Title: Improvements in or relating to the production and mounting of cylindrical liners such as brake drum liners
IPC: B21D53/30
Filed: 1942-09-30
Abstract: 560,387. Making cylindrical liners. CATT, F. A. Sept. 30, 1942, No. 13748. [Classes 83 (ii) and 83 (iv)] Brazing; uniting by fusion.-Cylindrical liners for brake drums, engine cylinders or for similar tubes or drums, are made by converting a metal strip such as of carbon or alloy steel by a rolling machine or other forming tool into cylindrical form of length slightly less than the circumference of the liner, then clamping it on a cylindrical jig or mandrel 13 with its ends over a groove 14 or a rectangular groove in the jig and welding or brazing the edges together by melting, preferably by an oxy-acetylene blowpipe, a welding or brazing rod to fill the space between the edges with a slight excess of metal both inside and outside and then machining away the excess metal. The cold liner is then inserted into a heated drum which is allowed to cool to contract on to the liner to embrace the same. The drum 15 and liner 12 are then drilled and tapped in two or more places into which studs 16 are screwed, the ends of the studs cut off and riveted over as shown in Fig. 4 and then machined off at the same time as the bore of the liner is bored or ground internally to leave a smooth surface on the inside of the liner. In order to weld from the inside the groove in the mandrel is deepened so as to accommodate the welding appliances.

Title: Improved manufacture of phenolic condensation products
IPC: C08G8/28
Filed: 1923-05-24
Abstract: Phenol-methylene condensation products are produced by heating an aldehyde dichloride with a phenol in the presence of ammonia, the proportions of the aldehyde dichloride and phenolic body being such that approximately 1.5 phenolic groups are present for each methylene group.  The aldehyde dichloride used is generally methylene chloride, but ethylidene and propylidene chlorides may also be employed.  The ammonia is preferably present in excess; compounds of ammonia, such as methylamine or ammonium carbonate, may replace the ammonia. Phenol, cresols and naphthols are mentioned as suitable phenolic bodies.  The fusible, soluble resin formed by the condensation is washed with water to remove the ammonium chloride, excess of phenol then eliminated by boiling or by blowing air through the heated resin, and finally a hardening agent, such as hexamethylenetetramine or formaldehyde or formaldehyde and ammonia, is added and the product converted by heat into the insoluble and infusible product.  Fibrous or other fillers may be incorporated in the resin at any stage. Specifications 9291/14, 119,253 and 196,265 are referred to. Aldehyde dichlorides are obtained as by-products in the preparation of methyl chloride by chlorinating methane or natural gas.

Abstract: 163,338. Frenzel, T. May 19, 1921. Pile fabrics.-Pile fabrics or carpets having pile threads or tufts knotted round warp threads 25, 26, Fig. 25, are produced in a carpet loom by first weaving a preliminary fabric with warp threads in the required order to suit the tufts in the carpets to be woven and then inserting chenille strips, Fig. 2, cut from this fabric as wefts over crossed ground warp threads 25, 26, Figs. 16 and 17, of the carpet being woven, the projecting tuft ends 3 from the chenille strip being then gripped and twisted around the intersections of these warp threads, as shown in Fig. 18. The tufts are then released and the warp threads caused to uncross by beating-up the reed 27, whereupon the tufts knot around these warp threads. A ground weft 28 is then inserted, and the cycle of operations described is then repeated, the core threads 1 of the chenille strips being withdrawn after completion of the knotting. The knotting - devices employed may comprise discs 5, 6, Figs. 3, 4, and 5, mounted on shafts 18, 19, 20, the discs being connected in pairs at their lower portions by rivets 4, whilst the pairs of discs are spaced apart, in accordance with the reed spacing, by spacing-rings 21. Flat rods 10, fitting between the discs, are moved from vertical to horiozntal positions, so as to separate the upper parts of the discs to receive the tufts, by links 11 connected to a bar 22. The discs have recesses 7 to receive the chenille strips. The modified knotting- device shown in Figs. 16, 17, and 18 comprises discs 12 riveted to the lower parts of discs 5, which have rods 13, 14 operated by rods 24, 23. Clamping-tongues 8 on the discs can be forced apart to receive the tufts by wedge-shaped members 16 operated by levers 15 and links 17 from the lever 14. The warp threads 25 are first raised, and the discs are inserted between these raised threads, and then moved sideways and afterwards. lowered to cross the threads 25 over the threads 26. The threads. 25, 26 are then so operated as to bring crossed parts thereof into recesses 7 of the discs; a chenille strip is next laid aa a weft in these recesses; the clamping- tongues 8. are caused to grip the tufts, the discs are turned into the position shown in Fig. 18, the tufts are then released, the reed 27 beats up, and, finally, a ground weft 28 is inserted. The knotting-device 5, 6, Figs. 3, 4 and 5, operates somewhat similarly, but grips the tuft ends 2 as well as the tuft ends 3.

Filed: 1919-06-04
Abstract: 150,792. Sloper, T. June 4, 1919. Vulcanizing, pressing-devices for; flexible wrappings.-Pressure is applied to tyres or similar ring-like articles during vulcanization by means of a resilient band which lies within or encircles the article, the ends of the band being formed into strips which extend past each other side by side, and are attached to means for forcing the ends of the strips in opposite directions. A tyre-cover or the like B on a mould A is encircled by a band D of steel, wire gauze or the like, the ends of which are formed into strips D<1>, D<2> which extend past each other and leave the surface of the tyre tangentially. The ends of the strips are attached respectively to pins E<1>, E<2>, the pins E<1> being carried by a strut E, and the pin E<2> being carried by screw bolts E<3> passing through openings in the strut E, and held by nuts E<3>* which on being tightened cause the band D to exert pressure on the tyre B. When the tyre is formed on the inside of the mould, the ends of the strips are attached to cross-bars against which bear cams carried by the strip, so that on placing the strip inside the tyre, and rotating the cams, the ends of the strips are forced towards one another. To facilitate slipping, and to protect wired-edges from pressure, and also to save as a guide for the wires, a band C of canvas and rubber or the like of such width and thickness that its edges lie along the wires. and its upper surface level with the top of the wired edges, is placed between the tyre and band D. This band may also be used when other means for producing pressure, for instance the usual wrappings, are employed, and if desired, may be wider than the tyre with grooves for the edges. A plate F may be placed between the tyre and band at the joint of the latter to prevent marking.

Abstract: 769,172. Turning gear. BENDIX AVIATION CORPORATION. May 17, 1955 [June 23, 1954], No. 14243/55. Class 7 (5). In an engine starter comprising an electric motor with an armature 3 that is longitudinally movable into and out of centered position with respect to the field 2, an armature shaft 4, a pinion 8 slidably and rotatably mounted on and with the latter into and out of mesh with an engine gear 9, means for actuating the pinion from the shaft 4 including a screwshaft 17 rotatably and slidably mounted thereon, a nut 21 threaded on the screwshaft 17 and rigidly connected to the pinion 8, an overrunning clutch connection 18, 19 from the shaft 4 to the screwshaft 17 and a spring 37 urging the shaft 4 toward its decentred position, there is provided means, including a centrifugal plunger 42 mounted on the shaft 4 for preventing decentring movement of the latter below a predetermined speed. The pinion 8 is secured to a barrel 22 that is fixed to the nut 21 whilst the screwshaft 17 is provided with overrunning clutch teeth 18 cooperating with similar teeth 19 on a driving clutch member 16 to which is attached an anchor plate 15. The drive spring 14 connects the plate 15 with another plate 13 mounted on a sleeve 11 that is fixed to the shaft 4. A ring 23 in a groove in the sleeve 11 and a washer 29 abutting a shoulder 28 serve to limit movement of the clutch member 16 toward the engine gear 9, the ring 23 also maintaining the spring 14 under an initial compression. Meshing movement of the screwshaft 17 is defined by a stop 31, a spring 33 interposed therebetween urging the clutch teeth into engagement. A spring-loaded detent 36 coacts with the screwshaft to retain the pinion in the idle position when the drive is inoperative whilst shoulders 35 on the ends of the screwshaft threads limit the demeshing movement of the nut 21. The armature 3 is normally held decentred relative to the field windings 2 by a spring 37 in a cup 38, the latter supporting the spring-loaded plunger 42. Upon axial movement of the armature resulting from energization of the starting motor and causing initial engagement of the pinion and gear 9, the plunger engages an annular groove 41 and maintains the armature in proper relationship with the field against the compression of the spring 37 until the armature attains sufficient speed to enable the plunger 42 to be centrifugally withdrawn. The complete engagement of the pinion and engine gear is effected in the usual manner by the nut and screwshaft.
