Title: Method of and apparatus for manufacturing fibrous cement sheets
IPC: B28B1/42
Filed: 1969-06-24
Abstract: 1,263,486. Making fibrous cement sheets. F. L. SMIDTH & CO. A.S. 24 June, 1969 [24 June, 1968], No. 31789/69. Heading B5A. Fibrous cement sheets are made by rolling up wet strips from conveyer 1 on roller 4, cutting the rolled up web parallel with the axis of the roller when the web reaches the desired thickness, and unwinding the cut web 22 on to a conveyer 23. The speed of the surface of conveyor 23 is not greater than 1À05 and preferably is 1À02-1À04 times the peripheral speed of the roller 4 when the first 0À5-1À5 m. of the web is fed on to it, and from 1À00-0À97 .times during the remainder of the transfer period.. The speed change is preferably not more than 5%. As shown, asbestos cement strip which has been formed on felt conveyer 1 is transferred to roller 4 which is driven by contact with conveyer 1 and builds up a web as the roller rotates. When the web has the correct thickness, bar 7 is depressed and, as the roller rotates lever 11 contacts cam roller 10 and forces cutter blade 13 through the web in the position shown. The cut web falls on to conveyer 23 which is moving at its faster speed and after the web has been advanced between 0À5 and 1À5 m. by the conveyer, the web contacts a lever which slows the conveyer 23 to its lower speed.

Abstract: 835,820. Glass manufacture. KURZ, F. W. A. Oct. 11, 1957, No. 31798/57. Class 56. Articles of alkali-lime-silicate glass are treated during their manufacture while within the temperature range of 1000‹ to 450‹C. and in the absence of moisture, to the action of vapours of compounds which are volatile at the treatment temperature and which are capable of modifying the composition of the article by forming glass components increasing the chemical resistance of the glass, the vapours being kept in motion so that they contact the entire surface of the article or at least the entire inner or outer surface of a hollow article, whereby in a superficial layer the composition of the glass is modified to increase the resistance of the glass. The compounds used may be halides or carbonyls of Al, Zn, Zr, Cr, Mo, W, Co, Ni, B, Ma or Si. The articles may also be treated with gaseous substances which form compounds with the alkali in the surface layer, such as SO 2  with O 2 , SO 3  or HC1. The treatment is preferably carried out at decreasing temperatures until there is practically no alkali diffusion. Brief superficial heating from temperatures near 450‹C. to about 600‹-1000‹C. may also be used, thus increasing the depth of the layer. Used in the treatment of glass fibres, plate glass, tubes, ampoules, containers, tiles, blocks, insulators and other articles.

Abstract: 341,887. Sheathing wires, rods, or tubes with metal. METALLGES. .AKT.-GES., 45, Bockenheimer Anlage, Frankfort-on-Main, Germany. Oct. 19, 1929, No. 31854. Addition to 304,736, [Class 83 (iv), Metals, Working]. [Classes 83 (ii) and 83 (iv).] Wire; welding ; drawing.-In making elongated metal bodies consisting of a core and metal sheath having one or more longitudinally welded joints, by pressing one or more strips over the core, as described in the parent Specification with reference to sheathed wire cores, the strips are narrower than the periphery of the core so as to leave one or more gaps between adjacent edges, the gap being closed by flow of metal in the direction of the joint during welding. The strip may be thickened locally at one or more points 5, Fig. 2. Sheathed wires, cables, rods or tubes may thus be made. An aluminium strip 2 may be drawn from a furnace 20 heated to welding temperature through a die 4 to bend it over an iron core 1 into the form shown in Fig. 3. Welding may then be performed by rolls 6 with circular grooves which cause the metal to flow towards the joint to effect the weld. The burr may then be removed by rolls 7 and the sheath finally smoothed by a die 9. Guide rolls may be provided on both sides of the die 4. In another form, the sheath may be bent and then welded on a hollow mandrel through which the core is passed, the sheath being subsequently pressed on the core and the joint smoothed by rolling or drawing, after first cooling if necessary. Welding may be effected also by drawing or hammering. For electrical purposes the sheath may consist of aluminium, copper, iron, lead or other metal or alloy. For overhead conductors the core may consist of iron wire or of a cable of steel or other metals or alloys of high mechanical strength such as normalizable aluminium alloys and the sheath of aluminium. A conductor with a sheath of a normalizable aluminium alloy may be subjected to a subsequent heat treatment to effect the normalizing. If the core is of such an alloy this may be normalized during welding. High tension cables may consist of a core of copper wires or cables and a sheath of aluminium. Bands may also be made by deforming the composite wire.
