Filed: 1954-01-26
Abstract: 780,486. Rolling. BRITISH IRON & STEEL RESEARCH ASSOCIATION. Jan. 11, 1955 [Jan. 26, 1954], No. 2323/54. Class 83 (4). [Also in Groups XIX, XXXV and XXXVIII] In a multi-stage rolling mill for rolling wide steel or other strip, the thickness (h 2 ) of strip leaving the mill is measured, and indicated, by compounding signals representing the speed (v 1 ) and thickness (h 1 ) of the strip between two successive stages with a signal representing the speed (v 2 ) of strip leaving the mill, the product of speed and thickness being constant at all rolling stages. The derived signal representing (h 2 ) is compared with a reference value, and the resultant difference signal used for controlling the mill to maintain (h 2 ) at a desired value. The strip 15 passes between successive rollers 12a, 12b, 12c for intimate winding on a reel 20, driven by a motor 21, the rollers being driven by motors 22, and being adjustable by motors 23. A tachometer generator 19, associated with a speed sensing disc 18, has its output, representing the speed v 2 , applied to an arcuate potentiometer 25, a proportion of this output being tapped by a slider 26 for feeding to the input of a high-gain amplifier 27 in series opposition with the output of a second tachometer 17 representing the speed v 1 . The output of amplifier 27 energizes a motor 28 whose shaft carries slider 26, whereby the latter is adjusted to give zero input to the amplifier so that the proportion of the output of tachometer 19 which is tapped by the slider is in the ratio v 1 /v 2 . The output of a micrometer 13, representing the thickness h 1 , is applied to a second potentiometer 30 and a proportion, representing v 1 h 1 /v 2 , and thus h 2 , is tapped by a slider 29 adjustable by the motor-shaft in correspondence with slider 26. The output of slider 29, which operates an indicator 31 showing the value of h 2 , is compared with a reference value set on a potentiometer 33, the resulting error signal being applied to any of motors 21, 22, 23 to control the mill, thereby maintaining h 2  at a required value. In a modification, signals representing percentage deviations of v 1 h 1  and v 2  from set values are opposed to give a control signal representing the percentage deviation of h 2  from the required value.

Title: Control for jet engines utilizing variable area exhaust jet
IPC: F02K1/16
Filed: 1952-01-29
Abstract: 750,476. Jet propulsion plant. BENDIX AVIATION CORPORATION. Jan. 29, 1952 [Feb. 24, 1951], No. 2430/52. Class 110(3) [Also in Groups XXIX and XXXV] In a control system for a gas turbine engine having an exhaust jet of variable area, the jet area is reduced by a hydraulically actuated bullet valve as the fuel supply is increased by a speed governor in response to the pilot's control, provided that the engine speed is above a predetermined value, and, under these conditions. subject to an automatic electric override to prevent the tail pipe temperature from rising above a, predetermined upper limit. The pilot's control is assumed to vary the spring setting of a mechanical speed governor controlling the fuel supply by a hydraulic servomotor as in Specification 750,472. Simultaneously, it varies the setting of cam 52, Fig. 2 (via link 23 and gearing 57, 56, 55). which is so shaped that beyond the "idling" sector of the pilot's control it moves links 51, 48 to slide a cam 37 along a splined shaft 38 to move a pilot valve 31 controlling the hydraulic ram 25 actuating a bullet valve 16 controlling the jet area. Positional follow-up is provided by a rack and pinion 66, 67 controlling a cam 58 which re-adjusts the valve 31 in a similar manner. Whilst the engine speed is below a preset value, a centrifugal switch 86 is closed to energize an electric motor 39 to rotate the cam 37 to the full line position in which valve 31 is held in such a position that the jet area is maintained at its maximum regardless of the setting of cam 52. However, provided that the engine speed is above this value and the tail pipe temperature is below an upper limit, the cam 37 is rotated by a spring 41 to the dotted line position, and the jet area will decrease as the fuel supply is increased. Should the tail pipe temperature rise above the limit, the motor 39 is automatically energized (see Group XXXV) to move cam 37, back towards the full line position to reduce the temperature and to maintain it at its upper limit. Specification 626,045 also is referred to.
