Inventor: THOMPSON DONALD GEORGE
IPC: G05F1/573
Filed: 1962-01-02
Abstract: 947,953. Automatic voltage control systems. MULLARD Ltd. Jan. 2, 1962; No. 153/62. Heading G3R. [Also in Division H3] In a television receiver employing transistors, the line scan output stage is protected from excessive dissipation should the drive fail, by supplying the line scan circuit from a voltage stabilizer of the series transistor type and biasing the stabilizer from a high tension supply derived from the line output stage so that a failure of the high tension cuts off the series transistor. The line scan circuit, not shown, is supplied through the emitter follower T1, which is controlled by the voltage error detector T3 and error amplifier T2. The collector load R3 of detector T3 is a high value resistor connected to the high tension supply which is derived from the output of the line scan circuit. An initial bias is obtained from capacitor C1 to enable transistor T1 to conduct before the high tension supply has built up. In a modification, Fig. 2 (not shown) a rectifier is connected in series with capacitor C1 to prevent unwanted ripple from being injected into the control circuit.

Title: Improvements in and relating to direct current amplification systems
IPC: H03F3/40
Filed: 1950-01-05
Abstract: 667,255. Valve amplifying circuits. BRITISH THOMSON-HOUSTON CO., Ltd. Jan. 5, 1950 [Jan. 22, 1949], No. 315/50. Class 40 (vi). An amplifier for unidirectional signals comprises a thermionic valve with a common cathode arranged to produce two independent electron streams, two anodes and at least two control grids, connected so that the sections of the valve form adjacent arms of a bridge circuit connected between points of balanced potential, a transformer connected between the balanced points, a square-wave power supply connected to the bridge, and means for varying one of the electron streams in accordance with the signal so as to produce an alternating output in the transformer. As shown, Fig. 1, a double multi electrode valve 1, having a common filament and preferably of the double electrometer type having a common spacecharge grid and separate control grids and anodes, and low operating potentials, is connected to the balanced points X, Y of a bridge circuit. The anode resistors 9, 10 form the balancing arms of the bridge, and a balancing resistor 8 is connected between one section of the valve and the balance point Y. A squarewave supply source 19 is connected across the diagonal of bridge between the junction of load resistors 9, 10 and the common cathode of the valve, and the primary winding 22 of a transformer is connected across the other diagonal. Bias potentials for the control grids and the common space charge grid are taken from tapping points on resistors 12, 13 connected in series with the filament across a battery 11. The bridge is set up by connecting a battery 35 to give a D.C. potential equal to the peak amplitutde of the square wave in place of the square wave supply 19. The bias voltages applied to the grids are then adjusted to give equal potentials at the balanced points X, Y. The bias applied to the space charge grid is so chosen that any variations in emission between the two sections of the filament are compensated by a redistribution of the potential minima between the space charge grid and the cathode. The secondary 24 of the output transformer is tuned to the repetition frequency of the square wave supply, so that an alternating current of this frequency and of amplitude corresponding to the D.C. input applied across resistor 15 is obtained. In a modification, Fig. 2 (not shown), a valve having screen grids is used, by-pass condensers are provided between the screen grids and earth, and balancing condensers are connected between the balance points of the bridge and earth.

Abstract: 1410541 Concentrating biological heatsensitive substances BAYER AG 4 Jan 1973 [1 Feb 1972] 497/73 Heading B1G Solutions of biological heat sensitive substances selected from enzymes, enzyme-inhibitors, natural or synthetic antibiotics, and intermediate products used in the production of antibiotics are concentrated by (i) cooling the impure solution to produce two separate portions consisting of a frozen impure solution a cooled impure solution (ii) mixing product (i) with ice to form pure ice crystals and a first concentrated solution and (iii) separating the pure ice crystals from the concentrated solution. The production of the frozen solution is preferably effected in a rotary cooling device at about -40C. The process also includes (iv) further cooling the concentrated solution to form ice and a second concentrated solution and (v) separating ice from step (iv) and recycling the latter to step (ii). Specified substances are kallikrein, hyaluronidase, asparaginase, kallikein-trypsin inhibitor, pancreas extracts, 6-aminopenicillanic acid and semi-synthetic penicillins manufactured therefrom. The process may be carried out batchwise or continuously.

After completion of recrystallization in 3, pure ice crystals are separated from the first concentrated solution 12 in the first separating device 4. The recycled pure ice 11, is used to pre-cool impure solution 10, in the pre-cooler 1 and is then discarded. The first concentrated solution obtained is fed to device 5 wherein it is further concentrated and separated in device 6 into concentrated solution 13 and ice crystals.
