Title: Process for the production of diazo compounds
IPC: C09B41/00
Filed: 1976-04-20
Abstract: In the novel, automated process for diazotising aromatic amines, a previously selected, automatically measured amount of the amine is mixed with 0.5-0.999 equivalent of diazotisation agent and 0-5 equivalents of an acid. The remaining amount of diazotisation agent required for the complete diazotisation is added periodically in portions, these additions being monitored automatically by an analyser detecting the presence of nitrous acid. Cooling is not necessary, but the mixture can be warmed to accelerate the reaction. The process allows the reaction time to be shortened considerably. This means that diazonium compounds can be prepared which would already have decomposed under the previously known conditions before they could be processed.

A device for detecting leaks in the slugs in a gas-cooled nuclear reactor detects the variations in radio-activity of the cooling gas streams, means being provided for successively testing gas streams from each of the channels. The graphite block 1 in an air-cooled reactor is provided with channels 2 in which gas-tight casings 3 enclose uranium. Valves 7 in the concrete shield 4 have collecting elements 5 supplying coolant air samples by pipes 8 to external detector apparatus. Electrically actuated valves 9 controlled by a switch 11 successively allow the air samples to pass through a dust filter 18 to a chamber 13 containing a counter 12 sensitive to beta rays of the fission products and to gamma rays. The counter 12 has thick walls to reduce the sensitivity to A<SP>41</SP> normally present. A band 23 having active carbon to adsorb gaseous radioactive products moves so as to present a fresh filter portion for every channel tested. An air pump 16 provides circulation and discharge to stack 17. A device 14 amplifies the counter impulses and provides voltage feed to a recording apparatus 15. When the radio-activity of the coolant air is below a predetermined limit the switch 11 rotates at constant speed and the activity in each channel is measured successively. If the activity in a channel exceeds this limit a contact 19 causes the switch 11 to stop and operates an audible alarm 21 and a lamp 20 indicating the channel concerned. By means not described, air is then collected continuously from this channel and tested and the above apparatus is again started, to test the remaining channels.

A directive radio aerial comprises a wave energy launching or receiving means associated with a feeder and at one end of an axis along which are spaced at quarter wavelength intervals a succession of metallic parts of dimensions less than a wavelength and extending in at least two dimensions. As shown, the feeder is a coaxial cable shorted at the aerial end by a metal plate h and having dipole elements i and k attached to its outer and inner conductors a quarter wavelength from the shorted end. Each element carries at its end semi-circular plates (j and l) of #/4 diameter and, including this, projects #/4 from the cable. The dipole is backed by a horn f, the position of which is axially adjustable by screwing it along the outer conductor of the cable. The centre metal rod b of the direction modifying part of the aerial is soldered to the plate 4 and extends for several wavelengths. This rod carries a number of discs a<SP>1</SP>-a<SP>22</SP> spaced a quarter of a wavelength apart and dimensioned to effect wave propagation at the correct phase velocity. In place of discs cones of revolution having their axes along the axis o, z may be used, or eliptical, square or arcuate plates. Metallic meshwork may be used instead of sheet metal and three or four parallel rods spaced about #/4 apart may replace the centre rod b. For aerials disposed at the corners of a square with their axes perpendicular to the plane thereof may be used in correct phase relationship to increase the gain. The aerial is stated to have a much greater bandwidth than would be obtained with a corresponding Yagi aerial. It may be protected by a jacket of thin insulating material such as rubberized nylon and other forms of primary element can be used.
