Abstract: 1,016,898. Fumaric acid. HALCON INTERNATIONAL Inc. Oct. 26, 1962 [Nov. 8, 1961], No. 40572/62. Heading C2C. Fumaric acid is made by isomerizing aqueous maleic acid of at least 10% weight concentration in the presence of a known isomerization catalyst, e.g. as disclosed in Specification 958,694, especially a water-soluble bromide and persulphate, above the minimum isomerization temperature and adding to the solution additional maleic acid solution below the minimum isomerization temperature, the rate of addition being such that the resulting mixture is maintained above the minimum isomerization temperature. Preferably 15 to 30% of the 10% aqueous solution and isomerization catalyst are brought to 70‹ to 80‹ C. and the remainder of the aqueous solution at not above 50 degrees is added thereto at such a rate that the temperature does exceed 50‹ C. The catalyst may all be added to the initial solution, or dosed progressively. The maleic acid solution may be obtained as scrubber liquor from scrubbing effluent gas from a maleic anhydride process. The examples, which include a comparative run, wherein the total solution is isomerized as one batch, describes the use of ammonium bromide/ persulphate mixtures.

Abstract: 1,052,372. Monogrammic signs. W. G. MITCHELL. Aug. 27, 1964 [May 28, 1963], No. 21361/63. Heading G5C. Individual light bulbs in a display array are selectively energized by selectively illuminating corresponding light-sensitive cells. Fig. 3 (not shown) illustrates punched cards or photographic negatives (12), movable to interrupt light from a source (11) so as to illuminate selected cells of an array (10). The cells may'be photo-sensitive resistors (Fig. 1, not shown) or photo-transistors 8 (Fig. 2). and each controls a relay 5. Relay 5 may be mechanical, as shown, or may be a transistor or silicon controlled rectifier, and serves to control current to a pair of bulbs 1, 2. Bulbs 1 are white and form the display array; bulbs 2 form a corresponding array but situated in the control room. Bulbs 1 are conveniently arranged on panels (Fig. 4, not shown), which are mounted on catwalks and may form a display covering the whole side of a building, bulbs 1 forming vertical columns which diverge towards the top of the building to off-set the effect of perspective. The panels may have rear members, carrying bulbs 1 to project through recessed apertures forming reflectors in the front members, both members normally standing well off the wall of the building, but sliding back, independently, for maintenance. The white bulbs 1 may be supplemented by additional coloured bulbs, these being controlled in groups by a drum bearing contacts coacting with pick-up brushes, and arranged in rows between rows of white bulbs. Successive frames (12) (Fig. 3) may be fed to produce a moving display.

[Also in Division H1] In dielectric amplifiers and frequency modulated oscillators temperature stabilization is effected by mounting the dielectric in thermal contact with another dielectric body maintained in an autostabilized mode by dielectric heating as described in Specification 1,049,613. In the oscillator shown in Fig. 3 the temperature of body 1, forming part of the resonant circuit, is maintained by the dielectric heating of body 2 at the temperature at which the dielectric constant of body 1 varies most with applied voltage. Modulation is effected by a signal applied at 9. In the amplifier of Fig. 4 the bodies 11, 12 form a tuned circuit with inductor 7. Again they are maintained at a temperature at which voltage dependent variation of dielectric constant is a maximum by autostabilized dielectric heating of bodies 21, 13. Impedance of the resonant circuit is modulated by signals from source 9 and the output across the circuit is demodulated at 100 and fed to an RC circuit as shown.

IPC: C01B3/12
Abstract: 1,053,788. Carbon monoxide conversion. HEINRICH KOPPERS G.m.b.H. May 5, 1965 [May 27, 1964], No. 18899/65. Heading C1A. [Also in Division C5] Gaseous mixtures containing carbon monoxide and sulphur compounds are treated for the removal or conversion of these compounds by a two-stage process. Firstly, the carbon monoxide is mostly converted to the dioxide by reacting the crude gas with water vapour, also producing hydrogen. Then, the partiallyconverted gas which may be subjected to heat exchange with the original crude gas, is desulphurized at high temperature, and then cooled with water producing water vapour for conversion of some more carbon monoxide to dioxide at low temperature, also giving more hydrogen. This low-temperature conversion acts simultaneously to the desulphurisation. A specific example of crude gas containing hydrogen is given in which the hydrogen content is substantially increased.

The station comprises N information channel gates 8 . . . 8N sequentially switched into their time slots by signals CTS 1  . . . CTSN from generator 18, for coding in coder 2 and transmission over line 15. For reception, the information time slots are decoded in decoder 3 and distributed by sequentially operated channel gates 13...13N. During the transmission, synchronizing and/or signalling time slots switches 9, 10 are changed over by the time slot signals SYTS, SITS, such that a test signal from generator 4 is fed to the coder 2 and after coding therein passes to store 7. During the reception synchronizing and/or signalling time slots switches 11,12,14 are changed over by the time slot signals SYTS, SITS such that the stored coded test signal passes to the decoder, is decoded therein, and passes to one input of a comparator 5, where it is compared with the direct test signal from generator 4. Any detected difference larger than a predetermined amount (indicating a faulty decoder and/or coder) causes a fault indication. The comparison circuit 5 may comprise a differential amplifier and the predetermined amount may be determined by a Schmitt trigger circuit 6 with an adjustable threshold. As the supervision is performed during the synchronizing and/or signalling time slots, there is no interference with the transmission of information.
