In an electro-chemical cell for measuring the oxygen content of a gaseous environment subject to pressure fluctuations, the electrolyte is maintained under pressure. As shown in Fig.2, a spring 31 acts on a flexible diaphragm 29 to pressurize the electrolyte, which is a 24% aqueous solution of KOH. The cell has four electrodes: a measuring electrode 35 of Au or Ag surrounded by a tubular guard electrode 33 also of Au or Ag, a porous sintered Pb or Cd reference electrode 24, and a regeneration electrode 28 of Pt, Au or Ag wire. The reference electrode effectively divides the interior of the cell into two parts 22, 23 interconnected through the porosity of the electrode. A diffusion membrane (37), through which oxygen can enter the cell, is sandwiched between an electrolyte-absorbent spacing disc (36) and a film 38 of absorbent material in contact with a circular channel 39 from which water under pressure penetrates the film 38 to reduce evaporation of the electrolyte. A gasket 40 is provided. Spacing disc (36) may be omitted to reduce reaction time. In an alternative embodiment, described with reference to Fig. 1 (not shown), a piston (73) replaces the diaphragm 29 of Fig. 3 and the electrodes comprise a stack of foraminous discs inter-spaced by electrolyte-absorbent material, the order of the electrodes going from the diffusion membrane (4) to the piston (73) being: measuring electrode (6), guard electrode (8), reference electrode (10), and regeneration electrode (12).

Abstract: 540,632. Dynamo-electric braking. BRITISH THOMSON-HOUSTON CO., Ltd., BENNS, H. V., and GREGORY, J. P. Aug. 2, 1940, No. 12503. [Class 38 (iii)] In a motor control system employing reversecurrent braking wherein the reverse current circuit is opened, when the motor reaches a low speed, under the control of a relay subject to the voltage across the secondary or to the current in the primary or secondary of the motor as described in Specifications 522,632 and. 540,633. A pilot contactor P1 is provided: energised when the running contactor 1 is closed so as to prepare a circuit for energising the coil 2 of the reverse current braking contactor. By these means it is ensured that power for reverse current braking cannot be applied except after disconnection of the circuit and application of power for forward running. The invention is applicable both to motors which normally run in one direction only and to those which are arranged to run in either direction. In the second case duplicate pilot relays are used. As shown in Fig. 1, the contactor P1 is controlled by a differential plugging relay: with windings P2b and P2a carrying rectified currents proportional to the voltages across the stator and rotor respectively as in Specification 522,632. When, with the reverse current on the motor the plugging relay opens at low speed of the motor, due to the small voltage across the slip rings, contacts P2b are opened thereby de-energising the braking contactor to disconnect the motor from the supply. Reverse current can only be again applied after the motor has been started in the forward direction by operation of the start button S and closure of contactor P1.

Abstract: 1,097,801. Hydraulic apparatus incorporating reciprocating pumps. SHAFER VALVE CO. March 24, 1966 [Oct. 23, 1965], No. 12996/66. Headings F1A and F1P. Hydraulic apparatus for actuating a device such as a rotary vane hydraulic motor 11 controlling a pipeline valve, comprises a manual double piston pump assembly 25 arranged so that while one piston pumps liquid to the motor the other piston receives liquid discharged from the motor, a manually operable spool valve 75 being provided for determining the direction of actuation of the motor 11. The pump, Fig. 6, comprises a block 105 provided with cylinders 80, 82 having pistons 86, 88 reciprocable therein by oscillating a yoke 89. Mounted on the block 105 is a manifold block 24 having passages 69, 70 each acting alternatively as an inlet or exhaust passage for the motor 11 depending on the position of the spool valve 75. Normally the spool valve 75 is urged by springs 76, 78 to a position in which the passages 69, 70 are closed. When the spool valve 75 is displaced to the right liquid is pumped by piston 88 past a non-return valve 81 into the passage 69, and liquid returning through the passage 70 flows through a T-conduit 83 to the cylinder 80 from which it is forced during the next stroke of the piston 86 past a non-return valve 79 and through a passage 74 to the passage 69. The motor 11 is also operable by a power driven reversible gear pump 20 arranged to supply fluid to a motor port 33 or a motor port 38 depending on the direction of rotation of the motor required. Assuming the pump delivers to an outlet 58, this causes pressurization of a chamber 50 whereby a slide valve 45 is moved from its normal closed position to a position in which a groove 52 on the valve 45 interconnects grooves 48, 51. As the pressure in the chamber 50 increases the flow from the passage 58 is admitted to the motor port 33 through a restriction 36 adjustable to control the motor speed. Fluid discharged from the motor flows through the grooves 48, 51, 52 and a passage 65 to a filter 63 connected to a reservoir and to the inlet 61 of the pump. The inlet 61 and outlet 58 are reversed for operation of the motor in the opposite direction. A permanent magnet (not shown), movable with the motor, is arranged to operate magnetic proximity switches to provide an indication of the motor's position and thus also of the pipeline valve controlled thereby.

Title: Improvements relating to control arrangements for gas turbine-driven blast furnace air blower plant
Inventor: GREY JOHN CONSTANTINE
IPC: F02C3/20
Filed: 1951-06-01
Abstract: 755,922. Gas turbine plant; axial flow compressors. POWER JETS (RESEARCH & DEVELOPMENT), Ltd.- May 19, 1952 [June 1, 1951], No. 13113/51. Classes 110(1) and 110(3) [Also in Group XXXV] A gas turbine-driven blast furnace air blower plant comprising air compressing means arranged to provide working fluid for the turbine and also the blast air for the furnace is controlled by means whereby the air delivery pressure of the compressor is varied in accordance with the mass flow of air supplied to the furnace and with a setting of the blast air supply pressure required by the furnace. Air from a compressor CP is heated in a heater AH and then expanded in a turbine MT driving the compressor. The air leaving the turbine MT is heated in a second heater BH and then divided, part passes to a further turbine AT also 'driving the compressor CP and part passes to the blast furnace BF. The heaters AH and BH are controlled by a regulator P in response to the blast air temperature. The gas turbine blower equipment is controlled by a mass flow monitor FM which operates through a servomotor S1 a cam PVC, the follower of which is connected to a differential control C responsive also to the compressor discharge pressure. The control C operates through a second servomotor S2 a turbine exhaust throttle valve T. The cam PVC as shown in Fig. 5, can be moved axially by a rack RA to preselect the desired blower air pressure and can be rotated by the servomotur S1 in response to changes in mass flow of the blast air. The direction of rotation of the cam PVC by the servomotor S1 may be varied. If the control is to maintain substantially constant mass flow, a reduction of flow should move the cam PVC anticlockwise. If substantially constant pressure is required, a reduction of mass flow should cause the cam PVC to move clockwise. The setting of the servomotor S1 may be varied by hand. The cam follower CF varies the loading of a spring in bellows located in the control C, which loading is balanced by the compressor discharge pressure. Any sort of balance in these loadings causes operation of the servomotor S2 controlling the throttle T. In a modification, Fig. 7, the required pressure is pre-set by taking off a potential difference from the potentiometer PR. This voltage is further adjustable by a potentiometer MS dependent upon the mass flow required and then fed through a rheostat MC controlled by the flow monitor FM to one side of a differential relay DR. The other side of the relay is energized from a pressure sensitive supply PJM. Under equilibrium conditions, the relay arm does not make contact with either of the contacts 1 or 2. If, however, the relay is unbalanced the arm makes contact with either 1 or 2 and energizes the control TC and either opens or shuts the throttle T. The change-over switch PVS is used to change over from constant pressure to constant mass flow operation. The throttle T may be arranged at the inlet of the turbine AT.
