Patent GB-402173-A (GB)
Title: Improvements in or relating to the production of fabricated structures
IPC: E04F13/04
Filed: 1932-06-27
Abstract: 402,173. Lathing. SOUTHERN J. H., 41, Newcomen Terrace, Redcar, Yorkshire. June 27, 1932, No. 18119. [Class 20 (iv).] Lathing consists of a metal mesh 2, Figs. 3 and 6, and a sheet 5 of backing material such as paper which is slitted at interval and deflected through the mesh to form ribs 7, in which are inserted rigid members 8 between the ribs and mesh. The machine for making the lathing comprises means for slitting and deflecting the backing, inserting the bars 8, and cutting off required lengths of bars. In the construction shown in Fig. 7, the backing 5 is drawn from a roll 106 and passes with the mesh 2 over a roller 109, thence between a die 18 and slitting knives 12, Fig. 13, then between the corrugating dies 22 and bar 24, Fig. 15, in which position a bar 8 is threaded through the corrugation by mechanism driven intermittently, and the surplus length is cut off. The knives 12 are carried by a beam 10 reciprocated vertically by levers 15, links 49, a yoke 28 and a cam 38, Fig. 12. The corrugating is effected by three bars 23, 24, 25 in yokes 26, 28, 27, respectively. The yokes are operated by cams 36, 37, 38 timed so that the bar 25 is first raised to grip the mesh and backing, then the bar 24 is raised to corrugate the backing, then the bar 23 is raised to grip the material and the bar 24 lowered slightly and finally, for threading the bar 8, all three bars 23, 24, 25, are lowered together, this cycle being repeated at each revolution of the shaft 39. The bar 8 is fed across the fabric by the apparatus 40, comprising pairs of rollers 41, 43 and feed rollers 42. The intermittent drive for the feed rollers may be that described in Specification 393,346, [Group XXIV]. The bar 8 is passed through a barrel 44 and the excess is sheared off by a cutter 45. The fabric is then drawn forward a distance equal to the spacing of the ribs by claws 63, Fig. 8, on a crosshead 56 which is driven by a lever 57 and cam 61. Lengths of completed fabric may be cut off by a fixed blade 72 and a movable blade 74 operated by levers 77, 79 and cams 82, 83. The cam shafts 50, 84, 85 are driven by chain gearing from the main shaft 68 and the controlling clutch member is operated by a lever and a cam, the latter loose on the shaft 84 and chain-driven.

Title: Method and apparatus for the manufacture of hollow bodies from thermoplastic material
IPC: B29C49/64
Filed: 1961-05-18
Abstract: 962,260. Moulding hollow articles. R. HAGEN, [trading as KAUTEX - WERK REINALD HAGEN]. May 18, 1961 [May 18, 1960], No. 18188/61. Heading B5A. In the production of hollow articles from thermoplastic material in the form of an extruded tube which is detached from the extrusion nozzle by a gripper device, said tube is introduced into a hollow mould wherein it is expanded and shaped by blowing, the end of the tube being located over a mandrel, the shaped article being removed with the mandrel from the mould after initial cooling to a degree of rendering the article self-sustaining and finally cooled and solidified externally of the mould. Two or more mandrels may be arranged to pass successively through a single mould. In an embodiment, Fig. 1a, an intermittently rotatable, horizontal table 17 carries from equally spaced mandrels 13, 14, 15, 16 constructed as blowing nozzles, to pass successively beneath an extruder nozzle 19 to receive a tube 20 of thermoplastic material therefrom. A gripper 21 is associated with each mandrel and serves to separate the tube 20 from the extruder nozzle 19 and to support it during a 90 degrees rotation of the table 17, whereby the tube is carried on the mandrel to the position of mandrel 13 between the separated halves of the mould 12. After shaping of the tube 20 by closing the mould 12 and introducing compressed air through the mandrel 13 the table 17 is further advanced in successive steps of 90 degrees during which advance the shaped article, e.g. a bottle, is further cooled externally of the mould, the finally cooled article being removed from the mandrel 14. A superatmospheric pressure may be maintained within the article during cooling. In a modification the number of equally spaced mandrels is increased and a single gripper 21 is arranged to reciprocate between the mould and the extruder. In another embodiment, Fig. 2a, a pair of blowing mandrels 27, 28 are arranged to reciprocate linearly together on a rail 30 to alternately receive a tube 31 from a pair of extruder heads 25, 24, the tube 31 being supported by grippers 33, 32 arranged to move with the mandrels 27, 28 to and from the two part mould 26. Alternatively, a single extruder is associated with a plurality of linearly arranged mandrels which advance successively through the mould, their return being carried out by a single movement. In another modification, the mould 26 is spaced beneath the extruder heads 24, 25 and the mandrels 27, 28 are additionally arranged to move vertically with the grippers 33, 32 to collect the tube 31. In a further embodiment, Fig. 3a, the extruded tube 37 is carried vertically downwardly by grippers 42 to the two part mould 35. Alternatively, the mould itself may be moved vertically to and from the extruder head.

Title: Improvements in dynamo field producing structures
IPC: H02K21/24
Filed: 1966-04-26
Abstract: 1,146,988. Machines with permanent magnets; core constructions. GARRETT CORP. 26 April, 1966 [3 June, 1965], No. 18207/66. Heading H2A. A generator field-producing structure for a planar air gap machine comprises primary permanent-magnet flux-producing means magnetized in a direction normal to the air gap working surface to provide alternate axial north and south poles around the axis, and secondary permanent magnet flux-producing means magnetised and arranged generally crosswise of the primary permanent magnet means in flux-additive series relation thereto, the secondary means opposing leakage flux normally associated with the primary means. In Figs. 1, 2 and 7 to 11 (not shown), secondary circumferentially-magnetized magnets extend between axially-magnetized primary magnets forming part of a disc-shaped rotor. The secondary magnets may have a rectangular cross-section so that the width is uniform from the face to the interior, or they may have a triangular or stepped-triangular cross-section so that the width is progressively reduced in that direction. The ring of primary and secondary magnets may be located concentrically between two further continuous rings of permanent magnet material magnetized radially to provide alternate N-S and S-N regions. The rotor may be faced by polepieces separated by portions of very high electrical conductivity, and be backed by a flux-return member. Material of high electrical conductivity may be interposed between each secondary magnet and the flux-return member to prevent shunting. In Figs. 5, 6 and 12 (not shown), the circumferentially-interposed secondary magnets are omitted, the primary magnets abutting each other, and the concentric rings of permanent magnet material, mentioned above, constituting the secondary magnets. The flux-return member has an outer (and may have an inner) flange directed towards the air gap to enclose the magnet assembly and counteract centrifugal effects. Figs. 13,to 17 (not shown), are modifications of the Fig. 5, 6 embodiment where the primary magnets and concentric rings are replaced by a single ring of permanent magnet material. At any one location the radially-central portion is magnetized in a direction normal to the air gap, while the radiallyremote portions are cross-magnetized on a radial-axial curve.

IPC: C03B15/02
Filed: 1966-04-27
Abstract: 1,141,208. Treating surfaces of glass sheets. GLAVERBEL. 27 April, 1966 [6 May, 1965], No. 18531/66. Heading C1M. In a process for the production of flat glass, especially by drawing, molten glass at a surface region of a molten glass bath is fed to a glass forming unit and is traversed by an electric field extending between the underlying molten glass and the atmosphere in contact with the bath. In the vertical draw " Pittsburgh " process positive electrodes 10 are affixed to the undersurfaces of the L-shaped shields 3 and negative electrodes 11 are affixed to the upper surface of the draw bar 9. In this way either the alkali ions in the glass surface are caused to migrate to lower depths or other ions fed through tubes 13 into the atmosphere in the electric field above the glass surface are caused to migrate into the glass surface. Thus the surface properties are altered in order to give better weather resistance, better optical properties or a form of chemical tempering. Similarly in the " Libbey-Owens " process the floor (45) of the drawing bath is formed as the negative electrode and the foot of the wall (23) between the chamber and the melting zone is formed on the positive electrode (44). The polarities may be reversed if desired. Further by having more than one lower electrode and/or more than one upper electrode, an electric field which differs in strength or direction from one zone to another within the area traversed by the field can be established by maintaining different upper and/or different lower electrodes at different potentials or by varying the spacing between upper and lower electrodes from one zone to another. This will permit different modifications of the properties of the glass. In the case where an ionized substance is fed into the atmosphere that substance is selected from the group, calcium, magnesium, barium, lead, tin, iron, manganese, nickel, cobalt, copper, selenium and alkali metals.

Title: Method of manufacturing fertilisers from calcium nitrate and urea
IPC: C05C9/00
Filed: 1955-06-27
Abstract: Calcium nitrate, separated from nitric acid solutions of natural phosphates by cooling and centrifuging, and still impregnated with nitric and phosphoric acids is treated with urea to neutralize the free acid, thereby forming urea phosphate and nitrate, and to combine with the calcium nitrate in substitution for water of crystallization, to form the compound Ca(NO3)2.4CO(NH2)2. Specifications 246,377, 339,500, [both in Class III], 359,680 and 685,193, [both in Group III], are referred to.ALSO:Calcium nitrate, impregnated with nitric acid and with at least 0,4 per cent. by weight of phosphoric acid, which has been separated from the solution resulting from attacking natural phosphate with nitric acid, is treated with urea to form a neutral fertiliser containing urea nitrate and urea phosphate.  If excess urea is employed it combines with the calcium nitrate in substitution for the water of crystallisation in the form of Ca (NO3)2. 4 CO-(NH2)2. Neutralisation of the free acid of the calcium nitrate may be effected in part by alumino-calcium phosphates and the free phosphoric acid content may be deliberately increased and then neutralised, in part, with calcium or ammonium compounds prior to incorporating urea. According to examples (1) crystalline calcium nitrate obtained by cooling and centrifuging a solution obtained by attacking phosphate with nitric acid was melted at 60 DEG C. and an equal weight of urea added.  After concentrating at 100 DEG C. a fertiliser containing 33,2 per cent. nitrogen resulted.  Calcium carbonate may be added.  (IV) Calcium nitrate was treated with urea as in (I) and calcined alumino-calcium phosphate was added, together with potassium sulphate.  The resulting paste was granulated with an equal weight of recycled dried dust from preceding operations. Specifications 246,377, 339,500 [both in Class 111], 359,680 and 685,193 [both in Group III] are referred to.
