    Abstract: Method and apparatus for mixing foundry mold catalyst and carrier gas when the catalyst is in the liquid phase and the carrier is in the gaseous phase at standard conditions of temperature and pressure. The catalyst liquid is heated to vaporize it and the resulting catalyst gas is then mixed with the carrier gas under control of an automatic gas flow regulator which maintains the mass ratio between the catalyst gas and the carrier gas at the desired level in the gaseous mixture notwithstanding variations in the flow rate of either or both gases. The gaseous mixture is then blown through foundry molds and cores to cure the resin binder therein.

    Abstract translation: 当催化剂处于液相并且载体在标准温度和压力条件下处于气相时,用于混合铸造模具催化剂和载气的方法和装置。 催化剂液体被加热以使其汽化,然后在自动气体流量调节器的控制下将所得催化剂气体与载气混合,自动气体流量调节器将气体混合物中的催化剂气体和载气之间的质量比保持在所需水平,尽管 一种或两种气体的流量变化。 然后将气体混合物通过铸造模具和芯体吹塑以固化其中的树脂粘合剂。
