Title: Substance Having Growth Promoting and Metabolism Promoting Action and Process for Recovering It
Inventor: HELMBOLD WOLFGANG
IPC: A61K35/14
Filed: 1967-04-20
Abstract: 1,188,656. Anabolic substance from haemolysed blood W. HELMBOLD. 20 April, 1967 [20 April, 1966], No. 18146/67. Heading A5B. [Also in Division C1]  A substance having growth promoting and anabolic activity is prepared by fractionating a haemolysate of the blood cells from the blood of young animals, by one or more of: ion exchange, absorption chromatography preparative high voltage electrophoresis, high voltage electrodialysis, gel filtration, preparative thin-layer chromatography and counter current distribution, and isolating the substance from the fraction having an ultra-violet absorption maximum at 245-246mu. The starting material is preferably spray-dried haemolysed blood, and the fractionation is preferably preceded by ultra filtration, e.g. through a high pressure membrane filter permeable to molecules up to mol. wt. of 10,000, to filter out high molecular weight impurities. Suitable chromatographic agents are dextran or cellulose based anion exchangers, or anion exchange synthetic resins or hydroxy-apatite. Counter current distribution may be effected in propanol or butanol, and thin layer chromatography is performed on silica gel with a butanol/acetic acid/water system. The substance is a water soluble anionic compound having a molecular weight of less than 700, and is not a peptide, sugar, lipid, nucleoside or nucleotide. It has the same electrophoretic mobility as serum albumin at pH 8.6; an Rf-value of 0.93-0.96 in butanol/acetic acid/water 0:1:1 on silica gel; and the following U.V. absorption maxima: 245-246 mÁ at neutral pH; 250-260 mn (255.5 mÁ at pH 2.0; and 280-281mÁ at pH 12.0. Compositions comprising the substance together with a carrier are used for pharmaceutical application or for stimulating the growth of crops (see Division C1). Pharmaceutical compositions suitably contain the active substance in such a concentration that, after 20 fold dilution with water, they have an extinction coefficient of at least 0.6 at 246 mÁ.

Abstract: 958,960. Pulse radar. MARCONI'S WIRELESS TELEGRAPH CO. Ltd. March 27, 1958 [June 7, 1957], No. 18179/57. Heading H4D. An M.T.I. system which although utilizing micro-wave transmitted frequencies, avoids the defect of " blind speeds " which are close together, and which so far as this defect is concerned presents the characteristics of a radar system having a low radiated frequency, comprises oscillators 1, 2 generating, respectively, a frequency F 1  in the micro-wave band and a frequency f 1  in the metre band, these outputs being fed to a mixer 3 to obtain a frequency F 1 +f 1 =F 2 . The frequencies F 1 , F 2  are fed to gating stages 4, 5 controlled by a pulse generator 6, a delay unit 7 ensuring that the pulses from 5 are delayed in time by an amount equal at least to the length of the pulses produced by 6. Thus pulses of adjacent frequencies F 1 , F 2  are fed alternately to a transmitting receiving aerial A, the echo pulses F 1 +d 1 , F 2 +d 2 , where d 1 , d 2  are the corresponding Doppler shifts, being separated by a filter 11 and fed, respectively, to mixers 13, 12 connected to a local oscillator generating a frequency F 3 . The output from 13 is fed through an amplifier 17 and delay unit 18 giving a delay equal to that of unit 7, to a phase detector 19. The output from 12 is fed to a mixer 15 connected to the oscillator 2 and through an amplifier 16 to the detector 19. Thus pulses of frequencies F 1 -F 3 +d 1  and F 1 -F 3 +d 2  arrive simultaneously at the detector 19, the output d 1 -d 2  of which is fed to a modulator 20 controlling a 10 mc/sec. carrier source 21. The output from 20 takes one path through a detector 22 and another path through a delay line 23 where it is delayed by an amount equal to the reciprocal of the pulse repetition frequency, the outputs from the detectors 22, 24 being combined at 25 in amplitude opposition, the output from 25 being fed to a P.P.I. display tube 28. In a modification (Fig. 2, not shown), the frequencies F 1 , F 2  are generated directly by magnetrons which are switched, alternately, by a pair of modulators triggered by a pulse generator. Specification 778,147 is referred to.

Title: Manufacture of new azo-dyestuffs insoluble in water on the fibre
IPC: D06P1/12
Filed: 1931-06-24
Abstract: Azo dyes are made on the fibre by coupling a monodiazonium salt of an anthraquinone derivative, which as non-diazotized aminocompound has a blue colour and on diazotization does not undergo any alteration in its structure, apart from the conversion of the amino group into the diazonium group, with an acetoacetic acid arylide, an arylamide of a carboxyphenylmethylpyrazolone, or a urea obtained from a pyrazolone, the components being free from substituents which would render the products soluble in water or alkalies.  Green shades are obtained on cotton and artificial silk, e.g. viscose.  In examples the following dyes are produced on the fibre according to customary methods: (1) . . (4) 1-amino-4-cyclohexylaminoanthraquinone --> diacetoacetyl-o-tolidine; the 4-n-butyl, n-propyl- and methylamino derivatives are also specified as diazo components, (5), (6) 1-amino 4-phenylaminoanthraquinone or 1 - amino-4 : 4<1> - N - methylacetylaminophenylaminoanthraquinone --> 2-(4-acetoacetylamino) - phenylbenzimidazole, (7) 1-amino-4-phenylaminoanthraquinone --> diacetoacetyl-o-tolidine, (8,) (9), (10) 1 : 4 : 5 : 8-tetraminoanthraquinone --> diacetoacetyl-o-tolidine (copper chloride and chromic acid may be added to the diazo solution or the dyeing may be after-treated with these compounds), or the pyrazolone prepared from acetoacetic ethyl ester and the hydrazine from m-aminobenzoic acid-5-chloro-2-toluidide, or the urea from 1-p-aminophenyl-3-methyl-5-pyrazolone, (11), (12) bleached cotton material is padded with diacetoacetyl-o-tolidine or diacetoacetyl-p-phenylenediamine and printed with a paste containing diazotized 1 : 4 : 5 : 8-tetraaminoanthraquinone.

Title: Improvements in sawtooth current generators
Inventor: GIFKINS GEOFFREY CHARLES
IPC: H03K4/34
Filed: 1956-06-14
Abstract: 869,925. Saw-tooth generating circuits. MURPHY RADIO Ltd. Sept. 16, 1957 [June 14, 1956], No. 18482/56. Class 40(6) The efficiency of a self oscillating sawtooth current generator is improved by generating from the anode circuit transformer a diminishing negative voltage which is fed to a second electroncontrolling grid to cut off the valve during part of the cycle when the economy diode circuit is operating. As described, the circuit is made to oscillate by inductive coupling between anode and screen. Fig. 1 shows an embodiment in which the negative pulse at the screen during the flyback is integrated by resistor 9 and capacitor 11 before being applied to the grid, the voltage on capacitor 11 holding the valve cut off during the first part of each sweep while the economy diode 4 is conducting. Negative synchronizing pulses are fed in via capacitor 13. The frequency is adjusted by variation of the screen circuit resistance, part of which (7) is fixed. The variable resistor 8 thus forms a hold control. In Fig. 2, the negative voltage across the hold control 8 is smoothed by resistor 14 and capacitor 15 before being applied to the grid via a diode 16 so that both the grid and screen are used in frequency adjustment. Negative pulses are fed via diode 16 so that coupling between flyback and the synchronizing circuit due to screen-to-grid capacitance is less likely to disturb interlacing. In Fig. 3 the grid is driven diminishingly negative by feeding back a positive flyback pulse from a further winding 17 so that capacitor 18 becomes negatively charged by grid current. The time constant of capacitor 18 and resistor 21 is made about 1/5th of the sweep period so that the valve begins to conduct after about <SP>1</SP>/ 3 rd of the sweep. Resistor 21 may be decoupled from resistor 8 to avoid the change of voltage across the hold control 8 affecting the grid voltage. The capacitor 18 should be made much larger than the screen-to-grid capacitance. Specifications 643,993, 700,453 and 700,454 are referred to.
