  • Patent number: 4865467
    Abstract: A roll-formed bushing for sliding surface bearings has no machining allowance in the bearing bore and is made of a strip section and has a butt joint that extends throughout the width of the bearing. In order to reduce the allowances of the bore diameter and the outside diameter of the bearing bushing, the butt joint has been closed by charge carrier beam welding.

  • Patent number: 4200585
    Abstract: Acid esters of propylene oxide poly-adducts and their salts, which are obtained by an addition reaction of(a) propylene oxide with(b) a polyfunction amine, which contains 2 to 9 carbon atoms and at least a second reactive amino group or at least one hydroxyl group, and esterification of the poly-adduct with(c) an oxy-acid which is at least dibasic or with a functional derivative of this acid and, if appropriate, by conversion of the resulting acid ester into a salt.These acid esters of propylene oxide poly-adducts are particularly effective as dyeing auxiliaries, especially as dispersing and levelling agents for dyeing synthetic fibres and primarily for dyeing linear polyester fibres.

  • Patent number: 4063916
    Abstract: A process of making glass beads which comprises the steps of forming a fluid medium comprising an aqueous liquid having glass-forming material therein at least most of which is dissolved in the aqueous liquid, forming drops of such fluid medium, and converting the drops to glass beads by causing the drops to travel in separated condition first through a firing zone at glass-forming temperature to cause evaporation of liquid and formation of glass from the glass-forming material, and then through a cooling zone to cause the glass to solidify.

  • Patent number: 4059423
    Abstract: A process for the preparation of expansible beads which are convertible by firing into cellular glass bodies, such process comprising the steps of preparing a slip having a liquid medium continuous phase and a disperse phase, the slip containing particles of glass or glass-forming material, a cellulating agent, and a binder, the disperse phase of the slip including at least most of the particles, dividing the slip into drops, and subjecting the drops while in divided condition to a heat treatment including heating and cooling stages so as to cause evaporation of liquid from the drops and conversion thereof into self-sustaining beads in which the glass or glass-forming particles are held together by the binder and which contain the cellulating agent or gas derived therefrom.
