Title: Process for producing amino-oxy compounds of the aromatic series by electrolysis
IPC: C25B3/25
Filed: 1925-12-29
Abstract: 254,204. Potts, H. E., (Chemische Fabrik Gr³nau Landshoff & Meyer Akt.-Ges.). Dec. 29, 1925. Aromatic amino-oxy compounds, obtaining. - In the electrolytic reduction of aromatic nitro compounds in acid solution using electrodes of base metal so as to introduce an hydroxyl group while reducing the nitro group, the nitro compound is added gradually to the catholyte, excess of the nitro compound in the catholyte being avoided as far as possible. The reduction may be carried out in the presence of colloidal substances or substances forming colloids. Current densities greater than 6 amps per sq. dcm may be employed. In an example, a copper cathode is enclosed within a diaphragm chamber containing sulphuric acid and a solution of glue, the diaphragm chamber being itself enclosed in a lead vessel acting as anode containing sulphuric acid of density 30 BÚ. The voltage is 3 to 3.5, the current density 15 amps per sq, dcm, aud the temperature 80-90 C. The catholyte is stirred energetically and nitro-benzol is slowly added. The electrolysis is preferably carried on for a short time after all the nitro-benzol has been added. The excess and combined sulphuric acid is neutralized by milk of lime or prepared chalk, aniline is driven off by steam distillation, and the chalk paste is filtered off, para-aminophenol being then crystallized out from the hot solution. 4 kgm of para-aminophenol may be obtained from 7 kgm of nitrobenzol.

Title: Induction heating
IPC: H05B6/38
Filed: 1956-11-01
Abstract: 816,011. Induction heating. UNITED AIRCRAFT CORPORATION. Nov. 1, 1956 [Nov. 17, 1955], No. 33356/56. Class 39(3) A heating head for an induction hardening machine comprises a primary fullturn conductor inductively connected to a second conductor constituted b ya plurality of radially movable segments which can be positioned to induce a current in an internal circumferential groove of a tubular work piece, e.g. the ball races of an aircraft propeller hub 26. As shown, a heating head comprises a metal sleeve 38 mounted on the pedestal 12 of a rardening machine and an insulating block 44 which has guides 43, 45, Fig. 3, for the supports of four second conductor segments 48 and 46 and a recess 52 for the primary conductor 50. A metal sleeve 40 secures the block 44 to the sleeve 38 and clamps the conductor 50, together with insulating rings 54 and 56, a shortening ring 60, e.g. of copper, an insulating ring 62 and an insulating sleeve 64, between the block 44 and a shelf 66. An insulating cap comprising elements 100 and 102 in which is formed a channel 104 having a plurality of inlets 106 and outlets 108 is secured to the block 44 and a further protecting metal cover 116 is provided. The primary conductor 50 is connected to an A.C. supply by bus-bars 68 and 70 (Fig. 1, not shown). The segments 46 and 48 are supported in slides 76 and 78 and are linked to nuts 80 and 90 so that they may be retracted or extended, in which latter position the segments 46 are close to but spaced and insulated from segments 48. The shorting ring 60 prevents overheating of the lands between adjacent rgooves. Conductors 50, 46 and 48, and 60 together with bus-bars 68 and 70 are liquid cooled. In their extended position (Fig. 4, not shown) the second conductor segments mate with but are separated from the conductor 50 and their shaped outer ends are positioned close to but spaced from the bottom of the grooves to be heated. In operation the primary conductor induces eddy currents in secondary segments which in turn induce a circumferential current in the bottom of the groove, thus heating it. Air from an inlet pipe 114 is discharged from the outlets 106 on to the heated groove to coo and harden it.

Abstract: 475,838. Sparking plugs. CARING- TON, C. M., POSTLETHWAITE, A. E., and K.L.G. SPARKING PLUGS, Ltd. Dec. 5, 1936, No. 33427. [Class 7 (iv)] Fine wire terminals, of the kind described in Specification 448,913, are clamped in position. Grooves 11, slightly smaller in diameter than the wire, are formed in a ring 10 which is secured against a shoulder 22 by rolling over the end 23 of the casing 21. The wire terminals 17, having been positioned by a central mandrel, are forced into the groove by an annular tool. As the ring 10 has a bevelled edge 12, one end of the wire remains relatively undeformed, thus preventing axial movement, which may however be prevented by an enlargement in any part of the groove. The wire projects slightly above the face of the ring 10 so that it may be tightly clamped against the shoulder 22. The projecting end of the wire is shorn off. The metal for the wire may be platinum, iridium, or a platinum-iridium alloy.

Abstract: 1358499 Setting wool slivers; false twister KANEBO KK 18 July 1972 [19 July 1971 22 Feb 1972] 33537/72 Headings DID and D1F In order to temporarily decrimp a wool sliver and set said decrimping during the manufacture of a top in a worsted spinning process, the wool sliver is subjected to heat and moisture, heated under tension whilst being false twisted by first twisting and then untwisting and then dried under a weaker tension and a temperature no higher than the false twisting step. The sliver 1 is fed through steam chamber 5, which raises the moisture content of the sliver to 20 to 30% and the temperature to 70 to 110‹C and then to nipping roller unit 4 in chamber 5' which is heated by steam pipe P and by steam entering between members 3c, 3d. Between rolls 4 and twister 6 the sliver is twisted and between twister 6 and rolls 7 it is untwisted. The rolls 7 are driven at a common circumferential speed in excess of that of rolls 4, thereby drafting the sliver by 20 to 40% between rolls 4 and twister 6 to remove the crimps. The distance between twister 6 and rolls 7 is less than the average fibre length (6-7 cm) to prevent fibre slipping whilst the sliver is untwisted. As shown in Fig. 6 the twister comprises a tube 61 rotated in bearing 63 by driven sprocket 64, the sliver being cranked by passage over ring 62. Preferably the sliver spends at least 30 seconds in the twisting zone and receives 15-40 turns/ metre. Drying occurs in chamber 9 during the passage over heated rolls 8a-8e in the presence of a stream of dry air, the temperature being lower than that of the twisting chamber.
