Title: Improvements in pulse generators
IPC: H03K3/78
Filed: 1961-03-29
Abstract: 899,570. Pulse circuits; pulsing carrier frequencies. SVENSKA RELAFABRIKEN A.B.N., A.B. March 29, 1961 [April 2, 1960], No. 11577/61. Classes 40(5) and 40(6).  A circuit for generating trains of pulses comprises a valve or transistor multivibrator in which the control electrodes are each connected via a resistor and a diode in parallel to a capacitor so that the circuit behaves as a squegging oscillator. In the circuit shown, capacitors C2, C3 alternately discharge via diodes D1, D2 into the much larger capacitor Cl during the respective half cycles of oscillation when transistors TR1, TR2 are conductive. When the charge on capacitor Cl is sufficient to cut off the transistors TR1, TR2 oscillation ceases until Cl has discharged via resistors R4, R5, R6 and the transistor leakage current, when oscillation restarts. The amplifying transistor TR3 is biased off by the voltage across C1 before the oscillation ceases and hence has a gating effect on the oscillator output.

Title: Waste-water purification
IPC: C02F3/12
Filed: 1973-03-09
Abstract: 1402369 Purifying waste water STERLING DRUG Inc 9 March 1973 [24 March 1972] 11646/73 Heading C1C Simultaneous removal of organic carbonaceous material and biological oxidation of the reduced nitrogenous forms in waste waters followed by subsequent reduction of the oxidized nitrogen to elemental nitrogen is achieved by a process which comprises (a) introducing an aqueous suspension of an adsorbent capable of adsorbing organic carbonaceous material while simultaneously adding oxygen or a free oxygencontaining gas to a vessel (2, Fig. 1) containing waste water and a developing active biomass having a sludge age of at least three days; (b) maintaining aerobic conditions for a length of time sufficient substantially to oxidize the ammoniacal nitrogen to nitrite or nitrate nitrogen; (c) settling and separating (at 7) the adsorbent, associated adsorbed organic material and biological solids and returning separated solids (8) to the vessel; (d) passing the liquid phase (13) to an anaerobic denitrification zone to which further adsorbent (16) and a source of organic carbon (17) is added whereby the oxidized nitrogen forms are reduced to elemental nitrogen and (e) passing the mixture to a quiescent zone (21) where the adsorbent and associated organic material are substantially removed from the waste water. The adsorbent may be clay, fly ash or preferably powdered activated carbon and the source of organic carbon is preferably methanol. Adsorbent and adsorbed organic material (18) may be transferred from step (e) to the aerobic zone (b), preferably at the rate of accumulation in step (b). A portion of the solids separated in step (c) may be removed for subsequent regeneration or disposal at such a rate as to maintain an approximate materials balance. Where the waste water is sewage it may be subjected to primary sedimentation prior to the initial treatment with adsorbent. The sludge obtained from primary sedimentation may be conditioned by thermal methods or wet air oxidation, dewatered, the liquid phase treated with lime to a pH of greater than 8À0, the ammoniacal nitrogen stripped off and the resulting liquid fed to the anaerobic zone (d) to reduce the quantity of organic carbon required. Alternatively lime may be added in the primary sedimentation step, the sludge conditioned and dewatered, ammoniacal nitrogen stripped from the liquid phase and the liquid fed to the anerobic zone (d). Caustic may be used instead of lime. Optionally, after the aerobic zone (b) and/or the anaerobic zone (d) and before settling, the mixture may be passed to a flocculation zone (5 or 15) where a polyelectrolyte (6) is added. Regeneration of the adsorbent in the system may be carried out by removing a portion (10) of the solids in the aerobic zone, regenerating in a regenerating system (12) and returning to the system. A precipitant, such as a source of ferric or aluminium ions, may be added to the raw sewage before treatment.

Abstract: 581,976. Wave guides; superheterodyne receivers. CORK, E. C., MANIFOLD, M. BOWMAN-, GALE, F. H., and BLYTHEN, R. Sept. 1, 1942, No. 12351. [Class 40 (v)] An arrangement for mixing high-frequency oscillations, for example in superheterodyne reception of waves transmitted through wave guides, comprises a mixing element supported in a tubular conductor having inner conductors for feeding the respective oscillations to opposite ends of the mixing element, which may be a crystal. The waves arriving on a wave guide 1 are picked up by a disc 6 on a hollow rod 7 telescopically associated with an inner rod 3 to which one terminal of the crystal 2 is connected. The local oscillation source feeds a concentric line 15, 20, the inner member 15 of which is coupled by a capacity 17, 18 to the opposite terminal of the crystal 2. The resultant oscillations are taken off by a line 10 connected to the rod 3 and passing through a piston tuner 24, 11. The slidable piston 24 is separated by dielectric 23 from the cylinder 11 to form a capacity large enough to shunt the input waves and allow only the resultant of difference frequency to pass outwards along the line 11. A further piston tuner 13, with a short-circuiting piston 22 is provided for impedance matching. The crystal is enclosed by a tubular conductor 9, 16 integral with the tuning cylinders, the whole being slidable on the outer conductors 4, 20 of the wave feeders, to permit adjustment of the capacity 17, 18. Access to the crystal is obtained by a removable plate covering the opening 21.
