Title: Fluid-operated stop-gear for boiler pumps and the like
IPC: F22D5/14
Filed: 1920-07-26
Abstract: 173,256. Marks, E. C. R., (Veenschoten, V. V.). July 26, 1920. Addition to 172,355. Stop-gear.-In apparatus normally operated by the difference in pressure between two fluids, as described in the parent Specification, a modified valve is arranged to admit one fluid to both ends of the apparatus when the difference in pressure between the two fluids falls to a predetermined amount. The Figure shows the steam supply valve 12 of a boiler feed-pump operated by a piston 16, the upper end of which is connected to the feed-water pipe by pipes 25, and 19, while the lower end is connected to the steam pipe by pipes 30 and 20. The pipes 25, 19, 30, and 20 are connected to a casing 14 containing a valve 22, the upper surface of which is acted on by the feed-water pressure, while the lower surface is acted on by the steam pressure. In the event of failure of the feed-water pressure, the steam pressure raises the valve 22 and passes to the upper end of the piston 16 while a valve 27 on the spindle of the valve 22 shuts off the steam supply to the lower end of the piston 16 and opens it to exhaust through the pipe 30 and a port 28. In order to regulate the difference of pressure necessary to open the valve 23 the valve spindle may be acted on by a spring below the valve 27 or by a spring 35 above the valve 22, or by both. The tension of both springs can be regulated by means of screws. In order to facilitate the seating of the valves the valve 27 may have lost motion on the spindle. A check-valve and a valve controlled by the level of the water in the boiler are arranged in the feedwater pipe.

Title: Improvements in gas turbine plant
Inventor: SHANNON JAMES FORREST
IPC: F02C3/22
Filed: 1952-09-05
Abstract: 722,230. Gas-turbine plant. METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. Aug. 12, 1953 [Sept. 5, 1952], No. 22424/52. Class 110 (3). In an open-circuit gas-turbine plant of the kind comprising at least one compressor 2 for supplying air to at least one combustion chamber 4 supplying gaseous working fluid to at least one turbine 1, means are provided for diverting air from the combustion chamber or chambers and converting the energy of the diverted air into useful work, whereby during the use of fuel of a lower calorific value than that for which the turbine or turbines is or are designed, air may be diverted to compensate for the additional mass flow of fuel necessary to achieve the desired nozzle temperature. Thus, the total mass flow through the turbines is prevented from exceeding the design value. Liquid fuel is supplied to the combustion chamber by a pump 5 driven by, say, an electric motor 6. Alternatively, gaseous fuel of a lower calorific value, such as blast furnace gas, is supplied by a compressor 12. The air which must then be diverted to compensate for the additional mass flow of fuel is passed through a control valve 9 to an air turbine 11 which drives the compressor 12. The plant may be modified to permit the selective burning of more than two different fuels.

A.; 159, South Street, Middletown, New York, U.S.A.) Aug. 9, 1935, No. 22523. Convention date, Aug. 25, 1934. [Class 37] A loading coil 15 for a phantom circuit comprises a closed core having four winding sections all wound in the same direction, and means compensating shunt capacity unbalance comprising a condenser 16 connected from one conductor of a line pair to ground. A high resistance 17 may also be connected between a line conductor and ground to compensate leakance unbalance. The complete loading unit consists of the loading coils 12, 13 for the side circuits 10, 11 and the phantom loading coil 15. The latter comprises an annular core divided into four quadrants, each carrying an inner and an outer winding, the inner windings being denoted by the references A1A2 ... D1D2 and the outer by A3A4 ... D3D4. The unbalances are determined by means of the cross-talk bridge shown in Fig. 2. The key 22 is first closed, thereby shunting out the windings in each of the four sides of the lines. Testing current is then applied from a generator 18 through the resistance arms shown, and since the series impedance of the windings is shunted out, the indicating circuits 20, 21 show only the effect of shunt unbalances. The circuits 20, 21 are provided with variable condensers which are adjusted to give a minimum indicator reading, the adjustment determining the amount of capacity unbalance to be compensated by the condensers 16. If necessary, the shunt conductances 17 may then be connected and adjusted until the shunt unbalance is reduced practically to zero. The key 22 is now opened, and a test made for the series inductance and resistance unbalance, which are compensated by connecting adjustable inductance and resistance devices in series with the lines. The same method may be employed for testing and adjusting the assembly of loading coil units and stub-cable. Specification 258,232, [Class 37], is referred to.
Patent GB-859736-A (GB)
Title: Improvements in or relating to processes for reducing the gas content of carbon
Inventor: TONGE BRIAN LAWRENCE
IPC: C10L9/00
Filed: 1957-07-16
Abstract: The total gas content of carbon is diminished by heating the carbon in a gaseous reducing atmosphere at 300 DEG C.-700 DEG C. for such a time that the carbon-oxygen complexes present on the carbon surfaces are substantially all reduced, the reduction products being removed from the vicinity of the surface either continuously or in stages, for example by a batch process.  Thus, the carbon may be placed in a reaction space through which the reducing gas flows, the used gas containing the reduction products being vented to the atmosphere, or the gas may be circulated in a closed circuit, and may be replenished in stages, and means may be provided to continuously remove the reduction products from the gas.  For a batchwise removal the carbon may be in a closed chamber, and the gas exchanged when equilibrium has been set up. The length of the treatment is normally at least 50 hours.  The preferred reducing gas is carbon monoxide, but other gases such as hydrogen and methane may be used if the reduction products are not harmful.  When carbon monoxide is employed, the carbon dioxide formed can be continuously removed from the gas with potassium hydroxide.  The progress may be monitored by passing the gas through for example N/10 barium hydroxide, the treatment being considered to be completed when no further evidence of carbon dioxide evolution is obtained.
