Abstract: A process for reforming a hydrocarbon fraction having a limited proportion of C₉+ hydrocarbons. A hydrocarbon fraction is separated into a light fractin and a heavy fraction, the light fraction containing less than 10% by volume of C₉+ hydrocarbon. The light fraction is reformed in the presence of a monofunctional catalyst, and the heavy fraction is reformed in the presence of a bifunctional catalyst.

Abstract: A cartridge (11) for a correction ribbon (13) for typewriters comprises a container (12) for a supply reel (38) and a receiving reel (39). A tensioning device (46) comprises a toothed ring (47) on the supply reel (38) and a spring (48) which is pivoted in the container (12) and which has one end engaged with the toothed ring (47) to tension the ribbon (13). The container (12) can be removably fixed to the lower part of a cartridge for a typing ribbon which in turn can be fitted on a support of the machine. The support is movable from a viewing position to a typing position in which the typing ribbon is in front of the point of typing and to a correction position in which the correction ribbon (13) is in front of the point of typing. The receiving reel (39) of the cartridge (11), in use, is capable of co-operating with a feed mechanism which provides for forward feed movement of the ribbon (13) in each correction cycle. For that purpose the receiving reel (39) comprises a series of frontal teeth (66) provided in the lower part of its flange (63), the container (12) comprises an opening (74) and the feed mechanism comprises a ratchet co-operating with the frontal teeth (66) through the opening (74) for a forward feed cycle of the correction ribbon (13) when the support moves between the viewing position and the correction position.

Abstract: A sample of a hydrocarbon oil containing asphaltenes is chromatographically analyzed by forming a mixture of the oil with a weak solvent. The mixture is passed in contact with a column (11) of a stationary phase of fine solid particles of fully functionalized material, followed by a weak solvent. The solvent, after recovery from the column, is analyzed for aromatics by UV-absorption (22) of UV radiation in the range 200 to 400 nm. The absorbance of the UV light by the irradiated eluents across the UV wavelength range is monitored and the integral of absorbance is derived as a function of photon energy across the wavelength range. The magnitude of the derived integral in at least one time interval corresponding with at least aromatics in the eluent from the stationary phase is measured as an indication of the level of aromatics in the oil sample. The weak solvent may be followed by a strong solvent which, in turn, may be followed by a strong solvent which is modified by the addition of a hydrogen bonding solvent. The solvents are analyzed for saturates, aromatics, polar compounds and any asphaltenic materials by the combination of the UV-absorption measurement (22) and a mass sensitive measurement (23) which measures the combined level of the saturates, aromatics, polars and any asphaltenic compounds present. Equipment to perform the fore­going analysis is also described. The analysis can be used for evaluation of an oil and/or for on-line regulation of an oil refining process.

Abstract: A driving device for initiating and maintaining a spinning top (10) in a continuous movement of rotation and precession is described. The driving device (12) comprises a shaft (38) adapted to axially rotate in a tube (32) on which is concentrically fixed a rim (36). A top (10) is hingedly connected by its central post (14) to the end of the shaft (38) nearest the rim (36). The post is able to rotate around the rim through a ball-bearing joint (28) and the friction between the post and the rim causes the top to spin around the rim. By momentarily braking or changing the direction of movement of the shaft by manual contact on the shaft, it is possible to create a precession movement to the spinning top which will raise it above the rim.

      where R⁴, R⁵, R⁶ and R⁷ are independently defined and each is a substituent which does not interfere substantially with a Friedel-Crafts reaction, and a substituted benzene compound, is carried out in the presence of an alkyl halide or, in some embodiments, hydrogen halide, a Lewis acid, and, optionally, a phase transfer agent and a hydride abstrating reagent. In some embodiments, the subject process is specifically carried out in the absence of elemental iodine. The subject process, which may be practiced in an unhalogenated hydrocarbon solvent, produces the desired compounds in a surprisingly high yield, with a surprisingly high selectivity to the desired product, and at relatively high rate of reaction, using better, more convenient or less expensive process methodology than many processes known heretofore.
