Title: Vapor generator and method of operating the same
IPC: F22B35/08
Filed: 1965-06-02
Abstract: 1,079,164. Critical pressure boilers; regulating steam temperatures. COMBUSTION ENGINEERING Inc. June 2, 1965 [June 4, 1964], No. 23596/65. Heading F4A. The reheat steam outlet temperature of a supercritical forced flow steam generator operating with a limited recirculation, is controlled by varying the working medium return flow through valve 40 and conduit 42 from the furnace tube inlet to the inlet of economizer section 14, so as to reduce heat absorption from the combustion products in this section and increase the temperature of the products at the primary steam reheat section 30. Feedwater passes through economizer portions 12, 14 to mixing vessel 18 to mingle with the recirculated portion of the working medium. The flow then passes through recirculating pump 36 furnace tubes 20 and outlet pipe 22, whence part is recirculated to mixing vessel 18 through line 38 and the remainder passes through superheater 24 to a high-pressure turbine (not shown). Reheat steam returns through line 28 to steam reheat sections 30, 32. Controller 52 adjusted by reheat steam outlet temperature sensor 48 varies throttle valve 40 to maintain this temperature at a desired value. Gas recirculation may be used to maintain the primary superheated steam outlet temperature. In a modification (Fig. 2) the return flow to the economizer is drawn solely from the recirculated portion of the working medium.

Title: Improvements in apparatus for separating occluded gases for liquids
IPC: B01D19/00
Filed: 1957-07-26
Abstract: <PICT:0817925/III/1> To avoid overloading an air separator 9, aerated liquid is delivered through conduit 1 into an antechamber 2 communicating through chamber 3 with the valve chamber 4.  Part of the liquid from chamber 3 passes through an orifice 6 when the latter is not closed by the float member 5 and the liquid then flows up the riser tube 8 of the separator 9.  If the quantity of air which passes through the pump per unit of time exceeds that which the separator can liberate the float member 5 descends due to the increase of air in chamber 4, which can only escape through restricted orifice 4a; the flow through orifice 6 is obstructed; the pressure rises and the pump is able to deliver less and less liquid until the device can once more operate in the conditions favourable to the working of separator 9.

Title: Combined television and cinematographic equipment
IPC: G03B27/72
Filed: 1965-06-03
Abstract: 1,087,742. Television. COMPAGNIE GENERALE DE RADIOLOGIE. June 3, 1965 [June 3, 1964], No. 23801/65. Heading H4F. Combined radiological television and cinematographic equipment comprises means for automatically diminishing the target voltage of the television camera tube in proportion to an increase in the exposure rate of the cinematograph camera since the quantity of light received by the television camera tube increases when the exposure rate of the cinematograph camera is increased due to an increase in the amount of X-radiation from the X-ray tube. Decreasing the target voltage ensures that the beam current which is correct for a target voltage suitable at a low exposure rate, is sufficient to maintain constant the quality of the image supplied by the camera tube at a high exposure rate. As shown, the equipment comprises an X-ray tube 1, an object or person 2 to be X-rayed, an image intensifier 3, an optical system 4, a semi-reflecting mirror 5, a cinematograph camera 6, a camera tube 7 and a television receiver 8. To maintain constant the quality of the images supplied by the camera tube 7, which receives different quantities of light proportional to the X-radiation corresponding to the different exposure rates of cinematograph camera 6, a variable D.C. voltage is introduced in opposition to the voltage applied to the target of tube 7. This D.C. voltage may be obtained from a dynamotachometer or a generator intended for telemetering the exposure rate or for synchronizing the sound in the camera 6, and applied in opposition to the base of the D.C. generator supplying the target voltage. Alternatively, all or part of the supply voltage of the motor of the cinematograph camera may be used and part of this voltage may simultaneously be applied to the device fixing the black level of the television equipment, raising this level in proportion to the decrease in the target voltage of the camera tube.
