IPC: F16D1/08
Filed: 1921-06-13
Abstract: 168,586. Krupp Akt.-Ges., r. Aug. 28, 1920, [Convention date]. Securing stirrers on shafts. - The stirrers of a mixing or agitating device are connected to the driving-shaft by pouring between the hub of the stirrer and the shaft material, such as molten lead, which sets hard. The hub b<1> of the stirrer has a square opening b<2> which leads into a chamber b<3> of square cross-section. The lower end a<1> of the shaft A is also of square cross-section and of the same size as the opening b<2>. The stirrer is fixed by inserting the end a<1> of the shaft through the opening b<2> into the chamber b<3>, and then turning it through 45‹. The chamber is then cast full of material which sets hard and thus prevents movement between the stirrer and the shaft.

Title: Improvements in or relating to textile fabrics
IPC: D03D15/00
Filed: 1942-11-19
Abstract: 564,192. Coated fabrics. FINLAYSON, D., and CRAWSHAW, H. Nov. 19; 1942, No. 16374. [Class 140] [Also in Group IX] A fabric, suitable for use as the basis of a varnished fabric for electrical insulation, comprises in both weft and warp, yarns of high tensile strength and high extensibility, the yarns being so woven together and that those of low extensibility are not interlaced with one another to any substantial degree but depend for their maintenance in the fabric structure on the presence of the yarns of high extensibility. In an example, the warp yarns comprise 30 denier cellulose acetate filaments made by stretching and subsequently saponifying. These yarns alternate one by one with 45 denier cellulose acetate filaments which are unstretched and unsaponified. Similar yarns are used, two by two, in the weft and the weave produced is a 4-shaft satin fabric with 100 ends per inch in the warp and 140 picks per inch in the weft. This fabric is treated with an insulating varnish of glycerol/phthalic-anhydride resin modified with linseed oil and containing a hydrocarbon thinner. The finished fabric may have a thickness from 4 mils. The weave may be a plain weave, the two kinds of yarn alternating one and one in both warp and weft. The stronger yarns may have a tenacity exceeding 4 grms. per denier with an extensibility of 5-6 per cent, while the extensibility of the weaker yarn may be about 15 per cent. Thermoplastic yarns, e.g. of polyvinyl esters or ethers, or a copolymer of vinyl acetate and vinyl chloride, may also be used for the high extensibility'warp and weft yarns. Specifications 438,584, 438,587, 438,656, [all in Group IV], and 443,773 are referred to.

Abstract: 1320628 Internally-coated open-cellular material JOHNSON & JOHNSON 21 May 1971 [22 May 1970] 16380/71 Heading B2E A uniform cohesive sheet for use as a bandage, tape or closure comprises (a) a porous, resilient open-cellular web of cell density 10-120 cells per running inch, the cellular surface area on at least the exposed exterior thereof occupying less than 15% of the total area of the exterior when the web is non-compressed, and (b) a non-pore-filling cohesive coating on the cell surfaces substantially throughout the web whereby compression of the sheet substantially increases the coated cellular surface area at the exposed exterior and thereby increases the cohesion characteristics of the sheet. The open-cell web may be a polyurethane-, vinyl-, styrenebutadiene- or rubber-based-foam and may be prepared from a closed cell foam by chemical treatment, bursting or perforating. The cohesive coating may be natural rubber or cis-polyisoprene and tackiness of the cohesive may be eliminated by addition of silicone fluids. The coating is applied to the foam by means of rollers followed by compression of the sheet, or by first spreading the cohesive on silicone-coated paper and rolling the foam placed on the coated paper with another sheet of silicone-paper on top to force the cohesive through the foam. The cohesive sheet can be reinforced by laminating with strengthening fabrics, coatings or fibres.

Abstract: 690,497. Counting-apparatus. VEEDERROOT, Inc. July 3, 1950 [July 19, 1949], No. 16521/50. Class 106 (i). A change-speed gearing for counting- apparatus comprises the combination of a drive-shaft adapted to be rotated by a meter, gears mounted to rotate with said driveshaft, a second shaft having a series of similar gear-wheels mounted thereon and driven at varying speeds, at least one further shaft carrying a slidable but non-rotatable gear for meshing selectively with any of said similar gears, said slidable gear being associated with an indicating member. The device is mounted in a frame comprising a base 11, Figs. 1 and 4, and a raised platform 12 supported by pillars 13, 14 and 15. A non-return vertical shaft 20 driven from a liquid dispensing meter, not shown, passes through the frame and is journalled in the base 11 and the platform 12. A vertical shaft 25 also journalled in the base 11 and the platform 12 is driven from the shaft 20 through gears 22, 23, Fig. 1, and carries at its top a bevel gear 26 which drives the registering mechanism, not shown. A cone-like set of nine gears 30 of varying diameters are fixed to the shaft 25 and drive, directly in the case of lowest wheel 30 and through pinions 33 for the other wheels, corresponding uniform gears 32 freely rotatable on the shaft 20. The gear ratios are such that the nine gears 32 are driven at speeds varying from 1 to 9. Any of the gears 32 may be engaged by three gears 40, 41, 42, Fig. 4, vertically movable but non-rotatably mounted on vertical shafts 35, 36, 37 which are therefore rotated, as desired, at speeds varying from 1 to 9. The outputs of the shafts 35, 36, 37 are transmitted in the ratios 1-10-100, by differential mechanisms to a gear 51, Fig. 1, rotatably mounted at the top of the shaft 35. Each of the gears 40, 41, 42 is carried between the limbs of a U-shaped member 75 vertically slidable on the corresponding shaft 35, 36, 37 and having a vertical rack 78, Fig. 4. The setting of the gear 40, Fig. 4, is transmitted via the associated rack 78, a gear 105 on a horizontal shaft 100, a pinion 90 to a numeral drum 84 rotatable on a horizontal shaft 80. A gear 106 fixed to the gear 105 imparts horizontal sliding movement along the base 11 to a rack 107 which through a gear 108 on a horizontal shaft 101 and a pinion 93 rotates a numeral wheel 89 on a horizontal shaft 81. In the same way the vertical setting movements of the wheels 41, 42 are transmitted to the pairs of numeral wheels 85, 88 and 86, 87 respectively through the corresponding vertical rack 78 and horizontal racks 112, 118 respectively. Spring- pressed plungers 121, Fig. 6, co-operate with sawtooth on the bottom of the racks 108, 112, 118 to align the numeral 84-89 correctly. The plungers 121 are normally locked by a slide 123 but are freed by inward movement of the slide.
