Title: Improved heat cycle for power plant
IPC: F01K7/40
Filed: 1961-03-07
Abstract: 964,013. Power plant. A. FURREBOE. March 7, 1961, No. 8216/61. Heading F1Q. A power plant comprises a boiler 10, Fig. 1, a turbine 40 and a condenser 26 connected in series by a conduit 39, heat exchangers 13, 24 disposed in a feed water return conduit 42, a refrigeration generator 11 connected by conduit 12 in series with the heat exchangers and condenser, whereby the refrigerant flowing from the generator causes successive heating of the feed water and cooling of the condenser. Heated refrigerant from the refrigerant boiler 11 situated in the fire box or flue of steam boiler 10 is cooled and condensed in the feed water heaters 13, 17, 24 and passes into coils 29 and 29A where it cools respectively water from the primary cooler 33 and steam in the main condenser 26. The gaseous refrigerant then passes through pipes 30, 31 to absorber 17A where it mixes with and is absorbed by weak hot refrigerant liquor from the generator 11 passing through pipe 31A to form strong refrigerant liquor which is cooled by water in coil 17B and pumped by pump 32 back to the refrigerant boiler 11 to recycle. Heat given up in the chemical reaction of the absorbtion process is also taken up by water in coil 17B. Cooling water is circulated from primary cooler 33 through pipe 34, pump 35, pipe 36 to sub-cooling circulating water tank 29B, through pipe 37 to main condenser 26 and returns through pipe 38 or through valve 35A, pipe 35B to coil 17B in absorber 17A, and through pipe 17C, coil 17D, pipe 18 and pump 19 to boiler 10. Steam from boiler 10 passes through pipe 39 to turbine 40 and condenser 26 and steam condensate is pumped by pump 41 through feed water heater 24, pipe 42, heater 13, and pump 19 to boiler 10. In a modification cooling water for coil 17B is supplied from the steam cycle condensate in pipe 42. In further modification the refrigerant boiler 11 may be heated independently. In another embodiment cooling water is led through spray ring 26D, Fig. 2, into direct contact with bleed steam from turbine 40 and the mixed condensate passes through coil 17E in absorber 17A which acts as a feed water heater. The refrigerant boiler 11 is heated either by means of bleed steam through pipe 43 from turbine 40 or by steam direct from boiler 10 through pipe 39A to coils 43A and 39B. In a further embodiment the cooling refrigerant and steam condensate are passed through coils arranged within the partially-evacuated housing of an electrical generator driven by the turbine. The generator housing may be evacuated by connecting it to the main condenser.

Title: Organo-siloxanes and methods of preparing them
IPC: C08G77/06
Filed: 1946-03-18
Abstract: At least two monosilanes each containing one different hydrocarbon radical attached to silicon through C to Si linkages, the remainder of the silicon valencies being satisfied by hydrolysable radicals are hydrolysed and inter-condensed. Suitable hydrolysable radicals are hydrogen, halogens, alkoxy, aroxy and acyloxy.  A list of suitable hydrocarbon radicals is given in the Specification.  Halogenated hydrocarbon radicals may also be used.  The mixture to be hydrolysed may be dropped into the theoretical quantity of water, preferably dissolved in a common solvent, e.g. alcohol, ether, dioxane, acetic acid or acetone.  Acid catalysts may be present.  Hydrolysis may be partial, a water-miscible solvent, absence of acid catalysts, and low temperature aiding this condition.  In the examples: (1) dodecylsilicon trichloride and phenylsilicon trichloride dissolved in ethyl alcohol and "Cellosolve" (Registered Trade Mark) were hydrolysed and condensed by dropwise addition of water, removal of solvents and heating; (2) ethyl alcohol was added to mixed dodecylsilicon trichloride and phenylsilicon trichloride.  After evolution of HCl had ceased, water was added dropwise and the product then heated; (3) dodecylsilicon trichloride and methyltriethoxysilane were dissolved in Cellosolve.  Ethyl alcohol and water were added and the resin freed from solvents; (4) and (5) methyltriethoxysilane and phenylsilicon trichloride were heated in ethyl alcohol till evolution of HCl ceased.  Water and Cellosolve were added, the mixture heated and solvents evaporated; (6) aqueous ethyl alcohol was added to a mixture of phenylethyl silicon trichloride and methyltriethoxysilane. Excess was then added and solvents evaporated; (7) a solution of benzyl silicon trichloride and dodecylsilicon trichloride in dioxane was hydrolysed and intercondensed by slow addition of aqueous dioxane; (8) is similar to (7) using phenylsilicontrichloride and dodecylsilicontrichloride; (9) a solution of benzylsilicontrichloride and methallylsilicontrichloride in dioxane was hydrolysed and intercondensed by slow addition of aqueous dioxane; (10) methyl tri-ethoxysilane and dodecylsilicontrichloride were hydrolysed and intercondensed in aqueous ethyl alcohol; (11) benzylsilicon trichloride and phenylethylsilicon trichloride were hydrolysed and intercondensed in aqueous dioxane.  The products may be used as moulding compounds, film-forming coatings, varnishes, impregnating agents or embedding media for condenser plates.

Patent GB-773421-A (GB)
Title: Liquid-granular solids contacting
IPC: B01J47/10
Filed: 1955-03-24
Abstract: <PICT:0773421/III/1> <PICT:0773421/III/2> The continuous treatment of water with granular zeolites and the liquid phase conversion of hydrocarbons in the presence of either inert or catalytic granular materials are two of the processes to which the invention shown may be applied, and it is described in connection with the decolorizing of oil with e.g. fuller's earth. Hydrocarbon oil, optionally pre-heated, is introduced at 14 to a treating vessel 12, Fig. 1, and withdrawn at 15 while regenerated fuller's earth is introduced at 10 and withdrawn, contaminated, at 18.  The adsorbent is present in the regions 17, 18 and 19 as a continuous phase, thus acting as a seal against excessive liquid flow.  It is transported up a pipe 20 by some of the charge liquid introduced at 21, and is discharged therefrom along that one of a number of pipes 22 which is open, or along the lowest if more than one is open.  The choice of pipe 22 determines the difference in height between the liquid level 16 in the treating zone 12 and the height to which the suspension rises in the transport pipe 20 and thus determines the rate of withdrawal of adsorbent from the zone 12.  The adsorbent is cooled by wash solvent introduced at 24a and washed in a vessel 25 by further solvent introduced at 27 and withdrawn at 28 to a fractionater 29.  The adsorbent is withdrawn from the washer 25 in the same manner as from the treating zone 12 and passes to a fluidized-bed drier 40 to which steam is supplied at 41.  Heat-transfer coils may be incorporated. Solvent-steam mixture is withdrawn at 44 and condensed at 45, solvent returning to a tank 26.  Dried adsorbent passes at 47 to a regenerator such as a kiln.  From the fractionater 29 condensed solvent is returned to the tank 26 while oil is recycled at 33.  In the washer 25 of Fig. 2 no transport liquid is introduced at the bottom of the seal column 34, as it is in Fig. 1; instead, the column 34 is made wide enough to permit liquid from it to pass with the adsorbent up transport pipe 36. The solvent-adsorbent mixture eventually falls on to a rotating screen 49 whence adsorbent is scraped at 53 while solvent is removed at 51.  The rate of solids withdrawal is adjusted to maintain a constant bed level: the bed level may be ascertained by a device shown in Fig. 2.  The solids entering at 24 pass through a funnelshaped member 58 into a receptacle 60 supported by a rod 62 co-operating with a scale 63. The upper end of the columnar mass is situated within the receptacle 60; the weight of the receptacle 60 and the solids therein is constantly recorded by scale 63 and is a measure of the height of the solids. Specification 711,487 is referred to.
