Abstract: 716,456. Jet propulsion plant; gas turbine plant. SOC. NATIONALE D'ETUDE ET DE CONSTRUCTION DE MOTEURS D'AVIATION. May 26, 1952 [June 20, 1951], No. 13327/52. Class 110(2) [Also in Group XII] A ducted-fan turbo-jet engine comprises at least one pulse jet unit which is disposed in the duct by passing the gas turbine unit and is supplied with at least part of the flowing through said duct. The ducted-fan turbo-jet 'engine, Fig. 1, comprises a single- or multi-stage turbine 8 driving high- and low-pressure compressors 1, 2 respectively and a series of airjacketed. pulsatory combustion chambers 10 which are interconnected by a tube 30 for ignition purposes and terminate in nozzles 13. The air circulating between the combustion chambers is discharged through an annular nozzle 16. The combustion chambers are disposed parallel to the longitudinal axis of the engine or are arranged obliquely thereto along the generatrices of a hyperboloid if they are rectilinear or helically arranged if their axes are curved. The combustion gases entering the turbine are mixed with compressed air taken from the delivery side of the high-pressure compressor. The whole of the air fed to the bypass duct 6 may be passed through the combustion chambers ]0. In a modification, (Fig. not shown), a series of convergent-divergent nozzles 17 are disposed in alignment with and are axially spaced from the members 13 whereby the orifice 16 is dispensed with. In a further modification, Fig. 5, the nozzles 17 are mounted on an annular member 20 for axial adjustment along bearing surfaces 21, 22. When the combustion chambers 10 are operating the nozzles 17 engage the members 13 whereby the compressed air circulating between the combustion chambers 10 is discharged through annular orifices 26, 27 instead of the nozzles 17. The lowpressure compressor may incorporate a device for regulating its intake section.

Title: Universal joints
IPC: F16D3/04
Filed: 1978-09-05
Abstract: In a coupling for transmitting drive from one shaft to a second where there is imperfect alignment the drive is transmitted from a claw 101 on the first shaft to a claw 101 on the second through two systems (primary and secondary) each consisting of a pair of input links 102, 102 & 103, 103, a floating spider 104 & 105, and a pair of output links 102, 102 & 103, 103. Figure 1 shows one half of the coupling, the floating spiders 104 & 105 of that half being bolted at 107 to the floating spiders of the other half, and the four links of each half being mounted by rubber bushes. In the aligned condition, the input links 102, 102 of the primary system are parallel and the output links 103, 103 extend at right angles to the input links, or closely so. In the same condition the input links 103, 103 of the secondary system are parallel to the output links 102, 102 of the primary system and the output links 103, 103 of the secondary system are parallel to the input links 102, 102 of the primary system. The arrangement described has the advantages that it will transmit rotation with almost exactly constant 1: 1 velocity ratio when the first and second shafts are misaligned, and if the masses of the primary and secondary spiders are made equal, the coupling remains in balance in this condition. The primary and secondary systems can also be arranged so that the links of one or other system are in tension in either direction of power flow. Springs may be interposed between the spiders. <IMAGE>

Title: Compensation amplifier
IPC: G01R13/04
Filed: 1978-10-18
Abstract: A pivotable member 4, co- operates with a sensing means 5 for sensing the pivotal position of the member 4, and a drive means for applying to the member 4 a compensating torque in dependence upon the sensing means. The drive means comprises a motor 8 for rotating a shaft 10 which extends substantially parallel to, but not aligned with, the pivotal axis of the pivotable member 4. The shaft 10 has fixed to it one end of a coil spring 11 which coils around the shaft 10 and has an opposite end fixed to the pivotable member 4 to apply the compensating torque to the pivotable member 4 when the shaft 10 is rotated. The disturbing torque may be provided by a measured current in a moving coil movement 1, 2 and thus the rotation of the drive means translated to an indicator or recorder 12 shows the value of the current. <IMAGE>

Patent GB-2031262-A (GB)
Title: Method and apparatus for automatically feeding a plurality of rod machines
IPC: A24C5/39
Filed: 1979-09-21
Abstract: The invention relates to a method of automatically feeding a plurality of rod machines for example cigarette machines, with a filling material, for example tobacco. The individual rod machines are arranged to emit demand signals whereupon tobacco is transferred into conduits leading to the rod machines. The conduits in question are subject to a vacuum and tobacco is then conveyed by suction to the rod machines indicating a requirement. If a first rod machine emits a demand signal before or during a second rod machine feed preceding that of the first rod machine, there is supplied, before the termination of the feed time of the second rod machine, a vacuum to the conduit leading to the first rod machine so that, after the termination of the feed to the second rod machine, the tobacco passes without interruption into the conduit leading to the first rod machine. The invention also extends to an apparatus for automatically feeding a plurality of rod machines in this manner.

Patent GB-2037809-A (GB)
Title: Conversion of Carbonaceous Materials into Fluid Products
IPC: C10L5/06
Filed: 1979-12-04
Abstract: Solid carbonaceous materials and particularly coal are converted to gas hydrocarbon fluids, e.g., gas, by forming an aqueous slurry in which an amalagam of carbonaceous and non- carbonaceous particles are suspended in a suspension liquid such as water. The slurry is mixed together with an agglomerating liquid lyophobic to resuspension liquid and non- carbonaceous particles and lyophilic to carbonaceous particles to form a mixture, and the mixture is agitated to preferentially agglomerate carbonaceous fine particles to form discrete agglomerates having chemical and physical properties which are known and which are substantially uniform and constant. The non-carbonaceous fine particles remain substantially unagglomerated in the slurry and are separated from the discrete agglomerates. The discrete agglomerates or reconstituted particles are then heated to greater than 1500 DEG F and preferably greater than 2000 DEG F in a controlled atmosphere to convert them into a gaseous product. Alternatively, the reconstituted particles or discrete agglomerates are to a temperature of about 750 DEG F to 1000 DEG F under controlled conditions to form a liquid product.
