Abstract: 1433333 Viewing apparatus FIDELITY INSTRUMENT CO Ltd 2 May 1973 [17 May 1972]  23165/72 Heading G2J [Also in Division H4] A binocular viewing device comprises means (e.g. prism 11, objective 17 and image intensifier 18) for providing an original luminous image on a surface 19 and at least two reflecting surfaces 22, 23 one of which is concave to focus at infinity a final image of the luminous image. The optical paths 25, 26, 27 lie substantially wholly within solid or liquid or partially solid and partially liquid media. In one embodiment, Fig. 1, an electro-optical periscope comprises a pentaprism 11 which directs light through an objective 17 and image intensifier 18 to form an image on cathode ray screen 19 attached to a prism 20. Prism 20 has a spherical, concave, reflecting face 22, which forms an image of the screen 19 at infinity, and a plane reflecting face 23 from which light leaves the prism to pass through a corrector plate 24 to both eyes of the observer. In a modification, Fig. 2, the prism 31 has two spherical reflecting faces 33, 34 and a semitransparent mirror 32. In another modification (not shown) of Fig. 1, the pentaprism is replaced by a triangular prism and prism 21 is provided with two plane mirror surfaces to give the correct image inversions. In yet another modification (not shown) the pentaprism is replaced by a roof prism and a sandwich of a photocathode, a channel plate and a cathodoluminescent screen replaces the intensifier 18. In a further embodiment, Fig. 3B, a line-ofsight image intensifier comprises an objective (not shown) which forms images on the photocathode of an intensifier 41 whose screen 46 is attached to a composite prism 43 of the form shown, wherein the spherical reflecting face 48 produces an image at infinity of screen 46. Another line-of-sight intensifier, Fig. 4A, comprises a fibre-optic bundle 64 between the screen 63 and prism 66 having a spherical reflecting face 67. Yet another line-of-sight intensifier, Fig. 5B, comprises a prism 71 having a plane reflecting face 72 and two spherical silvered surfaces 73, 74.

Title: Manufacture of polyvinyl alcohol fibres
IPC: D01F6/14
Filed: 1958-07-21
Abstract: Polyvinyl alcohol fibres having a low degree of shrinkage are made by impregnating heattreated polyvinyl alcohol fibres in the form of endless filament, sliver or staple fibres at room temperature or below with an acid, salt-containing formaldehyde bath, squeezing or centrifuging off excess hardening liquor and then heating the fibres in a pressure vessel or in a tube in a loose state to a temperature of 50 DEG -100 DEG C. until, after washing out the hardening bath, their shrinkage in boiling water amounts to no more than 10%.  When a sliver is treated it may be impregnated with the hardening bath, squeezed out and then cut into staple fibres prior to heating. Heating may be carried out in a closed vessel for 10-120 minutes. When the process is carried out in a continuous manner the impregnated sliver may be conducted in a loose state through a tube through which a current of hot air containing steam and having a temperature of 90 DEG -100 DEG C. is passed.  In a modification of the process the fibres are impregnated with an acid, salt-containing bath which does not contain formaldehyde, excess of the bath is squeezed or centrifuged off and the fibres are then heated in a pressure vessel or tube in which the amount of formaldehyde necessary for the hardening process is volatilized in the presence of steam at a temperature of 50 DEG -100 DEG C. or into which the necessary amount of formaldehyde is introduced in the gaseous state at 50 DEG -100 DEG C. until, after washing out, the shrinkage of the fibres in boiling water amounts to no more than 10%.  In the manufacture of crimped staple fibres the sliver may be cut and crimped prior to impregnation with the hardening bath or after hardening and washing.

Title: Improvements in and relating to the preparation of titanium compounds
IPC: C01G23/00
Filed: 1931-08-25
Abstract: Basic titanium sulphate is obtained by hydrolysis of tetravalent titanium solutions containing mainly chloride but also not less than about 0,13 mols. SO3 to 1 mol. TiO2 and preferably not more than 0,25 mols. SO3 to 1 mol. TiO2.  Hydrolysis is effected above 70 DEG  C. and extenders such as barium sulphate may be present.  The solutions to be hydrolysed may be obtained by adding sulphuric acid or a soluble sulphate to a chloride solution, or by dissolving a basic titanium sulphate in hydrochloric acid, or by dissolving titanium sodium sulphate or titanyl sulphate in hydrochloric acid and removing excess sulphate by adding a barium chloride solution, or by precipitating part of the sulphate from a sulphate solution by alkaline-earth chloride, or by adding hydrochloric acid or a chloride such as sodium chloride giving a soluble sulphate to solutions containing only a moderate amount of sulphate. Extenders may be added to the solution as such or be precipitated therein either before or together with the basic sulphate, or be added after precipitation. For use as pigments the products are washed, dried, and ingited.  The mother liquor from the precipitation process, after removal of any remaining titanium, may be neutralized with an alkaline-earth hydroxide, sulphide, or carbonate to precipitate impurities and obtain a solution of alkaline-earth chloride which may be returned to the process.
