Filed: 1965-02-15
Abstract: 1,027,259. Ignition systems. ROTAX Ltd. Feb. 15, 1965, No. 6421/65. Heading FIB. A condenser discharge ignition system employing a control gap 20 includes means 25, 26 for reducing the voltage at which the control gap breaks down so that sparks of different energies can be obtained and means for reducing the rate of energy transfer through the transformer in the charging circuit when the voltage at which the control gap breaks down is reduced. As shown current flows from the source 9 through the winding 6 until the magnitude of the pull exerted on the arm 11 exceeds the opposing effect of the spring 13 opening the contacts 10, 14. In order to obtain lower energy sparks the switch 28 is left open so that the switch 26 is left closed. When the switch 28 is closed current flows in the winding 29 the effect of which is to assist the action of the spring 13. The current flowing in the winding 6 now has to rise to a greater value to overcome the increased opposing action.

Abstract: 1292812 Crystal separation process IMPERIAL CHEMICAL INDUSTRIES Ltd 26 Jan 1970 [10 Feb 1969] 6986/69 Heading B1G The separation of a crystallisable component from a solution thereof is carried out by a process in which crystals of the said crystalisable component are firstly produced by chilling of the solution (step 1), which crystals are separated from the mother liquor (step 2) and remelted to produce a second solution (step 3), chilling being carried out on this (step 4) to obtain a second crystal slurry, at least some of these crystals being separated from the mother liquor. These crystals are product and removed at 10. The liquor resulting is optionally divided into two streams, one of which is recycled to the second solution at 3, along with some crystals, and the other chilled (step 6) to produce further crystals and a liquor which is recycled to the first solution (at 1). The crystals (separated at 7) may be used for product or are recycled to either 3 or 4. The separators may be either filters or centrifuges, a centrifuge being preferably used at step 5. At steps 5 and 7 the crystals and mother liquor may be washed using, e.g. a C 4  or C 6  paraffin such as pentane, or paraxylene, the mother liquor and the melted crystals (after separation) being distilled to remove the wash liquor. The liquor 9 separated at the first separation may go to an isomerisation plant to be used as further feedstock.
