Title: Cathode ray tube having index strip electrode
IPC: H04N9/077
Filed: 1972-05-26
Abstract: 1376220 Colour television MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd 26 May 1972 [26 May 1971 28 April 1972] 24954/72 Heading H4F [Also in Division H1] A colour television tube comprises index strips 70, Fig. 6, at the top or bottom of the main screen area, and start and stop strips 71 and 71<SP>1</SP> at the sides. In the display system shown in Fig. 8, bright-up pulses from generators 90 and 98 are fed to the electron gun at the start of each frame and line whilst the index strips and the start strips are being scanned, and the index signal is fed through amplifier 84 to a waveshaper 85, which removes high-frequency components, and to a memory 86. Signals regenerated from the memory 86 are compared with signals from a reference oscillator 89 operating at index frequency to derive a correction signal which is fed via amplifier 83 to auxiliary horizontal deflection plates 68 to correct the scanning speed of the beam which is scanned horizontally and vertically by the yoke 67 in response to waveforms initiated by pulse generators 81 and 80 respectively. The start signal from the index strip triggers a gate pulse generator 92 which gates (93) the green colour signal through to the intensity control unit 91 controlling the electron gun 66. The blue and red signals pass through similar gates 95, 97 controlled by delayed versions of the same gate signal. In the transmitting system shown in Fig. 20 the start pulses are selected by the first gate 120 controlled by the horizontal deflection pulse generator 118; a detector 121 produces a voltage proportional to the period of the start pulses, and this is used to modulate the amplitude of the horizontal deflection voltage from generator. 123. Index signals are fed through a second gate 126 to a memory 127 from which regenerated signals are compared with signals from a reference generator 128, and the output of the discriminator 129 is used to control the frequency of an oscillator 131 operating at three times the colour frequency; this feeds a 3-stage ring counter 132 controlling respective gates 133-135 which select the three colour signals for use in the encoder 136 which produces a composite colour video signal of desired form. In a modification (Fig. 23, not shown) colour signals are selected from the tube output by means of a filter and mixed with index signals; after filtering, the mixed signal is mixed with the image signal from the tube and fed to a third filter operating at index frequency which supplies inputs to three synchronous detectors operating at index frequency which provide the required three colour output signals to the encoder unit. The output of the third filter supplies the luminance signal to the encoder. As described the index electrode is conductive, but it may alternatively be secondary electron emissive or luminescent.

Filed: 1965-06-15
Abstract: Finely divided metalliferous powders composed predominantly of metal oxides, metal carbides, free metals or mixtures thereof are produced by distributing heat convertible compounds of the corresponding metals together with a lesser amount by weight of carbon black throughout a volatile liquid medium, spraying the resultant dispersion through a heated zone to evaporate the volatile liquid and produce dried, fine particles of the metal compound in association with carbon black, and thermally treating the particles to obtain the required product.  Possible starting materials are heat convertible compounds of Cu, Zn, Pb, Sn, Fe, Co, Ni, W, Mo, Al, Zr, Ti, Cr, B, Si, Ta, Ba, Mn, Th, Hf, U and Nb with sulphates, chlorides, bromides, iodides, fluorides, nitrates, perchlorates, sulphides, acetates, citrates, oxalates, formates, benzoates, carbonates, and tartrates preferred.  The product may contain residual carbon which can be removed by oxidation or steam treatment.  Alternatively, for certain purposes the product may contain up to 90% residual carbon. Carbon-free metals may be produced by using slightly less than the stoichiometric amount of carbon black and treating the product in a reducing atmosphere to reduce any minor amounts of oxides still present.  The production of nickel oxide, nickel ferrite, nickel dispersion-strengthened with alumina, iron titanium dioxide, nickel-nickel oxide, ferro-molybdenum, ferro-tungsten, aluminium carbide and tungsten carbide is specifically described.ALSO:Finely divided metal oxides or metal carbides are produced by distributing heat-convertible compounds of the corresponding metals together with a lesser amount by weight of carbon black throughout a volatile liquid medium, spraying the resultant dispersion through a heated zone to evaporate the volatile liquid and produce dried, fine particles of the metal compound in association with carbon black, and thermally treating the particles to obtain the required product.

Filed: 1970-05-26
Abstract: 1315321 Well-logging SCHLUMBERGER INLAND SERVICES Inc 26 May 1970 [26 May 1969] 25195/70 Heading H4D In a well-logging system rotary scans of the well wall are made by a well tool having an energy transmitting - receiving transducer arrangment, data derived from signals representing the transmitted and reflected energy are recorded as a function of the tool depth, and an amplitude detector measures the maximum or minimum amplitude level of said signals occurring in a given time period. In the Fig. 1 embodiment acoustic pulses So are transmitted periodically by a directional transducer 22 rotated at constant speed by motor 20 and reflection pulses Sx are amplitudecorrected at 51 (using the So pulses as a reference) to compensate for factors tending to disturb the amplitude of both So and Sx pulses. The peak amplitude of the corrected pulses occurring in a period corresponding approximately or exactly to one 360 degree scan of the transducer 22 is determined at 53 as an indication of the well wall acoustic impedance, e.g. to indicate the lithology of an uncased well wall. The peak detecting circuit (details given) has a fast attack time (though slow enough to prevent occasional noise pulses from affecting the measurement) and either (a) is reset once per 360 degrees scan by a pulse from a magnetometer assembly 23 rotated with the transducer 22 or (b) has a decay time slightly greater than the time for a 360 degree scan. The measured peak amplitude is recorded at 46 (e.g. by a recording galvanometer). The time interval between each S o  pulse and its echo S x  ismeasured at 53 by a gated current-integrator (details given, Fig. 4, not shown), and over a 360 degree scan of the transducer the maximum, minimum and average values of these time intervals are determined (Fig. 4, not shown) at 53 and recorded at 46 as indicative of the maximum, minimum and average diameter respectively of the well. A record is also provided at 46 of occasions when echo signals are not detected, to indicate a possible faulty measurement of well diameter.

Title: Process for the production of trialkyl benzenes
IPC: C07C2/68
Filed: 1956-08-21
Abstract: Trialkylbenzenes are prepared by alkylating a xylene with ethylene or propylene in the presence of 0,005-0,25 mol. of aluminium chloride per mol. of xylene at 50 to 150 DEG C. the mol. ratio of total alkyl reactants (alkene plus alkyl groups on the benzene nuclei) to benzene nuclei being 2,6 to 3,5:1, separating trialkylbenzenes from the product mixture and recycling higher and lower alkyl benzenes to the reaction.  The trialkyl benzenes are useful as precursors for benzene tricarboxylic acids which are formed by oxidation.  Reaction times of 0,1-10 hours may be used.  Conditions are chosen so that the weight ratio of trialkylbenzenes to higher alkylbenzenes is at least 1:1. In a typical example, a mixture of xylenes is ethylated at 70-100 DEG C. for 40 minutes using an alkyl/benzene ratio of 2,78:1. Trialkylbenzene are separated by distillation and oxidised with air in the presence of cobalt acetate, manganese acetate, ammonium bromide and hydrobromic acid in acetic acid, at 400 p.s.i.g. and 196-210 DEG C. and the tribasic acids so formed crystallised from glacial acetic acid.
