Title: Improvements in or relating to electric signalling or control systems
IPC: G08C19/26
Filed: 1931-11-12
Abstract: 381,376. Automatic regulation. SIEMENS & HALSKE AKT.-GES., Siemensstadt, Berlin. Nov. 12, 1931, No..31398. Convention date, Dec. 18, 1930. [Class 38 (iv).] In a system in which a measuring instrument is adapted for regulating a value, e.g. a load in accordance with the frequency of impulses from a distance, the impulses operate at the receiver a single-pole switch which controls two circuits associated with individual, condensers or a common condenser in such a manner that the apparatus to be controlled is operated by condenser current of frequency double that of the impulse transmission. As shown in Fig. 1, impulses transmitted over the line wires 2 operate relay 1 the armature 1a of which connects the condensers 3, 4 alternately in circuit with the measuring instrument 6 and battery 5. Upon arrival of an impulse, condenser 3 is charged over resistance 8 which short-circuits condenser 4, and upon cessation of the impulse the armature 1a relapses to effect the charging of the condenser 4 over resistance 7. In this manner, the instrument 6 is operated by the charging currents of the condensers 3, 4, the frequency of charging being double that of the impulse transmission and the value of the currents being proportional to the transmission frequency. In the modification shown in Fig. 2, a single condenser 14 is connected alternately to the coils 11b, 11c of a quotient measuring instrument 11, the coil 11a of which is permanently connected across the battery. The arrangement is such that each transmitted impulse and subsequent interval causes the discharge and charge of the condenser through the coils 11c, 11b respectively, the effects through which are in the same direction. In a further modification, a rotary coil instrument having two coils arranged in juxtaposition on the same axis may be used.

Title: Improvements in or relating to closed feedwater supply systems for marine and like boilers
IPC: B01D19/00
Filed: 1948-12-08
Abstract: 654,572. Feedwater supply systems. ARR OWSMITH, G., and HICK, HARGREAVES & CO., Ltd. Dec. 8, 1948, No. 31752. [Class 123(ii)] In a closed feedwater supply system for a marine &c. boiler 6 comprising a condenser 2 associated with, for example, a steam turbine 3 and having an extraction pump 1 which discharges through pipe lines A, B and intermediate condenser 4 of a steam-operated ejector to the feed pump 5 of said boiler, a deaerator 10 is located in a shunt circuit of the pipe line B. The deaerator may be of the directcontact type described in Specification 551,063. As shown, an inlet branch 11 from the pipe B is connected through sluice and automatic valves 12, 13 to the coil &c. of the deaerator condenser 14, the other end of said coil is connected by a pipe 15 to the spray jet pipe or pipes of the deaerator, and deaerated water is withdrawn from the latter by a pump 21 which delivers through a branch 22 controlled by a discharge valve 23, to the pipe B at a point 24 which is nearer the pump 5 than the inlet branch 11. Steam is supplied to the deaerator through a pipe 27 and automatic emergency valve 28, and the condenser 14, which is connected to the lower part of the deaerator by a pipe 18, is vented to atmosphere at 17. The valve 13 is controlled jointly by the pressure in the pipe B, through a line 19, and by the level of water in the deaerator, through a pilot float valve 31 and line 20 respectively, and the valve 28 is controlled by the pressure in the pipe B through a line 30. The deaerator has a capacity such as will meet the maximum demand of the pump 5; when, however, there is a lesser demand the excess discharge from the deaerator will be recirculated though the latter. Moreover, should the pump 21 be shut down or fail, the float valve 31 will be operated to shut the valve 13 to cut-out the deaerator; similarly failure or closing of the pump 1 will effect closure of the valve 13 and also the valve 28. The deaerator may be used when the main power plant is shut down by installing an auxiliary pump 33 between pipes 34, 35, leading from and to a feed tank 9 and the pipe B respectively, and it is preferably provided with a steam branch 38, controlled by a valve 39, leading to low-pressure auxiliary machinery such as evaporators &c. A modified installation with a spray type deaerator, as disclosed in Specification 550,998, is also described. Specifications 531,062 and 561,366 are additionally referred to.

Filed: 1932-11-10
Abstract: 396,972. Electromagnets. KENNEDY, H. E., 105, Tunnel Road, Berkeley, and WALKER, B., 650, Highland Avenue, Piedmont, both in California, U.S.A. Nov. 10, 1932, No. 31842. [Class 35.] An electromagnet 36, controlling the fuelinjection valve 17 of a Diesel engine through an armature 22, is mounted in a housing 19 so as to be pressed by a spring 25 against a supporting-member 24, which rests against the rigid valve casing 11, the movement thus allowed to the magnet 36 and its support 24 within the housing 19 preventing distortion of the housing from affecting the correct relative positions of the magnet and the valve seat. The valve is held closed by a spring 26 arranged between the armature 22 and an adjustable screw 27. The duration of opening of the valve is varied by adjusting a resistance 30 by which the time-lag between the cutting-off of the current and the closing of the valve is varied. The resistance 30 may be rendered ineffective during the energizing of the magnet, by the introduction of a rectifier R between the resistance and earth.
