Title: Improvements in electric resistance welding
IPC: B23K11/00
Filed: 1958-02-20
Abstract: 820,695. Welding by pressure. ROBOTRON CORPORATION. Feb. 20, 1958 [May 20, 1957], No. 5548/58. Class 83 (4). In electric resistance welding the welding electrodes are pressed against the work, the timing operation of two separate timing means is simultaneously initiated and electrical energy is supplied from one of the timing means at the end of the time interval timed thereby to apply an additional electromagnetic pressing force on one of the electrodes and electrical energy is supplied from the other timing means at the end of the time interval timed thereby to cause flow of welding current through the electrodes. The work parts W1, W2, e.g. of vinyl coated steel or aluminium are arranged between a stationary lower electrode 10 on a base 11 and a movable upper electrode 12 connected to a piston-rod 13 of an hydraulic cylinder 14 and to an arm 16 on an armature 17 hinged at 19 to a U-shaped electromagnet 18 on base 11. The secondary 23 of a transformer 24 is connected to the electrodes and a winding 26 about one leg of the magnet is connected to the secondary 29 of a transformer 31. The primary windings 32, 34 are connected through time control means 33, 36 respectively to supply the electrodes and magnet winding from sources S1, S2. The control means are connected to a supply S3 through a control means 38 for simultaneously initiating the operation of the means 33, 36 and for controlling the application of hydraulic pressure by a solenoid valve 39. The control firstly causes the cylinder 14 to move the electrodes into contact with the work and then causes operation of control means 36, 33 which energize transformers 31, 24, one after the other during the same half cycle of supply current. The pressure on the work increases due to the pull of the magnet on the armature 17 and then the welding current of 5-25 millisecs. duration is caused to flow. The hydraulic means 14 may be replaced by air or mechanical means or the magnetic means may be used alone.

Title: Honing tools
IPC: B24B33/08
Filed: 1976-02-13
Abstract: 1537085 Honing tools NAGEL MACHINENUND WERKZEUGFABRIK GmbH 13 Feb 1976 [14 Feb 1975] 05679/76 Heading B3D A honing tool comprises a tool body 12 on which honing bodies 25 are mounted and movable relative to the body by an expander body 32 which acts upon the honing bodies to effectively expand the tool when the expander body is rotated relative to the tool body. The upper end of the tool body is connectible to the spindle of a honing machine which also has an axially movable expanding mechanism connectible to the end 15 of a transmission shaft 16 located in a bore 17 of the tool body. A pin 18 on the shaft engages an inclined slot 19 in the tool body so that axial movement of the shaft is converted into a rotary movement which, by a tongue and slot connection 22, 23, is transmitted to the shaft 24 of the expander body 32. The shaft 24 and expander body 32 are held against axial movement and some other connection, such as a claw coupling, splines or slot guide, may replace the tongue and slot connection 22, 23. The tool body 12 has radial slots 27 in which the honing bodies are movable radially outwardly by rotation of the expander body 32 against the force of springs 31. Each honing body consists of grinding material 28 on a carrier 29 having a flat face 30 engageable by an edge 34 of the expander body which, in the case of a tool having four honing bodies, is of square crosssection, rotation of the expander body thus causing radially outward movement of the honing bodies. The expander body may be slightly larger at its outer end than its upper end when the honing tool is to be used for honing blind bores. In another embodiment, the honing tool has two honing bodies which are moved radially outwardly by an expander body in the form of a round rod having opposed flats engaging the honing bodies (Fig. 4, not shown). In a further embodiment, the honing tool has a pair of preliminary honing bodies 45, Fig. 6, and a pair of finish honing bodies 55, and the expander body 32b is rotatable in one direction from a neutral position so that edges 34b cause radially outward movement of the preliminary honing bodies 45 and in the opposite direction so that the edges 34b cause radially outward movement of the finish honing bodies 55. The other edges of the expander body are formed as curves 46 for supporting the retracted honing bodies not in operation. In a similar embodiment (Fig. 7, not shown) the expander body is in the form of a rectangular bar and the honing bodies which are not operative are supported by a cylindrical section fitted to the bar.

Filed: 1954-03-04
Abstract: Titanium tetrachloride may be produced by chlorinating, at low temperatures with a minimum of added carbon, a highly reduced titaniferous slag consisting of the oxides and oxycarbide of titanium which is produced by smelting a mixture of 100 parts titaniferous iron ore and 17-25 parts carbonaceous reducing agent at a temperature of 1700-2300 DEG C. in an electric arc furnace, periodically adding more mixture, cooling and solidifying the furnace contents and separating the resultant solidified globules of metallic iron from the highly reduced titaniferous slag.ALSO:Iron is removed from titaniferous iron ore, to leave a highly reduced titaniferous slag consisting of the oxides and oxy-carbide of titanium, by smelting a mixture of 100 parts titaniferous iron ore and 17-25 parts carbonaceous reducing agent at a temperature of 1700 DEG -2300 DEG C. in an electric are furnace, periodically adding more mixture, cooling and solidifying the furnace contents and separating the resultant solidified globules of metallic iron from the highly reduced titaniferous slag.  In the embodiment described, a mixture of ilmenite and coke in the appropriate proportions is charged into an alternating current are furnace (see Group XI) and the furnace is heated to 1800 DEG C. by an arc struck between an upper electrode and the charge.  Successive charges of feed material are added to the furnace when the iron of the preceding charge has coalesced in globules.  When the furnace is full the power is cut off and the furnace allowed to cool, a small amount of coke being added to prevent reoxidisation of the slag.  The fused central core of highly reduced slag and iron globules is removed from the remaining partially reduced feed material in the furnace and is broken up and the iron globules separated, any remaining iron in the slag being removed by leaching and/or magnetic separation.  The partially reduced feed material may be used as a constituent of the feed mixture or as a thermal insulation material for the furnace crucible and the iron globules, which are stated to have a composition similar to that of pig iron, may be collected and utilized.
