Title: Improvements relating to the production of glycols
IPC: C07C31/20
Filed: 1930-09-18
Abstract: <PICT:0365589/IV/1> In the continuous production of glycols by reacting upon chlorhydrins with a non-caustic alkali such as sodium carbonate, the reagents are heated under pressure to 105-150 DEG  C. within a series of vessels or columns or a continuous conduit of such shape that at intervals the lower parts form liquid pools and the upper parts serve for the passage of the material in the form of froth. Baffles or packing may be provided in the columns or vessels. In the apparatus shown, the chlorhydrin and sodium carbonate solution are heated and fed to a series of towers, b, b<1>, b<2>, b<3> connected alternately at bottom and top by pipes e, g.

Title: Improvements in or relating to commutators for dynamo-electric machines
IPC: H01R39/32
Filed: 1958-09-01
Abstract: 890,013. Proofing for electric insulation. WATLIFF CO. Ltd., and ARNOLD, W. E. Aug. 21, 1959 [Sept. 1, 1958], No. 28026/58. Addition to 784,717. Class 140. [Also in Group XXII] In the manufacture of a commutator for a dynamoelectric machine the commutator 11 is covered by a stretched mask 21 comprising a film of elastomeric material to prevent the intersegment recesses 16 being filled when the armature windings are impregnated. The impregnation is carried out by immersion of the rotor in a bath of the insulating composition by a dipping or double dipping process or by a vacuum process in which the rotor is vacuum dried, dipped in insulating varnish and placed in a chamber which is then evacuated. Air is re-admitted to the chamber to force the varnish into the windings and the rotor is subsequently baked. Examples of suitable materials for the commutator mask are cured or vulcanized silicone rubbers and polyurethane elastomers since these are free from sulphur and chlorine and do not produce corrosive fumes when heated. Due to the extensibility of these materials one size mask may be used on a number of different diameter commutators. The mask is removed by stripping or machining.

Title: Method and an arrangement for dispersing magnesium in vacuum tubes
IPC: H01J7/18
Filed: 1927-10-24
Abstract: 279,844. Loewe, S. Oct. 26, 1926, [Convention date]. Vacuum tubes.-In producing high vacua in vacuum tubes such as radio amplifiers by dispersing magnesium, the magnesium is arranged movably in the tube and is situated further from the electrodes whilst these are being freed from gas than when the magnesium is dispersed. The anode can thus be strongly heated, for example to a bright yellow heat, by electron bombardment or eddy currents to free it from gas without dispersing the magnesium and the magnesium can then be moved near the anode and dispersed by heating the anode less strongly to red heat, gases not being liberated from the anode during the second heating. The magnesium may be in the form of a perforated disc 7 slidable on a holder 8 on the anode 3, the disc 7 being originally on a hook 9 away from the anode and being moved prior to dispersal to the position 10 against the anode by reversing or shaking the bulb 1, this reversal being easy if the bulb 1 is fused off from the pump before the magnesium is dispersed. In a modification, the magnesium 12 is carried on an angularly movable strip 11 of mica. Prior arrangements are referred to in which a magnesium ring or ribbon 5 is held fixedly on the anode, for example, on a heatconducting nickel strip 6 as in Specification 256,975.

Title: Improvements relating to a process of purifying zinc chloride
IPC: C01G9/04
Filed: 1930-09-24
Abstract: Zinc chloride is freed from lead, lead chloride, or lead oxychloride by melting it in the presence of excess of zinc and continuously circulating portions of the molten salt through an underlying bath comprising metallic lead until the lead &c. has been extracted.  The slag of pure zinc chloride is then removed from the surface of the bath.  The operation may be carried out at 730-760 DEG  F.  The zinc chloride may be that obtained from lead containing zinc as an impurity and obtained for instance in desilverizing lead by the Parke's process, the dezincing step being effected by heating the lead to 650-750 DEG  F. and continuously circulating portions of the molten lead through a chlorinating chamber until the zinc chloride slag floating on the molten metal becomes contaminated with lead chloride.  From the zinc chloride obtained zinc and chlorine may be recovered for further use in the process.ALSO:The zinc is removed from lead which has been de-silverized by the Parke's process by heating the lead to 650-750 DEG  F. and continuously circulating portions of the molten lead through a chlorinating chamber until the zinc chloride slag floating on the molten metal becomes contaminated with lead chloride.  The zinc chloride slag is removed and purified by excess of zinc, and may then be treated to recover zinc and chlorine for re-use in the de-silverizing and de-zincing operations respectively.
