Title: Radiation ratemeter
IPC: H01J47/04
Filed: 1961-03-22
Abstract: 950,559. Radiation rate meters. BENDIX CORPORATION. March 22,1961 [March 30, 1960] No.10481/61. Heading G1Q. A radiation rate meter has two electrometer elements under potentials of common polarity, in an ionization chamber, so arranged that the supply of charges from the potential source to at least one element is limited to less than the supply of charges of opposite polarity from the ions produced in the chamber by the radiation, whereby the relative deflection of the electrometer elements is a measure of the rate or intensity of the radiation. In Fig. 2, when a roll type capacitor 38, is charged to say, +150V, by an external source applied to pin 54, a fixed frame 46 and a high resistance electrometer fibre 50 are charged and mutually repel producing maximum deflection of the fibre. This is read, through a microscope 26, 30, against a scale 28, calibrated in rontgens/hour and corresponds to zero radiation. When radiation ionizes the air in the ionization chamber 34 both electrometer elements 46, 50 attract electrons and a current flows therein. Owing to the high resistance of the fibre a potential drop occurs from the centre towards each end of the fibre, the centre point voltage falling in proportion to current flow. The fibre therefore moves towards the frame in accordance with the rate or intensity of ionizing radiation, the deflection/radiation relationship being substantially logarithmic. In another embodiment, Fig. 5, two fibres one, 60, of high resistance and another,62, of very low resistance are attached to the frame 64. The deflection between frame 64 and fibre 62 varies only with the charge on capacitor 38 and may be used for indicating the state of discharge of capacitor 38 and for correcting the reading of fibre 60 which functions similarly to the fibre 50, Fig. 2. In a further embodiment, Fig. 7 (not shown) the condenser discharge indicator fibre 62 and the ratemeter indicating fibre 60 are mounted in separate barrels, the capacitors 38 of each barrel being paralleled. In another embodiment, Fig. 8 (not shown), discharge of the capacitor energizing the ratemeter chamber is compensated by the capacitor discharge of a second ionisation chamber. The frame and fibre have relatively low resistance and are supported by a resistive collar in contact with one plate of the capacitor in a further embodiment Fig. 9 (not shown). Here a pushbutton switch by-passes the collar, and the zero point or full charge on the capacitor can be indicated. In further embodiments the frame and fibre are charged by an alpha particle source e.g. polonium, Fig. 10 (not shown), or by a solid ion, or other battery directly connected to the frame Fig. 11, (not shown) Specification 950,560 is referred to.

Title: Improvements in or relating to the manufacture of aliphatic diesters of aromatic dicarboxylic acids
IPC: C07C69/80
Filed: 1947-04-21
Abstract: Aliphatic diesters of aromatic dicarboxylic acids are obtained on heating, e.g. at 100-140 DEG  C., an aliphatic monoester of the acid with an aliphatic hydroxy compound, distilling off water produced together with unchanged hydroxy compound, adding additional hydroxy compound to the reagents and distilling and continuing the process until the distillate is substantially free from water.  It is preferred that acidic catalysts such as sulphuric acid and alkali metal bisulphates be present and that the hydroxy compound be slowly added to the reaction mixture in order that the maximum amount of water is removed therewith.  In a modification the acid or its anhydride is heated with 2-3 mols. of the hydroxy compound, the monoester first formed being converted in situ to the diester by the above process.  Acids specified are phthalic acid and hydrogenated phthalic, e.g. di- and tetra-hydrophthalic acids and hydroxy compounds specified are methanol, ethanol, the propanols, normal and secondary butanols and glycol ethers, e.g. ethylene glycol monomethyl ether. In examples: (1) mono-methyl-, (2) mono-n-butyl and (3) mono-(methoxy-ethyl)-phthalate obtained by heating the appropriate hydroxy compound with phthalic acid in the presence of a small proportion of sulphuric acid are converted without isolation into the corresponding diester.
