Title: Improvements in or relating to the sweat-cooling of components, e.g., for gas turbines
Inventor: FOWLER HOWARD STANLEY
IPC: F01D5/18
Filed: 1952-02-11
Abstract: 731,161. Turbine blades. PARSONS & MARINE ENGINEERING TURBINE RESEARCH & DEVELOPMENT ASSOCIATION. Feb. 5, 1953 [Feb. 11, 1952], No. 3563/52. Class 110 (3). [Also in Group XXII] A method of making a gas turbine blade capable of being sweat-cooled comprises coating a solid metal core with low melting- point alloy, die-moulding a porous metal layer around the core, heating to sinter the moulded metal and bond it. to the core and then forming coolant supply passages in the component. Around the solid metal core a of a gas turbine blade is moulded a porous metal powder wall b which is subsequently sintered, the bond between the coating and the core being strengthened by first coating the core with a low melting-point alloy. Supply passages c for the coolant are formed by drilling and are in communication with a common supply chamber at or below the root by way of holes of appropriate sizes whereby the supply to each passage c is throttled to a predetermined amount so that the pressures in the passages are regulated to give the correct flow distribution around the blade. Specification 619,634 is referred to.

Patent GB-765615-A (GB)
Title: Improvements in or relating to fluidized coking process
Inventor: JONES WILLIAM HENRY
IPC: C10G9/32
Filed: 1955-02-08
Abstract: <PICT:0765615/III/1> In a process for converting heavy liquid hydrocarbons into lighter products and coke the liquid hydrocarbons are contacted with hot inert solids, e.g. coke particles, fluidized in a vertically elongated coking zone 10 by being injected from a manifold 1 at a plurality of vertically spaced levels 2, 3 and 4, the feed rate at any level being less than about 5 gallons per minute per square foot of cooking zone cross-section, and the rate of injection in the range of 0.1 to 3 weight per hour per weight of fluidized solids.  The preferred feed rate is between about 0.1 to 1.5 gallons per minute/sq. ft. for cylindrical cooking zones smaller than about 10 feet in diameter, and up to about 3 gallons per minute/sq. ft. for larger coking zones up to about 15 feet in diameter.  The successive feed levels are preferably spaced so that approximately equal volumes of fluidized solids will exist between them and for cylindrical zones a preferred spacement of the levels is 1 to 2 zone diameters.  The hydrocarbon feed is preferably pre-heated to between 400-800 DEG F. and the inert particles mostly have a diameter of about 80 to 300 microns. Product vapours are withdrawn through line 16.  The fluidized bed is maintained at a coking temperature of 800-1200 DEG F., preferably 950 DEG F., where a distillate suitable for catalytic cracking is to be the principal product.  Higher temperatures may be used if ethylene or aromatics are the principal desired products. The pressure at the top of the coking zone may vary between subatmospheric and about 100 p.s.i.g.  Coke particles are withdrawn from the coking zone through line 19 and passed with air to a burner 20 preferably fluidized where it is heated to at least about 100 DEG F. above the temperature of the coking zone.  The thus heated coke is returned to the coking zone through lines 25, 26 and 27 arranged at levels close to the feed levels 2, 3 and 4 respectively.  A portion of the coke is withdrawn through line 29 partly as product coke and partly to pass through a grinder to supply the required amount of seed coke for return to the coking zone.  The coke passed to the coking zone may be activated, e.g. by treatment with superheated steam.  In a modification the coke may be reheated by combustion of an extraneous fuel, e.g. oil or fuel gas.  In another modification the main part of the coking zone has an inverted conical shape so that the velocity of the uprising gases will remain uniform despite the fact that volatization of the hydrocarbon feed creates additional volumes of gases.  As an example the coking of a residual oil may produce about 10-20 weight per cent of coke, 7-12 weight per cent of C3 and lighter gases, about 15-25 volume per cent of a C4/430 gasoline fraction, about 45-64 volume per cent of a gas oil fraction boiling from 430-1015 DEG F., and about 0-25 volume per cent of a residual fraction.

Jib cranes. - In compensating luffing-gear of the kind in which the load rope passes round a pulley C carried by a radius link DC and moving in guides f in the jib, the load rope is led from a drum or guide pulley at E and over pulleys at B, C, and B to the load.

Title: Improvements in the manufacture of nitric acid esters of aliphatic alcohols
IPC: C07C201/02
Filed: 1958-02-06
Abstract: Nitric acid esters of aliphatic alcohols are manufactured by introducing the nitrating acid into an injector under pressure, the alcohol and a non-reactive gas, in an amount from 5 to 30% by volume based on the total volume of liquid supplied to the injector, being drawn simultaneously by suction into the injector under such conditions that, in addition to immediate mixing and conversion of the reaction components substantially completely within the injector, gas dispersion and emulsifying takes place with formation of a stable non-explosive emulsion of the reaction products, which is then rapidly moved through a closed conduit to a separator house remote from the nitrating apparatus where the nitric ester produced is separated from the spent acid in a centrifugal separator.  Cooling may be applied immediately after the emulsion has left the injector. The process is exemplified with reference to the production of nitroglycerine with the use of air as the added gas.  Specification 735,888 is referred to.

The cutting knife 34 is secured to a shaft 38 by a clamp 58 and located by a key 64; and wedge members 47 are provided for adjusting the cutting edge 50 to that of the knife 30. The second knife 36 is secured to a second clamp 80 which may be adjusted angularly about the shaft relative to the clamp 58; adjusting wedges 88 are provided. The web is fed by rollers 12, 14 driven by a motor M via a gear-box 16 which also drives the cutting apparatus; a second identical apparatus 11 is also driven by the gear-box. In operation, the rotary knife 34 first co-operates with the knife 32 to cut out a shape from the edge of the strip. The web continues to move so that the knife 36 cuts a further portion from the web thereby increasing the length of the cut shape by a distance (α), Fig. 3 (not shown). By adjusting the speed of the web feed and the angular spacing between the rotary knives 34, 36, cutouts of different lengths may be obtained. In a modification, the length of the knife 34 can be made shorter and the knife 36 made longer and more than two knives may be angularly spaced around the shaft. Reference has been directed by the Comptroller to Specification 1,345,860.

[Also in Division H2] In an electrically driven pump, the loading of a free tongue 15 of a snap action switch spring 18 is adjustable by a setting member 26 so as to oppose the action of spring-flexed outer arms 20 of the switch spring which are capable of adopting either of two stable positions so that when the mechanical force in the tongue is overcome by a force derived from the reciprocating member of the electric motor the switch is actuated. In the fuel pump 1 shown, energization of the winding 5 causes armature 2 and rod 9 to move a flexible diaphragm 10 against tongue 15. The tongue 15 is deformed so as to cause contact 19 to move away from fixed contact 21. The armature 2 is then returned by the action of spring 8 and the cycle is repeated. By adjusting the screw 26 the rate at which the contacts 19, 21 operate can be varied, so varying the speed of pumping. The ends of the arm 20 are located in notches in a yoke 13. The auxiliary diaphragm 10 prevents fuel from entering the switch. The winding 5 may be formed of a strip conductor insulated with an oxide or paper.
