Abstract: 1,217,984. Colour television camera. SONY CORP. 14 Feb., 1969 [14 Feb., 1968], No. 8221/69. Heading H4F. Image light is projected via a striped colour filter 6, Fig. 3, comprising a repeating sequence of red, green, blue and opaque index filter strips, Fig. 4 (not shown), on to a pick-up tube 3 e.g. a vidicon tube, and the resulting output signal is gated 17, 18 using pulses derived from the index strips to produce red, green and blue primary narrow-band colour signals R s , G s  and B s  which are fed to a compensating circuit 21. Signals R s , G s  and B s  are also added in circuit 20 to produce a composite signal M s  which is fed together with the output of a low-pass filter 22 which comprises M o  = R o  + Go + B o  to a compensating circuit 21 in which the signals B s , G s  and B s  are respectively multiplied by the ratio M o /M s  to derive wide-band colour video signals R, G and B. In a further embodiment, Fig. 1, the image light is projected via dichroic mirror 10 which passes red and blue light and a striped colour filter 6 comprising a repeating sequence of red, blue and opaque index filter strips on to a first pick-up tube 3, and via the dichroic mirror which reflects only green light on to a second pick-up tube 14. From the output signal of tube 3 red and blue primary colour signals R s  and B s , a composite signal M s  = R s  + B s  and a low-frequency component signal Mo = R 0  + B o  are derived as in Fig. 3 and fed to a compensating circuit 21 in which the signals R s  and B s  are multiplied by the ratio Mo/Ms to form wide band colour signals R and B. The output of tube 14 is used for generating a luminance signal, and is applied to a low-pass filter 24 and a high-pass filter 25. The output Go of filter 24 is added to M o  in circuit 26 to produce signal Y o  which is fed to matrix 27, to form colour difference signals R-Y o  and B-Y o , and to an adder 28 wherein it is added to the output of filter 25 to form the luminance signal Y. The primary colour signals R s , G s  and B s  may be derived by synchronous detection, the frequency of the respective colour carriers being the same or different, Figs. 5 and 6 (not shown). A lens screen comprising a plurality of cylindrical lenses may be disposed adjacent the pick-up tube, an image of the striped colour filter being formed on the photo-conductive layer of the tube by each cylindrical lens, Fig. 8 (not shown).

Title: Improvements in or relating to the manufacture of aldols
IPC: C07C45/72
Filed: 1945-04-06
Abstract: Aldols are prepared from unsubstituted acetaldehyde and its homologues by effecting aldolisation with an alkaline catalyst using as a diluent an amount of substantially anhydrous alcohol which is at least 20 per cent by weight of the initial alcohol-aldehyde mixture, adding to the reaction mixture an acid in a quantity at least sufficient to neutralize the catalyst and separating the aldol formed.  Preferably, the alcohol forms with the neutralized reaction mixture, a mixture boiling at a temperature below that at which the aldol is dehydrated, whereby removal of unreacted aldehyde by distillation at the end of the reaction is facilitated; desirably, the mixture is acidified to a pH value of 4 to 5 thereby reducing dehydration of the aldol.  A carboxylic aliphatic acid having from one to five carbon atoms is preferably used in acidifying the reaction mixtures; sulphuric acid is also mentioned.  The aldolization may be carried out as a continuous process or not and at ordinary or super- or subatmospheric pressure; it is applicable to the method described in Specification 634,562.  An example illustrates the preparation of acitaldol using ethyl alcohol as diluent; methanol and iso-propanol are also specified.  Butyraldol may be prepared in like manner.  The alcoholic solution of acetaldol obtained after distilling off unchanged aldehyde may be catalytically hydrogenated to butane-diol.  A table is given comparing the p yields of acetaldol and undesirable higher polymers obtained at different temperatures from solutions of acetaldehyde in water and absolute alcohol respectively.  The Specification as open to inspection under Sect. 91 includes the aldolization of any aliphatic aldehyde and is not limited as regards the amount of alcohol to be present.  This subject-matter does not appear in the Specification as accepted.
Patent GB-738199-A (GB)
Title: Epoxy aliphatic amino acids and salts
Inventor: BERSWORTH FREDERICK CHARLES
Filed: 1953-03-30
Abstract: The invention comprises epoxide compounds of the general formula <FORM:0738199/IV (b)/1> in which R is an aliphatic hydrocarbon group to two adjacent carbon atoms of which there is attached an oxygen atom and wherein at least one of the amino hydrogen atoms is deplaced by an acetate group, -CH2COOM, in which M is hydrogen, alkali metal, ammonium or substituted ammonium.  They may be produced by carboxymethylating a di-hydroxy aliphatic mono-amine, having at least one displaceable amino hydrogen and in which the two hydroxyl groups are attached to two adjacent carbon atoms, by condensing formaldehyde with an alkali metal cyanide in a hot alkaline solution in the presence of the amine; the alkali metal salt of the hydroxy-aliphatic amino acid so obtained is suspended in xylene or toluene and heated to convert the hydroxy groups into an epoxy group.  In the examples: (a) 2,3-dihydroxy propylamine is treated with sodium cyanide and formaldehyde in the presence of caustic soda; the anhydrous product is suspended in xylene and heated to give 2,3-epoxy-diacetic amino acid disodium salt of formula <FORM:0738199/IV (b)/2> (b) 3,4-dihydroxy butylamine is carboxymethylated by the process of (a) and the product is then suspended in xylene and heated to give <FORM:0738199/IV (b)/3> (c) 1-chloro-2-butene is heated with the disodium salt of imino diacetic acid in aqueous ethanol to give 1-amino-2-butene-N,N1-diacetic acid which is suspended in dioxane and treated with benzoyl peroxide to give <FORM:0738199/IV (b)/4>

Title: A process of and means for agitating and weighing milk and cream
IPC: A01J11/00
Filed: 1948-03-25
Abstract: 663,739. Sampling; weighing apparatus. KOTS, H. E., and KOTS, W. F. March 25, 1948. No. 8830/48. Classes 106 (v) and 143. [Also in Group II]. A process for agitating and weighing milk and cream with weighing devices having one or more weighing containers is characterised in that during or after the pouring of the milk into a weighing container the milk is stirred by means of a stirring device, after which stirring is terminated by stopping the stirring device or removing it from the container, and at the same time either a weight indicator which was previously locked is released, or a screen which previously obscured a weight indicator is removed, to enable the weight of the milk to be ascertained, the weight indicator being again locked, or obscured by the screen, when the stirring device is started again. Milk is poured into a weighing container 1, Fig. 2, where it is agitated by a stirrer 3 driven through a coupling 4, by a motor 5, and a sample is taken, through a pressure line 15, by sampling apparatus 14. A lever system 6, 7 is then operated by movement of a handle 11, firstly to lift the motor 5 and disengage the coupling 4, to disconnect the sampling apparatus, and to free an indicating device 2 of the weighing mechanism, then, on further movement of the handle 11 to open a discharge valve 9. Instead of disengaging the coupling 4 operation of the lever system may open the motor circuit. The stirrer may be driven through a disengage- :able V-belt drive. In a further embodiment, Fig. 5, the motor and stirrer are  lifted by hydraulic or pneumatic piston means 37, 39, which also operate a lever system 44 to displace cover plates 45 of a weighing scale 34 so that the exact weight may readily be read. The stirrer may be lifted by mechanical means. One stirrer may be lifted by mechanical means. One stirrer may be used to stir successively the contents of two containers. Stirrers may be carried at opposite ends of a pivoted lever and moved so that only one container is stirred at a time.
