Title: Improvements relating to Photographic Apparatus
IPC: G03B13/20
Filed: 1967-09-01
Abstract: 1,173,935. Camera rangefinders. INTERNATIONAL POLAROID CORP. Sept. 1, 1967 [Sept. 6, 1966], No. 40044/67. Headings G2A and G2J. Rangefinding apparatus projects first and second beams of light which are angularly displaced to converge at a predetermined distance in front of the apparatus, said beams carrying information to identify each of them to an operator thus indicating whether the range of an object illuminated by the beams is greater or less than the predetermined distance. The angular displacement of the beams may be varied by the operator and the apparatus may be coupled to the focusing means in a photographic camera. A camera Fig. 2 has a lens turret 30 carrying three fixed-focus objectives 32a, 32b and 32c of differing focal lengths, each of which can be brought into the operative position by rotating the selector wheel 38. Rotation of wheel 38 also operates a cam 74 to alter the position of arms 79 and 80 and thus to move the mirrors 62 and 64 about the axes 66 and 70, light from a filament lamp 60 being reflected by the mirrors 62 and 64 and projected as two beams via lenses 63 and 65 to the subject, the lamp to mirror distance varying as the mirrors turn thus keeping each of the beams satisfactorily focused. To assist in identifying each beam, the beams may be differently coloured or of differing cross-section, or the filament lamp 60 and the lenses 63 and 65 may be so adjusted as to project a linear image of the filament in each beam, the angle of the filament being adjusted so that the axes of the images are at about 90 degrees to each other to provide a cross image at the spot where the two beams coincide. In operating the camera, the correct objective lens is selected by turning the selector wheel 38 until a setting is found where the two beams most nearly coincide at the subject.

Abstract: 1,161,539. Treating cellulosic materials. KURASHIKI BOSEKI K.K. 6 Sept., 1967 [6 Sept., 1966], No. 40784/67. Heading D1P. Cellulose textile materials, e.g. cotton or ramie fibres, yarns or fabrics are treated in a first step without tension with an aqueous alkali metal hydroxide solution of sufficiently high concentration to produce alkali cellulose II and then in a second step with an aqueous alkali metal hydroxide solution of sufficiently low concentration to produce alkali cellulose I. In the first step the textile material may be treated with an aqueous solution containing 25-35% by weight of caustic soda at 15-30‹C for 1-10 minutes and in the second step with an aqueous solution. containing about 10% by weight of caustic soda at 15-30‹C for 1-10 minutes. If the materials are treated in the second step without tension their stretchability, moisture absorption and dyeing capacities are improved and if the second step is effected with tension applied to the materials their lustre and strength are increased. The treated materials may subsequently be neutralized with an acetic acid solution, washed with water and dried. The materials may subsequently 'be treated with an aqueous solution of a melamine-formaldehyde precondensate containing an acid catalyst, centrifuged, dried and cured.

[Also in Division B2] A surface of a first substrate which is to be bonded to a second substrate by means of adhesive composition is prepared by subjecting the surface to ultra-violet radiation, and applying polyisocyanate. The first substrate comprises polymeric material having a critical surface tension of wetting of not more than 35 dynes per centimetre as determined by contact angle measurements, the polymer molecules of the polymeric material having at least one hydrogen atom on a carbon chain of a repeating unit of the polymer molecule. The polymeric material may be polyvinyl fluoride, polyvinylidene fluoride, polyethylene, polypropylene, or a copolymer of ethylene, propylene and a minor proportion of a non-conjugated diene, or a copolymer of isobutylene and isoprene. A photosensitizer, e.g. benzophenone, acetophenone and benzoin 2-acetonaphthone may be applied to the surface prior to the radiation step. A solution of polyisocyanate may be spread over the irradiated surface, and the excess wiped off. An adhesive composition may be applied to the surface after the radiation step and the application of polyisocyanate composition are completed. Alternatively, the polyisocyanate may be applied to the surface after the irradiation step in admixture with the adhesive composition. Examples of suitable adhesive compositions are solutions of linear polyester glycol urethanes, polyether glycol urethanes, linear polyesters. The adhesive composition may be heat or solvent sensitive. Substrates so prepared may then be bonded by pressing them together.
