Patent GB-635377-A (GB)
Abstract: 635,377. Rontgen-ray apparatus. METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. Aug. 28, 1947, Nos. 23860 and 23861. Convention dates, July 19, 1944. [Class 98 (i)] A series of separate radiographs of a body taken in the same effective direction are recorded on a single photographic plate or film by a method which consists in producing successive X-ray images corresponding to the radiographs on a fluorescent screen, optically projecting these images on to a photographic plate or film through a slit fixed in position with respect to the fluorescent screen, and through a lenticular 'screen formed with horizontal convex refracting elements parallel to the slit and to each other, whereby each image is projected on to the plate or film as a plurality of parallel, vertically separated strip images, and between the recording of successive images rotating the lenticular screen and the plate or film about an axis parallel to the refracting elements, whereby the strip images resulting from one image are interlaced on the plate or film with the strip images resulting from the other images in such a manner that when the developed plate or film is viewed through a similar lenticular screen, one of the images may be selected and observed. For recording a series of views showing different cross-sections of the body, the fluorescent screen (together with the optical system, lenticular screen, and photographic plate or film) and the X-ray source are movable relatively to each other and to an intermediate plane in known manner so that the images of points in the said plane, but no other plane, are stationary on the fluorescent screen. As shown, the apparatus includes a fluorescent screen 4, a projection lens 5 with a slit diaphragm 6, and a lenticular screen 7 backed by a photographic plate or film 8 rotatable together about a horizontal axis 9 parallel with the lenticulations 7a. An image is formed by an X-ray source 1 on the screen 4, both of which are movable in known manner to produce a stationary image of those parts only of a body 2 lying in a plane 31 thereof, parallel to the screen. The image on the screen 4 is recorded on the plate or film 8 as a series of strip images. The plate or film 8 and its screen 7 are rotated on the axis 9, so that when an image of another aspect of the body 2, e.g. a section on the plane 3<SP>11</SP>, is recorded the strip images lie between the strip images first recorded. Images corresponding to other aspects are similarly recorded to give an interlaced system of strip images. The developed plate or film is viewed through a lenticular screen similar to that used for recording, by which the strip images for any aspect are selected and reconstituted.
Patent GB-742346-A (GB)
Abstract: 742,346. Automatic control systems. SMOOT, C. H. Nov. 23, 1953 [June 3, 1953], No. 32408/53. Class 38 (4). [Also in Group XXIX] In a steam boiler, the fuel and air supplies to the combustion apparatus are controlled in accordance with steam flow, and the fuel supply is additionally, controlled in accordance with steam pressure, this latter control including an anticipatory or differential control. In an embodiment, the steam flow is measured by passing the steam through a restriction 19, Fig. 1, and applying the pressures on the two sides of the restriction to opposite sides of a diaphragm 20. The latter is connected to a pivoted baffle 22 co-operating with a nozzle 23 supplied wjth pressure fluid which has passed a restriction 24. The resultant pressure upstream of the nozzle is applied firstly to a diaphragm 25 connected to the baffle 22 to recentre the latter and, secondly, to a servo-piston 27 which positions the slider 29 of a potentiometer connected across an alternating supply 32. The voltage developed on the slider is applied across a resistance 49, Fig. 2, and a portion of that voltage is fed into an amplifier 52 to control a two-phase reversible motor 33 regulating the air supply 15 to the boiler combustion apparatus. A negative feed-back voltage is obtained by mechanically connecting the motor to the slider 53 of a potentiometer across the supply 32, this voltage being fed into the amplifier 52. The outlet steam pressure is measured by applying it to a diaphragm 36 which is connected to a pivoted baffle 37 controlling the escape of pressure fluid from a nozzle 38. The pressure fluid is applied to the nozzle past the smaller side of a differential piston 41 and a restriction 44, and the fluid pressure upstream of the nozzle is applied to the larger side of the piston. Piston 41 carries the cylinder of a dashpot 42, the piston 'of the dashpot being connected to the baffle 37 to recentre the latter, i.e. the overshoot of the response of piston 41 is corrected after a delay determined by the leakage past the piston of the dashpot. Piston 41 is connected to the slider 46 of a potentiometer 47 and the voltage developed on the slider is fed into an amplifier 62 to control' a motor 48 regulating the fuel supply 13 of the combustion apparatus of the boiler. A negative feed-back voltage is applied to amplifier 62 in the same manner as with motor 33. Potentiometer 47 is connected across the secondary of a transformer 58 of which the primary is fed from the slider of a potentiometer 61 connected across the supply 32. The voltage on slider 29 due to steam flow is added algebraically to that on slider 46 due to steam pressure by connecting slider 29 to the centre point of the secondary winding of transformer 58. In a system comprising two boilers feeding into a common output, the steam flow from each boiler is measured separately and controls its own air supply but the steam pressure is measured only in. the common output main.
