Title: Encapsulated emulsions and processes for their preparation
IPC: A01N25/28
Filed: 1959-11-26
Abstract: Particles of a (primary) oil-in-hydrophilic liquid emulsion containing a thickening agent in the hydrophilic liquid phase are encapsulated by forming a secondary emulsion comprising the said primary emulsion dispersed in a coacervating solution comprising a coacervating agent and an aqueous dispersion of a linear macromolecular synthetic polymer and allowing a coacervate to form about the particles of primary emulsion and which may subsequently be hardened, plasticized and/or dried.  Suitable thickening agents are: acacia, tragacanth, methyl cellulose, carboxymethyl cellulose, magnesium aluminium silicate, polyglycols, glycerine and syrups. Suitable polymers are those whose structure comprises both lipophilic units and hydrophilic units, e.g. hydrolysed styrenemaleic anhydride copolymers and modifications thereof, those preferred being of the general formula [-R-R1-]n wherein R represents lipophilic units of which more than 70% are styrene residues and R1 represents lipophilic units of which more than 50% are maleic acid residues.  Other polymers mentioned are: styrene-maleic acid amide and methylvinyl ethermaleic acid copolymers, sulphonated polystyrenes and carbohydrate acetate phthalates.  The coacervating agent may be an electrolyte or a water-soluble liquid in which the coacervating polymer is less soluble than in water. Solubilizing agents, particularly polysaccharides, e.g. alginates, pectins, methyl cellulose and Irish moss derivates may be included in the polymer solutions.  Either or both phases of the primary emulsion may contain dissolved or dispersed materials which render the capsules of the invention useful as fertilizers, plant growth regulants, bactericides, pesticides, food additives, medicines and cosmetics. Specific examples relate to: (a) mineral oil-in-aqueous urea solution in styrene-maleic acid copolymer and (b) corn oil-in-aqueous rotenone dispersion in the same polymer.  Specification 751,600 is referred to.

Abstract: 1,176,306. Selective signalling. FRIDEN, Inc. 26 Aug., 1968 [2 Oct., 1967], No. 40704/68. Heading G4H. In a paper strip 22 printer each character to be printed is entering into a counter 66 which is then advanced to zero by clock pulses CM, CP produced by an inductively senses toothed index wheel 72 moving with a type wheel 12, and when a count of zero is reached, at which instant the desired character will be adjacent the paper strip, a control signal PH is applied to a print hammer 57, 48. Whenever all the stages of the counter are not in their zero state state an AND gate 98 produces a signal which inverted 106 and used to drive a motor 24 which rotates the type wheel 12 and advances the paper via a worm gear 26, 28 and a friction wheel 32. Whilst the motor is accelerating, having started from rest, the amplitude of the pulses produced by the index wheel 72 and also those produced by a reference projection 86 on it is too small for them to have any effect. Once running speed is attained, the next pulse IM produced by the reference projection sets a trigger 94 allowing subsequent clock-pulses CM, CP to advance the counter 66 to zero where upon printing occurs. Also, but for a delay element 108 power to the motor would, but the delay element 108 maintains the motor energized for a sufficient period after the counter 66 has reached zero for a further character to be entered therein. In this way, if a sequence of characters is to be printed the motor runs continuously until the sequence ends.

Abstract: 895,603. Determining qualities of materials. IMPERIAL CHEMICAL INDUSTRIES Ltd. Dec. 18, 1959 [Dec. 29, 1958], No. 41855/58. Class 37. In a gas detector discharge tube arrangement for gas chromatography having means for detecting and measuring the voltage across the tube, the tube electrodes are heated when it is desired to free them from contamination and the device has an inlet and an outlet for gas. To do this the electrodes are heated by a flame, R.F. current, electric heaters incorporated in the electrodes or preferably by a larger than normal voltage across the tube electrodes to increase the discharge current. The heating may be " when desired " or automatically at regular time intervals. Preferably two gas discharge tubes D1' D2 as in Specification 895,602 are in the anode circuits of two pentodes V1, V2 operated under constant current conditions as in Specification 895,604, a recording potentiometer RP measuring the difference in potential across tubes D1, D2 one of which has carrier gas passed therethrough and the other carrier gas plus gas or vapour to be detected. The tube pressures are 4 mm. Hg and they are operated in the " normal glow regions." For the positions of switches N, N shown, the circuit operates normally. These switches are actuated automatically on a time base so that when moved to positions EC the pentodes V1, V2 are shorted out. This increases the current through gas discharge tubes D1, D2 to clean the electrodes thereof.
