Abstract: 967,725. Mixing liquids in flow. BRITISH PETROLEUM CO. Ltd., DE HAVILLAND ENGINE CO. Ltd., and RINGSDORFFWERKE G.m.b.H. March 23, 1961 [April 11, 1960], No. 12787/60. Heading B1C. [Also in Division G3] In a fluid dispensing and blending system means are provided for dispensing either a specified volume of a selected blend or a volume of a specified blend having a specified monetary value. Two fluids, 1A, 1B, Fig. 2, to be blended, each pass via a metering device 2A, 2B, each of which, by means of photoelectrically sensed discs, produces a train of pulses representing the volume of fluid passing and a second train of pulses representing the value of the fluid passing. The two value representing pulse trains are shaped 13A, 15, counted 19 and displayed 21 as are the two volume representing pulse trains by similar devices 12A, 16, 20 and 22. The particular blend of the two fluids which is produced at an output 26 is determined by a pre-set balance unit 27 which so controls two mixing valves 23A, 23B that the ratio of the two volume representing trains of pulses is maintained at the pre-set constant value. Delivery of the blend to the output 26 is stopped by a valve 24A, 24B, when a signal is received by it from either a counter 31, which can be pre-set to a desired monetary value, or from a counter 33 which can be pre-set to a desired volume, a switch 36 determining which of these two counters is to be effective. An additional circuit, Prov. Fig. 3 (not shown), maintains the pre-set blend of the two fluids. Specifications 909,684, 909,685, 911,464, 967,724 and 967,726 are referred to.

Abstract: 568,754. Sodium percarbonate. SLATER, V. W., WOOD, W. S., and LAPORTE, Ltd., B. Aug. 9, 1943, No. 12830. [Class 1 (iii)] Sodium percarbonate is obtained by a cyclic process wherein hydrogen peroxide and sodium carbonate are added simultaneously or alternately in small quantities to the mother liquor from a previous operation. The reactants may be added in the proportions required by the formula 2Na2CO3.3H2O2 ; or sodium,carbonate in excess of that required by the formula may be maintained throughout the reaction. The solution may also contain a stabilizer, sodium silicate being preferable to magnesium sulphate or magnesium trisilicate for this purpose ; sodium metaphosphate to promote the formation of a granular precipitate ; and sodium chloride, sodium sulphate or other alkali metal salt in order to reduce the solubility of the sodium percarbonate. The process may be conducted at normal temperatures, e.g. 15 C., but the temperature may rise to 22 C. or 25 C. In the preferred embodiment, the sodium metaphosphate is added to 'the clear mother liquor from a previous batch and the sodium silicate is added pari passu with the reactants, although the first additions of the reactants may be made without sodium silicate. The additions of the reactants may be made at five-minute intervals. A make-up quantity of sodium chloride is added to the batch before the sodium perborate is filtered by means of a centrifuge.
