Реферат: 2954. Spooner, A. F., [VÚry, H.]. Feb. 7. Letters; signs.-Luminous signs are formed hollow by blowing or moulding glass or other transparent or translucent material. Reflectors b are fitted at the back, and the whole is secured in a frame h. The electric lamp e or other source of light is inserted through the aperture d. A transparent screen of unpolished glass or other material is inserted between the lamp and the front to disperse the light. The letters a constituting the sign may be roughened to give them a white appearance in the day time, and the intervening parts c maybe painted. The signs may have eyes j for suspension, or they may be attached by screws to a backing.
