There is measured the length of a thread withdrawn overhead from a spinning cop or from a yarn bobbin. In order to circumvent the fault sources caused by slip and/or thread elongation there is generated a signal which periodically varies in accordance with the movement of the thread release or detachment point at the spinning cop or at the yarn bobbin, as the case may be, and there are counted the...

The herbicide phenmedipham is prepared from meta-aminophenol by reaction with phosgene in an alkyl alkanoate solvent to make meta-hydroxyphenylcarbamic acid chloride, followed by reaction of the chloride with methanol and then reaction of the obtained methyl meta-hydroxyphenylcarbamate with meta-tolyl isocyanate, to obtain the required methyl 3-m- toylcarbamoyloxyphenyl-carbonate.

A flexible, flame-retardant polyetherurethane foam is produced by reacting, under foam-forming conditions, a polymeric polyol component (optionally including a non-halogenated diol), an organic polyisocyanate, an isocyanate-reactive additive to act as a flame-retardant, and one or more non-isocyanate-reactive compounds of phosphorus and nitrogen to act an intumescent agents. Foams so made are resi...

A reinforced reaction injection molding of polyurethanes is prepared by reacting an organic polyisocyanate, a polyoxyalkylene polyether polyol, a chain extending agent, a catalyst, optionally a blowing agent and glass fibers. The glass fibers form a stabilized dispersion in the polyol by employing as a suspending agent the reaction product of a polyamine and a polyester.

An indicium for a rubber article having at least one narrow groove therein, the indicium being made of a rubber of a first color such that the narrow groove is perceived as a narrow line of a contrasting color and a method for making same.

An umbrella cover (10, 100) is provided in which a sleeve (10, 100) contains a substantially rigid telescoping support rod (20) which enables the cover (10, 100) to be readily mounted on an umbrella canopy (12) while facilitating compact storage of the cover (10, 100). The lower end of the sleeve (10) may include a flap portion (16) which is folded back to form a cuff (24) prior to lifting the cov...

An industrial wastewater treatment method is described whereby heavy metals dissolved in the wastewater are precipitated as a slurry which, when allowed to settle, will form a sludge containing at least 10 weight percent solids. In the method, an aqueous suspension or solution of a neutralizing agent is introduced into a first reactor. A suspension containing particles of carrier agent is also int...

The invention relates to a process of making articles of foamed polymethyl methacrylate (PMMA). In a first process stage a mixture comprising monomeric methyl methacrylate, plasticizer, preferably liquid foaming agent and catalyst is polymerized by heating and/or irradiation to form a foaming agent-containing solid body. In the second process stage this body is foamed by heating to the softening t...
