Patent GB-881214-A (GB)
Title: Improvements in or relating to electrical amplifiers
IPC: G01R17/08
Filed: 1959-12-18
Abstract: 881,214. Electrical measuring instruments. LANDIS & GYR A.G. Dec. 18, 1959 [Dec. 20, 1958], No.43091/59. Class 37. In a galvanometer feeding arrangement a feedback derived from the current to be measured, and a first and at least another higher derivative thereof with respect to time are developed and applied to the galvanometer in opposition to the current to be measured. The arrangement, which provides damping without considerable delay, is applied to a telemetry receiver in which a train of pulses incoming to a relay 17 effect the actuation of a galvanometer 23 in accordance with the pulse frequency. Condenser 27 which is charged to a predetermined voltage from terminals 15, 16 on receipt of a pulse, falls away to send a current I through the galvanometer on cessation of the pulse. An orifice 28, Fig. 3, in a disc 29 driven by the galvanometer movement changes the amount of light from a source 31 falling on a photocell 32 to increase the current to anode 42, part of which I21 passes through the galvanometer coil. The first derivative 13 is developed by the fall of potential of anode 42 through capacitor 46, and the second derivative 14 by the change in potential of anode 51, resulting from the common cathode resistor 41, being applied over condenser 53 to an amplifier stage 55.

Abstract: 1418584 Agitating and aerating liquids AUTOTROL CORP 18 Sept 1973 [29 Sept 1972] 43796/73 Heading B1C [Also in Division Cl] In a process for the purification of waste water it is supplied to a tank having a plurality of partly submerged rotatable biological contact surfaces therin at a rate of 0.4 to 2.5 gal/ day/sq. ft of effective contact surfaces, and the contactors rotated at such a peripheral velocity that nitrogenous and carbonaceous pollutants are simultaneously oxidized in a single stage. The preferred waste water supply rate is 0.4 to 1.5 gal/day/sq. ft which can be increased if the tank be enclosed and the atmosphere therein enriched to 30%-60% oxygen. A plant, Fig. 3 (not shown) comprises a screen (10), a settling tank (11), a surge tank (12), a single-stage treatment tank (13) and a further solids separator (14). In a modification Fig. 5 (not shown) there may be an additional, denitrifying tank (23) upstream of the single stage tank (13) and treated water may be recirculated to it. The de-nitrifying tank is of the same construction as the single-stage treatment tank but the growth of the de-nitrifying slurries is encouraged by fully submerging the contact surfaces to deprive them of atmospheric oxygen; a controlled amount only may be supplied to prevent anaerobic conditions. The rate of flow, not including recirculated flow, to the de-nitrifying unit is preferably 4-16 gallons/ day/square foot of de-nitrifying unit contactor surface.  A treatment tank 24, Fig. 6 has rotatable contact discs 25 and may be divided by partitions 37-39 into separate chambers 33-36 connected to inlet and discharge manifolds 31, 32 whereby they may be selectively operated. The contact discs are 10 to 12 feet in diameter, spaced # inch to 1 inch apart, and rotated with a peripheral speed of 0.25 to 1 ft/sec. Preferably they are of honeycomb structure as described in Specification 1392552.

A pulverizing mill comprises a cylindrical casing 10 rotatable about its horizontal axis, having an inlet opening 14 and an outlet opening 15, a plurality of coaxially arranged and axially spaced rolling races 11, formed within the casing to support a corresponding plurality of disc-shaped grinding members 13, means to direct an air-stream through a passage 20 into the inlet opening and through the mill, and inwardly projecting members, which may be, e.g., scoop-shaped hollow projections 21, arranged along the contour of each crown between each pair of races 11. When the casing is revolved the material, fed from hopper 18 along path A1, is ground by corresponding rotation of the discs. The ground material is lifted by the scoops to the upper part of the mill, and when it falls from the scoops the amount by which the air-stream deflects the material downstream and into the succeeding grinding sections is determined by the particle size of the material.
