Title: Improvements in control systems
IPC: F22B35/10
Filed: 1936-11-27
Abstract: 481,921. Electric control systems. BAILEY METER CO. Nov. 27, 1936, No. 32512. Convention date, Dec. 18, 1935. [Class 40 (i)] [Also in Groups XXIX and XXXV] In a control system for a vapour generator of the drumless forced-flow type the loading adjustment on the speed governor of the auxiliary turbine driving the pumps supplying liquid and the elements of combustion is actuated by an oil servomotor controlled by vapour outflow and vapour outflow pressure acting through an electric circuit including electron-discharge devices having variable area electrodes. A damper in the air supply conduit and a discharge valve on a separator are actuated by similar servomotors and control circuit, controlled by the level in the separator. The servomotors comprise spring- loaded pistons 92 housing pumps 91 adapted to be rotated at various speeds by electric motors 90 to pump oil from the space above the piston to the space below and so raise the piston against the action of a loading spring. The speeds of the motors are regulated by relay panels 72, 75 controlled by electron-discharge devices 69, 70, 74 having variable area electrodes. The movable electrodes of the devices 69, 70 are mechanically actuated by Bowden tubes subject respectively to vapour outflow pressure and to first stage turbine pressure which pressure has a straight line relationship with vapour flow. The movable electrode of the device 74 is actuated by a bellows subject to the hydrostatic head in the separator. The relay panels comprise electron-discharge devices associated with phase changing bridges adapted to control a pulsating direct current by impressing on the grid the sum of an A.C. and D.C. voltage. By varying the D.C. voltage, through the agency of the mechanically operated electrondischarge device, the point in the cycle at which the grid voltage reaches the threshold value and allows the device to conduct is varied. This varies the percentage of time during which the device conducts and hence the speed of the motor. Specification 475,561 is referred to.

Patent GB-435418-A (GB)
Title: Improvements in change-over mechanism for cinematograph apparatus
Filed: 1933-12-23
Abstract: 435,418. Kinematograph projectors. BOUCHER, F. M., 3, Dinsdale Gardens, New Barnet, Hertfordshire. Dec. 23, 1933, No. 32741. [Class 97 (i)] Change-over is effected by means of a light ray from an exciter lamp which is automatically put in action at a predetermined moment during the operation of the primary projector, and is instrumental, at the appropriate moment, and with the agency of a photo-electric cell or the equivalent, in causing the starting of the motor of the next projector to be used; the ray may be controlled by the passage of a junction between opaque and transparent parts of the film edge to effect the starting of the motor. As shown, pivoted arms 31 engage the film 13 coiled on the pay-out spools of each of two projectors, and carry mercury switches 35 which, when the film is nearly running out, complete the circuits of lamps 23. Each film 16 is provided with an opaque strip 15 on to which a ray from one of the lamps is then directed by a lens 17 ; the opaque strip terminates at about fifteen feet from the film end, and, when it has passed the ray, permits the ray to fall on a photo-electric cell 21 and operate through an amplifier 24 and relay 25 to tilt a mercury switch 29 and complete the circuit of the motor driving the other projector. A second mercury switch 37 on the arm 31 may operate a signal warning the operator to strike the arc of the other projector or may operate an automatically - fed arc. Means for automatically operating sliding cut-off shutters on the projectors when the motor has attained normal speed may be provided, and may comprise a disc 53, Fig. 5, on each projector driven through a clutch by a worm and wormwheel from the projector motor. The disc 53 carries an adjustable arm 91 against which the end of a lever 77 initially abuts, the arm being set by hand at such a point that the motor has attained full speed before a step 73 in the disc driven by the motor permits the lever 77 to fall. The lever, in falling, slides cut-off shutters 39, 41, to change the projection beam, either by means of a cord 83 or by electrical connections, and may also operate a sound fader 43 through a cord 89. Continued rotation of the disc causes the lever 77 to ride up the surface 71 to its original position, and brings a cam into position to engage a roller and break the clutch connection, thus terminating the rotation. A mercury switch may be tilted, when the rotation ceases, to operate an audible or visual signal warning the operator to prepare the projector for its next use and to adjust the disc to its initial position. Specification 381,171 is referred to.
