Title: Improvements in or relating to photographic cameras
IPC: G03B7/06
Filed: 1957-03-15
Abstract: 855,337. Photographic cameras. GAUTHIER G. m. b. H.,A. March 15, 1957 [March 15, 1956], No. 8652/57. Class 98(1) In a photographic camera having either the shutter speed setting member or the diaphragm setting member coupled with the follow-up member of an exposure meter, the diaphragm may be set for flash exposures in dependence on the distance of the subject and the power of the flash, for a given shutter speed, or vice versa, by means of a range scale and a flash power scale which are adjustable relatively to each other with one scale fixed and the other on the follow-up member, or with both scales on the follow-up member, the movable scale being adjusted either with respect to the fixed scale or with respect to a fixed index mark or an index mark on the follow-up member being adjusted with respect to the fixed scale. As shown in Figure 2, an exposure meter carried by or built into a camera has a rotatable disc 14 geared to a wheel 11 having a lug 11a engaging a pin 10, which bears on one end of a bell-crank lever 7, the other end of which bears on a pin 4. A spring 16 tends to turn wheel 11 anti-clockwise, so that pin 4 is urged into contact with a cam (not shown) connected to the diaphragm setting ring of the camera. For ordinary exposures, the shutter speed is set to a required value, and the diaphragm setting. ring is rotated until the disc 14 is brought to a position wherein the meter pointer 17 registers with the required shutter speed on the scale 18, with the aid of guide lines 50. The scale 18 is carried by a ring 24 rotatably connected to the disc 14 and carrying a scale of filter factors 21. The ring 24 is adjusted until the appropriate mark on scale 21 is brought opposite the appropriate mark on a scale 20 of film speeds on the disc 14. For flash exposures, the diaphragm is adjusted until the appropriate mark on a range scale 22 marked on ring 24, is brought opposite the appropriate mark on a scale 23 of flash power. Scale 23 is mounted on a fixed part of the camera, and may carry marks indicating types of flash bulb. A movable pointer may be adjusted between the scales 22, 23. The scales may be differently arranged as between the fixed and moving parts. In the form shown in Fig. 3, the disc 14 carries two movable rings 31, 33. The film speed scale 20 on disc 14 is visible through the cutout 31a in ring 31, and co-operates with the filter factor scale 21 on ring 33. An arm 37 on ring 33 has a pin 70 entering notches 14a in disc 14 to keep ring 33 and disc 14 in their relatively adjusted position. Ring 31 is rotated to bring the appropriate value on its flash power scale 23 opposite an index 35 of ring 33, and the disc 14 is then rotated together with rings 31, 33 to bring the appropriate value on the range scale 22 opposite an index 36 on the camera body. The scales and index marks may be interchanged if required.

Title: Improvements in the manufacture of catechin and catechu tannic acid
IPC: C14C3/10
Filed: 1920-03-24
Abstract: A process for the extraction of catechin and catechu-tannic acid from vegetable substances containing them consists in digesting the disintegrated raw material with hot water in the absence of air and preferably in an autoclave, filtering and concentrating the decoction, then cooling it in absence of air to allow the catechin to separate out, and finally evaporating the filtrate to dryness in absence of air and preferably in vacuo to obtain the catechu-tannic acid.  The precipitated catechin is purified by washing with cold water, and is then dried in the dark either by a current of hot air or by absorption of the p  contaminating liquid by means of sand contained in bags.  As starting material, the wood of acacia catechu or acacia sendra, and the leaves and shoots of uncaria gambier, are mentioned.

Abstract: 1,127,697. View and range-finders for photographic cameras. INTERNATIONAL POLAROID CORP. March 2, 1966 [March 15, 1965], No. 9150/66. Heading G2A. In a camera of the kind in which continuous focusing between a lens mounted on a lens board and the camera body is effected by a focusing bar 18 and a lazy tongs system between the board and the body, there is provided in a housing on the camera body a combined view-and range-finder, the latter being controlled by movement of the bar 18. The left half (as shown) of the housing contains the reversed Galilean view-finder system, light passing through lenses 30, 32 and semitransparent mirror 36 to the eyepiece 34. A fixed plate 28 and a movable plate 46 each have associated masking means 54, 52 which carry indications of the boundary of the scene to be photographed, and which each carry a reference mark, the marks and indications being reflected into the eyepiece by mirrors 38, 36. The opaque masks 54, 52 have transparent areas thereon. A transparent reference line 72 on fixed mask 54 is associated with a transparent rectangle 64 on the movable mask 52, so that as the latter is moved up and down due to movement of the bar 18, the line 72 remains visible and stationary in the view-finder as one of the reference marks. Light passing through a transparent rectangle 66 is reflected by a prism 82 wholly inside the movable plate 46 to the level 84 where it is reflected out of the plate to the eyepiece and forms a second, movable, reference mark. The system is arranged so that when an operator sees e. g. a human face, framed between the reference marks, the plane of the face is correctly focused at the camera film plane. The masks are provided with a scale 76 and mark 68 to indicate the range of the plane focused on the film. Narrow transparent rectangles 60, 58 interact to form a frame of diamonds visible in the view-finder and defining the boundary of the scene to be photographed. The position of these diamonds change as the focus is changed. The masks 54, 52 may be replaced by suitably patterned coatings on the plates 28,46.

Title: Preparation of an ester of 4-aminosalicylic acid with increased tuberculostatic effec
Filed: 1949-04-04
Abstract: The n-propyl ester of p-aminosalicylic acid, which has tuberculostatic properties, is manufactured by reacting p-amino- or p-nitrosalicylic acid or one of their esterifiable derivatives with propyl alcohol or a reactive derivative thereof (advantageously in an anhydrous solvent and in the presence of dehydrating agents, acid-binding agents, condensing agents or esterification catalysts), and, when starting from p-nitrosalicylic acid, subsequently reducing the nitro group to an amino group.  In an example, dry hydrogen chloride is passed into a heated solution of p-nitrosalicylic acid in propyl alcohol, and the resulting ester is reduced with hydrogen in ethyl acetate solution in the presence of Raney nickel.  The Specification as open to inspection under Sect. 91 comprises also the manufacture of other esters from acids of the general formula <FORM:0669061/IV (b)/1> (wherein R1 represents a free or substituted hydroxy group, a halogen atom, an amino, acyl, alkyl, aryl or aralkyl-amino group or a group convertible thereto, and R2 represents an amino, acylamino, alkylamino or arylamino group or a group convertible thereto), or functional derivatives of such acids suitable for the formation of esters, and aliphatic or carbocyclic compounds having more than two carbon atoms in the molecule and containing a primary, secondary or tertiary hydroxy group, or reactive derivatives thereof.  Additional examples describe the preparation of p-aminosalicylic acid phenyl and n-butyl esters, and reference is also made to 2-chloro-4-aminobenzoic acid allyl, lauryl, benzyl and guaiacyl esters.  Further hydroxy compounds specified are dodecyl and myricyl alcohols and menthol.  This subject-matter does not appear in the Specification as accepted.
