Title: Improvements relating to truss girders of ferro-concrete and to roofs formed of the same
IPC: E01D6/00
Filed: 1937-03-13
Abstract: 495,566. Girders ; roofs. FINSTERWALDER, U. March 13, 1937, No. 7448. Convention date, March 13, 1936. [Class 20 (iv)] A method of producing reinforced-concrete truss girders consists in first casting integrally the compression members a, c of reinforced concrete so as to anchor the iron reinforcements e, h, h<1> of the tension members b, d in position prior to loading of the structure, and in sheathing the said reinforcements with concrete after loading of the structure. The loading of the structure takes place after hardening of the compression members a, c and is effected by removing the shuttering and all scaffolding and other supports, apart from the main end supports of the girder. Some or all of the thin iron rods e constituting the reinforcement for the tension members d are screw-threaded at their ends to permit anchoring them in the nodal points k of the girder by plates f, g. The anchorage of the reinforcing rods h, h<1> of the tension members b is also effected by plates i at the nodal points. The compression members a, c may also be reinforced by thin iron rods. Fig. 4 shows the compression members a, c and nodal points k integrally cast in reinforced concrete, with the reinforcing rods of the tension members b, d anchored therein prior to sheathing in concrete. A roof structure may be formed of a series of parallel girders which are produced as described above and have their upper booms a<1> formed integral with an arched roof covering as shown in Fig. 6 ; the tension members of the girders are sheathed in concrete after removal of the shuttering and scaffold supports of the roof.

Title: Improvements in or relating to process and apparatus for quick separation of fluids and particulate solids
IPC: B04C5/081
Filed: 1955-03-15
Abstract: <PICT:0766860/III/1> In the cracking of a heavy residual petroleum oil to produce a low molecular weight unsaturated hydro-carbons, such as ethylene, a stream of inert solid particles at 1250-1700 DEG F. from a heater 13 (as shown a fluid bed type burner), together with a fine preheated spray of the oil from a pipe 19, is led to a reaction zone 17 comprising a vertical cylindrical tube lined with refractory material.  The converted stream passes through a pipe 21, inclined at 10 degrees-60 degrees with the horizontal, into a cyclone separator 19 (see Group II) to separate the solids from the vapours.  The vapours discharged from the separator through a pipe 31 are quenched by liquid, vapour or solids supplied by a line 37.  The solids discharge pipe 25 has pipes such as 39, 41 which supply steam to strip entrained vapours upwardly from the solids.  Some of the separated solids are returned to the burner by a pipe 43.  In a modification a primary vapour product may be withdrawn from the pipe 21 upstream of the separator.

Title: Improvements in turbo-jet engines
Inventor: DESTIVAL PIERRE
IPC: F02C3/06
Filed: 1951-04-02
Abstract: 714,422. Jet propulsion plant. COMPAGNIE ELECTROMECANIQUE. April 2, 1951, No. 7557/51. Class 110(3) To increase the thrust of a gas turbine jet propulsion engine air is taken from. the outlet of the compressor before the combustion chambers and led to the turbine after the first guide blade set. the temperature of the combustion gases at the inlet to the turbine is increased beyond the limit at which surging normally occurs in the compressor, and exhaust reheat means is put into operation to prevent an increase in the rotational speed of the turbine. In the arrangement shown, Fig. 1, air from an axial flow compressor 1 flows through a combustion chamber 2 to a turbine 3, the exhaust gases of which pass to a propulsion nozzle through a duct 30. When increased thrust is required, air is taken from a chamber 9 located ahead of the combustion chamber and led through ducts 8, 7 to auxiliary nozzles 5 arranged around the normal guide blades 4, the fuel supply to the injectors 36 is increased, and reheat burners in the duct 30 arc put into operation. The air supply to the auxiliary nozzles 5 is regulated by a valve 10 controlled by a power relay 11. If, it is desired to burn more fuel in the duct 30 than is required to control the speed of the turbine 3, additional jets 29 controlled by valves 31 actuated by a power relay 32, may be provided. Flaps 34 actuated by a power relay 33 may also be provided to keep the fairing smooth when the jets 29 are put out of operation. When the temperature of the turbine inlet gases is increased, cooling air may be supplied to the turbine rotor disc and blades through a channel 17 the inlet to which is controlled by a valve 18 controlled by a power relay 19. The blades are hollow and are cooled by air supplied through passages formed in the roots. Cooling air passages are also formed between the outside of the inner ends of the blades and spacers located between the blades. The power relays 11, 19, 32, 33 are operated together by the main engine control lever when additional thrust is required. Cooling air is tapped from an intermediate stage of the compressor and passed through channel 22 to cool the turbine casing at 23. This air then passes through ducts 24 to a passage surrounding, the exhaust duct 30. A mixture of water and alcohol may be injected into the inlet of the compressor or into the combustion chambers to increase the ouput of the engine.

[Also in Group V] Powder metallurgy.-A porous metal mould suitable for moulding pottery and articles such as egg trays made from wood fibre is made by filling a master mould with dry powder of copper, nickel, aluminium or alloys thereof, sintering the powder at 800-900‹ C. in a reducing atmosphere, cooling while still in a protective atmosphere and removing the sintered mass from the master mould. Uniform filling of the master mould may be effected by vibration. The porous mould may be made partly of solid metal to which the porous portion is joined during the sintering or may be wholly of porous metal but of different compositions, for example, the face of bronze and the back of copper. The powder used to form the face of the mould may be finer than that used for the backing and this may be effected by painting the master mould with a thin paste of fine powder and then filling with a coarser powder or by first sintering a layer of fine powder and then adding a backing of coarser powder or thirdly, by vibrating the master mould so that the finer particles of between 200 and 250 mesh penetrate through the mass of the powder of between 30 and 50 mesh to the face. In a specific example, bronze powder containing 10 per cent by weight of tin and consisting substantially of spherical particles was pressed into a master mould by hand and sintered in cracked ammonia for four hours at 800‹ C. After cooling and stripping, the porous mould may be polished and electroplated with chromium as described in Specification 603,762.
