Title: Improvements in or relating to electric transfer circuits
Inventor: MANSFORD HUGH LYON
IPC: G01R13/26
Filed: 1956-04-06
Abstract: 857,539. Television. ELECTRIC & MUSICAL INDUSTRIES Ltd. April 5, 1957 [April 6, 1956], No. 10520/56. Class 40(3). [Also in Group XL(c)] Relates to a circuit for transferring to a load, in the absence of a D.C. coupling, signals including both A.C. and D.C. components. The invention is stated to be of general application, reference being made to television systems and oscilloscopes, but is described solely in relation to a circuit for applying a brightening pulse to the cathode of the display tube of an oscilloscope. The pulse 20 appears on lead 1 from a low impedance source, such as a cathode follower, and is applied to the cathode 11 by way of an A.C. coupling so that the pulse source is isolated from the large D.C. potential required for operation of the tube. The coupling consists of a first path including capacitor 2 which transmits only the high-frequency components of the pulse, and a second path including a 5 for transmitting the D.C. and low-frequency components of the pulse. In this second path the pulse components are modulated in a stage 3 on a carrier, e.g. of 100 kc/s, provided by oscillator 4 and after passage through the transformer are reproduced by demodulation in a bi-phase rectifier 6 and 7. The sense of the modulation is such that the pulses reduce the carrier amplitude. The pulse components appearing across the rectifier load 9 are then added via resistor 10 to those appearing through capacitor 2 and applied to the tube cathode. In accordance with a feature of the invention, capacitor 2 functions to decouple the carrier components in the output of the rectifier circuit via the low impedance of the pulse source. Capacitors 14, 18 and 19 provide normal decoupling of the respective points in the circuit to earth. Resistor 15 permits the gridcathode bias of the tube to be varied. The part of potentiometer 17 connected between the tube cathode and the slides appears as a shunt load to the signal applied to the cathode, and where the potentiometer is arranged remote from the tube a resistor is preferably included in the cathode lead to isolate the shunt capacitance. Specification 696,362 is referred to.

Title: Braun tube and a method of producing the same with controlled light intensity
IPC: H01J29/82
Filed: 1934-04-07
Abstract: 438,117. Cathode-ray tubes. HUDEC, E., 38, Kirchweg, Nikolassee, Berlin. April 7, 1934, No. 10532. Convention date, April 8, 1933. [Class 39 (i)] The invention relates to Braun tubes with light intensity control, in which the electrodes are supported from two parallel glass holding rods 6 sealed to the pinch 7 in a manner already known in itself. To avoid distortion of the electrode structure by stresses introduced in sealing metal supporting wires to the holding rods, the wires are, according to the invention, replaced by short glass rods sealed to the electrodes. The short glass rods may be sealed to short rods of a metal which seals easily to glass, which are in turn welded to the electrodes. A glass of low melting point such as lead glass is preferably employed. The electrodes are assembled in exact axial alignment by means of a centring gauge provided with easily removable distance pieces which engage the various electrodes. To test the accuracy of the alignment when the gauge has been removed, the electrode assembly is, in a known way, mounted in a frame which is rotated, so that any eccentricity may be detected visually.

Patent GB-808055-A (GB)
Title: Aluminium trialkyls and alcohols prepared therefrom
IPC: C08F10/00
Filed: 1957-04-05
Abstract: Aluminium trialkyls, containing 12 or more carbon atoms in the molecule are prepared by contacting ethylene at elevated temperatures and pressures with an aluminium trialkyl, containing at least one branched chain alkyl radical having a C1 to C4 alkyl radical attached to the b -carbon atom thereof. The higher molecular weight aluminium alkyls are oxidized by contacting them with an oxygen-containing gas, preferably air, to give the corresponding aluminium alcoholates which are hydrolysed to the corresponding alcohols.  The aluminium trialkyl used as starting material may be reacted with ethylene at temperatures, for example, of from 80 DEG  to 125 DEG  C. and pressures of 200 to 5000 p.s.i.g.  The aluminium trialkyls so obtained are oxidized preferably by bubbling an oxygen-containing gas at 0 to 500 p.s.i.g. and 0-90 DEG  C. through them to give the corresponding alcoholates.  The aluminium alcoholates may be diluted with a liquid paraffin such as n-hexane or heptane or an aromatic hydrocarbon such as benzene or toluene before submitting them to hydrolysis by treating them with an aqueous solution of HCl, H2SO4, HNO3, NaOH, KOH or of an organic acid or base or with steam at elevated temperatures.  In the example ethylene is pumped into aluminium tri-isobutyl and the mixture is maintained at elevated temperature and pressure for 3 1/2 hours; the aluminium trialkyl product is then oxidized by bubbling air through at 80 DEG  C.; the aluminium alcoholate so obtained is diluted with n-hexane and treated with dilute hydrochloric acid to give straight-chain alcohols, mainly C10 to C14 with some lower alcohols.
