Patent EP-0121376-A2 (EP)
Inventor: LUTZ IRVIN H
IPC: C10G67/04
Filed: 1984-03-20
Abstract: A process for upgrading a heavy viscous hydrocarbon, for example, rendering a heavy viscous crude pipelinable, includes visbreaking, distillation and solvent extraction steps. A heavy viscous hydrocarbon is fed through the visbreaker which forms a feed to the distillation step. A heavier fraction from distillation is fed to a solvent extraction unit which produces a fraction which contains resin. At least a portion of the resin containing fraction separated in the solvent extraction unit is recycled and combined with the feed which is to be subject to visbreaking so that the total yield of products, residual and gas-free, is increased. The recycled resin reduces the tendency of the asphaltenes to separate from the oil and thereby reduces the tendency to lay down coke in the visbreaker; this allows higher conversion to upgraded liquid products.

Abstract: The device consists of a T-shaped pipe piece (1) onto which can be placed a fixture which has a base plate (2) and a housing (7) which can swivel relative thereto. This housing (7) contains two chambers (8, 9), one for holding the peg (1d) closing the branching piece (1b) of the T-piece and the other in which a support (16) carrying the measurement device can be displaced parallel to the axis (33) of the branching piece (1b). A first securing device (28, 29, 30) ensures that the chamber (8) which is used for holding the peg (1d) cannot be opened as long as it is located above the opening (2a) of the baseplate (2). A second locking device prevents downwards movement of the support (16) as long as the second chamber (9) is not located above the opening (2a) in the baseplate (2). The two safety devices act independently from one another to prevent the housing rotating back into the original position as long as the support (16) and the closing slide (10) from the chamber (8) are not moved back to their original position. <IMAGE>

Abstract: An apparatus for automatically filling bags with a material after separating each bag from a continuous chain of bags along perforations where each bag is joined to its neighbor has a guide section for guiding the chain of bags, a separating section for separating the chain of bags into individual bags at the perforations, a mouth opening device for opening a mouth located at one side edge of each bag, and a filling section for blowing air into the bag through its opened mouth and for filling the bag through the opened mouth. The mouth opening device has a pressing assembly supported above the mouth of the bag, and a chuck assembly situated at one side of the mouth. The pressing assembly has pressing pads brought into pressured contact with an outer surface of one side sheet of the bag near its mouth, and the chuck assembly has means for moving the pressing pads toward the bottom of the bag while the pressing pads are in pressured contact with the one side sheet, and means for grasping the other side sheet of the bag at the mouth thereof as the pressing pads are moved. The mouth opening device thus grasps one side sheet of the bag and partially opens the mouth, in which state the bag is delivered to the filling section to be fully opened by the expelled air and filled while held firmly in place.

The screw has at the screwthread a thread diameter and between the turns of the thread at the surface a root diameter smaller than the thread diameter. An anchor sleeve normally fitted in the bore and of an outside diameter corresponding generally to the diameter of the bore has an outer end formed with a laterally projecting rim normally lying against the bone around the bore, an outer end portion of an inside diameter greater than the root diameter but smaller than the thread diameter, and an inner end portion of an inside diameter smaller than the root diameter. Thus when the screw is threaded into the sleeve its thread cuts into the outer portion without substantially deforming and spreading same and into the inner portion with substantial outward deformation and spreading of same.

Abstract: a A cold-rolled strip manufacturing apparatus, in which a continuous cold reduction mill (26) and a continuous annealing furnace (32) are directly linked together, has a tension-leveller-type scale breaker (7) for elongating hot-rolled breakdown by not more than 7 percent, a scale scrubbing brush unit (11) and an immersion-type continuous pickling tank (14) installed upstream of the continuous cold reduction mill (26). 
     Descaling of the hot-rolled breakdown is carried out by breaking the mill scale formed on its surface by causing the running breakdown to elongate and then removing the broken scale from the surface. Percent elongation is feedforward controlled on the basis of the manufacturing conditions of the hot-rolled breakdown and/or the properties and quantity of the mill scale formed. In another descaling method, percent elongation is feedback controlled on the basis of the condition of scale breaking and removing that is detected during the period in which the mill scale is broken and removed.

Abstract: A transducer comprises a drive member (24) and a sense rotor (22) having confronting capacitively coupled electrode faces, each face of which comprises a circular pattern of electrodes (38,44) relatively rotatably mounted in concentric relationship. 
     Either the drive member or the sense rotor, or both, are provided with a set of curved electrodes (38,44) which are slanted or swept back with respect to one direction of rotation. 
     The electrodes (38) of the drive member (24) are completely interdigitated using a plurality of successively phase shifted, time varying drive voltages, coupled (at 5,6,7,8) individually to a corresponding plurality of drive member electrodes (38). 
     Pickup signal errors are minimized by a three dimensio­nal sense rotor (22) in which the sense electrodes (44) are coupled to an isolated pickup electrode (48) disposed adjacent the axial face of the sense rotor opposite that of the sense electrode face. 
     The drive electrodes (38) and the sense electrodes (44) are configured to provide capacitive coupling between a single drive electrode and a single sense electrode that closely approaches a pure sine wave   as a function of the angular displacement of the sense rotor (22) with respect to the drive member (24). 
     The sensed phase angle is used to provide an accurate digital indication of position which can be read by a microprocessor or other controller.

Abstract: An input waveform signal is converted in an A/D converter (6) into a digital signal to be written in a waveform memory (7) under control of a tone generation control unit (8). The written digital signal is read out from the waveform memory (7) with a designated delay time. The input waveform signal and the digital signal read out from the waveform memory (7) are converted in a D/A converter (10) into analog signals which are fed through VCFs (12a-12d) and VCAs (13a-13d) so as to be sounded. Further, in the above arrangement the timbre and tone volume controls are done independently for the individual waveform read/write channels through VCFs (12a-12d) and VCAs (13a-13d). Thus, it is possible to obtain a further effected sound.

Abstract: The invention relates to the control of a power converter in which the AC side is connected through a reactor to an AC power supply while the DC side is connected to a smoothing capacitor and a load and the power rectification and the power inversion are carried out by the pulse width modulation control. The controls performed include (l) the control, whereby the voltage across the smoothing capacitor coincides with a predetermined value and the current flowing through the reactor and the voltage of the AC power supply have a predetermined phase relationship; (2) the DC component compensation control for eliminating the DC component in an AC circuit within a short time interval and (3) the control of the power conversion operation by utilizing a microprocessor while suppressing the higher harmonics in the AC power supply. The control (l) is performed by using an amplitude signal of the voltage on the AC side of the power converter and a phase difference signal relative to the AC power supply voltage. The control (2) is performed by using the amplitude signal and the phase signal on the AC side of the power converter which cause the current flowing through the reactor to have a predetermined phase relationship with the AC power supply voltage and a detected DC component signal flowing through an AC circuit. The control (3) is performed by using the data of degree of modulation and the phase angle data which are fixed value during a certain period of time and the cross point data stored in the storage means.
