Title: Improvements in or relating to the hydroconversion of hydrocarbon liquids
IPC: C10G35/04
Filed: 1962-03-06
Abstract: The hydrocracking of hydrocarbon oils, e.g. boiling above 450 DEG F., is effected by passing with hydrogen through a first tubular reaction zone at a turbulent level of at least 25 at 800-950 DEG F. and not less than 500 p.s.i.g., separating under reaction conditions the liquid material from gaseous and vaporous material, contacting the liquid countercurrently with hydrogen heated to 800-900 DEG F., adding the hydrogen containing vaporous hydrocarbons to the gaseous product from the first stage and passing the mixture through a second tubular reaction zone at a turbulence level of at least 25 at 850-1100 DEG  F. and not less than 500 p.s.i.g.  The combined feed to the second tubular reactor may be passed over a hydrofining catalyst (oxides and/or sulphides of Group 6 and/or 8 metals) at 600-950 DEG F., 500-2000 p.s.i.g. and 0.1-10 vol./vol./hr. either before or after passing through the second tubular reactor.  In the first zone oil boiling above 700 DEG  F. is contacted with 1000-50,000 SCF. of hydrogen per barrel at 500-10,000 p.s.i.g.  The amount of hydrogen added at the second stage is 1000-75,000 SCF. per barrel of original feed.  The turbulence levels (defined as the ratio of average apparent viscosity to kinematic viscosity) in each stage may be 50-1000. The product is separated into hydrogen, which is recycled, other normally gaseous products which are treated to recover olefins, and/or pyrolysed to form olefins or used as a fuel or partially oxidized to form a synthesis gas, and normally liquid products, higher boiling material which is recycled and gasoline range which may be used as a liquid fuel or separated into aromatic hydrocarbons which are recovered and nonaromatics which may also be pyrolysed to form olefins.  Where the oil feed is obtained from a crude petroleum, the lighter straight run materials may also be pyrolysed.  C5 and heavier materials are pyrolysed in the presence of steam at 1100-1900 DEG  F. and 0.75 p.s.i.g. and ligher materials are pyrolysed separately under similar conditions.

Title: Improvements in or relating to liquid fuel injection
Inventor: CAMPBELL JOHN FRANCIS
IPC: F23D11/26
Filed: 1953-03-31
Abstract: 741,838. Fuel injectors. PARKE:R APPLIANCE CO. March 31, 1953, No. 8818/53. Class 7(3) [Also in Group XI] A fuel injection nozzle has an outwardly opening valve 17, a small passage 7 delivering the fuel to the injection orifice 5 at low fuel flows and a larger main flow passage consisting of a number of passages 9 which deliver the bulk of the fuel to the injection orifice at large fuel flows. the valve 17 being connected to a spring-loaded piston 20 which opens the passages 9 as the fuel supply pressure increases. The valve 17 slides in a bore 19 in a sleeve 13 and is adjustably attached to the piston 20 by a rod 23 which is flexible enough to allow for slight lateral misalignment of the axes of the valve and piston. Part of the -fuel supplied through a filter 4 from a fuel supply manifold connected at 2 flows directly through the passage 7 in a sleeve 6 to an annular chamber 14 in the sleeve 13 from which it flows through narrow helical passages 15 to the space 16 adjacent the spraying orifice 5. The remaining fuel is supplied through passages 9 under the control of the piston 20 which has a bevelled end 30 controlling the inlet of the fuel to an annular chamber 12 connected to the passages 9. the other ends of which are connected by tangential swirl passages 10 to the space 16. The small passages 15 cause a rapid initial build-up of pressure in the nozzle which causes the piston 20 to move to the right to open the valve 17 wide, the bevelled part 30 permitting a large variation in fuel supply over a comparatively small range of rise in pressure. The space behind the piston 20 is vented to the combustion space by a passage 24 and bores 26. The conical surface of the valve 17, Fig. 6, comprises a part 38 parallel to the valve seat 37 and a part 39 of greater conical angle which prevents the angle of the conical spray decreasing when the valve is wide open. In a modification the inlet to the passage 7 is also controlled by the piston 20.

Abstract: 874,512. Jet propulsion nozzles. BOEING AIRPLANE CO. March 13, 1959, No. 8833/59. Class 110 (3). A silenced jet-propulsion nozzle comprising a rearwardly directed gas discharge duct having wall portions defining an axially extending interruption in the duct causing total or partial separation of the gas streams and forming a passage for rearward movement of atmospheric air, has bleed ports in the duct upstream of the discharge arranged to discharge engine exhaust gases into the passage to increase the airflow through it. The propulsion nozzle, Fig. 1, comprises an outer shell 18, and a central island 19 and tail cone or plug 22 between which are arranged wedge-shaped flow dividers 26 so as to form branch streams of exhaust gases which are materially separated. Each divider comprises sides 26a, 26b which form a passage for atmospheric air leading from an opening 30 in the shell 18. The air flow in each divider is separated by a plate 32 into two streams, one of which is discharged from the rear edges of the sides 26a, 26b and the other is discharged into the interior of the tubular member 20 through openings 34. Increased air flow through the spaces separating the air streams is obtained by bleed ports 36 which allow some of the exhaust gases to pass into these spaces in a downstream direction. If desired, bleed ports may be provided to increase the flow into member 20. A sound insulating or absorbing shroud 38 surrounds the discharge end of the nozzle shell 18. The shroud 38 is preferably of hollow construction and is packed with a glass fibre bat 46 and its inside wall is provided with perforations 48. A flange 44, and vortex generators or deflectors 49 create turbulence and improve the mixing of the exhaust gases with the atmospheric air. A ring-like spray tube 51 may be provided to inject water into the gas stream. In a modification, Fig. 4, the nozzle shell 50 is of a special corrugated form comprising circumferentially spaced deep and wide corrugations 50a separated by groups of narrower and shallower corrugations 50b. The depth of these corrugations is a maximum at the nozzle exit and progressively decrease towards the nozzle inlet. Air ejector bleed ports 52 are provided, especially in the corrugations 50a to increase the air flow through the corrugations. A sound absorption ejector shroud ring 54 similar to the shroud 38 is also provided. Specification 831,152 is referred to.

Title: Preventing pontefract cakes and other liquorice paste confections from adhering to the instrument with which they are stamped
IPC: A23G3/28
Filed: 1935-03-22
Abstract: 431,043. Moulding confectionery. BURDIN, N. V., 118, Wakefield Road, Pontefract, Yorkshire. March 22, 1935, No. 8972. [Class 87 (ii)] To prevent liquorice paste confections or cakes from adhering to the tool with which they are stamped, use is made of compressed air in conjunction with a stamp B surrounded by a sleeve A, according to either of two methods. As shown in Figs. 3 and 3B, the face of the stamp B is flush with the edge of the sleeve A during the stamping operation. The stamp is then withdrawn into the sleeve and compressed air is supplied to the space therebetween. Finally the sleeve is raised and the compressed air causes the cake to remain on the tray. Alternatively, as shown in Fig. 4, the stamp protrudes from the sleeve during stamping. The stamp is then withdrawn as before and lifts the cake into contact with the sleeve. Finally compressed air is admitted which forces the cake off the sleeve and causes it to drop back on to the tray. The stamp and sleeve may be of any suitable pattern or shape.
