Title: Improvements in and relating to fluid analysis
IPC: G01N27/416
Filed: 1957-02-12
Abstract: 826,174. Electric tests. UNION CARBIDE CORPORATION. Feb. 12, 1957 [Feb. 13, 1956], No. 4723/57. Class 37. The concentration of a desired constituent of a gas mixture stream is determined by partially immersing an inert rotatable electrode in a body of reagent solution capable of changing in ionic content upon contact with its desired constituent, rotating the partially immersed electrode to form a thin continuous surface film of the reagent solution over the unimmersed surface, passing the sample gas mixture stream in contact with the continuous surface film of reagent solution to effect a change in the ionic content thereof and measuring the potential developed between the rotatable electrode and stationary electrode of the same inert material immersed in the reagent solution. The invention is described with reference to determining the oxygen content of a gas mixture using a reagent solution of ammoniacal ammonium chloride containing cuprous ammonium ions. As shown, Fig. 1, carbon electrode 18 mounted in chamber 16 is rotatable at constant speed by motor 26. The reagent solution enters the lower part of the chamber at 36 and leaves at 38 while the gas under test enters at 40 and leaves at 42. The chamber surrounding the carbon electrode is maintained partially filled with the reagent solution so that the surface of the electrode leaving the solution carries a thin film of cuprous ammonium chloride. Contact between the reagent and the oxygen in the gas under test changes the cuprous ions to cupric. Subsequent rotation of the electrode forms a concentration cell consisting of rotatable electrode 18, fixed electrode 44, also of carbon, the cupric ions carried by the rotatable electrode and the cuprous ions in the reagent solution. The potential developed between the two electrodes is fed by terminal 46 and slip-ring 49 to indicating or recording apparatus 74. The reagent leaving the cell is fed to reservoir 56 where the cupric ions are changed to cuprous by metallic copper 70. The regenerated reagent is again fed to the cell. The Specification refers to the possibility of determining the hydrogen chloride content of a gas mixture using water as the reagent.

Title: Method and means for preventing the escape of smoke gases from furnaces, especially in steam boilers
IPC: F23M11/02
Filed: 1925-02-20
Abstract: 229,693. Roucka, E. Feb. 20, 1924, [Convention date]. Air supply, regulating.-To prevent the escape of smoke and gases from a furnace into the outer air, the air supply is so regulated, by the pressure obtaining in the upper part of the furnace, that the pressure at this point never exceeds the atmospheric pressure at the same level. In the form shown an ash-pit damper 6 is connected by a chain 30 to the pistons 28 of a servo-motor 26 the valve-gear 24 of which is actuated, through the balanced arm 20 and rod 22, by the vertical movement of a bell 18 the interior of which communicates by means of a pipe 14 with the upper part 4 of the furnace. In operation, the damper 6 is wide open when the furnace is working at normal load; any decrease, in the load, i.e. in the flow of gases from the grate 2 due to partially closing the flue damper causes a rise of pressure at the port 4 and when this pressure nearly equals atmospheric pressure the bell 18 is raised by a spring 32, the tension of which is adjustable by means 34, and the piston 28 is operated to throttle the damper 6 and thus reduce the pressure at the part 4. A subsequent increase in the flow of gases from the grate causes the bell 18 and damper 6 to return to normal position. Specification 24755/05 is referred to.

[Class 79 (v).] In variable-speed gearing of the kind described in the parent Specification wherein, to effect speed changes, pairs of constantly meshed wheels such as 3, 4 are moved axially together, by virtue of their having curved or herring-bone teeth, the wheel 3 is connected to the driven shaft 6 through a free-wheel clutch which has positive locking means operating by mechanical, hydraulic, pneumatic, or electric means, the latter under the control of the accelerator pedal in the case of a motor vehicle. The free-wheel clutch 29 may be of the ball or any other type and is locked by means of a sleeve 28 moved to the left relatively to a boss 7 to engage clutching teeth 32, 33, the balls 29 then resting inoperative in a groove in the boss 7. This is effected by sliding a fork 36 along an operating rail 35 which fixedly carries the gear striker fork 34. In the case of direct manual operation, the striking element first depresses a locking ball 37 to release the fork 36 from the rail. For hydraulic or pneumatic operation the boss of the fork 36 is formed as a hollow piston engaging a cylinder surrounding the rail 35, the piston being spring-urged to the free-wheel position. For electric operation, an iron boss of the fork 36 is surrounded by a solenoid energized, on a switch being closed by the accelerator pedal of the vehicle, so as to lock the free-wheel at low engine speeds.

Abstract: 1511443 Steam power plant GOSUDARST N I ENERGETICHE INST IM GM KRZHIZHANOV 9 Feb 1976 04994/76 Heading F1Q A steam power plant comprises a boller II supplied with gaseous fuel from a regasification unit 18, 19 to which liquified fuel gas is fed under some operating conditions from a storage reservoir 16 supplied with liquified fuel gas from a gas liquefication system 15. Steam from the boiler unit II expands through a turbine III and is condensed in a water cooled condenser V. When there is more than sufficient fuel available in main gas pipe-line I to meet the demand by the boiler unit II, valves 10 and 13 are open and valve 14 is closed in response to signals from a control unit 12 and gaseous fuel passes to the liquefaction system 15 from which the resulting liquid fuel is fed to the storage reservoir 16. When the pipe-line I cannot supply enough fuel to meet the demand by the boiler unit, valve 13 is closed and valve 14 is open so that part of the demand is met by fuel flowing direct from the pipe-line I and part by fuel flowing from the reservoir 16 via a pre-heating assembly 18, which may be a heat exchanger with a low boiling point fluid flowing therethrough, for example a condenser in a working fluid circuit with an additional turbine opeating on the vapour of the low boiling point fluid, and heat exchanger 19 for gasification. If no fuel is available from the pipe-line I, the boiler unit is fed entirely from the reservoir 16.
