Title: Hydrocarbon cracking process and device using two successive reaction chambers
Inventor: ESPEILLAC MARCELLIN
IPC: C10G11/18
Filed: 2001-07-03
Granted: 2010-02-02
Abstract: The effluents from each chamber are fractionated in a separate part of the same fractionating column (12) which is partially divided and at least one resulting section (13,44a) from the separate fractionating is totally or partially reinjected into the other chamber. Hydrocarbon cracking in a fluidized bed reactor in which the heat bearing particles, which are also catalytic, circulate in two successive reaction chambers (1,16) in each of which they are put in contact with at least one section of hydrocarbons. The reaction effluents from each chamber are sent to the same fractionating unit. The hydrocarbons injected into the first reaction chamber spend less time there than the hydrocarbons injected into the second reaction chamber, with the time in the first chamber being 0.05 to 5 seconds, preferably 0.1 to 1 second and the time in the second chamber being 0.1 to 10 seconds, preferably 0.4 to 5 seconds. The flow through the first chamber is essentially downwards and that in the second is essentially upwards. In the partially divided fractionating column, the heavier effluents from each chamber are fractionated separately whilst the lighter effluents are combined. The section which is reinjected is a slurry or heavy distillate containing HCO and/or a diesel section containing LCO. The heavy effluents from the first chamber are reinjected into the second. Alternatively, the lighter effluents are fractionated separately and the heavy effluents are combined, with the petrol section from the second chamber reinjected into the first. The reinjected fraction can be mixed with other fractions and/or undergo intermediate treatments before reinjection, such as hydrogenation, hydrodearomatization, hydrodesulfurization or hydrodenitrogenation. Upstream of the second chamber particles are injected both from the first chamber and from a regenerator. Device to carry out this process, comprising a partially divided fractionating column with a zone containing two separate fractionating compartments (38,39) and a common compartment (41). This divided zone can be at the top or bottom of the column and the means of division is a flat or cylindrical vertical wall.

Abstract: A multifilar flexible rotary shaft (100) includes a plurality of individual filaments (102, 104, 106, 108, 110, 112, 114) which are not wound around each other or around a central core, a loose ensemble of filaments. The input ends (1) of each filament are coupled to each other and the output ends (O) of each filament are coupled to each other. Preferably all of the filaments are identical. A loose ensemble of N filaments can transmit N times the torque of a single filament, and will have N times the torsional stiffness of a single filament, while retaining the minimum radius of operation of a single filament. Since a loose ensemble of filaments does not have any appreciable contact forces among the filaments (because they are not forcibly twisted together), there is no appreciable internal friction or hysteresis. In order to appreciably eliminate all the hysteresis in such an ensemble of filaments, the filaments should be no more than loosely twisted together, if at all. The only reason for loosely twisting the wires together is to allow the ensemble to be easily handled and to insure that the individual wire filaments follow the same general curved path from one end to the other. Several practical applications of the invention are also disclosed.

Abstract: The invention concerns a method for operating a front-loading washing machine with a washing aggregate comprising of a tub holding a rotatably-mounted drum suspended in the machine housing so as to be able to oscillate with a midaxis descending from front to back and equipped with an imbalance sensor that changes the rotation of the drum by means of a control program when an imbalance occurs in the spin cycle. In many cases of operation involving small amounts of sensitive types laundry an improved spin result can be achieved, by attending to the preset optimum filling amounts, taking into account the weight and absorbency, and by disabling the imbalance sensor and running the spin cycle at maximum speed

Granted: 2010-01-26
Abstract: A circuit interrupter including a housing having a cover connected to a base, separable main contacts within the housing, and an operating mechanism within the housing and inter-connected with the contacts. A trip mechanism is disposed within the housing and includes a rotatable trip bar assembly that, when selectively rotated, generates a tripping operation. The trip mechanism includes a dual-purpose trip actuator biased upwards and positioned for vertical movement within the housing and having a top portion extending through the cover. The actuator includes a push-to-trip member and an interlock trip member. The trip bar assembly includes a multi-purpose trip member having a push-to-trip actuating region, an interlock trip actuating region, and an accessory trip actuating region. The push-to-trip member contacts the push-to-trip actuating region when the top portion is depressed, causing the trip bar assembly to rotate. The interlock trip member contacts the interlock trip actuating region when the cover is removed from the base, causing the trip bar assembly to rotate. The accessory trip actuating region is positioned to be contacted by the tripping member of the external accessory device and thereby cause rotation of the trip bar assembly.

Abstract: The sulfide ion concentration and sulfidity of kraft cooking liquor during kraft cooking of cellulose pulp is selectively increased. After treatment in a first treatment zone in which impregnation or kraft cooking takes place using a kraft cooking liquor having a first sulfide ion concentration and sulfidity, black liquor is extracted from the material, liquid is withdrawn from the material and dilution liquid is added to the withdrawn liquid and the withdrawn liquid with dilution liquid is reintroduced. In a second treatment zone after the first zone a second kraft cooking liquor is introduced having a second sulfide ion concentration and sulfidity greater than the first sulfide ion concentration and sulfidity (typically by about 20-50%), including by manipulating controlling the flow rate of extraction and the flow rates of withdrawal of liquid and addition of dilution liquid.  The pressure of the continuous digester is controlled in a unique manner that avoids disruptions to the column of pulp continuously moving downwardly in the digester, anywhere in the digester, but particularly avoids non-uniform, unstable material in the countercurrent washing zone. The pressure is controlled by withdrawing liquid from, and introducing liquor into, the digester at at least one additional extraction-dilution loop aside from the main extraction of the digester and the wash dilution liquid introduction mechanism below the wash screens. Pressure can also be maintained (e.g, at about 130-170 psi) by also controlling the amount of wash dilution liquor, and by varying the extraction flow.

Title: Method and apparatus for transmitting information to the surface from a drill string down hole in a well
Inventor: TURNER WILLIAM EVANS
IPC: H04H60/31
Filed: 2001-09-18
Granted: 2011-06-14
Abstract: A method and apparatus for transmitting information to the surface from down hole in a well in which a pulser (12) is incorporated into the bottom hole assembly of a drill string that generates pressure pulses (112) encoded to contain information concerning the drilling operation. The pressure pulses (112) travel to the surface where they are decoded so as to decipher the information. The pulser (12) includes a stator (38) forming passages through which drilling fluid flows on its way to the drill bit. The rotor (36) has blades that obstruct the flow of drilling fluid through the passages when the rotor (36) is rotated into a first orientation and that relieve the obstruction when rotated into a second orientation, so that oscillation of the rotor (36) generates the encoded pressure pulses (112). An electric motor (32), under the operation of a controller (26), drives a drive train that oscillates the rotor (36) between the first and second orientations. The controller (26) may receive instructions for controlling the pressure pulses characteristic from the surface by means of encoded pressure pulses transmitted to the pulser (12) from the surface that are sensed by the pressure sensor (29) and decoded by the controller (26).
