Title: Improvements in or relating to a process and apparatus for measuring the elevation and contour of a surface
IPC: G01N23/203
Filed: 1960-08-26
Abstract: 909,797. Radio-active following of surface contours. KOPPERS CO. Inc. Aug. 26, 1960 [Dec. 21, 1959], No. 29572/60. Class 40 (3). The elevation and contour of a surface are determined by irradiating a strip on the surface, causing a receiver to follow the line of maximum scattered radiation, and computing the profile of the strip from the angular positions of the detector. Radiation from a cobalt 60 source emerges from a slot in surrounding steel blocks to irradiate a strip 36, Fig. 10, on the surface 23 of the charge in a blast furnace 11. A timer motor 155, Fig. 8, periodically closes contacts to cause a receiver 35, to scan along the strip 36. The receiver comprises a cylinder containing collimating cavities 44, 43, Fig. 5, and detectors 39, 40 and is scanned along the strip by a motor 143. The receiver assembly is protected from heat by insulation 285 and by circulating cold air inside the housing 85. The outputs from the detectors 39, 40 are fed through amplifiers 217, 218 to energize motor 200 so that the receiver is rotated by a bead chin 195 about the axis 95 until both detectors are equally energized. Motor 143 is coupled to tangent and secant potentiometers 225, 245 respectively and motor 200 to a tangent potentiometer 255. The output of potentiometer 225 indicates the position of the point viewed by the receiver and the output of potentiometers 245 and 255 in series gives the elevation at that point. These outputs are fed to a recorder 53 which traces the profile of strip 36 1 . A signal from a difference detector 265 is also fed to recorder 53 to compensate for time lag in the follow system. In a manual embodiment, motor 143 is energized to rotate a desired position and the receiver has a single detector which is adjusted until its output is a maximum. Motors 143 and 200 are connected by flexible couplings to meters indicating their position. In further embodiments a second source 29 may irradiate a second strip 36 11 , or the source may be above the centre of the strip. The receiver may be fixed and the source rotatable or both may be rotatable.

Title: Combined polychromatic and monochromatic television system
IPC: H04N11/12
Filed: 1947-11-07
Abstract: 666,482. Television. RADIO CORPORATION OF AMERICA. Nov. 7, 1947 [Dec. 5, 1946], No. 29718/47. Class 40 (iii). In a combined monochromatic and polychromatic television system at least one of a plurality of simultaneously developed discrete sets of signals each representative of a different one of a like plurality of component colours of the image being televised are combined with at least of the remaining sets of signals, the combined signals alone being reproducible as monochromatic pictures by a conventional black-white television receiving systems and all of the sets of signals as polychromatic pictures by a polychromatic receiver. In the arrangement described which employs a threecolour simultaneous system three separate television cameras are used to generate the colour component image signals two of the cameras 15, 20 (Fig. 1), being provided with red and blue colour filters 14 and 21 respectively and the third camera 30, with a colour filter 31 which transmits green light together with a predetermined amount of both red and blue light. The signals developed by the cameras are then individually modulated on to separate carriers which, after side-band suppression, are fed to the transmitting equipment. For colour reproduction at a receiving station the red and blue component signals which are fed to red and blue image reproducing devices are also employed, by combining in opposition and in suitable amplitude with the composite green and red-blue signals, to separate out the green component signals which are then fed to a green image reproducing device, a coloured reproduction being obtained by the (optical) addition of the three component colour images. For monochromatic reproduction a conventional black-white receiver is tuned to the carrier frequency of the composite green, redblue signals from which a monochromatic (black-white)image is produced. Specification 666,480 is referred to.
