Title: Colour television camera system
IPC: H04N9/09
Filed: 1962-06-07
Abstract: 974,140. Colour television. RADIO CORPORATION OF AMERICA. June 7, 1962 [June 27, 1961], No. 22119/62. Heading H4F. In an N.T.S.C. colour television camera system, the luminance signal Y 2  representative of the sum of the luminances of all the component colours present in the scene to be reproduced is derived from a high resolution picture pick-up tube such as the image orthicon 14 whilst the colour signals R, G, B, are derived from separate low resolution tubes such as the vidicons 11, 12, 13. The scene to be transmitted is imaged on the tubes by lens 16, 16<SP>1</SP>, 1611, half-silvered mirror 17 and dichroic mirrors 18, 19, 21. The light to the image orthicon 14 may additionally be passed through filter 22, which, together with the image orthicon 14 has a spectral response comparable to that of the human eye. Gamma correction circuits 23, 24, 26, 27 may be provided, although sufficient gamma correction may be obtained from the pick-up tube characteristics. The luminance signal Y 2  may be added to a 3.58 mc./s. colour sub-carrier (modulated by I and Q colour difference signals derived from colour signals R, G, B) and transmitted in conventional manner (Fig. 1, not shown). However the Specification shows that the required peak to peak amplitude A 2  of the colour ub-carrier differs from the actual value A 1  by a factor Y 2 /Y 1  where Y 2  is the gamma corrected luminance signal derived from the image orthicon 14, i.e. Y 2  = (0.3OR + 0.59G + 0.11B)<SP>1</SP>/γ, and Y 1  is the " colour ideal " luminance signal, i.e. Y 1  0.3OR<SP>1</SP>/ #  + 0.59G<SP>1</SP>/ #  + 0.11B<SP>1</SP>/ # . The circuitry 37 being provided to correct for this error. To obtain the sub-carrier A 2  the luminance signal Y 1  derived in known manner from the colour signals R, G, B is D.C. restored and applied to circuit 37 together the luminance signal Y 2  (also D.C. restored) and the colour sub-carrier A 1 . The circuit 37 derives the function A 1 Y 2 /Y 1    by means of logarithmic circuit elements, e.g. A 2  = antilog (log A 1 +log Y 2 -log Y 1 ). This corrected colour sub-carrier is added to the luminance signal Y 2  for transmission to the receiver. Since the luminance signal Y 2  is not derived from the three colour signals R, G, B it may be transmitted separately for reproduction on a conventional black and white receiver.

Title: A new or improved process for the softening of water
IPC: C02F5/02
Filed: 1920-07-24
Abstract: 173,255. Hepburn, G. G. July 24, 1920. Liquids, purifying.-Water is softened by filtering it through a mass consisting of or containing insoluble or difficultly-soluble salts of alkali metals with humic or ulmic acids, so that similar insoluble salts of the alkaline-earths are formed, and remain in the filter, in which they can be regenerated into the salts of the alkali metals for further use. For example, a hard water is treated with raw peat or peat which has been treated with a solution of alkali salt, such as sodium chloride; alternatively, humic or ulmic acid substances are used in combination with quartz, sawdust, or other inert diluents. The peat may be enriched with these substances. Used peat is regenerated by treatment with a solution of an alkali salt, such as sodium or potassium chloride, the anion of which can form an easilv-soluble salt with the metal to which the hardness of the water is due. When humic or other peaty acid is used it is preferable to convert it into an alkali salt by means of caustic or other alkali such as caustic soda or sodium carbonate. According to the Provisional Specification. the peat may be treated with magnesium or aluminium salts to prevent it from discolouring the water, or with calcium hypochlorite, chlorine, or other bleaching-agent.
