ABSTRACT:
A housing is formed with a quieting chamber which opens in one direction into a mold and with a mixing chamber opening in another direction at right angles to the first-mentioned direction into the quieting chamber. A pair of reactive components are introduced into the mixing chamber to form a mixture therein. Thereupon a mixing piston or plunger is shifted along this mixing chamber at right angles to the quieting chamber so as to force the mixture out of the mixing chamber and into the quiescence chamber. This piston at the end of its stroke lies with is end face flush and contiguous with a planar inner surface of the quieting chamber. Thereupon a displacement piston or plunger moves the full length of the quieting chamber so as to press the mixture from this chamber into the mold. The quieting chamber has the cross-sectional shape of a circular segment and the mixing chamber is of uniform circular cross-section.
