Abstract: The invention relates to a process for the hydroconversion of heavy and residual oils, spent oils and waste oils, tar sands and the like by contacting with hydrogen at a hydrogen partial pressure between 50 and 300 bar, a temperature between 250 and 500 DEG C, a throughput of 0.1 to 5 tonnes/m<3> and hour, and a gas/liquid ratio between 100 and 10,000 standard m<3>/tonne. The technical object and aim of the invention is to provide a process for processing heavy and residual oils, wherein excessive foam formation is avoided and the reaction space of the hydrogenation reactors is more fully utilised. To achieve the technical object, the catalyst or added additives in the hydrotreatment of the feedstocks has a particle size distribution between 0.1 and 2000  mu m, preferably 0.1 and 1000  mu m, and the fraction of the particles of catalyst or additive having a particle size of 100  mu m or more amount to between 10 and 40% by weight, preferably 10 or 30% by weight, of the total quantity of catalyst or additive added to the reactor system.

Abstract: An industrial compact synchrotron radiation source with improved vacuum to prolong life-time of a charged particle beam. The synchrotron supplies highly stable, intense synchrotron radiation. In the source, a charged particle beam bending duct (1) forming a vacuum chamber through which the charged particle beam circulates, is encompassed by a bending electromagnet (2). At least one SR guide duct (3) for guiding the radia­tion to the outside extends from the outer circumferential wall (1e) of the bending duct. The SR guide duct is connected through a gate valve (5) to an SR beam line duct (7) for guiding the SR beam to an object to be worked on. A vacuum pump (4) is disposed on the side of the gate valve, close to an orbit (A) of the charged particle beam. The SR guide duct extending from the outer circumferential wall of the bending duct takes the form of a divergent duct which is widened in accordance with a spreading angle (ϑs) of the SR beam travelling through the SR guide duct.

Abstract: This device for the selection of the needles comprises a selector (4) accommodated below a needle (5) in a same groove (2) of a needle bed (3) of the machine. The selector is controllably movable from an extraction position, in which a heel (4a) thereof protrudes from the groove to engage with selection cams (6) facing said needle bed, to a sunk position, in which the heel is accommodated in the groove so as to not engage with the selection cams. Between the selector and the bottom of the groove an elastic element (8) is interposed which keeps the selector (4) in the extraction position and a sinking cam (9) is provided, rigidly associated with the selection cams, which causes the passage of the selector from the extraction position to the sunk position in contrast with the elastic element (8). A rod (14) is engageable with the elastic element (8) to keep the selector (4) in the sunk position and actuators (11) controllably act on the rod to cause disengagement thereof from the elastic element (8) so as to obtain the passage of the selector to the extraction position.

Abstract: A control system for a color copier which sets up an adequate color copying time for any particular size of paper sheets. A color document is repeatedly scanned by scanning optics (58) to sequentially expose a single photoconductive drum (52), which is rotated at a constant speed, to a plurality of separated color components. Each of the latent images electrostatically formed on the drum is developed by toner which is supplied from a developing device and complementary in color to the color component associated with the latent image, the resulting toner images being sequentially transferred to a paper sheet which is held on and rotated together with a transfer drum (66). The control system includes a paper size setting circuit (44) for setting the size of a paper sheet to be used before a copying operation, a scanning sensor (86) for sensing the start of a scanning performed by the optics, and a home sensor (88) for sensing an instantaneous angular position of the transfer drum. A control circuit (98) is constructed to determine a transfer start and a transfer end time in response to a paper size signal outputted by the paper size setting circuit (94), an output signal of the scanning sensor (86), and an output signal of the home sensor (88), and to variably control the rotation speed of the transfer drum during the interval between the transfer start and transfer end times so as to register the leading end of a paper sheet loaded on the transfer drum and that of each of the toner images formed on the photocondutive drum and different in color from each other. The circumferential length of one of the photoconductive and transfer drums is greater than that of the other by a multiple other than integral multiples.

Abstract: An industrial robot includes a movable arm and an electric motor driving the arm. A current flowing through the motor is controlled so that the arm is moved into predetermined positions and is balanced in the predetermined positions sequentially. A device memorizes values of the motor current at which the arm is balanced in the respective predetermined positions. A target value of the motor current is calculated on the basis of the memorized motor current values. The target motor current value allows the arm to be balanced in a given position.

Abstract: A phase comparator (70) included in a phase locked loop (PLL) for comparing two input signals with respect to phase to thereby determine their phase difference includes two multipliers (36, 38) and two low-pass filters (40,42) for producing a sine component signal and a cosine component signal which are associated with the phase difference. A discrimination signal representative of a polarity is generated on the basis of one of those two component signals, and a phase error signal is generated on the basis of the other of them. The phase error signal monotonously increases during predetermined one period which is determined by the discrimination signal, i.e. (2n - 1)π to (2n +1)π where  n  is 0, ±1, ±2 and so on. A PLL using such a phase comparator is allowed to rapidly converge to a stable point even when the phase error is close to an unstable point, i.e., ±(2n - 1) where n is 0, 1, 2 and so on, achieving an extremely short acquisition time.

Abstract: A method and apparatus for forming an electrically conductive externally insulated casing for an oil well of the type in which the casing carries electrical current to a primary heating electrode positioned downhole, using multiple prefabricated casing segments; each casing segment is a long steel pipe having a female thread coupling on one end and a male thread on the other end. Each segment has an insulator covering, over substantially all of its length, that has a figure of merit     of no more than 4 x 10 8  so that the the shunt impedance of the casing to ground can be kept substantially greater than the spreading resistance of the primary heating electrode. The preferred casing segment insulation is in two layers, including a hard, durable inner layer subject to water degradation and an outer water-impervious layer usually applied as tape. The uninsulated portions of joints between segments are covered with an insulator cement in the field and then further covered with a water-impervious tape that overlaps the water-impervious layers on two segments.

Abstract: In the method, a distance covered by particles located in the flow is used as a measure of the speed of flow. The particles are illuminated twice in a plane by a light in a prescribed time interval, and light reflected by the particles is received and reproduced in the form of an image. The image is transilluminated by a second, coherent light beam focused in a first Fourier plane and a first Fourier-transformed image is thus generated which is received in turn. The image and the first Fourier-transformed image (23) are immediately displayed. The first Fourier-transformed image (23) is transilluminated by a third, coherent light beam (19) and a second Fourier-transformed image (34) is thus generated optically in a second Fourier plane (33). The second Fourier-transformed image (34) is received and processed further immediately.
