Abstract: 547,288. Agglutinated fibrous materials; paper. RAYNER, G. F. (Sylvania Industrial Corporation). Sept. 26, 1940, No. 14580. [A Specification was laid open to inspection under Sect. 91 of the Acts; April 24, 1941] [Classes 42 (ii),.96 and 140) A paper or textile felt is made by admixing non-feltable fibres with 3-20 per cent. by weight of non-tacky synthetic resin fibres which become tacky below the temperature at which the non- feltable fibres are damaged, disposing the mixture as a layer, heating to render the resin fibres tacky and thereafter cooling, thus causing them to adhere to the non-feltable fibres. The non-feltable fibres may be wood pulp, cotton, flax, jute, kapok, silk, cellulose hydrate, cellulose esters, ethers or ether-esters, cellulose ether-xanthates or cellulose xantho-fatty acids, cellulose thiourethanes, natural or synthetic rubber, alginic acid, gelatine, casein, glass, asbestos, mineral wool, natural or synthetic resins or waste regenerated cellulose. The potentially adhesive synthetic resin fibres may be coumarone or indene resins, polystyrene, acid type phenol-aldehyde resins, glycol-polybasic acid resins, drying oil-modified alkyd resins, sulphur olefines resins, dicarboxylic aciddiamine (nylon) resins, poly-butadiene, olefine polysulphides, poly-isobutylene, polydiloroprene, polyvinyl halides and co-polymers of vinyl acetate and vinyl halide, of acrylic acid derivatives and vinyl halide and of styrene and vinyl acetate, mixtures of polyvinyl resins with polyacrylic acid or polymethacrylic acid resins and of polyolefine resins with phenol-aldehyde resins. The fibres may be mixed by carding or by heating the fibres together as in paper making. Plasticizers may be added to the fibres, preferably by incorporation in the resin prior to forming the fibres, and may be removed after heating by extraction with a solvent. The fibre mixture may be shaped before or after heating. Heating may be effected by hot air or water, steam, or hot calendering. The Specification as open to inspection under Sect. 91, describes also the use of urea-, amine- and sulphonamide-aldehyde resin and' polyhydric alcohol-polybasic acid resins. Reference is also made to " woven and " needle felts. This subject-matter does not appear in the Specification as accepted. Reference has been directed by the Comptroller to Specification 10246/38, as. open to inspection under Sect. 91.

Abstract: 374,238. Sieves. McCLELLAND, H., 59, Cambridge Street, Birmingham. May 19, 1931, No. 14696. [Class 117.] A flour dredger comprises a cylindrical container provided with an inverted dome-shaped wire gauze bottom 2 over the surface of which vanes 4 formed of transversely arched or curved metal strips can oscillate. The vanes are set at an angle to one another and are carried on a cranked rod 5 horizontally mounted in holes in opposite sides of the dredger; the vanes being actuated by pushing on the upper end of a bar 6 of which the lower end is secured to the cranked portion of the rod 5. The bar 6 slides on the rim of the upper edge of the dredger and a tongue 10 projecting from a guide member 8, and the bar is returned to its upper position by a spring 9 secured between the guide 8 and the cranked portion of the rod 5. A strip 11 secured to the bar 6 has downwardly bent ends which abut against the guide 8 and limit the movement of the bar in both directions. The upper end of the bar lies just above the handle of the dredger and is bent to form a thumbpiece 7. The bottom of the dredger may be formed of perforated sheet metal, and the invention is applicable to any powder container in which the material passes through an aperture or apertures therein. According to the Provisional Specification the bar 6 is formed from strip of sheet metal folded over at the middle, the thumb-piece 7 being formed at this middle portion and the ends being provided with holes engaging the cranked portion of the rod 5.

Title: Improvements in or relating to sewing machines
IPC: D05B3/14
Filed: 1943-09-08
Abstract: 579,253. Sewing-machines. NEWTON, E. P. (International Button Hole Sewing Machine Co.). Sept. 8, 1943, No. 14736. [Class 112] A machine for sewing four, or two, hole buttons or the like on to material, such as described in Specifications 476,039 and 476,080, is provided with cam-operated means to move a needle bar 21 into position x, Fig. 1, to form the stitches s<1>, Fig. 2, and then into position y to form the stitches s<2>, the work remaining stationary. A single cam 40 has two grooves 78, 79, Fig. 5 which are alternately engaged by pins 73, 74, connected as shown in Fig. 9, a ramp 82 depressing one pin 73 and automatically raising the other pin 74. The needle-bar 21 is reciprocated in bearings 23, 230 by mechanism 9 actuated by a shaft 89. For a four-hole button a carrier 25 is oscillated laterally during successive descents of the needle 20 to cause the needle to pass alternately through the holes a and b, Fig. 2, after which the carrier is shifted longitudinally to bring the needle into the plane of the other holes c, d. The carrier slides in a groove bearing 26, and is oscillated laterally about the axis of a pivot 27 by a link 30 having a pin 31 projecting into a slot 32 in the upper face of 25. A stud 33, at the other end of link 30, operates in a slot 34 in a lever 35 which is oscillated about a pivot 36<1> when one or other of pins 36, 37, is engaged in one of the cam grooves 38, 39. Manually-operated means are provided to select either pin 36 or 37, according to the number of stitches required, since the groove 38 has more indentations than the groove 39 and thus produces more stitches per revolution of the cam. The cam 40 is also provided with grooves 42, 43, which, through linkage (not shown) control the operation of loopers 22. The degree of longitudinal movement of 25 is determined by the position of a link 52 pivoted to 25 by a pin 53 at one end, and to a block 57 in a grooved lever 59, at the other end. The lever 59 oscillates about a shaft 60, but when the block 57 is moved along the groove 58, by manual means, to coincide with the shaft 60, there will be no longitudinal movement of 25, as when a two-hole button is being stitched. The pins 73, 74, are carried by an arm 71 keyed to the shaft 60, and alternately engage the grooves 78, 79, as described above. Notches a<1>, d', cause movements of the arm 71 which turns the shaft 60 and moves the lever 59. A pin 90 engages one or other of two grooves in the arm 71 to prevent lateral movement of the arm when the pins 73, 74, are being changed over by contact with one of the ramps 82.

Abstract: Metallic and nitrogen-containing contaminants are removed from hydrocarbon oils, for example a crude oil, or a kerosene, gas oil, or lubricating oil fraction of petroleum, by treatment with anhydrous hydrogen fluoride, characterized in that liquid propane or n-butane containing anhydrous hydrogen fluoride in an amount not exceeding 1% wt., and in any event not more than that which will dissolve in the propane or n-butane, is contacted with the hydrocarbon oil in a ratio of from 1 to 12 volumes of liquid propane or n-butane per volume of hydrocarbon oil at a temperature within the range 0-150 DEG  C. and at a pressure which maintains the hydrogen fluoride component as well as the propane or n-butane in liquid phase, and said contaminants are thus precipitated, while avoiding the formation of a dual phase liquid system, the resultant precipitate being separated from the treated oil. Pressures up to 30 atmos. are generally sufficient.
