Title: Improvements in or relating to tuned circuit arrangements
Inventor: MARSHALL RICHARD SYDNEY
IPC: H03J3/06
Filed: 1967-06-02
Abstract: 1,216,308. Variable reactance circuits; transistor amplifying circuits. PLESSEY CO. Ltd. 24 May, 1968 [2 June, 1967], No. 25491/67. Headings H3R and H3T. In an arrangement in which a circuit is tuned over a band of frequencies in dependence upon an applied tuning voltage, by means of a varactor diode, compensation means are provided for producing selective damping of the tined circuit so that the loaded Q-factor remains substantially constant. In a U.H.F. circuit, inductor L, Fig. 3, is tuned by means of seriesconnected varactor diodes VD1, VD2 which obtain a variable bias from control source 1 via feed-through capacitor C1 and resistor R1. In such an arrangement the Q of the varactor diodes VD1, VD2 and hence of the circuit varies over the tuning range. To compensate for this and provide a constant Q a PIN diode D1 is connected to a tap on inductor L and obtains a variable bias from control source 1 via a network comprising feed-through capacitor C2, series resistor R5 and potentiometer R3, R4. PN diodes D2, D3 in conjunction, if necessary with a resistor Rd modify the control voltage on diode D1 relative to that supplied by control source 1 in such a manner as to provide the necessary compensation as the frequency is changed. In a simplified alternative (Fig. 2, not shown) the resistor in series with diode D1 is made of high value and is directly connected to the control source 1. In another embodiment comprising an R.F. amplifier with transistor T1 having varactor-diode tuned circuit L, VD1, VD2 as its collector load, the collector circuit includes a network 4 simulating a frequency-dependent resistance. Network 4 comprises a resistor in series with a length of line, taking the form of a coiled-up inner element inside a tubular outer element and which is effectively short-circuited at the remote end; the effective length of the line varies from near a quarter wavelength to near a half wavelength over the tuning range.

Sept. 11, 1931, No. 25564. Convention date, Sept. 17, 1930. [Class 40 (v).] An amplifier to operate an ultra-short wave comprises a valve with its grid at a high positive and its anode at a negative or low positive potential. The Figure shows a transmitter comprising oscillator O, modulator M, amplifier A and radiating system RA. The oscillator comprises push-pull valves 2, 4 having their grids and anodes connected by lines 6, 8 which are tuned by having their effective lengths varied by trombone-like slides 10, 18. Anode and grid potentials are applied at voltage nodal points, and to start and maintain oscillations a " catalyst " element 22 comprising a metal strip one-half wavelength long coupled to the anodes is provided. A similar arrangement is employed for the amplifier which is provided with neutralizing elements 42, 44 to prevent self-oscillation. Grid bias to the amplifier is fed through a loop 32 one-quarter wavelength long. The lines connected to the valve input and output circuits are arranged closely adjacent to one another to avoid radiation. The output is applied through blocking condensers 62, 64 to an aerial 60. In the receiving system, Fig. 2 (not shown), similar amplifiers are used and similarly arranged valves are used as detectors.

Abstract: 738,455. Glass manufacture. GILLBERG, E. G. R. Sept. 22, 1953, No. 26135/53. Class 56. A method of manufacturing pane glass according to the Fourcault method is characterized in that the drawing bar 6, made of steel instead of the more usual fire brick, is cooled by controlling a cooling medium passing through channels 12, 13, and 14 so that the molten glass coming into contact with the drawing bar during the glass drawing operation never reaches a temperature corresponding to the maximum crystallization rate of the glass. The drawing bar 6, made of heat-resisting steel and comprising two identical parts 7 connected at their ends by vertical pivots, is introduced cold into the drawing chamber 2 of a melting furnace 1 where it is heated by radiation until it reaches the temperature inside the chamber 2. The bar 6 is then immersed into the molten glass until the latter rises approximately up to a finely-polished delivery slot 11 in the bar, the thickly flowing layer 17 of molten glass forming a protective layer around the lower part of the nozzle. At the commencement of the glass drawing operation the bar 6 is forced down into the molten glass 16, a quantity of which is urged upwardly to be caught with a rake and led upward between rolls, the bar being cooled to such an extent that no glass sticks around the slot 11. This is ensured by maintaining the temperature of the molten glass adjacent the bar 6 at a temperature not higher than 925‹ C. for glass of the customary composition.
