Title: Improvements in or relating to oil-burner installations
IPC: F23K5/00
Filed: 1947-11-14
Abstract: 636,643. Liquid fuel burners. RUTHERFORD, E. J. Y., and JACKSON, G. J. Nov. 14, 1947, No. 30269. [Class 75 (i)] In an oil burner installation having a burner a in which fuel is atomized by steam, with an auxiliary atomizing agent for starting purposes an automatic control valve c<SP>1</SP> is provided to allow oil to pass to the burner only when a suitable pressure is established in a tank d which supplies water to the steam generator producing steam for atomizing the fuel. Water supplied at a desired head to tank d from cistern f through pipe f<SP>2</SP> and three-way cock g compresses air into the upper portion of tank d. Upon opening valve e<SP>1</SP> in pipe e, the compressed air flows to the steam generator elements in burner a, and, at the same time operates valve c<SP>1</SP> to allow oil to pass from tank b to burner a where it is atomized by the compressed air and ignited by a pilot jet supplied by a pipe i<SP>2</SP>. As the burner becomes sufficiently heated for the generation of atomizing steam the volume of air in tank d will diminish, the water level will rise and compressed air and water, and finally water will flow along pipe e to the burner. In the event of water supply failure, the water level and pressure in the tank d will fall to cause valve c<SP>1</SP> to cut off the fuel supply to the burner a. The automatic control valve c<SP>1</SP> comprises a valve l<SP>1</SP>, Fig. 2, pressed on a seating I by a coiled spring, and is operated by a bellows o which is exposed to the water pressure. A cam g<SP>3</SP> fitted to the threeway cock g opens a snifting valve h when the cock is turned to the draining position. A safety device may be fitted to cut off the fuel supply in the event of the burner being extinguished. This device comprises a tray k which, upon collecting sufficient unburnt fuel from burner a, causes lever j<SP>2</SP> to drop, to release arm j<SP>1</SP> so closing valve j to shut off the fuel supply. A thermostatic device may be fitted to operate a poppet type three way cock Fig. 3 (not shown) according to the room or boiler temperature. Specification 383,016 is referred to.

Title: Low liquid level warning system
IPC: G01F23/36
Filed: 1970-06-23
Abstract: 1286401 Measuring liquid level electrically FORD MOTOR CO Ltd 23 June 1970 [10 July 1969] 30375/70 Heading GiN In a low liquid level warning system a warning device is energized when the amount of electrical energy of pulses applied to a pulse integrator connected to the warning device falls below a predetermined level corresponding to the low liquid level. The Fig. shows the system applied to a motor vehicle petrol tank 64 and a pulsating voltage produced by bi-metal instrument voltage regulator 36 energized from vehicle battery 16 or alternator 12 appears at junction 100 between gauge 52 and variable resistor 60 of the liquid level detector. The instantaneous magnitude of the pulses at point 100 increases as the level of the liquid 66 falls due to the increase in resistance tapped off by wiper 70. When the liquid level is above a critical level the voltage of the pulses applied to the emitter of transistor 77 is more negative than the voltage of pulses at point 88 connected to the base of this transistor, the voltage at point 88 being dependent upon the value of resistors 85, 86 and the supply voltage on line 30 and produced by the switching on and off of transistors 75, 76 by the pulses at junction 100. Under these conditions transistors 77 and 78 conduct to apply pulses to pulse integrator relay 84 via line 112. The integrator 84 is in the form of a bi-metallic strip 124 and heater winding 116 and after a given amount of electrical energy is received by winding 116 bi-metallic strip 124 bends upwardly and opens contacts 130, 132 to deenergize warning lamp 82. If the liquid level falls below the critical value the magnitude of the pulses at point 100 is such that the emitter 98 of transistor 77 becomes more positive than the pulses at point 88 and transistor 77 becomes non- conducting. This cuts off transistor 78 and hence the supply of pulses on line 112 to the integrator winding 116. The bi-metallic strip 124 cools down and makes contacts 130 and 132 to energize the warning lamp 82.

Title: Improvements in and relating to the production of ethanol
IPC: C07C29/04
Filed: 1949-12-01
Abstract: <PICT:0691360/IV (b)/1> Ethanol is obtained by the direct catalytic hydration of ethylene by reacting ethylene and water at 250 DEG  to 350 DEG  C. and at a pressure of 200 to 500 atmospheres over a solid hydration catalyst consisting of the blue oxide of tungsten, using a feed rate of water in the range from 0.05 to 3.0 litres per hour per litre of catalyst bulk space and a feed rate of ethylene such as to maintain the total reaction pressure constant by compensating for any loss of ethylene from the reaction zone, and removing only the liquid phase from the reaction zone.  The pressure on the liquid leaving the reaction zone may be reduced in stages down to atmospheric pressure and the liquid may be taken to a heat-exchanger where it may serve to preheat the water or the water and the ethylene to be reacted.  The liquid may then be passed to a still where the ethanol is recovered as an azeotrope with water and this azeotrope may be subjected to further azeotropic distillation, e.g. with benzene to recover substantially pure ethanol whilst the water withdrawn from the still may be recycled to the reaction zone.  The catalyst is preferably one of the unsupported type in the form of pellets and may be prepared from tungstic acid as described in example 2 of Specification 622,937, and this form of catalyst is employed in the examples given in which the process is carried out at 300 atmospheres pressure at temperatures of 300 DEG , 320 DEG  and 345 DEG  C. respectively, using a feed rate of 1 litre of water per hour per litre of bulk space occupied by the catalyst and in an example in which the process is carried out at 300 DEG  C. and 300 atmospheres pressure with various water feed rates.  The process may be effected in the plant illustrated in the Figure, wherein 1 is a converter containing a catalyst charge 2, ethylene being introduced via a compressor system 3 of one or more stages whilst water is introduced by way of compressor pump 4.  The ethylene and water are both compressed to the desired pressure, e.g. 300 atmospheres and are then passed countercurrently to the liquid withdrawn from the bottom of converter 1 and exchange heat with the liquid.  The water and ethylene then pass through a preheater 6 where they are raised to the operating temperature, e.g. to 300 DEG  C. and the mixture then passes to the converter 1.  The pressure is kept constant by regulating the flow of ethylene into the converter by means of a valve on the ethylene inlet line.  The liquid from the converter then passes through the heat exchanger 5 as stated into catch pot 8 where some of the dissolved ethylene flashes off and may be recycled to compressor 3.  The pressure is finally let down to atmospheric by valve 10 and the liquid then enters a still 11 heated by a steam coil.  An azeotropic water-ethanol mixture is passed through a condenser 13 to catchpot 15 where a small quantity of ethylene flashes off and may be recycled. Water leaving the bottom of still 11 may also be recycled to the process via pipe 17.
