Title: Flavanone derivative and a method for its preparation
IPC: A61K36/484
Filed: 1973-11-28
Abstract: 1439398 Flavanone derivative H TROM. MSDORFF 28 Nov 1973 [8 Dec 1972] 55278/73 Heading C2C A novel flavanone derivative obtainable from succus liquiritrae, having the empirical formula the presumed structural formula (in which the 3-position side change is that of a dimeric methylated hexuronic acid) exhibiting an Rf value of 0.79 in a thin-layer chromatogram on silica gel in a 2 : 1.5 water (saturated with chloroform)-glacial acetic acid system, is obtained from an aqueous dispersion prepared from a mixture extracted from roots of glycyrrhiza glabra by treating with a solvent thereby dissolving the undesired red dyestuff, adjusting the pH of the reaction mixture to a moderately acidic value by addition of water or dilute acid thus precipitating a glycyrrhizinic acid contaminated with yellow dyestuff, separating and discarding the supernatant solution containing the red dyestuff, dissolving the precipitate in dilute alcoholic acid and subjecting to an alcoholysis with simultaneous methylation, discarding the precipitated glycyrrhetinic acid and obtaining the flavanone by boiling down and drying the remaining solution. The starting material may be an extract from succus liquiritrae. Alternatively, instead of the aqueous dispersion, there may be used as starting material a commercial dyestuff-containing ammoniacal glycyrrhizine dissolved in concentrated nitric acid. The solvent used to dissolve the red dyestuff is preferably ethyl urethane. Pharmaceutical compositions, suitable for treating various diseases of the gastric and intestinal tract, wound cicatrization and for treatment of inflammation, comprise a flavanone as described above, together with one or more conventional solid or liquid adjuvants or carriers, in forms suitable for administration orally, topically or intramuscularly.

Title: A method of treating spodumene
IPC: C04B33/24
Filed: 1966-12-16
Abstract: Lattice bound iron is removed from spodumene in a process that comprises treating finely divided a - or b -spodumene with chlorine gas at a temperature of from 954 DEG  to 1204 DEG  C. to reduce the lattice bound iron content to less than 0.3% calculated as Fe2O3.  A substantial proportion of free magnetic iron compounds in the spodumene (amphibole, triphyllite and chloride) may be removed by magnetic separation prior to treatment with chlorine.  Quantities of free iron compounds or minerals may be removed by a vibratory treatment after chlorination, and further magnetic tretment may be performed.  If the spodumene starting material is in the a -form, then the temperature should be above 982 DEG  C. to convert the a -form into the b -form since the iron in the b -form is directly attacked by the chlorine.  The chlorine may be present as up to 5%, preferably 10-50% by volume of a chlorinating mixture of air and chlorine, and the iron chloride may be separated from the gaseous products by condensation.

There may be four stages viz. a lag phase (5 hours), first half of the log phase (5 hours), latter half of log phase (3 hours) and a decrement and stational phase (8 hours) with aeration supplied in the proportional amounts 0À2 : 0À3 : 1À0 : 3À0 by volume. The method may be used in the cultivation of Candida sp. in an aqueous medium containing particles of C 7 -C 20  nparaffins.

As shown, the bales 6 travel up a conveyer 7 and drop into a position 6a on to a roller conveyer 8 which moves the bale forward one position 6b, the conveyer 7 then being restarted to bring another bale to position 6a. The conveyer 8 which comprises a pneumatically-operated transfer beam 40, Fig. 9, for moving the bales along rollers 33, is again actuated to move the first bale on to a bale guide 5 and to move the bale at position 6a to position 6b and to again actuate conveyer 7 to deliver another bale to position 6a. The pusher 9, Fig. 3, which is provided with a raised perimeter 10 and is hydraulically or pneumatically operated is then actuated to move the first bale on the guide 5 partially into the carton and to withdraw the guide to receive the next bale which is then pushed into the carton with the first bale before it. Upon entry of the last bale, the series of bales is driven by the pusher into contact with the base of the carton, after which the guide is withdrawn and the pusher 9 retracts. A scissors jack arrangement 4 is then actuated to lower the carton to position a second compartment in alignment with the guide. After all compartments have been filled, a pneumatically operated tipper mechanism 3 is actuated to move the filled carton to a vertical position for sealing and removal. The device is operated automatically by means of photo-electric cells, limit switches and timers and may be fully automated by inclusion of automatic infeed and discharge conveyers for empty and filled cartons, respectively.

Abstract: 1,242,339. Transistor switching and oscillator circuits. INTERNATIONAL STANDARD ELECTRIC CORP. 10 Dec., 1969 [13 Dec., 1968], No. 60329/69. Heading H3T. A solid state bi-directional switching circuit is actuated by a D.C. input signal which is converted into an R.F. signal (e.g. 40 to 100 mHz.) and coupled to a detector isolated from the input as far as D.C. is concerned, the detector operating the switching means. The D.C. input at 1, 2 constitutes the power supply for an oscillator comprising transistors 12, 13, 14; two further transistors 15, 16 are amplifiers to which opposite phase output terminals A, B are connected. A and B are coupled to the detector 8 via capacitors 4 ... 7 which provide the D.C. isolation. As shown, the detector comprises diodes 22, 25 which conduct on alternate half cycles and turn on transistors 23, 26. These remain on during the non-conductive half cycles of their associated diodes due to the time required to dissipate the charge on their collectors. Thus, both transistors 23, 26 are conductive all the time that the oscillator is on. An alternative detector (Fig. 3, not shown) has transistors in place of the diodes; when these conduct they turn on their associated main transistors and during the opposite half cycles the main transistors are turned on directly. Conduction of transistors 23, 26 turns on transistors 28, 29 in the switching stage 9, which are connected in opposite directions to allow bidirectional signals to pass between terminals 10, 11. The complete circuit may be made in integrated form, and is applicable to telephone circuits.
