Various embodiments formed by folding a shaped metal sheet are shown and described. Cantilever or the normal four legs may be attached to the seat.
Patent GB-369616-A (GB)
Title: Improvements in or relating to colour photography
IPC: G03C7/26
Filed: 1930-09-23
Abstract: 369,616. Colour photography. GASPAR, B., 1, Eminescu, Temesvar, Roumania. Sept. 23, 1930, No. 28428. Convention date, Sept. 24, 1929. [Class 98 (ii).] In a process of colour photography, two or more layers of emulsion, sensitized to different colours are superposed on a support, exposed and developed and the images converted into a mordant and dyed with a single dye. The surface layer is then decoloured and recoloured with a different colour. This may be effected by redyeing the layer or by treating the product of decolouring with a reagent generating a different colour, e.g. fuchsine may be decoloured with nitrous acid and coupled with resorcin giving a yellow colour. The recolouration may also be carried out by acting on the mordant with a colour forming agent. For example, the silver image is converted into lead ferrocyanide and dyed with rhodamine S. The surface layer is then decoloured and the mordant converted into lead chromate. The whole is then transferred to a fresh carrier with the former underneath layer on top and this layer is decoloured and the mordant converted into Prussian Blue by means of a ferric salt. To enable the reactions to be controlled, the outside layers are made thin relatively to the inner layer, control marks produced by exposure to areas of the primary colours are produced on the edge of the film and stop baths are employed to cause the cessation of the action when it has extended to the desired depth. For example, if a dye is decoloured with a reducing agent, the action may be stopped by immersion in an oxidizing bath. Other methods of colouring the decoloured surface layer, e.g. by toning the silver image present or by using for decolouring agents producing a differential hardening and dyeing the unhardened parts of layer, may be used.

Title: Processes of and apparatus for burning sulphur
Inventor: COATES WILLIAM HENRY
IPC: C01B17/54
Filed: 1964-07-10
Abstract: Sulphur dioxide is produced by burning S whereby molten is delivered to the bottom of a chamber in which a combustion zone is formed and is thrown upwards as a spray of droplets into the combustion zone by a carrier gas released upwards through the bottom of the chamber, combustion air being introduced into the combustion zone with a downward component of velocity at a point above the point of release of the carrier gas.  The carrier gas may be air, SO2 or N2.  Inside the burner 1, <PICT:1030917/C1/1> formed from refractory material, are a primary combustion chamber 4 and secondary combustion chamber 5 linked by converging ducts 6. Molten S is supplied through the U-tube 7 to the bottom of 4. Combustion air, preferably preheated, is fed to 4 through 12 and downwardly inclined passages 12a and to 5 through 13 and upwardly inclined passages 13a.  The carrier gas is supplied through pipe 14, which terminates below the bottom of 4, inside sulphur supply tube 7.
