Abstract: This disclosure is directed to a highly efficient linear polarizer which is effective to separate normally incident light thereon into two oppositely polarized components, one of which is transmitted and another component which is reflected.

Abstract: 1,105,516. Vehicle - anti dazzle screens. INTERNATIONAL POLAROID CORPORATION. 9 March, 1965 [9 March, 1964], No. 9960/65. Heading B7J. [Also in Divisions E1, F4, G1 and G2] A windscreen comprises a light filter which comprises (Fig. 1) a sheet of material 4 (e.g. a molecularly orientated polyvinyl alcohol), which may alternately be rendered polarizing and non-polarizing by staining and deataining respectively, and which has a protective non- staining back 5 on one surface, electrodes 2, 3 (e.g. of electrically conducting glass), and an electrolyte 6 which contains ions which stain material 4. On passing an electric current, sheet 4 is rendered polarizing or non-polarizing depending on the direction of the current, which may be controlled by a switch 11 or by a photoelectric cell 13 which is actuated by headlamps of on-coming vehicles. The sheet is arranged so that its axis of polarization is 45 degrees to the vertical and is used in conjunction with polarizing headlamps with a parallel axis of polarization, so that glare from the lamps of a similarly fitted vehicle is eliminated. Cells similar to that of Fig. 1 which contain two sheets of materials 4, at least one of which may be rendered non-polarizing may be used (Figs. 2-5, not shown); the axis of polarization of the second sheet may be vertical to reduce glare from sunlight reflected off the road.
