Abstract: A method of cutting corrugated material into a plurality of channel shaped bodies in which the material is conveyed by means of guide members parallel to a path along which the material is conveyed. The path is perpendicular to the channels defined by the corrugations and the walls of the channels are severed while the corrugated material is held by the guide members.

Abstract: This invention relates to a bushing for processing molten glass. The bushing has a bottom wall provided with orifices to deliver downwardly flowing streams of molten glass, side walls and end walls. The bushing is provided with oppositely arranged terminals to receive electrical conductors for heating the bushing. The end walls of the bushing and the terminal means are moulded integrally from rhodium or platinum/rhodium alloy.

Abstract: The disclosed invention pertains to a process for melting glass in which scrap glass fibers containing carbonaceous material to provide a carbon content of 0.4%-0.04% in a batch is combined with batch materials in which the scrap amounts to 5%-25% by the weight of the batch. The batch is melted under oxidizing conditions and the resultant melt is used to form glass fibers.

Abstract: Glass fiber reinforcing members with at least one end anchorage point are formed from glass fiber rovings impregnated with resin and shaped into a ribbon. The ribbon is surrounded before curing at discrete intervals with castings which, after curing, provide areas which can be formed into anchorage areas.

Abstract: This invention is concerned with coating Glass Fibers with size and is also concerned with the provision of an improved size composition for use in carrying out the coating step. We provide an aqueous size composition including a polymer dispersion of cationic character, at least 90% of the polymer being formed from units derived from vinyl acetate. The cationic character of the polymer dispersion is formed during preparation of the polymer dispersion by emulsion polymerization.

Abstract: A process is disclosed for forming bonded fibre and fibre products by utilisation of an improved process for neutralising the catalyst employed in forming the A stage phenol-aldehyde resin or condensate. This condensate is the actual bonding agent which, when incorporated in a diluted form in a binder composition and sprayed onto the fibres and subsequently heated in an oven, cures and bonds the fibres to one another. The condensate is a phenol-aldehyde condensate which is the result of reacting a phenol and an aldehyde in the presence of an alkali metal or alkaline earth metal hydroxide as catalyst to form an A stage or resole resin. The catalyst, once the reaction has been completed, is then neutralised, either before or after dilution, with an acidic lignosulphonate, or a liquor containing such material. An organic or mineral acid can be utilised in conjunction with the lignosulphonate, or lignosulphonate liquor, so as to avoid adding excessive amounts of lignosulphonate.
