Abstract: 219,662. Junkers, H. July 24, 1923, [Convention date]. Addition to 145,496. Riveting.-In a method of riveting hollow bodies in which the rivet is inserted from the outside and hammered against an internal abutment, the distance between which and the wall of the body is continually diminished during riveting as described in the parent Specification, the article is supported externally and the distance between the abutment and the wall is varied by pressing the rivet together with the adjacent parts of the wall against a fixed abutment, bearing against the externally supported wall, the article being elastically compressed along the line of impact. In making a riveted lap joint in a tube 1, the tube rests on a support 2 opposite the riveting point and a fixed abutment 4 carried by a part 3 is inserted by a rod 14, and after the rivet 6 is inserted it is forced by a cam 12 adjacent the end 5 of the abutment, the tube at the same time undergoing elastic deformation, as shown in Fig. 3. The parts of the wall are pressed together by a spring- controlled clamp 7 to prevent the material of the rivet shank from being pressed between them. The clamp is slotted at 10 to engage a pin 11 to prevent turning of the clamp and the forward end of the clamp preferably has a slot 9 so that the apparatus may be pushed into position after insertion of a rivet blank. In cases where the tube cannot be deformed sufficiently for the complete heading of the rivet two or more abutments of different heights may be used in succession.

Title: Thread cutting attachments
IPC: B23G1/46
Filed: 1973-03-29
Abstract: 1359980 Thread cutting apparatus SCANDINAVIAN PAPER CONVERTING AB 29 March 1973 [29 March 1972] 15280/73 Heading B3N A thread cutting apparatus has a driving member 1 and a driven member, sleeve 6 and tool holder 11. Sleeve 6 is axially fast with member 1 and is driven by a bolt 35 that engages in recesses 4 in member 1 and in L-shaped recesses 36 in sleeve 6. Drive between the sleeve and the tool holder is by balls 14 engaging in grooves 9 and 13. In operation when a tool reaches the bottom of a blind hole the torque build up between sleeve 6 and bolt 35 is such that knee portion 36<SP>1</SP> forces the bolt downwardly and out of engagement with recesses 4 and drive to the tool holder stops. Piston 31 moves downwardly so that grooves 34 therein holds bolt 35 in the lower portions of slots 36. Bolt 35 also projects into slots 43 in ring 28. These slots are similar to slots 36 but are positioned axially slightly below them. Thus when the bolt engages the lower part sleeve 28 is freed upwardly moving balls 30 into engagement with ring 5. Member 1 is still rotating and thus rotation of the balls causes reverse rotation of ring 28. Drive to sleeve 6 and thus tool holder 11 is by pins 26. The torque at which the drive to the tool holder is broken is adjustable by means of thread 17, ring 16, thread 20 and ring 19. The threads may be of different hand and pitch.
Patent GB-781716-A (GB)
Title: Bleaching method
IPC: D06L4/26
Filed: 1955-05-27
Abstract: Fibrous material is impregnated uniformly with an acid, treated superficially with a chlorine-containing bleaching compound and then heated.  The material may be cotton, flax, hemp, jute, nylon, perlon or "half stuff" used in paper manufacture.  The process may follow a desizing treatment with basic reagents, in which case the customary neutralization of the basic compounds, e.g. caustic soda, is effected with an excess of acid, e.g. formic or phosphoric acid.  The material is then impregnated with the bleaching compound, e.g. sodium chlorite or hypochlorite solution, which may contain formic acid and which may be heated, and the material is afterwards heated.  It is stated that, since they are saturated with an acid, the fibres are only treated superficially by the bleaching compound.  Rayon fibres may be desized with a composition comprising sodium carbonate, trisodium phosphate, sodium hypochlorite, and a wetting agent and may then be treated with a near-boiling solution of formic acid prior to the bleaching step. Cellulose fibres may be treated in a flocculent state.
