Title: The treatment of distillery wastes
Inventor: WEBB WILLIAM HARRY ARLETT
IPC: A23K10/38
Filed: 1956-04-11
Abstract: <PICT:0869059/III/1> Solids, which may be used as an animal feeding stuff, are recovered from distillery effluents discharged from a distillation process which involves mashing and distillation stages by a process in which the effluents are concentrated to high solids content by evaporation in a multiple effect evaporator, the first effect of which is heated by using normal process steam and subsequent effects by at least part of the steam generated in preceding effects, the concentrated effluent being dried, and steam generated during the evaporation not utilised in the distillation being used in the mashing stages.  Final concentration of the effluent immediately prior to drying may be effected under reduced pressure and the final drying is effected by a vacuum drying treatment or on a roller drum drier.  Solids in suspension may be filtered off from the effluent and either treated separately or incorporated with the evaporated solution. The effluents may be spent wash, steep water, spent lees or pot ale.  In a typical Example (3) applied to the operation of a distillery manufacturing alcohol from grain, fermented wash is fed through line 2 to an analysing column 1 where alcohol is stripped.  Spent wash passes through line 3 and to evaporator 4 which is heated by live steam and then successively through evaporators 5 and 6 which are heated by vapour generated in the preceding effects.  The final concentrate leaving stage 6 is fed to a dryer 9.  Vapour generated in evaporator 5 is divided into 2 streams one is used to heat evaporator 6 and the other to heat water in surface condenser 7.  A small extra supply of steam is obtained by flashing condensate in tanks 13 and 14.  Vapour liquid separators 10, 11 and 12 remove entrained liquid.

Title: Improvements in or relating to aerial systems and feeding systems therefor
IPC: H01Q21/12
Filed: 1926-04-30
Abstract: 274,970. Green, E. April 30, 1926. Directive signalling ; coupling oscilllating and radiating circuits.-Relates to extended aerial systems, such as are used in directive signalling, and consists in means for minimizing the creation of stationary waves along the feeder cables by which the aerial network is energized from the power house. In the system shown the coupling to each of the aerials A' - - A<4> is so adjusted that the effective load on each of the feeder sections 1, 2 and 3, 4 is equal to the surge impedance Ro, so that there is no reflection along these sections. The effective load on the intermediate cables 5, 6 will then be ¢ Ro at each of the junction points T1, T2, and reflection will occur. In order to eliminate the effect of this upon the final section 7, each of the sections 5. 6 is made an odd number of quarter wave-lengths long, whereby the effective impedance of each section at the junction T3 is 2Ro and the resultant load of the two sections in parallel upon the section 7 becomes Ro.

Abstract: The invention comprises compounds of the formula <FORM:0887958/IV (b)/1> where R is one or more substituents selected from CH3, CH2CH3, CH(CH3)2, C(CH3)3, C6H5, CF3, CN, COCH3, CO2C2H5, CO2H, NH2, NHCH3, N(CH3)2, N(CH3)3+, NHCOCH3, NO2, PO3H-, OCH3, OC2H5, OCH2CH2CH3, OC6H5, OH, OCOCH3, SCH3, SH, SCOCH3, SCN, SOCH3 (methyl sulphinyl), SO2CH3 (methyl sulphonyl), SO2NH2, S(CH3)2+, F, Cl, Br, I, IO2, CH2CH=CH2 and CO2CH3; these substituents are to be sterically compatible as defined below, and are to satisfy the expression 3.10992\sE3.41S #s(R.q)\sE5.19343 51\sEq\sE81 where R is the substituent in the q-position; these sigma values are given.  These compounds are colourless in solution, but on irradiation with blue to ultra-violet light the 21-11 bond is broken and the compounds are coloured; irradiation with electro magnetic radiation of wavelength predominantly longer than blue reverses the process.  "Sterically compatible" substituents are those which do not hinder the breaking of the 21-11 bond on irradiation.  The compounds in solution can be used to sensitize record materials for the recording and erasing of data by the appropriate radiation.  The 61-chloro-81-nitro-and 61-bromo-81-nitro-derivatives are disclaimed.  In an example the 51,71-dichloro-61-nitro-derivative is obtained by reacting 3,5-dichlorophenol with chloroform in an aqueous alkaline solution to prepare 4,6-dichlorosalicylaldehyde, nitrating the latter to obtain 4,6-dichloro-5-nitrosalicylaldehyde, and condensing this with 2-methylene-1,3,3-trimethylindoline in the presence of ethanol. The other compounds of the invention may be obtained by condensing 2-methylene-1,3,3-trimethylindoline with a suitably substituted salicylaldehyde.  Specification 872,005 is referred to.
