Title: Improvements in automobile vehicles
IPC: B60L50/15
Filed: 1924-05-02
Abstract: 241,965. Lanchester, F. W. May 2, 1924. Exciting; pole-pieces, cores, yokes, and carcass structures.-A machine having field magnets upon which series and shunt exciting coils are spaced widely apart and in which the intervening spaces permit or promote magnetic leakage, is combined with a petrol or other engine driving a vehicle so as to start the same in either direction and to assist the engine or charge a battery during forward running. The shunt and series windings are opposed whilst charging, the magnetic leakage limiting the current produced. The machine is series excited for starting but is additively compounded when assisting the engine. Preferably the drive is direct and an independent battery charging set of small capacity may be installed. A magnetic or dog clutch may be used so that the engine may be run independently of the car for inspection, test or battery charging. Fig. 1 shows the fly-wheel of an internal-combustion engine 1 constructed as a Gramme ring A<1>, its windings being connected by truly radial connectors to a commutator 3. The field magnet cores B<1> are mounted one on each side and carry shunt coils B<3> and series coils B<2> arranged as shown, the portions of the cores between the coils being bolted to extensions of the base chamber of the engine 1 and being shaped according to the degree of magnetic leakage desired. A portion of the shunt field flux may be shortcircuited by an iron bar or a by-pass external to the winding. The brushes in the four-pole machine described are arranged as in Fig. 2, the pairs lying between the magnet cores being connected together to short-circuit the subtended idle portion of the armature and reduce the total resistance. A six-pole machine similarly constructed and another with a ring field core and six salient poles are illustrated in the Specification. Carbon brushes are employed or a combination or carbon and high conductivity compositions or copper brushes. A controller having four positions, viz. : " reverse," " ahead," " charge " and " off " is shown diagrammatically in Figs. 6, 7, and 8, which respectively illustrate the first three steps.

Title: Improvements in or relating to the manufacture of ferrous wire
IPC: B21C37/04
Filed: 1943-07-08
Abstract: 566,263. Drawing wire. WARBURTON, J. W. July 8, 1943, No. 11102. [Classes 83 (ii) and 83 (iv)] [Also in Group III] In the manufacture of ferrous wire, after descaling, the wire is treated with an alkaline liquid and with one containing an oily or gelatinous substance. Starting from a cast billet about 12 inches diameter and from about 2 to 3 feet long, this is hot-rolled to a diameter of from 0.212 to 0.22 inches. The coil is descaled by steeping it in hydrochloric or sulphuric acid for from 20 to 40 minutes. After washing the wire is immersed in or treated with an alkaline liquid that does not leave an undesirable residue upon the surface of the wire after neutralizing the acid. The liquid may be used from room temperature to boiling point. The alkaline liquid may be sodium metasilicate, tribasic sodium phosphate, or borax. The oily substance may be sulphated castor oil, sulphated linseed oil, sulphated fish oils or a sulphated fatty alcohol. The preferred substance is a mixture of sodium metasilicate and sulphated castor oil. The sulphated castor oil reduces the surface tension, enabling the liquid to penetrate the coil of wire freely and to drain easily. Some of the oil is saponified by the alkali resulting in a deposition of soap on the wire. The protective coating retains its properties over a considerable period and facilitates the adhesion of powdered soap from the soap box during drawing. The liquid may be made up from 100 gallons water, 56 lbs. sodium metasilicate and three gallons of 50 per cent or 70 per cent sulphated castor oil. These proportions may be varied, in particular the amount of silicate may be reduced particularly if a preliminary immersion in sodium carbonate solution is given. When the sodium phosphate is employed, a rust-resisting coating of iron phosphate is formed.

Patent GB-728656-A (GB)
Title: Preparation of cyanoalkenes
Filed: 1951-05-16
Abstract: Mono-cyanoalkenes are prepared by the oxidation of the corresponding mono-cyanoalkanes, containing at least 3 carbon atoms, in the vapour phase with molecular oxygen present in an amount of from 0.1 to 2 mols. per mol. of nitrile.  Oxidation is effected, in general, at about 250-900 DEG  C. or higher, if desired in the presence of an oxidation catalyst effective in vapour phase oxidation.  Oxidation inhibitors may also be present.  The oxygen may be used alone or with an inert diluent such as nitrogen or carbon dioxide, and may be introduced at a plurality of points along the reaction vessel.  The oxidation product is condensed and distilled to remove first the water formed and then the cyano-alkene; the residue is recycled to the oxidation stage with additional cyano-alkane feed.  Suitable oxidation catalysts are iodine, hydrogen bromide, diphenylamine, metals of Group IB and their oxides, metals of Groups II to VII and their oxides, including compounds giving rise to these oxides under the reaction conditions, sulphates, silicates and phosphates, alone or supported on various carriers; silica-gel and boric oxide-silica gel.  Specified oxidation initiators are phenols, benzene, naphthalene, anthracene, methane, higher alkanes, ethers, aldehydes, ketones, nitro compounds, oxides of nitrogen, sulphur, sulphur oxides, hydrogen cyanide and peroxy compounds.  In typical examples illustrating the conversion of propionitrile and isobutyronitrile to acrylonitrile and methacrylonitrile respectively; (2) propionitrile containing 2 per cent phenol is passed with 0.49 mol. of oxygen through a quartz tube at 535 DEG  C.; similarly, (6) propionitrile and air are passed at 260 DEG  C. through a glass tube containing silica gel granules impregnated with a mixture of cadmium and uranium nitrates; (7) propionitrile vapour and air are injected into the bottom of a boiling bed of silica gel powder impregnated with uranium nitrate and maintained at 448-497 DEG  C.; (13) isobutyronitrile containing 2 per cent iodine is passed with air through a quartz tube at 630 DEG  C.  The propionitrile and isobutyronitrile may also be introduced in the form of their corresponding amides, the cyano alkanes being formed in situ.  The oxidation of propionitrile is stated to yield trace amounts of acetonitrile, isobutyronitrile and methacrylonitrile.ALSO:A catalyst for use in the oxidation of propionitrile to acrylonitrile (see Group III) is prepared by washing silica gel granules with dilute nitric and hydrochloric acids, igniting the washed granules, then impregnating the granules by introducing thereto an aqueous solution of cadmium and uranyl nitrates and applying a vacuum and finally drying.  Another catalyst is prepared in like manner from silica gel powder, aqueous uranyl nitrate only being used in the impregnation.

Title: Oscillatory metal cutting machine for producing arcuate forms
IPC: B23Q5/40
Filed: 1927-04-30
Abstract: 283,389. Bonom, A. April 30, 1927. Shaping curved surfaces; tools.-In a metalshaping machine for cutting arcuate forms, particularly for cutting the blade-receiving slots in the end rings of radial flow steam turbines, an annular tool provided with a cutting projection is oscillated through the required arc by crank mechanism and is fed to the required depth into the work which is indexed between successive operations. The frame 16 carries a standard 17 integral with an arm 18 above which the driving shaft 21 is mounted. The vertical tool-spindle 26 is threaded to receive a socket 33 into which is screwed the annular tool 37 having a cutting projection 35. The tool is locked in position by a flanged ring 32. A pin 30 located centrally in the holder may be moved down by means of a projecting handle working in a slot in the toolspindle in order to locate the tool accurately for a slotting operation. A modified form of toolholder is shown in Fig. 5. The shaft 21 carries an adjustable crank-disc 77 connected by a rod 72 to a gear segment 69 engaging a gear 68 on the tool spindle which thus receives an oscillatory movement of the required amplitude. The tool-spindle is positioned vertically by a collar 45 having a ball bearing connection with a nut 46 engaging a rotatable internally-threaded sleeve 48 which is secured against axial movement by upper and lower ball bearings 52, 49 respectively. The nut 46 is held against rotation by rods 58 held between a head 59 and a fixed lower member 60. The upper part of the sleeve carries a ratchet-wheel 53 and a bevel gear 54, the latter being rotated from a hand wheel 56a for manual adjustment of the tool spindle. In order to apply automatic depth feed to the tool, the shaft 21 carries an adjustable striker 23a engaging an arm 39 of a rock-shaft 38 a finger 41 on which is normally engaged by a spring 40 with an adjustable stop 42 which determines the swing of the finger 41. The latter is connected to an arm carrying a pawl engaging the ratchet wheel 53, the pawl moving idly over the ratchet during the positive movement of the rock shaft and being instantaneously shifted by the spring 40 to effect the feed on the return stroke of the tool. The work bed comprises a slide 80 which is adjustable by a screw spindle 84. A turntable 85 supported on roller bearing on a support 15 is keyed to a spindle 87 which may be operated through bevel gearing from the shaft 91 of dividing mechanism. The blank, secured by a nut to an extension of the spindle 87, consists of a circular plate 93 previously formed with annular ribs 95. Curvilinear grooves are cut in these ribs after which the ribbed portions are removed by successive cuts to form the rings separating the blades of a turbine. For spacing the slots the turntable is intermittently rotated by the dividing mechanism. The machine may also be adapted for cutting the dovetail ends of the rotor blades for fitting in the slotted rings.
