摘要： 17,296. Blieden, M., and Davies, J. H. Aug. 8. Gas turbines.-The efficiency of internal-combustion turbines is increased by causing combustion to take place at an approximately-constant pressure higher than that of the atmosphere, and then reducing the products of combustion below that of the atmosphere before entering the turbine. After leaving the turbine, the working fluid is cooled, preferably by water injection, and then the kinetic energy which it still possesses is utilized to raise it again to atmospheric pressure by means of a suitablyshaped nozzle which, together with the inlet nozzle, is made of soapstone. The initial compression of the air and fuel may be effected by any known means, but, if a turbo-compressor be employed, a distinct advantage will be derived by working the compressor on a cycle which is the reverse of that described above. In the Specification, mathematical reasons for working with the above cycle are given. In Fig. 1, A is the combustion chamber and B, C are the air and fuel supplies respectively. The motive fluid passes through the expansion nozzle E to the turbine wheels F, H and then to the compression tube J. The water spray is shown at K and a water jacket at L. The water cooler and compression tube may be omitted, in which case the motive fluid is compressed to atmospheric pressure in the last turbine passages.

摘要： 24,054. Davies, J. L. Nov. 26. Arc lamps, resistances for. A lamp may be hung from a hook l on the central bolt e of a covered resistance. This consists of a helix f, laid helically round several notched porcelain strips a, which are perforated to receive pins projecting from the arms of a spider c, and are held against the top plate b by the bolt e, connecting the plate and spider. A clip i is provided to connect any part of the resistance with a flexible conductor.

摘要： 10,490. Davies, J., and Ryan, T. P. May 21. Indicators, station &c.-Relates to street or station indicators for use in public conveyances. The names of the streets or stations are printed on the curtain 10, which is drawn from the spring roller 6 on to the roller 4, or vice versÔ, according to the direction in which the vehicle is travelling. The curtain passes round guide-rollers 11, 12, and the names are exhibited in succession through the aperture 13 in the casing. The roller 4 is rotated by the pawl 26 and ratchet-wheel 14, to draw up the curtain from the roller 6. In the opposite direction of travel, the roller 4 is rotated in the reverse direction by the pawl 28 and ratchetwheel 16, and the curtain is rewound on the spring roller 6. Both pawls are carried by the armature 25 of the operating-electromagnet 24, and the ratchet-wheels are carried by a sleeve feathered on the shaft 3 of the roller 4. The sleeve is engaged by a forked lever 19, which has an arm 21 in the path of two clips 22 mounted near the ends of the curtain 10. On the operation of the lever 19 by one of the clips, the ratchet-wheels are shifted laterally with respect to their pawls, to reverse the gearing. A bell is rung at each operation of the indicator, the bell hammers being actuated by a tappet-wheel on the shaft 3. A brake shoe 31 on the armature 25 limits the movements of the indicator.
