Title: Improvements in or relating to gas-turbine engines
Inventor: PETRIE JAMES ALEXANDER
IPC: F02C7/232
Filed: 1958-04-02
Abstract: 843,479. Shafts. ROLLS-ROYCE Ltd. April 2, 1958 [April 8, 1957], No. 11446/57. Class 80 (2). [Also in Group XXVI] In a gas turbine engine comprising a turbine rotor and a coaxial driven member, a reduction in the fuel supply to the engine on failure of the driving shaft and consequent relative rotation of the turbine and driven member is effected by the movement, relative to one end of the shaft, of one of a pair of mechanically interconnected members which are mechanically connected to the rotor assembly at opposite ends, respectively, of the shaft. Preferably the fuel supply is cut off by such movement. A rod 22 (Fig. 1) rigidly secured at one end to the turbine rotor 13a extends coaxially through the shaft 14 and has screw-threaded engagement with a sleeve 24 slidably mounted in a bush 25 and rigidly secured to a tube 26 extending through the compressor rotor 10a. The tube 26 is secured to a cross-member 26a having radial fingers 26b which extend through axial slots 10h in the rotor shaft and are secured to the inner race of a thrust bearing 27. The mechanism 22-27 is normally inoperative, but in the event of a failure in the shaft 14 or rotor 10a the turbine rotor overspeeds and the consequent relative rotation of the rod 22 and the sleeve 24 causes the tube 26 and bearing 27 to move axially and actuate a linkage 28-31 which is connected to the outer race of the bearing 27 and which closes a shut-off cock 20 in the fuel pipe 18. Shut-off also occurs in the event of a failure in the turbine supporting bearing 32, when the turbine and the shaft 14, which is splined to the rotor 10a, move rearwardly and pull the rod 22 and sleeve 24 to actuate the linkage. In an alternative embodiment (Fig. 2) a sleeve 73 in screw-threaded engagement with the turbine stub shaft 72 is splined to a rod 75 secured at its other end to the compressor shaft 40b. Fuel supplied by a pump 52 passes to manifolds 56, 57 through pipes 54a, 54b and 55a, 55b, and a shut-off valve 58 normally held open (as shown) by a spring 65. Valve member 59 is linked by a cable 66 and bell-crank 68 to a plunger 69 biased to the right by a spring 71 serving to keep the cable taut. On failure of the driving shaft the sleeve 73 is displaced to the right by the relative rotation of the turbine stub shaft 72 and depresses the plunger which draws the valve member 59 to the shut-off position in which the land 59b closes the delivery pipe 55a and land 59a is between the pipes 54a, 54b, and diverts fuel from the pipe 54a to a return pipe 62. The pipe 54b then communicates through the space 60 and branch 55c with the pipe 55b, and fuel in both pipes drains out through the space 61 and pipe 63. The shut-off is also actuated by the failure of the turbine supporting bearing 50b. This arrangement may also be used in conjunction with the low-pressure stage of an engine having high- and low-pressure turbines mounted on coaxial shafts.

Title: An improved manufacture of hydrocarbons by alkylation
IPC: C07C2/62
Filed: 1940-07-10
Abstract: 553,334. Acyclic hydrocarbons. STANDARD OIL DEVELOPMENT CO. July 10, 1940, No. 11488. Convention date, Dec. 28, 1939. [Class 2 (iii)] In a two-stage alkylation process wherein a sulphuric acid extract of olefins is reacted with at least one paraffin containing at least one tertiary carbon atom under alkylation reaction conditions, there are fed to the extraction zone sulphuric acid of alkylating strength, i.e. of 90-110 per cent. concentration, and a mixture containing mono-olefins, in the proportion of about 0.4 to about 1.25 mols. of acid per mol. of mono-olefins. Advantageously, the extract used for the alkylation contains about 0.77 to about 2.5 mols. of acid per mol. of mono-olefin. In an example, a refinery C  4  cut is fed by a pipe 2, Fig. 1, to the extractor 3 provided with a mechanical stirrer 4 and receiving partially spent alkylation acid through a pipe 27 from a settler 26 associated with the alkylation reactor 16 and fresh acid may be supplied to the pipe 27 through pipes 24 and 28. The resulting mixture passes through a pipe 6 into a settler 7 where it separates into two layers. The upper hydrocarbon layer passes to a fractionating column 9 whence the lower-boiling fraction passes to a second column 37 which separates the normal and iso-butanes, the latter being fed through pipes 15, 14 to the alkylation reactor 16. The upper-boiling fraction from the column 9 may be withdrawn by pipe 11 or cooled and fed through pipes 12, 14 to the reactor 16. The acid-olefin extract from settler 7 is fed through pipes 13, 12, 14 to the reactor 16. The reaction mixture leaving the reactor 16 by a pipe 18 may be recycled therethrough by way of pipes 19, 20 and 21 or 22 or may be fed to the settler 26, from which the upper hydrocarbon layer passes to a fractionating column 32 from which unreacted hydrocarbons pass by a pipe 34 to the pipe 15 and the desired alkylation products are withdrawn through a pipe 35. Arrangements of apparatus are also described wherein a plurality of extractors 3 each with its settler 7 is arranged in series, with or without the interposition of a fractionating column 9 between successive extractors. Specification 530,250 is referred to.

Title: Improvements in means for regulating the idling power of fuel-injection internal combustion engines
IPC: F02D9/00
Filed: 1955-04-22
Abstract: 768,323. Regulating. DAIMLER-BENZ AKT.-GES. April 22, 1955 [April 22, 1954], No. 11704/55. Class 7 (6). In a fuel injection engine having a main air throttle valve 2 and an injection pump 4 controlled by a suction-responsive device 10 connected by a pipe 7 to a tapping point 8 in the induction pipe 1 on the engine side of the throttle valve 2, a device 15 responsive to engine temperature is connected to an auxiliary throttle valve 23 by-passing the main throttle valve 2 and to a throttling device 19 disposed in a subsidiary tapping 12 connecting the main tapping 8 with a port 11 on the upstream side of the main throttle valve 2, the valves 19, 23, being closed at normal engine temperatures but opened when the engine is cold to provide increased power at idling. During normal running, the idling power is determined by the idling position of the main throttle valve 2, the valves 19, 23, being closed. When the engine is cold, however, the device 15 opens the valve 23 to allow extra air to by-pass the valve 2 and simultaneously opens the valve 19 to reduce the suction in the pipe 7 and hence increase the fuel supply to obtain increased power. The upstream end of the by-pass 13 may be open to atmosphere instead of into the induction pipe 1 and the device 15 may be responsive to the temperature of the cooling water, cooling air, or lubricating oil. In a modification, Fig. 2, the valves 19, 23, are replaced by a single slide valve 25 controlling the subsidiary tapping 12 and an auxiliary air passage 13 bypassing the main throttle valve 2.

Abstract: 664,563. Continuous, ingot casting-machines. OSTENDORF, P. May 3, 1949 [May 3, 1948; Jan. 10, 1949], Nos. 11762/49 and 11763/49. Class 83 (i). Casting composite articles; moulds.- A continuous-casting mould, for producing ingots of light or heavy metals, with an outer cooling jacket which engages the mould along vertical sealing surfaces 7 is characterized in that these surfaces are in planes which are the resultants of the expansion of the mould in two directions at right angles. The mould may consist of plates 1, 1<SP>1</SP> welded at 2 and secured to wedge - section guides 6 which engage corresponding guideways 5 of the water jacket 3. The surfaces 7 are in planes which intersect along a vertical axial line. To avoid distortion, supporting bars 18, Fig. 1, may be used. The horizontal sealing surfaces 7<SP>1</SP>, Fig. 6, at the top and bottom of the mould, may also be directed as are the surfaces 7, the four planes P intersecting, in a horizontal line O. The line of intersection need not be through the centre of the mould and may lie on one of the plates so that two of the sealing surfaces also lie in the plate, the other being more steeply inclined. In a modification, the plates 1, are replaced by U-section bars 1<SP>11</SP>, Fig. 2, and the jacket consists of two parts 3 sealed at surfaces 7 with guides 6, and two hollow parts 3<SP>1</SP> which engage the parts 3 along surfaces 7<SP>1</SP>, 7<SP>11</SP> having the same function as the surfaces 7 and set off stepwise at 8. Vertical channels 9 serve to drain off escaping water. For forming plated ingots each plate 1 is secured to two guides 6, Figs. 3, 4, and all extend much above the bars 1<SP>11</SP> to which they are not fixed but are instead fixed to a bottom mould-piece 12 having hydraulic or other means 14 for moving it down during pouring. The faces of the plates 1 may have dovetail grooves 10 near their vertical edges to receive some of the molten metal. The cooling- chambers may be divided up by internal walls or be duplicated. The mould may be used in inclined or horizontal position if a suitable pouring head is provided. The Specification as open to inspection under Sect. 91 states also that the inclination of the surfaces 7, 7<SP>1</SP> should be modified to allow for the fact that the rise in temperature of the guides 6 is not so great as that of the plates 1, 11. This subject-matter does not appear in the Specification as accepted.
