Patent GB-1192031-A (GB)
Title: Colour Signal Generating Apparatus
IPC: H04N9/07
Filed: 1967-06-12
Abstract: 1,192,031. Colour television. SONY CORP. 12 June, 1967 [15 June, 1966], No. 27008/67. Heading H4F. [Also in Division G2] The invention relates to a colour television camera, Fig. 1, comprising a single pick-up tube 7 operated in conjunction with a three-part filter 8 and a cylindrical lens screen 9 whereby the image is broken up into a repeating sequence of red, green, blue bands which may be scanned with transverse lines to produce a dot-sequential type signal. In accordance with the invention, in one form, the filter 8, Fig. 7, is surrounded with an opaque member 14 whereby a shadow is produced between each group of three colour bands resulting in the production of a black level signal interval. Furthermore, a light source 17 (a row of lamps or an electroluminescent element) is disposed on the opaque member 14 parallel to the filter elements 8. The resulting signal, Fig. 5D, comprises a white level signal component 13M, located in the back level interval separating each cycle of colour signals 13R, 13G and 13B. Such a signal provides a positive indication of the start of a cycle even when the colour signals reduce to black level. The white signal may have such a width that it may be separated from the colour signals by a band-pass filter. A plurality of light sources may be used to provide a plurality of white signals. In another form of the invention, Fig. 10, a light source 17 is provided in a direction parallel to the filter elements 8B, 8G and 8R whilst a plurality of further light sources 18 are provided in a direction transverse the filter elements. The resulting signal appears as shown in Fig. 5F with white pulses 13M in the intervals between each colour cycle produced by source 17 and the colour signals all raised in level above the black level due to uniform illumination produced by sources 18. The shape given to the lower edge of source 17, the shape given to the upper and lower extremities of sources 18 and the zig-zag shape given to the edges of the filter elements 8B, 8G and 8R result in the signal transitions all being less steep than the rear edges of white pulses 13M. This factor in conjunction with the bias level imparted by sources 18 cause pulses 13M to be quite distinct and separable from the signal train by differentiation. A third form of the invention, Fig. 9 (not shown), uses only light sources 18 whereby the colour signals are raised above black level to provide distinguishable signals in the intervals between cycles. The cylindrical lens screen may be attached to the pick-up tube face plate or formed directly thereon. Alternatively, a lens or optical fibre system may be included in the light path between the screen and tube. Signals of high resolution may be obtained by operating the camera as described above in conjunction of luminance signal pick-up tube.

Abstract: 378,689. Liquid and gaseous fuel burners. MICHAEL, N. F., 91, Barlogan Avenue, Cardonald, and YOUNG, A. J., 130, Katherine Avenue, Linthouse, both in Glasgow. Oct. 5, 1931, No. 27579. [Class 75 (i).] In a steam generator in which the gas or liquid fuel supply to the burners is automatically cut off when the water in the steam generator falls below a predetermined level, hand controlled means are provided for causing the operation of the cut-off mechanism. In the apparatus shown the control valve 4 in the fuel pipe I leading to burners L is held open by a detent 7 which is normally maintained in engagement with the valve stem against the resistance of a spring 16 by the pressure of the feedwater on a stepped piston 8 in a cylinder 10 connected by a branch pipe 13 to a.pipe E leading from the feedwater pump G. A fall of the water lever in the steam drum A operates a float valve in a chamber D or the steam drum to allow the feed water or steam to pass to a cylinder 9 in which the larger end of the piston 8 slides. The piston is thereby operated to disengage the detent 7 and the valve 4 is closed by a spring 6. The piston 8 may also be operated to effect the closure of the valve 4 by opening by hand either a valve M admitting steam to the cylinder 9 or valves P, R relieving the feedwater pressure in the cylinder 10. The valve 4 may be replaced by means operated by the piston 8 for diverting the fuel supply to a return pipe leading to the suction side of the feed pump. A single hand-operated valve may be used to divert the feedwater pressure from the fuel control mechanism of the several fuel burners of a group of steam generators.
