Abstract: 1376926 Matrix displays SIEMENS AG 26 Nov 1971 [26 Jan 1971] 54912/71 Heading G5C [Also in Divisions H3-H5] A display screen comprises a support layer formed of solid transparent material, which layer is of substantially constant thickness and is provided with a plurality of interstices filled with nematic liquid crystal material. The interstices may be such that the nematic material is directly absorbed thereby. Alternatively the interstices may be closed and dispersed throughout the support layer, e.g. as when the layer is produced by mixing the nematic material with a settable liquid supporting material, and allowing it to set. Suitable supporting materials are gelatine, cellulose derivatives, polyvinyl alcohol, and a mixture of collodium and butyl acetate or of nitrocellulose and amyl acetate. Preferably the material has a resistance such that most of a D.C. voltage applied across the screen is applied across the nematic material. In a third embodiment, the interstices are depressions in one side. of a support layer, or holes extending between both sides of the layer, and are closed by a transparent sheet or sheets on one or both sides of the layer. In a further embodiment the support layer comprises two transparent spaced layers welded or otherwise joined at points or along a plurality of lines to form the interstices. As particularly described, the nematic material exhibits the dynamic scattering effect, and for this purpose electrodes are provided, e.g. in contact with the liquid crystal material for a D.C. field or isolated therefrom for an A.C. field. The electrodes may be X and Y addressing strips.

Abstract: 1,146,134. Lamp failure alarms. J. B. RAMSEY. 12 Dec., 1967, No. 56416/67. Heading G4N. [Also in Division H2] In an automobile lighting system having first and second lamp circuits drawing different currents, one circuit is connected in series with one winding of a double-wound relay whilst the other circuit is connected in series with both windings, the relay being arranged to be normally energized, but provided with means to energize both lighting circuits if the relay becomes released by failure of one or more lamps. As shown, the head lamps have high and low beam filaments 22, 23 selected by means of a floor switch 32. The high beam filaments are connected in series with winding K2 of a relay S1 whilst the low beam filaments 23 are connected in series with both windings K1 and K2. The relay is arranged to be just energized when normal current is taken by either set of filaments, but releases in the event of failure of one or more filaments, energizing both beams via dimming resistors 74, 81. This prevents the complete loss of head lamps on either side of the vehicle. A further relay S2 provides similar protection for the rear lamps 87, 88, winding K3 being tapped to accommodate 2, 4 or 6 rear lamps. Indicators 80, 92 become illuminated when respective relays S1, S2 are energized by lamp failure. The relay unit 40 has provision (Figs. 1, 4, 5, 6, not shown) for being plugged into the existing wiring harness. Socket 63 may be reversed when the relay unit 40 is being used on a vehicle having four head lamps in which case the windings K1 and K2 are connected in series opposition with the high beam filaments.
