Title: A combustion control apparatus
IPC: F23N1/02
Filed: 1966-11-24
Abstract: 1,095,609. Automatic mixing control. WESTINGHOUSE ELECTRIC CORPORATION. Nov. 24, 1966 [Dec. 20, 1965], No. 52578/66. Heading G3R. [Also in Divisions F4 and G1] Automatic mixing control apparatus comprises lines 17 and 23 supplying fuel and air to a furnace 11, and an oxygen solid-electrolyte cell 111 which samples the flue gases or the fuel and air entering the furnace, the magnitude of the electrical potential produced by the cell adjusting the ratio of fuel to air. The cell comprises a tube 113 of the electrolyte coated inside and out with porous platinum to which electrodes are connected. When the cell is heated by a furnace 119 and the difference in partial pressures of the oxygen in the atmosphere outside the cell and the oxygen in the flue gases within the cell produces a potential amplified at 141. The signal received by controller 143 is compared with a potential corresponding to a desired flue gas oxygen level and any difference detected causes a motor 147 via shafts 149 and 151 to adjust the position of the fulcrum 35 of the lever 33 of a proportioning meter 31. If an increase in combustion oxygen is required pinion 37 moves to the left and the lever is pivoted to close contacts 75 and 79. A motor 25 which controls a damper in the air line 23 is energized so that the air-flow is increased. Pairs of bellows 41, 43 and 45, 47 are provided at the ends of lever 33 and the bellows of each pair are connected either side of a diaphragm 51, 53 in the fuel and air lines respectively. An increase in the flow of air to the furnace caused by the energization of motor 25 will cause the lever 33 to resume its horizontal position and open contacts 75, 79. A fluctuation in either the air or fuel pressure will cause the lever 33 to pivot thereby closing contacts 75, 79 or 77, 81 and energizing the motor 25 to increase or decrease the air-flow so that the fuel/ air ratio remain constant.

Title: Apparatus for dehydrating organic liquids
Inventor: REID LAURANCE STANDISH
IPC: C10G33/06
Filed: 1969-10-30
Abstract: 1282494 Dehydration of organic liquids such as glycols L S REID 30 Oct 1969 [21 Nov 1968] 53249/69 Heading B1B An organic liquid which contains moisture, such as triethylene glycol which has been used to dry natural gas, is dehydrated by feeding the hot liquid through inlet 12a into one end of a vessel 12 wherein the water vaporizes (together with some of the glycol) into space 16 as the liquid flows round baffles 18, 20 to the other end of the vessel. The vapour flows through conduits 32 and condenses on cooled U-tubes 34, the condensate being collected in sump 44. Dry glycol is withdrawn from vessel 12 through outlet 12b. Some of the glycol reaching the left-hand end of vessel 12 is recirculated to the right-hand end through conduit 22 by means of propeller 24. Wet glycol from the gas-drying system is passed through U-tubes 34 by means of inlet 38a and outlet 38b. The wet glycol next flows via conduit 48 to heat-exchanger 50 in distillation column 52, and then flows via conduit 56 to coil 58 where the temperature of the glycol is raised to about 330‹F by heat-exchange with dry glycol taken from the outlet 12b of vessel 12. The hot wet glycol is introduced through conduit 66 and nozzle 68 into column 52 wherein it flows down over packing 70 to sump 72 and reboiler 76 which is heated by fire-tube 74. Most of the water vaporizes from the liquid in the reboiler, and the vapours flow to the column through conduit 80. Glycol, containing only a small amount of water, is withdrawn at a temperature of about 350‹- 375‹F from the reboiler through conduit 82, and is then introduced into vessel 12 through inlet 12a. Non-condensable gases are withdrawn from the condenser through conduit 88 by pump 86 which delivers the gases via line 94 to the nozzle 68 of column 52. Condensate from sump 44 is delivered by pump 98 to nozzle 68. Gases and water-vapour are discharged from the column through vent 52a. The liquid-level in sump 44 is maintained constant by means of bypass line 104 and valve 106 controlled by a float mechanism 108 which also controls pump 86. Apparatus is disclosed (Fig. 3, not shown) wherein the vapours evolved in vessel 12 are withdrawn therefrom by means of an eductor pump operated by the power of wet glycol. The effluent from the eductor pump is supplied to the heat-exchanger in the top of the distillation column. Reference is made to the dehydration of propane, alcohols, ethers, and hydrocarbon fuels.

Abstract: 1,149,749. Automatic speed control. TRANSISTOR A. G. Nov.29, 1966 [Dec.1, 1965], No.53372/66. Heading G3R. [Also in Division H2] A commutator motor 1 is supplied from A.C. source 3 through thyristor 2 which is conductive during each positive half-cycle of the source voltage when transistor 8 is non-conductive. If the voltage of tachometer generator 10 exceeds a reference voltage derived from potentiometer 12, the transistor becomes conductive and diverts current from the gate of the rectifier 2. The motor circuit remains open until the reference potential again exceeds the tachometer voltage. The firing circuit is supplied with pulsating voltage from a phase-shifting network comprising diodes 15, 16, associated with resistors 13, 14 and capacitors 17, 18. In a modification, a series-wound motor is coupled to a tacho-alternator comprising a permanent magnet on the motorshaft co-operating with a centre-tapped stationary winding whose output is rectified. The potentiometer 12 is in series with a resistor shunted by a switch for varying the speed-range. Chokes and capacitors prevented radio interference.
