Title: Improvements relating to the production of sensitive photographic emulsions
IPC: G03C1/053
Filed: 1939-02-14
Abstract: 527,283. Photographic emulsions. KODAK, Ltd. (Eastman Kodak Co.). Feb. 14, 1939, Nos. 4652/40 and 4757/40. Divided out of and addition to 525,085, [Group IV]. [Class 98 (ii)] The binder of a photographic emulsion is an aqueous solution of polyvinyl alcohol or a partially hydrolyzed polyvinyl ester, such as the acetate (hydrolyzed to water-solubility) containing a sufficient quantity of a gelling agent, such as is specified in Specification 525,085, to render the solution gelable. The emulsion is preferably a silver halide emulsion and may be washed or unwashed, and may be applied to a support of glass, film base or paper. Gelling agents referred to are the sodium and other water-soluble salts of the hydroxybenzol ketones and of amides such as 3-hydroxy-2- naphthoylanilide, di-(3-hydroxy-2-naphthoyl)- benzidide, and #-naphthyl-salicylamide, phenols such as resorcinol and hydroquinone, and pyrogallol and gallic acid. Coloured emulsions are prepared using gelling agents which are dyes or otherwise capable of colouring the gel. The gelling agent may absorb ultra-violet light. Gelling agents causing fog may be used in emulsions for use in reversal processes. Gelling agents having a dispersing action such as the hydrochlorides of 5-amino-1-naphthol and 1-amino-4-naphthol, Congo Red, Diamine Red, Congo Corinth and Azoorseillin may be used. Additional dispersing agents such as amines, substituted amines, or other organic nitrogenous compounds may be used. A colour sensitizer may be added to the emulsion or a gelling agent having a sensitizing effect may be used. Gelatine or other binders may be added. The emulsion is preferably made by precipitating the silver halide or other light-sensitive material in a solution of the polyvinyl compound before addition of the gelling agent, and adding the latter at a later stage either in aqueous solution or in aqueous solution of polyvinyl alcohol or partially hydrolyzed ester. Several examples of the preparation of silver halide emulsions including the use of resorcinol and #-naphthyl-salicylanide as gelling agents are described.

Title: Improvements in dynamo-electric generators
IPC: H02K23/22
Filed: 1941-04-15
Abstract: 597,149. Generators; self-contained systems. GUILBERT, A. V. E. C. April 15, 1941, No. 4918. Convention date, April 12, 1940. [Classes 35 and 38 (iv)] A three-brush D.C. generator has non- distributive compensating windings disposed symmetrically with respect to the axis of each pole and traversed by the current in the external circuit, and circuit arrangements are provided whereby the current in the compensating windings is reversed when the direction of rotation of the generator is reversed. The polepiece may be divided into two portions by an intermediate slot 3, Fig 3, round which are wound separate coils 4, 5. In one method, only that one of the coils 4, 5 is used which is over the leading tip of the pole-face. In another, the coil over the trailing tip is reversed, if desired with a shunting resistance, so as to strengthen flux of the leading tip and weaken that of the trailing tip. In another form, in addition to the main exciting winding 6, a series winding 8 surrounds the whole pole. On reversal, the connections of coil 8 remain unaltered. In a modification, Fig. 4, the pole is H-shaped and a single coil 10 on the cross-bar replaces coils 4, 5. In all cases, the current in coils 4, 5, 10 is reversed by a suitable switch, Fig. 5 (not shown), when the generator is reversed. To avoid over-voltage if the floating battery fails, relay 18, Fig. 7, closes the exciting circuit only if actuated by battery 12 ; the voltage of the battery becomes excessive, a further relay 20 short-circuits relay 18 and removes the excitation. Two such machines may be run in parallel by making the resistances of the compensating windings inversely proportional to the powers of their respective machines, thus securing that each delivers a current proportional to its load, Fig. 8 (not shown). Specification 425,911 is referred to.

Abstract: 952,948. Counting apparatus. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Feb. 7, 1963 [Feb. 12, 1962], No. 5287/62. Heading G4D. If radio-activity from a sample is high, a predetermined count is reached quickly to operate an alarm. If the radio-activity is low the counter is reset after a predetermined time. If, however, the activity is at an intermediate level and errors may arise due to random sampling the predetermined time period is extended, achievement of said predetermined count then operating the alarm after a longer delay. A paper tape 1 collects dust samples in consecutive five-minute periods and is exposed to detector 2 for like periods. Pulses from plutonium are passed directly to unit counter 3 but those from uranium are divided by 30 before application to the counter. If a count of 37 is reached within a five-minute period then an alarm 7 operates, i.e. dangerous radio-activity is detected within ten minutes. If a count of less than 9 is reached the counter is reset after five minutes and the next sample is tested. If a count of 9 is reachedbi-stable element 10 inhibits resetting and the counting period is extended to twenty minutes. If the alarm has not operated in this time divider 12 resets bistable element 10 to allow resetting of the counter.

Title: Improvements in and relating to coating processes
IPC: B29C65/48
Filed: 1964-02-07
Abstract: Layers of thermoplastic polymeric materials are bonded together by surface-activating at least one layer, applying a layer of the other material to the activated surface, and irradiating the layers with ultraviolet light through the more U.V.-transparent layer.  The second layer may be applied by coating, as by extrusion or dipping in a solution or emulsion.  One layer may be a polyolefin film and this, whether or not the activated layer, is in general that through which the U.V. irradiation is effected. The other layer may be a film of (a) vinylidene chloride copolymerized with a small proportion of other monomer such as acrylonitrile, vinyl chloride, alkyl methacrylate or alkyl acrylate or mixtures thereof (many other examples are given in the Specification), or (b) a polyester such as polyethylene terephthalate, or other reaction product of a glycol with a dibasic acid such as adipic, sebacic, isophthalic, azelaic, maleic, bibenzoic, hexahydroterephthalic, or 1,5-, 2,6- or 2,7-naphthalene dicarboxylic acids.  Surface activation is preferably effected by electrical discharge but may be by flaming or treatment with concentrated or fuming sulphuric acid, sulphur trioxide, hot sodium hydroxide or with gaseous borontrifluoride, aluminium chloride or titanium tetrachloride, or a liquid co-ordinated complex thereof. Films used may be oriented, and the products embodying polyolefins may be used for making heat-sealable and heat-shrinkable bags and wrappers, particularly for foodstuffs and, in the case of polythene-polyethylene terephthalate products, for "boil-in-bag" applications such as heat-sterilizable hermetically sealed packages of pharmaceuticals. Examples refer to (a) a film of a 75/25 blend of low density/high density polythene activated by electric discharge and coated by dipping with an aqueous dispersion of a copolymer of vinylidene chloride/methyl acrylate/itaconic acid in weight ratio 92,5 : 7,5 : 1, the product being U.V. irradiated through the polythene; (b) a biaxially oriented, heat-set film of polyethylene terephthalate coated with an aqueous dispersion of a 94 : 6 : 1 copolymer of vinylidene chloride/acrylonitrile/itaconic acid and activated by electric discharge on its coated surface, the coated film being subsequently melt-extrusion coated on the coated surface with polythene, the product thereafter being irradiated with U.V. through the polythene.

Title: Improvements in high dielectric constant ceramic cavity resonators
IPC: H01P7/10
Filed: 1954-02-25
Abstract: 752,467. Cavity resonators. ERIE RESISTOR CORPORATION. Feb. 25, 1954 [March 20, 1953; Nov. 13, 1953], No. 5559/54. Class 40 (8). A cavity resonator comprises a body of high dielectric-constant (about 1000 or more) ceramic material, e.g. barium titanate having an exciting loop or electrode metallized upon its surface. The disc-shaped titanate body 1 of Fig. 1 has holes 5, 6 whose metallized coatings are joined by a short metallized strip on the underside of the body 1. These coatings form an inductive loop whose magnetic field is directed circumferentially around the body 1 and between metallic coatings 2 on either side of the disc. The exciting loop in the resonator 1 of Fig. 3 consists of an arcuate strip of silver 21. The resonator 1 in this embodiment is uncoated, the discontinuity occurring at the boundary of the body due to its high dielectric constant being relied upon to confine the electromagnetic flux within the body. The loop 28 of the resonator of Fig. 5 extends across two sides of the dielectric body and is insulated from the metallized portions 24, 25 by unmetallized strips 26, 27. The metallic coatings 24, 25 extend over both sides of the body. A disc-shaped resonator may be excited electrostatically by means of an electrode situated on the centre of one face (Fig. 8, not shown). Alternatively the electrode may be formed by coating a central cylindrical recess 34, Fig. 9, in one face of the body. An insulated metallic boundary coating 38 may be applied to the body. The resonator of Fig. 11 is in the form of an annulus 40 excited by inductive loops 45, 46. A central cylindrical section 39 is made of a material whose Curie point is below normal operating temperature, e.g. a mixture of barium and strontium titanates. Application of a control voltage to electrodes 41, 42 enables the frequency of the resonator to be varied. The cylindrical resonator of Fig. 12 may be excited by an inductive loop 50 or by an electrode (not shown) coated on to the bottom of an arcuate slot in the curved side of the cylinder.
