Title: Improvements in or relating to the construction of foldable articles of furniture orthe like
IPC: A47B3/02
Filed: 1931-03-25
Abstract: 375,391. X-form furniture and other articles. BURNS, G. V., Parker Hill, Rathmines, Dublin. March 25, 1931, No. 9129. [Classes 52 (i), 52 (ii), 52 (iii), and 52 (v).] Foldable and demountable articles of furniture or the like comprise X-form legs, pivoted intermediately, the upper ends of which are formed with tenons entering slots or trenchings in the upper member, the weight of which is supported on the shoulders adjacent to the tenons. In modifications, the tenons are reinforced by hinges. The improvements are applicable to the making of chairs, tables, desks, beds, bookshelves, and temporary structures such as portable platforms. As shown in Fig. 1, the legs 1, 2, connected by a pivot pin 3, have at their upper ends tenons 4, 5 adapted to enter trenches or mortices 10, 7 formed, one in a locking-piece 9 and the other in a bearer 6 which preferably is secured to or forms part of a table top. The trenching 7 is preferably closed by a locking- piece 14 shown in dotted lines, but this may be omitted, the necessary rigidity being afforded by bracings 15, 16 connecting the X-frames. The dimensions of the table top preferably are such that the top may be placed inside the folded frame. In modifications, the forms of the parts 4, 10 may be varied ; the mortices 10 may be made partly in the part 9 and partly in the bearer 6, the tenon being formed centrally on the legs 1, 2 ; the trenching 10, Fig. 7, may be continued up to a recess 18 in the underside of the top 17, forming a locking device and rendering superfluous the bracings 15, 16, Fig. 1. To enable the tables &c. to be folded up without detaching the parts, the locking- piece 9, Fig. 8, may be slidably attached to the bearer 6 by pin-and-slot connections 20, 21, and the parts 9, 1 connected by hinges 22. The ends of the tenons are bevelled, as shown by dotted lines, to enable them to enter and leave the trenchings. In another form, the parts 6, 1 are connected by a pin-and-slot device instead of the hinge 22. School desks are made by supporting an inclined desk slope and a seat on such X-form frames, which in turn are supported by a base to which the frames are connected by tenon joints as above described. Book-shelves are made by mounting a series of platforms, one above another, on such X-form structures.

Title: Improvements in or relating to the depilation of animal hides
IPC: C14C1/06
Filed: 1967-02-27
Abstract: 1,170,801. Depilating, bleaching and tanning or tawing hides and skins. FARBWERKE HOECHST A.G. Feb.27, 1967 [Feb.25, 1966], No. 9194/67. Addition to 1, 049, 706. Heading C6C. The process according to the main invention is improved and expedited in that keratin-containing parts, such as epidermis, hairs, wool and scales, are removed from soaked or moist hides, pelts and skins, e.g. snake skins (all hereinafter referred to as hides) by subjecting them, e.g. in a revolving drum, to the action of chlorine dioxide until said parts have become jellified and softened, and then to treatment with an alkaline, aqueous liquor having a PH of at least 7À5, preferably above 8À0, or alternatively to treatment with gaseous ammonia, until said parts are loosened and detached from the hides. Preferably, chlorine dioxide gas free from oxygen is used, e.g. chlorine dioxide mixed with an inert gas, such as nitrogen or carbon dioxide, to reduce the risk of an explosion. The chlorine dioxide gas may be produced by the action of concentrated sulphuric acid on an alkali metal chlorate, or by reacting chlorous and nitrous acids. A mixture of chlorine dioxide and carbon dioxide may be generated by reacting chlorous and oxalic acids. The chlorine dioxide may be generated in situ from a substance which furnishes chlorine dioxide, such as sodium or potassium chlorite, in a paste or an acidified, aqueous depilating liquor having a pH between 1À5 and 3À5, which liquor may contain a baffer salt, such as sodium dihydrogen phosphate, sulphate or acetate. Depilation may be completed and bleaching may be effected by treating the hides, in an acidic liquor, with more chlorine dioxide. The depilated and bleached hides may be chrome-tanned or alumtawed.

Title: Improved manufacture of adhesives
IPC: C09J189/00
Filed: 1919-04-17
Abstract: The proteins contained in oil-seed residues, particularly from hemp seed or castor beans, are extracted by dilute alkali, and the solution is either evaporated to dryness or precipitated by acid in known manner, and the dried extract or precipitate is converted into an adhesive by mixing it with one or more bases, such as an alkaline-earth hydrate or magnesia, and an alkali salt, such as sodium fluoride or arsenate, which is slowly decomposed by the base to give caustic alkali, and then mixing this mixture with dilute caustic alkali to form a stiff jelly.  Instead of using the dry acid-precipitated proteins, they may be redissolved in caustic alkali and the solution evaporated to dryness and mixed with the ingredients mentioned above.
