Title: Improvements in thermionic valve voltmeters
IPC: G01R19/00
Filed: 1945-05-10
Abstract: 600,276. Thermionic valve voltmeters. MARCONI'S WIRELESS TELEGRAPH CO.,. Ltd., and NEILSON, P. J. May 10, 1945, No. 11747. [Class 37] A valve voltmeter includes a multi-electrode valve so connected that the application to one of its electrodes of the voltage to be measured causes a simultaneous and opposite change in current to two of its other electrodes, and a current or voltage measuring instrument connected across the last-mentioned electrodes so as to indicate the resultant change. In the arrangement shown a pentode V has its cathode connected through a resistor RC to the nega. tive terminal of a source of anode current, the first grid being connected to an adjustable tapping on the resistor RC. The second grid is connected to the anode through series-connected resistors R, S,. the junction of which is connected to the positive terminal of the source of anode current, the potential of which may be 140 volts. The voltage to be measured is applied to the third grid and cathode with its negative terminal to the grid. An indicating meter M is connected across the resistors R, S. The adjustable tapping on the resistance RC enables the measuring instrument to be zeroized. The pentode V may be replaced by a pentagrid valve, the second and fourth grids of which are connected together and to the lower end of the resistor S, the third grid being connected to the negative terminal of the voltage to be measured.

Patent GB-142806-A (GB)
Title: Improved manufacture of resin from naphthas
IPC: C08F240/00
Filed: 1920-04-28
Abstract: 142,806. Barrett Co., (Assignees of Dennis, C. M.). May 5, 1919, [Convention date]. Tar oils, purifying.-In the production of resin from solvent naphthas, a starting-material containing 30 per cent resin-forming constituents is produced by diluting a naptha containing a higher percentage with one containing a lower percentage of these constituents. The Specification as open to inspection under Sect. 91 (3) (a) describes also the production of a light-coloured resin by subjecting the naphtha, with or without this initial blending, and after removal of tar acids and pyridine by means of alkali and acid respectively, to a preliminary polymerization by means of sulphuric acid, say 0.1 to 0.5 per cent of acid of 60 to 66 BÚ., whereby darkcoloured constituents are removed, and then after neutralizing and distilling the oil the main polymerization is effected by means of sulphuric acid, say 1 to 3 per cent of about 62 BÚ. The spent acid and tar are removed from the resin-containing oil in a settling-tank, the oil is then neutralized with alkali, washed with water and distilled in vacuo. A final distillation in vacuo with introduction of superheated steam removes napthalene and heavy oils and produces a hard resin. The process may be carried out in the plant shown. The crude naphtha is pumped first to a tank 3, containing a stirrer and cooling-coils and proyided with a double bottom for heating or cooling; there it is treated with soda solution to extract phenols, dilute acid to remove pyridine, and subjected to the preliminary polymerization with sulphuric acid. The acid-free neutralized oil is then pumped to a still 16, where it is distilled in vacuo by means of heat from a steam-coil 17 ; the distillates pass to a condenser 21, thence to receivers 22 and a storage tank 31. The oil from the tank 31 is pumped to a vessel 33 provided with a stirrer and heating-coils, where the main polymerization is effected by sulphuric acid supplied from a tank 34. The product is then pumped to a settling- tank 43, wherein it is neutralized with soda and washed with water, and passes to a still 44 similar to the still 16, and the still liquid residue from here is subjected to the final distillation in a still 58. The naphthas distilled off from the still 44 and the heavy oils from the still 58 are condensed and collected in recesses 59, 60, 61, and pass to storage tanks 62, 63, 64, while the molten resin is drawn off from the bottom of the still 58. This subject-matter does not appear in the Specifica. tion as accepted.

Title: Electrical servo-system operating on an extended speed range
IPC: G05D1/08
Filed: 1962-03-28
Abstract: 988,794. Measuring pressure electrically. BENDIX CORPORATION. March 28, 1962 [April 4, 1961], No.11937/62. Heading G1N. In a closed loop servo system wherein a control signal from a transfucer is fed through an amplifier to a servomotor to electromechanically rebalance the system, an electrical anti-hunting feedback signal is derived from a rate generator coupled to the servomotor, the mechanical characteristics of the combination being such as to produce proportionately more feedback at low levels of the control signal than at higher levels. As shown (Fig. 1), a bellows 4 measuring ambient atmospheric pressure to give an indication of the altitude of an aircraft, is mechanically coupled to the armature of an E-shaped pick-off 13 producing a signal from the secondary windings 18 which is amplified to energize a servomotor 103, repositioning the E-shaped core 19 of the pick-off 13 to eliminate the control signal. The motor 103 is also coupled to a rate generator 111. For low values of the control signal, the speed of the motor 103 and the output from generator 111 are both proportional to the control signal, giving a high feedback voltage producing high damping. As the motor speed reaches its maximum value, the incremental change in feedback voltage is considerably reduced, thereby reducing the value of the damping. The initial high damping value is adjusted by a variable resistance 130 in the feedback loop.
