Title: Improvements relating to copper-containing fungicides
Inventor: POMOT JEAN LOUISE EMILE
IPC: C07D251/32
Filed: 1960-05-27
Abstract: Cuprammonium cyanurate is produced by reacting an aqueous solution of cyanuric acid with a water-soluble cuprammonium salt in ammoniacal aqueous solution or an aqueous solution of cupric salt with an ammoniacal aqueous solution of cyanuric acid; the cyanuric acid may if desired be obtained by heating urea.  In a continuous method an aqueous solution of ammonia is continuously brought into contact with and removed from the cyanuric acid in lump form to produce a solution of cyanuric acid, solid particles of cyanuric acid in the solution being separated and recycled. The resulting clear liquid is mixed under turbulent conditions with an aqueous solution of the water-soluble cupric salt and the resulting suspension of cuprammonium cyanurate is treated to separate at least part of the liquid, and part at least of the separated liquid is recycled to the first operation.ALSO:A fungicidal composition contains as an active ingredient cuprammonium cyanurate preferably having a copper content of 16-18% by weight, together with a liquid diluent incorporating dispersing or wetting agents and an adhesive or a solid diluent, preferably the active ingredient being present in a proportion of 0.2-3%.  The invention also relates to a method of combatting parasitic fungi on plants by treating the plants in cuprammonium cyanurate together with a liquid diluent.

Abstract: 772,474. Electric correspondence control systems. STANDARD TELEPHONES & CABLES, Ltd. July 29, 1952, No. 19123/52. Class 40 (1). [Also in Group XL (a)] Apparatus for measuring leaks in a vacuum system comprises two ionization manometer gauges 1, 2 of the type described in Specification 771,799, [Group XL (a)], connected in series with a pump for drawing air through the gauges, the vacuum system being tested with butane so that any vacuum leak introduces butane into the air stream, which, by means of a trap, is made to affect one gauge only, thereby producing an unbalance in the anode currents of the two gauges, which may be measured. Each gauge comprises a central wire anode 3 surrounded by a cathode 4 consisting of a cylinder with transverse baffle plates, and is surrounded by an A.C. energized solenoid 13 to cause free electrons inside the tube to travel in spiral paths and produce maximum ionization by collision. The presence of butane in the air flow increases the ionization in test gauge 1, and the butane is removed by a cold trap 11 filled with liquid air, whereby the air flow and the ionization current in comparison gauge 2 is reduced. A voltage proportional to each anode current is developed across load resistors 6, 7 and is rectified and amplified, the voltage from gauge 2 being used to bias the voltage from gauge 1, so that initially no output is obtained from the amplifier 21 associated with gauge 1, but with a leak in the vacuum system the anode currents change in opposite directions and is shown on a peak voltmeter 26 measuring the output of amplifier 21. Specification 678,695, [Group XL (a)], also is referred to.

Filed: 1949-07-22
Abstract: 669,597. Fish meal. AKTIESELSKABET ATLAS. July 22, 1949, No. 19313/49. Class 49. In a process for the production of fish meal from whole fish and/or from waste from the production of filleted and preserved fish, the starting material is freed from fins, skin, blood, entrails and is separated into flesh and bone components by impact thereon of jets of water, steam or air after which the flesh components are dried to 10-30 per cent moisture and ground, the product preferably being further dried to 5 per cent moisture. In an example 1000 Kgs. of cod are washed in cold water, immersed for 15 sees. in boiling water before treating in a rotary perforated drum under a water spray to remove the fins, skin and blood. The entrails and gills are then removed and after washing in cold water the material is coagulated in boiling water for 15 mins. and then treated with a shower of water in a rotary perforated drum to separate the flesh and bones, the former being filtered off and dried in an ordinary drying plant to about 20 per cent, stored for about three, days in a silo and then ground in an edge-runner mill the product being further dried by infra-red irradiation to below 5 per cent moisture. Grinding is preferably effected when the material is moist by beating, rubbing, rasping or scraping or combinations thereof whereby the fibres that stick together are separated without being ground into a dust-like powder. The perforated drums may be replaced by shaking tables, boxes or channels.
