Abstract: Dye-receptive graft polymers comprise a polyester polymer substrate having graft polymerized thereto units of an ethylenically unsaturated monomer which confers dye affinity to the resulting product, e.g. (a) vinyl lactam monomers, particularly vinyl pyrrdidones; (b) sulphonated alkenyl aromatic monomers and alkali metal salts or esters thereof; (c) sulphonated olefines and alkali metal salts or esters thereof; (d) sulphonated esters of acrylic and methacrylic acids and alkali metal salts or esters thereof; (e) sulphonated N-substituted acrylamides and methacrylamides and alkali metal salts or esters thereof; (f) vinyl pyridine and lower alkyl derivatives thereof; (g) amino-substituted alkenyl aromatic monomers; (h) aminoethyl acrylate and methacrylate and N-methyl and -ethyl derivatives thereof; (i) alkenyl aromatic monomers ar-substituted by polyglycol ethers; (j) polyglycol esters of acrylic and methacrylic acids; and (k) N-vinyl-3-morpholinone.  The grafting may be effected by impregnating the polyester with the monomer or a solution or dispersion thereof followed by polymerization of the monomer by means of a free radical catalyst or high energy irradiation, e.g. beta or gamma rays or the radiation from electron beam generators.  The polyester substrate is preferably in shaped form, e.g. a filament. The examples describe the grafting on to a polyethylene terephthalate substrate (cloth) of N-vinyl pyrrolidone, a mixture of N-vinyl pyrrolidone and 2-sulphoethyl methacrylate, 2 -vinyl pyridine, N-vinyl-3-morpholinone and a polyglycol monoacrylate.  The resulting products have good dye-receptivity.  Reference has been directed by the Comptroller to Specification 805,513.

Title: Improvements in or relating to apparatus for making compressed straw or the like panels and boards
IPC: B27J1/00
Filed: 1929-01-12
Abstract: 323,381. Tchayeff, S. Oct. 3, 1928, [Convention date]. Materials, special; making building-blocks. - Boards or panels of compressed straw, reeds, or the like are formed by compressing the material in a mould a between pairs of longitudinal reinforcing wires d, the latter being tied together by hooks f passed through the material. An apparatus for engaging the hooks with wires comprises a forked slide 5 which is operated in a bed plate 4 to carry the hooks through the material, the mould a being formed with openings e for the passage of the slide. The slide carries towards its forward end a fixed member 9 and a member 8 which is pivoted at 10 and is held towards the member 9 by by a spring 11. In use, a hook is carried between the members 8, 9, the spring 11 yielding when the slide has penetrated the material to allow the hook to snap round the upper wire d. A pile of hooks is carried by a vertical bar 2, the lowest hook resting upon a tongue 13 when the slide 5 is in the mean position shown in Fig. 5. The tongue 13 is carried by a lever 15 which is pivoted at 16 and carries at its rear end a roll 17. Below the bed plate 4 is pivoted a member 20 which is profiled at its upper end 23 to form a continuation of the bar 2 and is urged into engagement with the slide 5 by a spring 22. When the slide 5 moves forwardly to insert the hook already in position between the members 8, 9, the roll 17 engages a cam slot 19 in the slide, allowing the tongue 13 to swing outwardly, so that the lowest hook on the bar 2 falls upon the slide 5. As the slide returns, the tongue moves in again, supporting the remaining hooks. When the slotted part 7 of the slide comes above the member 20, the latter can rise into prolongation of the bar 2, so that the separated hook is supported by its upper part 23. When the slide commences a new forward movement, the member 20 is moved downwardly by its engagement with the unslotted part of the slide, and the hook is carried forward by the members 8, 9. A pivoted lever 24 serves to expel from the slide a hook which has failed to engage the wires d.

[Also in Groups XXI and XXII] A cartridge case or like container is made by winding a sheet of metal or other material into a tube and securing one end of the tube in a frusto-conical groove of a base 4, a liner 6 of plastically deformable material being engaged in the groove and pressed into engagement with the base and the tube. The liner 6, which may be of lead or a synthetic resin, has a flat portion 6c, Fig. 2, and a depending flange 6b and together with the base is placed on an anvil 9 having a locating flange 9a and an axial projection 9b extending into an axial passage 4a in the base 4. A shaft 10 rotatably mounted in a bearing 11 carries the anvil and a rotary tool 7 is mounted in a bearing 13 movable obliquely downwards in the direction of the groove. After placing a weight 12 on the liner, the tool is lowered to engage the flange 6b, and while thus engaged the oblique movement of the tool causes both the anvil and the tool to rotate. When the flange has been bent, the tool 7 and weight 12 are withdrawn and the central part of the liner is removed by a circular cutting tool (not shown). The lower edge of the tube is then inserted in the groove and the groove is closed by pressure.
