Abstract: 1308189 Comparison Photometers AGFAGAVAERT A. G. 25 June 1970 [27 June 1969] 30862/70 Heading G1P [Also in Division G2] A comparison photometer for use in photographic cameras comprises filter means 11 for producing a first coloured light beam from incident light 13 and means 12 for producing a reference beam of a different colour, and combining means 10 for combining the beams of different colours whereby the colour of the combined beam 13a, 14a is an indication of the intensity of the unknown beam. A reference beam 14 passes through a red filter 12 and is reflected at a grating surface 10a of combining means in the form of a prism.10. The incident light beam 13 of unknown intensity passes through a green filter 11 and through the grating surface 10a to combine with the emergent reference beam. The prism 10 may be replaced by a grating disc (17), Fig. 2 (not shown) and the filters may be any complementary colours. In another embodiment Fig. 1 (not shown), there is provided a green filter on one side of which is formed with a mirror grating (2). A beam (3) of unknown intensity incident at 45 degrees on the other side of the filter is combined with a red reference beam (4) incident at 45 degrees on the mirror. The mirror may reflect only red light, in which case the incident beam is white. The colours combined may be any different colours, preferably complementary. In a modification the reference beam may pass through the filter, while the incident beam of unknown intensity is reflected by the mirror. The mirror may be deposited by evaporation or be a printed aluminium coated film.

Title: Improvements in or relating to the purification of pteroylglutamic acid and related compounds
IPC: C07D475/04
Filed: 1947-11-21
Abstract: A pteridine of the formula <FORM:0650318/IV (b)/1> wherein -NHR is an amino acid or a peptide thereof, is isolated in the form of a zinc salt from a crude reaction mixture containing the free pteridine, by adding a soluble zinc salt to an aqueous solution of said crude reaction mixture and adjusting the hydrogen ion concentration thereof to within the range pH 10.5 to 11.2, and separating the solution of the resulting soluble zinc salt of the required pteridine.  The pH of the solution thus obtained may be adjusted to within the range 6.5 to 7 to precipitate said zinc salt and the solution may be heated to within the range 50 DEG  to 95 DEG  C. prior to adjusting the pH, e.g. the pH may be adjusted with acid or an acidic salt such as zinc chloride.  The zinc salt may be dissolved in an aqueous solution of alkali at a pH above 11.5 and precipitated again in accordance with the above process, and this procedure may be repeated a number of times.  The aqueous solution of the crude reaction mixture may first be treated with an alkaline earth metal hydroxide and the insoluble matter separated therefrom before adding the soluble zinc salt.  The process may be used for the purification of pteroylglutamic acid, pteroylglutamylglutamic acid, pteroyldiglutamylglutamic acid and other amino acid amides of pteroic acid.  The samples furnished under Sect. 2 (v) comprise pteroyl-alpha-glutamyl-glutamic acid (prepared from the zinc salt) and the magnesium salt of pteroyl-gamma-glutamyl-gamma-glutamylglutamic acid (prepared from the corresponding zinc salt).

[Also in Group XX] A clip (Fig. 13) for hanging film strips during processing, comprises a one-piece U-shaped metal strip, the limbs 1, 2, of which, terminate respectively in a tongue part 12 and a recessed part 6, the parts 12, 6, being diverted from their respective limbs in crossing relation, with the part 12 guided in the recess of the part 6, and the parts 12, 6, having mating teeth formed on jaws 7, 13, extending perpendicularly to the respective parts. The hanger is made from a flat stamped-out blank (Fig. 2, not shown), and flanges are turned up at right-angles to form the jaws 7, 13 (Fig. 3, not shown). The parts 12, 6, are then bent in the same direction, to an angle of 45 degrees to the plane of the blank (Fig. 4). The latter is then bent into U-shaped form, the tongue 12 being sprung between the sides of the recessed part 6. The clip shown in Fig. 13 has a lead weight 81 held by two tongues 78, 79 struck up from the blank. The tongues engage a recess 80 in the weight 81, and the latter may act to limit or offer resistance to deflection of the limbs 1, 2. Holes 76, 77, left by the tongues 78, 79, serve for the insertion of a hanger rod, although separate holes 28 (Fig. 4) may be provided for this purpose. There may be a plurality of tongues 12 and associated recesses 6 formed on the same clip (Figs. 10-12, not shown). In operation, the film is held between the teeth on the jaws 7, 13, which are urged into engagement by spring pressure from the limbs 1, 2. The axis of intersection between the parts 12, 6, serves to limit the degree of penetration of the film between the jaws.
