Title: Improvements in and relating to the manufacture of photographic light-sensitive elements
IPC: G03C1/10
Filed: 1939-03-09
Abstract: 529,033. Photographic composite coloursensitive materials. KODAK, Ltd. (Eastman Kodak Co.). March 9, 1939, No. 7640. [Class 98 (ii)] Diffusion of a colour sensitizer from one light sensitive emulsion to another coated on the same side of a support is prevented or retarded either (1) by adding to the second-mentioned emulsion, or to an interlayer between the two emulsions, a soluble salt e.g. of an alkali metal, which is inert photographically and towards the light sensitive silver salt, and which forms a difficultly-soluble salt of the sensitizing dye, but does not form a very difficultly-soluble or undissociated salt with silver ; or (2) when the second-mentioned emulsion is not specially colour-sensitized, by adding to this emulsion a dye of a sensitizing class so chosen that it does not substantially alter the colour sensitivity of the emulsion. The emulsion may be of gelatino-silver halide, in superimposed layers or admixed in one layer. The salt used according to method (1) may be an alkali salt of one of the highest oxyacids of the halogens, e.g. a perchlorate or periodate. For silver bromide or bromiodide emulsions, the dye used according to method (2) may be one which sensitizes silver chloride emulsions for blue and violet, and examples are given in which the green-sensitizing dye 2 : 21-diethyl-3 : 4- benzthia - 2<SP>1</SP> - cyanine iodine is prevented from wandering into a neighbouring not specially colour-sensitized emulsion by dyeing this emulsion with 2 : 2<SP>1</SP>- diethyl : 5 : 6 : 5<SP>1</SP> ; 61- dibenzthiacyanine iodide, or 2 : 21-diethyl-3 : 4 : 3<SP>1</SP> : 4<SP>1</SP>-dibenzthiacyanine iodide, or 5-(1-methyl- 2-# naphthoxazylidene)-3-ethylrhodanine, or 1- (#-(1-piperidyl) - vinyl) - benzthiazole ethiodide.

Filed: 1968-02-16
Abstract: 1,145,427. Dewaxing hydrocarbon oils. SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ N.V. 16 Feb., 1968, No. 7705/68. Heading C5E. Hydrocarbon oils are dewaxed by precipitating the wax in the presence of a polyalkylacrylate of which the average number of carbon atoms in the alkyl side chains is at least 14, followed by separation. The oil may be a lubricating oil such as a residual oil or a waxy raffinate. The precipitation of the wax may be effected by cooling in the presence of a dewaxing solvent, such as a MEK/toluene mixture. Preferably, the polymer is added to the hydrocarbon oil as a solution in the dewaxing solvent. In the examples homopolymers of the following are used: n-hexadecyl acrylate, n-octadecyl acry. late and n-eicosyl acrylate.

Title: Improvements in or relating to the rinsing of bottles, jars or the like vessels
IPC: B08B9/28
Filed: 1938-03-12
Abstract: 507,109. Bottle - washing machines. HILL ENGINEERING CO. (HULL), Ltd., T., and HARRISON, N. C. March 12, 1938, No. 7706. [Class 138 (i)] An apparatus for washing bottles or jars, particularly such as have narrow necks, comprises a single lever, operation of which operates both a pump for the supply of compressed air, and a valve which permits the injection into the bottle first of cleansing liquid and then of compressed air to blow out the liquid. A thin nozzle 28 'for insertion into the bottle neck is carried by a hollow stem 12 connected to a source of liquid under pressure. The nozzle and stem can be interconnected by a passage 27 in a rotary valve member 18 carried by a spindle 14 to which a lever 16 is fixed. The lever is pivoted at 29 to a pump cylinder 30 movable over a piston 31. When the lever 16 is pressed down, liquid passes into the bottle through the nozzle, and air is drawn into the cylinder. When the lever is raised, the supply of liquid is cut off, and air from the cylinder is forced to the nozzle through a pipe 36 and a port 38 in the valve member. A sleeve 39 positions the bottle neck and discharges to a drainage tray 40. The lever 16 may operate also a second pump for supplying liquid to the nozzle, or may operate a single cylinder with two pistons.

Abstract: A continuos process for steam reforming hydrocarbons comprises reacting lower hydrocarbon mixtures of mainly C3 and/or C4 hydrocarbons with steam in a proportion of from 2 to 4 steam molecules per atom of carbon at a temperature of from 400 DEG  to 950 DEG  C. in the presence of a supported nickel catalyst comprising 5 to 50% by weight Ni (calculated as NiO), a refractory oxide material, and an alkali metal compound calculated as K2O of at least 0.5% by weight.  The nickel and the refractory are calculated on the sum of the weights of these components after calcination at 900 DEG  C., and the K2O preferably amounts to 1 to 7% by weight, calculated as above. The NiO preferably amounts to 12 to 31% by weight, and the refractory oxide may be one or a mixture of the oxides of Mg, Ca, Sr, Ba, Al, Si (in combined form), Ti, Th, Mo, or Cr, preferably magnesia and alumina or china clay. Specific compositions of hydrocarbon feedstocks, which may or may not be liquid, are given, and pressures of 3 to 30 atmospheres gauge are mentioned, and space velocities, expressed as kgs./hour of carbon per cubic metre of bulk catalyst, range from 100 to 1000. Five specific examples, employing a catalyst prepared according to Specification 953,877, are described, the compositions of the product gases being given. Air may be introduced into the steam-reforming process to increase the density of the resulting gas.

Patent GB-384156-A (GB)
Title: Process for the manufacture of aliphatic halogenated alcohols
Filed: 1932-03-19
Abstract: Halogenated aliphatic alcohols are manufactured by causing halogenated aliphatic aldehydes containing no carbon double bonds to react with halogen magnesium alcoholates, in the absence of any solvent or diluent, or in the presence of a solvent containing no hydroxy groups, and decomposing the condensation products formed by means of water which advantageously contains some mineral acid. When using a solvent containing no hydroxyl groups, a certain amount of alcohol may also be present.  The halogen magnesium alcoholates are prepared by reacting upon a halogen magnesium alkyl compound with an alcohol.  Advantageously they are prepared in ethereal solution and employed without isolation.  Other suitable solvents are benzene, ligroin, and anisol.  The reaction is preferably performed at room temperature but sometimes heating is advantageous for the completion of the reaction.  Examples describe the production of: (1) tribromoethyl alcohol from tribromoacetaldehyde in ethereal solution by means of bromomagnesium ethylate (from ethyl magnesium bromide and ethyl alcohol); (2) trichloroethyl alcohol from trichloroacetaldehyde in ethereal solution by means of bromomagnesium isopropylate (from ethyl magnesium bromide and isopropyl alcohol): (3) tribromoethyl alcohol from tribromoacetaldehyde in ethereal solution by means of bromomagnesium isopropylate; (4) as in (3) but using the reaction product of ethylmagnesium bromide and hydrobenzoin in ethereal solution; (5) as in (3) but in the absence of any solvent; (6) b -dichloro-g -chlorobutyl alcohol from a -dichloro-b -chlorobutyric aldehyde in solution in benzene, ether or anisol, by means of bromomagnesium n-butylate (from propyl magnesium bromide and butyl alcohol); (7) dibromoethyl alcohol from dibromoacetaldehyde in ethereal solution by means of bromomagnesium isopropylate; chloroethyl alcohol similarly from chloroacetaldehyde.

Title: Production of textile yarns and threads having incorporated therein rubber latex or analogous dispersions
Filed: 1934-03-16
Abstract: <PICT:0435395/IV/1> Doubled textile yarns impregnated with rubber or analogous dispersions are made by impregnating the individual yarns under differential pressure, clearing them from excess by means of a gas under pressure, and doubling whilst still moist.  The yarns are preferably impregnated whilst in cheese form.  The process produces yarns which are impregnated with rubber, but which have no surface coating.  The doubled yarn may be vulcanized, but mere drying may be sufficient.  The apparatus described in Specification 408,931 may be employed for the impregnation, or the simplified form shown.  The cheeses x on perforated metal holders are placed round a perforated pipe 3 in a chamber 1.  Rubber latex from the vessel 14 is forced by compressed air from the pipes 15, 18, 21 into the vessel 1, through the cheeses, via the pipe 3 to vessel 10.  The latex is then forced back again through the cheeses into vessel 14.  This may be repeated. Compressed air is then passed via the pipe 16, through the cheeses to clear them from excess latex.  The cheeses are then removed, and the yarn doubled whilst still moist.
