Abstract: 939,818. Photo-electric control of photographic colour printing. ILFORD Ltd. Jan. 24, 1962 [Feb. 1, 1961], No. 3857/61. Class 40 (3). [Also in Group XX] Errors in exposure assessment for photographic colour printing due to secondary absorptions of the photo-sensitive layers are avoided by illuminating a negative with light from an electric discharge lamp so that at least one component of the printing material is exposed by not more than two monochromatic spectral lines and directing part of the light transmitted by the negative through filters on to one or more photo-cells so that no spectral line produces a substantial response from more than one photo-cell. Light of wavelengths 313, 365, 405, 436; 546, 577 and 579 mÁ from a mercury vapour lamp 1 is reflected into an internally reflecting rectangular tube 4, 5, 6, 7, by a dichroic mirror 2. Wavelengths 313 and 365 mÁ are absorbed and wavelength 405 mÁ attenuated by a filter 8 before incidence upon the negative 9. Filters 20, 21 render photo-cells 17, 18 sensitive to 405 and 436 mÁ and 546, 577 and 579 mÁ respectively corresponding to the blue and green sensitive layers of the printing paper. Since yellow and magenta dyes have little secondary absorption in the red, the red light may be a continuous spectrum provided by tungsten lamp 10, 11 in combination with a " cold " mirror 12 and red filter 13. When the cells 17, 18, 19 have received a preset quantity of light, filters 26, 27 and a shutter 25 are inserted in the beam.

Title: Process for the shrinking of webs of non-woven fabrics made in the wet way continuously with their production and webs obtained thereby
IPC: D21F5/00
Filed: 1975-01-29
Abstract: 1477809 Shrinking non-woven webs SOC EN NOM COLLECTIF TENAGIL RHONEPOULENC - TEXTILE - RHONE - PROGIL 29 Jan 1975 [30 Jan 1974 20 Dec 1974] 3990/ 75 Headings D2A and D2B A process for shrinking a non-woven web made in the wet way from a blend of papermaking and texaile fibres, at least some (preferably 5-45% by weight) of the fibres of the blend having a shrinkage or helical crimp potential, comprises subjecting the web to mechanical overfeed, after the web has been dewatered but before it has been dried, to develop sinusoidal folds in the web and then subjecting the web to a mechanical, chemical or thermal shrinking treatment. As shown the folds are developed by using a blade 6 to doctor the web from a press 4, 5 and passing the web to a conveyor 10 moving slower than the machine wire 2. The doctor blade 6 may have an adjustable angle. Alternatively, as in Fig. 2 (not shown) the web can be passed around a vacuum cylinder (33) having a peripheral speed lower than the machine wire speed. The degree of overfeed is desirably 5-100%, the web being 15-80%, preferably 25-60%, dry before the folds are developed. As shown, the web is thermally shrunk in a chamber 11 by subjection to a hot fluid, such as steam, organic solvent vapour, air, carbon dioxide or nitrogen, at 85-115C, the fluid also supporting the web as it travels through the chamber 11. The fibre blend used may include beaten and unbeaten coniferous or hardwood fibres, viscous fibres, rayon fibres, and cellulose acetate, polyamide, polyvinylchloride, polyacrylic and polyester fibres. Particularly useful are bicomponent fibres having a helical crimp potential and made from polyesters, polyamides, acrylic and modacrylic polymers or polyolefins each fibre consisting of two components in side by side relationship, for example the fibres can comprise equal weights of polyethylene terephthalate (m.p. 255-265C) and a copolymer (m.p. 228C) of 95% ethylene terephthalate and 5% dimethyl propanediol terephthalate. The webs formed by the process have a two dimension crepe structure having transverse ridges 0.05-0.4 mm high irregularly spaced 1-10 mm apart with longitudinal undulations 0.05-0.4 mm deep between the ridges, the ratio of the apparent to true densities of the web being below 0.15 at 50 g/cm<SP>2</SP> pressure. Various examples are described including some in which the web is impregnated with a binder such as acrylic copolymer latex or acrylic resin after shrinkage.

Feb. 15, 1932, No. 4424. [Class 56.] Rolling.-A method of making sheet glass consists in rolling a mass of molten glass into a long strip, dividing the strip immediately it is formed into a number of sections, and then turning each section in its own plane through approximately a right-angle and feeding it into a leer. The molten glass is deposited on a receiver 5 and is formed into a strip by a pair of rollers 8. The strip is received upon conveyer tables 19, 20, 21, but it is cut into sections by a cutting-device 18 arranged between the tables and the rolling-mechanism. Each of the tables is composed of a number of rollers which are driven at the same speed, and each table is mounted on a vertical rotatable shaft 30. A leer 40 is associated with each table and is arranged at a right-angle to line of formation of the sheet. When the whole of the sections of the strip are positioned on their respective tables, the tables are rotated through a rightangle into line with the leers, so that the sections of the glass strip are fed into the leers. During the formation of the strip, the rollers of the table 19 are driven at the speed of the rollers 8, while the rollers of the succeeding tables are driven at progressively increasing speeds in order to effect the necessary separation of the sheet sections. After the sections have been received on the tables, the speeds of the rollers are reduced to the speed at which the leer rollers are rotating, so that the strip sections are fed into the leers at the slower speed at which they travel while they are being annealed.

Abstract: 578,675. Sintered alloys containing platinum group metals. MOND NICKEL CO., Ltd., and RHODES, E. C. March 10, 1944, No. 4514. [Class 82 (i)] In the production of an alloy composed of platinum group metals or at least one platinum group metal, and at. least one other metal by sintering a powder mixture, a method of preparing the mixture by making a solution of soluble compounds of the. metallic constituents of the alloy, precipitating these constituents in the form of compounds decomposable to the metals; and thereafter decomposing the precipitate, is characterised in that only compounds of the constituents of the alloy are present in the solution, the platinum group metals being precipitated in the form of complex salts which will decompose on ignition. All the constituents may be produced by ignition of the precipitated mixture, or further reduction may be necessary. Metals other than those of the platinum group may be precipitated as oxide or hydroxide from which the metals are obtained by ignition in a reducing atmosphere. In the preparation of an alloy containing an inert material distributed through it, such material may be obtained by ignition of material precipitated from the solution. For example, where thorium is present in solution as the nitrate it may be precipitated as thorium hydroxide which is decomposed to thorium oxide on ignition. At least one of the metallic constituents or an inert material may be present in the solution in the form of an insoluble suspension of a decomposable compound onto which the complex salt or salts of platinum group metal or metals can be precipitated. The product of ignition may be in sponge-like form which is reduced to a fine powder by attrition. The invention may be applied to the production of sparking plug electrodes.
