Title: Process for controlling the exit temperature of vapour flowing through a convection heating surface of a vapour generator
IPC: F22B35/00
Filed: 1975-09-17
Abstract: 1521126 Vapour temperature control process SULZER BROS Ltd 17 Sept 1975 [17 Sept 1974] 38236/75 Heading F4A A process for controlling the exit temperature of vapour flowing through a convection heating surface in a vapour generator comprises employing a control element to adjust the exit temperature and actuating the element by means of a comparison signal derived from the subtraction or division of two measured value signals: the first of which represents the rate of heat supply to the generator and the second of which represents the rate of flow of vapour through said surface. In the embodiment shown a forced flow steam generator 6 provided with superheater 7 and reheater sections 15, 17 feeds steam to high and low pressure turbines 11, 12. Fuel pump 41 and air blower 51 feed the burner and a measuring element 45 sends a signal representative of the rate of fuel supplied to a comparison point 81 where a signal from a flow measuring element 82 is subtracted. The resultant signal acts on an injection valve 31 which feeds attemperating water to a point 16 between the reheat sections to control the temperature of the reheated steam. The injection valve, in the absence of a signal from point 81, is controlled by a device 7 which receives a set value of 72 and signals from temperature sensors 71, 75, 76, 77. A power controller 63 acts, in response to a set-value delivered at 66 and to a signal from generator 65 driven by the turbines, to operate a load controller 60 which also receives the output of a steam pressure measuring device 62. The controller 60 acts on fuel and air supply controllers 46, 56 which also receive flow measurement signals from the element 45 and an element 55. In addition a signal on line 92 from the controller 60 acts on a function generator 91 which operates a multiplication element 90 at the output of the comparison point 81. This ensures that a greater signal is applied to valve 31 in those load ranges in which a relatively large proportion of the heat evolved by the fuel is given up to the reheated sections. Element 90 can alternatively be disposed in line 80 and line 80 can be fed from element 55. The comparison signal can act alternatively on the blower 51 on a burner tilt control or on flue gas recirculation means to control steam temperature. Steam from turbine is condensed at 22 fed by pump 24 to steam-heated pre-heaters 25 and feedwater tank 1. Pump 2 delivers water via valve 4 and steam-heated pre-heaters 5 to the generator. A tachometer 68 on turbine 11 controls an inlet valve 10.

Title: Travelling wave oscillation generator
IPC: H01J25/40
Filed: 1956-12-14
Abstract: 832,531. Backward-wave tubes. STANDARD TELEPHONES & CABLES Ltd. Dec. 14, 1956 [Dec. 20, 1955], No. 38286/56. Class 39(1). In a travelling wave tube the beam passes through a first delay line section 15, Fig. 4, terminated non-reflectively at both ends to generate backward wave oscillations therein, the backward wave oscillations velocity modulating and bunching the beam and the bunched beam giving up energy to a second separate delay line section 17 supporting a forward wave from the far end of which the output is taken, the forward-wave section being arranged to have a falling output power/frequency characteristic compensating for the rising characteristic of the backward wave section, so that an overall flat response is obtained. Due to the absence of an output circuit the characteristic of the backward wave section is smooth. The delay lines are preferably both helices, as shown, but may be replaced by other delay structures such as interdigitated lines. The beam is preferably annular (generated by a ring cathode 11) and can pass outside both helices, Fig. 3 (not shown) or inside the first helix 15 but outside the second helix 17, as shown, to an annular collector 12, the beam being focused in the central portion of its travel by a solenoid 18. The cathode and beam need not be ring shaped ; e.g. the beam can be ribbon shaped or generally of hollow form. The reflectionless terminations 13, 14, 16 are graphite coatings on the helix support rods. The output helix is preferably given a non-circular, e.g. elliptical cross section so as to avoid cancellation of space harmonies varying angularly around the helices. The output is taken to a coaxial line by a tapered pitch and diameter helix section and a flared continuation of the outer conductor 19 of the coaxial line.

Title: Process and apparatus for the production of perforated foils or nets of thermoplastic material
IPC: B26F1/22
Filed: 1960-11-09
Abstract: 900,083. Making perforated plastic foil. ROSEDALE ASSOCIATED MANUFACTURERS Ltd. Nov. 9, 1960 [Nov. 27, 1959; July 18, 1960], No. 38512/60. Class 87(2). A plastic foil is provided with perforations such as holes or slits and the foil is then stretched in a hot condition and cooled whilst still subjected to the stretching force. A foil 1, Fig. 1, is passed between a cutting roller 2, with interchangeable cutters 3, and a pressure roller 4 with a flexible layer 5, so that the foil is perforated. The foil 1 may be heated by radiation as at 16 or the rollers 2, 4 may be electrically heated. Two rollers provided with cutters may be used. The heated foil is stretched in the direction 9 by a roll pair 11, 11 which runs at a higher (but variable) peripheral speed than the rollers 2, 4. The foil may be cooled in the stretched condition by an air blast as at 17 or the rollers 2, 4 may be water cooled in the case where heating is by radiation at 16. If the cutters produce slits in the foil, Fig. 4 (not shown) these will appear when stretched as the holes 13 in Fig. 5. On leaving the rollers 2, 4 the foil may be turned through 90 degrees in which case, on stretching, the edges 22 of the holes 13 will be displaced from the plane of the foil and this displacement will remain after cooling. The foil may also be stretched laterally, Fig. 12, where the foil 37 is engaged by roller pairs 38, 39 which have roughened surfaces or small hooks to grip the edges of the foil. In a typical process the foil after extrusion is passed through a perforating roll or rolls, which may be wetted with a liquid to prevent sticking of the foil and then to a lateral stretching device. The foil may then be passed, to a colouring bath and further to a longitudinal stretching device and an afterstretching device which may be arranged to stretch the foil to its condition of maximum strength. In modified arrangements the foil may be stretched partly before perforation or subjected to further stretching after cooling.
