Abstract: Ethyl toluenes are prepared by (a) reacting toluene with 0.4-1.1 mol. of ethylene in the presence of aluminium chloride at 50-90 DEG  C., (b) fractionating the product from (a) to obtain toluene, ethyltoluenes and diethyltoluenes, (c) disproportionating the diethyltoluenes from (b) in the presence of toluene and aluminium chloride at not more than 90 DEG  C., (d) fractionating the product from (c) to obtain toluene, ethyltoluenes and diethyltoluenes and (e) combining the ethyltoluenes from (b) and (d) to obtain over head a fraction containing at least 30% of para isomer; the amount of aluminium chloride used in steps (a) and (c) being 0.5-3.5% by weight of total hydrocarbon.  The bottoms from step (e) contain a high proportion of ortho-isomer and may be isomerized in the presence of aluminium chloride at nor more than 90 DEG  C., ethyltoluenes separated from any toluene and diethyltoluenes formed and redistilled in step (e).  Iso- and tere-phthalic acids may be prepared by oxidation of the overhead mixture of paraand meta-ethyltoluenes from the final fractionation.

Title: Improvements in and relating to indirectly-heated cathodes
IPC: H01J1/22
Filed: 1960-04-19
Abstract: 923,183. Thermionic cathodes. EITELMcCULLOUGH Inc. April 19, 1960 [July 16, 1959], No. 13666/60. Class 39 (1). [Also in Group XI] In an electron tube comprising an indirectlyheated cathode 11, the heating filament 17 is caused to emit electrons and a time decreasing voltage is applied between the filament and cathode to cause time decreasing electron bombardment of the cathode, whereby the cathode is quickly raised to its emissive temperature. The filament may be a helix of thoriated tungsten or tungsten, with a carburized coating, arranged in a cylindrical cathode cup, Fig. 1 (not shown). As shown, a capacitor 23 is connected between filament and cathode, and is charged from a D.C. voltage source through a resistor 24 at a rate which approximates the rate at which the cathode loses heat during a cooling cycle, so that switch 31 may be omitted. Initially, switch 29 is in the position shown so that a relatively high voltage is applied across filament 17 causing electron emission. After 0.25 secs. the filament heating voltage is reduced, by movement of switch 29, to a value sufficient to maintain cathode 11 at its operating temperature, electron emission from the filament gradually ceasing.

Abstract: 632,365. Sawtooth generating circuits. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. May 11, 1946, No. 14266. Convention date, May 11, 1945. [Class 40 (vi)] In an electromagnetic deflecting system for a cathode-ray tube the steady potential produced by a damping rectifier is used to assist the supply source and the impedance of the rectifier is varied in such a manner as to linearize the scanning of the tube. The Figure shows an arrangement for line deflection of a C.R. tube in which the rectifying valve V2 is connected to the secondary of output transformer Tr, in series with capacitor C<1>, so that a D.C. voltage appears across the latter with a polarity assisting the D.C. supply EB1. As the transformer ratio is fixed by the need for the steady secondary current to equal that from EB1, deflector coils LH are fed from a matching tap N2 through a blocking capacitor. A choke-resistor arrangement is provided for applying D.C. centring potentials. The choke may be replaced by a winding wound parallel (i.e. two wires at a time) with part of the secondary, Fig. 9a (not shown). The grid voltage waveform of V2 is derived from resistorcapacitor network and is such that the net deflector coil current is a linear sawtooth. The D.C. voltage may be fed back in parallel with EB1, if a suitable transformer ratio is selected. Reference has been directed by the Comptroller to Specification 588,620.
