Patent BE-766150-A (BE)
Title: Petroleum coke desulphurised demetallisedwith synthesis gas
IPC: C10L9/02
Filed: 1971-04-22
Abstract: Petroleum coke of high sulphur content and contaminated with metals is purified and calcined to form metallurgical grade coke by (1) pre-oxidising the coke at 650-850 degrees F to increase its surface area., (2) hydrosulphurising the coke with synthesis gas at 1300 degrees F or above, and (3) demetallising the coke by contact at 275-430 degrees F and elevated pressure with the H2S-containing synthesis gas effluent from the hydrodesulphurisation step to form gaseous carbonyls of the metals, the H2S functioning as catalyst. The synthesis gas required is suitably generated by gasifying a portion of the coke with O2 and steam. The H2S- containing effluent from the desulphurisation step is pref. used to preheat the coke before the effluent is used in the carbonylation of the metal impurities.

Abstract: Abstract Liquid scintillation counting composition which include certain polyethoxylated poly(oxypropylene) emulsifiers allow stable dispersion of aqueous or other samples merely by shaking.  Preferred are mixtures of such emulsifiers, which give homogeneous, monophasic-appearing dispersion over wide ranges of temperature and aqueous sample content.  Certain of these emulsifiers, without being mixed, are of particular advantage when used in analysis of samples obtained through radioimmunoassay techniques, which are extremely difficult to disperse.  Certain of these emulsifiers, also without being mixed, uniformly give homogeneous, monophasic appearing aque-ous counting samples over much wider ranges of aqueous sample content and temperature than prior sample emulsifiers.

Abstract: LASER LAND-SURVEYING APPARATUS WITH DIGITAL DISPLAY               ABSTRACT OF THE DISCLOSURE         A land-surveying apparatus for use with a laser beam source to obtain grade and range distances has a grade pole with a laser beam detection unit slidably mounted thereon, electrical measuring means being connected between the grade pole and the detection unit to generate an electrical grade signal representa-tive of the grade distance between a detector using an array of phototransistors and the base of the grade pole.  A digital display unit receives the grade signal, processes it, and digitally, visibly displays the information contained in the signal.  Electrical grade calculating circuitry is provided to process first and second grade signals containing the elevation of the upper and lower edges of the laser beam relative to the base of the pole and arithmetically process the signals to obtain the elevation of the laser beam center which is then displayed as the grade distance.  Electrical range calculating circuitry is provided to selectively use information contained in the laser beam and generate a range output signal representing the range distance between the laser beam detector and the laser source, the range calculating circuitry delivering the range output signal to the digital display unit where the range distance is visibly, digitally displayed to the operator   The digital display unit is preferably housed in a control console which is pivotally mounted to the laser beam detection unit and also detachable from the detection unit to permit an operator to hold the control console, permitting easier reading of the digital display and more convenient operation of the console when the laser beam detection unit is at an inconvenient height on the grade pole.

Abstract: CANADA     "IMPROVEMENTS IN OR RELATING TO TUBE COUPLINGS"     ABSTRACT OF THE DISCLOSURE     A tube coupling comprises a collet with resilient arms arranged to co-operate with a cam surface of a surrounding body or sleeve, the cam surface tapering in the axial direction such that, as a tube in the collet is pulled outwardly, frictional pull between the tube and collet causes the collet to move in a direction to tighten the grip on the tube.  The arms of the collet are spaced apart radially such that, in the absence of any tube, the collet can be withdrawn outwardly from the sleeve or body.  Pushing the collet inwardly into the sleeve or body allows the arms to move radially outwardly and the tube can then be withdrawn.   The collet has a flange or the like extending radially outside the sleeve or body and a spring clip is provided between this flange and the sleeve or body to lock the coupling against release of the tube.   By using such a clip holding the collet outwardly from the body the arms of the collet are retained in a position gripping the tube;  the clip prevents the collet from being pushed inwardly to release the tube.

Abstract: ABSTRACT OF THE DISCLOSURE    The present invention discloses an ignition system for internal combustion engines.  The ignition system is particularly applicable to such engines including a magneto.    The ignition system includes a semi-conductor ignition circuit in which a first transistor has its collector-emitter conduction path connected in series with the primary winding of an ignition coil assembly.  A resistor is connected between base and collector of the first transistor to permit it to conduct.  A control circuit connected between the base of the first transistor and the primary winding, turns the first transistor off when it is desired to interrupt the primary winding current.   The ignition system also includes a magneto ignition coil assembly which has a low inductance primary winding having a relatively low number of turns.  The coil assemblies of the present invention are generally unsuitable for use with conventional mechanical breaker points.

Abstract: ABSTRACT OF THE DISCLOSURE          Coal is preheated and contacted with 0.5 to 3 percent by weight of coal tar, preferably bituminous coal tar.  The thus-treated coal is admitted into a coke oven through the ceil-ing of the latter.  The coal is poured into the coke oven, rather than being blown in, and is permitted to descend into the coke oven under the influence of gravity.  Preferably, the coal is poured into the coke oven through at least two or three openings in the ceiling thereof.  The coal tar serves to bind finely div-ided coal particles to the coarser particles and, in this manner, the development of dust during the introduction of the coal into the coke oven is restricted and, concomitantly, the danger of ig-nition or explosion is reduced.  The pouring of the coal into the coke oven helps to further reduce the danger of explosion.  This may be explained in that a conical pile of coal is formed in the chamber below the openings in the ceiling so that coal introduced into the coke oven gradually travels towards the hot walls of the oven along the pile.  By virtue of this, a precipitous heat-ing of the freshly introduced coal particles is avoided and the danger of explosion accordingly reduced.  The pouring of the coal into the coke oven also reduces the danger of explosion in that the gas current used when blowing coal into a coke oven is elimin-ated.  Such a gas current can entrain fine coal particles and there-by result in the development of dust which, in turn, can lead to explosions.

Abstract: TITLE            SONIC MAGNETIC DOMAIN SENSOR              INVENTORS     Witold Kinsner Edward Della Torre ABSTRACT OF THE DISCLOSURE         This bubble domain sensor is capable of sensing the presence or absence of a bubble at a predetermined location within bubble supporting material regardless of whether the bubble is stationary or moving through that location.  A magnetostrictive material layer, such as a thin film having an area approximately equal to the area of a bubble domain, is positioned with respect to the bubble material such that it is magnetically influenced by the closure field of a bubble at the predetermined location.  A conductor,  such as a strip conductor, is positioned in contact with the magnetostrictive material.  A sonic device launches sonic wave pulses which pass in the vicinity of the magnetostrictive material layer.          The sonic wave pulse stresses the magnetostrictive material, and when the magnetostrictive material is magnetically influenced by a bubble, the stress changes or rotates its magnetization thereby inducing an electric signal in the conductor.  When a bubble is not near the mangetostrictive material, no signal will be produced.  The sonic wave pulse may be launched as either a surface wave on, or a bulk wave in the bubble supporting material, or it may be launched in a material substrate, capable of supporting acoustic waves, which is in contact with the magnetostrictive material.  The shape of the magnetostrictive thin film element may have different geometrics, including long strips.
