Title: Heat balance control of a rotary kiln
IPC: B01J6/00
Filed: 1968-03-18
Abstract: 1,219,961. Controlling furnace operation. WESTINGHOUSE ELECTRIC CORP. 18 March, 1968 [11 April, 1967], No. 12991/68. Heading F4B. [Also in Divisions G3 and H1] The operation of a rotary kiln 10 driven by a motor 12 and gear 14 and having a burner 46 is controlled and optimized by a computer 32 in dependence of the difference between the theoretical exothermic heat of reaction calculated from analysis of the raw materials e.g. sand, iron-ore, shale and lime-stone fed to the kiln and and actual heat of reaction, which is given by the difference between heat input supplied by the burner 46 and heat losses from the kiln. The difference in actual and theoretical values provides a control signal fed to a temperature controller 50 for adjusting the clinker temperature sensed by a radiation pyrometer 52 by adjusting the supply of fuel to the burner 46; the computer adjusts automatically the rotational speed of the kiln to maintain constant the position of maximum heat (burning zone) in the prescribed position within the kiln. Another control variable which may be used is the ratio of primary to secondary air fed to the burner, the total air flow being kept constant. The actual heat of reaction is evaluated as the sum of the heat inputs of the fuel and preheated secondary air less the sum of the heat losses in the clinker, in the exhaust gases, and through the kiln wall; all these quantities are measured using suitable instruments.

Title: Improvements relating to method and apparatus for producing welded seam tubing
Inventor: WILLIAMS ELMER WALTER
IPC: B23K9/025
Filed: 1955-05-05
Abstract: 770,505. Making tubes; welding by fusion; bending. TRENT TUBE CO. May 5, 1955, No. 13068/55. Classes 83 (2) and 83 (4). In order to arc weld the longitudinal seam of metal tubing, the tubing is fed with the seam below the horizontal mid-section of the tubing past a welding electrode disposed below the seam and pressure is applied to force the edges of the seam together until the fused metal has solidified. The tubing may be a stainless and corrosion resisting steel such as an austenitic chromium-nickel steel containing 17-25 per cent chromium, 18-35 per cent nickel steels containing up to 0.15 per cent carbon With or without small amounts of columbium or molybdenum, a high nickel alloy such as 15 per cent chromium and 75-80 per cent nickel or titanium, zirconium or their alloys. Strip 60, Fig. 7, is fed through a flattening guide 61 and pairs of horizontal and vertical rolls 62 which bend the edges downwardly to form a tube having a V-sectioned seam at its lowermost point. The tubing passes over a gas-shielded thoriated tungsten electrode 72 adjustably located adjacent a pair of rolls 84, 85 shaped as shown in Fig. 11 which force the opposed edges of the seam together. The electrode 72 is shielded with an inert gas such as argon or helium. A shielding gas, preferably helium with a trace of oxygen, is introduced into the tubing above the electrode from a perforated container 81, Fig. 9, connected by a pipe 80 to a gas source. The pipe 80 is supported by a bracket 91 secured to the frame carrying one of the pairs of rolls. After welding, the tubing is swaged and drawn and cut into lengths.

Title: Improvements in or relating to blind landing devices for aircraft
IPC: G01S1/02
Filed: 1940-08-16
Abstract: 568,566. Radio echo apparatus ; cathode-ray oscillographs , FORMAN, J., and PYE, Ltd. Aug. 16, 1940, No. 13077. [Class 37] Apparatus for the blind landing of aircraft comprises means for producing a potential which is variable at a predetermined rate, means for producing a second potential which is proportional to the altitude of the aircraft, and means for indicating at succeeding times the value of the second potential relative to that of the first potential at that time. The input 1 from a radio reflecting altimeter, such as that described in Specification 522,574 [Group XL], which gives a voltage varying with height, is fed through an amplifier 2 and charges a condenser 5 continuously to a voltage relative to the altitude when a ganged switch 3, 4 is in the charging position shown. On attaining correct altitude the switch 3, 4 is thrown over and causes the condenser 5 to discharge across the grid resistor 7 of a valve 9 and the amplified altimeter output to be fed through the grid resistor 6 of a valve 8. The valves 8, 9 are provided with anode load resistors 12, 13 which are connected in opposition to a centre reading meter 14 biased to zero deflection by a battery 16 and resistor 15. A cathode ray tube 17 has one pair of plates 19 connected across the resistor 6 and its other pair of plates 18 across the resistor 7. If the potentials applied to the resistors 6, 7 are equal there is no deflection on the meter 14, but if one is higher than the other a deflection occurs in the corresponding direction. The decay curve of the condenser 5 may be made to resemble the gliding curve of the aircraft when landing, so that if the plane glides in a similar curve there is no deflection of the meter 14. A representation of the landing curve also appears on the screen of the cathode ray tube 17. To enable the relative velocity of the glide to be indicated, a linearly increasing or decreasing deflecting potential is applied to the plates 18 of the tube 17 instead of the output of the condenser 5. This potential may be produced by a very low frequency sawtooth voltage generator or by a mechanically varied resistor. The spot on the screen of the cathode ray tube may be caused to disappear or defocus if the pilot goes off the landing curve. This may be effected by coils or plates arranged so as to deflect the ray and prevent it reaching the plates 18, 19 if there is a voltage across the resistors 12, 13. Alternatively the voltage across these resistors may be applied to the circuit of the focusing coil or electrode so as to defocus the ray. For short durations the contour of the underlying terrain is shown. on the screen of the cathode ray tube.
