Patent GB-1250695-A (GB)
IPC: B65D63/00
Filed: 1969-12-15
Abstract: 1,250,695. Precipitation. SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ N.V. 15 Dec., 1969 [16 Dec., 1968], No. 60938/69. Heading G1X. [Also in Divisions C4 and C5] In the separation of hydrocarbon mixtures by treatment with an aqueous solution of an adduct forming agent, e.g. urea, thiourea or antimony trichloride, followed by separation of the adduct from the remainder of the mixture, the pressure and temperature in the adduct forming-zone are such that the solution of adduct-forming agent boils and is concentrated by evaporation during the treatment. The evaporation can be continued until a suspension of adduct containing grains have been formed or until the solution has lost practically all of its water, in which case fire particles containing the adduct are formed. The solution of adduct forming agent and the hydrocarbon mixture can be introduced into the zone by squirting or atomising either separately or in admixture. An aqueous solution of urea 3 is mixed with a hydrocarbon feed 1 and atomised into the zone 2 which is maintained at 30-70C. A diluent 4, e.g. light gas oil or kerosine boiling from 150-250C, can be added as such or admixed with the solution of adduct-forming agent and/or the feed 1. The solid adduct is separated at 15 from the stream 14, a liquid 25 and the adduct 17. The adduct is decomposed at 19, using hot water and/or steam from line 20, to form a mixture which is separated at 23 into an oil stream 24 and an aqueous solution of urea which is recycled to the zone 2. The water vapour from zone 5 is either condensed at 6 and the condensate passed to line 20 to decompose the adduct at 19 or compressed at 26 and passed into zone 19. The stream 25 can be separated to recover the diluent for recycle to zone 2 and the raffinate which can in part be recycled to the zone 2.

Abstract: 1,252,470. Photo-electric colorimeters. NUCLEAR-CHICAGO CORP. Sept. 26, 1969 [Oct. 1, 1968], No.47411/69. Headings G1A and G1J. [Also in Division G3] A photo-electric colorimeter comprises an unscaled meter to which can be added one of a plurality of inter-changeable scales or dials, which when placed in position causes switching into circuit of a respective photo-cell, responsive to light of a particular wavelength range, so that the colorimeter may be used to investigate a liquid sample as regards the particular constituent for which the dial is designed. The colorimeter comprises a housing 20 with controls 14-18, a temperature controlled rack 32, 22 for samples awaiting test and a test well 31, 21. The temperature control circuit is illustrated in Fig. 10 (not shown) as is a transistorized timer circuit which lights an alarm lamp after a first period and sounds a loudspeaker after a second period warning the operator when the sample incubation period has expired. A typical scale or dial 40, has notches (43-46) Fig. 2 (not shown) in a unique combination arranged to actuate certain of members 73-76 on insertion and so switch into circuit a particular photo-cell 65-68. The dial comprises a transparent plate carrying the scale and is held by springs engaging notches 47. Alternatively to notches, conductive elements in particular configurations on the plate can switch in the photo-cells. In an alternative apparatus, a number of dial members may be inter-connected to form a continuous belt which is fed through an adapted slot. Insertion of a test vial 80 brings it between the ends of fibre optic light guides 55-58 and aligned photo-cells 65-68, individually responsive to particular wavelength ranges. The light guides have numbers of fibres appropriate to their respective photo-cells and are fed by a common lamp (51) via lens (52) and infrared absorbing filter (54), Fig. 8 (not shown). Supply circuitry for lamp and photo-cells is given in Fig. 10 (not shown). Calibration of each scale or dial is with a known sample by a potentiometer (16) so as to locate the indicator pointer 29 on a calibration mark usually centrally located on the scale. The test sample may be blood and a variety of tests for particular blood constituents are exemplified, together with details of the required wavelength response of the photo-cells for particular components.

Abstract: 1,253,054. Sealing ceramics. B.T.R. INDUSTRIES Ltd. 5 Sept., 1969 [5 Sept., 1968], No. 42289/68. Heading B3V. [Also in Division C1] High temperature resistant fibres, e.g. glass or ceramic fibres, of softening temperature 300- 1200‹ C., are formed into a reticulated material by reacting a binder disposed on the fibre surface with a reagent so as to release sufficient thermal energy to fuse the fibres together at the points where they are bound by the binder. The binder may be applied to the fibres before, after or simultaneously with the reagent, which may be such that heating is required before the reaction occurs. The binder may be inorganic or organic, e.g. polyvinyl acetate, starch oil size, polyvinyl alcohol, polyesters, phenol-formaldehyde resins, aqueous melamine colloids, and natural glues, resins and tannins. The reagent may be one which releases oxygen, e.g. inorganic nitrates (KNO 3 ), peroxides, chlorates, bromates, perchlorates or permanganates, or an aromatic or alkyl-aryl peroxide (benzoyl and dicumyl peroxides).

In a spark spectrography apparatus a turn-table 2 can be both rotated about its own axis and moved laterally relative to a vertical electrode 1. A motor (14b), Fig. 4 (not shown) in a casing 14 rotates a pinion 20 and thereby rotates the turntable 2 through the action of a ring gear 22 and a second pinion 18. To achieve lateral movement an electromagnetic clutch 26 is operated to cause the ring gear 22 to drive a pinion 30 via a shaft 28. The pinion 30 is fixed relative to the carriage 8 and co-operates with a rack 32 which is fixed relative to the ground so that rotation of pinion 30 causes it and the whole carriage to move. The motor (14b) drives a dynamo (14c) Fig. 4 (not shown) whose output is connected to a phase-shift device (54) and the difference between the output of this device and the voltage taken from a fixed potentiometer 48 as the contact 46 is moved by the carriage 8 is used to provide the original motor drive. A point under the electrode 1 thus sweeps out a spiral and equal areas of the turn-table surface spend equal times under the electrode.
