Title: Telegraphic transmission of pictures and images
IPC: H04N7/00
Filed: 1924-01-15
Abstract: 233,746. Fournier d'Albe, E. E. Jan. 15, 1924. No Patent granted (Sealing fee not paid). Projection screens for receiving the image in a television system. The picture is reconstituted by reflection of light on to a screen from mirrors carried by tuned reeds on resonators h each tuned to a frequency which is characteristic of the position of the corresponding elemental area of the picture. Each resonator responds to its natural note when this is among the sounds, transmitted electrically, issuing from the loudspeaker s. The white screen i is blackened over areas covered by the lines of light reflected by the mirrors from the luminous line source L<2>, and the effect of the vibration of the mirrors is to produce luminous effects on the screen only where the lines of light are broadened out by the vibration. The intensity of each luminous effect is determined by the amplitude of the vibration. Alternatively the screen i may be perforated and placed in front of a ground glass screen viewed from the rear. In this case the intensity of illumination on the ground glass varies inversely with the amplitude of vibration of the corresponding reed.

Patent GB-700745-A (GB)
Title: Improvements in or relating to synthetic resinous products
Inventor: PHILLIPS LESLIE NATHAN
IPC: C08G65/36
Filed: 1950-01-18
Abstract: Resinous materials are produced by polymerizing a solution of a plurality of furane monomers and a thermoplastic resin component, the resin component being other than one based on a furane monomer and being capable of reacting or remaining dissolved when the solution is polymerized.  Specified furane monomers are furfuryl alcohol and aldehyde.  The resins include polyvinyl formal and butyral, polyvinyl acetate and lignin.  The solution may be stored for an indefinite time and is polymerized by adding an acid hardener, e.g. orthophosphoric acid.  This may be added in solution in, for example, methyl ethyl ketone, methylated spirit or furfuryl aldehyde itself. In the latter case, the solution of resin may contain only the furfuryl alcohol. If the proportion of alcohol to aldehyde is less than 2 or 3 to 1, the final product is soft; hard, tough products are obtained when the proportion is between 1 and 4 to 1.  The solutions containing hardener may be used to form water-repellant coatings and adhesives or sheets and moulded articles.  Felt and other materials may also be impregnated with the solution before or after adding the hardener.  Hardening is accelerated by heat, of the order of 85 DEG C.  Specification 625,847 is referred to.
