Title: Encapsulated emulsions and processes for their preparation
IPC: B01J13/10
Filed: 1959-11-26
Abstract: Particles of a (primary) hydrophilic liquid-in-oil emulsion containing an anti-inversion agents in the oil phase are encapsulated by dispersing the said primary emulsion in an aqueous dispersion of a linear macromolecular synthetic polymer and a coacervating agent to form a secondary emulsion upon which the polymer is deposited and may subsequently be gelled and hardened. The primary emulsion may contain a conventional emulsifying and/or thickening agent, examples of the former being: esters of polyhydric alcohols, sorbitan and polyoxyethylene derivatives and of the latter (which may also be present in the coacervation solution); acacia, tragacanth, methyl- and carboxymethyl-cellulose, magnesium aluminium silicate, polyglycols, glycerine and syrups.  The anti-inversion agent may be any material capable of preventing the inversion of the primary emulsion on dispersion thereof in the coacervating solution, examples being: surface active agents (preferably non-ionic), oil thickening agents, e.g. waxes, fats, sterols and conventional oil-gelling or oil-thickening agents.  Suitable polymers are those of substantially linear structure which comprises both lipophilic units, e.g. styrene, substituted styrene, ether- or ester-substituted ethylene residues and hydrophilic units, e.g. maleic, acrylic, crotonic acid, maleic acid or acrylic acid amide residues, examples of such polymers being: hydrolysed styrene-maleic anhydride copolymers (preferred), styrene-maleic acid amide copolymers, sulphonated polystyrenes, methylvinyl ether-maleic acid copolymer and carbohydrate acetate phthalates. Solubilizing agents for such polymers, especially galactose polysaccharides such as Irish moss derivates may be used to obtain polymer solutions of suitable concentration.  As coacervating agents there are mentioned aqueous solutions of electrolytes, and water-soluble liquids in which the polymers are less soluble than in water and these may be added to the polymer solution before or after the formation of the secondary emulsion.  The primary emulsion may contain dissolved or suspended materials which render the capsules of the invention useful, e.g. as sustained release fertilizers, plant growth regulants, bactericides, pesticides, fungicides, food additives, vitamin preparations, cosmetic ingredients and pharmaceuticals.  Specific examples include an aqueous urea solution-in-corn oil emulsion coated with styrene - maleic acid copolymer which is useful as a slow-release fertilizer. Specification 751,600 is referred to.

A device for stimulating the activity of the heart comprises an input amplifier 13 for amplifying electrical signals derived from the activity of the heart, a pulse generator 14 for producing pulses at a standard rate, an output stage 15 for shaping the pulses so that they are suitable for heart stimulation and a regulating stage 16 for passing a stimulating pulse to the heart whenever the signal rate falls below the standard rate, such that the intensities of the stimulation pulses are automatically increased in steps to an adjustable maximum following a stimulation pulse that is too weak to stimulate the heart. The device has a selection switch controlling five circuits Sa to Se to permit four different kinds of operation wherein the device produces either continuous stimulating pulses, pulses responding to the input of an electrocardiogram through input 18, pulses responding to signals derived from blood pressure in the heart input through capacitor 21, and finally pulses responding to an external alarm system through input 27. The regulating stage 16 has a number of resistances controlled by a plurality of switching transistors, such that the resistances can be shunted in different combinations across a potentiometer 31 which controls the stimulation pulse. The resistance of the combination is increased in steps so that the stimulation pulse can be incrreased to a variable maximum at which a cut out circuit in stage 16 suspends the step increase action. Stage 16 has three inputs 37, 38 and 39, input 38 receives signals from input amplifier 13 and controls a gate so that no stimulation pulse is produced when a signal is received at input 38. The device also includes a stimulation pulse counter 17 and capacitors 20, 21 to differentiate the input signal to amplifier 13. The pulse rate of the generator 14 is controlled by a potentiometer 28 linked to a capacitor in the generator.
