Title: Improvements in or relating to reforming naphtha
IPC: C10G59/06
Filed: 1957-10-22
Abstract: <PICT:0818836/IV (b)/1> A naphtha is reformed by first distilling to obtain a light naphtha boiling up to about 200 DEG  F. and a heavy naphtha which latter is reformed over a platinum-alumina catalyst and the reformate distilled to obtain a light reformate boiling up to about 200 DEG  F. which is combined with the light naphtha and reformed over an alkalized chromia-alumina catalyst at 0-200 p.s.i.g. in the presence or absence of hydrogen and the reformate so obtained blended with the heavy platinum reformate.  The naphtha is fed into distillation tower 11 from which C4 and lighter hydrocarbons are removed overhead, a C5-C7 fraction having an end point of 200 \sB 15 DEG  F. is removed by line 13, a 200-360 DEG  F. fraction by line 14 and heavier materials as bottoms.  The fraction in line 14 may be desulphurized before reforming; the charge to the reforming stage 16 may contain 5-30 p.p.m. sulphur, 1-10 p.p.m. chloride, 2-20 p.p.m. water and less than 5 p.p.m. nitrogen.  It is reformed over a platinum catalyst in the presence of hydrogen at 100-400 p.s.i.g. and 850-1000 DEG  F. with a space velocity of 0.1-10 vol./vol./hr. and a hydrogen recycle rate of 1000-8000 S.C.F./barrel of hydrogen employing three heater-reactor stages.  The reformate is debutanized and then fractionated in tower 22, the heavier product being removed by line 29 and the C5-200 DEG  F. overhead being recycled by line 28 to join the light naphtha charge in line 13.  This light feed is reformed over an alkalized chromia-alumina catalyst containing for example 18 per cent Cr2O3, 4 per cent K2O, 4 per cent SiO2 and 74 per cent Al2O3.  Conditions employed are 0-200 p.s.i.g., preferably about 25 p.s.i.g., 975-1125 DEG  F. and a space velocity of 0.1-10 vol./vol./hr.  Hydrogen may be recycled if a fluidized catalyst is used.  The reformate is debutanized and led by line 35 to be blended with the heavy platinum reformate in line 29.

Abstract: 769,113. Feeding sheets. EDWARDS, A., PECK, H., and LINOTYPE & MACHINERY, Ltd. Oct 31, 1955 [Nov. 16, 1954], No. 33117/54. Class 100(1) In sheet-feeding apparatus for a printing press comprising a swinging gripper system for transferring sheets from a feedboard to a cylinder, front register stops are incorporated which can be adjusted whilst the system is in motion by manual control means bearing on the periphery of the rocker shaft on which the gripper system rocks. !Brackets 12, fixed on a tubular rocker shaft 11, carry two crossbars 14, 15, the bar 14 being rockable and carrying the usual gripper fingers 16 for gripping sheets against feet on brackets 18 (not shown) clamped on the bar 15. Also clamped on the bar 15 are several brackets 19, each of which is recessed to accommodate a piston 24 and compression spring 26, and a rod 23, secured to the piston, carries at one end a front register stop 20 and at the other end is connected to one end 27 of bell-crank lever pivoted to the bracket 19. The other end 30 of the lever is connected to a control rod 31 extending diametrically through the rocker shaft 11. the rod being screw-threaded to receive a knurled nut 32. The rod 31 is spring-loaded by means 34, 35 to prevent accidental rotation thereof. Turning of the nut 32 in one direction or the other moves the register stop 20 relatively to the bracket 19 and therefore advances on retards the final sheet register produced by the stop. The oscillatory travel of the nut 32 is comparatively small, and adjustment of the stop 20 can therefore be effected without stopping the press.

Abstract: 307,810. Woodall-Duckham (1920), Ltd., and Duckham, A. M. Dec. 8, 1927. Pneumatic separating. - In pneumatic separating apparatus of the type in which the lighter materials are floated above the heavier, and in which expansion chambers are provided for collecting the dust carried away by the air current the duct leading from the dust-collecting chamber back to the fan is made collapsable for that part of its length contained inside the dust chamber, so that when it is necessary to effect repairs to the return air duct or for some other reason put it out of action, the air in the dust chamber mav have freer direct access to the, atmosphere. In the construction shown, the air-return duct q has the part l inside the dust chamber in the form of a box with the top n and bottom m in the form of flaps hinged to the sides l<0> and adapted to be adjusted by chains &c. either separately or simultaneously. In normal working, the bottom flaps are closed and the top open, the degree of closure being adjusted, to requirements. When it is desired to put the return duct out of action, the flaps are opened so as to offer the least resistance to the discharge of the air through the top of the chamber to the atmosphere. Preferably, the bottom flaps m have staggered baffles t to facilitate the deposit of dust entrained in the air entering the duct in the normal operation of the machine. This dust is discharged periodically into the dust pockets e, the baffles g in the dust chamber being utilized as guides. The fan housing may have adjustable louvres r at the end of the air duct q and a separate inlet s to take air from the atmosphere.

Abstract: 912,539. Radar. ELECTRIC & MUSICAL INDUSTRIES Ltd. Oct. 20, 1958 [Oct. 24, 1957], No. 33307/57. Class 40 (7). A radar display system has provision for producing bearing and position markers, which may be offset from the origin of the radar display, between and/or in place of some of the normal radar screen scans. The positions and bearings of the various markers provided by the invention are determined by potentials applied to the input terminals 4 to 9 in block 1, Fig. 2a, of which 4 to 6 are concerned with position or bearing markers of different shapes having, as origin, the origin of the radar display, terminal 7 with a pointer position marker and terminals 8 and 9 with off-set markers. Terminal 10 receives the normal radar deflection trigger pulse. In operation, the various marker potentials, selectively supplied to the input terminals at the will of an operator, are continuously and cyclically fed to position and/or bearing bus-bars S and T, respectively, under the control of switches 32 to 37 operated by pulses derived under the control of a timing waveform via a counting circuit 17 (Fig. 2a) producing pulses P1 to P9 which are supplied in various combinations, determined by the various relay contacts shown, to " and " gates 23 to 28 (Fig. 2b) which have as second inputs, a pulse waveform derived from the outputs E, F of summing amplifiers 15, 16 (Fig. 2b) concerned respectively with bearing and position (to which the pulses P1 to P9 are also supplied in various combinations), the pulse outputs a to c and e to g of the gates 23-28 operating the switches 32-37. The apparatus shown, which is concerned with the Y co-ordinate of the display is duplicated for the X coordinate of the display and the two sets of pulses on duplicate bus-bars S and T are fed to individual integrating circuits which produce the actual deflection waveforms for the display tube or tubes. The radar video signals and various " bright-up " pulses for the markers are fed to the modulator electrode of the display tube and to produce displays in different scales the integrating circuits are provided with means for varying the time constants of such circuits (Fig. 2c, not shown). The functions of the various symbolic devices employed in the drawings is shown in Fig. 1 and the complete operation of the invention is described with additional reference to various waveforms derived from a basic timing waveform (Figs. 3a to 3c, not shown).

Abstract: 510,785. Indicating-apparatus; weighing apparatus. AVERY, Ltd. W. & T., and TIMSON, W. Dec. 4, 1937, Nos. 33581/37 and 18731/38. [Class 106 (iv)] [Also in Group XVIII] An indicating mechanism incorporating a light projecting system which may be associated with weighing, measuring or other apparatus embodying basic unit indicia (such as weight or volume) and correlated unit indicia (such as price values or computations) is characterised by a stationary light projecting system and a traversable light projecting system, the systems projecting the indicia on to a screen in juxtaposition and in proximity to a clear numerical indication of the basic price of the commodity. As shown in connection with an automatic weighing apparatus wherein the scale plate 4 is supported on a system of levers connected to pendulous resistants 22, 23, one resistant 22, actuates, by means of a ribbon 24, a shaft 26 carrying - a transparent disc 28. The transparent disc bears concentric rings of graduations the outer ring representing weights and the remaining rings representing price computations formed by the products of weight and basic price. A screened lens system 37 and lamp 33 are arranged to project an enlarged image of the price computation on to a fixed screen 29 preferably of satinised aluminium. The lens system and lamp are mounted on a carriage 34 movable by means of a handoperated shaft 45 so as to adjust the optical system radially of the transparent disc according to the basic price of the commodity. To enable the correct setting to be effected, the shaft 45 is geared to a basic price indication 49 viewed through a window 55. A spring plunger engaging holes 47a ensures accurate setting. The weight graduations on the transparent disc 28 are projected on to the screen 29 by a second but fixed optical system located parallel to the system 37. A pointer 28c on the transparent disc enables the zero position of the apparatus to be checked. Instead of indicating price computations, other computations may be indicated, such as weight increment multiples of the minor weighing range of the apparatus resulting from the addition of major weights.

Abstract: 867,436. Glass feeder shear mechanisms. CORNING GLASS WORKS. Oct. 6, 1959 [Oct. 8, 1958], No. 33869/59. Class 56. Glass feeder shear mechanism comprises fluid operated activating means therefor continuously supplied with fluid at a pressure tending to activate the shear mechanism from an open position to a closed position, other fluid operated means to actuate the mechanism in the reverse direction periodically activated and having means activated on its arrival at one of its positions to disable it. Shear arms 11, 12, carrying blades 17, 18, are pivoted about vertical pins 13, 14 and have interengaging gears 15, 16. The arms 11, 12 are closed by a pneumatic cylinder 25 continuously supplied with fluid through a valve 27 in line 26<SP>1</SP> from a surge chamber 28 in air supply line 26. The arms 11, 12 are opened by a hydraulic cylinder 20, linked thereto by an operating lever 21 and link 19, alternately connected with a fluid supply line 34 and return line 36 through a pneumatically operable slide valve 22 thereby alternately opening the shear arms and allowing them to be closed by cylinder 25. To permit the opening operation by cylinder 20, the movement of the slide 32 of valve 22, to the position shown, is controlled by a pilot valve 31 operated by lever 21 at the instant the shear blades 17, 18 arrive at their closed or near closed, position. A pilot valve 40, operable by a timing cam 50, controls the reverse movement of slide 32 thereby disconnecting the cylinder 20 from supply line 34 and connecting it to the return line 36. Throttle valves 33, 35 in lines 34, 36 may be used to modify the fluid flow therethrough to independently control the rate of closing or opening movements of the shear arms 11, 12. Valve 40 connects air supply line 26<SP>1</SP> to line 23 and valve 22 and valve 31 connects line 126 from line 26<SP>1</SP> to line 55 and the opposite end of valve 22.

Abstract: 936,700. Electric selective signalling systems. BENDIX CORPORATION. Sept. 21, 1961 [Sept. 30, 1960], No. 33909/61. Class 40 (1). The apparatus provides means for amplitude modulating at least one carrier frequency in accordance with two independently variable inputs. The variable inputs Ex, Ey are fed to units 10, 15 which each give a signal on one of three leads Vx, Vy dependent upon the range of magnitude within which the respective inputs fall. An arrangement of gates 20, Figs. 3. and 4 (neither shown), gives an output signal on one of nine lines V21-V29, the line selected depending upon the two leads Vx VY on which there is a signal. Lines V21-29 act as gating inputs to at least one attenuator unit 30 which is also fed with a carrier frequency. The unit 30 contains nine attenuating circuits which are selectively enabled by the signals on lines V21-V29. The degree of attenuation is different in each circuit according to the cross correlation function of Ex and Ey so that the amplitude of the carrier is indicative of the particular combination of inputs Ex, Ey.
