Title: Process for the staged catalytic cracking of hydrocarbon oils using finely divided solid catalyst
IPC: C10G11/18
Filed: 1956-08-13
Abstract: <PICT:0801656/III/1> In a two-stage process for cracking a hydrocarbon oil using finely-divided solid catalyst, wherein hot freshly-regenerated catalyst is used to crack the oil in the first cracking zone A, the partially-spent catalyst withdrawn from A being stripped with a gas such as steam in a stripper B and then passed into the second cracking zone C where it cracks a fraction, heavier than gasoline, separated in a fractionating column D from the products obtained from A, the vapours withdrawn from stripper B are passed through line 9 into the fractionating column E used for separating the products obtained in C.  In the Figure, the vapours from stripper B are first mixed with the cracked products from zone C and then introduced into column E, but it is also possible to introduce these two streams separately into the column at two different points.  Stripper B is preferably of small diameter, and the partially-spent catalyst is carried through it in suspension in the stripping gas; the suspension is then separated by settling or centrifugal action.  The spent catalyst withdrawn from the second cracking zone C is stripped with steam in stripper F, the vapour effluent from which is either passed through line 14 into column E, or it is passed through line 15 for use as the stripping medium in stripper B.  The stripped catalyst withdrawn from stripper F through line 16 is regenerated with air in regenerator G; and the hot regenerated catalyst is passed through line 19 to be mixed with fresh feed.  Gasoline (+ gas) is withdrawn from the system through lines 6 and 10.  The higher-boiling oil withdrawn from column E through line 12 is recycled to cracking zone C.  Specification 784,546 is referred to.

[Also in Division H2] In an A.C. system for supplying loads M which intermittently require high reactive current, e.g. squirrel cage pole-changing motors, the line voltage is kept substantially constant at such times by energy from a capacitor CO which is connected via an inverter W, the firing angle of which is controlled in response to measurements of the line voltage and/or the current from a diesel D driven supply generator G. The inverter may be controlled to maintain a slightly leading power factor to compensate for ohmic voltage drop. The capacitor may be shunted by a battery UB to meet the active part of shock loads and it can also supply all the load for a short time during failure of the main supply. Inverter harmonics are suppressed at the bus-bars by reactors LW and filters F or alternatively load and generator reactors LM, LG are provided. The reactors may be shunted by capacitors.

Abstract: 988,115. Semi-conductor devices. RADIO CORPORATION OF AMERICA. June 25, 1963 [July 31, 1962], No. 25299/63. Heading H1K. At least one major face of a wafer of semiconductor material is coated with silicon oxide upon which a layer of photoresist is deposited and after exposing portions thereof to light the unexposed portions are removed together with the silicon oxide regions thereby exposed and metal film is then deposited over this face of the assembly after which the wafer is treated in an organic solvent which softens the resist and removes the remaining portions thereof together with the corresponding overlying regions of the metal film. In the embodiment a wafer of N-type silicon 10 (Fig. 1a) has a number of P-N junctions 14 formed therein by diffusion of boron into the surface. A further diffusion of arsenic or phosphorus into the P-type regions 13 produces further P-N junctions 16. A coating of silicon oxide 17 is then formed on the semi-conductor surface by heating the wafer in steam, and a layer of photoresist 18 deposited on the coating 17. On top of the photoresist, which may consist of bichromated proteins or of film forming polyesters derived from 2-propenylidene malonic compounds and bifunctional glycols, is placed a glass mask plate 19 having a pattern of darkened areas 20 thereon. Irradiation of the mask by ultra-violet radiation from 3 to 5 minutes followed by a treatment of the coated wafer in an organic solvent such as liquid hydrocarbons, alcohols, or mixtures thereof produces the configuration shown in Fig. 1c. The whole of the exposed top surface of the device is then coated by evaporation with aluminium or a film of metallic alloys before immersion in a solvent which softens the photoresist 18. The remaining portions of the layer 18 are then removed, together with the metal film portions covering these parts of the layer 18. After subdivision the individual elements are finished off in conventional manner.

Title: Process and apparatus for the gasification of ash-containing carbonaceous fuel
Inventor: COCKERHAM ROBERT GEORGE
IPC: C10J1/207
Filed: 1962-07-02
Abstract: <PICT:1047711/C4-C5/1> A process for continuously gasifying a solid particulate ash-containing carbonaceous material, e.g. coal or coke, in a fluidized state, comprises feeding the fuel to, and reacting it with, a reactive gas, e.g. O2 and/or H2 and/or H2O, in a bed of the particulate fuel which consists of a carbonaceous portion and an ash portion, passing the reactive gas upwardly through the bed (at 2) to fluidize the particles, passing a gas, e.g. an inert gas, or preferably part of the reactive gas, upwardly (at 3) through a separating zone below the fluidized bed to fluidize the carbonaceous particles, but not the denser ash particles, and discharging (at 10) ash which falls through the separating zone.  The gas introduced at 3 may be at a temperature below the sintering temperature of the ash to cool the ash in the separating zone, the gas being heated and expanding and increasing in velocity upwardly to a value such that at a point intermediate distributers 2, 3 separation of the ash from the carbonaceous material occurs.  Where the reactive gas is O2 and H2, H2 only is preferably used as the separating gas at 3.  The process may be the gasification of a fuel with steam and oxygen at a temperature between 800 DEG  and 1300 DEG  C. to form a gas containing H2, CO, or the hydrogenation of a fuel (with H2 or H2, CO) at a temperature between 700 DEG  and 1200 DEG  C. and a pressure between 5 and 50 atmos. to form CH4.  In a modification, Fig. 2 (not shown), the bed above distributer 2 is circulated up an internal cylinder coaxial with the reactor 1 and down an annular space between the reactor and the cylinder, to provide a more uniform temperature distribution. A specific example is described in which coal is gasified with steam and oxygen.

Abstract: 1454921 Colour television tube TOKYO SHIBAUBA ELECTRIC CO Ltd 7 June 1974 [13 June 1973] 25443/74 Heading H1D To form accurately the dark lines between red-green-blue phosphor stripes on the screen, in operation bombarded by electrons from inline guns (Fig. 1, not shown) through slotted shadow mask 7, photoresist coated faceplate 2 is exposed through shadow-mask 7 and correction lens 28 to linear light source 21 parallel to the mask-slots and positioned to correspond to the deflection centre of the electrons from each gun in turn, the lens being rotated through 90 degrees between exposures for central and side beams. With filter 29 controlling intensity distribution, lens 28 corrects for electron radial aberrations in all beams and applies required lateral corrections to outer beams, varying in different zones: for the central gun the shift axis is set parallel to the stripes and light source (Fig. 4B, not shown); for the outer guns the lens is rotated 90 degrees in the appropriate direction, the off-set centre of the source being rotated about the central gun axis with the lens while the source is relatively counterrotated to maintain fixed direction and is moved longitudinally to eliminate asymmetry of exposure. The resist of dichromated PVA is developed and the unexposed areas washed off; the entire screen is graphite coated and the remaining PVA with graphite is removed by H 2 O 2 , leaving graphite lines (Figs. 3A-3H, not shown). By three similar but less critical stages preferably in another exposure unit, three sets of phosphor stripes are laid down, slight overlap over the graphite being permissible.

Filed: 1920-09-03
Abstract: 172,396. Igranic Electric Co., Ltd., (Cutler-Hammer Manufacturing Co.). Sept. 3, 1920. Controllers, liquid.-A liquid rheostat applicable as an electric motor controller, of the kind in which the resistance is varied by adjusting the level of an elsotrolyte in relation to electrodes of different lengths, is fitted with a single row of electrodes so arranged and connected to a polyphase circuit as to equalize the resistance between each pair of phases under all working conditions. Fig. 1 shows an arrangement of electrodes d, e, f of three different lengths in a tank 6 and their connection tc the conductors a, b, c of a threephase circuit. This arrangement provides that those electrodes which extend into the electrolyte are connected to the phases in cyclic order and are equally spaced under all working conditions, and, if the two end electrodes are regarded as one, each phase is connected to an equal number of electrodes of one particular length. The lower ends of the electrodes d are tapered and provided with narrow extensions d<1> and the lower ends of the electrodes e, f are tapered to a less degree as shown in Fig. 2. The electrodes are mounted on parallel rods 8, openings 7 in the electrodes fitting on annular flanges 11 of insulating and spacing members 10 threaded on the rods. For varying the level of the electrolyte the lower part of the tank 6 is fitted with a chamber 12 to which air is delivered through a pipe 18 from a continuously-acting pump 17, and the air space at the top of the tank, which is closed by a cover 28. communicates by a pipe 27 with the suction side of the pump and also through valves 20 and 21 with the pipe 18. By opening the valve 20 manually, or by operating the valve 21 automaticallv according to the conditions of the circuit, the level of the electrolyte is controlled. To provide for circulation of the electrolyte, holes 31 through which air bubbles escape are provided at the junction of the horizontal and vertical walls 14, 15 of the chamber 12. Fig. 1 shows the application of the rheostat to the control of a three-phase induction motor 32 supplied with primary current from lines L<1>, L<2>, L<3> and coupled to a generator 33 and a fly-wheel. The controlling valve 21, which is normally closed, is opened by closing the circuit of a winding 22 by a polyphase relay 34, normally open, of which the windings 35 are connected to a transformer 36 arranged in connection with the primary supply circuit. An increase of the load on the motor, resulting in a rise of current in the primary circuit, thus effects an opening of the valve 21 to increase the resistance of the rheostat.
