembly includes inner and outer leg assemblies, and each leg assembly has an upper tubular member pivotably mounted at its ends relative to a pair of apron members secured to the underside of the table top, for providing pivoting movement of the leg assembly relative to the table top. A latch arrangement selectively maintains the table sections in the folded, storage position, and includes a latch member pivotably mounted to one of the table sections and a catch member stationarily mounted to the other of the table sections. A latch actuator is interconnected between the latch member and the apron members, for disengaging the latch member from the catch member when it is desired to move the table sections away from the folded, storage position. The latch actuator includes an actuator area located adjacent each side of the table assembly, for enabling an operator to easily access the actuator member for disengaging the latch member without having to reach between the table sections when in the folded, storage position.

Abstract: L'invention concerne un système, un dispositif et une méthodologie améliorés de lecture de code à barres comprenant un moteur de lecture de code à barres qui lit les codes à barres apposés sur des objets proches et produit des données de caractères de symbole représentatives de ces codes à barres. Un sous-système d'émission de données, couplé au moteur de lecture de code à barres, communique ces données de caractères de symbole à l'interface de communication d'un système hôte via un lien de communication passé entre les deux. Le sous-système d'émission de données met en oeuvre plusieurs interfaces de communication différentes. Lors d'un fonctionnement en mode de configuration d'interface, le sous-système de d'émission de données cycle automatiquement à travers au moins une des nombreuses interfaces différentes de communication, ce sous-système activant cette interface (en désactivant les autres interfaces de communication) et teste le lien de communication entre cette interface et le système hôte afin d'assurer que l'interface de communication donnée corresponde à l'interface de communication du système hôte. Le fonctionnement en mode de configuration d'interface cesse lorsqu'il est détecté que l'interface de communication donnée correspond à l'interface de communication du système hôte, permettant alors une communication subséquente de données entre le dispositif de lecture de code à barres et le système hôte sur l'interface de communication active. De cette façon, le sous-système d'émission de données peut s'autoconfigurer automatiquement de telle façon que son interface puisse communiquer avec l'interface de communication du système hôte. Le dispositif peut, en outre, s'interfacer avec une variété de dispositifs hôtes différents d'une manière automatique et sans erreur avec une implication humaine minimale, ce qui procure des avantages importants par rapport aux dispositifs classiques de lecture de code à barres. Le fonctionnement en mode de configuration d'interface est mené, de préférence, lorsque le dispositif est mis en route. Les interfaces de communication mises en oeuvre par le sous-système d'émission de données du dispositif et l'interface de communication du système hôte peuvent supporter plusieurs liens différents de communications de données, y compris des liens de données hertziens (notamment lien infrarouge, lien Bluetooth RF, et lien IEEE 802.11b RF), des liens de données série à fils (notamment des liens de décodeur d'interface, RS-232, USB, IEEE 1394, RS-422, et RS-485) ou d'autres liens de données standards (notamment liens OCIA, IBM 46XX, émulation par photostyle, et LTPN).
