Title: Improvements in and relating to central heating systems
IPC: F24D3/02
Filed: 1919-06-04
Abstract: 156,829. Woude, D. van der. June 4, 1919. Heating by circulation of fluids.-Relates to central hot-water heating-installations of the kind in which the return pipe is used as a continuation of the supply-pipe with an interposed valve therebetween, the return pipe discharging into a tank open to the atmosphere disposed at or about the level of the heating-device, to which the water is returned from the tank by a pump. According to the invention, each radiator 4 in such a system operated at reduced or entirely free of pressure by providing the inlet pipes from the supply-pipe 3 with a valve 4 so as to restrict the volume of water admitted, while providing an unrestricted outlet discharging into the pipes 5 communicating with the return main 6. The control valves referred to are arranged in inlet pipes situated at the upper level of the radiator, and the discharge pipes 9 rise to the same height to enable the radiators to be filled. The outlet pipe 9 may be arranged as a siphon which is open to the atmosphere through the valve 9 when the radiators are in use, or a pipe 12<1> with a lower discharge pipe 12 provided with a valve may be used. To provide for a small consumption when a large number of radiators are cut off, the supply and return pipes 2, 6 are connected through a valve 10 which opens automatically more or less according to the pressure in the supply-pipe. At a time of small consumption prior to an expected increased use of hot water in the radiators, the supply-pipe 2 may be put into direct communication with the hot-water supply tank 11 through an auxiliary pipe provided with a valve. The boiler may then be fed with hot water from the tank when the system can take more than the normal quantity.

Patent GB-361297-A (GB)
Title: Improved process for the production of acetone
IPC: C07C45/00
Filed: 1930-05-12
Abstract: <PICT:0361297/IV/1> Acetone is obtained by subjecting the vapours containing ethyl alcohol and steam which are given off when distilling alcoholic mashes, preferably after first separating impurities of high boilingpoint, to elevated temperatures, generally between 250 and 600 DEG  C., in the presence of suitable catalysts such as oxygen compounds of heavy metals.  Any methyl alcohol present in the vapours, for example, when treating mashes obtained from sulphite waste liquors, is unchanged by the treatment, and the resulting mixtures containing acetone and methyl alcohol are useful as solvents.  Catalysts specified are the oxides of iron, nickel, manganese, and copper, and mixtures thereof.  Promoters, for example, calcium carbonate, magnesium oxide, barium oxide, or zinc oxide may also be present, and the catalysts are preferably used on carriers of good heat conductivity such as rusty iron sponge. The vapours are preferably circulated over the catalysts until the ethyl alcohol is completely converted to acetone.  According to an example, the mash passes through a pipe 1 into a column 2 provided with a deplegmator in which the volatile constituents of the mash are vaporized, the outflow containing only enough water to enable the solid impurities in the mash to be removed.  The vapours are led through a pipe 3 into a column 4 in which the alcohol concentration is increased and the fusel oils and other impurities of high boiling-point are condensed and withdrawn through pipes 5, any ethyl alcohol in the condensate being recovered, if desired, and returned to the columns 2, 4.  The vapours containing ethyl alcohol and steam, together with some acetaldehyde and ethyl acetate, pass by pipes 6, 7 to a furnace 8 in which the ethyl alcohol is catalytically converted to acetone. The product is led through a pipe 9 to a column 10 in which acetaldehyde and small quantities of acetone are separated, this condensate being returned to the furnace 8 through pipes 11, 7. The outflow from the column 10 passes through a pipe 12 into a column 13 in which the bulk of the acetone is separated, the condensate being returned through a pipe 14 to the column 4 for retreatment.
