Patent GB-268547-A (GB)
Title: Improvements relating to the resolution of emulsions or suspensions containing tar or oil
IPC: C10G33/06
Filed: 1926-03-30
Abstract: 268,547. Robinson, H. W., and Parkes, D. W. March 30, 1926. Mineral and tar oils, purifying and recovering.- A finely divided mineral powder which is more easily wetted by water than by oil is added to an aqueous emulsion or suspension containing tar or oil, whereby a high proportion of the aqueous phase is agglomerated to a thick mass, and a high proportion of the other phase is separated out. For instance, air separated granite dust, slate dust, or powdered marble may be added to an emulsion heated, say to 60‹ C., and containing 30-35 per cent of water, when the oil separates out from the mixture; or previously used granite dust, revivified by drying, may be added to an emulsion containing more than 40 per cent of water in the cold, when the water first separates out and is removed, further emulsion or suspension being then added, and the whole being heated, say to 70‹ C., when the oil separates out. The emulsion is preferably rendered slightly acid before treatment, as by passing carbon-dioxide, sulphur-dioxide, or flue gases therethrough. Emulsions or suspensions containing different proportions of water may be blended to give mixtures having a suitable water content, say 30-35 per cent, for treatment. Granite dust, when first used, agglomerates only with the water, but used dust, revivified by drying, will agglomerate with the oil in the emulsion if the latter contains over 40 per cent of water. Examples of the various methods of treatment are given. The treatment of crude gas tars before distillation results in the removal of corrosive substances such as ammonium chloride and hydrochloric acid.

Title: Improvements in or relating to sprinkler type fire fighting installations
Inventor: TAYLOR JOHN NOEL
IPC: A62C35/60
Filed: 1963-10-03
Abstract: 1,083,457. Sprinkler system accelerator. MATHER & PLATT Ltd. Sept. 30, 1964 [Oct. 3, 1963], No. 8955/67. Divided out of 1,083,456. Heading A5A. A latch-operated main control valve 1 in a sprinkler system is operated by movement of a diaphragm 6 cooperating with the latch 4 by means of the plunger 5 The said diaphragm is contained in a chamber 13, one side of which is connected to the interior of the system via pipe 19. A float chamber 15 is connected through pipework 16 to a 3-way valve 17 (used for testing), to the "front" side 19 of the diaphragm and, through a restrictor (e.g. a porous plug 20) to an air bottle. In the bottom of the float chamber is a well 25, across which is stretched a diaphragm 26, on which rests a button 27 formed on the under surface of a float 28 pivotally secured to the chamber by the resilient strip 29. The well 25 is connected to the air bottle on the bottle side of the restrictor so that, in the steady state, there is no pressure differential across the diaphragm 26 and the float depresses it. The float 28 also carries a seating 31 which blocks a passage 32 between the float chamber 15 and the back side 33 of the latch-operating diaphragm 6. A rapid drop in pressure within the system (caused e.g. by operation of a sprinkler head) creates a pressure differential across the diaphragm 6, which lifts the float 28 and opens the passage 32, thus counteracting the installation pressure on the front side of diaphragm 6 and a spring 34 causes operation of the plunger 5, latch 4 and the main control valve. On the other hand, slow pressure variations within the system do not cause the system to operate, since the reference pressure in bottle 21 can also alter slowly. Similarly, slight leaks past valve 1 causes the float 28 to rise, thus opening the passage 32 to allow water to drain into chamber 33, whence it passes through a water drain valve 36 back to the main inlet, but more serious leaks cause the float 28 to rise sufficiently to operate latch 4 to release a seal 3 to allow water to pass into the alarm groove 7 and thence to an alarm system 11.
