Abstract: 1,248,993. Measuring liquid level electrically. CONSOLIDATED AIRBORNE SYSTEMS Inc. May 19, 1969 [May 20, 1968], No. 25511/69. Heading G1N. Apparatus for measuring the level and volume of liquid in a container comprises a bridge circuit including a capacitive sensor C1, Fig. 1B (not shown) immersed in the liquid and a reference capacitor C3, the centre-tapped secondary winding of the transformer forming the remaining arms of the bridge. A compensating capacitor C2 also immersed in the liquid and connected in the feedback path between the input and output of an operational amplifier 10 corrects for variations of its permittivity. The output of the amplifier operates on indicator 18 via a demodulator 16 to allow for the progressive uncovering of a capacitor C2. The output of the demodulator is also applied via a limiter 20 to a modulator 12 to control the signal in a second feedback path including a capacitor C4 (not illustrated). By associating an external fixed podder capacitor with capacitor C2 selected in accordance with the relation between liquid permittivity and density, the apparatus is used to indicate the mass of liquid in the container. Another embodiment Fig.2A (not shown) utilizes a capacitor C2 totally immersed in the liquid and which does not become uncovered.

Abstract: 1304383 Colour television; transistor gain control circuits RCA CORPORATION 28 May 1970 [2 June 1969] 25766/70 Headings H3T and H4F An amplitude control circuit for varying the amplitude of signals in the chrominance channel of a receiver to effect a desired change in colour saturation without affecting the phase thereof i.e. without producing an undesired change in hue, comprises a chrominance amplifier transistor 20 with its base connected to the output of amplifier 14, a tank circuit 25, 26 which selects the chrominance subcarrier sideband frequencies, a series network of resistors 27 and 28 connected in parallel with the tank circuit and a transistor 30 arranged in a common base configuration with its emitter connected to the junction of resistors 27 and 28 and to the cathode of a diode 29, to the anode of which an adjustable voltage from potentiometer 38 is supplied. In operation the amplitude of the chrominance signals applied to the common base stage 30 is varied by moving the arm of potentiometer 38. It should be noted that during colour transmission the ACC detector and colour killer circuit 56 applies a negative voltage to the base of transistor amplifier 40 causing it to conduct, the voltage at the junction between resistors 38 and 39 less the voltage drop across the diode 42 establishing the bias for transistor 30 that permits linear amplification of the chrominance signals. In the absence of colour bursts the chrominance amplifying channel is disabled i.e. transistor 40 and thus amplifier 30 are cut-off. The saturation-adjusted signals developed across load resistor 32 are coupled to the emitter follower 45 and subsequently to the chrominance amplifier 50. In a second embodiment (Fig. 2, not shown) the chrominance control is provided by a field effect transistor storage network operated from a remote control receiver circuit.

Abstract: 658,770. Automatic gain control. RADIO CORPORATION OF AMERICA. Oct. 6, 1948, No. 26074. Convention date, Oct. 23, 1947. [Class 40 (v)] An automatic gain control circuit for a superheterodyne receiver for negatively-modulated television signals, i.e. signals in which peak positive modulation occurs in the synchronizing impulses, is characterized by means to prevent the bias applied to the intermediate frequency amplifier exceeding a predetermined value. A peak rectifier comprising a diode 24 with long time-constant load circuit 36, 37 is connected across the output of the I.F. amplifier 16 and the positive D.C. potential produced across resistance 36 is applied to a D.C. amplifier 44. Delay is introduced by biassing the cathode to cut-off over a potentiometer chain 46, 47, 59, the point 57 being taken to a negative supply and the anode of the valve returned to potentiometer comprising resistances 53, 52, 96, 97 connected between ground and a positive supply. A.G.C. bias for the H.F. stage is taken across the resistance 53, grid current in this stage being utilized to prevent the bias attaining positive values. The I.F. stage 112 obtains a bias from the resistance 97 which is prevented from increasing beyond a predetermined value by means of a diode 102 with its anode returned to a potentiometer 106, 108 between ground and a source of negative potential.

The front floor 25 of the heating-chamber has a longitudinal slot, which accommodates the stems 17 of the goods carriers 15, and guide grooves in which run rollers 19 on cross arms 18 carried by the stems. Each carrier consists of a base 16 with upstanding parallel bars having upturned ends 14, the bars being spaced apart to take correspondingly-spaced bars on a pivoted feed fork 13 and a slatted discharge incline 7. When the furnace is being used for billet-heating an inclined roller way is fitted above and at an angle, as seen in plan, to the incline 7 to guide the heated billets to the billet rolls.

A liquid fuel burner comprises a nozzle 1 and a deflector 12 on a bridge 13, a jet of fluid mixed with air being burnt in a toroidal ring of flame 29. Liquid fuel from pipe 16 is forced through a fine jet 21 whilst air from pipe 17 is forced through annular clearance 24 to atomize the fuel. The resulting vapour stream passes through opening 31 in wall 30 of flame pot 5 to strike deflector 12, the jet being deflected to form flame 29. The majority of the combustion air enters chamber 11 through holes 32 in wall 10 but some air enters chamber 7 through holes 33 to help prevent the vapour stream contacting the walls of a tube 2 or wall 30. Ignition is effected in chamber 7 by a spark or other igniter 34 and the burned parts are so dimensioned that there is substantially no contact between the flame 29 and wall 10. The wall 10, deflector 12 and wall 30 are of a heat resistant material, e.g. stainless steel, and form one part removably mounted on the casing 6 and tube 2 which are of mild steel. In Fig. 1, not shown, two adjacent burners have a common casing 6 divided into two by a wall.
