Title: Manufacture of gelatine-reliefs for imbibition printing
IPC: G03C5/22
Filed: 1934-08-20
Abstract: 443,111. Photographic imbibition printing - surfaces. I. G. FARBENINDUSTRIE AKT.-GES., Frankfort-on-Main, Germany. Aug. 20, 1934, No. 23981. Convention date, Aug. 19, 1933. [Class 98 (ii)] Gelatin reliefs for producing imbibition prints on gelatin surfaces are produced by exposing a support carrying a gelatino-silverhalide emulsion layer having a thickness not greater than 1Á, which is coloured complementarily to its spectral sensitivity in order to obtain satisfactory gradation of the silver image, and contains a finely-dispersed solid substance consisting mainly of particles of a diameter not exceeding 1Á, and having no effect on the silver halide in order to obtain satisfactory reproduction of detail, developing the layer in a non-tanning developer to produce a silver image, and etching away the gelatin containing the silver image with hydrogen or other peroxide or ammonium persulphate. The solid substance may be white or colourless, in which case the emulsion is coloured with a soluble dyestuff. For example, the emulsion may contain barium sulphate, aluminium oxide, and silica and be coloured with naphthol yellow, acridine yellow G, or chrysophenine in the case of blue-sensitive emulsion, and with benzo-light red in the case of a green-sensitive emulsion. Or the solid substance may be a pigment which itself serves to colour the emulsion, and for this purpose there may be used sparingly soluble lakes of organic dyestuffs, and complex salts from basic triphenyl methane dyestuffs or xanthene dyestuffs with phosphoric, molybdic or tungstic acid (fanal lakes). For example a blue-sensitive emulsion may be coloured with Hansa-yellow or fanal lake of citroflavin, and a red-sensitive emulsion with indigo. For a panchromatic emulsion lamp-black may be used. Such coloured solid substances may be mixed with colourless solid substances. The pigments may be finely dispersed by comminution, or by the addition of wetting agents. The support may consist of celluloid, cellulose acetate, varnished " Cellophane " (Registered Trade Mark), polyvinyl chloride, or poly-acrylic acid ester.

Filed: 1966-05-27
Abstract: 1,134,345. Paving. MINNESOTA MINING & MFG. CO. 27 May, 1966, No. 23984/66. Heading E1G. [Also in Division C3] A polyurethane rubber paving surfacing comprises the hardened product of a blend of (1) 90 to 50% by volume of a liquid reaction mixture of (a) polymeric polyalkylene ether polyol, (b) an organic polyisocyanate and (c) a catalytic amount of an organic compound of a metal soluble in the reaction mixture and in the presence of which the mixture cured to a solid cross-linked polyurethane rubber under ambient conditions, the reaction mixture 'having sufficient trifunctional groups provided by one or more of the polyol, the polyisocyanate or a separate component to create a cross-linked product upon curing and (2) 10 to 50 vol % of resilient particles of a size from 0.15 to 2 cm. The paving surfacing may also contain up to 50% by weight of a finely divided particulate filler. Further resilient particles may be sprinkled on the surface before the binder has hardened or the paving may be topped by a coating of elastomer. In the preparation of the paving, a rigid substrate or foundation of e.g. asphalt or concrete is first laid and the polyurethane paving may be laid on this substrate either as a preformed strip or tile or as an in situ hardened paving. Figure 2 shows a method of laying the polyurethane surfacing in situ, wherein a truck bed' 20 is provided with a storage tank 22 labelled "Part A" containing a polyalkylene either polyol and e.g. filler catalyst and pigment and a storage tank 24 labelled "Part B" containing a liquid polyisocyanate. The resilient aggregate is carried in hopper 23 from which it is fed directly into the mixer 30 to be mixed with the parts A and B. Upon mixing the resulting paving material is deposited by means of chute 36 onto the surface to be paved. Examples are given wherein 'the resilient particles are formed of a polyurethane elastomer, although vulcanized rubber and natural or synthetic rubber may be used.

[Class 40 (iv).] In telephone instruments, such as table and wall instruments, two parts of an instrument, one at least of which is moulded from a material such as phenol aldehyde condensation product, are secured together by means of screws or the like through the medium of one or more resilient members, arrangements being provided for limiting the amount of strain exerted by the resilient member or members on the two parts when drawn together. The Figure shows the casing 1 of an instrument secured to the base 2 by means of a screw 5 engaging a threaded bush 10 held in a shoulder 3 moulded integrally with the casing, the screw 5 passing freely through a tapped hole in one end of a flat resilient member 6 secured at its other end to the base 2 by a nut and screw 7, 8, or by rivets, or by inserting the end in the base during the moulding of the base. A distancepiece 9 between the member 6 and the bush 10 limits the stress exerted by the member 6. Webs 4 project from the underside of the base 1 on either side of the member 6 to prevent the screw-heads damaging the surface on which the instrument rests. In a modification the resilient member comprises a spring washer.

Title: Improvements in and relating to tuning means for resistance-capacity oscillators

Filed: 1945-09-26
Abstract: 599,950. Valve generating circuits. BRITISH BROADCASTING CORPORATION, and RENDALL, A. R. A. Sept. 26, 1945, No. 26013. [Class 40 (v)] In an oscillator of the phase-shift type having tuning means in the form of a four-terminal network comprising a series arm containing resistance and capacity elements in series and a shunt arm containing respectively equal resistance and capacity elements in parallel, the resistance (or capacity) elements in both arms are variable in steps to provide a plurality of different frequency ranges, and the capacity (or resistance) elements are variable in steps of such magnitude as to provide equal frequency increments for each step over each of the frequency ranges. The four-terminal tuning network comprises a series arm consisting of a variable capacity 12, a set of ten equal capacities 13 and a sub-divided resistance 15. The shunt arm consists of variable capacity 12<1> in series with ten equal capacities 13<1> shunted by a subdivided resistance 151. Corresponding elements in the two arms are equal. The magnitude of capacities 13, 13<1> may be altered step-by-step by means of ganged selector switches 14, 14<1> and resistances 15, 15<1> may be similarly altered by ganged switches 16, 16<1>. The control members of variable capacities 12, 12<1> are also ganged. With this arrangement, if the sub-divisions of resistances 15, 15<1> are chosen to give three frequency ranges, for example 10-100 c/s., 100-1000 c/s. and 1000-10,000 c/s., then in each of these ranges condensers 12, 12<1> will effect tuning throughout the selected range, while movement of switches 14, 14<1> will give ten equal small movements about any frequency corresponding to the setting of condensers 12, 12<1>. In the lowest range, 10-100 c/s., the increments are 0.1 c/s. each, and are proportionately larger in the higher ranges. Alternatively, range switching may be effected by sub-division of capacity in the arms, in which case increment tuning is effected by step-by-step variation of resistance elements. Specification 524,314 is referred to.
