    Abstract: A radiation-excited light source having a beta-emitting radioisotope within a sealed tube. Illumination is provided by the impingement of betas upon phosphor material within the tube. ''''Fiber optic'''' light transmission media are affixed longitudinally along the exterior of the tube and feed light to a plurality of display locations. In one embodiment a thin layer of phosphor is coated over the entire inner surface of the tube. In another embodiment a thicker layer of phosphor is coated to a metal shell positioned within the tube.

    Abstract: A radiation excited self-luminous light source in which luminescence is provided by the impingement of beta emissions upon a phosphor within the source. A gastight chamber within the source is bounded by a concave phosphor surface and by radiationresistant window. The concave surface is of a predetermined shape designed to maximize the efficiency of the source. In addition, the gastight chamber is designed to withstand pressures of up to 15 atmospheres, thereby enabling gaseous radioisotopes of greater activity to be utilized as the source of beta emissions. In one embodiment, greater efficiency is achieved by utilizing a window having a convex surface which corresponds to the concave phosphor surface and which is positioned a predetermined distance from the phosphor surface equal to the average range of beta emissions within the chamber.

    Abstract: 1,173,080. Photo-electric pressure measurement. AMERICAN ATOMICS CORP. Dec. 5, 1967 [Dec.5, 1966], No.55341/67. Heading G1A. In a pressure measuring arrangement a source of radiation is coupled to a flexible diaphragm or bellows subjected to the pressure to be measured whereby the spacing between the source and a radiation detector varies according to pressure. The radiation may be light, infrared # or γ rays or ultrasonic vibrations. In Fig. 1 a fluid whose pressure is to be measured enters a chamber 2 via a port 10 to flex the diaphragm 6 subjected on its other side to a reference pressure, such as atmospheric. A source of radiation 20 is coupled to the diaphragm by a rod 15, whose position relative to the radiation detector 21 is thereby varied. The source in Fig. 1 is a radio-actively excited scintillator. The diaphragm may be replaced by bellows Figs.2 & 3, (not shown).
