Abstract: The invention comprises water-insoluble, ionizable adducts of a mercuric salt of a cation exchange resin which is a sulphonated polymer of styrene cross-linked with divinyl benzene, an olefinic compound and a saturated alcohol of 1-4 carbon atoms and ketonic oxidation products made by oxidizing a C8- 25 aliphatic olefinic compound with ionizable mercuric mercury in the presence of a C1- 4 aliphatic alcohol and at least a trace of water, the reaction being effected in the presence of a sulphonated vinyl-aryl type of cation-exchange resin having a pore size sufficient to accommodate a molecule of the olefinic compound, and the oxidation product being extracted by means of an organic solvent. Specified olefinic compounds include straight and branched chain olefinic hydrocarbons, unsaturated alcohols, unsaturated acids and esters thereof.  The mercury is preferably in the form of a water-soluble salt of an organic or inorganic acid.  A catalyst, e.g. an acid, base or peroxy compound, may be present.  The preferred solvent for elution of the oxidation products is the alcohol used in the first step, but other solvents, e.g. ether, acetone, petroleum fractions, aromatic hydrocarbons and chlorinated hydrocarbons, may be used.  The examples relate to the preparation of ketones, keto-esters and keto-alcohols.ALSO:A water-insoluble, ionizable adduct comprises a mercuric salt of a cation exchange resin which is a sulphonated polymer of styrene cross-linked with divinyl benzene, an aliphatic olefinic compound and a C1- 4 saturated alcohol, the resin having a pore size large enough to accommodate the molecule of the olefinic compound.  Preferred resins are those containing 1-12% by weight of divinyl benzene based on styrene. Specified olefinic compounds are hydrocarbons, unsaturated alcohols, unsaturated acids and esters thereof.  The adducts may be made by first forming the mercuric salt of the resin, by treating the acid form with an aqueous solution of a mercuric salt, followed by treatment with the olefinic compound and the alcohol, either simultaneously or separately.  Examples relate to adducts of resins cross-linked with 2 and 4% of divinyl benzene and methyl oleate, methyl eleidate, methyl linoleate, octadecene and oleyl alcohol.

Title: Control circuit for a photographic camera
IPC: G03B7/083
Filed: 1975-01-23
Abstract: 1499032 Photographic cameras; exposure control EASTMAN KODAK CO 23 Jan 1975 [28 Jan 1974] 2972/75 Heading G2A An electronic circuit controlling the open time of the shutter of a photographic camera includes a trigger circuit which is responsive to a predetermined level of scene illumination and which modifies the controlled open time of the shutter only when the scene illumination is below the predetermined level. When a shutter is controlled by the light intensity, a maximum time of opening, e.g. 1/30 sec, may be set. If the level of light is low, underexposure may be so great that it cannot be compensated for by varying the processing. To obtain a compromise, the time of opening of the shutter, below a given light intensity, is caused to increase at a slower rate as the light diminishes, by the circuit shown. Operation of a shutter release member opens the shutter, closes switch 51, and shortly after opens switch 52, whereupon the condenser 38 begins to charge through the photoconductor 26. The greater the light intensity the lower the resistance of photo-conductor, the greater the current charging condenser 38, and the sooner the voltage across the condenser reaches a value at which the trigger circuit 34 (which may be a Schmidt trigger) operates. This causes the shutter mechanism 22 to close the shutter. Closure of switch 51 also causes current to flow in a photoconductor 54 and a resistance 53, connected at 52. The photo-conductor 54 is such that the lower the intensity of the light, the lower its resistance, and therefore the higher the voltage at 52. Point 52 is connected to a trigger circuit 50 in which the input stage is normally conducting, but is switched off when the input voltage falls below a given value, i.e. when the light value is too low. As the first stage switches off, the second stage switches on and lights a lamp 48 to indicate to the operator that the light level is such as to produce an underexposure. The voltage drop across lamp 48 causes a transistor 44 to conduct, and current flows in the emitter-collector path to condenser 38 to shorten the exposure at low light intensities, without limiting the exposure to a maximum. In a modification, photo-conductor 54 and transistor 44 are omitted, and light feedback is provided from lamp 48 to photoconductor 26 via a light conductor (60), Fig. 3, (not shown).
