Patent GB-445701-A (GB)
Title: Improvements in the production of printing inks comprising the dispersion of pigments in oils
IPC: C09D11/03
Filed: 1934-10-13
Abstract: Printing-ink is produced by dispersing a pigment in an oil, to which is added a salt of a multiple unsaturated higher fatty acid with an alkali, ammonia, or organic base, in an amount, e.g. not more than 5 per cent calculated on the weight of the pigment, sufficient to increase the dispersion of pigments in the oil. The acid component of the salt may be linseed oil fatty acid, or the fatty acids of chinawood oil, whale oil, and liver oil, including linoleic, linolenic, eleostearic, and clupanodonic acid. As organic base component there may be used mono-, di,- and tri-ethanolamine or propanolamine.  The salt may be neutral or acid.  The addition results in smoothness and easier printing quality of the ink, and a lowering of viscosity particularly when mineral oil is present, and enables the amount of pigment to be increased.  In an example a printing ink containing Milori blue, methylene blue varnish, aluminium hydroxide in oil, blown linseed oil varnish, and manganese borate, is mixed with a small quantity of triethanolamine eleostearate, or the triethanolamine salt of linseed, menhaden, or whale oil fatty acid.  Potassium, sodium, or ammonium salts may be used.  Specification 183,177, [Class 95], is referred to.  The Specification as open to inspection under Sect. 91 comprises also the use of salts of bean oil fatty acid, and of salts in which the acid is neutralized to the extent of only one fourth to one half.  An example is given of a printing ink containing soot, mineral oil, stand oil, and asphalt, to which is added a small quantity of the three-quarter acid salt of linseed oil fatty acid and potassium. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to circular knitting machines
IPC: D04B1/00
Filed: 1924-12-10
Abstract: 242,801. Lombardi, V. Dec. 10, 1924. Circular machines; knitted fabrics.-Multicolour work, a fragment of which is shown in Fig. 1, is knitted on a machine provided with four sets of needles, which differ as to the length of the butts and also as to the position of the butts relative to the hooks. Fig. 1 shows a group of 54 needles and their cams. Needles 1 - - 14, 21 - - 34 and 41 - - 54 have butts which are operated between surfaces 70, 71 by cams 61 - - 66 while the remaining needles have butts operated by cams 74 - - 79 between surfaces 72, 73. The butts of the even-numbered needles (shown shaded) are longer than those of the odd-numbered needles. The cam 61 which is only wide enough to engage the long butts, elevates groups of even-numbered needles as shown to a level at which their loops are not cleared; on the subsequent descent under the influence of cam 62 they take the yarn 84, which is missed by the oddnumbered needles. The cam 63 acts on the evennumbered needles similarly to the cam 61, while the cam 64 raises all the needles to beyond the clearing level and thus causes the yarn 84 to take a zig-zag course in front of the even-numbered needles and behind the odd-numbered needles. The cam 65 causes all the needles to take the yarn 83 which is thus knitted on the needles 1 - - 14, 21 - - 34 and 41 - - 54 with a yarn 84 sandwiched in as shown in Fig. 1, the centre wall of loops being drawn by an even-numbered needle. The needles 15 - - 20 and 35 - - 40 will be caused to knit a fabric composed of loops of yarn 84 with the yarn 83 sandwiched in between by cams 76, 74, corresponding to cams 61, 63, and raising long-butted needles only cams 77, 75, corresponding to cams 62, 65, and wide enough to operate all needles and the clearing cam 78. If the cams 78, 64 are lowered out of action and other cams 66, 79 are raised into action, the yarns 83, 84 will interchange positions whereby a checkered effect is obtained. If cams 66, 78 are operative and cams 64, 79 are inoperative, all the needles will draw loops from the yarn 84 and sandwich in the yarn 83, and if this arrangement is reversed the yarn 83 will be knitted all round and the yarn 84 will be sandwiched. When all the cams 64, 66, 78 and 79 are raised, ordinary fabric is produced. Fig. 3 shows means for moving the cam 64 consisting of an upright sliding rod 95 carrying the cam 64 and connected by a ball-andsocket joint to an arm 105, pivoted at 106. Hooked members 107, 109 on the arm 105 are engaged by discs 108, 110 on a vertically movable patterncontrolled support 111 to move the arm 105 between adjustable stops 112, 115. A spring member 113 co-operating with a curved surface 114 retains the arm 105 in position. The other cams are moved similarly.

Abstract: 941,813. Mirror systems. L. E. HUNT. Aug. 18, 1961 [Sept. 15, 1960], No. 29932/61. Heading G2J. [Also in Division F4] A mirror system e.g. for concentrating solar energy (see Division F4) comprises two systems of reflective surfaces, each producing the effect of a two-dimensional concave curvature, one system which has a greater focal length serves as a collector system and the second system which is positioned at a point located at a distance from the focal line of the collector system equal to its own focal length acts as a secondary reflector system, the effective focal lines of the two systems being normal to each other. As shown, the secondary reflector 3 is smaller than the collector 2 and is positioned above the collector. The curvature of both reflecting surfaces corresponds to a parabola although the curvature need not lie about any line of symmetry ( Fig. 3 not shown) of the complete parabola. Both systems may be mounted on tracks and they may also be tiltable in any direction. In an embodiment, the reflecting surfaces comprise a number of relatively narrow flat reflecting members placed end to end to approach in effect a parabola (Fig. 4 not shown). These reflecting members may be so mounted that the curvature of the parabola may be altered to any desired shape.

The board may comprise one layer each of foamed resin and mineral fibre or a sandwich structure with a layer of mineral fibre between two sheets of foamed resin or vice-versa. The foamed resin may be produced from a polymer of propylene, butadiene, styrene, vinyl toluene, α-methyl styrene, acrylonitrile, vinyl chloride, vinyl acetate, methyl acrylate, methyl methacrylate or ethyl acrylate, and the thermoplastic resin film may be of polyvinyl chloride or polyethylene: The flexibility of the insulation material may be increased compressing the foamed resin sheet. Alternatively the composite board may be in relatively small rectangular pieces laid between the thermoplastic resin films which are sealed together between each piece. The two thermoplastic resin films may be heat- or adhsive-sealed along the edges. A margin may be provided by sealing the films together adjacent the board and along their outer edges, a line of perforations being provided between the two sealing lines. The components of the composite board may be bonded together and/or to the thermoplastic resin films by means of an adhesive, e.g. a polyvinyl acetate, waterglass or bitumen adhesive, which may be applied in longitudinal discrete bands.
