Title: Encapsulated emulsions and processes for their preparation
IPC: B01J13/10
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 medium comprising an aqueous dispersion of at least two coacervating polymers, at least one of which is a hydrophilic colloid and at least one of which is a linear macromolecular synthetic polymer and causing the polymers to coacervate and thus coat the dispersed primary emulsion particles by altering the pH or by dilution with water.  Suitable thickening agents are: acacia, tragacanth, methyl- and carboxymethyl-cellulose, magnesium aluminium silicate, polyglycols, glycerin and syrups.  As hydrophilic colloids there are mentioned gelable and nongelable hydrophilic colloids e.g. gelatine, agar, albumen, alginates, deacetylated chitin, acacia, starch and fibrinogen.  Suitable polymers are those whose structure comprises both lipophilic and hydrophilic units, e.g. styrene-maleic acid amide and methyl-vinyl ether-maleic acid copolymers, polymethacrylic acid, carbohydrate acetate phthalates and (preferably) hydrolysed styrene-maleic anhydride copolymers and modifications thereof, in particular those of general formula [-R-R1-]n, wherein R represents lipophilic polymer units of which more than 70% are styrene residues and R1 represents hydrophilic units of which more than 50% are maleic acid residues. Solubilizing agents may be added to increase the concentration of polymer, e.g. solvents and polysaccharides, e.g. alginates, pectins, methyl- and carboxymethyl-cellulose and Irish moss derivatives. Either or both phases of the primary emulsion may contain dissolved or suspended "active" ingredients which render the product of the invention useful as sustained release fertilizers, plant growth regulants, bactericides, and pesticides, as food additives, cosmetic ingredients and medicines.  Specific examples include: (a) mineral oil-in-caffeine aqueous suspension in gelatine and styrene-maleic acid copolymer, and (b) corn oil-in-aqueous rotenone suspension in fibrinogen and cellulose acetate phthalate.  Specification 751,600 is referred to.

Title: Stable dispersions of high molecular weight elastomeric substances
IPC: C08L83/04
Filed: 1957-12-31
Abstract: Aqueous dispersions of high molecular weight elastomers are made by mixing the elastomer with 3-3%, based on the weight of elastomer, of a copolymer formed from 1 mol. of a halfester of an alpha-beta ethylenically unsaturated dicarboxylic acid and a monohydric alcohol having at least 8 carbon atoms, e.g. a halfester of maleic or fumaric acid with decylol, dodecylol, octadecylol or a condensation product of dodecylphenol with at least 1 mol. of alkylene oxide, with 1-2 mols. of a monomeric monovinyl aromatic compound, e.g. styrene or styrene substituted in the aromatic nucleus by methyl, ethyl, isopropyl or butyl, an organic vinyl ester, e.g. vinyl acetate, vinyl propionate or vinyl benzoate, an ester of acrylic or methacrylic acid with an aliphatic monohydric alcohol having 4-20 carbon atoms or a conjugated diolefine having 4-6 carbon atoms, and then dispersing the mixture in water.

Title: Atomic frequency standard
IPC: H01S1/00
Filed: 1965-09-24
Abstract: 1,090,109. Molecular beams. VARIAN ASSOCIATES. Sept. 24, 1965 [Sept. 28, 1964], No. 40817/65. Heading G6P. In a caesium beam frequency standard, of the type described in Specifications 1,041,576 and 1,067,328 the vapour atoms are passed from the oven through a collimator. The latter is formed of a ring of short tubes, which are inclined towards the beam longitudinal axis and through which the atoms pass into the gap of the first state-selector magnet. The length and diameter of each tube is less than the mean free path of the caesium atoms. A " flop-in " system is described which incorporates a small-area detector which ionizes the atoms and directs them, first into a mass spectrometer and then into an electron multiplier. The output signal from the latter is fed into the beam feedback control loop. Thallium and rubidium may be used in place of caesium.

Title: Improvements in or relating to telecommunications exchange systems
IPC: H04M15/04
Filed: 1965-09-27
Abstract: 1,100,174. Automatic exchange systems. SIEMENS A.G. 27 Sept., 1965 [25 Sept., 1964], No. 40952/65. Heading H4K. At, or by ringing back at the end of a call, either invariably or on demand, the subscriber who originated the call is supplied by the exchange equipment with a record of the charge made for the call or of the total charge standing in his account. The facility, described schematically, is provided by a system where a central metering store records, in storage sections devoted to each subscriber, the charge accumulated for a call or the total accumulated for all calls, or both. The store may be a magnetic drum or a cyclically scanned magnetic core array. The demand for call charge data may, for privileged subscribers who receive the service for all calls, be generated automatically at the end of every call. Otherwise the demand is made by the subscriber by keying an earth pulse to his line, or by dialling his own identity where the exchange has no means of furnishing the identity itself. The demanding subscriber's identity is set up in a store at the exchange for comparison with the cyclically presented identities of the subscribers' meter stores. When a match is found the meter store is read out and may or may not be erased. The wanted meter total is decoded to a form suitable for transmission to the subscriber and may be decoded into a spoken announcement of the call charge. Each subscriber may have a printer to record the data. As each total is sent out to a subscriber it may be recorded and dated in punched tape at the exchange. Where a number of demands for call charges are being processed together the subscribers can make their demand and hang up, the exchange being provided with equipment to call the subscribers back when the data is available. The identities of subscribers wanting call charge information are set up in a group of registers allocated to each demand as it occurs, or the identities may be set up in registers provided in link circuits to which the subscribers are connected on calling the exchange.

The foamable mix and cellular bodies are preferably of the same composition, e.g. polyurethane. The or each cellular body, which may also be polystyrene, may have ridges &c. acting to space it from the mould wall. Reinforcement, e.g. glass fibre sheets or wire mesh, may be inserted in the space between the body and mould wall.

Patent GB-898406-A (GB)
Title: Process for the production of diisocyanates
IPC: C08L75/02
Filed: 1959-12-15
Abstract: In a process for the production of organic diisocyanates, polyureas are exposed at elevated temperature to the action of phosgene.  The polyureas used in the process are all compounds which contain the grouping -R-NH-CO-NH-R-NH-CO-NH-R several times, in which the radicals R can be the same or different hydrocarbon radicals which are unsubstituted or substituted by unreactive groups, e.g. alkyl groups, or halogen atoms.  If radicals in the polyurea are different mixtures of diisocyanates are obtained as products.  Polyureas specified for use as starting materials include 2,4- and 2,6-toluylene polyureas, m- and p-phenylene polyureas and a mixed polyurea in which one of the groups R is the 2,4-toluylene radical and the other is the 2,4-chlorophenylene or 1,6-hexa-methylene radical. The reaction may be carried out in a fluidised bed, e.g. of sea sand, inert gases, e.g. nitrogen or hydrogen being supplied together with phosgene to the bed if necessary.  The phosgene may be recirculated after separating out hydrogen chloride and the diisocyanate may be washed out of the gas stream by an inert organic solvent and isolated.  In another form of the process the polyurea may be finely ground and suspended in an inert organic liquid before treatment with the phosgene.  Organic liquids mentioned include aromatic or naphthenic hydrocarbons and chlorination products thereof.  Diphenyls and polyphenyls which boil above the boiling point of the diisocyanate are particularly suitable.  In examples: 2,4- and 2,6-toluylene diisocyanate and 1,4-phenylene diisocyanate are prepared from the corresponding polyureas using a fluidised bed of sea sand in a cyclone (1) and 2,4-toluylene diisocyanate is obtained by phosgenating a suspension 2,4-toluylene polyurea in chlorinated polyphenol after a brief initial treatment with hydrogen chloride (2) an apparatus for carrying out the process with a fluidized bed of sea sand is described with reference to a figure (not shown).
