Title: Improvements in and relating to the surface quality inspecting and sorting of manufactured articles
IPC: G01N21/88
Filed: 1960-05-13
Abstract: 919,984. Sorting photo-electrically. ZKL VYZKUMNY USTAV PRO VALIVA LOZISKA. May 13, 1960 [May 15, 1959], No. 17064/60. Class 40 (3). A sorting device comprises two photo-cells, one of which views the object to be sorted and the other of which receives light direct from the lamp illuminating the object. The photocell outputs are passed to a differential D.C amplifier which operates a bi-stable device which in turn controls the sorting mechanism. In the embodiment illustrated, the test object, a ball-bearing ball K, is rotated so that its surface is viewed in light from a lamp G by a photo-cell Ff. A second cell Fk receives light direct from lamp G through an adjustable diaphragm C 2 . The cells' outputs feed the differential D.C. amplifier Z. The difference voltage passes to the grids of a double triode E 3  which controls the bi-stable device E 4  to operate the sorting mechanism. The device is so adjusted that a defective ball causes the difference voltage developed by amplifier Z to be negative. Variation in output of the lamp G does not cause a non-defective ball to be rejected since such variation produces a similar variation in the outputs of both photo-cells. Lamp G may be supplied with alternating current. Further inspection of the ball for other defects, e.g. in shape, may be made by apparatus similar to that described above but omitting the bi-stable circuit, the output of that apparatus being fed at point 3 to the device described. The result of each inspection then acts independently on the bi-stable circuit.

Title: A process for the manufacture of ammonium sulphate
IPC: C01C1/242
Filed: 1934-06-11
Abstract: <PICT:0434622/III/1> <PICT:0434622/III/2> Ammonium sulphate is obtained from a sulphur dioxide-containing sulphuric acid sludge by reducing the sulphur dioxide content of the sludge to 2 per cent by weight or less of its sulphuric acid content and thereafter reacting the resulting acid sludge with ammonia to produce ammonium sulphate in which step the remaining sulphur dioxide is substantially expelled.  The sulphur dioxide content of the sludge may be reduced by aeration or by maintaining a vacuum thereon.  Treatment by aeration may be effected in a degasefier 6, Fig. 1, provided with downwardly sloping annular baffles 7 and a series of rotating plates 4, the sludge being supplied by a pipe 1 and preheated air by means of a conduit 10.  Treatment by means of a vacuum may be effected in a degasefier 17, Fig. 2, provided with plates 19 and annular trays 20, the sludge being supplied from a preheater 15 and the vacuum being maintained by a pump 18.  Other degasefiers may be used, such as a tank or group of tanks connected in series, each being provided with an agitator and suitable nozzles for admitting the sludge and pipes for removing the gases and treated sludges. Preferably, the sludge should not be heated to a temperature exceeding 70 DEG  C. Temperature of 30 DEG  C. or 52 DEG  C. are given as examples.  The said sludge containing a reduced amount of SO2 may be reacted with ammonia in the presence of a large excess of approximately saturated ammonium sulphate solution, the solution preferably being maintained slightly acid.  A high reaction temperature will expel most of the remaining sulphur dioxide.  According to an example the treated sludge is reacted with aqueous ammonia, some sulphur dioxide and water vapour being removed in the reaction.  The ammonium sulphate solution is separated from accompanying oily material, say by mechanical separation or extraction, and is then fed to evaporating apparatus.  The remaining sulphur dioxide is removed from the solution during evaporation.
