Abstract: 1530477 Acid absorption of ammonia MONTEDISON SpA 24 Nov 1975 [29 Nov 1974] 48187/75 Heading C1A The absorption of ammonia by a circulated stream of an aqueous acid slurry or solution is effected in an absorption zone where the pressure is sufficient to prevent generation of water vapour and the resulting hot solution or slurry is then fed to a separation zone of lower pressure to release the water vapour, fresh acid being fed to the circulated stream and some of the stream being withdrawn as product. The pressure difference between the zones may be partially generated by a difference in height and/or a flow resistance between the zones. The absorption zone may be located in piping to which the acid and ammonia are fed under pressure and the solution from the separation zone may be recirculated through the absorption zone to which fresh acid solution or slurry is fed. The separation zone may be a flash chamber. The acid may be aqueous, phosphoric, sulphuric, or nitric acid or a solution or slurry derived from nitric or sulphonitiric acid attack on phosphate ores.

Abstract: The invention comprises pelletized particulate material which is self-bonded and has a principal phase consisting of synthetic mordenite.  The pellets may be formed from a powdered aqueous mixture having a molar composition of Na2O. 1 to 1.33 Al2O3.  8.5 to 11 SiO2 excluding water fired at a temperature high enough to produce self-bonding but not complete vitrification, e.g. 600 DEG  C. for 1 hour, and heated at a reduced temperature with an aqueous solution of sodium silicate or caustic soda or a mixture thereof. The initial mixture may be prepared from kaolin, diatomaceous earth, sodium silicate, and water. A typical composition comprises 19.15% kaolin, 26.57% diatomaceous earth, 54.28% aqueous sodium silicate, and 7.7% water.

Abstract: 1286827 Television SONY CORP 6 Oct 1969 [7 Oct 1968] 49072/69 Heading H4F In an arrangement for feeding colour signals, rather than colour difference signals, to the electrodes of a colour picture tube, a luminance signal at 17 is fed via a low-pass filter 18 to an input of a demodulator 1, chrominance (colour difference) signals and reference subcarrier signals being supplied at 6<SP>1</SP> and 2<SP>1</SP> respectively, and the low bandwidth colour signal is amplified and fed to the base of a transistor 14R, the emitter of which is supplied with the luminance signal via a high-pass filter 19. The output of the collector therefore comprises colour information with higher frequency luminance information superimposed, and avoids the need to use wideband colour video amplifiers, e.g. for transistor 10. Simultaneously, since the highfrequency luminance signals are only of low amplitude, the high frequency transistors 22 do not need to be of high power rating. In a modification, Fig. 2 (not shown), the high frequency luminance signal is fed to each RC network 29, 30 by an individual transistor 22.

Load rope 27 is separated from its hook 31, passed over a pulley 32 at the top of the tower 9 and secured to the bottom jib 1 through rope extension 34 and connection 33. Joint 8 can then be released and the rod 7 lowered on to the bottom jib 1 by a hand winch (not shown). Joint 15 is then released when, by operating the hoisting mechanism, the jib system 1, 4, 7 can be lowered, Fig. 3 (not shown). The tower 9 may now be lowered by bringing the frame 17 into the upper position using the luffing mechanism, releasing the joint 12 and lowering the tower 9 on to the luffing frame 17.
