Abstract: 1344027 Automatic control of ratio METALLURGIE HOBOKEN-OVERPELT 14 Aug 1972 [31 Aug 1971] 37841/72 Heading G3R [Also in Division C7] Apparatus for selectively controlling the oxidising-reducing nature of the combustion products of a burner 1 in a melting furnace (e.g. for Cu or Cu alloys) and hence maintaining a constant oxygen content in the molten metal, comprises conduits 4, 5 supplying gaseous fuel 6 and an oxygen containing gas 7 respectively to the burner 1. Each conduit 4, 5, has a pre-heater 10, 11 a by-pass 12, 14 having a valve 13, 15, and a further valve 8, 9, providing a constant flow of gas. In operation, an electro-chemical cell 16 dips into the molten metal and sends a signal proportional to the oxygen content to a regulator 18 which compares it with a signal proportional to the predetermined desired oxygen content from the transmitter 19. A signal proportional to the difference is sent to a control transmitter 20 and regulator 21. Transmitter 20 also sends a signal proportional to the predetermined difference in temperature of the gases 6, 7, whilst apparatus 22 measures the actual temperatures of the gases by thermocouples 23, 24. The regulator 21 acts on the valves 13, 15 according to the difference between the signals from apparatus 22 and transmitter 20. For example, if the oxygen content of the molten metal is too high, the regulator 21 raises the inlet temperature of the oxygen containing gas by acting on valve 15 and thus reduces the rate of entry of the oxygen-containing gas in moles per unit time.

Abstract: 1387646 Temperature monitoring of sewage treatment VESMAT INVESTMENTS Inc 15 Aug 1972 [18 Aug 1971 28 June 1972] 37932/72 Heading C1C [Also in Divisions C6 and C7] The bis chemical activity in systems exemplified inter alia by the disgestion of sewage or effluent in treatment plants or natural bodies of water, is monitored by measuring the temperature at two, spaced points in the system while biochemical activity is taking place between them, and controlling the biochemical activity in response to the temperature differential, as by regulating the introduction of gas (oxygen), the rate of recycled inoculum or the amount of biodegradable material in the system. Fig. 2, is a schematic view of a simplified aerobic sewage treatment plant. Raw sewage enters and flows smoothly along the length of an aeration tank 100. At and near the admission point 102 the adsorption of organic material on the surface of the bacteria is the principal action Further downstream there is the log rate of microbial growth and, finally, a declining rate of growth. The fermented liquid then passes into a quiescent settling tank 104 where growth continues some what with the resulting rapid formation of floe which settles to the bottom of the tank in the form of sludge, usually a light sludge blanket 106 on top of a heavy sludge blanket 108. The sludge is drawn off and at least a portion is returned to the aeration tank, as at 110. The supernatant liquid (effluent) 112 flows continuously from the upper portion of the settling tank 104. According to the invention a control system 14 is used for adjusting the rate of air input and the rate of sludge return by means of solenoid-operated valves 116 and 120, respectively. Fig. 8 (not shown), is a schematic view of a telemetric monitoring and control system for three sewage treatments plants discharging effluent into confluent streams or rivers. Fig. 9 (not shown), is a flow diagram of a small sewage treatment plant comprising four aeration tanks (132, 134, 136 and 138), two sludge digesters (154 and 156) and two sludge separators (146 and 148), which may be monitored and controlled according to the principles of the invention.

Abstract: 1484948 Gas turbine ducted fan engines ROLLS-ROYCE (1971) Ltd 4 Sept 1975 [7 Sept 1974] 39181/74 Headings F1C and F1J The invention relates to a gas turbine ducted fan engine having a variable pitch fan which is driven through a reduction gear, the pitch of the fan blades being adjustable by means of a motor which rotates with the fan about the axis thereof. In the engine shown the fan comprises blades 12 mounted on a fan rotor 28, 29 which is secured to the shaft 23, the shaft 23 being driven by a main shaft 22 through epicyclic reduction gearing 25; a sun gear 24 formed on the shaft 22 engages planet pinions 25 mounted on a planet carrier 26 secured to the shaft 23, the planet pinions engaging an internal ring gear 27 secured to stator structure. The fan blade actuator motor is indicated at 30 and is of the radial vane type operated by high-pressure fluid; the motor drives bevel gears 32 one mounted on each fan blade, the outer casing of the motor being connected to the shaft 23 so that the motor rotates with the fan. The inner casing of the motor is connected to an auxiliary shaft 34. When the motor is actuated the inner and outer casings rotate relative one to the other so that the auxiliary shaft 34 rotates relative to the shaft 23 and this is utilized to provide an indication of the degree of pitch change. The shaft 23 is connected through the planet carrier 26 to a sleeve 35 mounted for rotation in bearings 48, 49 and carrying a ring gear 36 at its free end. An intermediate pinion 37 engages with the ring gear 36, the pinion 37 engaging also a gear 39. The inward end of the auxiliary shaft 34 carries a gear 43 which drives a shaft 46 through pinion 44, the shaft 46 passing between the planet pinions 25. The shaft 46 carries at its other end a gear 45 which engages a ring gear 47 supported on the bearings 48, 49. A gear 50 engages with the gear 47 and is mounted on a shaft 38 whereby a gear 50A is driven, the gear 50A engaging a pinion 41. A gear 40 freely mounted on shaft 38 engages the gear 39, also the pinion 41. The pinion 41 is mounted on a swinging link 42 freely mounted on the shaft 38, the link carrying a bevel pinion 51 which engages a bevel pinion 52 mounted on a shaft 53 which drives an indicator. Thus movement of the blade actuator motor causes relative rotation between the gears 50A and 40 and so movement of the gear 41 and thus of the link 42, the movement being shown on the indicator.
