Filed: 1946-10-11
Abstract: 631,881. Electric coils. FAUDELL, C. L. Oct. 11, 1946, No. 30343. [Class 35] [Also in Group XL (a)] A magnetic lens for focusing the electron beam in a cathode-ray tube comprises a main coil 4 and an auxiliary coil 7, the coils 4, 7 producing unequal opposed fluxes and the arrangement being such that the resultant flux is substantially independent of temperature variations. This may be achieved by making the coils of wires of different gauges and/or materials of different specific resistances. The auxiliary coil 7 and a variable resistance 8 are connected in series with one another and in shunt with the main coil 4; alternatively, the resistance 8 is connected in shunt across the main coil 4 but is not connected in series with the auxiliary coil 7, or the resistance 8 is connected in series with the coil 4. The Provisional Specification states in addition that the resistance 8, which may be fixed or variable, may provide the desired temperature compensation. If the resistance 8 is fixed, an auxiliary variable resistance can be employed to ajust the beam focus. In this case the auxiliary resistance may be connected in series or in shunt with the coil 4. The auxiliary coil 7 is of ferromagnetic material such as fine iron wire and the main coil is of copper wire, so that the auxiliary coil 7 also acts as a shroud for the main coil 4.

In an arrangement for reproducing television pictures in which deformation produced in a control layer included in a Schlieronoptical system consequent upon scanning with a picture signal modulated cathode-ray beams are employed to modulate light from a local source, the control layer is carried by a concave mirror. In the apparatus shown in Fig. 2, rays from a light source 9 reflected by a mirror 14 illuminate a rectangular area of the control layer 15 which is carried on a concave mirror 17. The mirror 14 has alternate reflecting and transparent strips, Fig. 3, the reflecting strips 19 having black borders 20 and the whole acting as the equivalent of the system of bars and slits described in Specification 674,342, so that when the control layer is undeformed, light reflected back from the surface of the concave mirror is reflected again by mirror 14 back to the source. The illuminated area is scanned by a cathode-ray beam modulated at a high frequency by a high-frequency carrier wave modulated by the video signals and the deformations of the control layer surface caused by the scanning beam cause the reflected light beam to pass in corresponding amounts between the reflecting strips 19 of mirror 14 to produce an image on a screen 23. The concave mirror 17 is held by a spring 28 against rollers 27 and is slowly rotated about its central axis 32 by a motor 31, and a cooling system 33 is provided. The source of light 9 may be an arc lamp, two arc lamps used alternately or a series of mercury-vapour lamps. To avoid edge distortions, a stop 37 with a a rectangular opening having one rounded corner, Fig. 7 (not shown), is placed over the scanned area. A colour filter may be introduced into the plane 16 for colour reproduction. Specifications 543,485 and 548,643 also are referred to.

[Also in Group XIX] Apparatus for the optical examination of the form and dimensions of the surface profile of rod or tubing comprises a concave mirror to provide substantially a point focus for a beam of light incident on the mirror parallel to its optical axis, means for supporting at least part of the rod or tubing coaxially with the mirror and means for confining the illumination of the rod or tubing to a peripheral strip at the focus and an optical system comprising a lens and a screen on the opposite side of the mirror whereby light reflected from the strip and passing through an axial hole in the mirror is projected by the lens to form an image of the strip on the screen. Two concave parabolic mirrors 1, 2 with central circular holes 3, 5 are arranged coaxially with the filament of a 240 w. 26 v. lamp 4 centred on the focal point of the mirror 1 which reflects a parallel beam through a heat-absorbing glass sheet 14 on to the mirror 2 which then focuses reflected light on a strip of tubing supported symmetrically about the focal point by a guide tube 11 and frusto-conical portion 8 of a tubular member 6 fitted in the hole 5 of the mirror 2. A lens system 9 projects an image of the illuminated strip on to a screen for examination. The tubing enters the guide 11 by a cranked part 12 and leaves the tube 6 through a hole 10. A screen 13 prevents direct rays from the lamp 4 or mirror 1 from falling on the strip. A number of strips of heat-absorbing glass may replace the sheet 14. In another embodiment the axes of the mirrors are at right angles, light being directed from the first mirror to the second by means of a plane mirror inclined at 45 degrees to the intersecting axes, in this case the guide for the tube need not be cranked, a straight guide could pass through the plane mirror. A fan may be incorporated to draw cool air through the illuminated chamber. The parabolic mirrors may be replaced by simple concave spherical mirrors forming only small segments of a sphere, or by concave spherical mirrors fitted with convexoconcave lenses for producing a parallel beam or bringing a parallel beam to a focus. The lamp may be combined with any suitable lens system for producing a parallel beam.
