Title: Preparation of a soluble form of riboflavin
IPC: A61K31/525
Filed: 1947-02-20
Abstract: A soluble form of riboflavin is produced by heating it with urea, urethane, acetamide or nicotinamide until fused, an acidic salt being optionally added before or after heating; the proportions are preferably equimolecular, and the product may or may not be a definite chemical compound.  In the examples: (1) riboflavin is fused with urea, and monosodium phosphate, cooled and dissolved in water; (2) riboflavin is fused with nicotinamide, cooled and dissolved in water containing thiamine hydrochloride and pyridoxine hydrochloride; (3) riboflavin is fused with acetamide; (4) riboflavin is fused with urethane.  According to the Specification as open under Sect. 91, riboflavin and other isoalloxyazines, or derivatives thereof, may be fused with any amide.  This subject-matter does not appear in the Specification as accepted.ALSO:A soluble form of riboflavin is obtained by heating it (preferably in equimolecular proportions) with urea, urethane, acetamide or nicotinamide, an acidic salt being optionally added before or after the heating.  In an example, riboflavine is heated with nicotinamide until fused, cooled and powdered.  The product is dissolved in water containing thiamine hydrochloride and pyridoxine hydrochloride to give a solution of pH 4.9.  The compositions are stated to be useful for the administration of vitamins orally or by injection.

Patent GB-608193-A (GB)
Title: Improvements in or relating to photo-telegraphy systems
IPC: H04N1/036
Filed: 1946-02-18
Abstract: 608,193. Copying-telegraphy. KEMSLEY NEWSPAPERS, Ltd., and SPENCER, J. W. Feb. 18, 1946, No. 5026. [Class 40 (iii)] Photo-telegraphy apparatus having at the receiver a constant intensity light beam shining through an aperture in a screen is characterised in that relative displacements of the lightbeam and aperture for all grey tones deeper than a predetermined hue produce the same result as a " black " signal and all other displacements produce the same result as a " white " signal. The subject, e.g. a half-tone picture, is mounted on a drum which is rotated and moved axially in front of a photo-electric cell and light source to produce picture signals in a known manner. These signals are transmitted to a mirror-oscillograph receiver where they deflect the light beam with respect to an aperture, and hence determine the amount of light falling on a sensitized surface. The light-beam 4<1> (Fig. 7) at the receiver is the same width as the scanning spot 9 (Fig. 6) at the transmitter and four times the width of the receiver aperture 5<1> (Fig. 7). Thus, when the scanning spot 9 is crossing a black line 8, of width equal to the spot 9, the phases A<1> ... C<1>, which give rise to signals equivalent to grey tones, all cause the receiver beam 4<1> to completely illuminate the aperture 5<1>. Similarly, the four phases represented by C<2> ... D<1> all cause the receiver beam 4<1> to be deflected clear of the aperture 5<1>. A similar action of the receiver light-beam 4<1> results from the passage of the scanning spot 9 from the phase D<1> until it is clear of the line 8. Thus, substantially no grey tones are produced at the receiver and the line 8, while it may be twice its correct width, is clearly defined in black and white. A small grey tone may be produced by the receiver beam 4<1> between phases C<1> and C<2>, but this risk can be minimized by reducing the width of the aperture 5<1> so long as it still permits sufficient light to reach the sensitized surface. The position of the aperture 5<1> may be varied with respect to the swing of the receiver beam 4<1> to vary the point in the grey range at which the change from black to white reproduction occurs, and hence make the reproduction of the line 8 wider or narrower as desired. A suitable construction of a mask with an aperture adjustably controlled by a rack and pinion is described (Figs. 8... 10, not shown). The receiver may be distant or near and the Provisional Specification states that the electrical impulses produced at the transmitter may be suitably limited at the transmitter or the receiver so that only impulses above, or below, a critical value are allowed to influence the oscillograph mirror, cathode-ray tube or other light-varying device.

Title: Improvements in or relating to apparatus for colour photography
IPC: G02B27/14
Filed: 1939-02-16
Abstract: 529,707. Colour photography. HARRISON, W. H., and HARRISON, D. V. Feb. 16, 1939, No. 5197. [Class 98 (ii)] Apparatus wherein colour component images are obtained by means of an optical dividing system includes provision for view-finding comprising in succession a diffusing screen in each of the two paths of the divided beam, a fixed focus lens in each path, a semi-transparent surface in the path of one beam, a co-operating reflector in the path of the other beam whereby said beams are re-combined for inspection on the semi-transparent surface, and means for compensating for the difference in the lengths of the paths followed by the component beams. Means may also be provided to permit adjustment of the colour balance in the component images. The system shown in Fig. 1 comprises plano-concave and plano-convex lenses 11, 12 relatively adjustable for focusing, an inclined semi-transparent mirror 13, a parallel total reflector 14, fixed objectives 16, 17 focused for infinity and receiving the divided beams a, b from 13, 14, a diffusing screen 18 bearing colour filters 21, 22 on which the objectives 16, 17 form side-by-side component images, field lenses 25, 26 in the paths of the beams from the screen 18, a semi-transparent mirror 27 receiving one beam, a total reflector 29 receiving the other beam after passage through a glass compensating block 28 and reflecting it to re-combine with the direct beam on the mirror 27, an objective 30 receiving the re-combined beams, and a viewing eyepiece 31. The diffusing plate 18 bears register marks x, y, xl, y<SP>1</SP>, Fig. 4, and the block is tiltable to bring the pairs x, x<SP>1</SP>, and y, y<SP>1</SP> into alignment in order to register the finder images. Between the beam splitter 13, 14 and the objectives 16, 17 means are provided for adjusting independently the intensities of the divided beams, the means in one form comprising adjustable stop mechanism (Fig. 2, not shown), and in another form a pair of displaceable colour wedges of the same colour as the filters 21, 22. By making this adjustment when the recombined images are being viewed through the eyepiece 31, the apparatus may be set for producing component images 19, 20 of equal density, on a light-sensitive film which may be moved into position to take the place of the diffusing screen 18. The beam-splitter 10 may, if desired, be used for both finding and making the exposure. A modified system is described, using only one fixed objective instead of the pair 16, 17, the mirrors 13, 14 and 27, 29 being in this case not parallel, and the two divided beams a, b crossing at the objective. The apparatus may be used in still photography or kinematography.
