Title: Improvements in or relating to polarizing viewing screens
IPC: G02B5/30
Filed: 1942-10-01
Abstract: 570,983. Polarizers. INTERNATIONAL POLAROID CORPORATION. Oct. 1, 1942, No. 13783. Convention date, June 3. [Class 97 (i)] [Also in Group XXXII] A polarizing visor for use in a vehicle, which minimizes the effect of relative lateral tilting of the visor and the polarizing screen of the headlights viewed through it, is so formed and mounted that the orientation of the polarizing axis varies in a clockwise direction horizontally from left to right of the visor with respect to the driver and is substantially uniform in the vertical direction. The Figures show a visor in two positions of tilt due to road camber, the curved lines 12 representing the polarizing axes. The driver tends to maintain an upright position and so moves relatively to the visor in such a way that the oncoming lamps are seen in positions 30, 33 respectively to left and right of the centre of the visor ; in each case the tilt causes the polarizing axes 12 at the corresponding position of the visor to be substantially perpendicular to that of the polarizer of the approaching lamps. In a modification, the visor is divided into portions arranged side-by-side having their axes of polarization at different angles to the horizontal. The polarizer may comprise a suspension of oriented polarizing particles in a transparent medium, or a molecularly oriented plastic rendered dichroic as described in Specifications 548,759 or 549,698.

Patent GB-714752-A (GB)
Title: Cellulose ether compositions in the form of stable aqueous dispersions and method for producing the same
IPC: C08B11/20
Filed: 1950-06-02
Abstract: Stable aqueous colloidal dispersions of water-insoluble cellulose ethers (soluble only in 0.5-4 per cent. aqueous solutions of caustic alkali, i.e. of alkali metal or alkaline-earth metal hydroxides), contain no free caustic alkali and have a pH of 5-9.  The ethers may be prepared directly in the usual manner from cellulose or from low-substituted cellulose ethers soluble in 5-10 per cent. aqueous caustic alkali solution. After the ether has been produced in the usual manner in the presence of a caustic alkali, the dispersion may be prepared directly by neutralizing the remaining alkali with a dilute acid. In this case the cellulose ether dispersion contains an alkali-metal salt or an alkaline-earth metal salt.  Alternatively the ether may be separated from the dispersion thus formed by pouring the latter into a solution of a mineral acid, such as sulphuric acid having a pH not greater than 1, washing the precipitated ether with hot water until it is free from the salt of the acid and free acid, and drying.  The ether is then dissolved in 0.5-4.0 per cent. aqueous caustic alkali solution and the required amount of acid is added (with or without dilution with water) until the resulting colloidal solution has a pH of 5-9.  Instead of acids there may be used, for adjusting the pH of the colloidal solutions of the cellulose ethers, acid salts, ammonium salts, ethylene chlorohydrin or sodium chloroacetate.  In the example six parts of a hydroxyethyl cellulose containing 0.3-1.3 hydroxyethyl groups per anhydro-glucose residue (soluble in 0.4-4.0 per cent. aqueous sodium hydroxide solution at ordinary or subnormal temperatures and prepared in a described manner) are mixed with 60 parts of water and the mixture is stirred into 32 parts of water containing 2 parts of sodium hydroxide until the ether is completely dissolved.  Acetic acid is then gradually added until the mixture has a pH between 5 and 9.  Other cellulose ethers which may be used for the preparation of the dispersions are methyl or ethyl cellulose containing 0.5-1.3 methyl or ethyl groups per anhydro-glucose residue and carboxymethyl cellulose containing 0.05-0.8 carboxymethyl groups per anhydro-glucose residue. Dispersions for use as thickening agents for paints may be prepared by dissolving the ethers in 3 per cent. aqueous barium hydroxide and neutralizing the solution with sulphuric acid.  For use in flame-proofing compositions, solutions of the ethers in 0.5-4.0 per cent. aqueous sodium hydroxide solution may be neutralized by boric acid and subsequently heated with zinc sulphate.  Silica or sodium silicate may be added.  For use as water-proofing compositions, the dispersions prepared by dissolving the ethers in 0.5-4.0 per cent. aqueous sodium hydroxide solution may be neutralized with acetic acid and aluminium acetate then added.
