Patent GB-651592-A (GB)
Abstract: 651,592. Ignition systems; sparking plugs. SMITSVONK, N. V. Aug. 6, 1948, No. 20855. Convention date, Aug. 2, 1943. [Class 7(iv)] [Also in Group XI] In an electrical igniting apparatus particularly for igniting a liquid-fuel burner and comprising a creeping-spark spark plug, a condenser system and an electrical contact device, the spark plug is provided at its active end with a chamber or recess 24, Fig. 3, to receive an accumulation of liquid fuel, and the electrical system produces two sparks in succession on the active surface of the spark plug, the first spark atomizing and the subsequent spark igniting the said liquid fuel. The active surface of the. spark plug consists in the outer end surface of an annular insulating or semi-conductive member 23 interposed between the electrodes 21, 22. The recess 24 may collect fuel from the discharge from the burner jet or may be supplied independently, and the shape of the recess 24, which controls the form of the cloud of atomized fuel produced by the first spark may, alternatively, be that of a hyperboloid, a sphere, truncated cone, or an inverted truncated cone. The electrical system comprises a storage condenser 13, Fig. 1, which is charged through a rectifier 15 from an induction coil 16, 14, energized on closing a push button switch 1 by a battery 2 which at the same time energizes the coil 3 of a relay 3, 4. The latter has a contact arm 8 which is moved out of engagement with a contact 9 into engagement with a contact 10, whereby the storage condenser 13 charges a smaller condenser 11 through the spark plug 12 thus producing the first spark. The arm 8 then engages an earthed contact 9<SP>1</SP> to discharge the condenser 11 through the spark plug 12 thus producing the second spark. The interval between the two sparks may be controlled by regulating the speed of the arm 8 by adjustment of an escape hole 7 in a cylinder 6 in which moves a piston 5 connected with the armature 4 of the relay 3, 4. An alternative circuit is described in which the single condenser 11 is replaced by a plurality of condensers which are discharged in succession by the relay 3, 4, and which may have different capacities so that sparks of different intensities are produced.

Title: Coal liquefaction
IPC: C10G1/00
Filed: 1980-11-11
Abstract: Coal liquefaction by solvent extraction at 1 with a proton-donating solvent (e.g. hydrogenated anthracene oil) results in an extract which is contaminated with mineral solids and unreacted coal solids which can poison catalysts used in subsequent processing. These solids are removed by treating the extracts at 2 under supercritical conditions with an organic vapour (e.g. toluene, hexane or crude coke benzol) or inorganic gas (e.g. carbon dioxide) having a critical temperature of greater then 31 DEG C and a critical pressure of less than 100 atmospheres so that the extract passes into the gaseous phase. By controlled expansion and cooling first to 100 to 350 DEG C and 25 to 75 atmospheres at 5 and then to 100 to 150 DEG C and 1 to 5 atmospheres at 7, first the coal liquid 11 and then the proton- donating solvent 13 may be separately recovered. A third expansion and cooling may recover the organic vapour or inorganic gas 12. The second and third recovered material may be recycled. <IMAGE>
