Title: Process for producing carbides of tungsten and/or of molybdenum and their sintered alloys
IPC: C22C1/05
Filed: 1946-08-29
Abstract: A process for preparing sintered alloys of carbides of tungsten and/or molybdenum consists in preparing pulverulent nitride of tungsten and/or molybdenum, carburising the nitride with release of nitrogen, adding a powdered metal or alloy to serve as a binder, and sintering.  The nitride may be prepared by treating pulverized oxide of tungsten and/or molybdenum at a temperature between 450 DEG  and 800 DEG C with a current of anhydrous ammonia.  The carburisation may be effected by treating the nitride, mixed with the requisite quantity of finely-divided pure carbon, at 1200 DEG -1500 DEG C in a current of dry hydrogen or other reducing atmosphere, in a neutral atmosphere, or in vacuo.  The binding metal or alloy, e.g., cobalt or cobalt-iron, may be added in the metallic form, or in the form of oxide which is reduced during the treatment with ammonia.

Abstract: 713,863. Jet propulsion plant. ZBOROWSKI, H. P. G. A. R., VON. Nov. 12, 1951 [Nov. 13, 1950] No. 26398/51. Classes 110(1) and 110(3) A ram jet comprising a combustion chamber defined by an enclosure which is extended forwardly to form a passage for the supply of combustion air is supplied with fuel through the hollow blades having conduits therein m communirotatable about an axis parallel to the direction of flow and located in the air inlet passage, the hollow blades having conduits therein in communication with the fuel tank which deliver to orifices discharging into the passage over the length of the blades. The ram jet shown, Fig. 1 comprises a streamlined body 1 surrounded by a casing 2 which terminates in a jet nozzle 2a. Fuel is fed from a tank 5, which may be housed in the body 1 as shown, or in the body edge of the casing 2a or in the annular supporting wing 3, to the ram jet through one or more windmills 6 driven by the air stream which act as pumps. The hollow hub 9. Fig. 6, of the windmill rotates on ball bearings about the end of the suction pipe 10 which is shaped so that the action of gravity causes the inlet to be located in the lower part of the tank 5. The fuel passes through the hub 9 and conduits 8 to the outlet passages 7 which may open into the leading or trailing edge portions of the blades 6. The passages 7 may be provided with calibrated jets 7a and are preferably arranged parallel to the chords of the blade profiles. The passages may be arranged at different radial distances from the axis on the different blades, but the differences between these radial distances should be constant. The radial distance between two consecutive passages may vary between two to ten centimetres according to the number of blades of the windmill. If desired, these passages may be grouped together in a portion of the blade so as to obtain a local concentration of fuel. The blades 6 are preferably symmetrical about the chord. The rate of fuel supply may be controlled by varying the speed of rotation of the windmill or by cutting out some of the passages 7. The speed of the windmill may be controlled by varying the pitch of the blades 6 or by varying the area of the propulsion nozzle. The passages 7 may be cut out by a manually operated valve or by automatic means as shown in Fig. 8. A slide valve 12 loaded by a spring 15 is arranged so that when a given rotational speed is exceeded, the spring 15 yields and the valve 12 stops off one or more of the passages 7. The valve 12 may be actuated in accordance with variations of the mach number. The windmills may be used to drive an auxiliary electric generator. The application to a supersonic ram jet is also described.
