Abstract: 877,748. Forced-flow steam boilers. SULZER FRERES S. A. July 5, 1960 [July 20, 1959], No. 23507/60. Class 123(2) A forced - flow, once - through steam generator heated by the gaseous coolant of a nuclear reactor comprises heating sections IV disposed in a flow path G for the coolant gas, the inlet and outlet temperature of the latter being maintained substantially constant by increasing or decreasing its flow velocity as the load on the generator varies in response to signals from temperature pick-offs 16, 17. The heating sections to which water is fed by a pump E comprise evaporating sections I, II and superheating sections III .... V, a constant level separator 3 from which water is returned to the feed pump inlet through a line 21, being disposed between sections II and III. The pump speed is controlled in response to water and steam flow measured respectively at 1 and 4 and working medium temperature measured at 2 whilst the final steam temperature is regulated by water injection at 10 in response to temperature measurements taken at the outlet 5 of the superheater section V. To avoid excessive displacement of the transition section consequent on a change from full to partial load which would occur if the sections were arranged in sequence in the flow path and to reduce the quantity of water required to be injected at 10 the final evaporator II is located upstream of the first superheater section III with respect to the flow of heating gas.

Title: Improvements in and relating to tuned circuits
IPC: H03H7/01
Filed: 1930-08-06
Abstract: 360,062. Valve amplifying circuits filter circuits. RADIO FREQUENCY LABORATORIES, Inc., Boonton, New Jersey, U.S.A. Aug. 6, 1930, No. 23545. Convention date, June 13. [Classes 40 (iii) and 40 (v).] Two tuned circuits are coupled through a common reactance at their low-potential end and connected together at their high-potential ends through a second coupling reactance of the same character as the first to provide a circuit of constant selectivity and amplification over a given frequency range. In the intervalve coupling shown, two tuned circuits comprising inductances L and simultaneously variable condensers C have a common condenser Cm, at their earthed end and a condenser C<1>m connecting their high-potential ends. The condenser Cm is shunted by a resistance R1 to enable grid-biasing potential to reach the grid of valve T<1>. The circuit is coupled to a coil L1 in the plate circuit of the preceding valve T, or in a modification, for use as an aerial tuner, is connected to the aerial through a condenser. The coupling is preferably below the critical value necessary for the arrangement to become a band-pass filter and curves are shown demonstrating the effect on constant amplification of different values of C<1>m, Cm and the aerial condenser, and also the selectivity at different frequencies of a fixed circuit.

Title: Improvements in or relating to screens for use in electron discharge tubes and methods of forming such screens
IPC: H01J29/28
Filed: 1946-08-08
Abstract: 618,469. Coating glass surfaces. CINEMATELEVISION, Ltd., and LANCE, T. M. C. Aug. 8, 1946, No. 23572. Addition to 606,819. [Class 56] [Also in Group XL (a)] Method of manufacturing a luminescent screen comprises binding particles responsive to cathode-rays or X-rays to a supporting surface by applying finely-divided glass and the particles in a dry state to the supporting surface, heating the glass until it melts and thereafter depositing on the surface of the layer so produced a thin coating of a conducting substance. As in the parent Specification, the finely divided glass may be mixed with the luminescent particles prior to their deposition on the supporting surface or may be applied separately to the supporting surface prior to the application of the luminescent particles. The glass may be one of the low melting point varieties and may be subjected to a controlled rate of heating during formation of the screen so that a high glaze is produced on the surface thereof on which the thin coating of conducting substance is to be deposited. The thin coating of conducting substance may be a thin metal (for example aluminium) film approximately six microns thick formed by evaporating metal on to the glazed surface of the screen. The luminescent screen may be formed with conducting surfaces on both faces by depositing the luminescent particles on a metallic layer which is not necessarily transparent if the front surface of the screen is used and which is self-supporting or supported by a framework and by depositing a transparent conducting film on the exposed surface of the luminescent material after it has been bound by the glass binding material. In a modification the screen after its formation is coated prior to the deposition of a metal film with a layer of glass having a lower melting point and/or surface tension than the glass used as binder.

Abstract: 460,534. Controlling reversing gearing. BENDIX, Ltd., CLARK, H., and WYNNE, C. H. L. Aug. 26, 1935, No. 23801. [Class 80 (ii)] [Also in Group XXXIII] In a marine engine plant wherein a forward and reverse gear is used a control mechanism is provided for a fluid-pressure servo-motor which adjusts the gear and simultaneously for controlling the engine throttle, the controlled mechanism incorporating cam motions. A control pulley 15 is movable by means of cable and has upon it a disc 16 in which are cam slots 26, 27, one of which takes the end 22 of the pivoted lever 20 which controls the engine throttles of carburetters 3 and the other takes the free end 25 of a pivoted lever 23 which is coupled by a rod 10 with the valve 8 of a servo-motor which adjusts the forward and reverse gear 4 through levers 5, 6. The middle portion A of the throttle lever slot 26 is approximately circular and has a greater radius than the minimum distance from the axis of spindle 14. The end portions B and C are straight and tangential to the middle portion so that as the disc 16 is rotated from its neutral position in either direction the roller 22 moves along the circular part A which diverges slightly from the pivot and the lever is first rocked to open the throttle sufficient to prevent the engine stopping when the gear is engaged, and on further movement of the cam, the roller enters one of the straight parts and the throttle is opened wider. The other slot 27 is shaped so that as the cam disc is moved from the neutral position D into the forward speed position G, the roller 25 moves away from the axis and the lever rocks to engage forward gear. On further movement the roller enters a portion of the slot H concentric with the spindle. Similarly on rotation in the opposite direction, the roller 25 moves inward towards the axis in the part E and the lever is rocked to engage the reverse and on further movement the roller moves in the concentric portion F and the lever is relatively stationary. The casing 13 is supported on brackets 12 and has a cover 19. The mechanism may control simultaneously two or more engines and their transmissions. Specification 408,357 is referred to.
