Title: Production of catalytically cracked gasoline
IPC: C10G11/00
Filed: 1945-11-26
Abstract: <PICT:0602780/III/1> In a process in which hydrocarbon oil is cracked in the presence of clay-type catalysts with a view to producing mainly products boiling in the gasoline range and gaseous hydrocarbons, the cracked material is cooled to condense condensible products, and the gaseous products are separated and purified by subjection to washing with water, while compressed to at least 3 atms.  The purified compressed gas is then treated with the gasoline condensate to absorb the C3 and C4 hydrocarbons. Fouling of the absorption apparatus is eliminated by this process. In a preferred form, the vapours are condensed in contact with water and the dilute aqueous ammonia solution obtained is used for washing the compressed gaseous hydrocarbons.  Cracked vapours from a cracking unit 1 are passed to a tower 3 where heavy oils are separated and taken off through a stripper 5.  The vapours pass through line 7, are mixed with water, fed through line 8, and then pass through a cooler 9 to a separator 11 where the products separate into a lower aqueous layer, an upper hydrocarbon layer and gases, the latter being drawn off through line 14.  These gases are compressed in a compressor 16 and pass to a tower 18, where they are washed with the ammoniacal liquor removed from separator 11 and tank 13.  The washed gases are passed through line 22 to an absorption tower 23, where they are partly absorbed by the gasoline layer from separator 11 which is fed through line 15.  The liquid hydrocarbons drawn-off through line 26 are debutanized in a separate column.ALSO:<PICT:0602780/IV(b)/1> In a process in which hydrocarbon oil is cracked in the presence of clay-type catalysts with a view to producing mainly products boiling in the gasoline range and gaseous hydrocarbons, the cracked vapours are cooled to condense condensible products and the gaseous products are separated and purified by subjection to washing with water while compressed to at least 3 atoms.

Title: Improvements in measuring gas temperatures
Inventor: MARSDON JOHN RICHARD
IPC: G01K13/02
Filed: 1952-12-16
Abstract: 734,702. Thermometers. ROLLS-ROYCE, Ltd. Dec. 16, 1953 [Dec. 16, 1952], No. 31915/52. Class 97 (3). [Also in Groups XXXVI and XXXVTII] The mean temperature of a moving stream of gas passing through a duct 10 is measured by a thermocouple or other temperature-sensitive element 15a situated in a tube or mixing chamber 13 which projects into the gas stream. The tube has a number of openings 19 situated at different levels so that samples of the gas from different parts of the stream pass into the tube and become mixed. The mixture leaves by an opening 20 near the thermocouple 15a. The opening 20 may be situated at the lower end of the tube or outside the duct 10 in which case it may lead directly into the atmosphere or to an apparatus for maintaining a low pressure at the opening to cause the gas in the tube 13 to flow at a predetermined rate over the thermocouple 15a irrespective of the rate of flow of the gas in the duct' 10. In a modification the tube 13 is divided by a vertical partition to provide a longer path for the gas mixture. Fig. 5 shows a further modification in which an outer perforated tube 17b encloses a tube 17a having an opening 20 at its lower end and enclosing the thermocouple 15a. The mixing chamber may be housed in a blade of a rotating turbine disc or as shown in Fig. 6, in a stationary nozzle guide vane 28 of an internal combustion engine which is formed with an axial bore 32 containing the thermocouple 33 and with holes 36 along the leading edge of the blade. Mixed gases in the bore 32 pass over the thermocouple and back into the main stream through passages 37 in the vane. When the mixing chamber is formed in a rotating blade the cable of the thermocouple passes through a bore in the blade root and is connected to sliprings.

Abstract: 1469511 Axial-flow compressors; gas turbine engines LUCAS INDUSTRIES Ltd 26 June 1974 [5 July 1973] 32090/73 Headings F1C and F1G [Also in Division G3] A fluid-pressure operated device for operating the compressor inlet guide vanes 11 of a gas  turbine engine 12, comprises a body 15, a piston 10 movable in the body in response to a servo pressure signal P s , first and second levers 16, 21, pivotally mounted in the body, means 14, 19, for urging the lever into engagement with a transmission means 22, a valve 35 responsive to the position of lever 21 to provide the signal P s , and means 28, 25, responsive to movement of piston 10 to vary the position of transmission means 22 relative to axes 17, 20 of the levers. Piston 10 is connected to vanes 11 by suitable linkage and is biased in a direction to open the vanes by a hydraulic pressure HP. Pressures P1, P3, are provided by the inlet and discharge pressure respectively, of the compressor. Member 14 is a diaphragm, and lever 21 is urged to the left Fig. 2, by a spring 33 and also by a pivotable lever 19 connected to an evacuated bellows 18 subjected externally to pressure P1. Lever 28 of adjustable length carries a roller 30, which is urged into contact with a conical recess 31 in piston 10 by a torsion spring 27 carried by a lever 25 connected to the ball transmission means 22. In operation, both ends of spool 35 are supplied with hydraulic pressure HP, and the spool moves to connect passage 32 to HP or LP. If pressure P3 increases, or pressure P1 decreases, pressure Ps falls and vanes 11 are opened, piston 10 moves to the left Fig. 1, so that lever 28 moves clockwise so as to move means 22 closer to lever axes 20, 17. The effect of pressure P1 on levers 21, 16, becomes correspondingly  greater and spool 35 is returned to the Fig. 3 position by lever 34, and vanes remain open. A reduction in pressure P3, or an increase in pressure P 1 similarly causes vanes to close. In a modification, Fig. 4, the second lever 40 is connected directly to spool 42, and movement of transmission means 22 by piston 10 alters the ratio of movement between diaphragm 14 and the end of lever 40 remote from the transmission means. Spool 42 is urged to the right by a spring 43 and by pressure in a line 44 from a fuel pump 45 which also supplies the turbine through a meter 46 which is responsive to pressure P1 to thus control the fuel flow. Spool 42 is urged against spring 43 by pressure in a line 47 from the downstream side of meter 46, and by a spring 48; thus the spool is responsive to the pressure drop across the meter which varies the servo pressure Ps.

Counters actuated by reciprocating mechanism; detent mechanism for; zeorizing- mechanism; transfer mechanism.-Words or folios typed are counter by means of a counter arranged on the typewriter and actuated by a pawl e reciprocated from the spacing-key or a numeral key. The numeral wheels c are geared in the usual manner to transfer pinions g loose on a shaft h. In order to zeroize, the pawl e is disengaged and the shaft h, mounted on spring-controlled bars 1, is thrust to the rear to disengage the transfer pinions from the gear-wheels on the numeral wheels, which thereupon return to zero due to their being eccentrically weighted. To prevent overthrow, the shaft h carries rollers k bearing against the peripheries of the numeral wheels. Either the words or units to be charged are counted upon a decimal system, or else units, folios of 72 units, and multiples of these may be registered.

Abstract: 1,218,022. Micrometer gauges. E. F. PRIETO. July 8, 1968 [July 6, 1967; July 5, 1968], Nos.31141/67 and 32341/68. Heading G1M. Accurately machined blocks 6, see Figs. 1 and 3 of Provisional Specification 31141/67 are rigidly clamped together and supported on a tube 5 by threaded nuts 8, 9, and are provided with ears 7 or stop portions, one to each block displaced angularly with respect to one another to form two rows of stops in order that a finger of a dial micrometer (not shown) forming part of a milling machine arranged parallel to the gauge may be brought into contact by movement of the machine with any one of the stop faces 7a, 7b, 7c thereof. The tube 5 and blocks 6 are rotatable and slidable as a whole over a spacer 12 on ball bearings (not shown) along a shaft 4 supported in end bearings 2, 3 protected by bellows 17, so that the finger can pass between the rows of successively staggered stops 7, and a micrometer 10 may be adjusted so that its spindle 10a abuts the end of the shaft 4 which is provided with a collar 13 abutting the nut 9. Further adjustment of the micrometer 10 may be made to move the blocks 6, tube 5 and shaft 4 together to left or right against or with the thrust of a spring 11. In operation, and if for example the blocks 6 are all 1" thick except for the blocks 6a which are “" thick, and if for example it is desired to move the worktable of the milling machine say precisely 3¢", then the dial micrometer on the machine is so located that it reads zero when its finger is in contact with say face 7b. If now the stops 7 are rotated out of the path of the finger and the micrometer 10 adjusted to displace all the blocks “" to the right of Fig. 1, then it can be arranged that the worktable may be displaced until the finger abuts the stop face 7c, so that if a zero reading is again obtained on the dial micrometer then it will be known that the worktable has moved the thickness of three blocks 6, one block 6a and a ¢" set by the micrometer 10, a total distance of 3¢". Brackets 14 pivotally connected to lugs 16 enable the gauge to be bolted or magnetically mounted on the machine frame. In Fig. 1 of Provisional Specification 32341/68 the shaft 4 is both rotatable and slidable in its bearings and the ears 7 are progressively angularly displaced along the gauge to follow a helical path. The shaft 4, tube 5 and blocks 6 are rotatable as a unit by means of a hand wheel 4a keyed at 4b to the shaft and the wheel is circumferentially marked and provided with a spring- loaded plunger 4d so that any one selected ear 7 may be positioned to act as an abutment to the dial micrometer finger. Other figures of the drawing show an adjustable level base having an upright pillar which may be raised e.g. by a geared handwheel and support the gauge at various latchable heights above the base.
