An electromagnetically operated fuel injector includes a disk-type armature and a ball-type valve joined to the armature. The response characteristics and speed of the injector's ball valve are improved by modifying the surface structure of the valve ball to reduce its mass. Preferably a plurality of plunge-ground "flats" are formed on the surface of the ball.

To unravel a terminal portion of a textile yarn, in particular in preparation for joining that yarn to another one by twisting their ends together, an extremity of the yarn is vibrated to loosen the fibers while a part of the yarn spaced from its end is held fast and the yarn extremity is combed or subjected to an aspirated air stream to remove loose fibers. In a preferred arrangement the air stre...

A method for making metallic glass powder is disclosed. A jet of a molten glass forming metal alloy is impinged under an acute angle against the inner surface of a rotating cylindrical chill body, whereon it is atomized into a stream of droplets of molten alloy, which again impinge on the chill surface to be rapidly quenched into metallic glass powder.

Liquid flame-retardants for polyurethane compositions are disclosed. The liquid flame-retardants contain a mixture of a bromohydrin of pentaerythritol, a polyhydric alcohol, and a sufficient amount of a flame-retardant organo-phosphorus compound to render the mixture a substantially solids-free liquid at 25 DEG C., one atmosphere pressure. Illustrative of these flame-retardants is a solution of 2...
