Title: Method of recovering urokinase from urine
Inventor: KJELDGAARD NIELS OLE
IPC: C12N9/72
Filed: 1955-07-01
Abstract: A method of recovering urokinase, also known as the plasminogen activator in urine or the fibrinolytic activator in urine, from human urine comprises contacting an impure solution of urokinase, obtained by eluting an adsorbate derived from passing urine through an adsorbent with a synthetic cation-exchange resin, e.g. "Amberlite (Registered Trade Mark) IRC 50 XE-97," and eluting said resin with an aqueous solution of an electrolyte having a pH that will cause the eluate to have a pH between 5 and 11.  The first adsorption process using human urine is conveniently carried out by adjusting the pH of the urine to between 3 and 8, e.g. with sodium hydroxide solution, and contacting this with silica gel or a cation-exchanging silicate, e.g. the water-containing sodium aluminium silicates, then eluting with an aqueous solution, e.g. of ammonia, having a pH such that the eluate has a pH of between 9 and 11.5.  This eluate is either freeze-dried and the resulting impure urokinase redissolved or the urokinase is precipitated with sodium chloride or ammonium sulphate solutions or with ethanol, acetone or dioxan, then redissolved and this solution is then contacted with the synthetic cation-exchange resin which has been equilibrated with an aqueous solution, e.g. of disodium phosphate, monosodium phosphate, and sodium chloride, that has a pH between 5 and 7.5 and a cation strength between 0.1 and 1 gram equivalents per litre.  The resin was then eluted with a 0.5 molar solution of sodium chloride and the fractions containing most urokinase combined then freeze-dried to produce urokinase in solid form.  As alternatives to silica gel in the first adsorption process, barium sulphate, calcium phosphate or oxycellulose may be used.

A single phase series commutator motor which may be used for driving a locomotive is started from a D.C. supply, and, at some stage during acceleration, is changed over to an A.C. source of supply. In Fig. 1, a master controller is moved initially to increase, gradually the excitation of a generator G so steadily increasing the direct voltage applied to motors M1, M2. Further movement of the controller causes progressive reduction of the generator voltage and simultaneous increase of the alternating voltage applied to the motors through tappings of transformer 12, the generator being shortcircuited when its voltage is reduced to zero: Rheostatic braking is effected by connecting motor field windings M1f, M2f, to the generator G and placing resistor 29 across the motor armatures: The change-over from D.C. to A.C. energization of the motors may be. made by automatic speed-responsive means. In multimotor units, all the motors are started together on D.C. and, at some stage during acceleration, each motor is in turn changed over to the A.C. supply by reducing the direct voltage and at the same time increasing the alternating voltage from zero to maximum. , The Provisional'Specification refers to D.C. energization of the motors through a rectifier.

Abstract: 1501909 Simulating radio navigation signals INTERNATIONAL STANDARD ELECTRIC CORP 9 May 1975 [17 June 1974] 19619/75 Heading H4D To simulate the direct and reflected direction dependent signals received from a Doppler azimuth or elevation beacon, Fig. 1, of the rectilinearly scanned type (see Specification 1,225,190) together with the reference signal, a signal source 4, Fig. 2 (e.g. at the I.F. 30 MH 3  of the receiver to be tested) has its output divided (5) to give a reference signal channel (23) and a direction signal channel (24). The reference signal is fed, possibly with predetermined calibration or incidental phase (17) and/or identity modulation (18-21) to one input of a summer 15. The direction signal has to have an offset frequency (90 kH 3 ) with respect to the reference signal, and is therefore fed through a voltage controlled phase shifter 1 controlled by a sawtooth waveform (6 stage) D/A converter 6 receiving in turn the output of counter 42 fed with (5À76 MH 3 ) pulses from clock 41. The sawtooth has the required repetition period (<SP>1</SP>/ 90-10 3) equivalent to the offset frequency. If the amplitude weighting of the direction signal as it is commutated to the antennµ of the array is to be simulated, the direction signal (30 MH 3   90 kH 3 ) is fed through a taper modulator 7 before being split up (power divider 8) into a direct signal channel 31 and a reflected signal channel 30. To produce the "Doppler shift" equivalent to the elevation on azimuth angle to be simulated, the two signals are continuously phase shifted in respective voltage controlled phase shifters 2, 3, controlled, as phase shifter 1 by sawtooth waves from D/A converters 12, 10 fed with pulse trains 14, 34 corresponding to said simulated angle. The "Doppler shifted" signals are combined with the reference signal in summer 15 (and also with noise if required (16)) to give the final simulation.
