Title: Method and apparatus for forming metal ring blanks
Inventor: STERN LIONEL
IPC: B21F37/02
Filed: 1969-09-10
Abstract: 1277045 Making rings; angular bending; shearing A T RICHARDSON & SONS PTY Ltd 10 Sept 1969 [26 Sept 1968] 44593/69 Index F2T 37E1R A method of making a metal ring comprises cold-pressing a round wire or bar into a barrelshaped cross-section, having two opposed flat sides linked by convex sides, forming the wire or bar into a ring and cold-pressing at least three sides of the cross-section of the ring to produce the ring. If the internal diameter of the ring is critical the ring is welded then pressed by platens 6 and 7 after pushing an oversize mandrel 8 through the ring, Fig. 3 If both internal and external diameters are critical a modified platen 7a is used, Fig. 5. For producing split piston rings the formed ring is not welded but fitted into a sleeve 13 and pressed by platens 6 and 7, Fig. 6. If both internal and external diameters are critical then one of the platens 6 or 7 may have a surface (11a), Fig.7 (not shown), for pressing the internal diameter whilst the outer diameter is formed by sleeve 13. An apparatus for producing the rings comprises two pressing rolls 14, 15, of which at least one, preferably 14, is driven, which form a round wire or bar 2, which is guided to the rolls by means 15, into a barrel-shapedcrosssection 3, a means for forming the flattened wire or bar 3 into a ring and a shear means 21 operated through a linkage 22 for shearing off a predetermined length to form a ring. The means for forming the ring may be a roller 17 or a shoe 18 both of which are adjustable to produce rings of any desired diameter.

Filed: 1968-09-20
Abstract: 1,244,194. Purifying nickel salts. RESEARCH HOLLAND N.V. 20 Sept., 1968 [22 Sept., 1967], No. 44784/68. Heading C1A. [Also in Division C7] Nickel salts or nickel salt solutions contaminated with copper and zinc are purified by treating a solution of the nickel salt at a pH #4À0 with a sulphide, preferably H 2 S or an ammonium, alkali or alkaline earth metal sulphide or polysulphide, excess sulphide being removed by oxidation or precipitation. Specified nickel salts are the sulphate, chloride, sulphamate and fluoborate. The excess sulphide may be oxidized with a hydroperoxide or KMnO 4 , preferably after the solution has been filtered in order to remove contaminants and thus to prevent formation of soluble ZnSO 4 . The excess sulphide may be precipitated by the addition of a metal ion of which the sulphide has a smaller solubility product than NiS but is preferably removed by raising the pH to 5À0-5À5, thereby precipitating the excess sulphide as NiS. Active carbon is preferably added to the solution when the excess sulphide has been removed. Nickel salts purified in this manner are particularly useful in electrolytic processes (see Division C7).

The binder liquor may be an aqueous solution of sodium silicate, a cement slurry, bitumin, or as suspension or dispersion of phenol formaldehyde resin. In order to ensure that the binder remains liquid until the streams mix and are laid upon the receiving surface heat may be supplied to the binder and/or to the gas stream carrying the fibres. Particulate material, viz graphite, silicious materials, cork granules, PTFE particles and/or metal powders may be incorporated in the felt by addition to the stream of fibres and/or liquid binder or by deposition onto the laid impregnated fibres, preferably between successive layers of laid fibres.

Abstract: 1,124,336. Welding by pressure. SOC. ANON. DES USINES CHAUSSON. 4 Nov., 1965 [26 Jan., 1965], No. 46857/65. Heading B3R.  In resistance welding oxidized parts between a pair of electrodes, welding current is supplied to one electrode, which is pivotally mounted, by a U-shaped flexible conductor and the forces exerted on the conductor when current is passed therethrough cause the legs of the U to be relatively moved and the electrode to be displaced about its pivotal axis. A portable welding device comprises an L-shaped lower electrode 2, Fig. 1, slidable in a support 1 on which is pivotably mounted an upper electrode 4. Current is supplied from a coaxial cable 3 one conductor being connected to the electrode 2 and the other conductor to an inverted U- shaped flexible braid 6 between the cable and the electrode 4. The pivot pin 5 is anchored at one end to provide a torsion bar. When the electrodes are placed on the work, e.g. oxide coated light metal sheet 7 and current supplied the movement of the arms of the U-shaped braid causes the electrode 4 to slide on the upper sheet and it is stated that oxide layers are broken. In a fixed machine each electrode is similar to the electrode 4 of the first embodiment. In another embodiment one of the electrodes, 4, Fig. 4, is mounted to rotate in its support 13 and a U-shaped conductor 6 is arranged to cause pivotal movement of the electrode about its axis. Both electrodes may be so mounted. At least one of the electrodes may be connected to an ultrasonic generator to commence breaking up oxide films before the electrodes are supplied with current. Several pulses of current may be passed through the electrodes before the welding current proper is supplied.
