Title: Process for the recovery of valuable constituents from yeast, etc.
IPC: C12N15/10
Filed: 1944-11-20
Abstract: Purine-nucleotides, other than those having a substituted 7-position in the purine group, are extracted from a nucleoprotein containing the same by heating such substance in the presence of an aqueous solution of caustic alkali until the nucleic acid is freed from its protein combination and hydrolysed into its nucleotide constituents which pass into solution, together with the gum and protein constituents of the substance and thereupon successively precipitating and removing the latter constituents from the resulting slurry and finally precipitating the purine nucleotides.  The gum and protein constituents may be precipitated in either order. Preferably, the slurry obtained by treatment of the nucleo-protein, say, yeast with alkali is treated with a mineral acid such as sulphuric acid to adjust its pH to substantially the isoelectric point of the proteins, whereupon the solution is boiled, cooled and the coagulated proteins removed together with insoluble yeast components such as cell walls; the solution is then treated with alkali until the isoelectric point for the precipitation of the gums is reached and the gums removed.  Alternatively, the gums are first precipitated from the initial strongly alkaline slurry by addition of copper sulphate and removed, and the solution then treated as above to remove the protein constituents.  The gum and protein-free solution containing the purine nucleotides is then treated for their precipitation; the method described in Specification 590,995 may be followed for precipitating them in the form of the cuprous salts which may be further treated as therein described. According to examples, yeast is hydrolysed with 2-3 per cent caustic soda at 60 DEG  to 65 DEG  C. for an hour, the gum and protein constituents successively precipitated and removed by either of the above methods and the resulting clear solution is adjusted to a pH value of between 5.5 and 8.5, heated to boiling and copper sulphate and sodium bisulphite added, preferably, to give a final pH of between 2.9 and 3.1 and the precipitated cuprous purine nucleotides are then filtered off and washed.  In addition to yeast, moulds, bacteria, blood cells and other nucleic acid bearing substances may be similarly treated.ALSO:A high protein feed adjunct is obtained by heating a nucleo protein, especially yeast, in the presence of an aqueous solution of a caustic alkali until the nucleic acid is freed from its protein combination and hydrolysed into its nucleotide constituents which pass into solution together with the gum and protein constituents of the nucleoprotein and then precipitating the proteins, suitably, by adjusting the pH of the hydrolysis mixture to the isoelectric point for the proteins.  Insoluble yeast constituents such as cell walls present in the hydrolysis mixture may be removed before the precipitation or together with the precipitated proteins.

Abstract: 441,987. Protective arrangements. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London. Aug. 16, 1935, No. 23093. Convention date, Aug. 17, 1934. [Class 38 (iv)] In a system comprising two circuits of different voltage interconnected through an auto transformer and one of which has an insulated neutral, protection against transient voltage differences between the circuits, which might result in a displacement of the neutral, is avoided by means of voltage responsive discharge means connected across the parts of the winding in series in the circuit and also between the neutral and earth. These limit any transient voltages occurring. In the form shown, the series windings 20 are bridged by spark gaps 21 in series with resistances 22 of the type in which the resistance decreases rapidly with increasing voltage, and the neutral N is connected to earth through a resistance 24 of the same type. Where the neutral of the generator 6 supplying one of the systems is earthed through a resistance, displacement of the neutral is prevented by means of a delta winding on the transformer 10. If desired a unity ratio autotransformer may be used to interconnect the lines with booster transformers in series in the line fed from winding thereon. In this case the discharge means are in parallel with the booster windings in series in the line. Specification 292,110, [Class 38 (iv)], is referred to.

Filed: 1972-05-17
Abstract: 1386476 Automatic exchange systems M REVEL 17 May 1972 [18 May 1971] 23155/72 Heading H4K In a system in which trunks are arranged in groups in accordance with their specific destinations, a trunk hunter in hunting for a free trunk in a particular direction tests the trunks in a quasi-random manner such that two successively tested trunks do not belong to the same group. The system is used for trunk hunting among analogue - signal - carrying trunks extending between two TDM switching networks which may be handling PCM traffic. In operation, a central control inserts the addresses of the first and last trunks in the group pertaining to a wanted direction into two address registers and then starts a circulating memory containing the addresses of all the trunks handled by the hunter. The first address appearing at the output of the memory is stored as a reference and then each following address is compared with the contents of the address registers in order to determine whether it belongs to the group defined by the contents of these registers. Such permissible addresses are generally interspaced evenly among the circulating addresses but there is no definite requirement for this whatsoever. Whenever a permissible address occurs it is gated through to a translator that permits the corresponding trunk to be interrogated for its free/busy condition. If it is free, scanning stops and the various registers are cleared. If it is busy, scanning continues until a reference address has occurred twice which indicates that all the trunks have been scanned and that the scan was therefore unsuccessful. It is not suggested that further scans can be made in this case.
