Title: An improved oil burner and fuel feed system for same
IPC: F23C99/00
Filed: 1947-12-16
Abstract: 644,089. Liquid-fuel burners. HUSBAND, F. R. Dec. 16, 1947, No. 33168. Convention date, Dec. 19, 1946. [Class 75(i)] A vapour burner of the kind in which liquid fuel passes from a tank 1 through a pipe 4 passing through a preheater 10 to a vapourizing tube 5 leading to a chamber 2 where the vapour is superheated and passed to a burner nipple 3, the chamber 2 being connected by tubes 8, 9 to the upper. end of the tube 1 so that a vapour pressure the same as that tending to retard the flow of fuel through the tube 5 is applied to the surface of the fuel in the tank 1, is characterized by the feature that when the burner apparatus is adjusted for normal operation a condition of vacuum is set up in the liquid fuel tank, in the absence of vapour pressure at the burner, whereby the liquid fuel is unable to pass to the burner from said tank. The tube 8 extends near to the bottom of the chamber 2 so that, when the burner is started up by opening a fuel cock 7 in the pipe 4, fuel flows into the chamber 2 only to the level of the lower end of the tube 8 when a vacuum seal is established in the tank 1. The fuel thus supplied is vaporized by igniting volatile fuel placed in a depression 15 in the base of an air supply housing 12 and passes to the nipple 3 where it is ignited, and, the vacuum seal being then broken, the fuel supply through the pipes 4, 5 continues. A filter 19, a pressure regulator 16, and a flow limiting jet 18 are provided in the fuel supply line, and an expansion and cooling jet 17 connects the pipes 8, 9. The preheater 10 is in the form of a heat exchanger through which the hot vapour passes. The housing 12 is provided with air inlet holes 11a and is supported by a plate 20 on the front of a furnace or firebox. A shutter (not shown) may be provided to control the air flow through the inlets 11a and may be actuated from the control spindle of the cocks 7 to vary the air supply in proportion to the fuel supply.

Title: Electrical circuit for controlling the energization of an inductive load
IPC: H02M1/08
Filed: 1972-07-19
Abstract: 1335784 Switching inductive loads NATIONAL CASH REGISTER CO 19 July 1972 [2 Aug 1971] 33694/72 Heading H3T [Also in Division H2] Energy stored in an inductive load is transferred to storage means when the energizing supply is switched off and upon reconnecting the supply the stored energy switches on a gate controlled switch which connects the storage means to assist the energizing supply. Upon switching off the transistor 24, the energy in the inductor 12 of a stepping motor is transferred via diodes 20 and 28 to a capacitor 20. When transistor 26 is switched on again, current from the capacitor flows through the transistor to the gate of thyristor 40 and switches it on. The capacitor is thus connected in aiding relation to the supply and the inductor is rapidly re-energized. When the capacitor is discharged the thyristor becomes non-conductive and a holding current flows from the supply through diode 20. During long off periods the capacitor is maintained charged via resistor 36.

Patent GB-430007-A (GB)
Title: Improvements in the separation of ammonia and hydrogen sulphide from gases
IPC: C10K1/08
Filed: 1933-12-04
Abstract: In the removal of ammonia and hydrogen sulphide from gases such as coke oven gas, the ammonia is first removed by sulphuric acid, yielding ammonium sulphate, and after the hydrogen sulphide has been removed by a scrubbing process, the spent scrubbing agent is regenerated, and the hydrogen sulphide, sulphur dioxide, or sulphur so obtained converted to sulphuric acid for use in removing ammonia from further quantities of crude gas.  When separating the hydrogen sulphide by means of bog iron ore, iron oxide suspensions, or solutions of arsenic compounds, residual ammonia not removed by sulphuric acid is mainly converted to ammonium thiosulphate and thiocyanate during regeneration of the spent scrubbing agent by air, and these compounds are decomposed by an excess of sulphuric acid which is then used in the first step of the process.  Sulphur dioxide obtained in decomposing the compounds is added to that obtained by burning the sulphur resulting from regeneration of the scrubbing agent, and the sulphur dioxide catalytically oxidized to obtain sulphuric acid for absorbing the ammonia.  The waste gases containing residual sulphur dioxide, and the air used for oxidizing the spent scrubbing agent, containing residual ammonia are washed with water, and the ammonium sulphite solution decomposed with a part of the sulphuric acid, the sulphur dioxide formed being converted to sulphuric acid.  When the hydrogen sulphide is removed by means of solutions of strong organic bases, such as ethanolamine, or of salts having a basic action such as alkali metal salts of amino acids, which are regenerated by heating with recovery of hydrogen sulphide, the latter is burnt to sulphur dioxide which is catalytically oxidized.  The waste gases from this oxidation are washed with ammonia, which may be residual ammonia retained by the purified gas, to give ammonium sulphite, and the latter decomposed with a part of the sulphuric acid with formation of sulphur dioxide which is returned to the main body of gases to be oxidized.  By adding to the sulphuric acid used for absorbing the ammonia waste acids from the purification of benzene, or phosphoric or nitric acid, mixed fertilizers may be obtained instead of ammonium sulphate.ALSO:Mixed fertilizers are obtained by absorbing ammonia from gases such as coke oven gas by means of sulphuric acid to which has been added waste acids from the purification of benzene, or nitric or phosphoric acid.
