Filed: 1967-11-21
Abstract: 1,158,656. Vanadic acid. TREIBACHER CHEMISCHE WERKE A.G. 21 Nov., 1967 [6 Feb., 1967], No. 52849/67. Heading C1A. Vanadic acid with a low alkali metal content is produced by reacting vanadic acid having a sedimentation volume of less than 8 c.c. per gram of dry substance with a solution containing ions of one or more of the elements Mg, Ca, Sr, Ba, Ln, Sc, Y, Th, Zr, Hf, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Cd, Al and/or of ammonium whereby the alkali metal content is reduced by ion-exchange. The sedimentation volume in most cases is below 2.5 cc./g. of dry substance. The heavy vanadic acid is formed by precipitating from a vanadate solution at elevated temperatures exceeding 70‹ C. in a pH region between pH 1.4 and 2.0. Exchanger solutions of strength of at least 0.05 N should preferably be used particularly a strength of from 0À3 N to 3 N. The reaction temperature is above 20‹ C. A stationary bed of a "heavy" vanadic acid may be washed with the ion-exchange solution, or the solution may be continuously introduced to the reaction. The vanadic acid may also be continuously conveyed counter to the solution. A solution containing one or more ions of the alkaline earth metals and/or of aluminium can be used to produce a vanadium pentoxide containing those elements which can be used in metallurgy. The ion exchange solution may consist of vanadium ions having a valency less than 5. Instead of solutions of lower valency V-ions, solutions may also be used which form such ions by reaction with the vanadic acid that is to be washed. Examples are washing the vanadic acid with an acidified sulphite solution according to the equation V 2 O 5  + SO 3 <SP>2-</SP> + 4H<SP>+</SP> # VO<SP>2+</SP> + SO 4 <SP>2-</SP> + 2H 2 O or with an acid solution containing an organic reducing agent, for instance according to the equation V 2 O 5  + C 2 H 5 OH + 4H<SP>+</SP> # 2VO<SP>2-</SP> + CH 3 CHO + 3H 2 O.

Abstract: 1,178,099. Cathode-ray tubes. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 8 Nov., 1968 [11 Nov., 1967] No. 52982/68. Heading H1D. In a C.R.T. comprising a luminescent screen, an electron gun system and two coaxial circular cylindrical electrodes 70, 71 whose common axis does not coincide with the axis of an electron beam from the gun, the common boundary line between the two electrodes 70, 71 has, as shown, a profile so shaped as to be curved towards the screen on both sides of its point of intersection with a plane containing the cylinder and beam path axes, the point being adjacent the beam path axis. The common boundary line is the locus of the midpoint of the gap between the two cylinders if their ends are axially spaced or of the normal projection of the end of the smaller cylinder on to the larger one if they overlap. This shaping of the electrodes alters the focusing electric field to compensate for the different strengths of focusing experienced in the meridional and sagittal planes by an off-axis beam, and which causes astigmatism. As shown, the electron gun system may produce three off-axis beams, for colour television, which cross the plane containing the boundary line at 74, 75 and 76 respectively, in which case the shape of the development of the common boundary line is preferably sinusoidal. As shown, both adjacent ends of the electrodes 70, 71 may be so shaped; alternatively only the end of one of the electrodes may be shaped. In an example specific electrode dimensions and operating voltages are given. One, at least, of the cylindrical electrodes may be formed as a coating on the tube envelope.

Abstract: 1485877 Testing pulse regenerators SIEMENS AG 18 Dec 1974 [31 Jan 1974] 54804/74 Heading H4L The invention relates to an arrangement for locating faulty pulse regenerators in a P.C.M. transmission system of the type disclosed in Specification 1,212,908. In that Specification the fault detecting arrangements incorporate demodulators and associated band pass filters of different pass frequencies at respective intermediate stations of the system, together with arrangements for transmitting from an end exchange a pulse train consisting of code elements modulated such that the frequency of the envelope curve corresponds to the pass frequency of the band pass filter at a particular station to be tested. The present invention is concerned with the means for producing the test pulse pattern. The test pulse pattern generator comprises a fundamental pulse pattern generator 22 whose pattern bit rate corresponds to the normal data flow and contains a sync. signal consisting of pairs of code elements 11 and 00 arranged in alternating sequence and spaced by other code elements. The generator also comprises a binary counter 21 and switches 19 for setting the counter to a selected numerical value (corresponding to the regenerator to be tested). In operation the counter counts from the set value to a final value. A low frequency rectangular waveform generator 24 is responsive to the counter reaching the final value and produces a frequency (corresponding to the pass frequency of the filter in the selected regenerator) which modulates the fundamental pulse pattern. A pulse generator 23 supplies control pulses to the fundamental pulse pattern generator, the counter and the rectangular waveform generator. The rectangular waveform is arranged by switching to have either a mark/space ratio of 1 : 1 or other than 1 : 1. A switch 27 and gate 25 are provided for gating "fault" pulses into the pulse pattern.
