Patent GB-489524-A (GB)
Abstract: 489,524. Rotary furnaces. METALLGES. AKT.-GES. May 13, 1937, No. 13558. Convention date, Nov. 6, 1936. [Class 51 (ii)] In a rotary furnace cooling-tubes are provided which extend across the furnace from one side to, or nearly to, the other, and which do not provide any communication with the interior of the furnace. The tubes may be fitted, e.g. near the exit end for the furnace gases to lower their temperature, or at the opposite end for cooling the charge, and the heat absorbed by the gaseous cooling medium may be usefully employed, e.g. in the case of an ore-roasting furnace, air may be heated for use in the reaction. In the construction shown the tube 23, which may be ribbed both externally and internally, is secured at one end to the furnace shell by gripping the flange 25 between the outlet connection 26 and a ring member 27 on the shell, while the other end is free to slide through a stuffing-box connection 29 associated with the inlet piece 31. The tubes may be connected in series and are supplied with cooling-medium from a header rotating with the furnace. In a modification, Fig. 3 (not shown), the cooling member is of Field tube form with inlet and outlet connections at the same end, and in a further construction, Fig. 4 (not shown), concentric tubes are used each with inlet and outlet connections arranged for separate counterflow supply of cooling- medium. Specification 422,163 is referred to.

Title: Process for the stabilisation of cyanhydrins
Filed: 1963-12-13
Abstract: An unsaturated aliphatic aldehyde cyanohydrin in solution in an organic unsaturated nitrile is stabilized by acidification of the solution by addition of a strong non-volatile organic acid which is soluble in the solution; suitable acids are oxalic, benzenesulphonic and toluenesulphonic acids, and are preferably used so as to bring the pH of the liquid phase to below about 4.4. A suitable starting solution for stabilizing is one of acrolein cyanohydrin in solution in acrylonitrile containing alkali, as produced by alkaline treatment of a product obtained during the production of acrylonitrile by the vapour phase reaction between propylene or acrolein and ammonia and oxygen at elevated temperature in the presence of an oxidation catalyst. Such a product stabilized as above can be distilled to obtain acrylonitrile free of acrolein.

The slots 4 and recesses 2 of the bricks may be back-cut e.g. dovetailed (Fig. 7 not shown) so that the bricks may be connected laterally by appropriately shaped members. Connecting members which fit into a plurality of slots may be provided. The basic components may be moulded in the form of plates. strips, T or corner members and the module unit may be shaped so that the bricks or assemblies thereof may be fixed at an angle to each other with transitional members provided to connect and strengthen components connected at such an angle. Roof and gable members based on the same module system and also capable of being cut to size can be provided, together with wheels having hubs attachable to the projections of the building components with hub caps for concealing the axle holes.

Abstract: 1,101,065. Document scanning apparatus. INTERNATIONAL BUSINESS MACHINES CORPORATION. 14 Nov., 1966 [26 Nov., 1965], No. 50856/66. Heading G4R. [Also in Division H4]  Document scanning apparatus comprises means for scanning a beam across a document, means for detecting when the beam crosses an edge of the document and means responsive to said detecting means for reversing the direction of scan. A " flying-spot " cathode-ray tube scanner performs a raster scan along a line of characters on a document for character recognition purposes. Then the scanning beam is returned quickly to the line beginning and the document advanced so the next line can be scanned. The direction of the beam is reversed at both edges of the document by detection of a black background on which the document is positioned, this black background being distinguished from the black of printed characters by the length of black regions in the scan, by means of a series of delays and inverters. The delays delay only positive-going edges of pulses applied to them. One delay, supplied with a positive level for black, produces no output for character black pulses since the delayed positive-going pulse beginning would occur after the negativegoing pulse end, but does produce an output for background black pulses since these are longer. Latches are controlled by this delay and each other to control the scan direction. Use of the invention in facsimile transmission is also mentioned.
